Dr. Singto Siriwiroj

Dr. Singto Siriwiroj (Thai: นพ.สิงโต ศิริวิโรจน์) is a Thai board-certified plastic surgeon based in Phuket. Khon Kaen University is where he studied medicine and where he completed both of his specialist certificates: surgery in 2018 and plastic surgery in 2022. The Phuket Plastic Surgery Institute (PPSI), run by Bangkok Hospital Siriroj on Chalermprakiat Rama 9 Road, counts him among the five plastic surgeons in its doctor directory. Bangkok Hospital Phuket, on Hongyok Utis Road, keeps a separate profile for him that places him in its Emergency & Trauma Center, with plastic surgery as his specialty.

On his PPSI profile, his cosmetic and gender-affirming procedure areas are set out as:

• eyelid surgery on both lids: upper blepharoplasty and lower blepharoplasty
• breast surgery, meaning breast augmentation, the breast lift and revision breast surgery (our page for the last is breast implant revision)
• gynecomastia correction, which PPSI calls male breast reduction surgery
• gender-affirming surgery for trans women (male-to-female), delivered at PPSI as genital surgery and described on our site under vaginoplasty
• aesthetic surgery of the female genitals

The same profile adds two reconstructive interests: surgery for skin cancer, and the care of maxillofacial (face and jaw) injuries and wounds. Those fit with his trauma-centre listing at Bangkok Hospital Phuket. For gender-affirming surgery, an article PPSI published for its tenth anniversary credits him and the institute's director, Dr. Sanguan Kunaporn, with a vaginoplasty method built on a free jejunal graft (a piece of small bowel), named by PPSI the 'GRS Phuket Technique'. That is the institute's own account, and we return to it under current roles below.

The ThPRS member register includes him, and Bangkok Hospital Siriroj records English and Thai as his languages. If you want an appointment with him in Phuket, the first step is to request a consultation: the details you give us go to the hospital, our patient team finds out when Dr. Singto is free, and we write back with what is on offer. No appointment is fixed until the hospital itself confirms it.

This profile draws on his English and Thai PPSI pages, his Bangkok Hospital Siriroj and Bangkok Hospital Phuket pages, his ThPRS member entry and one PubMed record, every one of them reopened on 27 September 2026. When something patients often ask about is missing from those sources, this page names the gap instead of filling it. How we build and check profiles is set out in our research methodology.

Dr. Singto's published training took place at a single university from start to finish.

• 2013, medical degree. Khon Kaen University's Faculty of Medicine awarded him his Doctor of Medicine. The Thai version of his PPSI profile adds that the degree carried second-class honours.
• 2018, surgery. After a surgical residency at Khon Kaen University he received the Thai board certificate in surgery, recorded on the Thai PPSI profile as วุฒิบัตร สาขาศัลยศาสตร์.
• 2022, plastic surgery. A further residency at the same university, this time in plastic surgery, ended with his second Thai board certificate, this one in plastic surgery, which the Thai PPSI page also attributes to Khon Kaen University.

PPSI's English-language page words the two certificates as 'Thai Certified Board of Surgery' and 'Thai Certified Board of Plastic Surgery'. His profiles at Bangkok Hospital Siriroj and Bangkok Hospital Phuket give the same two residencies with the same years, so all three hospital sources line up. None of them names a fellowship or any training outside Thailand, and this page does not add one.

Published research. One paper on PubMed lists him as first author: 'The Effect of Presurgical Nasoalveolar Molding on Oronasal Fistula Following Primary Palatoplasty', in The Journal of Craniofacial Surgery (2023). Its affiliation is the Plastic & Reconstructive Unit of the Department of Surgery at Khon Kaen University's Faculty of Medicine, the unit where he trained in plastic surgery. As its title shows, it concerns cleft palate repair. It reflects research from his residency years rather than a service advertised in Phuket, and it is the only PubMed record we found under his surname.

Society membership. His name, นายแพทย์สิงโต ศิริวิโรจน์ (Singto Siriwiroj), appears among the members of ThPRS, the national body formally called The Society of Plastic and Reconstructive Surgeons of Thailand. February 2024 is the date shown on his entry, and we checked it. At an institutional level, PPSI claims ISAPS membership (the International Society of Aesthetic Plastic Surgery) for all of its plastic surgeons. That claim is not repeated on any of his individual profiles, and his name did not come up among the Thailand results of the ISAPS surgeon search we ran on 27 September 2026. Where ISAPS membership weighs in your decision, ask us to get PPSI's confirmation for him by name.

Medical licence. No licence number is shown on his PPSI, Bangkok Hospital Siriroj or Bangkok Hospital Phuket profiles, and his ThPRS entry has no licence field. When we typed his name into the Thai Medical Council's doctor register (27 September 2026), the site's Cloudflare block page halted the search before any result loaded, so there is no register finding to report. The register is free to use: search it with his Thai name, สิงโต ศิริวิโรจน์, or ask our patient team to request his licence details from the hospital.

Two hospital listings describe Dr. Singto's current work. Neither says when he started.

• Plastic surgeon at PPSI, Bangkok Hospital Siriroj. Bangkok Hospital Siriroj places him within its Phuket Plastic Surgery Institute centre. His eyelid, breast, gynecomastia, genital aesthetic and gender-affirming procedure areas are listed on the PPSI profile.
• Plastic surgeon in the Emergency & Trauma Center, Bangkok Hospital Phuket. This listing gives plastic surgery as his specialty and English as his language.

The institute he works in. By PPSI's own account it opened on 21 March 2016, which makes 2026 its tenth year. The institute merged two older cosmetic surgery units. One was the Phuket International Aesthetic Center (PIAC), at the hospital now named Bangkok Hospital Siriroj; the other was BPICS, the Bangkok Phuket Institute of Cosmetic Surgery, which operated inside Bangkok Hospital Phuket. Management now sits with Bangkok Hospital Siriroj, one of the hospitals in the BDMS group (Bangkok Dusit Medical Services), and the director is Dr. Sanguan Kunaporn. The five plastic surgeons in PPSI's directory are Dr. Sanguan, Dr. Singto, Dr. Piyapas Pichaichanarong, Dr. Veerawat Tirananmongkol and Dr. Pongsatorn Sanguanchua. PPSI's contact page gives only the Bangkok Hospital Siriroj address.

The 'GRS Phuket Technique'. PPSI's tenth-anniversary article describes a neovaginoplasty method in which the vaginal lining is made from a free graft of jejunum, part of the small intestine, and attributes it to Dr. Sanguan Kunaporn and Dr. Singto (the article spells his surname 'Siriwirote'). This is the institute's own publication, not an independent assessment. We found no PubMed paper by Dr. Singto on the method. If it is relevant to you, ask him who it is intended for, how often he has used it, and how its recovery and follow-up differ from the other approaches PPSI offers.

Gaps in the public record. His PPSI profile carries no biography, and none of his official profiles sets out a career history, says how long he has practised, or counts the operations he has done. What can be dated is his plastic surgery certificate, awarded in 2022. We state that as a fact, not a verdict. It simply makes the experience questions in the consultation section below more worth asking, and a surgeon at any career stage should answer them openly.

Each area below is one his PPSI profile names. The general points come from our procedure guides and describe what applies to most patients; your own suitability, and the version of any operation that fits you, depend on his examination.

Eyelid surgery: upper and lower blepharoplasty

His profile covers surgery on both the upper and the lower lids. In general, upper eyelid surgery takes away surplus skin that hoods the lid, sometimes with a little fat, through a cut hidden in the natural crease; where the lids hang low enough to get in the way of sight, it may also open up the view upward. Lower eyelid surgery deals with puffy under-eye bags and slack skin below the eye. The surgeon can reach the fat through a fine skin incision tucked under the lower lashes, or via the moist inner lining that faces the eyeball (the transconjunctival approach, which leaves no outer scar), and may remove that fat or reposition it.

Most eyelid operations, according to our blepharoplasty page, need no overnight stay; patients have local anaesthetic with sedation or go under a general anaesthetic. In general, sutures are taken out about 5–7 days after the operation, the point at which many visitors from abroad head home, with bruising mostly gone within 1–2 weeks. Risks include dry or irritated eyes, asymmetry and, after lower-lid surgery, a change in the position of the lid margin; our blepharoplasty guide explains these in more detail.

Two points to clarify with Dr. Singto. His profile does not name double eyelid surgery or ptosis correction (for a lid margin that droops because the lifting muscle is weak), so if either is what you are after, ask whether he does it himself or would refer you. And a brow that sits low can make the lids look heavier than they are, so ask him to judge whether your brow is part of the picture before you settle on eyelid surgery alone.

Breast augmentation

His profile includes breast augmentation. In general, it enlarges or reshapes the breasts; implants filled with silicone gel or saline are the usual method, and fat transferred from elsewhere on the body is an alternative for some. The decisions to talk through are the implant fill, its shape (round or anatomical), its surface, where the scar will go (the breast crease, the areola border or the armpit) and how deep the implant is placed, over the pectoral muscle or partly under it. Surface is also a safety question, because BIA-ALCL, an uncommon lymphoma, shows a stronger association with certain textured implants. Implants also wear or cause problems over time, so plan for the possibility of another operation later in life.

In general, augmentation is done under general anaesthesia with discharge the same day or after one night, a 7–10 day stay in Thailand is typical for visitors, desk work often resumes after about a week and strenuous exercise usually waits about six weeks. Ask Dr. Singto which implant brands PPSI uses, what he would suggest for your frame and why, and keep the implant card you are given: any future surgeon will need it.

Breast lift

A breast lift (mastopexy) raises and reshapes breasts that have dropped, by trimming excess skin and moving the nipple and underlying tissue higher. It improves shape rather than size. The scar depends on how much lift is needed: a circle at the areola edge only, that circle plus a vertical line down to the crease (the 'lollipop'), or an inverted-T 'anchor' that runs along the crease as well. If you want more fullness as well, an implant can go in during the same operation or at a later one. Doing both at once is a bigger undertaking, and further surgery is needed more often after the combination than after either procedure by itself, so ask Dr. Singto which route he would take for you.

In general, the lift is performed under general anaesthesia. Visitors from abroad often set aside 10–14 days for the trip; the supportive bra stays on for several weeks, while the scars keep fading for 12–18 months. PPSI also describes a lift that uses the patient's own breast tissue for volume instead of an implant, presented as a technique of its director, Dr. Sanguan; if that interests you, ask whether Dr. Singto performs it or would refer you.

Revision breast surgery

Revision breast surgery appears on his profile with no specific operations named. We cover it under breast implant revision, and capsular contracture correction is a closely related page. In general, people seek revision because scar tissue has tightened around an implant (capsular contracture), an implant has ruptured, rippling or asymmetry has appeared, or they want a different size. The plan rests on what was done before, so bring the original operative record, your implant details and any scan reports. A revision is much harder to plan without them, and a surgeon may need them before agreeing to operate.

Gynecomastia correction

Gynecomastia surgery flattens a chest enlarged by male breast tissue. In general, a medical cause is looked for first, since hormone changes, certain medicines, anabolic steroids, alcohol or an underlying illness can all contribute. Where the fullness is mostly fat, liposuction may be enough; firm gland is usually cut out through a small incision along the lower border of the areola; many chests need both, and a few need loose skin removed too. Most patients go home the same day, after either a general anaesthetic or local anaesthetic combined with sedation. Overseas patients commonly stay 7–10 days, a compression vest stays on for several weeks, and chest training usually resumes after 4–6 weeks. Ask about the chance of an uneven contour and how it would be managed. PPSI does not provide the vest, but its staff help patients find one, so sort it out before your surgery date.

Male-to-female gender-affirming surgery

His PPSI profile lists gender-affirming surgery for male-to-female patients. At PPSI this service is genital surgery, which our site covers under vaginoplasty. The institute's Gender Change page names two approaches: penile inversion, using the penile skin together with a full-thickness skin graft taken at the same operation, and a colon (sigmoid) segment where extra depth is needed. The anniversary article adds the jejunal-graft 'GRS Phuket Technique' credited to Dr. Sanguan and Dr. Singto. Nothing on his profile says which of the three he chooses for which patient, so start your questions there.

As a general picture, this is a long operation under general anaesthesia, and an orchiectomy (the testes are removed) is normally performed during it as well. Patients commonly spend 5–7 nights in hospital and three to four weeks in Thailand, desk work often resumes after around 6–8 weeks, and the new canal must be dilated for the long term or its depth can be lost. Because skin used inside the canal should be hair-free, many surgeons require permanent hair removal first; it needs repeated sessions, so begin well ahead. A zero-depth option (vulvoplasty) avoids lifelong dilation; ask whether it is available if you do not want a canal. Before surgery, PPSI's requirements are a medical check-up no more than three months old, a supporting letter from a GP or psychologist for overseas patients, and hormone therapy stopped ahead of the operation.

Female genital aesthetic surgery

His profile names this area but no individual operations. PPSI's service pages cover labiaplasty, cosmetic vaginal tightening, perineoplasty and clitoral hood reduction, so ask which of those Dr. Singto carries out himself. Labiaplasty, in general, involves no overnight stay; it can be carried out with the area numbed plus sedation, or with a general anaesthetic, and travellers commonly allow 5–7 days in Thailand. Tissue that has been taken away cannot easily be restored, so a cautious plan is safer than an aggressive one. This is cosmetic gynaecology, which is separate from gender-affirming surgery.

Skin cancer surgery, facial injuries and wound care

We have no guides for these reconstructive areas. They are normally organised through the hospital as medical care rather than planned as elective travel. If you are hurt while in Phuket, go directly to a hospital emergency department; an online consultation request is not the right route for an injury.

When you meet, Dr. Singto examines you, explains what he would advise and why, and sets out the alternatives. No case numbers, outcome figures or patient photographs are published on his profiles, so your own questions carry more of the load than usual. Keep a written record of his answers, or ask him to put the key points in writing.

Whatever the procedure

• How many of these operations do you do in a typical year, and would mine be done at PPSI in Bangkok Hospital Siriroj or at Bangkok Hospital Phuket?
• Who will give my anaesthetic, and what kind do you advise? (According to PPSI, anaesthesiologists there look after patients on a one-to-one basis.)
• How many nights should I book in Phuket, and on which day after surgery are your patients usually fit for the flight home?
• What does the written quote cover: tests, garments, medicines, nights in hospital, and check-ups after surgery?
• Who looks after me if trouble starts after I have flown home? PPSI publishes check-ups at one, three, six and twelve months, online contact through its coordinator, and a 'surgical promise': if you report a complication or are unhappy within 12 months, your own surgeon looks at it first, and complex cases go to a Surgical Review and Risk Management Committee, which decides where responsibility lies for any revision one case at a time. How would that apply to my operation?

Eyelids

• What is making my eyes look heavy: surplus skin, fat pads, brow position or a weak lifting muscle?
• On my lower lids, do you favour an external incision or the hidden transconjunctival route?
• Do dry eyes, glaucoma, thyroid eye disease or wearing contact lenses change your plan for me?

Breasts, including revision

• Which kind of implant (fill, shape, surface) fits my body and goals, and what drives that choice?
• Which incision site suits me, and at what depth, relative to the pectoral muscle, would the implant go?
• If I need lift as well as volume, do you prefer a single-stage or a staged plan?
• In a revision, what is your explanation for what went wrong, would you take out the capsule, and would you exchange the implant or leave it out?

Gynecomastia

• Is my chest mostly gland, mostly fat or a mix, and do I need blood tests first?
• Is skin removal likely in my case?

Vaginoplasty

• Which technique do you use most: penile inversion with a skin graft, a colon segment, or the jejunal graft PPSI describes? Which would you choose for my anatomy, and why?
• What hair removal do you need completed, and by what date?
• When do I stop my hormones, and when may I start them again?
• What letters and tests are required, what will dilation involve day to day, and can I take home an English copy of the operation record for the doctors who will look after me?

Female genital aesthetic surgery

• Which of PPSI's genital aesthetic procedures do you perform yourself?
• How much tissue would you plan to remove, and how would we agree on it beforehand?

3D simulation. From your photographs, PPSI's Crisalix software can model how a change might look. Treat the image as a talking point for setting goals with Dr. Singto; your healed result may differ from it.

Which hospital, which address. PPSI, where his cosmetic, breast and gender-affirming work is listed, is housed in Bangkok Hospital Siriroj; PPSI's contact page places it at No. 44, Chalermprakiat Rama 9 Road, in Wichit subdistrict (Mueang Phuket district), postcode 83000. Bangkok Hospital Phuket, where his listing is under the Emergency & Trauma Center, is a different site at 2/1 Hongyok Utis Road, Muang District, Phuket 83000, with its own international patient desk. Check which of the two your appointment and any operation are booked at before choosing a hotel. For the island as a place to recover, see our Phuket page.

Accreditation. Accreditation here belongs to the host hospital. On 27 September 2026 the Joint Commission International directory showed Bangkok Hospital Siriroj, which administers PPSI, as JCI-accredited under the Hospital Program, dated effective from 15 December 2012; the entry showed no expiry. That record is the hospital's; it is not a separate accreditation of PPSI itself. On theatre design, PPSI states that positive-pressure systems are installed in its operating rooms.

Languages. Bangkok Hospital Siriroj records English and Thai for Dr. Singto, and Bangkok Hospital Phuket records English. For overseas patients, PPSI says its coordinators work in English, Chinese and French. Should neither Thai nor English suit you, note the language you want on your request so an interpreter can be discussed with the hospital early.

Services PPSI lists for patients from abroad

• Airport pick-up plus hotel-to-hospital runs, using cars and drivers employed by PPSI. These are free above a procedure value that PPSI sets and charged below it; two FAQ answers on its site give different thresholds, so ask which one applies now.
• Hotel suggestions from the PPSI team.
• A video consultation with a plastic surgeon before you travel, ending with a surgical recommendation and a quoted price.
• Follow-up appointments planned for the first, third, sixth and twelfth month; should something go wrong after you fly home, PPSI's coordinator can set up an online review.
• Payment in cash, by credit card or by transfer to an Australian or other overseas bank account, with the full amount due before admission.
• No compression garments or support bras in the package, although PPSI helps patients find suitable ones. Budget and plan for this after breast or chest surgery.

Length of stay. Our procedure guides give general ranges for time in the country: roughly 5–7 days for an eyelid operation or labiaplasty, 7–10 days for breast augmentation or gynecomastia surgery, 10–14 days for a breast lift, and three to four weeks for vaginoplasty. These are planning ranges, not promises. Dr. Singto decides when you are fit to travel, and slow healing or a complication can lengthen your stay, so book a flight home that you can change.

What to bring. After eyelid surgery you will want sunglasses, and eye make-up and swimming wait until he clears you. After breast or chest surgery, pack tops that open at the front and your support bra or compression vest (keep it on for the flight if advised), and arrange help with lifting luggage. For vaginoplasty, choose private accommodation with space to rest for several weeks, and think about travelling with a companion. For any operation, Phuket's sea and pools are off limits until your wounds have healed and your surgeon agrees.

Good information in advance lets Dr. Singto give a more useful opinion, whether by video before you travel or face to face in Phuket. Whatever the procedure, include:

• your age, height, weight and any medical conditions
• every medicine you take, including hormones, vitamins and herbal products, plus any allergies
• whether you smoke or vape, and how much
• past surgery, above all in the area you want treated, with the year and any hospital paperwork you still have
• the dates you could travel, plus a hospital preference if you have one
• a few lines describing the concern in your own words and the change you hope for

Eyelids. Close-up photos of both eyes in soft natural light, bare-faced and with glasses off, in four poses: gazing forward, lids gently shut, eyes turned up, and each profile. Flag dry-eye symptoms, glaucoma or thyroid eye trouble if you have had them, say whether you wear contact lenses, and give roughly when an optometrist or eye doctor last checked your eyes.

Breast augmentation or lift. Standing photos from neck to waist with your arms relaxed, facing the camera, turned fully to each side and turned halfway to each side. Add your current bra size, the size or shape you have in mind, any breast lumps or earlier breast imaging, and whether you expect to have children or breastfeed in future.

Revision breast surgery. All of the above, plus the implant card (brand, size, type and lot number), notes from the original operation and any scan reports, especially if a rupture or capsular contracture has been suspected.

Gynecomastia. Shirtless chest photos: straight on, both profiles and both diagonals. List current medicines, any anabolic steroid use past or present, and results of hormone or blood tests your own doctor has arranged.

Vaginoplasty. Your recommendation letter from a GP or psychologist (PPSI asks patients from abroad for one), your hormone history, how far your hair removal has progressed, and details of any earlier genital or gender-affirming surgery. PPSI also wants a health check-up done within three months before the operation, so ask what it should cover and time it around your dates.

Female genital aesthetic surgery. A brief written description of the concern, for instance discomfort in clothing or during sport, appearance, or both, plus any childbirth history or previous gynaecological operations.

For any genital procedure, hold back intimate photos until the patient team asks for them, and check how they will be shared with the hospital. Keep a copy of everything you send, because your own doctor at home will want it later.
