Dr. Suphalerk Lohasammakul

Dr. Suphalerk Lohasammakul (Thai: นพ. ศุภฤกษ์ โลหะสัมมากุล) is a Thai board-certified plastic surgeon in Bangkok. His hospital base is Bumrungrad International Hospital, a private hospital whose Plastic Surgery Center names 'Plastic Cosmetic & Reconstructive Surgery' as his field. Bumrungrad publishes his name as Suphalerk Lohasammakul, M.D., with no academic rank. Thai doctors are normally addressed by their given name, so at the hospital he is likely to be called Dr. Suphalerk.

His documented record leans towards reconstructive plastic surgery. He qualified in medicine at Mahidol University in 2013 and received the Thai Board of Plastic Surgery certificate in 2021. He then trained abroad twice: in the International Visiting Scholars Training Program of the Department of Plastic Surgery at Asan Medical Center, South Korea (2023), and as a fellow in microvascular reconstructive surgery at Corewell Health William Beaumont University Hospital in the United States (2024). His papers indexed on PubMed deal mainly with breast reconstruction after cancer and with the anatomy and blood supply of the tissue flaps used in reconstruction.

Three points are worth knowing before you ask for him by name:

• Bumrungrad does not publish a procedure list for him. His hospital profile names no special clinical interests and no procedures. 'Plastic Cosmetic & Reconstructive Surgery' is the label Bumrungrad gives most of its plastic surgeons, so on its own it does not tell you which operations he personally performs. For that reason our site does not link him to any procedure page yet.
• His published clinic time is short. His profile gives a single weekly outpatient slot, Tuesday evening from 17:00 to 19:00, held at the centre on level 16 of Building A (shown on the schedule as '16A'). Schedules change, and our patient team rechecks it with the hospital for each request.
• Bumrungrad is the only practice we list. Journal papers he co-authored name Siriraj Hospital's medical faculty at Mahidol University among his affiliations. Ask our patient team whether he treats patients at Siriraj today; we do not arrange appointments there.

Two professional bodies include him in their published records. He holds ThPRS membership; that society, which represents plastic and reconstructive surgeons in Thailand, shows an entry for him on its website dated 6 February 2024, and a surname search (โลหะสัมมากุล) in the member list of RCST, the Thai Royal College of Surgeons, also brings up his entry. Thai and English are the languages shown on his Bumrungrad profile.

To find out whether he would see you, send a consultation request for Dr. Suphalerk Lohasammakul. Our patient team puts your question to Bumrungrad, including whether your problem is one he treats; an appointment stands only after the hospital confirms it.

Every qualification below is taken from Dr. Suphalerk's English and Thai profiles on the Bumrungrad website. Dates on the Thai-language version follow the Buddhist era (2556, 2564, 2566 and 2567), equivalent to 2013, 2021, 2023 and 2024.

Doctor of Medicine, Mahidol University (2013). Mahidol University awarded his Doctor of Medicine with Second-Class Honors, according to both language versions of the profile.

Thai Board of Plastic Surgery (2021). The Thai-language profile dates it to 2564. In Thailand, the board certificate in plastic surgery is the specialist qualification awarded after residency training and examination, and it is the credential to look for when checking that a doctor offering cosmetic or reconstructive surgery is a trained plastic surgeon. Where he did his residency is not stated on the profile, and we have not guessed.

International Visiting Scholars Training Program, Asan Medical Center, South Korea (2023). Bumrungrad lists this under 'Special Clinical Trainings', with the Department of Plastic Surgery. Author affiliations on his 2024 to 2026 papers include Asan Medical Center, University of Ulsan College of Medicine, Seoul, which matches this period of training.

Fellowship in Microvascular Reconstructive Surgery, Corewell Health William Beaumont University Hospital, United States (2024). This is the most specific item on his record, and his papers give the hospital's location as Royal Oak, Michigan. In general, a fellowship is additional training taken after specialist certification. Microvascular reconstructive surgery, often shortened to microsurgery, moves a block of the patient's own tissue (skin, fat, muscle or bone) together with its artery and vein, and reconnects those vessels at the new site under an operating microscope. Surgeons use these 'free flaps' to rebuild a breast after mastectomy, to cover wounds that cannot close with nearby tissue, and to reconstruct the head, neck or limbs after cancer or injury.

What the record does not show. Bumrungrad publishes no years-of-practice figure, case numbers, awards or academic rank for him, and we have added none. The licence can be looked up on the Medical Council of Thailand's public register at checkmd.tmc.or.th, and our patient team can help you confirm it before you travel. His board certificate comes from the hospital profile, and the two society memberships were matched on the ThPRS and RCST websites. Patients who want a licence confirmation can ask our patient team to request it from Bumrungrad, or look him up on the council's site directly. Our provider research methodology describes the sources and checks behind each statement on this profile.

Bumrungrad International Hospital, Bangkok (current). Dr. Suphalerk Lohasammakul is listed as a plastic surgeon in Plastic Cosmetic & Reconstructive Surgery at the hospital's Plastic Surgery Center, which Bumrungrad locates in Building A, 16th floor; his schedule abbreviates this to '16A'. On its own page the centre says it handles cosmetic and reconstructive operations as well as hair transplantation, treats both men and women, and books all doctor consultations in advance. His published outpatient time, as shown on 27 September 2026, is Tuesday from 17:00 to 19:00. His profile page is live, but when we checked he was not returned by the hospital's older specialty search and was not in the surgeon list on the centre's main page, so patients searching Bumrungrad's site by specialty may not find him.

Faculty of Medicine Siriraj Hospital, Mahidol University (research affiliation). His PubMed-indexed papers give Siriraj affiliations: the Department of Anatomy on papers from 2017 and 2018 and again from 2023 to 2026; the Department of Surgery's divisions of Plastic and Reconstructive Surgery and of Head, Neck and Breast Surgery on a 2026 paper; and the Siriraj Cancer Center on another 2026 paper. These are affiliations printed in journals, not a hospital staff listing. We therefore do not describe his current role at Siriraj, and we cannot arrange appointments there. Siriraj Piyamaharajkarun Hospital, the private hospital on the Siriraj campus, did not list him in its find-a-doctor directory on 27 September 2026.

Research. PubMed returns 23 records under his author name. The plastic surgery papers include:

• a 2026 Gland Surgery paper comparing outcomes of three implant-based approaches in breast cancer patients: reconstruction using acellular dermal matrix, reconstruction using no matrix, and reconstruction using TiLOOP® mesh;
• a 2026 review in Plastic and Reconstructive Surgery of ten years of hybrid DIEP flap plus implant breast reconstruction, analysing risk factors associated with flap failure;
• a 2026 study in the Journal of Reconstructive Microsurgery of how breast and nipple position change over time after reconstruction with the patient's own tissue in an Asian population;
• a 2025 updated classification, in Plastic and Reconstructive Surgery Global Open, of vessel branching and perforator patterns relevant to robotic-assisted DIEP flaps;
• a 2025 proof-of-concept paper in Plastic and Reconstructive Surgery on an ultrathin parascapular flap used to reconstruct the sole of the foot;
• a 2024 study in the Journal of Reconstructive Microsurgery of the superficial inferior epigastric artery flap, its vascular pattern and its territory across the midline;
• a 2023 paper in PLoS One on redesigning the septal L-strut in septorhinoplasty for strength and stability;
• a 2018 paper in Plastic and Reconstructive Surgery on an additional arterial connection (the inferior external pudendal artery) to reduce skin necrosis after penile replantation.

Being an author on a paper is not the same as offering that operation to private patients. The list shows where his academic work lies; which procedures he takes on at Bumrungrad is for the hospital to confirm, case by case.

Bumrungrad's profile for Dr. Suphalerk Lohasammakul lists no procedures, so this section is not a menu of operations. It sets out the areas his verified training and research point to, what the centre where he works offers, and what to confirm before planning a trip around him. The general information describes each area in general terms; his own techniques and results are not published.

Microvascular reconstructive surgery

This is the one area named in his qualifications, through his 2024 fellowship. In general, microsurgical reconstruction is used when a defect is too large or complex to close with nearby tissue: after cancer surgery, after trauma, or for wounds that will not heal. His papers on the ultrathin parascapular flap (tissue from the upper back, used in that paper to resurface the sole of the foot) and on the superficial inferior epigastric artery flap (tissue from the lower abdomen) belong to this field.

Bumrungrad's Plastic Surgery Center lists reconstructive services including breast reconstruction, post-cancer reconstruction, hand surgery, facial bone and maxillofacial reconstruction, and paediatric reconstruction. The hospital does not say which surgeon handles each. If you need reconstruction, tell our patient team what needs repairing and why, and send your medical reports; the team asks the hospital whether Dr. Suphalerk would see you for it. Reconstructive cases usually begin with a review of records rather than photos alone, because the plan depends on the original disease or injury and on any treatment still to come.

Breast reconstruction after mastectomy

Breast reconstruction is the subject of most of his recent papers: implants supported by acellular dermal matrix or TiLOOP® mesh compared with implants alone, hybrid reconstruction combining a DIEP flap with an implant, and how breast and nipple position change after reconstruction with the patient's own tissue in Asian patients. It is not listed as a service on his profile, but it is listed by the Plastic Surgery Center, and Bumrungrad also runs a Breast Center. The Joint Commission International directory shows the hospital holding a Clinical Care Program Certification for breast cancer, effective 30 May 2025.

In general, three routes exist for rebuilding a breast: an implant, a flap of the person's own tissue, or a flap and implant together. A DIEP (deep inferior epigastric artery perforator) flap takes skin and fat from the lower abdomen with its blood vessels, leaving the abdominal muscle in place, and moves it to the chest by microsurgery. Reconstruction may happen at the same operation as the mastectomy or later, and the timing is shaped by cancer treatment, radiotherapy in particular. For an overseas patient it is rarely a single trip: the plan has to fit with the breast surgeon and oncologist treating the cancer, and later stages such as symmetry adjustments or nipple reconstruction are common. Suitability for any of these options needs an in-person assessment, and like all surgery they carry risks, including problems with the blood supply of a flap. These are questions to put to him directly; his profile does not answer them.

Nose surgery

His 2023 paper in PLoS One looked at redesigning the septal L-strut in septorhinoplasty. When a surgeon reshapes the septum or takes cartilage from it for grafts, an L-shaped strip of cartilage is normally kept along the bridge and at the front of the septum so the nose stays supported; the paper considered how to design that strip for strength and stability. This is a research interest, not a statement that he performs rhinoplasty at Bumrungrad. The Plastic Surgery Center does list augmentation and reduction rhinoplasty, so our patient team can ask whether he takes nose surgery patients. Our rhinoplasty guide explains the operation in general, and septorhinoplasty is the version that also corrects the septum to improve breathing.

Cosmetic surgery

The word 'Cosmetic' in his specialty label reflects the centre he belongs to. Bumrungrad's Plastic Surgery Center lists procedures such as eyelid surgery, breast augmentation, breast reduction, tummy tuck and liposuction, but it does not assign them to named surgeons, and none appears on his profile. If you have a cosmetic procedure in mind, our team can ask whether he performs it. The Bumrungrad hospital page shows which surgeons there have documented procedure areas on our site.

Gender-affirming surgery

Bumrungrad offers gender-affirming surgery through its Pride Clinic, which names four surgeons for it: Asst. Prof. Dr. Poonpissamai Suwajo, Dr. Worawat Kaewwichian, Dr. Krerkwit Visitsakulchai and Dr. Phonlawat Trakunngoenthai (also spelled Trakulngernthai). Dr. Suphalerk is not among them. Phalloplasty in general uses a flap of tissue from the forearm or thigh, and his 2018 paper concerned penile replantation after injury, but neither his microsurgery training nor that paper documents gender-affirming work, and we do not list him for it.

Because Bumrungrad publishes no procedure list for Dr. Suphalerk, the first question is simply whether he sees patients for what you need. Our patient team puts that question to the hospital before anything is booked, so that you do not plan a trip around a Tuesday evening appointment only to be referred to a colleague. After that, the useful questions depend on why you are seeing him.

If you are asking about breast reconstruction

• Which options suit my situation: an implant, my own tissue such as a DIEP flap, or a combination? Why would you choose one over the others for me?
• If you suggest my own tissue, which donor site would you use, and what scar and recovery does that area leave?
• How do my cancer treatment and any radiotherapy, past or planned, affect the timing and the choice of reconstruction?
• Who else is involved (breast surgeon, oncologist, anaesthetist), and how are they coordinated if my cancer is being treated in another country?
• How long is the operation, how long will I stay in hospital, and how is the flap checked in the first days?
• What happens if a flap has a problem with its blood supply after surgery?
• How many further operations are usual, for example to adjust symmetry or rebuild the nipple, and can they be done on a later visit?
• When will I be fit to fly, and who looks after me once I am home?

If you need reconstruction after injury, surgery or a wound that will not heal

• Can the defect be closed with nearby tissue, or do I need a free flap? What are the alternatives?
• Where would the tissue come from, and how will that part of my body look and work afterwards?
• Does anything need to happen first, such as treating infection, finishing cancer treatment or preparing the wound?
• After a free flap, how long must I remain in Bangkok before flying, and who checks the wound once I am home?

If you are asking about nose surgery or a cosmetic procedure

• Do you perform this procedure at Bumrungrad, and how often?
• Which technique and materials do you recommend for me, and why? For nose surgery: would the support come from my own cartilage or from an implant, and should my septum or breathing be corrected at the same time?
• What does the hospital's estimate include, and what would a revision cost?

For any consultation

In general, records and photos sent ahead allow only a provisional opinion, and a final plan follows a face-to-face examination. Ask which items the hospital's estimate covers, which pre-operative tests are needed, and how follow-up will work from your home country. Dr. Suphalerk lists Thai and English; an interpreter for other languages can be requested through the hospital. Taking notes or bringing a companion helps, because reconstruction consultations often cover several options and stages.

Dr. Suphalerk's only published clinic is at Bumrungrad (postal address: 33 Sukhumvit 3, Soi Nana Nua, Wattana district, Bangkok 10110). Each point below comes from Bumrungrad's own pages or from accreditors' online directories, read on 27 September 2026.

• Finding his clinic. The Plastic Surgery Center's check-in is counter A, sixteen storeys up in Building A. Centre hours run from 8.30 until 20.00 on weekdays (weekend hours are shorter, 8.00 to 17.00), and doctor consultations need a prior appointment. Because his own session is a two-hour Tuesday evening slot (17:00 to 19:00), plan to land in Bangkok a day or two before the Tuesday you are given and keep the next Tuesday free in case it has to move.
• Coordination for overseas patients. Six floors below his clinic, on the tenth floor of the same building, is Bumrungrad's Medical Coordination Office, which the hospital runs free of charge for patients from abroad. For a reconstruction enquiry, this is where records such as pathology reports and scans can be reviewed and a cost estimate prepared; the hospital says the same team also books appointments and video consultations, deals with embassies and insurance companies, and, once you are discharged, issues the medical report and fitness-to-fly paperwork you may need at home.
• Interpreters. Dr. Suphalerk's consultations are in Thai or English. Where neither suits you, an interpreter can be requested: Bumrungrad's factsheet puts its interpreter pool at over 130, and its service overview covers languages as varied as Amharic, Bengali, Mandarin, Cantonese, Korean, Mongolian, Nepali, Russian and Urdu, with Cultural Support Officers as a further option for non-English speakers.
• Arriving by air and rail. At Suvarnabhumi, Bumrungrad has a representative stationed in the International Arrival Hall near Exit C, Gate 9, from 7.00 to 23.00 daily. A no-charge van then runs about once an hour to the hospital and neighbouring hotels, although the hospital adds that this depends on the number of passengers. Within the city, its free vans link the hospital every day with two Skytrain stops, Nana and Phrom Phong.
• Staying on after surgery. Reconstructive surgery in general involves an inpatient stay and review visits afterwards, so a longer trip is likely. Bumrungrad's Business Center handles hotel and flight bookings, and visa extensions for patients and the people accompanying them are arranged with Bangkok's immigration office through the hospital. Ask how many nights to allow before buying return tickets.
• Accreditation. In the Joint Commission International directory, Bumrungrad's Hospital Program accreditation carries a first effective date of February 2002, and a breast cancer Clinical Care Program Certification dates from 30 May 2025, which matters to anyone weighing reconstruction there. HA Thailand's advanced re-accreditation for the hospital is valid through 22 May 2029, while Global Healthcare Accreditation (GHA) lists it from 20 September 2017.
• Capacity. For reconstruction that needs theatre time and close monitoring, it is relevant that the hospital's factsheet counts 40 operating theatres alongside 580 inpatient beds, and that its ICU page lists separate medical, surgical, respiratory, paediatric-and-obstetric and coronary care units.

Our Bumrungrad International Hospital profile covers the rest of what the hospital offers.

The aim of a complete request is that Bumrungrad can tell straight away whether Dr. Suphalerk is the surgeon for your problem, without a string of follow-up messages. What helps depends on the reason for your request.

Whatever the reason for your request

• Your age, height and weight, where you live, and the travel dates you have in mind.
• Your health conditions, any allergies, every medicine and supplement you take (mention blood thinners specifically), and your smoking or nicotine use; in general, not smoking is treated as essential for flap survival.
• Any earlier surgery on the part of the body concerned, with copies of the operation notes where available.
• Whether you would like an online first consultation or will be in Bangkok on a Tuesday.

For breast reconstruction

• The pathology report and the operation note from your mastectomy, or the surgical plan if the mastectomy has not yet taken place.
• A summary of your cancer treatment: chemotherapy, radiotherapy (dates and area treated), hormone or targeted therapy, and anything still planned.
• Contact details or a letter from your breast surgeon or oncologist, and recent imaging reports.
• Details of any abdominal surgery, including caesarean sections or liposuction, because the lower abdomen is a common donor site for reconstruction with your own tissue.
• Photos of the chest and, if own-tissue reconstruction is being considered, the abdomen, taken from the front and each side in plain light. If you would rather not send these before speaking to someone, say so; the team can ask whether reports are enough for a first opinion.

For reconstruction after injury, surgery or a wound

• Photos of the defect or wound from several directions, ideally with a ruler in the frame for scale.
• The history: what happened, when, what has already been done, and any infection or bone involvement.
• Recent X-ray or scan reports and any wound-care notes.

For nose surgery or a cosmetic procedure

• For the nose: unfiltered, make-up-free photos showing the nose head-on, side-on from left and right, and from beneath the tip, in soft even light, plus any history of breathing trouble, nasal injury or previous nose operations.
• For other areas: photos of the area as it is now and a short note on what you would like to change.

Attach everything to your request. Whatever the records show, Dr. Suphalerk would settle on a plan only after examining you in person at Bumrungrad.
