Asst. Prof. Dr. Jiraroch Meevassana

Asst. Prof. Dr. Jiraroch Meevassana (Thai: จิระโรจน์ มีวาสนา; title ผศ.ดร.นพ.) combines an academic post at Chulalongkorn University with places on the medical teams of two private plastic surgery facilities in Bangkok. Chulalongkorn's Department of Surgery, part of the Faculty of Medicine, files his profile in หน่วยศัลยศาสตร์ตกแต่งและเสริมสร้าง, its unit for plastic and reconstructive surgery, gives his rank as Assistant Professor and names one area of special expertise, the same field. The unit forms part of the surgical service at King Chulalongkorn Memorial Hospital in Pathumwan, which the Thai Red Cross Society runs as a university teaching hospital, and that is where his weekly outpatient session is published.

Two private facilities also name him:

• W Plastic Surgery Hospital in Lat Phrao, a hospital dedicated to plastic surgery, includes Dr. Jiraroch in its doctor team under the Thai label ศัลยแพทย์ตกแต่งและเสริมสร้าง (plastic and reconstructive surgeon).
• The SiB Plastic Surgery, a clinic on Rama 9 Road in Huai Khwang, gives him a profile page as a plastic surgeon on its medical team.

Much of his published record is academic. A Faculty of Medicine staff page from February 2026 adds a second Assistant Professor post, in the Department of Anatomy, and CUPS, the website of the university's plastic surgery division, names him Program Director of a Ph.D. programme in Biomedical Sciences and Biotechnology that Chulalongkorn runs as a double degree with the University of Liverpool. ThPRS, Thailand's professional society of plastic and reconstructive surgeons, also includes him on its public member list.

Anyone weighing a cosmetic operation with him should know about one gap from the outset: the official pages we read do not say which cosmetic procedures Dr. Jiraroch performs. They document his specialty, a long list of courses, volunteer reconstructive surgery, a scar and wound care fellowship, and research on keloids, burns, breast volume and the cartilage of the nasal septum. If there is a specific operation you are hoping for, request a consultation with Dr. Jiraroch; our patient team first asks the facility whether he would take on that operation, and only then arranges anything. For the checks behind every statement here, and when they were made, see our provider research methodology.

Medicine and early surgical years. According to CUPS, Dr. Jiraroch read medicine at Chulalongkorn's Faculty of Medicine between March 1998 and May 2004, graduating as Doctor of Medicine (แพทยศาสตรบัณฑิต); that page writes the degree as 'M.D., M.Sc' without saying what the M.Sc covered. The next entries are a general surgery intern programme at Nakornratchasima hospital (June 2004 to June 2007) and two certificates from the Thai Society of General Surgery: a Diploma of Clinical Science (2005–2006) and a Diploma Basic Science of Surgery (2007–2008).

Specialist training in plastic surgery. He trained as a plastic surgery resident within Chulalongkorn's own Division of Plastic and Reconstructive Surgery. CUPS gives June 2008 to June 2012 and titles the entry 'Board Certified Plastic and Reconstructive Surgery'; the Department of Surgery profile places the residency at 2007 instead, so the start year differs between the two university sites. The Department of Surgery profile also lists his specialist diploma for plastic and reconstructive surgery (Thai: วุฒิบัตร), which the Medical Council of Thailand awards; our research record dates his to 2012. This council-issued diploma is the formal specialist qualification for plastic surgeons in Thailand.

Time abroad: Michigan and Tokyo.

• Beaumont Hospital, Michigan (United States): an observation fellowship in the integrated craniofacial and microsurgery programme of its Department of Plastic Surgery. Chulalongkorn's two sites date it 2015; W Plastic Surgery Hospital's page gives 2017.
• Nippon University, Tokyo (Japan): a research fellowship (plastic and reconstructive surgery) at Nippon's Department of Plastic Surgery, March 2016 to April 2017 according to CUPS.
• W Plastic Surgery Hospital also names him a Fellow in Scar and Wound care at Nippon University, with the year 2018. Neither page says whether this is the same Tokyo stay described in different words.

Two doctorates. Chulalongkorn's pages record a Doctor of Philosophy in Biomedical and Biotechnology from the University of Liverpool, which CUPS dates August 2017 to October 2022; W and SiB call it a Ph.D. in Biotechnology and Stem Cells. CUPS adds a Doctor of Philosophy in Bioengineering from Chulalongkorn's Faculty of Medicine, dated November 2023. These account for the 'ดร.' in his Thai title, which CUPS writes out in full as ผู้ช่วยศาสตราจารย์ ดอกเตอร์ นายแพทย์ (assistant professor, doctor of philosophy, physician).

Short courses, as published by W Plastic Surgery Hospital (several also appear on his SiB profile, sometimes under slightly different titles):

Attending a course records a subject he has studied. It is not a statement of the operations he offers, and we have not treated any of these courses as one.

University and hospital posts. On his Department of Surgery profile, Dr. Jiraroch appears at Assistant Professor rank within the plastic surgery unit, with one published outpatient session: Wednesdays from 08:00 to 14:00, on floor six of the building known as Chakri Thotsamo (ตึกจักรีทศมฯ). Plastic and reconstructive surgery is one of 10 divisions in the hospital's surgical department, and the current roster for that division lists 10 plastic surgeons. Clinic timetables at a teaching hospital can change, so treat the Wednesday session as a starting point and ask us to confirm it before you arrange travel around it.

Beyond surgery, a February 2026 staff page on the Faculty of Medicine site lists him as an Assistant Professor in the Department of Anatomy, based on the 11th floor of the Pattayapat Building; the Faculty's April 2021 page had listed him there as a Lecturer. CUPS gives him a further role as Program Director of the Ph.D. Program in Biomedical Sciences and Biotechnology, the double degree Chulalongkorn offers jointly with the University of Liverpool.

Private practice in Bangkok. W Plastic Surgery Hospital lists him on its doctor team as a plastic and reconstructive surgeon. The SiB Plastic Surgery presents him as a plastic surgeon, with the plain title 'Dr.' on its English profile rather than his academic rank. Neither facility states when he joined, how many days he works there, or which of the facility's own procedures are his.

Volunteer surgery. CUPS records that he has operated as a Thai Red Cross volunteer plastic surgeon since 2011, in rural parts of Thailand, on cleft lip, cleft palate, hand deformity and congenital hand disease. It lists a second volunteer role with Operation Smile, without dates, covering the same conditions plus burn scar contracture.

Published research. Searching PubMed for 'Meevassana J' as an author returned 21 papers, every one carrying a Chulalongkorn affiliation. Eight examples show the range: nasal septal cartilage anatomy (Aesthetic Plastic Surgery, 2021); converting breast tissue weight into volume (Gland Surgery, 2023); a cadaver study mapping lateral chest wall perforators for oncoplastic breast surgery (Journal of Plastic, Reconstructive & Aesthetic Surgery, 2025); LINE-1 and Alu methylation in keloid (Scientific Reports, 2025); Box A of HMGB1 in second-degree burn healing in rats (Burns, 2025); the 3D PED BURN app, which calculates how much of a child's body surface is burned (Health Science Reports, 2022); 5-methylcytosine staining and melanoma prognosis (Scientific Reports, 2024); and a cadaver dye study of injection patterns for masseter hypertrophy (Dermatologic Surgery, 2021). He is one of the authors on each. None of these papers reports results for his own private patients.

No official page states how long he has been in practice or how many operations he has done, and we do not supply either figure.

Most patients search by operation, but Dr. Jiraroch's official record is built around other things: a specialty, volunteer reconstructive work, a scar and wound fellowship, research topics and a list of courses. No page lists the cosmetic procedures he performs. Each part below takes one strand and says what it does, and does not, tell you.

Plastic and reconstructive surgery: his stated expertise

His Department of Surgery profile names ศัลยศาสตร์ตกแต่งและเสริมสร้าง, that is, plastic and reconstructive surgery, as his only special expertise, consistent with his Medical Council diploma. In general the specialty spans reconstruction, which restores form or function after injury, disease or a congenital difference, and cosmetic surgery on healthy tissue. When you write to him through W or SiB, make clear which kind of help you want: a reconstructive question usually needs records such as operation notes, scans or pathology results that a cosmetic enquiry does not.

Cleft, hand and burn scar surgery

Cleft lip, cleft palate, hand deformity, congenital hand disease and burn scar contracture are the conditions named in his volunteer work with the Thai Red Cross and Operation Smile. That work is described as volunteer surgery in rural Thailand, not as a paid service at W Plastic Surgery Hospital or The SiB Plastic Surgery, and our site has no guide to these operations. If you are an adult asking about a further operation after childhood cleft or hand surgery, or about a tight burn scar, set out the problem and each earlier operation in your request. Our patient team will find out whether, and where, he could assess you.

Scars, keloids and wound healing

The scar and wound care fellowship listed by W, together with his papers on keloid DNA methylation and burn wound healing, form the closest match between his training and his research. They still do not say which scar treatments he provides privately. For a scar enquiry, include clear photos taken in daylight, when and how the scar formed, and every treatment tried so far.

Nose, breast, body contour and face: courses, not a procedure list

Several of his courses sit in cosmetic territory: Periorbital Rejuvenation and Facial Reanimation (Chulalongkorn, 2015), the ASAN Medical Rhinoplasty Forum (South Korea, 2017), Breast and Body Contour Aesthetic Surgery (Oxford, 2020), Breast Cosmetic and Reconstructive Surgery (Cambridge, 2021) and Facial Contouring and Face Lift (Gangnam, Seoul, 2022). His papers on septal cartilage, breast volume and the blood supply of the lateral chest wall overlap with some of these subjects. W and SiB both list rhinoplasty, breast augmentation and facelift among their facility services. Put together, this is a reason to ask him, not proof that he performs any of those operations, and we will not link a procedure to his profile until an official page does.

If one of these is the operation you have in mind, our general guides give the background. The points below come from those guides and are general guidance, not Dr. Jiraroch's own protocol:

• Rhinoplasty. Requests divide into making the nose smaller or more refined, and adding height to a low bridge or projection to the tip with cartilage or an implant; the risks differ with the material. Because splint and stitch removal usually falls between the fifth and tenth day, the guide suggests planning roughly 7–10 days in Thailand, with a check before you fly.
• Breast augmentation. An implant is not expected to last a lifetime, and many people later need another operation to exchange or remove it. The guide also covers implant surface and BIA-ALCL, a rare lymphoma associated chiefly with textured-surface implants. Around 7–10 days in Thailand is typical, allowing a wound review before the flight home.
• Facelift. Stitches come out in stages over roughly the first week, and the guide names bleeding that pools under the skin (haematoma) as the most frequent serious complication. The guide suggests 10–14 days in Thailand before travel.

Each of these operations carries risks, and whether one suits you can only be decided after a qualified surgeon has examined you. Before booking flights, get written confirmation from the facility that Dr. Jiraroch himself would operate.

With no published procedure list, the most useful first conversation with Dr. Jiraroch is about scope, not technique. Patients commonly work through these questions, roughly in this order:

• Is this an operation he takes on, and how regularly? Ask the facility to confirm in writing that he, not a colleague, would be the operating surgeon, and roughly how many operations like yours he does in a year.
• Which of his three Bangkok settings would treat me? Pathumwan, Lat Phrao and Huai Khwang are different districts, and the place of surgery determines the price, the deposit, nursing care and follow-up. Settle this before comparing quotes.
• Who is my anaesthetist, and what is the plan if I need more care? Ask who will be responsible for your anaesthesia, and what the plan is should an extra night or a transfer become necessary.
• How do his university duties fit my dates? Alongside surgery he holds posts in two Chulalongkorn departments and directs a doctoral programme, and his published hospital session is on Wednesdays. Ask when he would examine you before surgery, who reviews you afterwards on days he is not there, and whom to contact once you are home.
• What technique and material would he choose for me, and why? For the nose, your own cartilage or an implant; for the breasts, implant type, surface and position; for a facelift, how extensive the operation would be.
• What exactly is included in the price? Request an itemised written quote covering surgeon, anaesthesia, hospital nights, pre-operative tests and follow-up, plus the policy and cost if a revision is needed.

If you are shown photos of similar cases, check that the patients were his own and that they were treated at the facility you are considering.

For a reconstructive or scar concern, also ask whether he expects a single operation or a staged plan, and how your progress would be followed once you have left Thailand.

Our procedure guides describe recovery and risk in more depth. Suitability for any operation is decided only after an in-person examination by a qualified surgeon.

Languages. None of the official pages states which languages Dr. Jiraroch speaks. At facility level, The SiB Plastic Surgery lists Thai and English, and W Plastic Surgery Hospital lists Thai. His training in Michigan, Tokyo and Liverpool is documented, but that does not confirm the language of your consultation, so ask our patient team whether to arrange an interpreter.

Where he is listed.

• W Plastic Surgery Hospital: founded in B.E. 2561 (2018) and devoted to plastic surgery; address: Soi Pradit Manutham 25, No. 1, off Pradit Manutham Road, Lat Phrao, Bangkok 10230.
• The SiB Plastic Surgery, 795 Rama 9 Road, Huai Khwang, Bangkok 10310: a clinic whose medical team is headed by plastic surgeon Dr. Darin Muangthai.
• King Chulalongkorn Memorial Hospital: opened in 1914 and run today by the Thai Red Cross Society as the teaching hospital of Chulalongkorn's medical faculty; street address 1873 Rama 4 Road, Pathumwan, Bangkok 10330.

Pick your hotel only after the operating facility is confirmed; staying close to it makes the early check-ups easier. Our Bangkok page has more on the city.

Accreditation. HA Thailand's database shows King Chulalongkorn Memorial Hospital with Advanced Hospital Accreditation on a certificate awarded on 23 May 2025, with 22 May 2029 as its expiry date. We also searched the JCI directory and found no listing for it. For W Plastic Surgery Hospital and The SiB Plastic Surgery our profiles show no accreditation yet: we record one only from an accreditor's own database or a current, dated statement by the facility. You can put the question to either facility directly.

Support for overseas patients. King Chulalongkorn Memorial Hospital's official site has English pages, but none that we found describes an international desk, interpreters or airport pick-up. Our W and SiB profiles record languages only. Before travelling, ask whichever facility will operate whether it offers airport transfers or an interpreter, and whether it will give you an English medical report for your own doctor.

Length of stay. This varies with the operation and with your healing. The typical stays in our rhinoplasty, breast augmentation and facelift guides are a starting point; buy a ticket you can change, because your surgeon, not the airline date, decides when flying is safe for you.

The first question his team has to answer is whether he can help with your concern, and at which of his three facilities. Give them enough to decide that, and send more only when they ask.

• The request itself: the operation or problem, any facility preference, the dates you could travel, and whether an online or in-person first meeting suits you.
• Health background: current conditions, past operations of any kind, all medicines and supplements (flag any blood thinners), allergies, and smoking, vaping or other nicotine use.
• Previous surgery on the same area: operation notes or discharge reports, and the brand or type of any implant or graft if known. For revision and reconstructive requests this is often the most important item.
• Scars, burns and wounds: photos in daylight, how and when the scar or wound began, and each treatment already tried.
• Earlier cleft or hand surgery: whatever records you have, and the name of the hospital that operated.
• Nose: front view, both profiles and a view from below in even light, plus any past injury, breathing difficulty or nasal surgery.
• Breast or body: clear photos only if his team asks, and the details of any implants you already have.
• Your list of questions: including those in the consultation section on this page.

Send medical information and photos through our consultation request form or the site's WhatsApp line rather than other channels. Any plan built on photos stays provisional until Dr. Jiraroch has examined you in person.
