Dr. Wanchalerm Chungsiriwattana

Dr. Wanchalerm Chungsiriwattana, M.D. (Thai: นพ. วันเฉลิม จงสิริวัฒนา) is a Thai plastic surgeon whose Bangkok outpatient clinic is at Bumrungrad International Hospital, which lists his specialty as Plastic Cosmetic & Reconstructive Surgery and gives his clinic location in the Plastic Surgery Center. Outside Bumrungrad he appears on the doctor pages of AM International Hospital in Bang Kruai, Nonthaburi, whose profile calls him a body-shape specialist within plastic surgery (ศัลยแพทย์ตกแต่งเฉพาะทางด้านรูปร่าง), and of Amara Clinic (Amara Liposuction Center). AM International Hospital's profile uses his nickname, หมอบาส, written “Dr. Bas” in English, so you may see him under that name in Thai-language material.

What he is documented for

The procedure areas on this profile come from AM International Hospital's own service pages, where he appears inside the procedure content itself (his doctor card, a video or his own commentary), not only in a page footer:

• Breast augmentation, in the part of AM's page on “hybrid” augmentation, which combines a silicone implant with fat grafting
• Breast lift, where he explains the operation in his own segment
• Gynecomastia surgery, where he discusses when surgery for enlarged male breasts is needed
• Liposuction, where he is one of five surgeons shown on the hospital's liposuction page

Bumrungrad's profile of him gives his qualifications, languages and clinic time but names no individual procedures. The hospital's Plastic (Cosmetic) Surgery Center does list breast augmentation, breast lift, gynecomastia and liposuction among the operations the centre offers. That is a department listing: it tells you these operations are available at Bumrungrad, not which surgeon performs each one.

At a glance

• Specialty: plastic surgery; Thai Board of Plastic Surgery, 2022 (per Bumrungrad)
• Medical degree: Prince of Songkla University, 2012
• Society: ThPRS member; we found his entry ourselves in the society's online directory
• Languages: Thai and English (per Bumrungrad)
• Where: Bangkok (more surgeons and hospitals in Bangkok), with a second hospital listing in neighbouring Nonthaburi

To see him, request a consultation with Dr. Wanchalerm through our patient team. We check his availability with the hospital before anything is confirmed.

The published record of Dr. Wanchalerm's training runs through two Thai university medical schools: Prince of Songkla University in Songkhla province, in the south of the country, and Siriraj Hospital, Mahidol University, in Bangkok.

• Doctor of Medicine (แพทยศาสตรบัณฑิต), 2012. Faculty of Medicine, Prince of Songkla University. Bumrungrad gives the year as 2012 on its English page and as 2555, the same year in the Thai calendar, on its Thai page.
• Internship. Faculty of Medicine, Prince of Songkla University, according to his AM International Hospital profile, which gives no year.
• Thai Board of Surgery. Listed on the AM profile with Prince of Songkla University as the training institution, again without a year.
• Thai Board of Plastic Surgery, 2022. Bumrungrad's Thai page shows his plastic surgery board certificate (Thai: วุฒิบัตร) under the year 2565, which is 2022. According to the AM profile, he did this board training at Mahidol University's Siriraj Hospital medical faculty.

Two further sources fit that sequence. Amara Clinic's page lists his specialties certified by the Medical Council of Thailand as surgery (ศัลยศาสตร์) and plastic surgery (ศัลยศาสตร์ตกแต่ง). And one of his papers on PubMed, published in 2023, gives his affiliation as the Division of Plastic Surgery, Siriraj Hospital, Mahidol University.

Post-nominals and licence

The English part of the AM profile writes his name as “Wanchalerm Chungsiriwattana, M.D., FRCST.” FRCST denotes a Fellow of Thailand's Royal College of Surgeons, a title that we have not matched against any college member list, so it is recorded here as the hospital states it rather than independently confirmed.

AM International Hospital and Amara Clinic both display Thai medical licence number 44595 on his profiles. 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. Anyone can search the register by a doctor's name, and it is sensible to do so before you commit to treatment.

What is not published

None of the profiles we read mentions training abroad, a cosmetic surgery fellowship, the year he entered private practice or the number of operations he has performed. If any of these matters to your decision, ask about it directly at the consultation; we do not fill such gaps with estimates. Our research methodology explains which sources we accept and how each fact on this page is labelled.

Bumrungrad International Hospital, Bangkok (current). The hospital lists him under Plastic Cosmetic & Reconstructive Surgery, with clinic sessions at its Plastic Surgery Center in Building A (16A). Its online schedule, as we read it on 27 September 2026, gave him one outpatient session, on Monday from 13:00 to 16:00. Clinic days can move, so our patient team rechecks the day and time with Bumrungrad whenever a request comes in.

AM International Hospital, Bang Kruai, Nonthaburi (current). Listed with the Thai title for a plastic surgeon focused on body shape. The hospital's website gives its address as 789 Moo 1, Bang Khun Kong, Bang Kruai, Nonthaburi 11130. Its breast augmentation, breast lift, gynecomastia and liposuction pages feature him, and those pages are the source of the procedure areas on this profile. AM International Hospital does not yet have its own facility profile on our site.

Amara Clinic (Amara Liposuction Center) (current). Listed as a plastic surgeon (ศัลยแพทย์ตกแต่ง) on the clinic's doctor page, which also shows his licence number. The clinic's service menu covers the clinic as a whole and does not name him, so no procedure on this profile rests on the Amara listing. The Amara and AM websites look connected, but no page we read states a relationship between the two, so we do not describe one.

Prince of Songkla University, Songkhla (dates not published). The AM profile lists him as a lecturer in two units of the university's Faculty of Medicine at Songklanagarind Hospital: the Department of Surgery and its Division of Plastic and Reconstructive Surgery. His ThPRS directory entry, posted in February 2024, gives Songklanagarind Hospital as his address, and his PubMed papers up to 2024 carry Prince of Songkla University affiliations. We could not find a current university staff page for him, so we cannot say whether the teaching role continues.

Published research

PubMed lists four papers with Dr. Wanchalerm among the authors. They come from university hospital surgery and reconstruction rather than cosmetic surgery:

• A 2024 case report in JPRAS Open on the surgical management of a patient with severe, complex injuries to the face and jaws after a bear attack in a forest.
• A 2023 case report and literature review in The American Journal of Case Reports on the successful replantation (surgical reattachment) of a child's penis after amputation during ritual circumcision.
• A 2023 paper in the Asian Journal of Surgery on immediate lymphaticovenous anastomosis in the groin after lymph node removal for skin cancer of the lower limbs. Lymphaticovenous anastomosis joins lymphatic channels to small veins.
• A 2019 paper in Surgical Infections reporting a decreasing trend in surgical site infections at a Thai university hospital after an active surveillance programme.

Replantation and lymphaticovenous anastomosis are microsurgical techniques, so the papers reflect the reconstructive and teaching-hospital setting in which he trained and taught. They are not studies of cosmetic results and do not tell you how a breast operation or liposuction with him would turn out; that is a question for the consultation.

Each area below starts with what the official source shows about Dr. Wanchalerm, followed by general information from our procedure guides. The general parts describe how these operations usually work; your own plan, and whether surgery suits you at all, is decided by him after examining you.

Breast augmentation, including hybrid implant and fat augmentation

On AM International Hospital's breast augmentation page, a video featuring Dr. Wanchalerm, together with his doctor card, sits in the section on hybrid augmentation (เสริมหน้าอกแบบ Hybrid), meaning a silicone implant combined with fat grafting.

In general, augmentation adds volume using an implant, the patient's own fat, or a mix of the two. Most implants used are filled with silicone gel; they differ in shape (round or anatomical) and surface (smooth or textured). The pocket for the implant is made either on top of the chest muscle (subglandular) or with the muscle partly covering it (dual plane), and the implant usually goes in through one of three cuts: in the under-breast crease, at the areola's lower margin, or under the arm. Fat transfer harvests fat by liposuction, and because some of the grafted fat does not survive, the gain in size is usually more modest. A hybrid plan tries to pair the two, which also means healing a liposuction donor site. Our fat transfer breast augmentation page describes the fat-only option.

Most people have a general anaesthetic and leave hospital the same day or the next; for this operation, our augmentation page advises allowing about 7–10 days in Thailand. Implants add size but do not lift a low-sitting nipple, and when droop is the main concern a lift may be suggested alongside augmentation or in its place. Possible complications described in our guide include bleeding, infection, altered nipple sensation, capsular contracture (scar tissue tightening around the implant), rupture and the need for further surgery, and implants are not lifetime devices. Ask Dr. Wanchalerm which implant brand and surface he uses at the hospital where you would have surgery, and do not leave without the implant card listing the device's brand, size and lot number. Whether augmentation, and which kind, suits your chest can only be settled by an in-person assessment.

Breast lift

AM International Hospital's breast lift page carries Dr. Wanchalerm's doctor card and a segment in which he talks patients through breast lift surgery.

In general, a lift (mastopexy) takes away stretched skin and raises the nipple and areola while reshaping the breast, without adding much volume on its own. The scar grows with the degree of droop: a circular scar confined to the areola border for mild drooping, a “lollipop” scar that runs down to the crease for moderate drooping, and an anchor (inverted-T) pattern when the sagging is greater. Putting an implant in during the same lift is a bigger undertaking, and our breast lift guide notes that the pairing carries a higher revision rate than either procedure done by itself; for that reason some surgeons split it into two stages. International patients commonly plan 10–14 days in Thailand, wear a support bra for several weeks, and can expect scars to fade over 12–18 months. Risks include wound-healing problems where scars meet, changes in nipple sensation, asymmetry and, rarely, loss of blood supply to the nipple, and sagging can return with time. If you are thinking about a lift together with the hybrid technique, ask him whether he would plan them as a single operation or stage them, and how each option changes the length of your trip.

Gynecomastia surgery (male chest reduction)

On AM International Hospital's gynecomastia page, Dr. Wanchalerm's doctor card appears alongside a segment in which he discusses whether surgery for enlarged male breasts is necessary.

In general, gynecomastia is enlargement of the breast gland in men; excess fat without an enlarged gland is called pseudogynecomastia. Because medicines, anabolic steroids, hormonal changes and some medical conditions can cause it, a doctor should check for a treatable cause first. Mainly fatty chests may be treated with liposuction alone, firm glandular tissue is removed through a small incision at the lower edge of the areola, and many patients have both; skin removal is sometimes needed after major weight loss. It is usually a day case under general anaesthesia or local anaesthesia with sedation, followed by a compression vest for several weeks and a return to chest exercise after about 4–6 weeks. International patients commonly plan 7–10 days in Thailand. Possible problems include bleeding, fluid collection, infection, asymmetry, contour irregularities and recurrence if the underlying cause continues. As he is also documented for liposuction, ask how he would balance fat removal and gland excision in your chest, and how he avoids removing too much tissue, which can leave a hollow “saucer” contour.

Liposuction

Dr. Wanchalerm is one of five surgeons shown on AM International Hospital's liposuction page, and the hospital's Thai title for him, which refers to body-shape surgery, points to the same field.

In general, liposuction takes fat from chosen areas to change body contour. Liposuction changes shape rather than body weight, and loose skin and cellulite are outside what it treats; the people our liposuction guide sees as typical candidates are close to a steady weight and have fat pockets that diet and exercise have not shifted. Common areas include the abdomen and flanks, the back and bra line, the thighs, the upper arms, and the chin and neck. Most modern liposuction is tumescent; ultrasound-assisted (for example VASER), power-assisted and high-definition techniques are variations on it, and the surgeon's judgement matters more than the device. Each surgeon caps the fat volume taken in a single session at a level they judge safe for your weight and health, and fluid shifts, bleeding and blood clots become more likely as volumes grow or procedures are combined. Expect to wear compression for several weeks; international patients commonly plan 7–10 days in Thailand (longer after large or combined procedures), and the final contour tends to show only after 3–6 months, once swelling has settled.

One point to be clear about: AM International Hospital's VASER liposuction article names Dr. Wanchalerm as its medical reviewer. Reviewing a page's content is not a statement that he performs VASER, so this profile lists liposuction in general. If you want a particular technique, ask him which one he uses and why it would suit your areas.

Procedures not on this profile

Tummy tuck and a waist-shaping operation AM calls “Corset Waist” appear alongside his name only in patient-review pages and social media posts, which we do not treat as evidence of the procedures a surgeon performs, so neither is listed here. We found nothing linking him to facial surgery. If you hope to combine liposuction with another operation, let our patient team raise it with the hospital before your travel plans depend on it.

Because Dr. Wanchalerm is listed at more than one hospital, the first thing to settle is where your operation would take place. The hospital determines the operating theatre, the nursing and inpatient care, how the price is built up and which international patient services you can use, so the choice shapes your whole trip.

Questions for any of his procedures

• At which hospital would you operate on me, and who gives the anaesthetic?
• What would the plan be for my body specifically, and what result is realistic?
• What are the main risks for me, given my health, and how would a complication be handled?
• How long would I stay in hospital, and when would you check me before I fly home?
• If a problem shows up after I fly home, who do I contact, and if a second operation were ever needed, who would carry it out and who would pay for it?
• Can I have a written, itemised quote that shows what is and is not included?

If you are considering breast augmentation

• Would an implant alone, fat alone or the hybrid approach suit my chest and my goals?
• If fat is used, where would it be taken from, and how much of it is likely to be reabsorbed?
• Which implant brand, shape, surface and size do you recommend, and would you place it above or below the chest muscle?
• Which incision would you use, and where would the scar be?

If you are considering a breast lift

• Which scar pattern do I need, and why?
• Would you add an implant or fat, and in one stage or two?
• How might the operation affect nipple sensation and future breastfeeding?

If you are considering gynecomastia surgery

• Is my enlargement mainly gland, fat or both?
• Should I have any tests for an underlying cause first?
• Would I need skin removal, and where would the scars be?

If you are considering liposuction

• Which areas would you treat in one session, and what is the safe limit for me?
• Which technique do you use, and why for my areas?
• How long should I wear the compression garment, and what do you advise on clot prevention for the flight home?

An online consultation is useful for a first discussion, and Bumrungrad's Plastic Surgery Center lists tele-consultation with a doctor among its services. Your final plan should still come from an in-person examination, and nothing said in a pre-travel discussion obliges you to go ahead.

At Bumrungrad International Hospital

Dr. Wanchalerm's Bangkok clinic is held at Bumrungrad International Hospital, a private hospital listed at 33 Sukhumvit 3 in Wattana district, on the lane locals know as Soi Nana Nua. Dr. Wanchalerm's clinic sessions take place in its Plastic (Cosmetic) Surgery Center at Counter A, sixteen floors up in Building A, where doctors see patients by appointment only. Services Bumrungrad itself publishes for patients coming from abroad include:

• Bumrungrad's Medical Coordination Office, which costs nothing to use and sits on Building A's tenth floor. Its coordinating physicians and nurses can review your records, give estimated prices and set up appointments or telemedicine before you travel, then, after discharge, handle your medical report, fit-to-fly clearance and follow-up.
• An interpreter pool the hospital numbers at over 130, backed by Cultural Support Officers and Cultural Helpdesks, useful if English is not your first language.
• An airport representative in the Suvarnabhumi arrivals hall, and a no-charge shuttle van running from the airport to Bumrungrad or to hotels close by, depending on passenger numbers.
• A complimentary van service, seven days a week, connecting Bumrungrad with the Nana and Phrom Phong stations on the BTS Skytrain.
• Help extending visas, both yours and your companions', along with embassy assistance and liaison with international insurers.

Accreditation, as shown in the accreditors' own databases in September 2026: Joint Commission International (JCI) listed Bumrungrad's hospital programme as accredited, and HA Thailand showed its Advanced Hospital Accreditation as valid until 22 May 2029.

At AM International Hospital and Amara Clinic

AM International Hospital is in Bang Kruai district, Nonthaburi, the province bordering Bangkok, rather than in central Bangkok. We have not yet researched its services for international patients, or those of Amara Clinic, so we cannot list them here. Should either location be more convenient for you, note it when you contact us; we will then put questions about language support, transfers and aftercare to the provider directly.

Length of your trip

For international patients, the general time frames on our procedure pages are roughly 7–10 days for breast augmentation, gynecomastia surgery or liposuction, and roughly 10–14 days for a breast lift, longer when operations are combined. Dr. Wanchalerm decides when you are fit to fly. On the journey home, wear your support bra or compression garment as instructed, keep moving, drink enough water, avoid lifting heavy bags and ask him about clot prevention. Carry copies of your operation notes and, after breast augmentation, your implant card. His listed languages are Thai and English; if you need another language at Bumrungrad, ask for an interpreter when we arrange the appointment.

Dr. Wanchalerm's team can decide more quickly whether to begin with an online discussion or an examination if your first message covers the basics below.
