Asst. Prof. Dr. Kachin Wattanawong

Asst. Prof. Dr. Kachin Wattanawong (Thai: คชินท์ วัฒนะวงษ์) is a Bangkok plastic surgeon whose published training ends in a craniofacial fellowship and whose posts are split between private hospitals and a university hospital. In plastic surgery he is Thai Board-certified, a qualification that the Medical Council of Thailand awards. Official pages show him on current staff in three places. His private-hospital work is split between Bumrungrad International Hospital, whose Plastic Surgery Center lists him, and Bangkok Hospital Headquarters, where he belongs to the Plastic Surgery and Reconstruction Center. His academic post is at Ramathibodi Hospital, whose Department of Surgery staff page gives him the title Assistant Professor (ผศ.) and counts him among the faculty physicians of its plastic and maxillofacial division.

Bumrungrad's profile of him carries a 'Special Clinical Interests' list of ten items, and that list is the whole basis for the procedures we connect to his name. Five of the ten match cosmetic guides on this site: eyelid surgery, facelift, neck lift, rhinoplasty and abdominoplasty, which most patients know as a tummy tuck. The remaining five lean towards reconstruction and the facial skeleton: ear surgery, facial bone contouring, orthognathic (corrective jaw) surgery, hand surgery and microsurgery, and head and neck cancer. That second group sits close to the craniofacial surgery fellowship he completed at Chang Gung University in Taiwan in 2006.

Membership and languages. A public directory entry for him, under both his Thai and English names, is kept by ThPRS, whose full name is the Society of Plastic and Reconstructive Surgeons of Thailand; it lists Bangkok Hospital, Bumrungrad and Ramathibodi as his addresses. His Bumrungrad profile records two languages, Thai and English. If you would like to see him, request a consultation: our patient team forwards it to whichever of his three hospitals suits you, then reports back on what that hospital can arrange. The request turns into an appointment only after the hospital itself confirms it.

Recognising him on Thai sources. Bumrungrad writes his name 'Kachin Wattanawong, M.D.', while Bangkok Hospital uses 'Dr. Kachin Wattanawong'; the Thai pages of both hospitals give นพ. คชินท์ วัฒนะวงษ์. Ramathibodi's pages add the academic title ผศ. (Assistant Professor) and the abbreviation ร.อ., a Thai military rank; the pages do not say which branch of the armed forces it belongs to, so we do not translate it. He should not be confused with Assoc. Prof. Thanet Wattanawong, a spine surgeon at Bumrungrad with the same surname.

Taken together, the education entries published by Bumrungrad, Bangkok Hospital and Ramathibodi trace a path from medical school through general surgery and plastic surgery to a craniofacial fellowship abroad:

• 1992, medical degree: an M.D. from Siriraj, which Bumrungrad records as the Faculty of Medicine Siriraj Hospital at Mahidol University.
• 1997, surgery: Bangkok Hospital's education list shows surgery at Phramongkutklao College of Medicine in 1997, the same year Bumrungrad gives for his Diploma of the Thai Board of Surgery. Ramathibodi's Department of Surgery staff page identifies the Medical Council of Thailand as the body that issued it.
• 1999, plastic surgery: Bangkok Hospital lists plastic surgery at Ramathibodi Hospital, Mahidol University in 1999, matching the year Bumrungrad gives for his Diploma of the Thai Board of Plastic Surgery, again issued by the Medical Council of Thailand.
• 2006, craniofacial fellowship: Bumrungrad places his craniofacial surgery fellowship at Chang Gung University, Taiwan; on Ramathibodi's staff list the same training appears as a 'Certificate of Clinical Fellowship in Craniomaxillofacial Surgery, Taiwan'.
• Special clinical training: Bumrungrad lists cranio-maxillofacial surgery as a separate entry.

Two limits apply to this list. Bangkok Hospital shows the Phramongkutklao and Ramathibodi entries only as a year and a field, so we do not call them residencies. And none of the sources gives the length of the Taiwan fellowship.

Reading these qualifications as a patient. In general, two checks are worth making before any operation in Thailand: that the surgeon is licensed by the Medical Council of Thailand, and that they hold specialist training in the relevant field. For plastic surgery, that specialist qualification is the Thai Board diploma issued by the Medical Council, which Dr. Kachin's profiles date to 1999. His later fellowship was in craniofacial (craniomaxillofacial) surgery, the branch of plastic surgery that works on the skull, facial skeleton and jaws together with the soft tissue covering them. For a patient, that background matters most when a concern lies in the bony framework of the face rather than in skin or fat alone. What it cannot tell you is how many eyelid, facelift, nose or tummy tuck operations he performs in a typical year; that question is for him to answer.

Licence check. The licence number printed on his ThPRS member entry is 17552. 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. The register is public and its name search is open to anyone; our research methodology sets out the checks we run on each surgeon and how we record a source we were unable to open.

The three posts below were each shown as current on the official page we read on 27 September 2026. No page gives a starting year for any of them, and the 'Medical Experience' tab of his Bumrungrad profile is blank, so this profile gives no figure for how long he has been in practice.

• Bumrungrad International Hospital. A Plastic Surgery Center surgeon, listed under the hospital's specialty heading 'Plastic Cosmetic & Reconstructive Surgery', with his clinic given as Building A, 16A. According to the profile he holds outpatient sessions on Tuesday and Thursday from 17:00 to 20:00 and on Sunday from 08:00 to 15:00.
• Bangkok Hospital Headquarters. He is listed as a plastic surgeon of its Plastic Surgery and Reconstruction Center; the profile's specialty fields read 'Plastic Surgery' and 'Surgery'. The page we read shows no clinic hours.
• Ramathibodi Hospital, Department of Surgery (Faculty of Medicine, Mahidol University). Assistant Professor (ผศ.) and faculty physician (อาจารย์แพทย์) in the plastic and maxillofacial surgery division. Bangkok Hospital's education list also names Ramathibodi for his 1999 plastic surgery training.

His ThPRS directory entry gives addresses at Bangkok Hospital, Bumrungrad and Ramathibodi, which agrees with the three hospital pages. Timetables tend to change faster than web profiles are updated, which is why we reconfirm his sessions for every new request.

Published research. A PubMed author search returns three papers that belong to him. All three deal with cleft and craniofacial questions rather than cosmetic surgery:

• 2007, Chang Gung Medical Journal: a comparison of outcomes between inferiorly and superiorly based pharyngeal flaps in velopharyngeal surgery, which helps the soft palate seal off the nose during speech. He is first author, with a Chang Gung affiliation.
• 2011, Journal of Oral and Maxillofacial Surgery: considerations for orthognathic surgery in patients with undiagnosed type I osteogenesis imperfecta, a condition that makes bones fragile.
• 2016, Birth Defects Research Part A: a systematic review and meta-analysis of IRF6 and 8q24 gene variants in cleft lip with or without cleft palate, with his affiliation given as Ramathibodi.

These papers show academic work in his craniofacial field. They say nothing about results in the cosmetic operations covered on this page, and we do not use them as evidence of that.

Every procedure in this section traces back to one place: the 'Special Clinical Interests' list on his Bumrungrad profile. Each entry there is a short label with no detail on technique, volume or outcomes, and neither the Bangkok Hospital nor the Ramathibodi page expands on them. Each area below therefore starts with what the label does and does not establish about Dr. Kachin, followed by general points from our procedure guides that apply to anyone considering the operation. Suitability for any of these operations is a judgement Dr. Kachin makes in person, after assessing you.

Eyelid surgery (blepharoplasty). On his list as 'Eyelid Surgery'. Unstated: whether he treats upper eyelids, lower eyelids, creates creases through double eyelid surgery, or all of these. General guidance: an upper-lid operation trims the skin, and sometimes fat, that folds down over the lid; a lower-lid operation deals with puffiness beneath the eyes by removing or redistributing fat; a double eyelid procedure forms a new crease. A lid edge that sits too low over the eye is ptosis, which involves the lifting muscle and is treated by ptosis correction, while heaviness that actually stems from a lowered brow is sometimes better handled by a brow lift. Only an examination separates these. Our eyelid guide lists local anaesthetic with sedation (a general anaesthetic is the alternative) and, for most patients, going home the same day. Visitors from abroad usually build their stay in Thailand around stitch removal, which falls at roughly 5–7 days. Conditions such as dry eye, glaucoma and thyroid eye disease change what is safe, so be ready to discuss your eye health and eyesight in detail.

Facelift. On his list as 'Face Lift'. Unstated: his technique, whether a classic SMAS lift, a deep plane facelift or a mini facelift. General guidance: the operation lifts the deeper layer beneath the skin of the jowls, jawline and upper neck, then removes the skin left over. The brow, the eyelids and fine skin texture stay as they were, so those need separate treatment if they concern you. Our facelift guide mentions general anaesthesia or IV sedation and a hospital stay that is usually 1–2 nights; overseas visitors commonly spend 10–14 days in the country before flying home. Bleeding that collects under the skin (a haematoma) is the serious complication the guide names as most frequent, and it can require drainage; other risks include infection, usually temporary facial nerve weakness and numbness. Smokers face a higher chance of skin-healing trouble, so nicotine should be stopped well ahead of the operation.

Neck lift. On his list as 'Neck lifts'. General guidance: a neck lift addresses loose skin under the chin and the vertical cords formed by the platysma muscle, and surgeons frequently perform it together with a facelift. Whether your neck needs its own procedure, or will improve enough with a facelift, depends on where the looseness lies, and that is decided at examination. For planning, our neck lift page suggests budgeting 10–14 days in Thailand. Each procedure added to a plan tends to lengthen both the operation and the recovery, so ask how a combined plan would affect your time in Bangkok.

Rhinoplasty. On his list as 'Rhinoplasty'. Unstated: whether his nose work is mostly reduction, augmentation (commonly called Asian rhinoplasty), revision rhinoplasty or functional septorhinoplasty. General guidance: rhinoplasty alters the nasal bones and cartilage, often improving breathing at the same time. To raise a flat bridge or project a tip, surgeons either borrow cartilage from elsewhere in the patient's body (septum, ear or rib) or place a synthetic implant, usually silicone or ePTFE; the choice trades off infection risk, how the nose feels to the touch, and how the result holds over the years. Our rhinoplasty guide notes that general anaesthesia is usual and that an external splint protects the nose at first; visitors commonly stay 7–10 days so that the splint can be removed and the nose checked before they fly. Swelling at the tip fades slowly, over 12 months or longer, so the shape seen in the first weeks is not the end result.

Tummy tuck (abdominoplasty). On his list as 'Abdominoplasty'. Unstated: which variants he performs, such as a mini tummy tuck, a full abdominoplasty or an extended tummy tuck, and whether he adds liposuction. General guidance: the operation takes away lax skin and fat from the lower abdomen, usually repositions the navel, and, in most full operations, stitches together the separated rectus muscles (diastasis recti), a common change after pregnancy. It is not a substitute for losing weight. Surgeons generally prefer to operate after several months at a settled weight, and after any planned pregnancies. Our guide's figures: a general anaesthetic, a hospital stay commonly of 1–3 nights, temporary drains, and 12–14 days in Thailand for overseas patients. The same guide warns that clot risk after abdominoplasty ranks among the higher ones in cosmetic surgery; with a long-haul flight ahead, ask for a concrete prevention plan.

The other five interests. Ear surgery, facial bone contouring, orthognathic surgery, hand surgery and microsurgery, and head and neck cancer also appear on the Bumrungrad list, but we deliberately stop short of linking them to procedure pages. 'Ear Surgery' could mean cosmetic reshaping of prominent ears (otoplasty) or ear reconstruction, and the label does not say which; Bumrungrad's Plastic Surgery Center does list otoplasty among its services, but that describes the centre, not him. 'Facial Bone Contouring' names no bones or operations, so it cannot be matched to jaw contouring or V-line surgery. Jaw correction, hand surgery and microsurgery, and cancer reconstruction have no guides on this site. If one of them is your reason for contacting Dr. Kachin, put it at the top of your message; we then ask the hospital to confirm it before discussing anything else.

Because Dr. Kachin's profiles stop at short procedure labels, the consultation is where you learn how he would approach your own case. The questions below aim at what the public record leaves out. As a general rule, any plan built only from photographs stays provisional until he has examined you.

Whatever the procedure - Of Bumrungrad, Bangkok Hospital and Ramathibodi, where would you operate on me, and would my follow-up visits be in the same place? - Will an anaesthesiologist manage my anaesthetic, and would you choose general anaesthesia or sedation in my case? - In a typical year, how many patients do you treat with this operation, and could I see photographs of patients who started from a similar point? - Which items does the written estimate cover, and who pays for extra nights, further treatment or a revision if one turns out to be needed? - On which day are you likely to clear me for the flight, and who looks after me once I have gone home?

Eyelids - Is the heaviness I see caused by skin, fat, the position of my brow or a drooping lid (ptosis)? - Do my upper lids need surgery, my lower lids, or both? Below the eye, would you go through the skin just under the lashes or through the inner lining of the lid? - If I want a double eyelid crease, do you prefer an incision or a stitch (non-incisional) technique for lids like mine, and how long might each result last?

Face and neck - Which facelift method do you use, and what makes it suit my face? - Can a facelift alone improve my neck, or do I need a separate neck lift? - If eyelid surgery or a brow lift were added in the same session, how much longer would the operation and my stay become? - Where will the incisions sit, and what do you do to lower the chance of a haematoma?

Nose - Does my nose need reduction, augmentation or a mix of both? - If my bridge or tip needs building up, would you use rib, ear or septal cartilage, or silicone or ePTFE, and how do those options compare in my case? - Do you plan an open (external incision) or closed technique for me, and will my nasal airway be assessed alongside the shape? - For a secondary (revision) case like mine, what can realistically still be changed, and how long should the tissues settle first?

Abdomen - Which type of tummy tuck fits my skin and muscles: a mini, a full or an extended operation? - Will you tighten the separated muscles, and would liposuction of my flanks or waist be part of the plan? - How will you reduce my blood-clot risk in hospital and on the flight home?

Jaw and facial bones. Given his craniofacial fellowship and the 'facial bone contouring' and 'orthognathic surgery' entries on his profile, patients with a jaw or chin concern may want to ask what those labels cover in his practice, which scans he would need, and whether another specialist, such as an orthodontist, would take part. The profile itself answers none of this, so the answer has to come from him.

How much we can tell you about overseas-patient support differs sharply between Dr. Kachin's three hospitals, and that may influence where you choose to see him.

Of the three, we hold the fullest record for Bumrungrad International Hospital, at number 33 on Sukhumvit 3, a lane also called Soi Nana Nua, in Watthana. Its Medical Coordination Office, a free service for international patients, sits on level 10 of Building A. Before you travel, its coordinating doctors and nurses can review your records, give price estimates, set up appointments and arrange telemedicine; after discharge they prepare your medical report and a fit-to-fly letter, and help organise follow-up. Bumrungrad's factsheet counts over 130 interpreters, and for patients who would rather not consult in English it also has cultural support officers, useful to know since Dr. Kachin's own listed languages are Thai and English. The hospital also publishes an airport representative desk in the Suvarnabhumi arrivals hall, a free airport van that leaves hourly when passenger numbers allow, complimentary vans to and from two Skytrain stops, BTS Nana and BTS Phrom Phong, help with visa extensions, and hotel booking through its Business Center. The plastic surgery unit itself, at Counter A on level 16 of Building A, sees patients for doctor consultations only by appointment and can also arrange a tele-consultation. Its accreditations include JCI and, from HA Thailand, an Advanced Hospital Accreditation that the accreditor shows as expiring on 22 May 2029; the accreditor records sit on our Bumrungrad profile.

Bangkok Hospital Headquarters is recorded on our site as having an international patient desk. Beyond that desk, we hold no detail about its overseas-patient services, so check its profile and ask our patient team what the hospital provides when you request dates there.

Ramathibodi Hospital is part of Mahidol University through its Faculty of Medicine Ramathibodi Hospital, and the plastic and maxillofacial division where Dr. Kachin holds his academic post offers cosmetic as well as reconstructive surgery. Our records contain nothing yet on services there for patients travelling from abroad; its profile shows what we do hold, and our team can look into practical arrangements for anyone who wants their care at the university hospital.

Planning the length of your trip. Across his five listed procedures, the typical time overseas patients spend in Thailand, taken from our procedure guides as general guidance, is: tummy tuck 12–14 days, facelift and neck lift 10–14 days, rhinoplasty 7–10 days, eyelid surgery 5–7 days. Combining procedures usually adds time. Treat these as planning ranges, not a schedule set by Dr. Kachin: only he can clear you to fly. A changeable return ticket helps, and so does accommodation close to the hospital that will treat you. Before surgery, settle how aftercare continues once you are back home and whom you should contact if something goes wrong. His listed Bumrungrad clinic times, Tuesday and Thursday evenings plus Sunday, are also worth factoring into your arrival date.

Including the right details in your first message lets Dr. Kachin's team decide whether they can give an initial view remotely and what has to wait for an in-person visit. Please use only our booking form or this site's WhatsApp number for photos and medical information, and keep photos back until his team specifically asks.

Useful in every request - what you want to change, or the problem you want assessed - which of his hospitals you would prefer, your travel window, and whether you want to start online or in person - medical conditions, regular medicines and supplements (especially any that affect bleeding), allergies, plus any cigarettes, vapes or other nicotine products you use - any surgery you have already had, above all in the same region, plus the surgeon's report where you have it - anything you already know you want Dr. Kachin to explain

Eyelids - whether you have been diagnosed with glaucoma, thyroid eye disease or dry eye, any change in your vision, and your latest eye test result if available - if his team asks for photos: straight-on shots in soft, even light (eyes open, eyes lightly shut, gaze raised) and both profiles

Facelift or neck lift - earlier facial surgery or non-surgical treatments such as fillers, with approximate dates - if photos are requested: five angles (front, each profile, each three-quarter view), with hair off the face and chin level so the jaw and neck show clearly

Rhinoplasty - previous nasal surgery or injuries, breathing difficulty and allergies; for a revision, your earlier surgeon's operation notes if you can get them - when his team wants photos: the nose from the front, from the side and from underneath, in neutral light

Tummy tuck - your pregnancies, whether more are planned, and how your weight has changed recently - previous abdominal surgery such as a caesarean section, and any past blood clots - if photos are requested: standing photos of the abdomen from the front and each side

Jaw, facial bone or ear concerns - existing scans, X-rays or specialist letters, and a short note on what you want addressed

A first request does not need to be complete. After the hospital has reviewed it, our team will pass on exactly what Dr. Kachin's team needs from you.
