Dr. Thawatchai Boonpadhanapong

Dr. Thawatchai Boonpadhanapong (Thai: นพ.ธวัชชัย บุญพัฒนพงศ์) is a Thai plastic surgeon who works at Yanhee International Hospital, a JCI-accredited private hospital located in Bang Phlat, Bangkok. On the hospital's English-language profile his job title reads Plastic Surgeon, with 2004 given as the start of that post; the same page lists Thai and English as his languages. The hospital's Thai-language doctor directory places him in two units: the plastic surgery centre (ศูนย์ศัลยกรรมตกแต่ง), and the revision centre for people dissatisfied with a cosmetic operation they had somewhere else.

Most of his documented work concerns the nose. His name appears on four separate Yanhee nose pages (nose reshaping, ultrasonic rhinoplasty, nose implants and rib-cartilage nose augmentation), and the treatment-experience section of his Thai profile (ประสบการณ์ในการรักษา) names both open rhinoplasty and nose augmentation with rib cartilage. Taken together, the hospital's official pages name him for these procedures:

• Rhinoplasty, including nasal bone reshaping by the ultrasonic (Piezo) technique
• Augmentation (Asian) rhinoplasty, using an implant or rib cartilage
• Facial feminization surgery
• Chin augmentation
• Breast augmentation, in the endoscopic form named on his Thai profile
• Buttock implants

Two further operations on his record have no matching procedure guide on our site. One is an endoscopic lift of the mid-face and brow, usually fixed with an Endotine device, for which Yanhee lists no surgeon other than him. The other is a buttock lift that removes loose skin rather than adding volume. Both are described in the practice-areas section below, together with the points his record leaves open.

Clinic hours on the English profile, checked by us on 27 September 2026, ran from 9:00 to 17:00, Tuesday to Saturday, with Sunday and Monday marked as days off. Schedules change, so our patient team confirms his days with Yanhee when you request a consultation with Dr. Thawatchai. Every fact about him on this page comes from a source we opened and dated: Yanhee's official profiles, professional society lists and published records. General guidance is marked as such; for our source-checking process, see the provider research methodology page.

Medical degree. Dr. Thawatchai's Doctor of Medicine (แพทยศาสตรบัณฑิต) is from Chulalongkorn University; the English profile words the institution as King Chulalongkorn Memorial Hospital. The two Yanhee profiles disagree on the year. The English page says 1984, while the Thai page gives B.E. 2535, which corresponds to 1992. We have not been able to resolve the difference from a primary source, so this page gives no graduation year. If the date matters to you, ask Yanhee, or run his name through the doctor-search tool of the Medical Council of Thailand.

Specialist training in Thailand. The later steps carry consistent dates on both profiles:

• General surgery: specialty training at Khon Kaen Hospital, which the English profile dates to 1996, and a Thai surgery diploma (วุฒิบัตร), placed by the Thai profile in B.E. 2539 (1996).
• Plastic surgery: specialty training at Chulalongkorn Hospital, dated 1998, followed by a plastic surgery diploma, which the Thai-language page places in B.E. 2541 (1998). Neither profile says which body issued the two diplomas.
• University record: CUPS, the division at Chulalongkorn where plastic surgeons train, publishes alumni pages that put him in cohort 14 (รุ่นที่ 14) and gives the plastic surgery department of Yanhee Hospital as his address. That list is held by the department that trained him, independently of the hospital's own profile.

International training. Three periods in North America appear on the English profile: the Christine M. Kleinert Institute in Louisville, Kentucky (2001), Plastic Surgery Associates in Jackson, Mississippi (2001), and the Division of Plastic Surgery at Toronto General Hospital in Ontario, Canada (2002). The profile does not say whether these were fellowships, observerships or shorter visits, or how long each one lasted, so we refer to them only as international training.

Courses and workshops. Both profiles also record continuing education, much of it linked to the procedures Yanhee names him for:

• Chang Gung Memorial Hospital, Taiwan, September 2006: an international workshop on reconstructive microsurgery that also covered cleft lip and palate and maxillofacial techniques
• UT Southwestern Medical Center, Dallas, Texas, March 2007: the 24th Annual Dallas Rhinoplasty Symposium
• April 2007: Live Surgery Course on Gluteal Implants, Bangkok
• July 2007: IMCAS Asia 2007, an international master course on ageing skin, Bangkok; in the same month, a ThPRS academic meeting
• March 2008: Live Surgery Workshop on Dissolvable Thread Lift (Happy Lift), Bangkok
• 2014 (B.E. 2557): ASEAN MENTOR CPG Live Surgery Workshop
• 2016 (B.E. 2559): OSAPS 2016 in Taipei, which the Thai profile calls the 15th international meeting of the Oriental plastic surgery society
• 2017 (B.E. 2560): Endotine Workshop
• 22 September 2019: Certificate of Completion, T&R Mesh Rhinoplasty

A course attended is not a qualification, and the profiles say nothing about what each one involved. What the list does show is where his continuing education has been directed: nose surgery (the Dallas symposium and the 2019 mesh rhinoplasty certificate), gluteal implants, and the Endotine device used in the endoscopic facial rejuvenation that Yanhee lists him for.

Yanhee International Hospital, since 2004. Dr. Thawatchai currently holds the post of Plastic Surgeon at Yanhee International Hospital, Bangkok, with a start year of 2004 on his English profile. Yanhee states that the 18 plastic surgeons on its team are board-certified and all belong to ThPRS, the national plastic surgery society; he is one of those 18 names in the hospital's English doctor directory, and the Thai directory carries him as well. The Thai directory also lists him a second time, under the unit that corrects cosmetic surgery first carried out elsewhere.

Medical reviewer of the Adam's apple page. Yanhee's English page on Adam's apple shaving (chondrolaryngoplasty), updated on 4 August 2026, names him as its medical reviewer. He is not, however, among the surgeons that page lists as performing the operation, which is why tracheal shave does not appear among his procedures here. Reviewing the medical content of a hospital web page and performing the surgery are different roles.

Rajavithi Hospital, earlier. His profile names Rajavithi Hospital in Bangkok under medical experience, without a role or dates. A 2002 report of the International Atomic Energy Agency (IAEA), *The Radiological Accident in Samut Prakarn*, includes 'Boonpadhanapong, T.' of Rajavithi Hospital among the contributors to drafting and review, which records where he worked at the time of that report.

Published work. His Yanhee profile lists five publications and contributions. Two of them we traced to an independent record (PubMed and the IAEA's own report); the remaining three are known to us only from the profile.

• *Scalp replantation: a case report of long ischemic time*, Journal of the Medical Association of Thailand, 2001, with W. Sirimaharaj (indexed on PubMed)
• Contributor to drafting and review, *The Radiological Accident in Samut Prakarn*, IAEA, Vienna, 2002
• *Radiation Accident in Thailand*, a contribution to the course manual of an IAEA regional training course at the National Institute of Radiological Sciences, Chiba, Japan, August 2001
• *Sensory Changes after the Sagittal Split Mandibular Setback Osteotomy*, Journal of Plastic Reconstructive and Aesthetic Surgery of Thailand, 1998
• *The Uncommon Presentation of Arteriovenous Fistula*, Srinagarind Medical Journal, 1995

The scalp replantation report belongs to reconstructive microsurgery, the IAEA items deal with a radiation accident, and the 1998 paper studies an operation that sets the lower jaw back. They reflect earlier stages of his career and are not evidence about the cosmetic procedures he performs now.

Professional societies. We separate memberships confirmed on a society's own list from those stated only on his hospital profile:

• ThPRS, the Thai plastic surgeons' national society: verified. The society's website holds a member entry for him with a Yanhee address, and its newer doctor directory at plasticsurgery.or.th shows his name with the verified-doctor badge (ผ่านการยืนยันแพทย์).
• Royal College of Surgeons of Thailand (RCST): verified. The college's member list records him as member no. 1460, in the plastic surgery field.
• ThSAPS, Thailand's aesthetic plastic surgery society: found in the society's directory of aesthetic plastic surgeons in a web-archive copy from February 2020. That directory is no longer online, so for the years after 2020 his membership rests only on his Thai Yanhee profile.
• International Society of Aesthetic Plastic Surgery (ISAPS): stated on both Yanhee profiles. He did not appear in the ISAPS public Find a Surgeon results for Thailand when we searched on 27 September 2026, but surgeons choose whether to be listed there, so his absence does not show he is not a member.
• International College of Surgeons: the English profile describes him as a Fellow.
• American Society of Plastic Surgeons (ASPS): named on the Thai profile only.

Medical licence. Practising medicine in Thailand requires a licence issued by the Medical Council (แพทยสภา). The ThPRS member entry for him gives licence number 17748. We have not yet matched that number on the Council's own register, so we suggest you search for him there before you agree to treatment.

Many of Yanhee's procedure pages end with an 'Available doctors' list naming the plastic surgeons who perform that operation. The six procedures below are those for which a Yanhee page, or Dr. Thawatchai's own Thai profile, names him. Each entry then turns to general background drawn from our procedure guides; it is not an account of how he himself works, and whether an operation suits you, and how it would be carried out, depends on his assessment of you in person.

Rhinoplasty and nasal bone reshaping

Yanhee's nose reshaping page includes Dr. Thawatchai among the plastic surgeons who perform rhinoplasty, and its ultrasonic rhinoplasty page lists him for nasal bone reshaping, including the ultrasonic (Piezo) method, in which bone is shaped with ultrasonic instruments. His Thai profile adds open rhinoplasty (เสริมจมูกแบบ Open) to his treatment experience. In general, the open approach adds a small incision across the columella, the strip of skin between the nostrils, which lets the surgeon see the nasal framework directly; the scar is usually fine and fades over time. A closed approach keeps every incision inside the nostrils. For timing, our rhinoplasty guide gives general figures rather than his own protocol: the external splint and any stitches usually come off between day 5 and day 10, which is why most visitors plan 7–10 days in Thailand, and while most swelling settles within 2–3 weeks, the tip keeps refining for a year or more. The same guide sets out the risks, among them breathing difficulty, asymmetry and the possibility of a second, revision operation.

Augmentation (Asian) rhinoplasty with an implant or rib cartilage

Yanhee's nose implant page and its rib-cartilage nose augmentation page both name him among the surgeons who perform augmentation rhinoplasty, and his Thai profile names rib-cartilage augmentation (เสริมจมูกโดยใช้ซี่โครง) specifically. The purpose of augmentation is height: a taller bridge, a more projected tip, or both. As general background, our rhinoplasty guide describes two sources for the added height: grafts of the patient's own cartilage (rib, ear or nasal septum) or a factory-made implant, silicone and ePTFE among them. The two routes trade off infection risk, feel under the skin and long-term stability differently, and a synthetic implant may migrate or extrude and then need taking out. Taking cartilage from a rib also means a second wound, on the chest. Ask Dr. Thawatchai which material he would use for your bridge and tip, and why. Our Asian rhinoplasty page lists the surgeons and hospitals we cover for this operation, with a typical time in Thailand of 7–10 days.

Facial feminization surgery

Yanhee's facial feminization surgery (FFS) page names him among the plastic surgeons who perform facial feminization procedures, without saying which parts of FFS each surgeon carries out. Several of his documented areas overlap with FFS: the nose, the chin, and endoscopic work on the brow and mid-face. His record also includes the 1998 paper on a lower-jaw operation and a 2006 workshop that took in maxillofacial surgery, yet Yanhee does not list him for jaw contouring or forehead bone reduction, so ask him directly whether he would perform those steps himself. As general guidance from our facial feminization surgery guide, a CT scan is frequently requested before any reshaping of forehead, jaw or chin bone, and visitors from abroad typically set aside 10 to 14 days in Thailand, more if the plan joins many procedures together. On hormones, WPATH's current standards (SOC-8) do not make a fixed length of hormone therapy a condition for facial surgery; individual surgeons and hospitals may apply their own criteria, so ask Yanhee what it expects. The guide also lists the risks, including numbness, nerve weakness and hair loss near incisions.

Chin augmentation

Dr. Thawatchai is one of the 'Available doctors' for chin augmentation on the Yanhee web page covering chin advancement and chin implants; that listing leaves his preferred technique unstated. In general, a chin can be brought forward either with an implant or by repositioning the chin bone itself. Ask which approach he would suggest for your profile, whether chin and nose work could be combined in one operation, and what numbness or asymmetry could follow. For planning in general terms, our chin augmentation page, which also lists providers, puts the usual time in Thailand at about 5–7 days.

Breast augmentation (endoscopic)

Dr. Thawatchai's Thai profile lists endoscopic breast augmentation (เสริมหน้าอกแบบส่องกล้อง) in his treatment experience; in an endoscopic approach, the surgeon uses a small camera to see inside the implant pocket. Generally speaking, the implant goes in through an under-breast fold, areola-margin or armpit incision, and its pocket is made above the pectoral muscle or partly under it. Ask how the endoscopic method affects those choices for your chest, and which implant shape and surface he would advise. Speaking generally, our breast augmentation guide puts the typical visit for overseas patients at 7–10 days in Thailand, many return to desk work at around one week, and hard exercise is usually put off until about six weeks. Risks include capsular contracture, implant rupture, changes in sensation and further surgery later in life; textured-surface implants are the type chiefly associated with BIA-ALCL, an uncommon lymphoma. Before you fly home, request the implant card from the hospital; it records the implant's brand, size and lot numbers.

Buttock implants

Dr. Thawatchai is among the surgeons Yanhee lists as 'Available doctors' for implant-based buttock augmentation, and his course record includes a live surgery course on gluteal implants in Bangkok in April 2007. Since our own buttock implants page has no typical stay figure yet, we offer no recovery timetable for this operation here. Ask Dr. Thawatchai about implant type and size, where the incision would sit, how sitting and sleeping are handled while you heal, and how long you should stay in Bangkok before flying. Our buttock implants page lists providers for this procedure.

On his record, but not listed as separate procedures

• Endoscopic facial rejuvenation with Endotine. Yanhee's facial rejuvenation page describes an endoscopic lift of the mid-face and brow, often secured with an Endotine fixation device, and names Dr. Thawatchai as its only available surgeon. His Thai profile calls this an Endotine face lift (ดึงหน้า Endotine), and he attended an Endotine workshop in 2017. Because the hospital's page sets this procedure apart from a facelift, we have not linked him to our facelift or brow lift guides.
• Butt lift (gluteoplasty). Yanhee's butt lift page lists him for a buttock lift that removes loose skin and adds no volume. Yanhee also performs the Brazilian butt lift, a fat-grafting operation, but none of the pages we checked names him for it.
• Chest or breast removal with an O-shaped scar. His Thai profile includes an item worded 'ตัดหน้าอก แผล O-scar'. It does not say whether this refers to breast reduction or to chest masculinization for trans men, and Yanhee's pages on female-to-male chest surgery name other members of its team, such as Dr. Sukit Warathamrong and Dr. Chokchai Amornsawadwattana. For that reason we do not list chest surgery for Dr. Thawatchai; if chest surgery is what you need, our patient team can ask the hospital to clarify.
• Correction of cosmetic surgery done elsewhere. He is on the doctor roster of Yanhee's revision centre in the Thai directory, although the roster does not specify which kinds of correction he handles. For a nose with previous surgery, our rhinoplasty guide notes that surgeons usually advise waiting at least a year after the first operation so the swelling can settle, and that a revision may need cartilage from the ear or rib. Our revision rhinoplasty page lists providers and suggests allowing 10–14 days in Thailand.

The consultation is where Dr. Thawatchai examines you and decides whether, and how, he would operate. Before you travel, one of Yanhee's international coordinators can review your case in a free online pre-assessment, but photos alone cannot fix a surgical plan; that waits until he has seen you in person in Bangkok. English is one of the two languages on his profile, so you can expect to speak with him directly in English; for other languages, Yanhee says interpreting is provided without an extra fee.

Questions for any procedure

• Do you personally perform every stage of the operation, and which anaesthetist looks after me?
• How often do you perform this particular operation at Yanhee?
• How many nights will I spend in hospital, and how many days in Bangkok before I can fly?
• What does the Yanhee package include, and what happens, and at what cost, if a revision is needed?
• After I go home, how will you follow my healing? Yanhee says it stays in contact by email and forwards the photos you send to the surgeon.

For rhinoplasty and nose augmentation

• Would you use an open or a closed approach for my nose, and why?
• If my bridge needs more height, would you use an implant or rib cartilage, and what are the trade-offs for me?
• Would the ultrasonic (Piezo) method change how my nasal bones are reshaped?
• If I have had nose surgery before, what can you tell from my records and photos, and how long after my last operation would you be willing to operate again?

For facial feminization

• Which steps would you perform yourself, and would another surgeon carry out any part, such as forehead or jaw bone work or the Adam's apple?
• Do you need a CT scan, and can you use one I already have?
• Would you combine the procedures in one operation or stage them?
• What does Yanhee require regarding hormone therapy or supporting letters?

For chin augmentation

• Would an implant or moving the chin bone suit my face better, and could it be done together with rhinoplasty?

For endoscopic breast augmentation

• What does the endoscopic approach mean in my case: which incision, and where would the implant sit?
• Which implant brand, shape and surface do you recommend, and why?

For buttock implants or a butt lift

• Am I better suited to implants, to a skin-removal lift, or to neither?
• How will sitting, sleeping and the flight home be managed during recovery?

For endoscopic brow and mid-face rejuvenation

• What can the endoscopic lift with Endotine change in my face, and when would a facelift be the better choice?

Note the answers or ask to have them in writing, especially if you are comparing surgeons. When you request a consultation, type your most important questions into the form; they travel to Yanhee alongside your request.

Dr. Thawatchai's surgery is carried out at Yanhee International Hospital, which gives its own size as 400 beds and is privately run. The hospital stands at no. 454 on Charansanitwong Road, beside Soi 90, postcode 10700, within Bang O sub-district of Bang Phlat. Joint Commission International (JCI) shows 'Yanhee Hospital' in its online directory with Hospital Program accreditation. The certificate image on Yanhee's own accreditation page gives an effective date of 13 March 2026 and names 12 March 2029 as the final day of validity. As for Thailand's own accreditation scheme, HA Thailand's database shows no current award for Yanhee, and its last listed HA period closed in 2019.

Services Yanhee describes for patients from abroad

• Registration: a desk on the first floor for international patients, where an interpreter meets you and then walks you round to each department you need
• Language: interpreting comes without an added charge, and English-speaking coordinators are stationed at points around the hospital
• Before travel: an international coordinator looks over your details in an online pre-assessment that Yanhee does not charge for
• Getting around: Yanhee can book paid airport pick-ups and hotel-to-hospital runs
• Accommodation: a set of partner hotels, cheaper if you take the room within a Yanhee package deal
• Longer stays: help extending your visa if you are admitted and treatment takes longer than planned
• In hospital: a daily visit to your room from the international liaison team
• Paying: cash in major currencies, debit or credit card, or bank transfer
• Leaving: your discharge paperwork includes a certificate confirming fitness to fly, along with a medical certificate and a summary of the admission
• Afterwards: follow-up by email once you are home, with your photos forwarded to the surgeon for review

On pricing, Yanhee says its cosmetic surgery packages normally fold theatre time, the doctor's fee, medicines, meals, nursing and your room into a single price. Ask for a written quote that shows what yours includes and excludes, and what a later revision would cost.

Planning your stay. As general guidance from our procedure guides, allow about 7–10 days in Thailand for rhinoplasty, nose augmentation or breast augmentation, about 5–7 days for chin augmentation, and 10–14 days for facial feminization surgery, with extra time if several operations are combined. These are typical ranges, not promises: Dr. Thawatchai decides when you are fit to fly after he has checked you, so flexible tickets help. Because his English profile showed clinics from Tuesday to Saturday when we checked, try to plan your first consultation and your pre-departure check for those days; our patient team confirms the current schedule.

Medical details should come to us solely via WhatsApp or the booking form, and photos can wait until Dr. Thawatchai's team requests them. Gathering the items below in advance speeds up the first review.

For every enquiry

• Name the operation and describe, in your own words, what bothers you now and what you would like to look different
• Your medical conditions, current medicines and supplements, any allergies, and your smoking or nicotine use
• Details of earlier surgery, especially in the area to be treated, with the operative notes where you have them
• The dates you could travel, and your preference between an initial video call and an in-person first meeting at Yanhee

For rhinoplasty or nose augmentation

• Nose photos in even light, once the team asks: straight on, both profiles, and the base view looking up from below
• Any breathing difficulty, past injury to the nose, or allergy affecting it
• If a nose implant is already in place, what it is made of and when it was inserted

For correction of earlier surgery

• When the first operation took place, where it was done, and its operative report or discharge summary
• Details of any implant that was used
• A short description of what you would like corrected

For facial feminization

• Front and profile photos of your face, when requested
• Any existing CT scan of the face or skull
• Whether and for how long you have taken hormone therapy, and any supporting letters you hold

For chin augmentation

• Front and side profile photos, if requested, and any history of jaw or dental surgery

For breast augmentation

• The implant card from any earlier breast surgery
• Recent breast imaging results you already have

For buttock implants or a butt lift

• Your weight history and any earlier body contouring, such as liposuction or fat grafting

If you are unsure what to include, tell our patient team which procedure you have in mind, and they will ask Yanhee what it needs for a first review with Dr. Thawatchai.
