Assoc. Prof. Dr. Prayuth Chokrungvaranont

Assoc. Prof. Dr. Prayuth Chokrungvaranont (ประยุทธ โชครุ่งวรานนท์) is a Bangkok surgeon in plastic and reconstructive surgery. The one current official page that names him is the About page published by Preecha Aesthetic Institute (PAI), a clinic for plastic surgery on Sukhumvit 55 in the Thonglor area, where he appears under “Our Surgical Team Includes” as “Asst. Prof. Dr. Prayuth Chokrungvaranont, MD”. The clinic's departments deal with gender-affirming operations for both trans women and trans men, facial feminization and aesthetic surgery.

Most of what is known about his background comes from the profile PAI used to publish for him. That page has been removed from PAI's website, but a copy saved by the Internet Archive in June 2022 survives. It records a 1982 medical degree from Chulalongkorn University Medical School, specialist residency at Chulalongkorn University Hospital, and Thai Board certification in plastic surgery in 1988. It then traces a university career in Chulalongkorn's Division of Plastic & Reconstructive Surgery, with promotion to Associate Professor in 2001.

His publications show where his clinical interests have been. PubMed lists him as a co-author of papers on sex reassignment surgery in Thailand, of a 2015 paper setting out PAI's male-to-female vaginoplasty technique, and of anatomical and clinical studies of reconstructive flaps.

Why we write “Assoc. Prof.” PAI's current About page uses “Asst. Prof.” (assistant professor). PAI's own earlier profile, however, records his promotion to Associate Professor in 2001, while the aesthetic surgeons' society ThSAPS (formally, Society of Aesthetic Plastic Surgeons of Thailand) wrote his title in Thai as รศ.นพ., the abbreviation for an associate professor who is a medical doctor. We therefore follow the later, documented title.

Missing details. Today no official page lists the specific operations Dr. Prayuth performs, so this profile does not attach any procedure to his name. PAI's doctor directory currently holds individual profiles for five surgeons, and he is not among them. If you would like an appointment with him, send a consultation request and our patient team will take it from there. Before anything is arranged, the team asks PAI to confirm that he is seeing patients and which operations he would take on.

Dr. Prayuth studied medicine and trained as a specialist at Chulalongkorn University in Bangkok. Over the following eight years he made a series of short visits to plastic, hand, craniofacial and microsurgery units in the United States, China, Taiwan and Australia. Every detail below is taken from PAI's archived profile of him.

• Medical degree (MD), 1982: Chulalongkorn University Medical School.
• Internship, 1982–1983: Chulalongkorn Hospital, Bangkok.
• Residency in Plastic & Reconstructive Surgery: Chulalongkorn University Hospital, Bangkok, completed in 1988. The profile is inconsistent about when it began: its education section says 1986, while its career list says 1985.
• Board certification, 1988: Thai Board of Plastic Surgery (published by PAI as “Diplomatic, Board of Plastic Surgery 1988” and “Thai Board of Plastic Surgery (1988)”).
• Research Fellow, 1989: Southern Illinois University at Peoria, Illinois, United States.
• Visiting doctor, 1988–1989: St. Francis Hospital in Peoria, Southern Illinois University, and, in Boston, Massachusetts General Hospital, Brigham & Women's Hospital and Children Hospital (as published).
• Visiting doctor, 1990: the Sixth People Hospital and the Ninth People Hospital, Shanghai.
• Visiting doctor, 1992: Chang Gung Memorial Hospital, Taipei.
• Visiting doctor, 1995: U.C.L.A. in Los Angeles, Christian M. Kleinert's Institute of Hand Surgery in Louisville, Kentucky, and Massachusetts General Hospital, Boston.
• Visiting doctor, 1996: the Australian Craniofacial Unit in Adelaide, the Bernard O'Brian Microsurgery Institute in Melbourne (name as PAI publishes it), and Harry Buncke's Microsurgical Unit at Davies Medical Center, San Francisco.

For the visits after 1989, PAI's profile gives only the year and the place. It does not say what each visit involved or how long it lasted, so we do not add detail of our own.

The units he visited covered hand surgery, craniofacial surgery and microsurgery, which matches the reconstructive side of his published work described below. That is a description of his training history, not evidence that he performs any of those operations today.

Dr. Prayuth's documented career runs from provincial hospital posts in southern Thailand, through a Bangkok public hospital and a university faculty, to private practice at PAI. Positions marked as past are not current.

• Attending Surgeon, Yala General Hospital, Yala (1983–1984), per PAI's archived profile.
• Director, Yaha Crown Prince Hospital, Yala (1984–1985), per the same profile.
• Attending Plastic Surgeon, Lerdsin General Hospital, Bangkok (1988–1993), after completing his plastic surgery residency.
• Academic post at Chulalongkorn University's medical faculty (Department of Surgery, plastic and reconstructive division): faculty from 1993, Assistant Professor from 1996 and Associate Professor from 2001, according to PAI's profile. His PubMed papers carry a Chulalongkorn affiliation up to 2014. On 27 September 2026 he did not appear among the current teaching staff listed by Chulalongkorn's Department of Surgery, so we treat this post as past.
• Former expert, Thai Red Cross craniofacial deformity centre at King Chulalongkorn Memorial Hospital: the centre lists him (as นพ.ประยุทธ โชครุ่งวรานนท์) among experts who have worked with it in the past.
• Committee member of ThSAPS, 2010–2012: for the 2553–2555 Buddhist-era term, a committee listing on the ThSAPS website names him as a central committee member (กรรมการกลาง).
• Current: surgical team, Preecha Aesthetic Institute (PAI), Bangkok: PAI's About page lists him under “Our Surgical Team Includes”.

Older hospital listings. The ThSAPS surgeon directory, last edited in January 2012, gave Bumrungrad Hospital on Sukhumvit Soi 3 as his workplace. PAI's older profile, archived in 2011, listed hospital privileges at King Chulalongkorn University Hospital, Bangkok Nursing Home Hospital and Phayatai Hospital (names as published). None of the three, Bumrungrad, BNH or Phyathai, had a doctor profile for him on 27 September 2026. Please read these as history, not as places where you can book him today.

The ThSAPS website also records him as one of the member surgeons who spoke on the society's public radio programme, with a talk on lip contouring (ตกแต่งริมฝีปาก) on 5 March 2013.

This site ties a procedure to a surgeon's name only where an official source states that he or she performs it. In Dr. Prayuth's case no such page exists today: his PAI profile has been taken down, and the About page gives only his name. The areas below are therefore drawn from his publications, conference papers and society roles. They show where his work has been concentrated. They do not confirm what he operates on now, so please ask our patient team to check with PAI before you plan around him.

### Male-to-female genital surgery (vaginoplasty)

This is the most consistent thread in his record. PubMed lists him as an author of:

• “Sex reassignment surgery in Thailand”, *J Med Assoc Thai*, 2004;
• a 2014 *ScientificWorldJournal* paper looking at how the surgery developed in Thailand from a social angle, where his affiliation is Chulalongkorn's Department of Surgery;
• a 2015 paper in *J Plast Surg Hand Surg* describing the male-to-female vaginoplasty method it calls “Preecha's surgical technique”, which carries only the Preecha Aesthetic Institute affiliation and sets out PAI's method.

PAI's archived profile adds conference and journal papers on the same subject: “Neoclitoris in the New Millennium” (2001), “Clitoroplasty in SRS Patient” (2004), “Labia minor Reconstruction” (British Association of Plastic Surgery, Sheffield, 2006) and “Sex Reassignment Surgery: Experiment in King Chulalongkorn Memorial Hospital” (*Thai Journal of Surgery*, 2001).

PAI's own service pages set out the male-to-female operations the clinic offers: penile inversion vaginoplasty, using penile skin alone or together with a graft of scrotal skin; colon (sigmoid) vaginoplasty; a secondary sigmoid colon procedure for revision vaginoplasty; zero-depth vaginoplasty, which our site covers under vulvoplasty; and bilateral orchiectomy. For background, our vaginoplasty guide describes the operation in general terms. Surgery is done under a general anaesthetic and commonly takes three to six hours. Afterwards, expect commonly five to seven nights on the ward and commonly three to four weeks spent in Thailand altogether, while dilation carries on long term to preserve the canal's depth. PAI carries out its general-anaesthesia operations at partner hospitals, not in the clinic building.

Before you ask for Dr. Prayuth for vaginoplasty: his authorship shows long involvement with this surgery. It does not tell you whether he would be your operating surgeon now, whether he would operate alone or alongside PAI colleagues, or which of PAI's techniques he uses. Put those three questions to PAI directly.

### Reconstructive flap and wound surgery

A second strand of his publications is reconstructive. He is listed as a co-author on anatomical studies of the deep inferior epigastric perforator (DIEP) flap for breast reconstruction (*J Med Assoc Thai*, 2006) and of the thoracodorsal artery perforator flap for covering shallow defects (2007). Other co-authored papers cover bilateral scrotal flaps to restore skin after penile paraffinoma, which is damage caused by injected paraffin (2005); a SMAS flap used during parotid gland surgery to prevent Frey's syndrome, which is sweating of the cheek when eating (2004); and a pilot comparison of wound dressings for partial-thickness wounds (2010). His visiting posts at microsurgery and craniofacial units, and his former link with the Thai Red Cross craniofacial centre, belong to the same side of his career.

What this means for you: none of this reconstructive work is listed as a current service of his at PAI, and PAI's service pages concentrate on gender-affirming, facial feminization and aesthetic surgery. If your need is reconstructive, tell our patient team. We will ask PAI whether he accepts such cases rather than assume he does.

### Aesthetic plastic surgery

Dr. Prayuth was listed in ThSAPS's own directory of aesthetic plastic surgeons, sat on the society's committee for 2010–2012 and gave a public radio talk for the society on lip contouring in 2013. PAI's aesthetic department offers a broad range of face, breast and body procedures, listed on our PAI page. No official page connects him to any particular one of them, so if you are interested in an aesthetic procedure, ask the patient team to find out whether he or another PAI surgeon would see you.

Dr. Prayuth's published work centres on male-to-female surgery, so most enquiries about him are likely to concern vaginoplasty. The questions below pair what is specific to PAI with the general guidance in our vaginoplasty guide. Whether any operation suits you can only be decided after an individual assessment.

About who operates

• Will Dr. Prayuth assess me himself, and will he be the operating surgeon? If PAI works as a team, who else will be in theatre and who will see me at follow-up visits?
• Is he currently operating at PAI's affiliated hospitals, and which hospital would my operation take place in?

About the technique

• Which of PAI's options would he suggest for my body, and why? PAI's pages describe penile skin inversion on its own or with a scrotal graft, a sigmoid colon method, and a zero-depth option. As general background, penile inversion is the most established approach, and using a length of bowel is generally kept for cases such as revisions or when too little skin is available.
• If I am weighing a full-depth canal against vulvoplasty, what would each mean for me? In general, vulvoplasty creates no canal and so avoids long-term dilation.
• How are the clitoris and labia formed? This is a reasonable question for him in particular, given his papers on neoclitoris, clitoroplasty and labia minora reconstruction.

About eligibility and preparation

• Which documents does PAI ask for? As general guidance, many Thai surgeons follow the WPATH guidance known as SOC-8 (Standards of Care, Version 8). Before genital surgery it describes assessment by a suitably qualified health professional plus, unless clinically inappropriate or not wanted, at least six months of hormone therapy beforehand. A number of surgeons still ask for two letters, so check exactly what PAI needs from you.
• Does he require the hair on the skin used for the canal lining to be permanently removed, and how early should I start? Electrolysis or laser can take several months.
• Do I need to pause or adjust any medicines, hormones included, before the operation?

About recovery and risk

• How many nights would I be in hospital (commonly five to seven), and how long should I stay in Thailand (commonly three to four weeks)?
• What dilation schedule would I follow, and are dilators and medication part of the package?
• Which complications does he plan for, and how would they be managed? In general terms, our vaginoplasty guide lists these possible problems: bleeding; infection; wounds that heal slowly; urinary trouble such as a spraying stream or a narrowed opening; narrowing of the canal or loss of its depth; changes in feeling; and, rarely but seriously, a rectovaginal fistula, meaning an abnormal opening between the canal and the bowel. Ask PAI for its own complication and revision rates.
• If a secondary procedure is needed later, who would perform it, and where?
• When could I return to work? For desk work, the general guide gives often around six to eight weeks, with heavy lifting and sex usually waiting longer.

About aftercare at home

• Can PAI give me an English copy of my operation notes to take to my doctors at home?
• How does PAI stay in touch by email once I am back home?

Finding the clinic. PAI's address is 898/1 Sukhumvit 55 (Thonglor), across the road from Thonglor Soi 23, Khlong Tan Nuea, Watthana, Bangkok 10110.

What happens where. According to PAI, the clinic building is used for consultations, medical health checks and follow-up visits. It has 10 consultation rooms, recovery rooms and operating rooms for local-anaesthesia work; the About page counts six of those operating rooms, while some service pages say four. Anything that needs a general anaesthetic is done at one of two affiliated private hospitals, which PAI calls JCI-accredited. The photos in PAI's hospital gallery carry the names Phyathai 2 Hospital and ViMUT Hospital, and on 27 September 2026 both names returned an accredited listing when we searched Joint Commission International's online directory. The clinic has no entry of its own in either that directory or the HA Thailand listings. If Dr. Prayuth takes your case, ask which of the two hospitals he would operate in.

Help PAI describes for patients from abroad.

• A driver meets you at Suvarnabhumi Airport once you have cleared customs; PAI names door 4 as the meeting point.
• Depending on your package, transport linking the airport, clinic, hospital and your hotel, plus local trips within 2 km of the clinic while you attend follow-up, is either included or an optional extra.
• Bookings at partner hotels close to the clinic, at corporate rates.
• An interpreter, whatever language you speak.
• If your visa application needs supporting paperwork, PAI can write to your embassy or passport office.

Languages. Thai and English are the two languages PAI's archived profile gives for Dr. Prayuth. For the clinic as a whole, the contact page names nine: Thai, English, Japanese, Chinese, French, German, Italian, Spanish and Turkish.

Contact before you fly. PAI's service pages explain that an overseas patient's first consultation happens by email, with the attending physician reviewing what the patient sends. Video calls are not part of PAI's process, so expect written exchanges before you travel and a physical examination once you reach Bangkok.

Length of stay. For vaginoplasty, our general guide plans for three to four weeks in Thailand, with about the first week on a hospital ward. A companion can help during that time. A return ticket you can change is also useful, because the date you fly home depends on your surgeon's review of your healing.

Clear information at the start lets PAI's attending physician review your case by email and give you a realistic answer. Share documents only by the route our patient team suggests, never in public messaging groups.

For vaginoplasty, vulvoplasty or orchiectomy

• Your name exactly as printed in your passport, your date of birth, where you live and when you hope to travel.
• Your hormone history: when you started, what you take now and at what dose, and who prescribes it.
• Any assessment or referral letters from a qualified health professional. If you are unsure what PAI requires, send what you have and ask.
• Your medical history: long-term conditions, mental health care, bleeding or clotting problems, allergies, current medicines and supplements, smoking or vaping, and your height and weight.
• Previous surgery, especially any orchiectomy or earlier genital surgery.
• How much hair removal you have had, and by which method.
• Your goals: whether you want a canal (full depth) or are considering zero depth, and anything that matters to you about appearance, sensation or recovery time.

For revision vaginoplasty

• The operation notes, the name of the surgeon and hospital, the date and the technique used.
• A description of the problem now, for example narrowing, loss of depth, urinary symptoms or concerns about appearance.

About photographs. Do not send intimate photographs unless PAI asks for them. Our patient team will tell you if they are needed and how to send them securely.

For other enquiries (aesthetic or reconstructive)

• A short description of the concern and what you hope to change.
• If PAI asks for them, clear unfiltered photos of the area in even light, one from the front and one from each side.
• Details of any previous operation on that area, including when it was done and any notes you kept.

Whatever your procedure, include the questions you most want Dr. Prayuth to answer. Knowing them in advance helps PAI judge whether his skills match what you need.
