Dr. Premsuda Sombuntham

Dr. Premsuda Sombuntham (Thai: พญ. เปรมสุดา สมบุญธรรม) is a Bangkok ear, nose and throat specialist (otolaryngologist) whose published subspecialty is laryngology, the branch of ENT that deals with the voice box (larynx), the vocal folds and the upper airway. On her Bumrungrad profile, her special clinical interest reads laryngology and head and neck surgery; her staff page at Chulalongkorn University adds diseases of the larynx and operations to correct narrowing of the upper airway.

Her documented practice is split between two Bangkok hospitals:

• [Bumrungrad International Hospital](/hospital/bumrungrad-international-hospital/), privately run and located on Sukhumvit Soi 3 in Watthana. She holds clinics in its ENT Center (Building A, 12A) and is listed as laryngologist for the voice service of its Pride Clinic.
• [King Chulalongkorn Memorial Hospital](/hospital/king-chulalongkorn-memorial-hospital/) in Pathumwan, the hospital where Chulalongkorn University's medical school teaches. She is on the staff of the university's Department of Otolaryngology, whose timetable lists her for outpatient sessions, a laryngology clinic and operating days.

Why a laryngologist appears on a cosmetic and gender-affirming surgery site: Bumrungrad's Pride Clinic, its service for LGBTQ+ patients, has a page on gender-affirming voice and communication care for transwomen. It describes two strands of care, sessions with a speech-language pathologist to train voice and communication, and voice surgery that can modify the vocal cords, and it gives Dr. Premsuda Sombuntham as the laryngologist for that service. On that basis we list her for voice feminization; no official page ties her to any other procedure on our list.

To be clear about her field: Dr. Premsuda is an ENT surgeon, not a plastic surgeon. Both her residency and her board certificate are in otolaryngology. Nor does her name appear on the member roll that the Thai plastic surgery society, ThPRS, publishes; for someone whose whole specialist path is ENT, that is expected rather than a gap in her record. Her personal Bumrungrad profile covers ENT and laryngology only and says nothing about gender-affirming care; the connection rests on the Pride Clinic page alone. That page lists a different set of doctors under the heading 'Transgender Plastic Surgeons'.

If voice feminization in Bangkok is what you are exploring, you can request a consultation with Dr. Premsuda Sombuntham; we relay it to the hospital and write back once an appointment is confirmed, since nothing is reserved automatically. For how the facts about Dr. Premsuda were gathered and checked, read our provider research methodology.

Three official sources describe Dr. Premsuda's training: her English-language and Thai-language profiles at Bumrungrad, and her staff page in the Department of Otolaryngology at Chulalongkorn University. Where they differ, both versions are shown below rather than one being picked.

Medical degree, Chulalongkorn University (2000). Her M.D. comes from Chulalongkorn University's Faculty of Medicine and was completed in 2000. The English Bumrungrad profile records it as M.D. (Honors), and the Thai version is more specific: เกียรตินิยมอันดับสอง, meaning honours of the second class.

Otolaryngology residency, Chulalongkorn Hospital (2003–2006). Specialist ENT training followed at Chulalongkorn Hospital, with the dates published as 2003 to 2006.

Thai Board of Otolaryngology (2006). Bumrungrad's English profile gives her board status as Diplomate, Thai Board of Otolaryngology, 2006. The Chulalongkorn department page records the same ENT certificate (the Thai วุฒิบัตร, dated 2006) and gives แพทยสภา, the Medical Council of Thailand, as its issuer. It is the Thai certificate that marks a doctor as a specialist in her field.

Clinical fellowship in laryngology, University of Toronto (ended 2013). After certification she went to Canada as a Clinical Fellow in Laryngology at St. Michael's Hospital, University of Toronto. The three sources agree on 2013 as the end year but not on the start: the English Bumrungrad profile gives July 2010 to June 2013; the Thai profile gives July 2012 to June 2013 (written in the Buddhist-era calendar as 2555 to 2556); and the Chulalongkorn page lists the fellowship under 2013 without a start date. Because we cannot settle which is right, this page does not state the length of the fellowship.

Why this matters if you are considering voice surgery. In general, a laryngology fellowship is a period of focused training after ENT residency on the larynx itself: voice disorders, vocal fold conditions and the upper airway. For a trans woman weighing voice feminization, the practical point is that Dr. Premsuda's documented training centres on the organ that voice surgery changes. Neither of her profiles lists dedicated training in gender-affirming surgery, and no official page states how many voice feminization operations she carries out. Those are fair questions to put to her directly, and the consultation section below suggests how.

Licence check. 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. Her ENT board certificate is documented on a Chulalongkorn University page; the register entry itself we have not seen. Before you travel, you can look her up on the register using her Thai name (เปรมสุดา สมบุญธรรม) or her English name.

Official pages show Dr. Premsuda in three current roles. No source dates the start of any of them, and we therefore give no length of service for her.

Department of Otolaryngology, Chulalongkorn University. She is on the teaching staff of ภาควิชาโสต ศอ นาสิกวิทยา, the ENT department of Chulalongkorn University's Faculty of Medicine, whose doctors staff King Chulalongkorn Memorial Hospital. Two university sources disagree on her academic rank. The department's staff page, staff list and clinic schedule call her Assistant Professor (ผู้ช่วยศาสตราจารย์); the Faculty of Medicine staff directory calls her Lecturer (อาจารย์). We use the title Dr., as Bumrungrad and its Pride Clinic do, until the rank is confirmed. According to the department's clinic timetable, she covers official-hours ENT outpatient sessions on Monday morning and afternoon and on Thursday morning, the laryngology clinic (คลินิกโรคกล่องเสียง) in the 13:00–16:00 Thursday slot, and theatre days Wednesday through Friday.

ENT Center, Bumrungrad International Hospital. At Bumrungrad she is listed under Otolaryngology with laryngology as her subspecialty, based in the ENT Center (Building A, 12A). When we checked on 27 September 2026, her published hours there were Wednesday 17:00–20:00 and Saturday 10:00–16:00. Clinic hours at Bumrungrad can shift, which is why her current days are rechecked with the hospital for each request we pass on.

Pride Clinic, Bumrungrad International Hospital. The Pride Clinic's page on gender-affirming voice and communication care, filed under Transwomen Health, names her as the service's laryngologist. The page pairs training with a speech-language pathologist with voice surgery that can modify the vocal cords.

Published research. PubMed records list her as a co-author on papers with a Chulalongkorn University ENT affiliation. Several deal with the voice and throat:

• two-part practical guidelines on chronic cough, one on screening and investigation and one on treatment, in the *Asian Pacific Journal of Allergy and Immunology* (2024);
• a descriptive study of how common dysphonia (a voice disorder) was among Thai COVID-19 patients treated outside hospital, and which factors went with it, assessed with the Thai-VHI10 voice questionnaire, in *Asian Biomedicine* (2024);
• a paper on narrow band imaging to detect sulcus vocalis, a vocal fold condition that is easily missed, in *QJM* (2023);
• older work on a drug-releasing silicone surface for medical devices (*ACS Applied Materials & Interfaces*, 2014) and a pilot study using SPECT/CT imaging before surgery to predict whether papillary thyroid cancer had spread to neck lymph nodes (*Journal of the Medical Association of Thailand*, 2013).

None of these papers concerns gender-affirming voice surgery, and none reports outcomes of her own operations. What they do show is academic work on the larynx and upper airway, in line with her listed interests.

Memberships. Her official profiles name no professional society membership, so none is shown here.

Of the procedures on our list, voice feminization is the only one an official source links to Dr. Premsuda. Below, what Bumrungrad documents about her role is kept apart from general information about voice feminization that applies at any hospital.

What Bumrungrad documents. The Pride Clinic's voice and communication page for transwomen states that the service offers voice surgery able to modify the vocal cords, together with voice and communication training led by a speech-language pathologist, and it names Dr. Premsuda Sombuntham as the laryngologist. It does not name the operation used (glottoplasty or cricothyroid approximation, for instance), and it publishes no results, case numbers or prices. Her individual profile does not mention voice feminization, so the Pride Clinic page is the single official link between her and this procedure.

In general: why surgery is considered. Once testosterone has acted on the vocal folds, oestrogen cannot undo the effect, so for most trans women the speaking pitch stays where it was on hormone treatment alone. Pitch is only one part of what makes a voice read as feminine; resonance, intonation and patterns of speech carry much of it. Therapy can address every one of those elements, whereas an operation alters pitch alone. For that reason our voice feminization guide puts work with a speech-language therapist first, and the WPATH Standards of Care, version 8, and the UCSF gender-affirming care guidelines both count voice and communication support as part of care. Bumrungrad's arrangement, with a laryngologist and a speech-language pathologist in one service, is consistent with that approach.

In general: the two operations you may hear about. Our procedure page outlines two techniques. In glottoplasty, of which the Wendler technique is one version, the surgeon works through the mouth to reduce the length of vocal fold that vibrates, so there is no cut on the neck; it is the approach most often used at present. Cricothyroid approximation instead tightens the vocal folds through a small incision in the neck, and the higher pitch it gives can drift down over time. Since Bumrungrad does not say which technique its voice surgery uses, ask Dr. Premsuda which one she would propose for you, and her reasons.

In general: what recovery involves. The operation is usually brief and done under general anaesthesia, and patients stay in hospital for no more than one night. A strict voice-rest period of about a week, with no speaking at all, commonly follows; after that, speech is reintroduced step by step under the guidance of the surgeon and the voice therapist. In the early weeks the voice may be husky or lack strength, and it goes on changing for weeks to months. Voice therapy after the operation is usually advised so that the raised pitch settles into natural-sounding speech. Our procedure guide suggests allowing roughly 7–10 days in Thailand, long enough to be seen after voice rest ends.

Risks and realistic expectations. In general, the rise in pitch can turn out smaller than hoped; the voice can lose loudness or range, or sound hoarse or rough; and breathing or swallowing difficulties are rare but possible. Singing may be affected. Outcomes differ from person to person, and no surgeon can promise a target pitch. Whether surgery suits you is decided only after Dr. Premsuda has assessed your voice and larynx, and these risks are worth going through with her in detail beforehand.

Related procedures she is not documented for. Patients often raise neighbouring procedures, so here is what the official pages do and do not show:

• Tracheal shave (Adam's apple reduction). Chondrolaryngoplasty, or thyroid cartilage shaving, appears on the Pride Clinic's list of procedures for transwomen, but no official page names Dr. Premsuda as the surgeon for it. A tracheal shave is often done in the same session as glottoplasty on request; if you want both, ask which Bumrungrad doctor would perform each part and whether one operation can cover them.
• Voice masculinization. Bumrungrad's voice surgery page is aimed at transwomen, and we found nothing official linking Dr. Premsuda to voice masculinization for trans men.
• Facial feminization and other gender-affirming operations. These fall under plastic surgery. The Pride Clinic lists other doctors as its transgender plastic surgeons, and these operations are not part of Dr. Premsuda's documented practice.

Her other listed interests, diseases of the larynx and surgery for upper airway narrowing, belong to general ENT practice rather than cosmetic or gender-affirming surgery, so they are not on our procedure list.

At a first consultation, Dr. Premsuda would assess your voice and examine your voice box, then discuss whether surgery, therapy or a combination suits you. Only that individual assessment can establish whether any procedure is appropriate. The questions below target the gaps in what is published about her practice.

About your voice and what you want from it

• How will you examine my larynx, and will you record or measure my voice now so the result can be compared later?
• Based on the voice therapy I have already done, have I reached the limit of what therapy can give me, or is more therapy the better next step?
• Is the pitch and overall sound I am hoping for achievable with surgery in my case?

About the operation

• Would you recommend glottoplasty or cricothyroid approximation for me, and what is your reasoning?
• Will I have general anaesthesia, and should I expect to stay a night in hospital?
• Will I have any visible scar on my neck?
• If I want a tracheal shave too, which doctor would do it, and could both be done in one operation?

About her experience and the team around her

• Roughly how many voice feminization operations do you do in a year? This figure is not published anywhere official, so asking is reasonable.
• Will the Pride Clinic's speech-language pathologist see me before and after the operation, and how often?
• Where exactly will the surgery take place, and who is responsible for my care if a problem arises while I am in Bangkok?

About recovery and the trip home

• How long will my strict voice rest last, and when may I start speaking?
• When will you review my voice after surgery, and when will I be fit to fly?
• Can follow-up appointments or voice therapy continue online after I go home?
• If my voice or breathing gets worse after I return, what should I do and whom should I contact?

About cost

• Which items does the estimate cover: surgeon's fee, anaesthesia, the hospital stay, voice therapy sessions and follow-up visits? Bumrungrad's Medical Coordination Office states that it can give international patients estimated prices before they arrive.

Bring your questions in writing and note down the answers, or come with someone who can. If surgery is going ahead during your trip, keep in mind that you will not be allowed to talk during voice rest, so it is better to settle open questions before the operation than after it.

Dr. Premsuda's two hospitals differ a great deal, and published arrangements for overseas patients cover mainly one of them.

Bumrungrad International Hospital. This private hospital sits on Soi Nana Nua (Sukhumvit Soi 3); its full address is 33 Sukhumvit 3, Wattana, Bangkok 10110. Her ENT clinics take place in Building A (12A), and the Pride Clinic's counter is in the same building on the 16th floor (counter A). In the Joint Commission International directory the hospital appears as accredited under the Hospital Program, first effective in February 2002. HA Thailand's records show it holding Advanced Hospital Accreditation; the latest renewal dates from 23 May 2025 and is valid to 22 May 2029. The Global Healthcare Accreditation directory has listed it since 2017 under its accreditation for medical travel.

Bumrungrad publishes the following support for international patients, which is relevant if you are flying in for voice surgery:

• Medical Coordination Office (Building A, 10th floor), This free office is run by coordinating physicians and nurses. For a voice patient that means earlier laryngoscopy reports and therapy notes can be reviewed before you fly, a cost estimate and appointment arranged, and a telemedicine session set up; after discharge the same office issues medical reports and fitness-to-fly documents and coordinates follow-up.
• Interpreting. A voice consultation depends on describing sound precisely, so language matters: Bumrungrad lists a pool of more than 130 interpreters in its factsheet, and Cultural Support Officers help overseas patients for whom English is not the first choice.
• Airport and local transport. Landing at Suvarnabhumi, look for Bumrungrad's airport representative in the international arrivals hall; the desk sits by Exit C at Gate 9 and is staffed 07.00–23.00 daily. A complimentary van leaves the airport for Bumrungrad and hotels close to it roughly every hour, though departures depend on passenger demand, and, for trips within the city, free vans shuttle every day between the hospital and two Skytrain stops, Nana and Phrom Phong.
• Visas and travel bookings. If your recovery runs past your visa, the Business Center can arrange an extension for you or a companion by working with the Bangkok Immigration Office; the same desk books hotels and flights.

Thai and English are the languages on her Bumrungrad profile. Should you want the consultation in a third language, note it on the request form and we will ask Bumrungrad for an interpreter.

King Chulalongkorn Memorial Hospital. Dr. Premsuda's Thursday laryngology clinic belongs to a Thai Red Cross Society hospital that doubles as the university's medical teaching base; patients attend it at 1873 Rama 4 Road; the district is Pathumwan and the postcode 10330. It carries HA Thailand's Advanced Hospital Accreditation, re-awarded in May 2025 and expiring on 22 May 2029. Our research turned up no official page on international patient services there, such as interpreters, an international desk or airport pickups, so overseas visitors should not count on them. Her sessions there belong to the ENT department's official-hours outpatient timetable. The hospital also runs a Gender Health Clinic, but no official page we read connects Dr. Premsuda to it.

Planning your stay. For voice feminization, our procedure guide suggests allowing around 7–10 days in Thailand so that you are still in Bangkok for the check after voice rest; when you can fly home is for your surgeon to decide. A changeable return ticket helps. Pack a notepad or have a notes app ready on your phone, since you will not be allowed to talk for a while. Both hospitals are in central Bangkok, and our Bangkok guide covers the city more broadly.

Voice surgery is planned from your history, a voice assessment and an examination of the larynx, so photographs play a much smaller part than they do for facial surgery. Sending the following ahead of your consultation with Dr. Premsuda gives her and Bumrungrad's coordinators a clearer picture:

• Your aim, described by you. How you would like your voice to sound, and what bothers you most at present: pitch, being misgendered on phone calls, fatigue after long conversations, or something else.
• Voice therapy so far. Whether you have had sessions with a speech-language therapist or pathologist, over what period, and what changed. A report from your therapist is helpful.
• Hormone treatment. Whether you take gender-affirming hormones, which ones, and since when.
• Previous examinations of your vocal folds. Any reports, images or video from an earlier laryngeal examination, and any diagnosis you received.
• Past surgery on the neck or throat. In particular a previous tracheal shave, thyroid surgery, earlier voice surgery or occasions when you were intubated (had a breathing tube), and any complications.
• Your general health. Medical conditions, allergies, every medicine you take (supplements and blood thinners included), earlier reactions to an anaesthetic, and any smoking or vaping.
• Your voice demands. Whether you sing, teach, spend long hours on the phone or otherwise rely heavily on your voice, since singing can change after surgery.
• An optional recording. A short sample of normal speech or reading aloud, recorded on your phone, can be a useful starting point. It is no substitute for an examination.
• Travel dates. When you are free to travel and how many nights in Bangkok your plans allow, bearing in mind the silent voice-rest week and the check that follows it.
• Language. The language you would like for the consultation, and whether you need an interpreter.

Send only what you feel comfortable sharing in advance; the rest can wait for the appointment. No one can confirm that surgery is right for you until you have been examined.
