Dr. Tharatip Likkasittipan

Dr. Tharatip Likkasittipan (Thai: นพ. ธราธิป ลิขสิทธิพันธุ์) is a Bangkok-based otolaryngologist, meaning an ear, nose and throat (ENT) surgeon, whose specialty also covers head and neck surgery. On the medical team pages of Kamol Cosmetic Hospital his title is 'Otolaryngologist, Head and Neck', and the Areas of Expertise on his Kamol profile include voice feminization surgery and voice masculinization surgery. The overview on the same profile says he now focuses his practice on gender-affirming voice surgery. That is why ThaiCosmeticSurgery.com places him in its gender-affirming section and links him to two procedures only: voice feminization and voice masculinization.

Both operations are performed on the larynx, the voice box at the front of the neck. The larynx falls within otolaryngology, head and neck surgery, which is the specialty in which Kamol says he holds Thai board certification. He is not a plastic surgeon, and his Kamol page links him to none of the face, breast, body or genital operations that other Kamol surgeons provide. If you are planning several procedures in one trip, ask Kamol which surgeon operates on which area and how the surgeons coordinate a combined session.

Beyond Kamol, Bangkok Hospital keeps a current profile for him, filed under Otolaryngology in the Ear Nose Throat Center of Bangkok Hospital (Headquarters). The team page of the Pepper Research Lab at Stanford Medicine in the United States names him as a visiting scholar researching facial nerve reanimation and facial reconstruction, and describes him as a head and neck surgeon at Rajavithi Hospital in Bangkok.

The essentials, as published in the sources behind this profile:

• Specialty: otolaryngology, head and neck surgery, with Thai board certification according to Kamol; on this site, gender-affirming voice surgery
• City: Bangkok
• Hospitals: Kamol Cosmetic Hospital in the Wang Thonglang district, and Bangkok Hospital (Headquarters)
• Procedures documented for him: voice feminization and voice masculinization
• Languages: English and Thai, as recorded on his Bangkok Hospital profile
• Professional body: RCOT, the Thai royal college of otolaryngologists; his name appears in its online member directory

To ask for an appointment with Dr. Tharatip, fill in the consultation request form for him. Our patient team forwards it, learns which dates Dr. Tharatip has open and writes back to you. Until you receive that confirmation from us, the request is only an enquiry and no slot is held.

Two hospital profiles publish Dr. Tharatip's education, one on Bangkok Hospital's website and one on Kamol's. Taken together, and in only as much detail as each source gives, they describe this path:

• Doctor of Medicine, First Class Honors, Mahidol University (2013). From his Bangkok Hospital profile.
• Otolaryngology, Rajavithi Hospital (2019). Also from the Bangkok Hospital profile, which puts it under Education without naming the type of programme. For that reason we do not call it a residency, even though it is in the same field as his board certification.
• Board certification in Otolaryngology, Head and Neck Surgery (Thailand). The Kamol profile gives the qualification's Thai name, วุฒิบัตรสาขาโสต ศอ นาสิกวิทยาและศัลยกรรมศีรษะ-ลำคอ, but states neither the year nor the certifying body.
• Fellowship in Head and Neck Oncology (2024). Kamol gives the awarding body only as 'Royal College of Otolaryngologists', without saying which country's college is meant.
• International Certificate, IFHNOS (2024). Shown on the Kamol profile by its abbreviation alone, which the profile does not expand.

Head and neck oncology is the surgical care of tumours and cancers in the head and neck, and his Kamol profile pairs it with a further interest in facial and neck reconstruction. His research post runs along the same line: the Stanford Pepper Research Lab describes his work there as research into facial nerve reanimation and facial reconstruction, aimed at restoring facial function for people with facial paralysis. The one publication we could link to him also comes from head and neck surgery, a 2020 study of why oral cancer is diagnosed late (details in the next section).

For a voice patient, the gaps matter as much as the entries. No profile we read records a laryngology fellowship or course (laryngology being the ENT sub-field for the voice box and voice), nor any training specific to gender-affirming voice surgery. None says where or when he started performing voice feminization or masculinization, or how many of these operations he has carried out. That is a gap in what has been published, not proof that such training is absent. Voice surgery is a small and technical field, so it is sensible to ask Dr. Tharatip at your consultation how he learned the voice techniques he uses and how often he performs them.

Kamol Cosmetic Hospital, Bangkok. Kamol files him under its General Surgeons and Specialist Surgeons rather than among its plastic surgeons, with the title 'Otolaryngologist, Head and Neck'. His Kamol page is the only source we found that names specific operations he performs, and it is the basis for his listing here. Kamol's service pages cover feminizing and masculinizing procedures alike, with separate pages for voice feminization and voice masculinization, so his voice work forms one part of a broader gender-affirming service at the hospital.

Bangkok Hospital (Headquarters), Bangkok. Bangkok Hospital's website carries a current profile for him in the Ear Nose Throat Center, under Otolaryngology, with his languages and education. On 27 September 2026 that page showed no clinic hours and directed patients to call the hospital. It names no procedures, so we have no source stating that he performs voice surgery at Bangkok Hospital. Patients who prefer Bangkok Hospital for a voice consultation can say so in the booking form, and we will enquire there on their behalf.

Rajavithi Hospital, Bangkok. According to the Stanford lab page, he is a head and neck surgeon at Rajavithi Hospital whose work centres on head and neck cancer surgery and reconstructive procedures. The page is undated, so this role is recorded as stated by Stanford rather than confirmed by the hospital. We do not arrange consultations at Rajavithi.

Pepper Research Lab, Stanford Medicine, USA. The lab's team page lists him as a visiting scholar studying facial nerve reanimation and facial reconstruction.

Publication. A 2020 article in the Journal of The Department of Medical Services (Thailand), 'Factors of Delayed Diagnosis of Oral Cancer in Rajavithi Supertertiary Care Hospital', names him as an author from the Center of Excellence in Otolaryngology Head and Neck Surgery at Rajavithi Hospital. The journal spells his surname 'Likkasitipun', which helps if you search for his work. PubMed returned no record for him under either spelling.

Professional body and licence. The ENT college RCOT (formally, Royal College of Otolaryngologists-Head & Neck Surgeons, Thailand) keeps an online member directory. A search there for his Thai name returns 'นพ. ธราธิป ลิขสิทธิพันธุ์', so we show the membership as found on the college's own list; the Kamol profile itself claims no memberships. A licence confirmation for him would come from the doctor register that Thailand's Medical Council publishes online (checkmd.tmc.or.th); you can search it yourself by name. Anyone can repeat that search by name.

Kamol's Areas of Expertise list for him gives two procedures, and they are the only ones documented for Dr. Tharatip. Anything below that is not about him specifically is general guidance from our own procedure pages, included to help you prepare questions. It does not describe how he operates, because his profiles do not set that out.

Voice feminization surgery (VFS)

What is documented: 'Voice Feminization Surgery' appears among his areas of expertise at Kamol, and Kamol Cosmetic Hospital has its own voice feminization service page.

In general: oestrogen does not reverse the effect testosterone has already had on the vocal folds, so pitch usually stays low on hormones alone. Whether a voice is heard as feminine depends on pitch, resonance, intonation and speech patterns. Voice therapy with a speech-language therapist can work on all four, while surgery changes pitch only, which is why therapy is usually the first step and is usually recommended again after an operation. The two operations described on our voice feminization page are glottoplasty, which shortens the vibrating part of the vocal folds from inside the throat and leaves no neck scar, and cricothyroid approximation, which tightens the vocal folds through a small neck incision and whose pitch rise can lessen over time. Surgery is usually done under general anaesthesia, with either no overnight stay or one night in hospital, followed by about a week of strict voice rest and then a gradual return to speaking. The voice often sounds hoarse or weak at first and keeps settling over weeks to months.

Possible downsides include a smaller rise in pitch than hoped, a quieter voice or narrower range, hoarseness, a rough voice quality, changes to singing and, rarely, breathing or swallowing problems. Only an individual examination of your voice and larynx can show whether any of this surgery is right for you.

What is not documented: which of these techniques Dr. Tharatip uses, whether he adapts the choice to each patient, and how many voice feminization operations he performs. Ask about all three.

Voice masculinization surgery (VMS)

What is documented: 'Voice Masculinization Surgery' is also among his areas of expertise, and the overview on the same profile mentions voice feminization or masculinization surgery together. Kamol also has a voice masculinization service page.

In general: voice masculinization aims to lower the pitch of the voice. Our procedure page for it does not yet carry a full guide, so techniques and recovery times are left out here. Because testosterone itself usually changes the voice, expect Dr. Tharatip to ask how long you have been taking it and how your voice has responded. Ask him in turn what surgery could add to that, which operation he would propose, what voice rest and follow-up it needs, and whether he recommends voice therapy alongside it.

Tracheal shave and other procedures at Kamol

Kamol Cosmetic Hospital offers a tracheal shave (Adam's apple reduction), and our voice feminization guide notes that surgeons often combine glottoplasty with a tracheal shave when a patient asks. Dr. Tharatip's profile does not list tracheal shave, so we do not link him to it. Anyone wanting the two together should ask whether he would carry out both parts or whether another Kamol surgeon would do the tracheal shave in the same session. The same question applies if you are combining voice surgery with facial feminization or facial masculinization, both of which Kamol also offers.

Head and neck oncology and facial reconstruction

The Kamol profile also lists head and neck oncology surgery and facial and neck reconstruction among his interests. These are not cosmetic or gender-affirming procedures, and they fall outside what this site covers. If you need care for a head and neck tumour, contact a hospital directly.

A voice surgery consultation is where you find out whether an operation is likely to help your voice, and whether Dr. Tharatip is the surgeon you want to perform it. Because his published profiles say little about his voice-surgery methods, the consultation is also your main source for those details. These questions follow from what is and is not documented about him:

• Training and volume. How did you train in gender-affirming voice surgery, and roughly how many voice feminization or masculinization operations do you perform in a year?
• Technique. Which operation would you recommend for my voice, and what makes it a better fit than the other options? Will there be a scar on my neck?
• Realistic result. What change in pitch is realistic for me, how might loudness, range or singing be affected, and how do you assess the voice before and after surgery?
• Assessment. What examination of my throat and voice do you need before confirming that I am suitable, and can any of it be arranged before I travel?
• Voice therapy. Do you want me to have therapy before surgery? Can a speech-language therapist see me in Bangkok, and what should my therapist at home do afterwards?
• Where and how. Is the operation done at Kamol Cosmetic Hospital or at another hospital, who administers anaesthesia, and is an overnight stay needed?
• Voice rest and follow-up. How long must I stay silent, when is my check-up, and when can I fly home?
• Combined procedures. If I also want a tracheal shave or facial surgery, who performs each part, and can they be done together?
• After I leave Thailand. How do you follow up remotely, and what happens if my voice does not settle as expected or I have a complication after returning home?
• For voice masculinization. How does my testosterone history change what surgery can add?

In general, no surgeon can promise a particular pitch, and results vary between individuals; a consultation that is frank about limits is more useful than one that is not. Kamol's contact page offers a secure video call with one of its surgeons to patients who cannot fly out immediately, so part of this list can be covered before you commit to flights. The decision that surgery suits you still follows an in-person examination in Bangkok.

The hospital. Kamol Cosmetic Hospital (โรงพยาบาลศัลยกรรมตกแต่งกมล) stands at number 1223 on Inthraphon Road by Lat Phrao 94, Wang Thonglang, with the postal code 10310. The JCI (Joint Commission International) search page showed Kamol as 'Accredited' when we looked it up for this profile on 27 September 2026. Kamol says its building was designed around demanding aesthetic and gender-affirming operations. The 4th floor is given over to theatres, a microsurgical one and an endoscopy-equipped suite among them, with monitored recovery (11 beds) next door; the number of operating rooms, seven, appears only on Kamol's Thai-language facilities page. Inpatient ward rooms are on the 5th and 6th floors, and the 7th floor holds medical residence apartments. You register and meet surgeons on the 3rd floor. The 2nd floor has a diagnostic and wellness centre offering in-house lab tests, X-ray and ultrasound imaging, ECGs and heart stress tests.

Help Kamol describes for patients from abroad. Before you travel, the hospital says a surgeon can see you by video, each consultation request gets its own personal coordinator, and an international telephone line takes questions, including urgent ones. Kamol also helps with hotels and with getting from the airport, and sends patients back to the airport by limousine when they leave. After discharge, recovery can continue at K Garden, serviced apartments that belong to the hospital and sit close by, with the surgeon's follow-up visits there. Extending a medical treatment visa is also something Kamol says it can do. For payment, Kamol lists credit and debit cards, bank transfer, and six cash currencies: baht, euro, US dollar, pound sterling, Australian dollar and Canadian dollar.

Language. Kamol names English and Thai as the languages its staff speak, and it will find an interpreter for another language when a patient requests one. For Dr. Tharatip himself, the Bangkok Hospital profile records English and Thai. Put any interpreter request in your consultation form. During voice rest you will write rather than speak, so settle beforehand how you will communicate with the nurses and the international team.

How long to stay. As general guidance for voice feminization, our voice feminization guide advises staying until the follow-up check at the end of voice rest, commonly around 7 to 10 days in Thailand. Treat that only as a starting point: Dr. Tharatip or the hospital will set your own timeline, and for voice masculinization you should ask for it at the consultation. A flexible return ticket helps, as does a notepad or a phone app for the silent days.

Bangkok Hospital (Headquarters). Our Bangkok Hospital (Headquarters) profile notes that it has an international patient desk. Even so, his page there listed no clinic hours when we looked, and his voice surgery listing comes from Kamol, so a voice surgery request is most practical through Kamol. Our patient team can still enquire at both hospitals.

Planning voice surgery relies more on your voice history than on photographs. Prepare the points below, and send health details only via our own booking form or WhatsApp line rather than through other channels:

• Your goal. Whether you are asking about voice feminization or voice masculinization, and what you want to change: pitch, how your voice is perceived, strain, or something else.
• Hormone history. When you started oestrogen or testosterone, what you take now, and how your voice has changed on it.
• Voice therapy. How many sessions you have had, over what period, and any report or notes from your speech-language therapist.
• Previous assessments. Reports from any earlier examination of your throat or voice by an ENT doctor or voice clinic.
• Previous surgery. Any operation on the neck, throat or vocal folds, including an earlier tracheal shave or voice surgery, with operation notes if you have them.
• General health. Health conditions, breathing problems, medicines, allergies, and whether you smoke or vape.
• How you use your voice. For example singing, teaching, phone work or public speaking, since voice surgery can change range and singing.
• A recording or photos, only if asked. The team may ask for a short voice recording, or for neck photos if you are also considering a tracheal shave. Do not send them unless requested.
• Practical details. Travel dates you are considering, how many days of voice rest and follow-up in Bangkok your schedule allows, whether a video call or a visit in person suits you, and any interpreter you need.
• Your questions. The list from the consultation section above, so they can be answered together.
