Dr. Penpak Krergmatukorn

Dr. Penpak Krergmatukorn (Thai: พญ. เพ็ญพักตร์ เกริกมธุกร) practises plastic surgery in Bangkok. Her published record spans cosmetic and reconstructive work, with a clear thread of craniofacial and children’s surgery running through it. Bumrungrad International Hospital lists her in its Plastic Surgery Center and gives her specialty as Plastic Cosmetic & Reconstructive Surgery. Separately, she is an attending physician at a state-run paediatric hospital, Queen Sirikit National Institute of Child Health (QSNICH), whose Plastic Surgery Clinic lists her among its doctors.

On Bumrungrad’s website her special clinical interests fall under two headings. The craniofacial surgery heading names cleft care and facial trauma. The cosmetic surgery heading names five areas:

• eyelid surgery (blepharoplasty)
• breast surgery
• scar management
• skin tumour removal
• paediatric soft tissue surgery

Only the first of these has a matching procedure guide on ThaiCosmeticSurgery.com, which is why blepharoplasty is the one procedure attached to her profile. The remaining headings are genuine parts of her published practice, yet the hospital does not translate them into named operations, and we have not filled that gap with guesses. Further down this page you will find questions that turn a broad heading into a specific answer for your own case.

Her published training begins with a 1993 medical degree from Chiang Mai University, continues with Thai board diplomas in surgery (1997) and plastic surgery (1999), and includes a 2008–2009 craniofacial fellowship at Chang Gung Memorial Hospital in Taipei. Thai, English and Mandarin are the languages Bumrungrad shows for her.

Patients who want an appointment at Bumrungrad can send a consultation request for Dr. Penpak Krergmatukorn. Our patient team asks the hospital about her clinic slots first and only then agrees a date with you, so sending the form does not by itself reserve an appointment.

The qualifications below are the ones Bumrungrad International Hospital publishes on her profile, arranged by year:

• 1993, medical degree: M.D. (แพทยศาสตรบัณฑิต), awarded by Chiang Mai University (Faculty of Medicine) in northern Thailand
• 1997, surgery board: Thai Board of Surgery diploma (Thai title วุฒิบัตร สาขาศัลยศาสตร์)
• 1999, plastic surgery board: Thai Board of Plastic Surgery diploma
• 2008–2009, fellowship: Craniofacial Surgery, Chang Gung Memorial Hospital, Taipei, Taiwan

What the board diplomas mean. Speaking generally, the Thai term วุฒิบัตร refers to a specialist diploma awarded once a doctor finishes a recognised specialty training programme in Thailand. Dr. Penpak’s two diplomas are two years apart: general surgery first, then plastic surgery.

Chulalongkorn University alumni listing. Her name is in the alumni directory of CUPS, the plastic and reconstructive surgery division of Chulalongkorn University’s Faculty of Medicine, under class 15 (รุ่นที่ 15). Because that page gives neither a year nor a description of the programme, we treat it only as evidence that the division counts her among its alumni, not as proof of a particular residency.

Why the Taipei fellowship matters to her profile. Craniofacial surgery deals with the bones and soft tissues of the skull and face, including cleft lip and palate and fractures of the facial skeleton. Her fellowship year at Chang Gung Memorial Hospital lines up with the rest of her record: the craniofacial heading on her Bumrungrad profile names cleft care and facial trauma, and related conditions appear on the list of problems seen at the children’s hospital clinic where she holds a weekly session.

Research. A PubMed search for her surname returns a single paper, “The Trend of Cleft Care at a Children’s Referral Center in Thailand”, in *The Cleft Palate-Craniofacial Journal* (2020). On that paper she is affiliated with the Department of Plastic Surgery at QSNICH, the children’s hospital where she holds her weekly clinic.

Society listings. In November 2019 ThPRS put a member entry for her online. It records her address as QSNICH, the children’s institute on Ratchawithi Road, and shows medical licence number 18816. Before that, surgery.or.th, the website of the Thai aesthetic plastic surgery society (ThSAPS), carried a directory entry for her; it was last edited in 2017 and gave Bumrungrad and the children’s hospital plastic surgery unit as her practice locations. The society’s site no longer carries that directory, and our search turned up no current public ThSAPS member list, so her ThSAPS listing can be confirmed only from archived snapshots taken in 2019 and 2020.

Licence verification. 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 number 18816 is therefore taken from her ThPRS entry and has not yet been matched against the Council’s own record; you can search the register yourself. The provider research methodology page describes how we collect and check facts like these.

Two current posts are documented for Dr. Penpak: a clinic in a private hospital, Bumrungrad, and a weekly clinic in a public children’s hospital.

Plastic Surgery Center, Bumrungrad International Hospital. Her name appears on the doctor list of Bumrungrad’s Plastic (Cosmetic) Surgery Center, found on Building A’s 16th floor. Her outpatient hours, as listed on the day of our review (27 September 2026), were:

• Wednesday evening, 17:00–20:00
• Sunday afternoon, 13:00–16:00

These hours are set by the hospital and can change; our patient team checks the current timetable after you send a consultation request. The centre sees doctors’ patients by appointment only. Among its published services are cosmetic operations for both men and women, and a reconstructive list naming paediatric reconstruction, facial bone reconstruction and maxillofacial reconstruction, areas that sit close to the craniofacial interests on her own profile.

Children’s plastic surgery clinic, Queen Sirikit National Institute of Child Health. This Bangkok institute (สถาบันสุขภาพเด็กแห่งชาติมหาราชินี) lists her as one of the attending physicians (แพทย์ประจำ) of its Plastic Surgery Clinic, with Thursday given as her clinic day. According to the clinic’s page, the children it sees include those with:

• congenital differences of the face and skull, for example cleft lip and palate
• skin lesions on the face
• vascular malformations
• complex wounds and contractures after burns
• possible fractures of the facial bones

That work is reconstructive care for children, not cosmetic surgery, and the institute is not among the cosmetic surgery providers featured on our site.

A long-standing pairing. Her two workplaces are not a recent combination. The ThSAPS directory entry last edited in 2017 already gave both Bumrungrad and the children’s hospital plastic surgery unit, and the 2019 ThPRS entry uses the children’s institute as her address.

Anywhere else? We found no listing for her at any other hospital or clinic. Doctor directories at several other Bangkok private hospitals returned no profile under her name, but that search could not cover every hospital, so further practice locations remain possible.

Every heading in this section is taken from the special clinical interests on Dr. Penpak’s Bumrungrad profile. Where our site has a matching procedure guide we link to it. Where the text moves to general guidance, it describes what patients commonly discuss with a plastic surgeon; it is not a description of her own technique or results.

Eyelid surgery (blepharoplasty)

Bumrungrad’s wording is simply “eyelid surgery”. It does not specify upper lids, lower lids, crease (double eyelid) surgery or ptosis repair, so her profile cannot tell you which of these she offers. Name the exact operation in your request and ask the hospital to confirm it.

As general background, blepharoplasty is surgery that takes away or moves excess skin, muscle and fat around the eyelids. The main variants covered on our site are:

• upper eyelid surgery, aimed at hooding of the upper lid; in some patients a heavy upper lid also narrows the top of the visual field, and surgery may improve that
• lower eyelid surgery, aimed at puffiness from under-eye fat, which can be reduced or moved
• double eyelid surgery, which creates a fold in the upper lid where none exists, or reshapes one that does, using either an incision or sutures

If the edge of the upper lid itself droops, the diagnosis is ptosis, a separate condition corrected by repairing the lifting muscle; surgeons look for it before planning cosmetic eyelid surgery. Expect questions about your vision and about dry eye, glaucoma or thyroid eye disease, because any of these can alter what is safe for you.

Our blepharoplasty guide gives general figures rather than figures for any one surgeon. Many patients have it with a local anaesthetic plus sedation, some under general anaesthesia, and most go home the same day. Stitch removal usually falls at around 5–7 days, and most bruising fades over 1–2 weeks. Reported complications include dry or irritated eyes, asymmetry, incomplete eye closure and a lower lid that pulls downward. Loss of vision or severe pain after the operation calls for urgent medical help. Whether eyelid surgery suits you, and in which form, can only be decided after an examination.

Breast surgery

On her profile, breast surgery is a heading without a list of operations. The Plastic Surgery Center where she works lists cosmetic breast reduction, breast lift and breast augmentation, plus breast reconstruction on its reconstructive side. None of that tells you which of these Dr. Penpak herself performs, so put the specific breast procedure in your request and let the hospital confirm whether it is within her practice.

Scar management

This heading covers the assessment and treatment of scars from injuries, burns or earlier operations; our site does not have a separate guide for it. Speaking generally, a scar goes on maturing for months, and whether revision surgery or another approach makes sense depends on how old the scar is, where it lies and what caused it. Useful questions are whether your scar has settled enough to treat, what degree of change is realistic, and what the scar left by any revision would look like.

Skin tumour removal

This means cutting out lumps and lesions in or just beneath the skin. It appears among her Bumrungrad interests, and facial skin lesions are on the list of conditions seen at her children’s clinic. Removal is a medical decision taken after the lesion has been examined. Ask whether the tissue will go to a laboratory for analysis, how the wound will be closed if it is on the face or another visible area, and how and when you will hear the result.

Paediatric soft tissue surgery

Bumrungrad includes paediatric soft tissue surgery in her interests, and her public-hospital post is itself in a children’s plastic surgery clinic. When a child might need an operation, for a skin lesion, a vascular malformation or tightness after a burn for instance, parents typically want to know the age the surgeon suggests for surgery, the kind of anaesthesia a child of that age would have, and how follow-up works for a family living outside Thailand.

Cleft lip and palate, and facial trauma (craniofacial surgery)

These two are the craniofacial interests named on her Bumrungrad profile. They connect to her 2008–2009 fellowship in Taipei, to the conditions listed for her Thursday children’s clinic, and to her one PubMed-indexed paper, which examined cleft care at a Thai children’s referral centre. In general, cleft treatment is staged across childhood and shared with other specialists such as speech therapists and orthodontists, so families should ask who leads the overall plan and when each stage is expected.

Recent facial injuries are a separate matter. If a facial fracture is suspected, go straight to the nearest emergency department; a booking platform is not the right route for urgent care.

The first appointment is where Dr. Penpak examines you, judges whether an operation is suitable and sets out the options; no surgical plan exists before then. Since much of her public profile is written in broad categories such as “eyelid surgery” and “breast surgery”, the questions that help most are precise ones:

• What operation would she recommend? Ask her to name it (upper lid, lower lid or crease surgery, for example) and to explain why it fits your eyes.
• Is the eyelid really the problem? With heavy upper lids, ask whether a drooping lid margin (ptosis) or a low brow plays a part. If a lowered brow is part of the heaviness, a brow lift can sometimes be a better answer than eyelid surgery on its own, a point our eyelid surgery guide also makes.
• How much of this does she do? Neither Bumrungrad nor any other source we found publishes case numbers or outcome data for her. Ask her directly how regularly she performs the procedure you want, and whether the hospital can share examples of her own results.
• Anaesthesia and discharge. Ask whether she would plan sedation with a local anaesthetic or put you fully to sleep, and whether you would leave the hospital the same day.
• Fitting around a Wednesday and Sunday clinic. Her listed Bumrungrad sessions are on Wednesday evening and Sunday afternoon. Ask how the consultation, the operation and stitch removal would be sequenced, and who would see you if a check-up lands on another day of the week.
• Scars and skin lesions. Ask whether it is better to wait, how the wound will be closed and, for any lesion, whether it will be analysed in a laboratory and how you receive the report.
• Surgery for a child. Ask what age she considers right, what anaesthesia is involved, which other specialists join the team and how follow-up is handled for a family abroad.
• Aftercare once you are home. Ask who deals with a concern that appears after you have left Thailand, and which documents you should carry home. Bumrungrad’s Medical Coordination Office names medical reports and fit-to-fly paperwork among the services it provides after discharge.
• What an estimate covers. A price given before she has examined you can only be provisional. Check whether it includes anaesthesia, any overnight stay, follow-up appointments and stitch removal.

She will have questions for you too: your medical history, current medicines and allergies and, for eyelid surgery, any eye problems. Preparing these in advance, using the list in the final section below, makes the visit more productive.

On her Bumrungrad profile, Dr. Penpak’s languages are Thai, English and Mandarin. If none of those is your first language, Bumrungrad says it employs more than 130 interpreters. Cultural Support Officers are a further service Bumrungrad lists for travellers who do not want to rely on English.

Overseas patients can use several services the hospital describes on its website:

• Medical Coordination Office (10th floor, Building A): free of charge; before you travel, its coordination physicians and nurses can go through your records, estimate prices and arrange appointments or telemedicine, and after discharge they issue medical reports and fit-to-fly documents.
• Arrival at Suvarnabhumi: look for the Bumrungrad desk at Gate 9, Exit C, in the airport’s international arrivals area (open 07.00–23.00 daily). The hospital also runs a complimentary hourly van to the hospital and nearby hotels, though departures depend on how many passengers are waiting.
• Local transport: from BTS Nana or BTS Phrom Phong on the Skytrain, a free Bumrungrad shuttle van can take you to the hospital, seven days a week. Its postal address is No. 33, Soi Nana Nua (Sukhumvit 3), Watthana, Bangkok 10110.
• Visas and travel bookings: if you need to stay on, the hospital’s Business Center can arrange a visa extension for you and a companion, working with the Bangkok Immigration Office, and can also reserve hotels and flights.
• Online first visit: the Plastic Surgery Center’s service list includes doctor tele-consultations. Ask us to find out whether Dr. Penpak herself holds first appointments online.

Hospital accreditation. Checked in the accreditors’ own directories, Bumrungrad holds Joint Commission International (JCI) Hospital Program accreditation, first granted with effect from 2002, and HA Thailand’s Advanced Hospital Accreditation, which runs to 22 May 2029.

Planning the length of your trip. For eyelid surgery, our procedure page suggests a trip of roughly 5–7 days as general guidance, which normally leaves time to have the stitches taken out and the healing reviewed before you fly home. Her Bumrungrad sessions fall on Wednesdays and Sundays, so have the hospital confirm consultation, surgery and follow-up dates before you pay for flights, and prefer a ticket whose return date can move: only the operating surgeon can say when flying is safe for you. For the other areas on her profile, the time needed depends on the operation itself, so raise it when you send your request.

Giving the hospital the right details early helps it confirm that your concern is one Dr. Penpak handles, and makes the first appointment more useful. Send anything medical through our site’s booking form or by WhatsApp to our patient team, and let photos wait until her team requests them.
