What a cleft is
A cleft lip or cleft palate occurs when the tissues forming the upper lip or the roof of the mouth do not fully join during early pregnancy. It is one of the most common congenital differences worldwide, and it is nobody's fault — in the great majority of cases there is nothing a parent did or failed to do.
A cleft may involve the lip only, the palate only, or both, and may affect one side or both. Beyond appearance, a cleft can affect feeding, speech, hearing, dental development and facial growth, which is why treatment is staged over years rather than settled in a single operation.
Dr Kueh's background in cleft care
Dr Kueh completed his plastic surgery training at Chang Gung Memorial Hospital in Taiwan, an institution internationally recognised for craniofacial and cleft surgery. Reconstructive work of this kind remains a core part of his practice in Kuching, and he sees children referred by paediatricians, general practitioners and hospital colleagues across Sarawak.
Timing of surgery
Timing balances the benefit of early repair against the child's size, weight and safety under anaesthesia. The plan is individual, but as a general guide:
- Cleft lip repair is usually carried out at around three to six months of age.
- Cleft palate repair is usually carried out at around nine to eighteen months, timed to support normal speech development.
- Alveolar bone grafting, where the cleft involves the gum, is typically done between around eight and twelve years, guided by dental development.
- Further procedures — speech surgery, lip or nose revision, or jaw surgery — may be considered later, as growth completes.
Before lip repair, some babies benefit from pre-surgical measures such as taping or nasoalveolar moulding to narrow the gap and improve the eventual result.
What the operations involve
Cleft lip repair (cheiloplasty)
The lip is reconstructed in layers — skin, muscle and inner lining — so that the circular muscle of the mouth is continuous and functions properly. The position of the nostril on the affected side is usually improved at the same time. A scar remains along the line of repair, following the natural contour of the lip.
Cleft palate repair (palatoplasty)
The roof of the mouth is closed and, importantly, the muscles of the soft palate are repositioned so they can work correctly. This is what allows the palate to separate the mouth from the nose during speech. The aim is not only closure but function.
Care is a team effort
Surgery is one part of cleft care. Children generally also need input from speech and language therapy, dentistry and orthodontics, ENT and audiology (glue ear and hearing loss are common with cleft palate), paediatrics, and feeding support in infancy.
Where a child needs services the clinic does not provide directly, we will help you connect with them rather than leave you to work it out alone.
Feeding and the early weeks
Babies with a cleft palate often cannot generate suction, so specialised bottles and teats are used. Adequate weight gain before surgery matters, and feeding support is arranged early where needed.
After surgery your child will be on a guided feeding plan, usually liquids or soft food initially. Arm splints are sometimes used briefly to stop little hands reaching the repair. Most children recover more quickly than parents expect.
Risks and what to expect long term
Risks include bleeding, infection, wound breakdown, and occasionally a fistula — a small gap that reopens after palate repair — which may need a further operation. Anaesthetic risk in infants is discussed fully with the anaesthetist beforehand.
A scar is permanent, though it typically softens and fades considerably over the first year or two. Some children go on to need additional surgery for speech, for the appearance of the lip or nose, or for jaw position as they grow. This is a normal part of cleft care rather than a sign that anything went wrong.
With appropriate treatment, children born with a cleft go on to eat, speak and grow normally. The pathway is long, and we will be honest with you at each stage about what comes next.

Cleft Repair FAQ
When should my baby have cleft surgery?
Cleft lip repair is usually carried out at around three to six months of age, and cleft palate repair at around nine to eighteen months. Exact timing depends on your baby’s weight, general health and the specific anatomy of the cleft.
The plan is set individually after examination, not by a fixed schedule.
Will my child need more than one operation?
Often, yes. Cleft care is staged across childhood. Beyond the initial lip and palate repairs, a child may need alveolar bone grafting around eight to twelve years, speech surgery, revision of the lip or nose, and occasionally jaw surgery once growth is complete.
This is expected and planned for, not a sign that earlier surgery failed.
Will my child speak normally?
Many children go on to develop normal speech, particularly when palate repair is well timed and speech therapy is provided. Some need additional speech surgery if the palate does not close off the nose adequately during speech.
Speech and language therapy is an essential part of care and should not be regarded as optional.
How noticeable will the scar be?
A scar along the line of repair is permanent, but it is placed to follow the natural contours of the lip and typically softens and fades substantially over the first year or two. Scar care, sun protection and massage are advised, and revision can be considered later if needed.
Is cleft surgery covered by insurance?
Cleft repair is reconstructive surgery performed for a medical reason, and is frequently covered by medical insurance, unlike cosmetic procedures. Coverage depends on your policy and on whether the condition is regarded as congenital under its terms. Our team can provide the documentation your insurer requires.
Do I need a referral to be seen?
No referral is needed, though referrals from paediatricians, general practitioners and hospital colleagues are welcome. If your child has already been seen elsewhere, please bring any letters, imaging or operation notes to the first appointment.
