In short. How cleft lip repair is planned and performed, when it is usually done, what the first operation can and cannot achieve, and what recovery and the scar are really like.
Key points
- The first repair closes the lip, rebuilds the muscle, and produces a lip that can seal and move.
- It also reshapes the base of the nose, which the cleft distorts, so that it sits more symmetrically.
- In many children this is the main lip surgery they will ever need.
Cleft lip repair closes the gap in the upper lip and rebuilds the muscle, skin and lining around it. It is usually the first major operation a child with a cleft has, and for many families it is the moment the cleft becomes visible only as a fine scar.
Timing
Most centres repair a cleft lip between about three and six months of age. The interval is not wasted: it lets the baby grow, establish feeding, and be assessed for any other condition needing attention first. Some units use pre-surgical moulding or taping beforehand to bring the lip segments closer together, which can make the repair easier and the scar finer. Prematurity, low weight, or feeding difficulty can all move the operation later, and that is a deliberate decision rather than a delay.
What the operation involves
Under general anaesthesia the surgeon makes planned cuts along the edges of the cleft, brings the three layers of the lip, the inner lining, the muscle and the skin, into alignment, and closes them in layers. Rebuilding the muscle ring matters most functionally, because it is what allows the lip to seal around a spoon or a cup and to form sounds. The skin is then closed with fine sutures placed along natural lines.
What the first operation achieves
Closure, function, and a foundation
The first repair closes the lip, rebuilds the muscle, and produces a lip that can seal and move. It also reshapes the base of the nose, which the cleft distorts, so that it sits more symmetrically. In many children this is the main lip surgery they will ever need. What it provides is a foundation: a mouth that can feed and form sounds, and a face that no longer announces the cleft at a glance.
What it does not achieve
It does not remove the cleft from the record. A scar remains and is permanent; it fades over a year or more but does not disappear. The lip may be slightly asymmetric. The nose often stays flatter or wider on the cleft side, because the cartilage and bone beneath are also affected. The gum may still need bone grafting later, and a cleft palate is repaired separately. None of this means the operation failed. It means the cleft was never only a skin problem.
Recovery and later refinement
Most children stay in hospital for a few nights. Feeding usually resumes quickly, sometimes with a specialist feeder rather than direct breastfeeding for a short period. Sutures may be dissolvable or removed at five to seven days. The lip is swollen and the scar red for some weeks, then settles gradually. Some children later benefit from a second, smaller operation to refine the scar or the nose, considered only after the face has grown substantially.
Seek care urgently if
- Your child has difficulty breathing or pauses in breathing after the operation.
- There is bleeding from the repair that does not stop with gentle pressure.
- The repair site becomes red, hot or swollen, starts discharging, or your child develops a fever.
Frequently asked questions
When is cleft lip repair performed?
Most centres repair a cleft lip between about three and six months of age. The interval lets the baby grow, establish feeding, and be assessed for anything needing attention first. Some units use pre-surgical moulding or taping beforehand to bring the lip segments closer, which can make the repair easier and the scar finer.
What does cleft lip repair achieve?
It closes the lip, rebuilds the muscle ring so the lip can seal around a spoon or cup and form sounds, and reshapes the base of the nose, which the cleft distorts. In many children this is the main lip surgery they will ever need. It gives a foundation rather than a perfect result.
Will the lip scar disappear?
No. A scar remains and is permanent; it fades over a year or more but does not disappear. The lip may be slightly asymmetric, and the nose often stays flatter or wider on the cleft side, because the cartilage and bone beneath are also affected. The gum may still need bone grafting later.
Risks & Limitations
- Cleft care spans years and usually several operations. A single procedure does not finish it, and the plan may change as a child grows.
- Scars from lip and nasal repair are permanent. They fade and soften, but they never disappear.
- Speech may still need therapy, or further surgery for velopharyngeal insufficiency, after palate repair.
- Hearing problems and repeated ear infections are common, and may need ventilation tubes and long-term ear review.
- Feeding difficulties before and after repair, including slow feeds and poor weight gain.
- Dental and orthodontic problems: missing, misplaced or crowded teeth, and a bite that needs years of treatment.
- Growth disturbance of the upper jaw, which may require later revision or corrective jaw surgery.
- No outcome is guaranteed. Perfection is not achievable and is not the goal.
When to Seek Care
- A baby who cannot feed, coughs or chokes during feeds, or is losing weight or not gaining it.
- Difficulty breathing, noisy breathing, or pauses in breathing, especially after palate repair.
- Fever with a repair site that is red, hot, swollen or discharging.
- Bleeding from a lip or palate repair that does not stop with gentle pressure.
- Fluid or discharge from the ear with pain or fever, or any suspected change in hearing.
