When to Repair, and Why the Calendar Matters
Why is the lip usually repaired at about three months and the at about nine to twelve months, and what is being balanced in that choice?
💡 surgery timing is a deliberate balance of , speech, and growth, not a single fixed date.
Prerequisite check
- Job 1 is closing the in layers; Job 2 (the harder one) is rebuilding the into a working sling.
- In a the levator ran the wrong way and inserted onto the back of the ; imaging shows it stays abnormal even after repair, worst in children who still leak air.
What you will learn
Goal: Explain why lip repair happens at about 3 months and repair at about 9 to 12 months, and justify the timing as a balance between , growth, and speech development.
- Lip repair is usually done at about 3 to 6 months; repair is generally favored as a one-stage repair at about 9 to 14 months, before first words.
- Three forces pull on the dates: (wait for the infant to grow for safer anesthesia), speech (the valve must work before first words), and growth ( surgery disturbs upper-jaw growth, pulling toward waiting).
- Earlier repair within the usual window supports better speech; a large study found older age at worsened outcomes.
- Timing is not only biology: in some settings minority and non-English-speaking children reached surgery measurably later, a non-anatomical cause of delay.
Model: The usual schedule and the forces pulling on it
Two repairs, two target ages. Lip repair: about 3 to 6 months of age. repair: generally favored as a one-stage repair at about 9 to 14 months, before a child's first real words. Three forces pull on these dates. : a newborn is small, and anesthesia is safer once an infant has grown; surgeons historically used a as a readiness guide (around 10 weeks old, 10 pounds, and a healthy blood count) before lip repair. Speech: the palate must work before a child starts forming words, because the velopharyngeal valve shapes speech sounds from the start, so closing the palate too late means practicing speech with a broken valve. Growth: operating on the palate disturbs upper-jaw growth, which pulls toward waiting, but waiting hurts speech, so timing is the compromise.
The evidence gives a clear direction. One-stage repair is generally favored at about 10 to 14 months, and delay is associated with significant speech deficits. In a 1254-patient study, older age at worsened outcomes. And in some US settings, minority and non-English-speaking children reached surgery measurably later than others, a non-anatomical cause of delay. The pattern: earlier palate repair within the usual window supports better speech, growth is the reason not to operate even earlier, and access problems can push the date later than anyone intends.
Explore (work the model before reading on)
- Write the usual target age for lip repair and for repair.
- Name the three forces pulling on the timing of repair.
- Speech pulls toward repairing the earlier and growth pulls toward later. Explain why the usual window sits between them rather than at either extreme.
- Using and speech, explain why the lip can go first and earlier while the waits until closer to the first birthday.
- Some children reach surgery later for reasons unrelated to . Predict one thing a team could do to keep timing on track for a family facing those barriers.

- Read the Model and answered the Explore questions.
- Filled in the guided notes in my own words.
- Defined the new vocabulary with an example.
- Built the producible: Set Mateo's surgical calendar for the family in four sentences: (1) state the target age for his lip and palate repairs, (2) justify the palate date using both the speech force and the growth force with a source, (3) name one non-anatomical thing that could push his date later and one way the team will guard against it with the disparity source, and (4) end with two committed dates, not a hedge.
- Wrote my Claim, Evidence, and Reasoning exit ticket.
Exit ticket (Claim, Evidence, Reasoning)
- Claim: surgery timing is a compromise, not a single right date.
- Evidence: Cite the speech-delay finding and the older-age finding with sources.
- Reasoning: Explain why repairing the lip early and the near the first birthday serves Mateo better than doing both at once.

Where this leads: careers
What's next: We set Mateo's calendar: his lip repaired around three months, his before his first words land. We argued that the timing itself helps protect his speech. But that rests on a claim we have not proven. Why does closing the roof of the mouth matter so much for talking in the first place? We chase that next time.
