Correction of macrostomia is based on the principles of cleft lip repair. The commissure of the mouth (the corner of the mouth) is recreated at the same distance from the midline as the normal side. The scar is broken up with z-plasties and the muscle repaired to provide good function.
Apply ice packs (may be effective in a short term to minimize edema).
The sterile dressing placed over the incisions is maintained for a minimum of 48 hours. Thereafter routine wound care should be instituted.
Antibiotic prophylaxis is continued for 1-5 days depending on the nature, complexity, and duration of the surgical procedure.
Remove sutures from skin after approximately 5 days if nonresorbable sutures have been used.
Regular follow up examinations to monitor healing are required.
Avoid sun exposure and tanning to skin incisions for several months.
