Abstract

Abstract:

BACKGROUND: Alveolar bone grafting is known to reduce nasal asymmetry by supporting a defective alar base and a sunken nostril. However, there are no studies on details of changes in the upper lip with appropriate measurements.
OBJECTIVE: To measure the change in the upper lip height and nostril sill after alveolar bone grafting.
METHODS: Forty-six congenital unilateral cleft lip and alveolus (UCLA) patients (mean age 9.85 years). The patients underwent alveolar bone grafting with autogenous iliac bone grafts. The average bone graft volume was 2.98 cm3. Photographs of the frontal, lateral and basal views were obtained using standardized photographic techniques. The fixed position points on the patients’ faces were measured. Preoperative and postoperative upper lip height and projection, the proportion indexes of the nostril sill were compared.
RESULTS AND CONCLUSION: The 6-month follow-up results showed that the height of the upper lip was increased, but no significant difference was found. The projection of the upper lip was more prominent, but there was not statistically significant difference bbetween pre- and post-operation. The nostril sill was significantly elevated in three of four distance items. In conclusion, the height of the upper lip is elongated and the nostril sill is elevated after alveolar bone grafting in UCLA patients.
