Abstract
OBJECTIVE: To discuss the clinical application and effectiveness of autologous costal cartilage transplantation in the repair of upper lip depression in the secondary repair of cleft lip. METHODS: The clinical data of 10 patients of secondary repair of upper lip depression with cleft lip by autologous costal cartilage transplantation between January 2017 and January 2019 were retrospectively analysed. There were 7 males and 3 females with an average age of 24 years (range, 18-33 years). There were 8 cases of bilateral lip fissure and 2 cases of unilateral lip fissure. All of them underwent early lip repair at the age of 2-3 years old. The change of the profile of the soft tissue profile of the upper lip of the patient was quantitatively analyzed before operation and at immediate after operation, including the soft tissue facial angle (G-Sn-Pg'), the nasolabial angle (Cm-Sn-UL), the mentolabial angle (UL-LL-Pg'), the distance between the most salient point of the upper lip to the aesthetic plane (UL-E), the highest point of the frontal part, the projection distance of the most salient point of the upper lip on the plane of the orbital ear (G-UL), and the upper lip protrusion (ULP). RESULTS: One case had incision infection and healed after dressing change, and in the other 9 patients, the incisions healed by first intention, and no acute infection and other complications occurred. The appearance of the lateral morphology of the upper lip at immediate after operation was significantly improved when compared with that before operation. The value of UL-LL-Pg', UL-E, G-UL, and ULP were significantly increased and G-Sn-Pg' was significantly decreased when compared with preoperative ones ( P<0.05). There was no significant difference in Cm-Sn-UL between pre- and post-operation ( t=0.821, P=0.433). All the 10 patients were followed up 6-24 months, with an average of 15 months. During the follow-up, the soft tissue morphology of the upper lip was good. No long-term complications such as cartilage absorption and cartilage displacement were found. CONCLUSION: Autologous costal cartilage transplantation is a safe and effective treatment for upper lip depression in the secondary repair of cleft lip.
