Abstract

Patients with unilateral cleft lip and palate (UCLP) generally demonstrate the asymmetries in the lip, nose and the naso-maxillary complex. And their skeletal asymmetries are known to be derived from the displacement of nasal septum, anterior nasal spine (ANS) and the pre-maxilla toward the non-affected side during the developmental and growth period. Due to the interruption of the important facial muscles, which are critical for the symmetric growth of premaxilla, functional matrix system fails to develop and results in the displacement of the ANS toward the non-affected side and nasal asymmetry. Therefore the rhinoplasty for CLP patients is required to have inter-skeletal and muscular rearrangement in the naso-maxillary complex in order to let them recover from esthetic and physiologic imbalances. And functional cheilorhinoplasty (FCR) has been a representative treatment of choice for this concept of treatment modality. The outcome and prognosis of primary or repair FCR have been known to be definitely affected by timing of the operation as well as adequate reconstruction of naso-labial muscles. However, sometimes FCR has an ineffective treatment results for patients after the facial growth period, and the limited rhinoplasty around the nose often fails to bring satisfying results. In order to circumvent this limitation, we performed ANS osteotomy for patients with unilateral CLP showing asymmetric nose, as an alternative way for corrective rhinoplasty. We could observe that the nose was rearranged along the facial mid-line by this osteotomy design and asymmetries were evidently improved postoperatively. Here we present this osteotomy method in CLP patients.
