Approach to Half-Nose and Proboscis Lateralis

Half-nose or heminasal aplasia is an extremely rare congenital malformation, which has a withering effect both on the patient and the family. Proboscis lateralis is a rare facial anomaly resulting in the incomplete development of one side of the nose, which was first defined in 1861 by Forster in his monograph. Proboscis lateralis, cleft nose, and nasal agenesis are rare anomalies; however, half-nose is also an extremely rare condition. In the formation of half-nose deformities, either a facial cleft or nasal dysplasia is the assumed theories of embryological origin. In the reconstruction of proboscis lateralis tissue, local flaps and forehead flaps can be used for a functional and esthetically acceptable structure. The expanded forehead flap has become commonly used in recent years. Estimating the cosmetic result of surgery is an extreme challenge because of the accompanying nasal growth of the transferred tissue and the nose. In this study, the authors report on the reconstruction of half-nose and proboscis lateralis deformity with clinical results.
