Introduction: The chin and nasal projection are two important contributory factors in establishing an aesthetically pleasing facial profile. However, conventional sliding genioplasty can produce paraesthesia and a notch at the mandibular lower border. The box genioplasty is an alternative procedure with a reduced complication rate and can be used in combination with other aesthetic procedures including orthognathic surgery.
Methods: A retrospective analysis of 33 patients treated with box genioplasty over a 7-year period was performed (27 females and 6 males). Patients were reviewed post-operatively at 1, 2 and 6 weeks followed by 3 and 12 months. Clinical examination was performed and photographic documentation taken. Sensation was recorded at 12 months. The pre and postoperative facial profiles were studied retrospectively by a second author not involved in the primary surgery.
Results: Sensory deficit and facial profiles of the patients in the study group are presented. 3 patients had persistent neurosensory deficit. All patients showed changes along the labiomental angle and the genial prominence. All patients experienced an improved profile.
Conclusions: The chin position plays a major role in the aesthetics of the lower face. Therefore, box genioplasty provides the opportunity to correct both bony and soft tissue deformities with minimal complication. Our study is a stepping stone for a prospective comparable study of different techniques of genioplasty but also raises the need for anthropometric studies to assess the variation of chin morphology.
