Evolution of sensory recovery following mandibular bilateral sagittal split osteotomy

Conclusiones: Los sujetos estudiados alcanzaron una recuperación de la sensibilidad clasificada como hipoestesia moderada al primer año postoperatorio. El género femenino alcanzó mayores valores de recuperación (83 vs. 69%) y en un menor tiempo que el género masculino. Des tacamos el uso de 3 métodos de evaluación que nos permiten comparar lo objetivo y subjetivo, obteniendo resultados concordantes entre sí.Abstract Introduction: Bilateral sagittal split osteotomy is one of the most common surgical procedures performed during orthognathic surgery. Postoperative reports have described neurosensory changes related to the inferior alveolar nerve. Paresthesia has been described in relation to its damage ranging between 12.5 and 100%. The aim of this study was to determine the percentage of sensitive recovery in the compromised area after bilateral sagital split osteotomy during the first postoperative year. Method: The study included 32 patients with class II and class III dentofacial deformity. Surgical procedure must include bilateral sagittal split osteotomy. Follow-up was performed at 1st, 3rd, 6th, 9th and 12th postoperative months. The evaluated area was determined by a novel technique that consists in dividing the chin in squares of 8 equal parts. Sensorial recovery was tested using calibrated von Frey monofilaments. Results are displayed in relation to the studied area, gender, skeletal class and surgical technique. Statistical significance was accepted with a ...
