Abstract

Background: Previous studies of the inferior alveolar nerve have used cadaveric specimens in small patient groups. The purpose of this study was to describe the anatomy in the posterior mandible with respect to the inferior alveolar nerve (IAN) using computed tomography (CT) images in a large patient population. We hypothesize that CT scans are an important component of a thorough treatment plan for minimizing risk to the IAN and optimizing surgical outcomes. Methods: CT scans of 195 patients (62 males and 133 females; age range: 22 to 88 years) were evaluated retrospectively. With the aid of computer software, cross-sectional images were examined at 5-mmincrements distal to the mental foramen to the ascending ramus. Four measurements were made at each cross-sectional image. The distances from the IAN to the: 1) alveolar crest (CN); 2) buccal cortical plate (BN); 3) lingual cortical plate (LN); and 4) inferior border (IN) were measured. Results: Most measurements for males and females were significantly different. Mean values were as follows (males/females): CN, 13.85 ±0.43/11.98 ±0.40 mm (P
