Abstract
This study determined whether immediate reconstruction of the inferior alveolar nerve with a long (>4.5 cm) processed nerve allograft (PNA) in conjunction with simultaneous ablation and reconstruction of the mandible would be effective in safely restoring subjective sensation and achieving functional sensory recovery. Patients (5 to 70 yr old) requiring resection of the unilateral or bilateral mandible for benign pathology were included. The graft had to be longer than 4.5 cm. Results of sensory nerve tests and 3 different surveys (Direct Path, Numerical Rating Scale, Word Choice) were collected before surgery and at 3, 6, and 12 months after surgery. Safety data were recorded. Twenty-six patients participated in this study. Three patients served as positive controls (no nerve repair). Five in the repair group and 1 in the positive control group were lost to follow-up. Data during a 1-year period were collected on 18 patients (7 male and 11 female; mean age, 26.4 yr; range, 10 to 64 yr). The mean length of the PNA was 62.7 mm (range, 45 to 70 mm). Seventeen of 18 patients had S4 sensory scores preoperatively and the postoperative score was S4 at 3 months in 3, at 6 months in 3, and at 1 year in 12. Scores for positive control p...Continue Reading
