Factors Affecting Functional Sensory Recovery After Inferior Alveolar Nerve Repair Using the Nerve Sliding Technique

PurposeThe nerve sliding technique (NST) was introduced for repairing inferior alveolar (IAN) defect and overcoming the disadvantages of conventional surgical treatment methods such as graft. This study conducted to identify factors associated with functional sensory recovery (FSR) following repair using NST.Patients MethodsThis a retrospective cohort including all patients who underwent IAN NST at Seoul National University Dental Hospital, Department Oral Maxillofacial Surgery from February 2009 March 2020. The damaged part excised, incisive branch transected intentionally perform direct anastomosis without tension. Cox proportional hazard analysis utilized determine relationships between predictor variables (age, gender, chief complaints, preoperative results, duration injury repair, length tissue resected during procedure, neuroma formation) outcome variable (time FSR).ResultsThe sample composed 16 mean age 56.1 ± 10.1 years, 25% were males 75% females. gap deficit 7.69 mm (3-15 mm). Ten (62.5%) achieved FSR median time operative 84.5 days. implant placement found main cause (93.8%) 56.2% complained hypoesthesia dysesthesia. Factors 1 year age, complaint, early repair. Younger (P = .041) dysesthesia .019) more likely achieve FSR. Higher proportion group FSR, although not statistically significant .068).ConclusionsThe use in defects up 15 62.5% absence higher NST.
