Neurosensory disturbance (NSD) is a common complication after mandibular orthognathic surgery, mandi-bular posterior teeth implant surgery and mandibularthird molar extraction. Although in most cases the incidence is low, some patients suffer fromobvious discomfortin a long term. Clinicians and patients have paid great attention to this pro-blem. NSD of the inferior alveolar is often manifested as hypoesthesia and abnormal sensation, and sometimes hyperesthesia of the chin and lips on the surgical side, as well as discomfort of the mandibular dentition on the affected side. Most patients can recovery within 6 months after the occurrence of NSD, whereas a small number of patients were reported failed to recover from disturbance after 6 months or even longer. This article attempts to review symptoms and prognostic characteristics during NSD of the inferior alveolar nerve after different types of operations, and try to analyze the differences and correlations among them.

Key words: inferior alveolar nerve, neurosensory disturbance, orthognathic surgery, tooth implant surgery, third molar
