TRIGEMINAL NERVE INJURIES

Reduction of Inferior alveolar nerve injury in bilateral sagittal split osteotomy (BSSO)

 

 

 

 

A bilateral sagittal split osteotomy (BSSO) is a type of jaw surgery in which the lower jaw (mandible) is split bilaterally (moved forward or backward) to straighten it to a more balanced and functional position. It is performed to correct types of malocclusion, a misalignment of teeth. Injury to the inferior alveolar nerve (IAN) with possible sensory impairment is an important complication of this surgery. The impact of altered sensation in the lower lip after SSO varies from patient to patient. In some patients injury not only gives rise to unpleasant sensations, but may also affect the ability to talk and masticate effectively without traumatizing the affected area. Neuropathic pain following iatrogenic damage of the inferior alveolar nerve (IAN) is a disabling condition that interferes with speaking, eating, drinking, kissing, shaving, applying make-up, and tooth brushing. Despite the risk of IAN injury in BSSO, the treatment benefits are considered to outweigh the treatment drawbacks. With cone beam computed tomography, the course of the nerve and its relationship to the surrounding structures can be assessed in three dimensions. If a schema exist that indicate possible safe distances of IAN at different locations of surgery as well as the magnitude of operation (advancement or setback) that relate with damage to nerve in the mandible during BSSO, problems associated with nerve damage will be highly reduced.
