Abstract:

During orthognathic surgery, there is risk of damage to maxillary and/or mandibular branches of the trigeminal nerve (CNV) which supplies the sensation to the face. These branches may be inadvertently compressed, retracted or transected during subperiosteal dissection causing potential disturbance in signal transmission, with resulting paraesthesia. At Cumberland Infirmary an audit was used to assess paraesthesia immediately post-surgery, paraesthesia following a recovery period and to assess the most common areas affected by paraesthesia in post-orthognathic surgery patients. Average time of sensation recovery and the effect of paraesthesia on the quality of life were also investigated. Using a specifically designed questionnaire to assess paraesthesia via selfreport, retrospective data was collected from a number of post-orthognathic surgery patients. Patients ranged from having surgery 6 months to 8 years previously, 19 to 45 years of age. Comparison of the collected data and that found in the literature was executed, to see whether the level of paraesthesia following orthognathic surgery in Cumbria was high, low or average. Following analysis, several changes were implemented to instigate reduction in permanent nerve damage. Results were also utilized for the consenting process, to provide patient information regarding paraesthesia subsequent to orthognathic surgery.
