Sažetak
Objective: To prospectively evaluate the incidence of change in light-touch sensation in the innervated area of the lower alveolar nerve after bilateral sagittal-split osteotomy (BSSO) with attention on the time it takes to rebuild the function of the inferior alveolar nerve. Materials and Methods: The sample consisted of 30 women and 20 men with a mean age of 22.14 6 3.30 years. The neurosensory test was conducted with a 20-mm long monofilament of suture material Prolene (3-0) connected to a plastic holder. These tests were performed 1 day before surgery and every 2 weeks during first 2 months after surgery. After that, patients were tested once every month until the end of the first year. Results: All patients had a disturbance of light-touch sensation after BSSO, but none of these changes was permanent. The average duration of hypoesthesia was 6.6 6 1.2 with a range from 4 to 9 months. The average duration of hypoesthesia for women was 6.27 6 1.0 months, and men had hypoesthesia for 7.1 6 1.2 months on average. This difference was statistically significant. The two oldest female patients, who were 33 and 37 years old at the time of the surgery, experienced altered sensitivity for only 4 months. Conclusions: After BSSO, all patients experienced disturbed light-touch sensation in the innervated area of the lower alveolar nerve. A faster ecovery in the oldest patients and a statistically significant difference between the sexes should be interpreted with caution.
