Objective. Experimental lesions in the inferior alveolar nerve (IAN) are used for the study of peripheral and central alterations. The objective of our study was to contribute to a more precise description of the approach to the IAN and creating a lesion. Material and methods. Twenty-six males of Wistar laboratory rats were used for the study. The animals were divided into three groups: control group (6 rats), experimental group (12 rats - a part of the bone above the mandibular canal was removed under general anaesthesia using extraoral approach, after exposing a part of the IAN, the nerve was excised in a length of 3 mm), and a sham group (8 rats - the nerve was only dissected but not transected). Persisting denervation was verified using surgical revision and histological and immunohistochemical analysis after the observation period (4 weeks). Results. No evidence of re-innervation after 4 weeks. We found no statistically significant differences in mean weight gains between individual groups during the observation period. Conclusion. The described technique used in the study is one of the possible ways to create a nerve lesion at the site of the main trunk of the nerve. At the same time, the study provides a more precise description of the anatomical situation and approach to the IAN in the mandibular canal.
Bilateral sagittal split osteotomy (BSSO) aims to correct congenital or acquired mandibular abnormities. Temporary or permanent neurosensory disturbance is the most frequent complication of BSSO. To evaluate the influence of IAN handling during osteotomy, the authors undertook a prospective study in 290 patients who underwent BSSO. The occurrence and duration of paresthesia was evaluated 4 weeks, 3 months, 6 months, and 1 year after surgery. Paresthesia developed immediately after surgery in almost half of the patients. Most cases of paresthesia resolved within 1 year after surgery. A significantly higher prevalence of paresthesia was observed on the left side. The authors found a correlation between the type of IAN position between the left and right side. The type of split (and IAN exposure) did not have a significant effect on the occurrence or duration of neurosensory disturbance of the IAN. The authors did not find a correlation between the occurrence and duration of paresthesia and the direction of BSSO. Mandibular hypoplasia or mandibular progenia did not represent a predisposition for the development of paresthesia. In the development of IAN paresthesia, the type of IAN exposure and the split is less important than the side on which the split is carried out.
