Changes in the position of the inferior alveolar nerve after sagittal split ramus osteotomy and its effect on postoperative neurosensory disturbances - 08/12/24
Abstract |
Aim of the study |
To analyze the positional changes of the inferior alveolar nerve after sagittal split ramus osteotomy (SSRO) and assess the impact of these changes on postoperative sensory nerve disturbances.
Material and methods |
Preoperative and postoperative (one year) spiral CT scans were used to categorize the inferior alveolar nerve into the extended side (n = 30) and retrogressive side (n = 30). Measurement software was used to observe and measure positional changes of the mandibular nerve canal, followed by a comparative analysis.
Results |
Post-surgical analysis revealed that the inferior alveolar nerve was displaced laterally and superiorly on the extended side, and medially and inferiorly on the retrogressive side, with statistically significant differences (p < 0.05). Correlation analysis demonstrated a significant association between nerve displacement in the first molar region and sensory nerve impairment (p < 0.05).
Conclusion |
Significant positional changes in the inferior alveolar nerve were observed post-surgery, particularly on the extended migration side, with these changes being correlated with the occurrence of neurological symptoms.
