Assessment of Genial Tubercle with CBCT with Clinical Relevance

Introduction: CBCT uses have been expanded in many field of medical sciences. In the same way, it can be used to assess the position and anatomy of the genial tubercle during the management of OSA. The present study was planned to assess the utility and accuracy of the 3 D cone beam CT in locating the exact anatomical position of genial tubercle in the human skull. Materials and Method: For the present study, 20 adult human cadaver head were randomly selected. All the cadaver underwent radiographic imaging with the cone beam CT. Based on the radiographic measurements, genial tubercle height, genial tubercle width, mandibualr height, distance from inferior border of mandible to genial tubercle and lastly mandibualr thickness were recorded. Results: A total of 20 cadavers were obtained from the department of anatomy. We observed that there were difference in the measurements obtained from CBCT to that of calliper but however when the statistics were applied this difference was not found to be significant. Discussion & Conclusion: No significant difference was seen between the two study group measurements cadaver dissections versus CBCT measurements. This radiographic technique may prove useful in preoperative planning for the mandibular osteotomy in genioglossus advancement procedures. In addition, this technique may allow for preparation of a pre-operative template to guide the surgeon. Future research will focus on the development of a simple surgical template to locate the genial tubercle accurately.
