This study proposes a novel intraoral approach combined with sub-sigmoid osteotomy to effectively and safely remove of ectopic third molar teeth without complications.
The procedure included a sub-sigmoid osteotomy to expose and remove the ectopic tooth, followed by fixation of the osteotomized coronoid with titanium plates. Preoperative cone beam computed tomography (CBCT) was used for precise tooth localization.
The ectopic third molar was successfully removed with minimal bone removal. One intraoperative complication, a bad split of the anterior ramus, was observed but managed effectively. Postoperative healing was uneventful, with no nerve injury, infection, or reduced mouth opening.
The transoral sub-sigmoid osteotomy technique is a reproducible, effective method for ectopic third molar removal, avoiding extraoral scars, nerve damage, and extensive dissection. Preoperative planning using CBCT is essential to prevent complications, making this technique a valuable alternative to traditional approaches.
本研究提出一种结合乙状窦下截骨术的新型口腔内入路，以有效且安全地拔除异位第三磨牙且无并发症。
该手术包括乙状窦下截骨术以暴露并拔除异位牙，随后用钛板固定截骨后的冠突。术前使用锥形束计算机断层扫描（CBCT）进行精确的牙齿定位。
以最小的骨去除量成功拔除了异位第三磨牙。术中观察到1例并发症，即下颌支前部严重裂开，但得到了有效处理。术后愈合顺利，无神经损伤、感染或张口受限。
经口乙状窦下截骨术是一种可重复的、有效的拔除异位第三磨牙的方法，可避免口腔外瘢痕、神经损伤和广泛的解剖。使用CBCT进行术前规划对于预防并发症至关重要，使该技术成为传统方法的有价值替代方案。
