Abstract:
The removal of an ectopic molar tooth at the pterygomaxillary junction may be challenging. This paper presents the use of three-dimensional (3D) printing of the paranasal sinus for careful planning in a way that reduces the risk and makes surgical procedures more effective. A 26-year-old gentleman presented to the ENT department with a left antrochoanal polyp and an incidental ectopic tooth at the pterygomaxillary junction. Pre-operative 3D reconstruction of the maxillary cavity and subsequent 3D printing were used to guide the surgery and counsel the patient on potential outcomes. Left anterior functional endoscopic sinus surgery was subsequently done, and the antrochoanal polyp was completely removed. The preoperative computed tomography scan allowed for the production of the printed model to the exact size and dimensions of the ectopic molar tooth to facilitate the planning of the surgery and to aid in consenting the patient for the treatment.
摘要:
去除翼状腋窝交界处的异位磨牙可能具有挑战性。本文介绍了鼻旁窦的三维(3D)打印的使用,以减少风险并使外科手术更有效的方式进行精心计划。一位26岁的绅士出现在耳鼻喉科,他的左前鼻孔息肉和翼状腋窝交界处的偶然异位牙齿。上颌骨腔的术前三维重建和随后的3D打印用于指导手术,并就潜在的结果向患者提供咨询。随后进行了左前功能性内窥镜鼻窦手术,后鼻窦息肉被完全切除。术前计算机断层扫描扫描允许将打印模型生产为异位磨牙的确切大小和尺寸,以促进手术计划并帮助患者同意治疗。
