Three-Dimensional (3D) Printing in the Case of a Concurrent Polyp and an Ectopic Tooth

Nesha Rajendram et al. Cureus. .

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.

Keywords: ectopic tooth; paranasal sinus diseases; polyps; transanal endoscopy; ‎3d printing.
