Removal of the Residual Roots Displaced Into the Maxillary Sinus via Endoscopy.

Minimally invasive endoscopic surgery has been developed for various indications in the craniomaxillofacial area. The case report presented in this article is focused on the possibility of removing the residual roots displaced into the maxillary sinus by means of an endoscopic technique. When planning endoscopic surgery to access the residual roots displaced in the maxillary sinus, we performed 2 different approaches into the maxillary sinus, a transnasal approach through the middle or inferior turbinate and transoral approach via the anterior maxillary sinus wall. The endoscopic surgical approach described is reliable and minimally invasive for removing the residual roots displaced into the maxillary sinus. Therefore, we concluded that the application of this clinical procedure is worth promoting.
