Endoscopy Assisted Retrieval Of Accidental Oro-Antral/ Oro-Nasal Displacement Of Roots – A Report Of 2 Cases And Review Of Literature.

Background: Due to the proximity of palatal and buccal roots of upper premolars and molars to the maxillary sinus, apical displacement of root fragments to the antrum is common in dental practice. This article explains the possible anatomical variations and immediate management of retrieval of roots displaced into the antrum/ nasal cavity by the novel endoscopic approach rather than conventional removal. Clinical parameters like the size of the defect, position of the foreign body, and access to the anatomical location are imperative to be noted before choosing an approach for retrieval. Endoscopes had wide applications in the maxillofacial field, by utilizing that one can provide, minimally invasive and negligible surgical morbidity to the patient. A literature review is included to explain various retrieval techniques and the advantages and pitfalls of each procedure.
