Do Something or Do Nothing? Anatomical Variants and Incidental Findings on Cone Beam CT. Part 2: Beyond the Dento-alveolar Complex and Neighbouring Structures

Abstract

Cone beam computed tomography (CBCT) is a popular and often indispensable imaging modality used for the dento-alveolar tissues and immediate surrounding structures. It can be used across several dental disciplines including endodontics, implant planning, oral surgery and orthodontics. Furthermore, it is commonly used in the medical specialties of oral and maxillofacial surgery (OMFS) and ear, nose and throat (ENT) surgery. In part 1 of this series, we described some of the common incidental findings found in the dento-alveolar complex and immediate neighbouring structures. Part 2 looks further afield and depicts some common and important incidental findings and anatomical variants that can be found on larger fields of view. CPD/Clinical Relevance: Many incidental findings are innocuous, yet their recognition and documentation are essential because some will warrant medical or surgical intervention.
