A case report. Ectopic molars that cause osteomeatal complex obstruction.

During a routine dental examination, a general dentist noticed facial asymmetry in a 42-year-old man. Dental radiography suggested a pathological condition in the sinuses. The dentist referred the patient to a head and neck surgeon for further examination. Computed tomography demonstrated ectopic molars in the maxillary sinuses blocking drainage of the sinuses.
