Recurrent sinus of the cheek due to a retained foreign body: report of an unusual case.

Pathological sinuses in the maxillofacial region are frequently encountered in clinical practice. These sinuses may be a sequelae of periapical and periodontal pathologies or infections like osteomyelitis, actinomycosis etc. Classical clinical symptoms and radiographic features accompany all these infections. Rarely, sinuses in the oro-facial region can be sequelae of retained occult foreign bodies like wood in the soft tissues. We report a case of recurrent sinus of the cheek caused by an occult wooden splinter and discuss its diagnosis and clinical management.
