Temporomandibular Joint Ankylosis with incidental findings of Odontogenic keratocyst and Mucous Retention Cyst: Report of a Case

Abstract

Temporomandibular joint ankylosis is inability to open mouth due to either a fibrous or bony union between the head of the condyle and the glenoid fossa. It is most commonly associated with trauma, local or systemic infection, tumors or systemic disease such as ankylosing spondylitis, rheumatoid arthritis, or psoriasis. Odontogenic keratocyst as defined by World Health Organization are known for their peculiar behavior, varied origin, debated development, unique tendency to recur, and disputed treatment modalities. The prevalence of mucosal retention cysts in the maxillary sinus varies considerably from report to report, perhaps as a function of population, geography and season. The detection and correct interpretation of the retention cyst is important for preventing unnecessary diagnostic procedures or surgical intervention. We report a case of temporomandibular joint ankylosis with incidental finding of odontogenic keratocyst and mucous retention cyst.
