TMJ Ankylosis is a debilitating disease with wide ranging functional and aesthetic manifestations. One of the primary concerns of the patient are the episodes of obstructive sleep apnea which are relived following arthroplasties in bilateral cases of TMJ Ankylosis due to increase in the nasopharyngeal airway. This phenomenon is also noted in unilateral cases but the possible mechanism and radiographic changes have not been found in literature. We present a case of a 7 year old female patient with TMJ ankylosis of the right side. Pre-operative photographs and a lateral cephalogram of the patient were taken. Saddle angle, depth angle, vertical angle, roof angle as well as the posterior height, total depth and length of the floor of the Nasopharynx were measured. The position of the hyoid bone was also measured by utilizing the values of H-Rgn, AA-H, C3-H and C3-Rgn. These measurements were compared with readings obtained on the post-operative lateral cephalogram and the differences were noted.
