Airway impairment in patients with TMJ ankylosis - A comparative study

The objective of this study was to compare the airway impairment in tmj ankylosis patients when compared to normal group of patients. for this study,two groups were devised as group 1 (norm,without tmj ankylosis) and group 2 (abnorm,tmj ankylosis). all variables relating airway were recorded on specially designed performa with consent. independent t sample test was applied to derive results in mean and standard deviation. total of 50 patients (25 normal,25 abnormal) when compared showed that lower and upper pharyngeal widths were severely affected in tmj ankylosis patients. anteropostrior angular measurements were showing reduced mandibulars growth. linear measurements of mandible were reduced due to ankylosis of tmj. neck line measurements implicated short neck and posterior positioning of mandible.
