Abstract
Objectives:
Study auditory tube dysfunction that occurs after jaw surgery.
Methods:
Two hundred sixty-eight patients were enrolled (60 males and 208 females; mean age, 24.3 years old) who were diagnosed with jaw anamorphosis symptoms and underwent orthognathic surgery of the lower jaw, and who were tested for auditory tube function before and after surgery at our hospitals between December 2000 and February 2012. Auditory tube function test pre- and post-operation were conducted, and post-operatively we searched for auditory tube dysfunction. Auditory tube dysfunction in a high rate was seen after lower jaw orthognathic surgery.
Results:
Post-operative auditory tube dysfunction was noted subjectively in 49 patients (18.3%) and determined by TM in 162 (60.4%). There is also a relationship between pre-operative SON and TTAG and post-operative TM aggravation.
Conclusions:
Post-operative auditory tube dysfunction correlated with pre-operative TTAG values, indicating that TTAG was a useful test for the prediction of TM aggravation. There was no correlation between post-operative auditory tube dysfunction and SON values.
