Abstract
Objective: Some patients with jaw anamorphosis symptom who underwent plastic surgery for lower jaw complain of earache, feeling of obstruction, and hearing disorders.By conducting auditory tube function tests before and after plastic surgery for the lower jaw, we studied pathophysiology, incidence, causes and treatment of auditory tube dysfunction.
Method: This study was carried out between 2000 and 2010. The 290 patients were divided into 4 groups(A to D) and compared for the rate of aggravation of auditory tube function and duration for the function to recover.
Results: Approximately 30% of patients with TM aggravation complained of ear symptoms. Among subjective ear symptoms, the most prevalent was feeling of ear obstruction, followed, in the order, by discuses. The number of patients who complained of ear symptoms was 23.9% in group A, 17.1% in group B, 6.7% in group C, and 9.1% in group D. Aggravation of auditory tube function (was determined by TM in 62.7% in group A, 44 (53.7%) in group B, 14 (46.7%) in group C, and 12 (54.5%) in group D.
Conclusion: Postoperative auditory tube dysfunction recovered spontaneously in an average of 3.48 days without providing ventilation treatment while patients were placed under observation. Patients with postoperative auditory tube dysfunction that lasted longer than 4 days or with complaints of subjective symptoms were given ventilation treatment. All cases were cured within 14 days.
