OBJECTIVE: We analyzed audiologic and surgical findings in @entity1 with @entity393 ( @entity393 ) with an intact tympanic membrane (TM) that was of a non-inflammatory origin. METHODS: We reviewed data from @entity1 who underwent exploratory tympanotomy for @entity393 with intact TM from January 1995 to November 2012. @entity1 with diseases of non-inflammatory origin were enrolled (69 @entity1 ; 79 ears). @entity1 were categorized into two groups: non- @entity130 (50 ears) and @entity130 (29 ears). Demographic data, intraoperative findings, and audiologic results were obtained and analyzed. RESULTS: Overall, the second decade was the most common age of diagnosis in both the non- @entity130 and @entity130 groups. Operative findings showed that @entity3029 was more prevalent than @entity2170 ; all @entity130 group subjects had @entity3029 . Short columellization or partial ossicular replacement was the most frequently adopted surgical procedures in both groups. Overall, audiologically, air-conduction thresholds (ACs) and air-bone gaps were significantly improved over the short- and long-term period in both groups. However, the non- @entity130 group had significantly higher preoperative ACs than the @entity130 group, especially at low frequencies. CONCLUSION: This study provides clinicians with useful information regarding the clinical characteristics of @entity393 with intact TM of non-inflammatory origin.
