초록

Background and Objectives:This study is designed to examine the efficacy of mastoid obliteration (MO) in pa- tients who received canal wall up mastoidectomy (CWUM) for chronic otitis media (COM). Postoperative tym- panic membrane examination and hearing gain were taken into account. Materials and Methods:69 patients who underwent CWUM and tympanoplasty were included in this study. 44 patients underwent CWUM, tympa- noplasty, and MO (MO group) and 25 patients underwent CWUM and tympanoplasty (CWUM group), These two groups were compared with the postoperative finding of tympanic membrane such as perforation and retrac- tion of tympanic membrane, and recurrence of otorrhea. Preoperative and postoperative air conduction pure tone audiometry were used to compare the postoperative hearing gain of the two groups. To lessen the effect of other factors, 41 patients who underwent CWUM and tympanoplasty type 1 were included in comparing postoperative hearing gain. Results:There was no difference in postoperative finding of tympanic membrane or hearing gain whether MO was performed or not after CWUM and tympanoplasty in COM patients. Conclusions:In COM patients, introducing MO after CWUM and tympanoplasty showed no efficacy in preventing postoperative per- foration and retraction of tympanic membrane and recurrence of otorrhea or yielding better result in postopera- tive hearing gain. However, this study has several demerits such as small number of enrolled patients, short fol- low up period, and to being unable to exclude other factors that might have affected the results. Therefore, I presume collecting larger number of patients and considering more factors might lead to different result and plan to design a study with a significant result.
