Objective: This study aims to assess the effectiveness of endoscopic tympanoplasty without mastoidectomy in the management of active mucosal chronic otitis media (COM) patients with mastoid and tympanic antrum lesions.
Methods: It is a prospective controlled study where 42 patients with active mucosal COM with mastoid and tympanic antrum lesions or normal aeration were recruited from the outpatient clinic of the otology department, Eye Ear Nose and Throat Hospital of Fudan University. All patients underwent endoscopic tympanoplasty without mastoidectomy by using the underlay technique with tragal cartilage graft with one side-perichondrium. The follow-up period was at least 3 months and results were evaluated in terms of graft uptake, ear dryness and hearing improvement.
Results: Statistics showed no significant difference in graft uptake between the mastoid and tympanic antrum lesions group (90.5%) and the normal aeration group (95.2%). There was no significant difference in ear dryness between the mastoid and tympanic antrum lesions group (95.2%) and the normal aeration group (100%). Hearing improvement was comparable in the 2 groups.
Conclusion: Regardless of the occurrence of soft density shadows in temporal bone showed by high-resolution computerized tomography in the mastoid and tympanic antrum, mastoidectomy is an unnecessary procedure for dealing with active mucosal COM without cholesteatoma. Therefore, this study shows that endoscopic tympanoplasty without mastoidectomy may be applied to active mucosal COM without cholesteatoma.
