Pre-operative survey
The patient was diagnosed as granular myringitis by otoscope showed eardrum granulation. Patient’s geography data, disease side, involved location were recorded by local finding. The past-history, previous otologic procedure, presenting symptoms, and bacterial culture results were also recorded and analyzed.
Pure tone audiogram (PTA) and tympanogram (Tym) are not routine assessment but a useful tool to help us to access the middle ear status. If patient with more advanced clinical symptoms also received preoperative HRCT scan to exclude other middle ear diseases.
