Abstract

Using a descriptive case-by-case approach to evaluation of the results of ossicular chain reconstruction and cartilage tympanoplasty. Results: Most patients are at the age of 40.06 ± 11.06. Females account for a larger proportion. Symptoms are often tinnitus, hearing loss. Otoscopy results show 50% of patients having total adhesive otitis media, 50% others having focal adhesive otitis media. Preoperative hearing threshold is 15.78 ± 12.50 dB, average PTA before surgery is 43.36±17.45 dB, preoperative ABG is 27.65±13.71 dB . Computed tomography shows 10/16 patients, accounting for 62.5% have continuous ossicular chain, and 6/16 patients accounting for 37.5% have broken chain. Injury to the ossicles in adhesive otitis media: 100% of patients have damaged anvils, 31.25% others have damaged hammer and anvil, no cases have all 3 bones damaged. Cartilage tympanoplasty are applied in 81.25% of patients, 18.75% are treated with cartilage and temporomandibular fascia. The mean follow-up time is 9.6 ± 7.2 months. After surgery, tinnitus and hearing loss are relieved in 75% of patients. The mean airway threshold after surgery is 33.59 ± 14.90 dB, and ABG after surgery is 23.98 ± 14.3 dB.
