Clinical Analysis Of 82 Cases Of Middle Ear Cholesteatoma

Objective: To investigate the clinical characteristics,diagnosis and treatment of cholesteatoma.Method: The relevant clinical data of 82 patients with cholesteatoma were analyzed retrospectively from June 2014 to March 2016 in our hospital.Including: gender, age, the main symptoms and signs, surgical treatment, observation of lesion, ossicular chain, postoperative status etc. select the air conduction(air conduction, AC) and bone conduction(BoneConduction BC), 0.5KHz,1kHz, 2KHz three frequency and obtain mean value, and statistically analys preoperative and postoperative data. Result: In all 82 cases, Han 40 cases(48.78%), Uygur 26 cases(31.70%), Kazakhs 7 cases(8.53%), Mongolian 5 cases(6.1%), Hui nationality 4 cases(4.87%), 39 cases of male, accounting for 47.56%, female 43 cases, accounted for 52.44%, age rangefrom7 to 73, mean age:35.89;damage of the malleus in 17 cases and incus destruction 29 cases, destruction of the stapes in 11 cases, ossicular absence of 22 cases,3 patients had no damage;The horizontal sections of the facial nerve canal damage in17 cases,6 cases damage to the vertical position,both of the two destruction in 11 cases.21 cases followed up,7 cases with canal wall up mastoidectomy,preoperative air conduction 52.10±6.19, postoperative 45.07±5.36, improve7.03±3.09.preoperative bone conduction 19.67±3.41, postoperative15.46±3.67, improve 4.2±1.89. 14 patients canal wall down, preoperative air conduction 54.89± 6.59 and postoperative 48.29±7.46, improve6.60±2.66.Preoperative bone conduction 21.42±5.46 and postoperative18.65±5.33, improve2.7±2.03. Conclusion: middle ear cholesteatoma is a common disease, suppurate, hearing loss as the main clinical manifestations, needs early diagnosis and treatmen to prevent complications, surgery should be according to the extent of the lesion, and residual hearing situation to be selected, prevention of recurrence.
