Abstract:
Objective:Retrospective analysis of clinical data of 123 patients with atticotomy, exploring the clinical characteristics of patients undergoing atticotomy and the efficacy of hearing reconstruction methods. Methods:123 patients with atticotomy were divided into three groups according to the ossicular chain treatment method: preservation of the ossicular chain group（37 cases）, cartilage elevation of stapes group（49 cases）, and PORP group（37 cases）. The clinical characteristics of patients with atticotomy, preoperative and postoperative hearing levels of the three groups of patients, and postoperative complications were analyzed. Results:①89.43%（110/123） of patients who underwent atticotomy were pars flaccida cholesteatomas, while 10.57%（13/123） of patients were secondary cholesteatoma, adhesive otitis media, pars tensa cholesteatomas, congenital cholesteatoma, and external auditory canal cholesteatoma; ②The group with preserved ossicular chain had a shorter medical history compared to the other two groups, and the difference was statistically significant（P<0.001）. The group with preserved ossicular chain had smaller inter group ABG values and average ABG values at frequencies of 500 Hz, 1 000 Hz, 2 000 Hz and 4 000 Hz before surgery compared to the other two groups, and the difference was statistically significant（P<0.001）; The differences in ABG frequencies and average ABG between the three groups of patients before and after surgery were statistically significant（P<0.05）; Postoperative ABG: The group preserving the ossicular chain had a smaller difference compared to the other two groups, with a statistically significant difference（P<0.05）. There was no statistically significant difference between the cartilage plus high stapes group and the PORP group（P>0.05）; ③At 3 months post surgery, all patients achieved ear dryness. Two patients experienced delayed facial paralysis after conservative treatment, and all recovered. One patient had a slight decrease in bone conductivity due to the influence of grinding during hammer anvil fixation surgery, and one patient experienced a recurrence after 4 years due to residual surgery. 81 patients（65.85%） experienced non cartilage repair area invagination during postoperative follow-up, of which 5 patients（4.07%, 5/123） underwent a second surgery. Although the rest of the patients had local invagination, they could still self clean and did not form a cholesteatoma. The total recurrence rate was 4.88%（6/123）, with an average recurrence time of 4 years. Conclusion:Atticotomy surgery is most commonly used for pars flaccida cholesteatomas with limited scope. The incidence of postoperative retraction is high, and regular follow-up is necessary; When conditions permit during surgery, priority can be given to preserving the ossicular chain for better postoperative hearing. Both cartilage elevation of stapes and PORP implantation can effectively improve hearing, and there is no difference in postoperative hearing between the two methods. However, there is a risk of detachment and high cost after PORP surgery, and cartilage elevation of stapes is limited by insufficient height and stapes head erosion. Therefore, it is necessary to choose a comprehensive hearing reconstruction method based on the patient's condition.
