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.

OBJECTIVE: To assess hearing effect of ossicular chain reconstruction with titanium ossicular replacement prosthesis during mastoidectomy with synchronous ossiculoplasty in chronic middle ear disease. METHOD: Retrospective reviews were performed for 139 patients who had underwent mastoidectomy and tympanoplasty with titanium ossicular replacement prostheses at the same time between 2008 and 2011. The partial ossicular replacement prostheses (PORP) were used in 91 patients and the total ossicular replacement prostheses (TORP) were used in 48 patients respectively. All patients had follow-up for 2 to 5 years. The preoperative and postoperative mean air conduction and air-bone gaps(ABG) for the four frequencies (0.5, 1.0, 2.0 and 4.0 kHz) were evaluated. The improvement of mean air conduction and ABG over the same frequencies were measured. A postoperative ABG less than or equal to 20 dB was considered a successful operation. The hearing results of titanium PORP and TORP were compared. RESULT: The mean air conductions were (53.97 +/- 11.32)dB and (36.80 +/- 11.68) dB preoperatively and postoperatively in PORP group. The mean improvement in air conduction was (17.17 +/- 5.79)dB. The mean ABG was (31.84 +/- 6.17)dB and (15.13 +/- 7.22)dB preoperatively and postoperatively in PORP group. The mean improvement in ABG was (17.71 +/- 5.5)dB. The difference of hearing threshold between preoperative and postoperative had statistical significance (P < 0.01). The mean air conduction were (58.05 +/- 11.35)dB and (44.53 +/- 13.15)dB preoperatively and postoperatively in TORP group. The mean improvement in air conduction was (13.52 +/- 7.81)dB. The mean ABG; were (35.67 +/- 5.73)dB and (21.48 +/- 7.01)dB preoperatively and postoperatively for TORP group. The mean improvement of hearing threshold in ABG was (14.18 +/- 7.53)dB. The difference of hearing threshold between preoperative and postoperative had statistical significance (P < 0.01). ABG less than 20 dB after operationwas happened in 68.63% of the patients (74.73% for PORP and 54.17% for TORP). There was statistically significant difference between PORP and TORP (P < 0.05). CONCLUSION We conclude that titanium ossicular reconstruction during mastoidectomy with synchronous ossiculoplasty give stable and excellent hearing results. We obtained better results with PORP than with TORP.

OBJECTIVE: To study the effects of different types of prosthesis used in ossiculoplasty on mastoidectomy of treating chronic otitis media. METHOD: One hundred and forty three patients with chronic otitis media were treated by canal wall-down tympanoplasty with ossiculoplasty in a single stage. According to material of prosthesis, they were classified as titanium group (group A, 52 cases), hydroxypatite group (group B, 47 cases) and autogenous bone group(group C, 44 cases). The postoperative complication and hearing thresholds were analyzed in the 24 months follow-up. Average postoperative air-conduction gain and air-bone gap were measured at four frequencies: 0.5, 1.0.2, and 4.0 kHz. RESULT: 12-month after operation, the average air threshold and air-bone gaps of the three groups were reduced (P < 0.05). The reconstruction successful rate (78.7%) of group A was slightly better than that of B, C (68.1%, 70.4%), there was no statistically significant difference. The difference of the average air threshold and air-bone gaps of group B, C after 24-month of operation and 12-month after operation was statistically significant (P < 0.05). The reconstruction successful rate (48.9%, 45.5%) of group B, C was lower than that of A (76.9%), the difference was also statistically significant (P < 0.05). CONCLUSION Prostheses using titanium type could give good functional results and strong stability with low complication.

OBJECTIVE: To investigate the effect of different malleus treatments on the postoperative efficacy in the tympanosclerosis patients receiving ossicular chain reconstruction. METHOD: Fifty-nine patients (62 ears) with tympanosclerosis were treated by ossicular chain reconstruction. All the patients were divided into three groups, including malleus removal group (A, 24 ears), retaining only the malleus handle group (B, 18 ears) and the intact malleus group (C, 20 ears). All the patients were followed up 3 months pre-operation, 3 months and 1 year post-operation by audiometric measurement (the average hearing threshold at 0.5, 1.0, 2.0 kHz HI). Tympanic membrane was examined by ear endoscope. RESULT: The pre-operation mean air bone gap (ABG) in these groups were 40.07 +/- 77.56 dB, 37.31 +/- 76.45 dB, and 36.75 +/- 76.72 dB, among which the difference had no statistical significance (P > 0.05). At 3 months after operation, the ABG in all cases was improved at 0.5, 1 and 2 kHz. The difference of ABG improvement among these three groups had no statistical significance (P > 0.05). One year after surgery, the ABG of the three groups were decreased by 17.92 +/- 9.28 dB, 16.76 +/- 5.19 dB and 10.58 +/- 7.38 dB respectively. The hearing improvement in group C is less than the other two groups (P = 0.03, P = 0.016). The difference of hearing improvement between group A and group B had no statistical significance(P > 0.05). Group A and group B each have one case of tympanic membrane perforation and artificial ossicle falling off. CONCLUSION The operating processes of malleus in ossicular chain reconstruction of patients with tympanosclerosis were introduced. In terms of short-term efficacy, the three groups showed no significant difference. However, the long-term efficacy of the patients in the group A and group B were better compared with the group C.
