Objective:To compare the preoperative presentation, intraoperative findings, and postoperative outcomes between middle ear cholesteatoma with tympanosclerosis （MECwTS） and middle ear cholesteatoma without tympanosclerosis （MECw/oTS）, thereby investigating the clinical characteristics of MECwTS. Methods:A retrospective analysis was conducted on the clinical data of 120 patients with middle ear cholesteatoma. Patients were divided into two groups based on the presence or absence of concomitant tympanosclerosis: the MECwTS group （n=49） and the MECw/oTS group （n=71）. All patients underwent preoperative evaluations including temporal bone CT, otoscopic examination, pure-tone audiometry, tympanometry, and assessment using the Zurich Chronic Middle Ear Inventory （ZCMEI-21） quality of life scale. All patients underwent canal wall down mastoidectomy with tympanoplasty. Concurrent ossicular chain reconstruction was performed: partial ossicular replacement prosthesis （PORP） in 83 cases and total ossicular replacement prosthesis （TORP） in 37 cases. Intraoperative disease severity was assessed using the Cholesteatoma Comprehensive Score Scale （CCSS）. Postoperative follow-up lasted at least one year and included pure-tone audiometry, otoscopic examination, and the ZCMEI-21 scale administered at ≥1 year post-surgery. Preoperative and postoperative air-bone gap （ABG） and ZCMEI-21 scores were compared between the MECwTS and MECw/oTS groups. Additionally, surgical efficacy was defined as a postoperative ABG ≤20 dB; the hearing improvement efficacy of PORP versus TORP was compared based on this criterion. Results: ①Preoperative ABG showed no significant difference between the MECw/oTS and MECwTS groups（P>0.05）. Postoperative ABG was （18.65±10.21） dB in the MECw/oTS group versus （22.55±9.53） dB in the MECwTS group, demonstrating a statistically significant intergroup difference （P<0.05）. ②Intraoperative CCSS scores were significantly higher in the MECwTS group （8.04±2.18） compared to the MECw/oTS group （5.93±1.44） （P<0.05）. ③Preoperative ZCMEI-21 scores showed no significant difference between groups （P>0.05）. Postoperative ZCMEI-21 scores were （22.24±8.11） in the MECw/oTS group versus （27.02±7.21） in the MECwTS group, indicating a statistically significant difference （P<0.05）. ④Postoperative ABG ≤20 dB was achieved in 54 patients （65.06%, 54/83） in the PORP group and 16 patients （43.24%, 16/37） in the TORP group. This difference in efficacy rates was statistically significant （P<0.05）. The overall efficacy rate for ossiculoplasty was 58.33% （70/120）. Conclusion: Patients with MECwTS exhibit more severe middle ear and mastoid pathology compared to those with MECw/oTS, resulting in poorer postoperative hearing levels and quality of life outcomes. Both PORP and TORP implantation can improve postoperative hearing to some extent; however, PORP appears to offer superior hearing improvement efficacy compared to TORP.

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 evaluate the efficiency of autologous conchal cartlage in ossicular chain reconstruction in patients with chronic suppurative otitis media. METHOD: Seventy-three cases of chronic suppurative otitis media (COM) with or without cholesteatoma who had undergone mastoidectomy with tympanoplasty and ossicular chain reconstruction(OCR) using autologous conchal cartilage as prosthesis were studied retrospectively. Sixty-six cases of COM who had undergone mastoidectomy with tympanoplasty and without OCR were studied as control. The examination of pure tone hearing level of air conduction(AC) and bone conduction(BC) was done before operation, 2 months and 6 months after operation respectively. The pure tone average (PTA) of 0.5, 1.0, 2.0 kHz was observed. RESULT: The average air conduction gain was more than 15dB or the PTA (AC) was less than 25 dB 2 months after operation in 35 out of 73 cases who had undergone OCR. Nevertheless, the data became 56 out of 73 cases 6 months after operation. In the control group, The average air conduction gain was more than 15dB or the PTA(AC) was less than 25 dB 2 months after operation in 10 out of 66 cases who had not undergone OCR. The data became 14 out of 66 cases 6 months after operation. In OCR group, air bone gap(ABG) was less than 20 dB in 39 cases 2 months after operation and in 57 cases 6 months after operation. In the control group without OCR, ABG was less than 20 dB only in 11 cases 2 months after operation and in 16 cases 6 months after operation. By statistically analysis, there was significant difference of postoperative hearing improvement between the two groups. CONCLUSION The autologous conchal cartilage can be used as the material of prosthesis for ossicular chain reconstruction in the operation of chronic otitis media. It has many advantages, such as easily--obtained, good histocompatibility, easy to shape and so on.

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.

OBJECTIVE: To investigate the diagnose therapy and the postoperative curative effect of traumatic ossicular chain disruption and dislocation. METHOD: Eight cases (8 ears) with traumatic ossicular chain disruption. Six cases of unilateral conductivity deafness, 2 of mixed deafness still with conductive primarily. Eight ears all were performed tympanic exploration and ossicular replacement prosthesis, 1 ear with TORP (total ossicular replacement prosthesis). 4 ears with PORP (partial ossicular replacement prosthesis), 2 with ossicular chain reset, 1 with artificial incus reconstruction. The treatment effect was compared by the preoperative and postoperative ABG (air bone gap). RESULT: Preoperative average ABG was 42. 9 dB, the average ABG 3 weeks after operation was 22.3 dB, which reduced 20.6 dB compared to the preoperative, having a statistically significant difference (t = 22.10, P < 0.01). The average ABG was 18.6 dB 6-8 months after operation, which reduced 24.3 dB compared to the preoperative, having a statistically significant difference (t = 12.813, P < 0.01). CONCLUSION The conductivity hearing loss after traumatic ossicular chain disruption or dislocation is preferred operation treatment, and replacement should use different ways according to the operation in case, and the hearing improvement was obvious.

BACKGROUND AND OBJECTIVES: Tympanosclerosis is a nonspecific and irreversible result of chronic inflammation or infection of the middle ear. However, there remains disagreement about how best to surgically treat tympanosclerotic ossicular fixation, with the controversy over its management when stapes is involved. The aim of this study was to evaluate operative findings and hearing results of tympanosclerosis involving the ossicular chain, which in turn would establish better surgical treatment of tympanosclerotic ossicular fixation. SUBJECTS AND METHODS: In this prospective study conducted from Mar 2000 to Dec 2007, 38 patients with tympanosclerosis who had undergone surgical treatment were evaluated. The clinical and operational records and pre- and postoperative pure tone audiograms were reviewed. RESULTS: Operative findings showed stapes fixation is the most common. In 8 patients (21.1%), stapes was mobile, while, in the remaining 30 patients (78.9%), stapes fixation was found. In all cases with stapes fixation, stapes mobilization was possible. Following hearing result reporting guideline by the Korean Otological Society, the success rate of middle ear surgery was 68.4% (26 of 38 patients). In cases with stapes fixation, the success rate was 66.6% (20 of 30 patients), while, in cases with no stapes fixation, the success rate was 75.0% (6 of 8 patients). However, there was no statistical significance between the two groups. CONCLUSION: Stapes fixation was found in 78.9% of tympanosclerotic ossicular fixation. In management of tympanosclerotic stapes fixation, meticulous excision of tympanosclerotic plaques and removal of new bone formation around stapes footplate after adequate exposure could achieve a relatively good hearing result without stapes surgery.

OBJECTIVETo evaluate the effect of ossicular reconstruction with partial ossicular replacement prosthesis (PORP) in patients with tympanosclerosis.

METHODSThe data of 31 cases of tympanosclerosis treated between 1992 and 2009 were reviewed. Of the 31 patients, 17 (17 ears) underwent ossicular reconstruction with porous macromolecular polyethylene PORP, and 14 (14 ears) with bioceramic PORP. All the patients were followed up for 3-24 months.

RESULTSSignificant improvement was found in postoperative speech frequency (500, 1000, 2000 Hz) pure tone average (PTA) and air-bone gap (ABG) (P < 0.05) after the treatments without statistically significant differences between the two groups (P > 0.05).

CONCLUSIONPorous macromolecular polyethylene and bioceramic are valuable ossicular prosthesis for tympanosclerosis.
