鼓室硬化手术治疗进展

鼓室硬化系中耳慢性炎症后遗的黏膜或黏骨膜退行性病变,是引起传导性聋的一种常见原因。早期对鼓室硬化是否采用手术治疗存在争议,但近年来随着鼓室成形术的广泛开展,特别是人工听骨赝复物中部分听骨赝复物(partial os-sicular replacement prosthesis,PORP)和全部听骨赝复物(t

鼓室硬化症鼓室成型术25例临床分析

目的：总结手术治疗鼓室硬化症的临床经验。方法：回顾性总结2001年11月至2005年2月我科经治的25例鼓室硬化症临床资料。手术均在全麻显微镜下采用剥除硬化灶,修补鼓膜或加听骨链重建行Ⅰ期鼓室成型术。采用颞肌筋膜修补鼓膜,以自体乳突骨皮质或陶瓷人工听骨重建听骨链。结果：病灶侵及鼓膜、鼓岬、砧锤骨、镫骨及周围,均呈板障型乳突,无并发胆脂瘤。听力提高15?dB以上24例（96%）,术后4例有眩晕。结论：尽量清除硬化灶,形成宽大的鼓室,并重建鼓膜和听骨链,手术疗效与病灶影响听骨链程度有关,精确、熟练的耳显微外科技术是成功的关键。     

鼓室硬化研究现状

鼓室硬化（tympanosclerosis）是中耳在长期慢性炎症愈合后所遗留的中耳结缔组织退行性改变，是引起传导性聋的重要原因之一。本病由von Trohsch于1869年首先描述。过去常称为鼓室硬化症，按全国自然科学名词审定委员会公布的医学名词统称为鼓室硬化。随着鼓室成形术、蹬骨手术的广泛开展和手术显微镜的普遍应用，本病逐渐受到重视。我们就本病的病因、病理和发病机制、临床表现和诊断、预防和治疗作一综述。     

鼓室硬化症的术后听力判定及分析

Surgical treatment of tympanosclerosis

Tympanosclerosis as a cause of conductive hearing loss may require corrective surgery in carefully selected cases, although results of treatment have been controversial and must be viewed with caution. Currently available surgical techniques are reviewed and outcomes discussed.     

鼓室硬化类型与手术疗效(附40例临床分析)

目的 探讨硬化灶累及中耳部位与术前听力损失类型的关系、不同手术方式治疗鼓室硬化症的效果。方法 回顾性分析40例鼓室硬化患者术前资料,术中病灶记录,评估术后听力改善水平。结果 传导性耳聋的病例中最常见病灶侵及上鼓室、锤砧关节周围,而混合性耳聋的病例中病灶累及鼓岬的概率明显高于传导性耳聋的病例。术后气骨导间距小于20dB 18耳,成功率40%,Ⅰ型鼓室硬化症术后听力改善最显著(P＜0.05)。结论 听力损失的性质与硬化灶的范围及累及中耳的部位直接相关。手术处理是治疗鼓室硬化症的主要手段,手术方式则根据病变累及的范围和程度决定。     

鼓室硬化的手术疗效观察

目的:观察鼓室硬化手术采用综合技术的疗效。方法:回顾性分析151例(167耳)鼓室硬化(不含单纯鼓膜钙化)患者的临床资料。167耳均清除病灶并按需采用综合技术:①探孔开放上鼓室、乳突腔等;②自体骨片盾板修复,或碎骨填塞乳突腔;③听骨处理分为保持听骨链完整和听骨链重建;④可吸收膜片(透明质酸或聚二氧杂环乙酮)防再粘连;⑤鼓索神经弹压听骨;⑥铒-YAG激光或小凿清除面神经管骨质增生。术后1个月内测听力,出院3个月后复查1次,以后6个月~1年随访1次,以最后1次为随访结果(取0.5、1.0、2.0 kHz HL语频均数)。结果:167耳术前、术后气骨导差(ABG)分别为(39.74±12.54)dB和(20.68±11.80)dB,P<0.01。成功71耳(42.5%),有效48耳(28.7%),总有效率为71.3%(119耳)。167耳随访3~60个月,平均(11.01±10.24)个月,随访的ABG为(20.67±13.52)dB,与术前比较,P<0.01;与术后比较,P>0.05。随访12个月以上者96耳,ABG为(21.94±11.16)dB,与167耳随访结果比较,P>0.05。结论:应用综合技术能促进术后听力改善,并维持远期疗效。三骨全固定仍是治疗难点,对镫骨切除术应慎重对待。     

Analysis of long-term hearing after tympanosclerosis with total/partial stapedectomy and prosthesis used

Conclusion. Long-term hearing gain results are good after prosthetic reconstruction of the stapes in the tympanosclerotic ear. The type of stapedectomy, whether partial or total, does not affect the result of the surgery very much. Objectives. Comparative evaluation of the hearing results of total/partial stapedectomy technique and the prosthesis used within a 10-year follow-up period after stapedectomy in cases with dense tympanosclerosis and completely fixed stapes. Patients and methods. Twenty-five cases with completely fixed stapes due to generalized tympanosclerosis were included in this retrospective study between 1995 and 2005. Two-stage canal wall up procedure was planned for all cases, and stapedectomy was performed at the second stage. After the second stage, 25 ears in the sixth month, 18 ears in the first year, 14 ears in the second year, and 7 ears in the tenth year were available for follow-up. Preoperative and postoperative air–bone gap values of the patients and their hearing gain were compared. Total stapedectomy was carried out in 17 of the patients and partial stapedectomy in 8 of them. For ossiculoplasty, a plastipore total ossicular replacement prosthesis was used in 17 patients, homograft ossicle in 2 patients, and Teflon piston in 6 patients. Results. In 17 cases in which we used total stapedectomy, the average preoperative air–bone gap value improved from 40.23 to 18.47 in the sixth month, and from 38.4 dB to 9.6 dB in the tenth year. In eight cases in which we used partial stapedectomy, the average preoperative air–bone gap improved from 38.63 dB to 24.38 dB and from 35 dB to 17 dB, respectively. The average postoperative hearing gain with total stapedectomy was 21.76 dB in the sixth month and 28.8 dB in the tenth year. Hearing gain with partial stapedectomy was successively 14.25 dB and 18 dB. When we compared the results of total prosthesis and Teflon pistons among the materials used in ossiculoplasty, although hearing gain with total prostheses was better, the results were not statistically significant.     

Surgery for congenital anomalies of the middle ear with mobile stapes

Summary In a series of 104 patients with congenital middle ear anomalies operated on from 1964 to 1986, 27 cases were found in which the stapes footplate was mobile and the conductive deafness was due to an anomaly in the remaining part of the ossicular chain. In 8 cases the middle ear anomaly was caused by discontinuity of the ossicular chain owing to congenital malformation. In the other 19 ears, epitympanic fixation of the ossicular chain was observed, whether or not in combination with malformation of the stapes, incus or malleus. Ossicular chain reconstruction produced an improvement of at least 15 dB in 6 of the first 8 cases with discontinuity of the ossicular chain. The mean gain was 31 dB. Epitympanotomy with exposure of the fixed ossicle and if necessary ossicular chain reconstruction led to an improvement of at least 15 dB in 12 of the 19 ears, with a mean gain of 28 dB.

Surgical treatment of tympanosclerosis

During the 5-year period (1971-1976), 45 patients at the Shea Clinic underwent reconstructive surgery for tympanosclerosis. The most common ossicular chain problem was found to be malleus and incus fixation (33%); malleus, incus, and stapes fixation (22%); and stapes fixation (13%). The most successful reconstructive approaches included removal of tympanosclerosis from tympanic membrane or isolated plaque from ossicular chain, the use of the Partial Ossicular Replacement Prosthesis (PORP), and the Total Ossicular Replacement Prosthesis (TORP).     

Surgical treatment of tympanosclerosis

OBJECTIVE: To report the hearing results of the surgical treatment of tympanosclerosis. STUDY DESIGN: A retrospective review of surgically treated cases of tympanosclerosis. SETTING: A tertiary referral center. PATIENTS: One hundred fifteen patients with middle ear tympanosclerosis operated on between 1987 and 1996, with an average age of 36 years (range 18-59 years). Cases were classified into four groups according to Wielinga and Kerr. Those with an associated cholesteatoma were excluded. INTERVENTION: Depending on the ossicular status, either mobilization of the major ossicles or epitympanic bypass procedure, mobilization of the stapes or stapedectomy. MAIN OUTCOME MEASURES: The postoperative pure-tone average was compared with the preoperative levels by use of conventional audiometry. The air-bone gap was measured. RESULTS: The average postoperative air-bone gap was 18.0+/-10.21 dB in the type II group (attic fixation of the malleus-incus complex with a mobile stapes). 21.8+/-9.5 dB in the type III group (mobile malleus-incus complex, if present, with stapes footplate fixation), and 22.92+/-10.03 dB in the type IV group (fixation of both the stapes footplate and the malleus-incus complex). Patients with a fixed malleus and mobile stapes had significantly better hearing results than those with stapes fixation (p = 0.042, Mann-Whitney U test). CONCLUSION: In ossicular attic fixation, atticotomy and mobilization of ossicles yielded better results than did the epitympanic bypass procedure. The difference, however, did not reach statistical significance. Patients with fixed stapes treated with stapedectomy displayed good hearing results immediately after surgery, but the air-bone gap deteriorated after some time.
