BACKGROUND: The primary goal in chronic otitis media is the creation of a dry, safe ear with hearing preservation and reconstruction. This study was designed to evaluate the authors' experience using autologous bone pate and conchal cartilage for mastoid obliteration in canal wall down tympanomastoidectomy. METHODS: A retrospective long-term review in 2003 of thirty-nine ears was performed, which underwent mastoid obliteration in canal wall down tympanomastoidectomy between 1993 and 2002 performed by the senior author. Data included questionnaire results, clinical observation as well as pre- and postoperative audiometry. RESULTS: Long-term follow-up shows, that 38 out of 39 ears maintained a small, dry, healthy mastoid cavity. Recurrent cholesteatoma occurred in a single patient. A self-cleaning mastoid bowl was achieved in 90 %, resulting in reduced follow-up visits. Postoperative vertigo in canal wall down revision surgery is clearly diminished due to the mastoid obliteration. Overall, 92 % of patients are satisfied with the surgical result. CONCLUSION: Obliteration of a canal wall down mastoid cavity by autologous bone pate and conchal cartilage is a reliable and effective technique that results in a dry, trouble free mastoid cavity in 90 % of the patients with chronic otitis media. 相似文献

OBJECTIVES: This study was designed to evaluate the authors' experience with canal wall reconstruction (CWR) tympanomastoidectomy with mastoid obliteration in the treatment of chronic otitis media with cholesteatoma. STUDY DESIGN: Institutional review board approved retrospective case review. METHODS: Retrospective review was performed of all patients undergoing CWR tympanomastoidectomy with mastoid obliteration from 1997 to 2004. Data included pre- and postoperative audiometry, findings at second look surgery with ossiculoplasty, and postoperative complications including wound infection and canal wall displacement. RESULTS: One hundred thirty ears in 127 adults and children underwent the procedure. Mean time postoperative was 48 (range 2-94) months. A second look ossiculoplasty was performed in 102 (78%). Percentage of ears that remain safe without evidence of recurrence was 98.5. The postoperative infection rate decreased from an initial rate of 14.3% to 4.5% for the last 88 ears after protocol modification. Recurrence occurred in two (1.5%) patients, requiring conversion to a canal wall down mastoidectomy. CONCLUSIONS: A CWR technique can provide improved intraoperative exposure of the middle ear and mastoid without creating a mastoid bowl and reduces the incidence of recurrent disease. A single procedure is used for all patients with acquired cholesteatoma, including children. 相似文献

The operative findings of 66 patients who underwent revision mastoid surgery for recurrent chronic otitis media were analyzed for the causes of failure of the primary procedures. Recurrent cholesteatoma was found in 41% of the canal wall down and 70% of the canal wall up procedures requiring revision. Additional causes of failure included granulation tissue in unexenterated cells, particularly in the tegmental cells (41% of all cases and 64% of cases without cholesteatoma) and cells of the sinodural angle (38% of all cases and 58% of cases without cholesteatoma). The need for thorough exenteration of cells, particularly the tegmental cells and cells of the sinodural angle, mastoid tip, and facial recess, and the importance of lowering the facial ridge in canal wall down procedures were stressed. Following these principles, the success rate in creating a dry ear in 48 patients who had undergone from one to three previous mastoid procedures was 85% (mean follow-up three years). 相似文献

OBJECTIVE: To describe an effective technique for mastoid cavity obliteration in canal wall down tympanomastoidectomy for chronic otitis media and review its efficacy in producing a dry, low-maintenance, small mastoid cavity. DESIGN:: Retrospective clinical study of a consecutive series of procedures from 1995 to 2000. SETTING: Tertiary referral center and institutional academic practice in otology and neurotology. PATIENTS: Sixty consecutive procedures for active chronic otitis media with a minimum follow-up of 12 months (mean, 31 mo; range, 12-80 mo). INTERVENTION: All patients had canal wall down mastoidectomy with simultaneous tympanoplasty including split-thickness skin grafting. An inferiorly pedicled, periosteal-pericranial flap was used in conjunction with autologous bone pate to obliterate the mastoid cavity. The additional length provided by the pericranial extension of the flap permitted it to reach superior to the lateral canal and into the sinodural angle, with improved coverage of bone pate and better reduction of cavity size. OUTCOME MEASURES: The primary outcome measure was control of suppuration and creation of a dry, low-maintenance mastoid cavity, which was assessed using a previously developed semiquantitative scale. This scale includes a temporal dimension to assess control of infection. Secondary outcome measures included postoperative complications (i.e., hematoma, infection, flap necrosis, and meatal stenosis) and incidence of recurrent or residual cholesteatoma. RESULTS: Forty-nine ears (82%) maintained a small, dry, healthy mastoid cavity. Five ears (8%) had intermittent otorrhea easily controlled by topical treatment. Six ears (10%) had suboptimal control of otorrhea, of which four had meatal stenosis. There were no residual or recurrent cholesteatomas. Outcomes remained stable over progressively longer follow-up, up to 80 months. CONCLUSION: Obliteration of a canal wall down mastoid cavity by a postauricular periosteal-pericranial flap with autologous bone pate is a reliable and effective technique that results in a dry, trouble-free mastoid cavity in 90% of patients with active chronic otitis media. 相似文献

OBJECTIVE: To evaluate clinical and audiologic data as well as operative findings and postoperative follow-up in the management of chronic cholesteatomatous otitis media with canal wall down mastoidectomy (CWDM). STUDY DESIGN: A retrospective review of cases followed up between 1990 and 2002. SETTING: Tertiary referral centre. METHOD: Two hundred one patients with chronic otitis media with cholesteatoma underwent CWDM. MAIN OUTCOME MEASURES: Clinical presentation, surgical findings, and audiologic evaluation were assessed. RESULTS: Preoperatively, eight patients suffered from vertigo and four presented with facial nerve paralysis. In 40 patients (20%), erosion of the lateral semicircular canal was found, and in 31 patients (15%), there was dehiscence of the facial nerve canal. Dural plate erosion and sinus plate dehiscence were found in 13 and 17 patients, respectively. Nine patients experienced serious endocranial complications at their admission. The malleus was noted to be intact in the majority of patients in all age groups. The incus was eroded or absent in most of the cases in all age groups. On postoperative evaluation 3 months after surgery, 195 audiograms were performed, with a mean pure-tone average of 55 dB HL and a mean air-bone gap of 30 dB HL. CONCLUSION: Although CWDM has the disadvantages of the necessity to avoid water insertion in the external auditory canal and lifelong mastoid care, it is an effective treatment in a single-step procedure for patients with advanced disease and for those who refuse to submit to postoperative follow-up. 相似文献

ObjectivePatients with chronic otitis media with/without cholesteatoma present a significant challenge to safe cochlear implantation (CI). The aim of our study is to describe our experience and propose management options for CI in patients with chronic otitis media.Study designRetrospective case study.SettingTertiary academic center.Subject and methodsWe enrolled the 9 ears of 8 subjects who received CI in the ear with chronic otitis media from 2006 to 2013 by a single surgeon. CI was performed as a single-stage or staged operation with mastoid surgery according to the activity of ear infection.ResultsSix patients had bilateral chronic otitis media and 2 patients had long history of sensorineural hearing loss at contralateral ear. CI was performed with simultaneous radical mastoidectomy with closure of the EAC as a single-stage in 3 ears with a history of previous open cavity mastoidectomy and no active discharge. Staged CI was performed in 6 ears, after radical mastoidectomy with closure of the EAC in 3 ears and after intact canal wall mastoidectomy in 3 ears, due to active inflammation or complications related to otitis media. In one patient, wound infection had occurred, and implant was removed along with implantation at contralateral ear. Other subjects showed no evidence of recurrence.ConclusionDecision whether implantation as a single-stage or staged operation depends on the presence of active inflammation. Single-stage CI with proper mastoid surgery can be performed in patients without active inflammation. Staged procedure need to be done in ears with active inflammation. Proper application of mastoid surgery leads to safe CI for patients with chronic otitis media. 相似文献

Many advances have occurred in the treatment of acute suppurative inflammation of the middle ear; however, the problem of chronic otitis media with cholesteatoma still persists today. This paper deals with the author's experience over 5 years using the intact canal wall tympanoplasty with mastoidectomy treatment in chronic otitis media with particular emphasis on the treatment of cholesteatoma both in adults and children. From May 1, 1976 to May 1, 1981, 204 ears were operated on for chronic otitis media with the tympanoplasty with mastoidectomy technique. Of this group, 104 ears were operated on using the intact canal wall technique when there was cholesteatoma present. The major emphasis of this paper will be to evaluate those ears with cholesteatoma. The technique of the procedure used and modifications that have been made are outlined with particular reference as to why modifications were made as problems arose while observing this group of patients. The results of this study suggest that there is a greater incidence of recurrence of cholesteatoma using the intact canal wall technique in children than in adults. It is believed that this higher rate is due to ongoing eustachian tube difficulties present in children. It is also felt that the intact canal wall technique does provide a better chance of auditory functional rehabilitation than an open cavity ear procedure. The problem of residual cholesteatoma still exists using the intact canal wall procedure; however, the problem seems to be well taken care of using a planned two-stage procedure. This is particularly necessary because two-thirds of all residual cholesteatoma was found to be in the middle ear. The conclusions of the study suggest that a planned two-stage intact canal wall tympanoplasty with mastoidectomy can accomplish the goals of cholesteatoma surgery, i.e., control of the disease and improved functional results. It is felt that, if cholesteatoma recurs in a child, the revision operation should be converted to a properly performed open cavity procedure. It was felt that the anatomic removal of the posterior bony canal wall in an open cavity procedure does not render an ear safe from further problems. 相似文献

Tympanoplasty: review of 400 staged cases 总被引:8,自引:0,他引:8
Staging of tympanoplasty is important in the management of patients with chronic otitis media. It allows establishment of an air-containing middle ear space and adequate postoperative hearing levels in a large proportion of patients with severely diseased ears. The results of 400 staged procedures performed over a 3-year period at the House Ear Clinic, Los Angeles are reported. Staging was performed in 75% of tympanoplasty with mastoidectomy cases and in 15% of ears not requiring mastoid surgery. Closure of the air-bone gap to 20 dB or less occurred in 68% of patients with intact stapes. Mucous membrane problems were the most common reason for staging. Almost one third of cases with middle ear cholesteatoma at the first stage had residual disease on reexploration. Staging of tympanoplasty continues to be an important technique in management of severely diseased ears. 相似文献

OBJECTIVE: Burow's solution was developed by Karl August von Burow in the 19th century as an ear drop. Thorp et al. reported its excellent effect on chronic suppurative otitis media in 1998. We applied Burow's solution to intractable chronic purulent diseases of the external and middle ear in the 12 months from February 2001. SUBJECTS: Subjects were 25 ears of 21 patients--35-79 years old, 10 men's ears and 15 women's ears--whose disease has continued for an average of 3.78 years. Diseases and patients are as follows: 1) 11 ears with postoperative mastoid cavity problems, 2) 7 ears with chronic external otitis and chronic eczema of the external ear canal, 3) 7 ears with fungal otitis externa, 4) 6 ears with chronic otitis media with perforation, and 5) 2 ears of chronic granulated myringitis. METHOD: The solution was dropped into the ear canal once a day for 10 min or cotton balls soaked with the solution were applied to the canal wall. Criteria of efficacy were divided into cured, effective and unchanged. RESULTS: 8/11 ears with a cavity problem were cured (72.7%) and 3 ears showed treatment to be effective. All 7 ears with chronic external otitis and chronic eczema were cured. All 7 ears with fungal otitis externa were cured. 4/6 ears (66.6%) with chronic perforated otitis media were cured and 1 ear each showed treatment to be effective and 1 unchanged. Two chronic granurated myringitis were cured. Twenty of 25 ears (80%) were cured. Pre- and posttreatment audiometries showed almost the same. The cure appeared within 3 days to 3 weeks. The solution was not effective against mucoid secretion, cholesteatoma, or residual mastoid cells. The day after treatment, serous secretion appears temporarily. CONCLUSION: Burows's solution is seemed to be very effective and nonototoxic as an otic drop for treating suppurative ear diseases. 相似文献

Reconstruction of the radical mastoid. 总被引:2,自引:0,他引:2
Open cavity techniques (radical mastoidectomy, canal wall down tympanomastoidectomy, modified radical mastoidectomy) are well established surgical procedures for the treatment of chronic otitis media. Despite their effectiveness in exteriorizing cholesteatoma, they are associated with a 20 to 60 percent incidence of persistent intermittent drainage. In an effort to eliminate this problem, we have employed a Palva flap and medial graft technique to reconstruct the mastoid cavity and middle ear space in those patients with chronically draining ears. Between 1987 and 1990, 28 patients underwent this procedure. Twenty-six of these (93%) had complete obliteration of the mastoid cavity and successful tympanic membrane reconstruction. Two of 28 (7%) had a persistent tympanic membrane perforation and intermittent drainage following their surgery. Based on these results, this procedure is effective in eliminating intermittent drainage associated with the open cavity techniques. The indications for this procedure, the specifics of the surgical technique, and the postoperative results are discussed. 相似文献

Surgical treatment of chronic middle ear disease. III. Revisions after tympanomastoid surgery 总被引:1,自引:0,他引:1
T Palva 《Acta oto-laryngologica》1988,105(1-2):82-89
Revision surgery was performed in 185 ears which had earlier undergone a total of 276 tympanomastoid operations. An open cavity had been made in 98, obliteration in 44 and canal wall up surgery in 43 ears. All ears were now operated upon by the open method combined with ear canal reconstruction and mastoid obliteration. Mastoid cholesteatoma was found in 50% of the open cavities and in 63% of intact canal wall ears, while 80% of the obliterated ears showed mastoid retraction pockets with cholesteatoma. Semicircular canal fistulae occurred in all groups, most frequently in open cavities (11%). During the follow-up period after revision (average 5 years) 3% were reoperated upon because of a new cholesteatoma. In the whole series, average hearing levels were slightly better postoperatively and in 34% of the ears the A-B gap was 20 dB at most. The main reason for failure after primary surgery was inadequate mastoid and epitympanic bone work and failure to obliterate the medial parts of the cavity thoroughly. 相似文献

开放式乳突切开+鼓室成形术是一种治疗中耳胆脂瘤和慢性化脓性中耳炎等疾病的有效外科手术技术,旨在彻底清除病灶,从而达到干耳、促进病灶引流、避免颅内外并发症发生的目的。但手术遗留的大乳突空腔可能导致术耳反复流脓、术后需定期清理痂皮、与温度变化有关的前庭功能紊乱、继发术腔感染和隐形助听器佩戴不方便等问题,严重影响患者的生活质量。因此,乳突缩窄术对提高开放式乳突切开+鼓室成形术后疗效是非常重要的。随着医学技术的进步和材料科学的不断发展,越来越多的材料被临床医生应用到乳突缩窄术的临床实践当中,但各种材料的取材方式、组织量、是否容易存活和吸收等特点各不相同,各有优缺点。因此,论文就乳突缩窄术在开放式乳突切开+鼓室成形术中的应用及乳突填塞材料的选择进行综述。 相似文献

Long-term results of surgery for childhood cholesteatoma. 总被引:3,自引:0,他引:3
The study includes 54 cholesteatomatous ears in 50 children aged 16 years or less. The mean follow-up period after surgery was 7.1 years. In 26% of the ears the cholesteatoma was 'huge' involving the middle ear and the attic and filling the entire mastoid air cell system. A patient had lateral sinus thrombophlebitis. Patients with large cholesteatomas underwent canal wall down mastoidectomy with simultaneous tympanoplasty and, in most cases, cavity obliteration. Limited cholesteatomas were removed using either intact canal wall mastoidectomy or tympanotomy approach. Recurrence rate (including both residual and recurrent cholesteatomas) for the total series was 15% and 12% for the 50 cases undergoing one-stage surgery. Serviceable hearing (< or = 30 dB) was achieved in 57% of the ears. A reoperation was necessary in 26% and a third operation in 2%. At last follow-up examination, 94% of the ears had intact tympanic membranes but 4 patients (8%) suffered from cavity-related problems. Possible reasons for the disappointing results of surgical treatment for childhood cholesteatoma are discussed. 相似文献
