OBJECTIVE: To provide an estimate of the reliability of a preventive surgical approach named lateral attic reconstruction (LAR) technique for the treatment of Type II epitympanic retraction pockets. STUDY DESIGN: From a cohort of 25 adult patients presenting with a Type II epitympanic retraction pocket, 2 groups were randomly formed: a first one, with 15 patients who underwent LAR technique, and a second one, in whom (10 patients) only observation was planned and was therefore used as control. SETTING: University hospital as tertiary referral center. PATIENTS: Selection criteria for composing the 2 groups of study were the presence of a Type II epitympanic retraction pocket and a normal audiogram. INTERVENTION(S): The surgical procedure (LAR) consisted of a retroauricular approach, removal of a small piece of tragal cartilage, cleansing of the epitympanic pocket until denudation of the ossicular components, and placement of the cartilage graft to reconstruct the lateral epitympanic wall. MAIN OUTCOME MEASURE(S): All the patients were controlled at different postoperative or postobservation times (1, 3, 6, and 12 mo) via otomicroscopic examination, pure-tone audiometry, and tympanometry. RESULTS: All operated patients showed a normal anatomic pattern starting from the first postoperative control (1 mo) with a normal or near-normal hearing threshold and a Type A or As tympanogram in most cases. CONCLUSION: Lateral attic reconstruction technique has proved to be a reliable preventive technique for impeding a Type II epitympanic retraction pocket to worsen because it was observed in a percentage, although small (33.3%), of patients in whom a wait-and-scope policy was applied. 相似文献

While the hearing outcome of patients undergoing a tympanoplasty with canal reconstruction is generally thought to be inferior to that of patients undergoing a canal-up tympanoplasty, a direct comparison of these two procedures, performed by the same operator, has not been reported. Consequently, we compared the hearing outcomes of these two techniques and discussed the postoperative complications that could accompany the procedures. Hearing was evaluated in 52 ears with middle ear cholesteatoma. Using the postsurgical hearing result assessment criteria published by the Japanese Society of Otology in 2000, hearing was then evaluated again at least 6 months after surgery. When the data was analyzed according to the type of operation, the success rates (as determined using the above assessment criteria) were 78.6% for type I, 88.5% for modified type III, and 50.0% for modified type IV. The success rate for the modified type III operations was superior to that of the modified type IV operations, and the incidence of a postoperative air-bone gap in the type IV tympanoplasties was significantly larger than that in other groups. Procedures involving external auditory canal surgery can be particularly problematic for the treatment of cholesteatoma. In this series, the same author (KH) performed all the canal-up tympanoplasty procedures that took place during 1990-1996, and all other tympanoplasties, mainly canal reconstruction procedures, that took place during 1998-2001. The success rate was 68.4% (13/19) for the canal-up tympanoplasties, 100% (8/8) for the atticotomies and 76% (19/25) for the canal wall reconstructions. The postoperative success rate in the atticotomy group was significantly higher than the rates of the other groups. Among the canal reconstructive tympanoplasty procedures, a second exploratory surgery was performed in 15/24 cases, and residual cholesteatoma was observed in 3 cases. The major postoperative complications were epitympanic pocket formation (12/24) and taste disturbances, caused by chordal damage (2/24). These findings indicate that tympanoplasties with canal reconstruction improve the hearing outcome, compared with the outcome of canal-up tympanoplasties. However, epitympanic retraction pocket formation, resulting in recurrent cholesteatoma, is a possible complication of both surgical procedures, and new approaches or techniques should be sought to minimize such postoperative changes. 相似文献

This study analyzes the morphological and hearing results obtained with cartilage tympanoplasty in retraction pocket, blunting and tympanic membrane lateralization, and cholesteatoma surgeries. Results obtained 3 years postoperatively in 80 patients operated on with cartilage reinforcement of the tympanic membrane (TM) were compared with those obtained 3 years postoperatively in 100 patients operated on with fascia or perichondrium TM reinforcement. Retraction pocket recurrence was found in the patients operated on with fascia or perichondrium in 24% of cases and only in 8% of cases in patients operated on with partial tympanic membrane cartilage reinforcement. No recurrence was found in patients operated on with a total reinforcement of the TM. Cartilage tympanoplasty with skin graft covering the bony external auditory canal (EAC) was performed in 6 cases of severe blunting and/or tympanic membrane lateralization. 3 years post-operatively, good morphological and functional results were obtained in 3 cases. One or two staged ICW procedures were performed in 390 adult patients (416 ears) suffering from a non operated middle ear cholesteatoma. Recurrent and residual cholesteatoma rates were evaluated. Cholesteatomas were operated on with removing the malleus, reinforcing all the tympanic membrane with cartilage and performing an ossiculoplasty with hydroxylapatite prosthesis. The results were compared to those obtained in ICW cholesteatoma surgery with preserving the malleus manubrium, partially reinforcing the eardrum with cartilage and predominantly using an ossicle to perform the ossiculoplasty. Removing the malleus and reinforcing the whole tympanic membrane with cartilage statistically reduced the cholesteatoma recurrence rate for the ICW procedure. This technique, using hydroxylapatite prosthesis for ossiculoplasty gives good hearing results. 相似文献

OBJECTIVE: To evaluate the surgical outcome in patients who have undergone mastoid and epitympanic obliteration technique. STUDY DESIGN:: Retrospective review. SETTING: Tertiary care referral center. PATIENTS: The study group included 151 patients with cholesteatoma who underwent mastoid and epitympanic obliteration technique. This technique was applied to cases who had a strong chance of recurrent retraction pocket and cholesteatoma formation, including those patients with an adhesive drum indicating poor eustachian tube function (n = 52) and patients with a destructive scutum (n = 68). Thirty-one patients had both an adhesive drum and a destructive scutum. INTERVENTION: The connection between the mastoid cavity and the middle ear was blocked by obliterating the epitympanum and antrum with bone pate and the remaining mastoid cavity with abdominal fat. MAIN OUTCOME MEASURES: The postoperative drum state, the incidence of retraction pocket formation and cholesteatoma recurrence, the surgical complications of obliteration, and the hearing outcome. RESULTS: In 114 of 151 patients (75.4%), the middle ear was well healed and well aerated. The retraction pocket formation or cholesteatoma recurrence did not develop in any subject. Postauricular skin depression was the most common complication of this technique (n = 31 [20.5%]). In three patients (2.0%), the bone pate used for obliteration was infected. Of the 56 cases who underwent a staged operation to regain their hearing, 37 resulted in a postoperative air-bone gap less than 20 dB hearing level. CONCLUSION: Mastoid and epitympanic obliteration is an effective option for preventing a retraction pocket and cholesteatoma recurrence in patients with a poorly functioning eustachian tube or a defective scutum, while preserving the same advantage of the canal wall up technique. 相似文献

"Three cartilages" technique in intact canal wall tympanoplasty to prevent recurrent cholesteatoma 总被引:1,自引:0,他引:1
E Chiossone 《The American journal of otology》1985,6(4):326-330
Residual cholesteatoma is the consequence of leaving squamous epithelium in the mastoid and middle ear cleft. It has been demonstrated that the only effective way to reduce the risk of epidermoid cyst neoformation is meticulous and radical removal of cholesteatoma matrix and staging of the operation, regardless of whether a closed or open mastoid cavity tympanoplasty technique has been performed. Recurrent cholesteatoma usually occurs after intact canal wall tympanoplasty secondary to middle ear, attic, and mastoid retraction of the graft, especially in cases with destruction of the scutum or absence of malleus and incus; this is still considered a major problem with this surgical technique. During the last five years we have been performing a procedure we have developed to avoid this retraction. Concave autogenous cartilage from the upper part of the concha auriculae trimmed in three pieces to protect attic, mastoid, and middle ear for graft retraction has been successfully used in 106 surgical procedures. This study describes the surgical technique and analyzes the anatomic and hearing results. 相似文献

The authors review 1,939 chronic ear surgeries in which 1,556 underwent some form of tympanic membrane grafting. The overall take rate was 93%. There was no selection of cases with regard to presence of infection, cholesteatoma, polyps, or granulation tissue at the time of surgery. There appeared to be no difference in the take rate based upon age of the patient, presence of infection, or cholesteatoma. Autogenous and homograft fascia performed well and there was no significant difference in take rate. Complications were minimal and were related more to the disease process than the grafting technique per se. In addition to reviewing the long-term follow-up of the original technique the authors present a method of dealing with tympanic membrane retraction pockets. Called a cartilage tympanoplasty this procedure incorporates a large piece of full thickness tragal cartilage with attached perichondrium into the substance of the tympanic membrane. With 2 years follow-up at this writing, this procedure has markedly reduced postoperative retraction pockets and recurrent cholesteatoma. 相似文献

中耳乳突炎性改变对人工耳蜗置入的影响 总被引:2,自引:0,他引:2
目的:探讨中耳乳突炎性改变对人工耳蜗置入术的影响。方法:9例行人工耳蜗置入术患者均伴有中耳乳突炎性改变。1例乳突根治术后Ⅱ期行人工耳蜗置入及应用耳廓软骨一软骨膜复合物重建并加强后鼓室外侧壁及外耳道后壁;1例慢性中耳炎伴鼓膜穿孔Ⅰ期行人工耳蜗置入及应用耳廓软骨一软骨膜复合物重建鼓膜;3例隐性中耳乳突炎,Ⅰ期行改良乳突开放术并人工耳蜗置入术;3例硬化型乳突伴鼓室粘连,Ⅰ期行鼓室探查并人工耳蜗置入术;1例慢性中耳乳突炎伴松弛部内陷袋形成,Ⅰ期行上鼓室开放及软骨一软骨膜复合物重建上鼓室外侧壁并人工耳蜗置入术。结果:术中所有的电极均顺利置入,并经术中检测电极完好,电阻测试效果满意。术后伤口均甲级愈合,1个月后均开机成功。随访无并发症。结论:对于慢性中耳乳突炎的患者,若欲行Ⅱ期人工耳蜗置入术,Ⅰ期中耳乳突手术应尽可能保留相关解剖结构。对于隐性中耳乳突炎的患者在确保鼓窦乳突、上鼓室、咽鼓管口三处引流均通畅的前提下可行Ⅰ期人工耳蜗置入。对于病变局限的上鼓室胆脂瘤,有经验的术者可以选择Ⅰ期手术,但一定要慎重。感染因素很可能在乳突汽化不良及不明原因先天性感音神经性聋的发病中起着重要的作用。对于乳突硬化、乙状窦前移严重的患者可选择经外耳道鼓岬开窗。对于人工耳蜗置入术时的鼓膜修补术,上鼓室外侧壁或外耳道后壁重建选择软骨一软骨膜复合物可以提高成功率,加固鼓膜避免内陷及电极脱出。 相似文献

Objectives: We reviewed surgical results of canal wall-down tympanoplasty (CWDT) with soft posterior meatal wall reconstruction (SWR) for acquired cholesteatoma (AC), and identified factors associated with surgical outcomes.Methods: Results from 119 ears with AC (pars flaccida, n?=?99; pars tensa, n?=?20) that underwent CWDT with SWR were retrospectively reviewed. We defined postoperative balloon-like retraction (PBR) with web formation, which needed reoperation to clean accumulated cerumen, as postoperative deep retraction pocket (PDRP).Results: Residual cholesteatoma was found in 11 ears (9.2%). Seven residual cholesteatomas were treated with outpatient operation. Seven ears (5.9%) showed PDRP. A transcanal approach was applied to all PDRPs. Postoperative mastoid reaeration was observed in 57 ears (47.9%). No factors significantly associated with residual cholesteatoma or PDRP were identified. The frequency of postoperative mastoid reaeration was significantly higher among cases with young age (<50 years), stage I cholesteatoma, or type I ossiculoplasty.Conclusion: CWDT with SWR showed low rates of residual cholesteatoma or postoperative deep retraction pocket (PDRP). Most residual cholesteatomas and PDRPs could be dealt with using a minimally invasive procedure. Young age, stage I cholesteatoma, and type I ossiculoplasty were associated with postoperative mastoid reaeration. This procedure seems fully feasible for surgical treatment of AC. 相似文献
