We conducted a retrospective study to compare the clinical characteristics of external auditory canal cholesteatoma (EACC) with those of a similar entity, keratosis obturans (KO). We also sought to identify those aspects of each disease that may lead to complications. We identified 6 patients in each group. Imaging studies were reviewed for evidence of bony erosion and the proximity of disease to vital structures. All 6 patients in the EACC group had their diagnosis confirmed by computed tomography (CT), which demonstrated widening of the bony external auditory canal; 4 of these patients had critical erosion of bone adjacent to the facial nerve. Of the 6 patients with KO, only 2 had undergone CT, and neither exhibited any significant bony erosion or expansion; 1 of them developed osteomyelitis of the temporal bone and adjacent temporomandibular joint. Another patient manifested KO as part of a dermatophytid reaction. The essential component of treatment in all cases of EACC was microscopic debridement of the ear canal. We conclude that EACC may produce significant erosion of bone with exposure of vital structures, including the facial nerve. Because of the clinical similarity of EACC to KO, misdiagnosis is possible. Temporal bone imaging should be obtained prior to attempts at debridement of suspected EACC. Increased awareness of these uncommon conditions is warranted to prompt appropriate investigation and prevent iatrogenic complications such as facial nerve injury.  相似文献

The purpose of this study is to evaluate the efficiency of conservative dilute vinegar therapy in the management of spontaneous external auditory canal cholesteatoma (EACC). From 2000 to 2007, 19 patients presented to our clinic with spontaneous EACC. EACC was divided into four grades based on the temporal bone computed tomography: grade I with flattening of bony external canal, grade II with partial destruction of inferior bony canal, grade III with total destruction of inferior bony canal and grade IV with bony destruction into the middle ear and mastoid cavity. Clinical findings and treatment results were recorded. Microscopic local cleansing and dilute vinegar therapy was conducted in the ears with grades I, II and III. Combined mastoid surgery and dilute vinegar therapy was conducted in four ears with stage IV. There were no recurrences after average of 31 months follow-up. Spontaneous EACC can be effectively controlled with dilute vinegar therapy after microscopic local cleansing. However, surgery must be considered in the cases which have involved the mastoid and middle ear. Dilute vinegar therapy in combination with microscopic local cleansing was effective in the management of spontaneous EACC. Dilute vinegar therapy is an easy, cost-effective, and home-based cleansing method to prevent EACC and promotes healing. However, long-term follow-up may reveal frequent recurrence of cholesteatoma debris and involvement of middle ear or mastoid cavity, and then meticulous debridement with skin graft or surgical intervention should be considered.  相似文献

The purpose of this study was to investigate the characteristics of external auditory canal cholesteatoma (EACC) in children through evaluation of the clinical and radiologic features as well as treatment outcomes. The clinical records were retrospectively reviewed for children under 15 years of age diagnosed with spontaneous EACC between March 2004 and December 2011. The clinical data of adults diagnosed with spontaneous EACC during the same period were evaluated to compare with EACC in children. Eight patients (3 males and 5 females) with pediatric EACC and 18 patients (7 males and 11 females, 20 ears) with adult EACC were included within the boundary of the study. The mean ages were 12.4 years (age range 9–15) for pediatric EACC and 49.8 years (age range 29–79) for adult EACC patients. Follow-up periods ranged from 8 to 86 months (mean 32.5 ± 8.62) in pediatric EACC and from 6 to 72 months (mean 22.2 ± 5.36) in adult EACC. Pediatric EACC, showed involvement most commonly in the posterior wall, while the inferior wall was most commonly involved in adult EACC. Pediatric EACC tended to show a more focal involvement and was not as extensive as adult EACC. Extension into the adjacent structures was similar in both groups, but bony destruction was more common in the adult group. Two children and eight adult patients were treated with surgery, but four adult cases needed more extensive surgical treatment because their disease was widely spread to included areas such as the mastoid segment of facial nerve and the temporomandibular joint. Six pediatric cases treated with conservative management showed no progression of disease on physical examination at the last visit, but two cases of adults progressed and required canaloplasty. Pediatric EACC shows less aggressive behavior compared to adult EACC. Adequate management may work better in pediatric than in adult EACC, even though the treatment modality is conservative management.  相似文献
