Thirty-seven cases of ceruminous gland tumors of the external auditory-canal are presented. These are rare tumors, each of which has different clinical characteristics. Six adenomas are reported which are benign and require only local excision for long-term cure. Two muco-epidermoid carcinomas, a type not previously reported, are presented. The muco-epidermoid carcinoma tends to iecur locally and radical excision is necessary for control. The most common glandular tumor of the external auditory canal is the adenoid cystic carcinoma. Twenty-four are reported. Pain is the hallmark of this tumor. The long clinical course ultimately results in death if the tumor is not radically removed at the earliest possible time. Radiation is ineffective. Treatment recommended is (1) wide excision of the external auditory canal, (2) extensive radical mastoidec-tomy, and (3) total parotidectomy and mandibular condylectomy. Five cases of adenocarcinoma are presented. Four were dead from local invasion and distant metastasis within four years, and the fifth was lost to follow-up. Careful histologie evaluation and classification of the type of tumor is necessary to predict the natural history and select the proper treatment. Local excision is curative for the benign adenoma. For the three types of carcinoma described, the surgeon must not hesitate to do the radical operation for the early lesion, because it is in the early stages that the opportunity to produce the cure exists. 相似文献

Tumors of external auditory canal are rare and malignant neoplasms of external auditory canal are uncommon. We report two
cases of carcinoma of external auditory canal. Primary carcinomas of the external auditory canal are rare, the incidence being
approximately two cases per one million per year. Incidence in females is more than males (1). The cases are usually diagnosed
late because of the absence of significant presenting complaints. 相似文献

Schwannomas of the external auditory canal are extremely rare and only a few cases have been reported in the literature. Herein, we report a case of schwannoma of the external ear canal in a 41-year male. Clinicians should consider the possibility that the schwannoma may originate in the external auditory canal mimicking other more frequently observed lesions. 相似文献

In the ear, paragangliomas are commonly found in the tympanic cavity or in juglar bulb. We, here, present a case of paraganglioma
originating from the external auditory canal as it has not been reported in the world literature. The clinico-pathologic features
of such a case has been described. 相似文献

Schwannomas are uncommon tumors of the external auditory canal. In the English literature, very few cases of schwannomas originating in the external auditory canal were reported. In this report, we described a 44-year-old patient who presented with external auditory canal mass which was managed by local excision. The clinical and histologic features, the differential diagnosis, and the treatment of external auditory canal schwannoma is discussed. 相似文献

We report the first documented case of reticulohistiocytoma of the external auditory canal in a 15-year-old male. Reticulohistiocytoma is a rare diagnosis in children. Reticulohistiocytoma, a benign lesion, belongs to a family of histiocytosis disorders which range from benign to malignant. Although histiocytic disorders are uncommon, they should be included in differential diagnosis of pediatric aural polyps. 相似文献

OBJECTIVE: To evaluate the outcome of surgery for cancer of the external auditory canal and relate this to the Pittsburgh staging system used both on squamous cell carcinoma and non-squamous cell carcinoma. DESIGN: Retrospective case series of all patients who had surgery between 1979 and 2000. Median follow-up was 47 months (range, 2-148 months). Data on age, sex, symptoms, TNM status, histopathological diagnosis, surgery, adjunctive therapy, sequelae, recurrence, and status at follow-up were obtained. SETTING: An ear, nose, and throat department in an ambulatory and hospitalized care center. PATIENTS: Ten women and 10 men with previously untreated primary cancer. Median age at diagnosis was 67 years (range, 31-87 years). Survival data included 18 patients with at least 2 years of follow-up or recurrence. INTERVENTION: Local canal resection or partial temporal bone resection. MAIN OUTCOME MEASURE: Recurrence rate. RESULTS: Half of the patients had squamous cell carcinoma. Thirteen of the patients had stage I tumor (65%), 2 had stage II (10%), 2 had stage III (10%), and 3 had stage IV tumor (15%). Twelve patients were cured. All patients with stage I or II cancers were cured except 1 with adenoid cystic carcinoma. No patients with stage III or IV cancer were cured. All recurrences developed in patients with incompletely resected tumors. CONCLUSIONS: The outcome was related to the stage of disease, suggesting that the Pittsburgh staging system is useful also in patients with non-squamous cell carcinoma. Patients with early cancer benefited from a less aggressive surgical approach, while survival was poor in patients with advanced cancer with incompletely resected tumors despite adjuvant radiotherapy. 相似文献

BACKGROUND: Inherited isolated bilateral atresia of the external auditory canal is rare. Ear canal surgery procedure is difficult. METHODS: Basing on a case report of a family with inherited isolated bilateral atresia of the external auditory canal in 4 cases the way of preoperative diagnostics including human genetics and our surgical concept is described. RESULTS: Resulting clinical findings showed complete epithelialization of the ear canal and ear drum with slight conductive hearing loss. CONCLUSIONS: Canaloplasty in atresia can be easily and successfully accomplished by our modified technique. 相似文献

Denosumab is the world's first human monoclonal antibody for the treatment of osteoporosis and shares an active pathway with bisphosphonates, strongly suppressing osteoclast activities. This is the first case report describing a possible relationship between the development of osteonecrosis of external auditory canal and denosumab administration. We herein report an 81-year-old woman diagnosed with left osteonecrosis of external auditory canal who had a history of denosumab administration. She underwent left radical mastoidectomy due to being refractory to conservative treatment. No major complications or recurrence were observed in the left ear after surgery, but bone erosion in the right ear has continued to progress slowly despite the cessation of denosumab administration. Otolaryngologists should be aware of the association between osteonecrosis of external auditory canal and denosumab administration and consider performing long-term observation even after cessation. 相似文献

Gunshot injuries in the periauricular region can result in massive tissue distortion and destruction. The soft tissue effects can be so dramatic that otologic abnormalities can be initially overlooked, especially by non-otolaryngologists. Delayed stenosis or complete closure of the external auditory canal can occur. We present two cases of post-traumatic ear canal atresia that were initially overlooked by non-otolaryngologists, until secondary plastic reconstructive operations were performed in which preauricular skin incisions entered into large canal cholesteatomas. These canal cholesteatomas resulted from total obstruction of the external auditory canal after trauma. 相似文献
