1/94. Multifocal cholesteatoma of the external auditory canal following blast injury.Posttraumatic cholesteatoma of the external auditory canal is a rare condition that may present years after the original injury. A unique case of multifocal cholesteatoma of the external auditory canal following blast injury is presented and discussed.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
2/94. An aural myiasis case in a 54-year-old male farmer in korea.A 54-year-old male farmer residing in Chunchon, korea, complaining of blood tinged discharge and tinnitus in the left ear for two days, was examined in August 16, 1996. Otoscopic examination revealed live maggots from the ear canal. The patient did not complain of any symptoms after removal of maggots. Five maggots recovered were identified as the third stage larvae of Lucilia sericata (diptera: Calliphoridae). This is the first record of aural myiasis in korea.- - - - - - - - - - ranking = 0.16666666666667keywords = canal (Clic here for more details about this article) |
3/94. A simple reconstructive procedure for radiation-induced necrosis of the external auditory canal.Localized necrosis of the bone, cartilage, and soft tissue of the external auditory canal is an uncommon side effect of radiotherapy to the parotid region. Five patients developed late onset skin necrosis of a quadrant of the ear canal secondary to an underlying osteoradionecrosis of the tympanic ring. We report a one-stage procedure to excise the necrotic tissue and replace it with a local rotational flap derived from the post-auricular skin. Otological side effects of radiotherapy are discussed.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
4/94. Carabid beetle invasion of the ear in Oman.Two cases of human ear invasion by a predaceous beetle, Crasydactylus punctatus Guerin (Coleoptera; Carabidae), are reported from the Sultanate of Oman. The first case was that of a 35-year old woman who suffered a severe otologic injury caused by the biting and chewing of the external auditory canal and the tympanic membrane. The beetle then entered the middle ear and caused sensorineural hearing loss. The second case involved a 22-year-old male from whose ear a specimen of the same species was successfully removed after it was immobilized with 10% lidocaine spray. These cases are presented with discussion.- - - - - - - - - - ranking = 0.16666666666667keywords = canal (Clic here for more details about this article) |

A clinical case, that is only the second in the English literature, is presented. The potential pathogenesis and its treatment options are discussed.- - - - - - - - - - ranking = 0.83333333333333keywords = canal (Clic here for more details about this article) |
6/94. Intraosseous ganglion of the temporomandibular joint presenting with otorrhea.A ganglion cyst of the temporomandibular joint is a rare entity that commonly presents as a minimally tender, preauricular mass. This benign cystic lesion, which is lined by synovium and can be found in association with other joints, occasionally erodes adjacent bone to form an intraosseous ganglion. We discuss an unusual case of an intraosseous temporomandibular ganglion cyst that presented with bloody otorrhea. Examination revealed an external auditory canal mass with radiographic evidence of temporal bone erosion. The cyst was excised using a combined approach to the glenoid fossa and mastoid. The management principals of this case and a pertinent review of the literature are included.- - - - - - - - - - ranking = 0.16666666666667keywords = canal (Clic here for more details about this article) |
7/94. Defects of the external auditory canal: a new reconstruction technique.This report describes the clinical and radiographic findings together with surgical management of temporomandibular joint contents herniation through the tympanic plate of the external auditory canal. Two patients are reported. A review of the literature is presented, including a brief discussion of the embryological development of the external auditory canal. Excluding infection, trauma or neoplasm, the defect in the tympanic plate of the external auditory canal represents a developmental aberration with failure of the foramen of Huschke to close during development. A pre-auricular approach with insertion and fixation of an onlay polyethylene implant to prevent prolapse of the peri-articular tissues into the ear canal is presented and described.- - - - - - - - - - ranking = 1.3333333333333keywords = canal (Clic here for more details about this article) |
8/94. What inner ear diseases cause benign paroxysmal positional vertigo?Benign paroxysmal positional vertigo (BPPV) originating from the posterior semicircular canal (pSCC) is a common vestibular disorder that is easy to diagnose and usually easy to treat. The majority of patients with BPPV have no known inner ear disease; they have "primary" or "idiopathic" BPPV. However, a minority does have objective evidence of an inner ear disease on the same side as the BPPV and this group has "secondary" or "symptomatic" BPPV. Previous publications differ on the prevalence of secondary BPPV and about the types of inner ear diseases capable of causing it. In order to determine what proportion of patients have secondary as opposed to primary BPPV and which inner ear diseases are capable of causing secondary BPPV, we searched our database for the 10-year period from 1988 to 1997 and found a total of 2847 patients with BPPV. Of these, 81 (3%) had definite pSCC-BPPV secondary to an ipsilateral inner ear disease. Sixteen had Meniere's disease, 24 had an acute unilateral peripheral vestibulopathy, 12 had a chronic unilateral peripheral vestibulopathy, 21 had chronic bilateral peripheral vestibulopathy and 8 had unilateral sensorineural hearing loss. It seems that any inner ear disease that detaches otoconia and yet does not totally destroy pSCC function can cause BPPV and that a case can be made for audiometry and caloric testing in all patients with BPPV.- - - - - - - - - - ranking = 0.16666666666667keywords = canal (Clic here for more details about this article) |
9/94. External and middle ear trauma resulting from ear impressions.When taking an impression of the external ear canal and ear, the audiologist is engaged in an invasive procedure whereby a foreign body is first placed into the ear canal and then removed. There is always an element of risk for significant medical problems when a clinician is performing an invasive procedure. Although some minor patient discomfort and, at times, some slight trauma to the ear canal occur when taking ear impressions, the incidence of significant trauma to the external or middle ear appears to be low. The purpose of this report is to provide some illustrative cases of significant external and middle ear trauma as a result of taking impressions of the external ear. Audiologists are advised to develop and implement an appropriate risk management program for taking ear impressions to reduce the potential risks associated with this procedure to their patients and to their practices.- - - - - - - - - - ranking = 0.5keywords = canal (Clic here for more details about this article) |
10/94. External cholesteaoma and fibrous dysplasia of temporal bone.cholesteatoma is a disease that involves almost exclusively the middle ear structures and the mastoid bone. In rare cases it involves the external auditory canal. The author would like to present case report of a patient affected by external ear canal cholesteatoma associated to fibrous dysplasia of the temporal bone. The problems related to the pathogenesis and the diagnosis of the disease are presented and discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = canal (Clic here for more details about this article) |
