Congenital aural atresia is an ear malformation evident at birth, involving various degrees of failed external ear canal development. A true external ear canal is desirable, as devices that replace the canal are inconvenient and expensive. Therefore, an optimal surgical technique is required. Here, we review useful preoperative and operative techniques. Surgical correction is often not the preferred treatment; the hearing outcome is no better than the outcomes afforded by bone-conduction devices, and surgery may be associated with recurrence or complications such as meatal stenosis. Preoperative evaluation and appropriate management are important. Several means of preventing meatal stenosis are discussed in this review.

Objectives: To investigate posterior external ear canal wall reconstruction with a composite cartilage titanium mesh graft in canal wall down tympanoplasty and revision surgery for open mastoids.Study design: Retrospective case review.Setting: Tertiary referral centre.Methods: As a preliminary study, 15 selected patients underwent reconstruction of a posterior ear canal wall defect with titanium mesh. Large defects of the posterior external auditory canal wall, resulting from canal wall down tympanoplasty or present in revision surgery, were eliminated by reconstruction using a titanium mesh. The mesh was covered with conchal cartilage and attached to the cortical mastoid bone using 3-mm titanium screws.Results: All patients maintained a normal contour of the external ear canal, without depression, extrusion or infection. There were no failures, based on short-term post-operative controls. However, two procedures had to be revised due to incomplete coverage of the titanium mesh.Conclusions: This study shows that reconstruction of the posterior ear canal wall with a composite cartilage titanium mesh is a valuable method for preserving the morphology of the external auditory canal in selected cases. Problems occurring in canal wall down tympanomastoidectomy and radical cavities may therefore be avoided. However, long-term results have yet to be evaluated.

Objectives Feline otitis externa is a multifactorial dermatological disorder about which very little is known. The objective of this study was to map the prevalence of external ear canal disorders and the pathogens causing otitis externa in stray cats roaming around the region of Ghent, Belgium. Methods One hundred and thirty stray cats were randomly selected during a local trap–neuter–return programme. All cats were European Shorthairs. This study included clinical, otoscopic and cytological evaluation of both external ears of each cat. Prospective data used as parameters in this study included the sex, age and body condition score of each cat, as well as the presence of nasal and/or ocular discharge, and the results of feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) Snap tests. Results Remarkably, very few (sub)clinical problems of the external ear canal were found in the stray cat population. Malassezia species was by far the most common organism found in the external ear canals of the 130 stray cats. A total of 96/130 (74%) cats were found to have Malassezia species organisms present in one or both ears based on the cytological examination. No correlation was found between the parameters of sex, age, body condition score, the presence of nasal and/or ocular discharge and FIV and FeLV status, and the presence of parasites, bacteria or yeasts. Conclusions and relevance This study provides more information about the normal state of the external ear canal of stray cats. The ears of most stray cats are relatively healthy. The presence of Malassezia species organisms in the external ear canal is not rare among stray cats.

This paper assessed 300 surfboard riders, comprising 229 males and 71 females to determine the prevalence and rate of growth of exostoses in this population. A group of cold water swimmers and a control group were also examined. Significant obstruction, defined as two thirds or more occlusion of the ear canal was noted in 90 of the male surfers and 10 female surfers. This degree of occlusion was found in seven of the 32 cold water swimmers. A male surfer who has surfed regularly for 20 years or more has a one in two chance of developing significant obstruction of the external ear canal resulting from exostoses and this is a three in seven chance for females.

AbstractReports concerning the lesions of the skin coverage of the external ear canal in malignant external otitis (M.E.O.) are very few. To evaluate this problem, we studied the skin lesions of 45 skin biopsies from 40 M.E.O. patients, 23 from regions covering the osseous part of the ear structure, seven from the cartilaginous part of the external canal and 15 from both parts. The epidermis was normal in nine, thickened in 16, with acanthotic thickening and pseudoepitheliomatous hyperplasia in 20. In the dermis the amount of collagen was normal, but it was infiltrated by the inflammatory process. Acute inflammation was observed in 16 biopsies, subacute in 23, chronic in six. A mixture of acute and chronic changes was present in 18 biopsies. No major abnormalities of the vasculature could be detected. The distinguishing pathological feature of M.E.O. concerns the typical topographic distribution of the inflammation in the osseous part of the external ear canal.

Otitis externa is a common problem in primary care veterinary practice. While the diagnosis and treatment of disease is the responsibility of the attending veterinary surgeon, the veterinary nurse, as an integral part of the veterinary surgeon-led team, plays an important role in the investigation and management of disease. Veterinary nurses are more than capable of assessing the external ear canal both macroscopically and cytologically to help the veterinary surgeon to make a diagnosis. Client facing nurse communications can help with the administration of therapy, provide owner support during treatment to increase compliance and help with follow-up assessments.
