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.

Rate Of Growth

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.

Skin Coverage

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.

Veterinary Surgeon

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.

Ectopic Thyroid Tissue

<p class="abstract">An ectopic thyroid is a rare occurrence with a majority of ectopic thyroid tissue located in the lingual region or in the midline. The abnormal sites represent developmental defects in migration from the floor of the primitive foregut at the foramen caecum of the tongue to the final pre-tracheal position of the gland. A few cases of ectopic thyroid tissue have also been reported from sites seemingly unrelated to the normal development of the thyroid gland.  We report a case of ectopic thyroid in the external ear canal, which presented as a small reddish mass in the external ear canal. To the best of our knowledge, this is the first such reported case in literature and adds to the body of knowledge in such cases. Although such a finding is exceedingly rare, the authors recommend routine histopathology in all cases of polyps in the external canal and standard investigation for the status of the residual thyroid gland via isotope scans, ultrasonography or thyroid function tests.</p>
