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.

AbstractObjectives:To describe the clinical features of external auditory canal cholesteatoma, and to assess the outcome following bony meatoplasty with tragal cartilage and perichondrium graft repair.Methods:A retrospective review was carried out, comprising all patients with external auditory canal cholesteatoma who presented between January 2007 and December 2011. Patients underwent pre-operative audiometry and computed tomography imaging of the temporal bones, before undergoing bony meatoplasty via a postauricular incision. Pre- and post-operative comparisons were made of patients' otological symptoms and the otoscopic appearance of the external ear canal.Results and conclusion:Eight patients were included in the analyses. The median age of patients was 46.5 years (range 14–68 years), with a male to female ratio of 1:1. The median length of follow up was 16 months. The most common presenting features were unilateral otalgia and purulent otorrhoea. All patients had relatively advanced disease at presentation, with erosion of the temporal bone. All patients underwent bony meatoplasty via a postauricular approach to eradicate the disease. Bony meatoplasty was successful in the definitive management of external ear canal cholesteatoma.

<p class="abstract">The external auditory canal can sometimes present with unique pathology since it is a vibrant environment possessing a variety of anaomical structures including bone, cartilage, skin, ceruminous glands and fibro-collagen tissues. Nodular fasciitis is an intriguing entity which rarely presents in the external ear canal as a growth. The diagnosis is made only through histopathological confirmation after ruling out similar benign or malignant lesions including ceruminoma, granuloma or carcinoma. Fasciitis being of fibrous origin has propensity to recur wherein management becomes more challenging. This is a clinical profile of a case of recurrent nodular fasciitis which was surgically managed and followed up with no further recurrence.</p>

Prolonged Contact

Exostosis of the external ear canal is a disease unique to man. It has been identified in prehistoric man, affecting the aborigines of the North American continent. Aural exostoses are typically firm, sessile, multinodular bony masses which arise from the tympanic ring of the bony portion of the external auditory canal. These growths develop subsequent to prolonged irritation of the canal. The large, primitive jaw of prehistoric man placed great mechanical stress on the tympanic ring. Chronic aural suppuration seen in the preantibiotic era was soon followed by exostoses. Today, prolonged contact of the external ear canal with cold sea water is the most prevalent cause (aquatic theory). As a result the disease is now essentially limited to coastal regions. In this way we have seen exostoses appear in different stages of the evolution of man as a result of mechanical, chemical and now thermal irritation. The author is an otolaryngologist in a coastal region. In examining 11,000 patients during a ten-year period, 70 cases of symptomatic exostoses of the external auditory canal were identified. The incidence of exostoses was found to be 6.36 per 1,000 patients examined for otolaryngologic disease. It is a predominantly male disease. The development of these “irritation nodules” is painless until the tenth year of aquatic exposure to irritation, when symptoms of obstruction occur. The hearing loss associated with exostoses is usually a conductive type, secondary to occlusion of the canal by impacted cerumen or acute external otitis. The results of studying the thermal characteristics of the body of water used for such aquatic activities is presented.

Specific Symptoms

External auditory canal cancer is a rare disease which can be treated by surgery or chemoradiation. The most common histological type is squamous cell carcinoma, but rare types such as adenocarcinoma have been reported and are thought to be derived from the ceruminous glands. Here, we present a case of ceruminous adenocarcinoma, not otherwise specified (NOS) in the external auditory canal. A 72-year-old woman was referred to our department with discomfort due to a mass in the external ear canal. No typical symptoms of malignancy, such as pain or bleeding, were noted at the initial examination. The patient underwent a total excision under local anesthesia as a diagnostic treatment. She was diagnosed with ceruminous adenocarcinoma, NOS based on the results of immunostaining of the excised specimen, and is currently being followed up as an outpatient. Adenocarcinoma is thought to originate from the cerumen glands of the ear canal and the lack of specific symptoms may make it difficult to differentiate it from benign tumors. Although adenocarcinoma, NOS has been reported in the head and neck region, there have been no reported cases occurring in the external ear canal, and to the best of our knowledge, this is the first report.

Canal Wall Reconstruction

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.

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.
