AbstractBackgroundExternal auditory canal exostoses are known to occur in patients who engage in cold-water sports. Although the majority of patients with exostosis remain asymptomatic, larger lesions can cause wax impaction, conductive hearing loss and predispose to recurrent otitis externa.ObjectiveA novel technique is described of using a piezo saw to excise exostoses that are symptomatic. The piezo saw is used to perform various procedures, but its use in removing exostoses has not been described in the literature.ConclusionExcision of exostoses of the ear canal using a piezo saw is a safe technique and patients have a speedy recovery. This paper describes a new technique for removing exostoses.

Although the hearing loss of patients with Treacher Collins syndrome is well documented, few studies have reported jointly on their hearing loss and ear pathology. This paper reports on the hearing loss and computerized tomography (CT) assessments of ear malformations in a large pediatric series of patients with Treacher Collins. Of the 29 subjects assessed by the Craniofacial Program between 1986 and 1990, paired audiologic and complete CT assessments were available for 23 subjects. The external ear canal abnormalities were largely symmetric, either bilaterally stenotic or atretic. In most cases, the middle ear cavity was bilaterally hypoplastic and dysmorphic, and ossicles were symmetrically dysmorphic or missing. Inner ear structures were normal in all patients. The majority of patients had a unilateral or bilateral moderate or greater degree of hearing loss and almost half had an asymmetric hearing loss. The hearing loss of all subjects was conductive, except for three whose loss was bilateral mixed. Two types of bilaterally symmetric hearing loss configurations, flat and reverse sloping, were noted. Conductive hearing loss in patients with Treacher Collins is mainly attributable to their middle ear malformations, which are similar for those of patients with malformed or missing ossicles.

This presentation reports a novel case of chronic lymphocytic leukaemia (CLL), presenting with an early cutaneous lesion within the external auditory canal, in a patient being assessed for conductive hearing loss. It has previously been reported that infiltrative CLL can involve the head and neck; however, isolated external ear canal involvement is rare. Given that the incidence of CLL in Australia is rising, this case highlights the importance of considering CLL as a differential diagnosis for presentations of unilateral conductive hearing loss.

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.

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.

The Relationship

The external auditory canal is not only a part of the external ear, but also an integral part of the human auditory system, which conducts and amplifies the sound wave. In the field of otosurgery, it is often the priority access to the tympanic cavity, and therefore it is necessary to clearly understand the features of its anatomy. The dimensions and anatomy of the external auditory canal are extremely variable: the length is 2–3,5 cm, the diameter ranges from 5-9 mm, it is somewhat curved in the horizontal and frontal planes and consists of a membranous cartilaginous part and a bony part, between which there is the most the bottleneck – the isthmus. The ear canal is covered with skin, the thickness and structure of which depends on the section of the ear canal. The membranous cartilaginous section contains sebaceous and sulfur glands. Studies identify several forms of the bony part of the ear canal: conical, hourglass-shaped, ovoid, reverse conical, and cylindrical. The endoscopic scale (CES) for the visibility of the tympanic membrane was also proposed for the convenience of assessment. It has been suggested that the shape of the external auditory canal is an etiological factor in chronic otitis externa. Unambiguous interpretations of the relationship between ear diseases and the shape of the external auditory canal have not yet been obtained, but modern developments tend to consider its importance in the development of ear diseases. Clinical observations show that certain anatomical forms of it may be involved in the pathogenesis of chronic inflammation, since they interfere with proper self-cleaning.

Conductive Hearing

Hearing loss must be divided into conductive hearing loss (CHL) and sensorineural hearing loss (SNHL). CHL is caused by sound not reaching the cochlear (abnormality of the ear canal, tympanic membrane, middle ear, or ossicles), whereas SNHL is a condition affecting the cochlear or auditory (eighth cranial) nerve. Hearing loss may be accompanied by other cardinal signs of ear disease, such as pain or discharge from the ear, vertigo, facial nerve palsy, and tinnitus, which guide the diagnosis. This chapter describes the approach to the patient with hearing loss.
