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.

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.

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.

AbstractA case of bilateral progressive stenosis of both external auditory canals with resultant conductive hearing loss is presented. The stenosis revealed multifocal erosive and synechiant lichen planus. To our knowledge, this is the first reported case of lichen planus involvement of the external ear.

<p class="abstract">Neurofibromas are relatively common tumours of the nervous system, but only few cases involving the external ear have been reported. We are reporting here a case of a 30-year-old male with neurofibroma of the external auditory canal. The primary complaint was cosmetic deformity and mild conductive hearing loss. There was total occlusion of the external auditory canal. The swelling was excised by postauricular approach. Surgery resulted in an superb purposeful and cosmetic outcome. Neurofibromas of the head and neck do not seem to be uncommon, however they seldom have an effect on the external ear and only a few such published reports are available.</p>

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.
