Hearing loss

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.

The case of a five year old boy who presented with a lower motor neurone facial nerve palsy secondary to primary non-Hodgkin’s lymphoma (NHL) of the middle ear is discussed. Any child who presents with a facial nerve palsy and conductive hearing loss requires thorough evaluation to exclude the possibility of temporal bone malignancy.

Keratosis obturans is characterized by the accumulation of desquamated keratinous material in the bony portion of the external auditory canal. Classically, it is reported to present with severe otalgia, conductive hearing loss and global widening of the external auditory canal. Extensive erosion of the bony meatus, with exposure of the facial nerve, has been previously reported, but no case of facial nerve palsy has as yet been published. We report the first published case, to our knowledge, of a unilateral facial nerve palsy secondary to neglected keratosis obturans.

A 15-year-old patient had unilateral double congenital cholesteatomas, one isolated to the mastoid and the other located in the petrous pyramid. The presenting symptoms were facial palsy and a conductive hearing loss on the affected side. The case is interesting, not only in that there were two isolated cholesteatomas in the same temporal bone, but also because of the combination of ossicular anomalies. The unusually early detection and surgical intervention in this instance suggest that similar cases of multicentric cholesteatomas may have occurred, but may have been concealed because of the later detection and possible linkage of the cholesteatomas. I would therefore emphasize Sheehy's recommendation that temporal bone radiography never be omitted where idiopathic facial nerve palsy exists.

A rare facial nerve anomaly was incidentally discovered whilst performing a tympanoplasty and ossicular reconstruction on a patient with an acquired unilateral conductive hearing loss. The nerve was seen to bifurcate and straddle a normal stapes superstructure as it ran posteriorly through the middle ear, a unique and as yet unreported combination. This case highlights the importance of vigilance regarding facial nerve anatomical variations encountered during middle-ear surgery thus avoiding inadvertent damage. The purported embryological mechanism responsible for such anomalies of the intra-tympanic facial nerve is discussed.

Salivary gland choristoma is an extremely rare middle ear pathology. We present the case of a 10-year-old girl with unilateral conductive hearing loss. Tympanotomy showed a nonspecific middle ear mass, absence of stapes, anomaly of incus, and displaced facial nerve. It was not possible to remove the mass completely. Histology confirmed salivary gland choristoma. The hearing in this case can be improved with a bone-anchored hearing aid.

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.

AbstractA three-generation family with Saethre-Chotzen syndrome and an isolated case are presented. The proband presented with conductive hearing loss. His mother and grandmother showed minor features of the syndrome including conductive hearing loss.Symptoms of the craniosynostosis syndromes can include stapes ankylosis, a fixed ossicular chain in a too small epitympanum, and small or even absent mastoids. The proband was treated with a boneanchored hearing aid (BAHA) instead of reconstructive middle ear surgery. Current literature on the results of ear surgery is reviewed. In general, reconstructive middle ear surgery should only be considered if congenital anomalies of the middle ear are the only presenting symptom. In cases with additional anomalies such as atresia of the ear canal or damage due to chronic ear infections, the outcome of reconstructive surgery to correct the anomalous ossicular chain is unsatisfactory. In such cases the BAHA is probably the best solution.

Up to 3 million people in Britain might be helped by hearing aids.1 2 Most are over 65 years of age, but some are infants. All should be referred to specialist centres for assessment as soon as possible. Hearing aids generally help most in disorders of the middle ear (conductive hearing loss); they can also help those with sensorineural and other forms of hearing loss. The use of an aid often needs to be supplemented by lip reading and other means of auditory training.1 3
