Conductive Hearing

Cholesteatomas are found almost exclusively in the middle ear and mastoid. Occasionally this disease is seen in the external auditory canal. Cholesteatoma of the external auditory canal is a rare condition. Severe pain and profuse discharge associated with a normal eardrum and normal hearing are essential clinical features. In addition, we found facial paresis and conductive hearing loss in our case. Smaller cholesteatomas can be managed by frequent debridement in the office; larger lesions require surgical intervention. Surgery is successful in resolving otorrhea and relieving pain. In addition, our own experience has shown that surgery is successful in relieving facial paresis.

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

Conductive Hearing

The aim of this study is to increase awareness of rare presentations, diagnostic difficulties alongside management of conductive hearing loss and ossicular abnormalities. We report the case of a 13-year-old female reporting progressive left-sided hearing loss and high resolution computed tomography was initially reported as normal. Exploratory tympanotomy revealed an absent stapedius tendon and lack of connection between the stapes superstructure and footplate. The footplate was fixed. Stapedotomy and stapes prosthesis insertion resulted in closure of the air-bone gap by 50 dB. A review of world literature was performed using MedLine. Middle ear ossicular discontinuity can result in significant conductive hearing loss. This can be managed effectively with surgery to help restore hearing. However, some patients may not be suitable or decline surgical intervention and can be managed safely conservatively.

Conductive Hearing

The conductive SISI (short increment sensitivity index) test is an indirect procedure to estimate bone-conduction thresholds for middle ear pathology patients. A series of SISI tests are run, beginning at 20 dB S.L. and increasing in 10 dB S.L. steps, until a 100% SISI score is obtained. The following equation predicts the bone-conduction threshold: [Formula: see text] The results of 25 conductive SISI tests on a conductive hearing loss group indicate that the equation approximates the measured B.C. threshold. There was no statistical difference between the predicated B.C. thresholds (12.4 dB) and measured B.C. thresholds (10.4 dB) for the group.

We recorded auditory-evoked magnetic responses with a whole-scalp 122-channel neuromagnetometer from seven adult patients with unilateral conductive hearing loss before and after middle ear surgery. The stimuli were 50-msec 1-kHz tone bursts, delivered to the healthy, nonoperated ear at interstimulus intervals of 1, 2, and 4 seconds. The mean preoperative pure-tone average in the affected ear was 57 dB hearing level; the mean postoperative pure-tone average was 17 dB. The 100-msec auditory-evoked response originating in the auditory cortex peaked, on average, 7 msecs earlier after than before surgery over the hemisphere contralateral to the stimulated ear and 2 msecs earlier over the ipsilateral hemisphere. The contralateral response strengths increased by 5% after surgery; ipsilateral strengths increased by 11%. The variation of the response latency and amplitude in the patients who underwent surgery was similar to that of seven control subjects. The postoperative source locations did not differ noticeably from preoperative ones. These findings suggest that temporary unilateral conductive hearing loss in adult patients modifies the function of the auditory neural pathway. (Otolaryngol Head Neck Surg 1998;119:125-30.)

Introduction. Despite modern radiological workup, surgeons can still be surprised by intraoperative findings or by the pathologist’s report.Materials & Methods. We describe the case of a 52-year-old male who was referred to our clinic with a single sided conductive hearing loss. He ultimately underwent middle ear exploration and excision of a middle ear tumour followed by second look and ossiculoplasty a year later.Results. Though preoperative CT and MRI scanning were suggestive of a congenital cholesteatoma, the pathologist’s report diagnosed a middle ear adenoma.Discussion. Middle ear glandular tumors are extremely rare and, despite numerous histological techniques, continue to defy satisfactory classification. Most surgeons advocate surgical excision though evidence of the tumour’s natural course and risk of recurrence is lacking.

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.

Neuroendocrine adenoma of the middle ear (NAME) is a rare tumor. We report a case of NAME, the clinical and pathologic findings of which illustrate the biologic behavior of adenomatous tumors of the middle ear and their relationship with rare carcinoid tumors of the middle ear. A 29-year-old man presented with a history of recurrent otitis media, right conductive hearing loss, and aural fullness. The tumor was removed in its entirety. Otolaryngologists should be familiar with this unusual but important entity.

AbstractObjective:We present a technique which we have found useful for the management of congenital cholesteatoma extensively involving the middle ear.Case report:A five-year-old boy was presented to our department for management of a white mass on the right tympanic membrane. This congenital cholesteatoma extensively occupied the tympanic cavity. It was removed through an extended tympanotomy approach using our modified sleeve technique. The conventional tympanotomy approach was extended by gently separating the tympanic annulus from its sulcus in a circular manner. The firm attachment of the tympanic membrane at the umbo was not severed, in order to avoid lateralisation of the tympanic membrane.Conclusion:Although various operative techniques can be used, our modified sleeve tympanotomy approach provides a similarly sufficient and direct visualisation of the entire middle ear, with, theoretically, no possibility of lateralisation of the tympanic membrane and subsequent conductive hearing loss.
