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.

Tomography Scanning

Round window atresia (RWA) is an uncommon condition and can result in a conductive hearing loss. Two cases of nonsyndromal bilateral RWA in 2 members of the same family are reported. Both cases presented with a conductive hearing loss of 20 to 30 dB. High-resolution computed tomography scanning was used to diagnose the condition. The patients were rehabilitated with hearing aids. Review of the literature has shown disappointing results in hearing improvement with cochlear fenestration in an attempt to address this condition. Patients presenting with unexplained conductive hearing loss should be offered computed tomography scanning. The cases we report add to the literature to benefit future patients in preoperative counseling and better inform management.

This study aimed to determine the measurements of the cochlea among healthy subjects and hearing deafness subjects using a High Resolution Computed Tomography (HRCT). A total of 230 temporal bone HRCT cases were retrospectively investigated in the period spanning from 2011 to 2015. Three 64-slice units were used to examine patients with clinical complaints of hearing loss conditions at three Radiology departments in Khartoum, Sudan. For the control group (A) healthy subjects, the mean width of the right and left cochlear were 5.61±0.40 mm and 5.56±0.58 mm, the height were 3.56±0.36 mm and 3.54±0.36 mm, the basal turn width were 1.87±0.19 mm and 1.88 ±0.18 mm, the width of the cochlear nerve canal were 2.02±1.23 and 1.93±0.20, cochlear nerve density was 279.41±159.02 and 306.84±336.9 HU respectively. However, for the experimental group (B), the mean width of the right and left cochlear width were 5.38±0.46 mm and 5.34±0.30 mm, the height were 3.53±0.25 mm and 3.49±0.28mm, the basal turn width were 1.76±0.13 mm, and 1.79±0.13 mm, the width of the cochlear nerve canal were 1.75±0.18mm and 1.73±0.18mm, and cochlear nerve density were 232.84±316.82 and 196.58±230.05 HU, respectively. The study found there was a significant difference in cochlea’s measurement between the two groups with a p-value < 0.05. This study had established baseline measurements for the cochlear for the healthy Sudanese population. Furthermore, it found that HRCT of the temporal bone was the best for investigation of the cochlear and could provide a guide for the clinicians to manage congenital hearing loss.

Conductive Hearing

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.

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.

AbstractObjective:We report an extremely rare case of primary otoscleroma.Method:We present a case report and a review of the world literature concerning otoscleroma.Results:An adult woman presented with chronic suppurative otitis media with tubotympanic disease and conductive hearing loss. On mastoid exploration, dark granulations were seen, which were identified as otoscleroma on histopathological examination. The patient responded well to streptomycin.Conclusion:To the best of our knowledge, this is the first report of primary otoscleroma in the world literature. This case indicates that Frisch's bacillus can also spread to the middle ear.

AbstractObjectives:To demonstrate the need for computed tomography imaging of the temporal bone before considering revision stapes surgery in patients with recurrent or residual conductive hearing loss.Case report:We report the case of a high-riding jugular bulb with an associated jugular bulb diverticulum, which was dehiscent towards the vestibular aqueduct, in a patient with confirmed otosclerosis who did not experience hearing improvement after stapedotomy.Conclusion:This case demonstrates the usefulness of temporal bone computed tomography in the evaluation of patients with otosclerosis in whom stapedotomy has not improved hearing. In such patients, revision surgery to address residual hearing loss would eventually prove unnecessary and avoidable.

Canal Dehiscence

Dehiscence of bone overlying the superior semicircular canal can result in a syndrome of vertigo and oscillopsia induced by loud noises or by maneuvers that change middle ear or intracranial pressure. Patients with this disorder can also experience a heightened sensitivity to bone-conducted sounds in the presence of normal middle ear function. High-resolution CT scans of the temporal bones demonstrate the dehiscence. The authors describe a patient with bilateral superior canal dehiscence who had bilateral low-frequency conductive hearing loss, normal middle ear function, intact acoustic reflexes, and intact vestibular-evoked myogenic potentials. These findings would not be expected on the basis of a middle ear cause of the conductive hearing loss. A high-resolution CT scan of the temporal bones in this patient revealed bilateral superior canal dehiscence. Normal acoustic immittance findings in the presence of conductive hearing loss should alert clinicians to the possibility of inner ear cause of an air-bone gap due to superior canal dehiscence

Tomography Scan

Absence of the round window as a congenital defect is a rare entity that causes a conductive hearing loss. To the best of our knowledge, isolated and nonsyndromal round window absence has only been reported 3 times; the diagnoses were made during surgery. We are reporting on another case that was diagnosed before operation by virtual endoscopy of the middle ear during a high-resolution computed tomography scan. Although this new technique requires further validation, it may be an alternative to surgery as a means of confirming this rare diagnosis.
