Superior semicircular canal dehiscence is caused by a bone defect on the roof of the superior semicircular canal. The estimated prevalence when unilateral varies between 0.4% and 0.7% and is still unknown when bilateral. Patients may present with audiologic and vestibular symptoms that may vary from asymptomatic to disabling. We report a case of a 72-year-old Caucasian woman presented to otolaryngology department reporting imbalance, bilateral pulsatile tinnitus, hypoacusis while being very sensitive to certain sounds. Physical examination was unremarkable, except for the Rinne test that was negative in both sides. The patient underwent an audiometry revealing a mild bilateral conductive hearing loss. A temporal bone CT scan was performed which evidenced bilateral superior semicircular canal dehiscence. Cervical vestibular evoked myogenic potentials and electrocochleography confirmed diagnosis. Although rare, superior semicircular canal dehiscence shall be considered in conductive hearing loss with vestibular symptoms.

Abstract Purpose of Review To review the role of imaging in otosclerosis with an emphasis on pre- and post-operative imaging evaluation. Recent Findings Pre-operative CT imaging can help define the extent of bone involvement in otosclerosis and may help avoid surgical complications due to variant anatomy or unsuspected alternative causes of conductive hearing loss. In patients with recurrent hearing loss after surgery, CT imaging can clarify prosthesis position and re-assess anatomy. Summary CT imaging complements otologic exam and audiometry findings in patients with suspected otosclerosis, for pre-operative planning, and post-operative assessment for patients with recurrent symptoms.

In Reply.— Dr Ruben raises concerns about our publication in this journal on language growth in children with expressive language delay.1 Ruben's position is that hearing loss accounts "for much of the expressive language delay seen in children at this age" and that, because we did not include that variable in our study, this "brings into question any conclusions drawn from their data." We are pleased that Ruben has raised the issue of the role of conductive hearing loss because we have gathered relevant data since the publication he questions.

Objectives: To evaluate the predictive role of the audiometric Carhart's notch for the assessment of middle-ear pathology prior to surgical intervention.Method: In this retrospective analysis, a total of 315 operated ears of 305 patients were evaluated regarding their pre-operative pure tone audiograms and peri-operative findings. The probable relationship between the middle-ear pathologies found and the Carhart's notch found on pre-operative pure tone audiometry was investigated. Patients with conductive hearing loss who obtained at least a 10 dB improvement (at 1 and 2 kHz frequencies) in their bone conduction threshold post-operatively were included in the Carhart's notch group. The pathologies underlying Carhart's notch were compared.Results: Three hundred and fifteen ears of 305 consecutive patients with conductive hearing loss were operated on due to middle-ear pathology. In patients with otosclerosis and tympanosclerosis, a Carhart's notch was seen at 2 kHz in 28 (93 per cent) patients but at 1 kHz in only two (7 per cent). However, in patients with chronic otitis media, a Carhart's notch was seen at 1 kHz in 10 (55 per cent) patients and at 2 kHz in eight (45 per cent) patients.Conclusions: Otitis media with effusion, tympanosclerosis and congenital malformations should be considered in the differential diagnosis of a patient with a Carhart's notch seen on pure tone audiometry. A Carhart's notch at 2 kHz indicates stapes footplate fixation, whereas one at 1 kHz indicates a mobile stapes footplate; the footplate mobility can thus be predicted pre-operatively.

Where the threshold-duration function has been shown to be systematically affected by sensorineural hearing losses of cochlear origin, preliminary studies have strongly suggested the contrasting finding that conductive hearing losses have no effect. Two series of experiments were performed to examine more fully these separate effects. Threshold-duration functions were obtained from listeners presenting 1) pure conductive and 2) mixed hearing impairments. The results indicate that the threshold-duration function is indeed differentially affected. More exactly, only the sensorineural component of a hearing loss affects the results which are obtained; while the conductive component has no effect. Such findings are interpreted to indicate that the threshold-duration function provides additional information not presently available for the differential diagnosis of auditory disorders.

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.

Objective To evaluate the effects of conductive hearing loss and occlusion on bone-conducted cervical vestibular evoked myogenic potentials (cVEMPs). Study Design Prospective cohort study conducted in the year 2018. The right ear of each volunteer was evaluated under 3 conditions by using bone-conducted cVEMPs: normal (open external auditory canal), occluded (conductive hearing loss with occlusion effect), and closed (conductive hearing loss without the occlusion effect). Setting Single academic center. Subjects and Methods The study comprised 30 healthy volunteers aged 20 to 35 years (16 women, 14 men). All had normal hearing and no vestibular or auditory pathologies. The thresholds and amplitudes of cVEMP responses were recorded for the 3 conditions. The results of each condition for a particular participant were compared. Results As compared with the open condition, the conductive condition increased thresholds by 2.8 dB ( P = .01), and the occluded condition decreased thresholds by 3.8 dB ( P = .008). The amplitude in the occluded condition was larger than the normal condition and the conductive condition (mean difference: 20.64 [ P = .009] and 31.76 [ P < .001], respectively) Conclusion The occlusion effect is present in cVEMP responses. The mechanism is not due to the conductive hearing loss induced. Clinical implications include potentially altering vestibular function with sealed hearing aids and in the surgically modified ears (ie, obliterated ears and open cavity mastoidectomy).
