This is a report of three cases of mixed hearing loss that resulted from inner ear disorders. Two cases were unilateral and the third was bilateral. The diagnosis was based on the findings of normal middle and external ears in association with the absence of round window reflexes. The contralateral stapedial reflex was present in the two unilateral cases. This is the first documentation of conductive deafness due to inner ear abnormality. This diagnosis should be considered in cases of conductive hearing loss if the middle and external ears are normal. More studies are needed to establish the pathophysiology of this entity.

<p class="abstract"><strong>Background:</strong> Chronic squamosal otitis media can occur due to many conditions affecting the middle ear. Most common sign of developing a chronic squamosal otitis media is formation of a retraction pocket in the tympanic membrane leading to further development of a cholesteatoma and if not treated properly, may lead to development of dangerous complication in the affected ear. These etiological factors may also affect the other ear. It is therefore very necessary to assess and diagnose the contralateral ear, so that the disease can be intervened and treated at the right time, to prevent any deterioration in hearing of the contralateral ear.</p><p class="abstract"><strong>Methods:</strong> The prospective study was done in 100 patients with unilateral chronic squamosal otitis media, where the contra lateral ear was examined and assessed for any hearing loss.  </p><p class="abstract"><strong>Results:</strong> We found hearing loss in the contra lateral ear ranging from mild conductive hearing loss to sensorineural hearing loss with the maximum patients with mild conductive hearing loss (42%) and lowest in sensorineural hearing loss (1%).  </p><p class="abstract"><strong>Conclusions:</strong> In our study, 76 patients were seen with conductive hearing loss. Out of that, 42% patients were seen with mild conductive hearing loss, 30% with moderate conductive hearing loss and 4% with severe conductive hearing loss. 20% patients were seen with normal hearing. 3% patients were seen with mixed hearing loss and only 1% patient was seen with sensorineural hearing loss in contralateral ear.</p>

Conductive Hearing

Otic capsule dehiscences create a pathological third window in the inner ear that results in a dissipation of the acoustic energy consequent to the lowered impedance. Superior semicircular canal dehiscence (SSCD) was identified by Minor et al in 1998 as a syndrome leading to vertigo and inner ear conductive hearing loss. The authors also reported the relation between the dehiscence and pressure- or sound-induced vertigo (Tullio’s phenomenon). Prevalence rates of SSCD in anatomical studies range from 0.4% to 0.7% with a majority of patients being asymptomatic. The observed association with other temporal bone dehiscences, as well as the propensity toward a bilateral or contralateral “near dehiscence,” raises the question of whether a specific local bone demineralization or systemic mechanisms could be considered. The present report regard a case of a patient with a previous episode of meningitis, with a concomitant bilateral SSCD and tegmen tympani dehiscence from the side of meningitis. The patient was affected by dizziness, left moderate conductive hearing loss, and pressure/sound-induced vertigo. Because of disabling vestibular symptoms, the patient underwent surgical treatment. A middle cranial fossa approach allowed to reach both dehiscences on the symptomatic side, where bone wax and fascia were used for repair. At 6 months from the procedure, hearing was preserved, and the vestibular symptoms disappeared.

We report a 6-year-old girl with progressive bilateral conductive hearing loss for 2 years. She passed the newborn hearing screening conducted with otoacoustic emissions testing and had a normal development of speech and language, which indicated that her deafness was delayed-onset. She also had congenital proximal interphalangeal joints. Proximal symphalangism was confirmed by genetic testing ( NOG gene: c.406C > T, p.R136C). Bilateral stapes ankyloses were proved by surgery and her hearing was improved after stapedotomy by over 30 dB. Besides, this case should remind clinicians to carefully distinguish NOG gene-related deafness from congenital ossicular malformation and pediatric otosclerosis.

While pulsatile tinnitus (PT) and dural arteriovenous fistula (DAVF) are not rarely associated, the finding of a conductive hearing loss (CHL) in this clinical picture is unusual. Starting from a case of CHL and PT, diagnosed to be due to a DAVF, we analyzed relationship between intracranial vascular abnormalities and inner ear fluids. DAVF was treated with endovascular embolization. Following this, there was a dramatic recovery of PT and of CHL, confirming their cause-effect link with DAVF. We critically evaluated the papers reporting this association. This is the first case of CHL associated with PT and DAVF. We describe the most significant experiences and theories reported in literature, with a personal analysis about the possible relationship between vascular intracranial system and labyrinthine fluids. In conclusion, we believe that this association may be a challenge for otolaryngologists. So we suggest to consider the possibility of a DAVF or other AVMs when PT is associated with CHL, without alterations of tympanic membrane and middle ear tests.

AbstractIn ears with minor conductive hearing loss of traumatic origin, it is sometimes possible to invert the deflection of the stapedial reflex by application of a small underpressure in the external auditory meatus of the injured ear (probe ear). This inversion can be explained by an ossicular discontinuity bridge by soft tissue.

The recent application of arthroscopic surgical techniques to the temporomandibular joint (TMJ) has facilitated the diagnosis and treatment of TMJ disorders. However, as TMJ arthroscopy is performed more frequently, new complications are being recognized. We report three patients who developed severe otologic complications following TMJ arthroscopy. Two sustained complete or severe sensorineural hearing loss and severe vertigo from trauma to the ipsilateral ear. The third patient had complete facial paralysis from trauma to the facial nerve in the middle ear and a conductive hearing loss from incus dislocation. Complete hearing loss and facial paralysis from trauma to the main trunk of the facial nerve have not been reported previously as complications of TMJ arthroscopy.
