The aim of this article is to determine hearing and mortality outcomes following temporal bone fractures. Retrospective chart review was performed of 152 patients diagnosed with a temporal bone fracture presenting to the emergency room at a tertiary care referral center over a 10-year period. Utilizing Patients’ previously obtained temporal bone computed tomographic scans and audiograms, fractures were classified based on several classification schemes. Correlations between fracture patterns, mortality, and hearing outcomes were analyzed using χ2 tests. Ossicular chain disruption was seen in 11.8% of patients, and otic capsule violation was seen in 5.9%; 22.7% of patients presented for audiologic follow-up. Seventeen patients with conductive hearing loss had air–bone gaps of 26 ± 7.5 dB (500 Hz), 27 ± 6.8 dB (1,000 Hz), 18 ± 6.2 dB (2,000 Hz), and 32 ± 7.7 dB (4,000 Hz). Two cases of profound sensorineural hearing loss were associated with otic capsule violation. No fracture classification scheme was predictive of hearing loss, although longitudinal fractures were statistically associated with ossicular chain disruption ( p < 0.01). Temporal bone fractures in patients older than 60 years carried a relative risk of death of 3.15 compared with those younger than 60 years. The average magnitude of conductive hearing loss resulting from temporal bone fracture ranged from 18 to 32 dB in this cohort. Classification of fracture type was not predictive of hearing loss, despite the statistical association between ossicular chain disruption and longitudinal fractures. This finding may be due to the low follow-up rates of this patient population. Physicians should make a concerted effort to ensure that audiological monitoring is executed to prevent and manage long-term hearing impairment.

Post Traumatic

Post-traumatic pneumolabyrinth is an uncommon clinical entity, particularly in the absence of temporal bone fracture. We report the case of a patient who presented to our emergency department with a headache, sudden left hearing loss and severe dizziness which began after a traumatic brain injury 3 days earlier. On examination, the patient presented signs of left vestibulopathy, left sensorineural hearing loss and positive fistula test, normal otoscopy and without focal neurological signs. The audiometry confirmed profound left sensorineural hearing loss. Cranial CT revealed a right occipital bone fracture and left frontal subdural haematoma, without signs of temporal bone fracture. Temporal bone high-resolution CT scan revealed left pneumolabyrinth affecting the vestibule and cochlea. Exploratory tympanotomy revealed perilymphatic fistula at the location of the round window. The sealing of defect was performed using lobule fat and fibrin glue. He presented complete resolution of the vestibular complaints, though the hearing thresholds remained stable.

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.

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.

The temporal bone report of an operated case of osteogenesis imperfecta tarda is presented. Histological examination confirmed the presence of bilateral fixation of the footplate by otosclerosis as the cause of the conductive hearing loss. Fragility of bony septae in the mastoid and of the stapedial crura were observed. Sensorineural impairment in later years with a reduction in neural elements in the cochlea appear related to the extent and activity of the otosclerotic foci. Additional temporal bone reports of three cases of osteogenesis imperfecta congenita show lack of deposition of the skein-like bone in the endochondral layer, sparse bony septae in marrow spaces and deficiency of the periosteal layer. The stapedial crura were thin and in two cases both were deformed and fractured.
