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.

Blunt head trauma without any temporal bone fracture or longitudinal temporal bone fracture, with an associated fracture of the labyrinth may cause labyrinthine injury with sensor neural hearing loss and vertigo because of a concussive injury to the membranous labyrinth. Sudden sensory neural hearing loss is relatively frequent. In most cases, the etiology is not discovered. One of the possible causes for sudden deafness is inner labyrinth bleeding or concussion, which were difficult to diagnose before the advent of magnetic resonance imaging. Vertigo without a demonstrable fracture may also be the result of labyrinthine concussion, cupololithiasis and perilymphatic fistula. We describe the clinical case of a patient with acute traumatic hearing loss and vertigo, without skull base fracture detected on computed tomography. Magnetic resonance study was also performed. We have integrated the discussion with features that allow the differential diagnosis from other similar conditions.

A perilymphatic fistula (PLF) is defined as leakage of perilymph with several possible causes such as superior canal dehiscence through trauma, temporal bone fracture, or sudden pressure change (e.g., skydiving or scuba diving). Pneumolabyrinth can result from temporal bone fracture after trauma, or sudden pressure change in the middle ear or cerebrospinal fluid, such as excessive nose blowing or Valsalva maneuver. A PLF and pneumolabyrinth may occur without trauma, associated with a sudden pressure change in the middle ear. We report two cases of PLF followed by pneumolabyrinth and one case of suspicious PLF without pneumolabyrinth after excessive nose blowing. All three cases were diagnosed as having sensorineural hearing loss and the patients recovered completely after conservative treatment. We report various CT findings of pneumolabyrinth and PLF, from normal CT findings to air pockets in the labyrinth and soft tissue density around the stapes.

<p class="abstract"><strong>Background:</strong> <span lang="EN-IN">Temporal bone fractures are traditionally classified as transverse, longitudinal or mixed fractures depending on their relationship to the petrous pyramid. However recent studies show that classifying temporal bone fractures as otic capsule sparing (OCS) and otic capsule violating (OCV) types has more relevance with the prognosis of hearing loss and other associated complications. To assess the predictive value of two different types of temporal bone fracture classification systems with respect to hearing loss and its type.</span></p><p class="abstract"><strong>Methods:</strong> This prospective study was done on patients attending a tertiary care hospital in the study period of one year. Temporal bone fracture patients satisfying inclusion and exclusion criteria were clinically and audiologically evaluated. All patients with temporal bone fractures were categorized into two groups - Longitudinal/ Transverse (old) and OCS / OCV (new). <span lang="EN-IN">Hearing loss was evaluated audiologically on multiple intervals- initially following the injury once the patient is stable, later after a gap of 1 month and 3 months following the injury. </span></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">During the study period, 45 patients presenting with temporal bone fractures who satisfied the selection criteria were evaluated. The correlation was statistically significant for new classification system (<em>P</em>- 0.000) with respect to severity and prognosis of hearing loss which was not the case with the old system (<em>P</em>- 0.450). </span></p><p class="abstract"><strong>Conclusions:</strong> <span lang="EN-IN">We found that classifying temporal bone fractures into OCV and OCS correlates well with the severity of the hearing loss, the prognosis of the patient and the residual hearing disability when compared to the traditional system.</span></p>
