The cause of sudden conductive loss in the absences of other vestibulo-audiologic abnormalities can be isolated to specific subsites of the ossicular chain using audiometric testing. In the absence of such abnormalities, a rare etiology may be the cause after an inciting trauma. Laryngoscope, 2024.

UNASSIGNED: The development of pneumolabyrinth without previous head trauma is a rare event; the associated symptoms may be nonspecific, and they can simulate various cochleo-vestibular pathological entities. The aim of the present study is to describe one of these rare occurrences, characterized by a peculiar onset.
UNASSIGNED: We report a case of stapes fracture secondary to ear pick penetration into the middle ear with a pneumolabyrinth that caused a recurrent paroxysmal positional vertigo (PPV) mimicking a canalolithiasis.
UNASSIGNED: The patient developed a profound left sensorineural hearing loss and an intractable PPV with \"migrant\" features. A pneumolabyrinth was visualized with high-resolution computed tomography. A perilymphatic fistula (PLF) with stapes fracture was found while performing an explorative tympanotomy. After the surgical treatment of the PLF, the patient no longer complained of vestibular symptoms.
UNASSIGNED: To our knowledge, this is the fifth case of traumatic pneumolabyrinth simulating a canalolithiasis without previous history of temporal bone trauma and/or middle ear surgery. A pneumolabyrinth should be suspected in case of patients presenting recurrent intractable PPV after ear trauma.

Isolated fracture of the handle of the malleus is a rare cause of conductive hearing loss and represents a challenge for the otolaryngologist in terms of past medical history, diagnostics, and therapy.

32 year old male presented with right facial palsy following head injury. Clinical evaluation showed hemotympanum on right with moderately severe conductive hearing loss, grade III LMN facial palsy and BPPV. HRCT of temporal bone demonstrated fracture base of skull involving the roof of mastoid with no evidence of bony injury to fallopian canal. Conservative management of head trauma resulted in satisfactory outcome except for conductive hearing loss and faciel palsy. Facial palsy was managed conservatively [physiotherapy and oral steroids] with full recovery of function after 4 weeks. Conductive hearing loss was managed by combined approach tympanaplasty. Preoperutively incudostapedial joint dislocation and fracture anterior crus of stapes were noted. Type II tympanoplasty with horizontal incus repositioning was carried out.PTA after 6 weeks showed 15-20 dB air-bone gap compared to 50-55dB air-bone gap preoperatively. BPPV recovered spontaneously. This case is reported to highlight:Importance of imaging of temporal bone.Spontaneous recovery of facial nerve function in neuropraxtc injury.Timely and appropriate surgical intervention of ossicular damage following head injury resulting in satisfatctory outcome.
