Tympanic membrane perforation with squamous epithelial ingrowth

August 27, 2014     Danielle M. Blake, BA; Alejandro Vazquez, MD; Senja Tomovic, MD; Robert W. Jyung, MD

The squamous epithelium of the tympanic membrane and external auditory canal exhibits an inherent migration pattern to facilitate the exfoliation of keratinizing squamous cells as part of a natural cleansing mechanism.

Laterality of sudden sensorineural hearing loss

August 27, 2014     Michael Reiss, MD; Gilfe Reiss, MD
article

Abstract

It is known that sudden sensorineural hearing loss and other otoneurologic diseases, such as tinnitus or Ménière disease, occur more frequently in the left ear than in the right. We studied lateralization of sudden deafness in 489 patients treated at Radebeul Hospital from January 2004 to December 2009. The male-to-female ratio was 1:1.24; we found a predominance of the left side only in female patients. The cause for this predominance is unclear. The slight asymmetry might indicate a greater vulnerability of the left inner ear in women, suggesting hormonal factors in the genesis of sudden deafness.

Pediatric sensorineural hearing loss

Children with hearing loss should avoid noise exposure, and families should be counseled to protect their child's hearing environment and to educate their children about the long-term need to avoid excessive noise exposure.

Tympanic paraganglioma

article

Patients classically present with pulsatile tinnitus and a red mass medial to the tympanic membrane. Some patients may have findings of a red mass that blanches with pneumatic otoscopy, called Brown's sign.

Unilateral sensorineural hearing loss and facial nerve paralysis associated with low-voltage electrical shock

February 12, 2014     Mahmut Ozkiris;, MD
article

Abstract

Electrical injuries can occur as a result of contact with low- or high-voltage electricity. Low-voltage injuries are more common, as they usually occur in the home, but reports in the literature are few. After exposure to electric current, almost every organ system in the body is affected. The severity of an injury depends on many factors, including the type of current, the duration of exposure, and the resistance of the tissue involved. Reported cases of hearing loss and facial nerve paralysis associated with low-voltage electrical shock are rare, and minimal information is available about this circumstance. In this article, the author describes a case of low-voltage electrical shock in a 20-year-old man. To the best of the author's knowledge, this is the first report in the literature of a resolution of unilateral sensorineural hearing loss and facial nerve paralysis caused by a low-voltage electrical shock.

Delayed recovery of speech discrimination after fractionated stereotactic radiotherapy for vestibular schwannoma in neurofibromatosis 2

article

Abstract

Hearing loss commonly occurs after radiation therapy for an acoustic neuroma, and it is highly unusual for hearing to return after a prolonged period of time. We report the case of a 12-year-old boy with neurofibromatosis 2 who underwent fractionated stereotactic radiotherapy for the treatment of a left-sided vestibular schwannoma. Following treatment, he demonstrated an elevation of pure-tone audiometric thresholds and a sudden decrease in speech discrimination score (SDS) to 0%. However, 20 months postoperatively, his SDS suddenly and spontaneously rose to 92%, although there was no improvement in his speech reception threshold. We discuss the possible reasons for the unusual outcome in this patient.

Temporal bone fracture

Transverse fractures account for approximately 20% of temporal bone fractures. They occur secondary to frontal or occipital head trauma, and they run perpendicular to the petrous pyramid.

Vertebral artery dissection: An unusual cause of transient ataxia, vertigo, and sensorineural hearing loss

December 20, 2013     Leila L. Touil, MBChB; Glen James Watson, FRCS, DOHNS; Michael Small, FRCS
article

Abstract

We present the case of a 33-year-old man who was admitted with intermittent ataxia, vertigo, and sensorineural hearing loss as a result of a vertebral artery dissection following minor neck trauma. Our aim is to highlight the importance of obtaining magnetic resonance imaging, magnetic resonance angiography, and/or duplex color-flow imaging when presented with a case of fluctuating vertigo and sensorineural hearing loss with side-specific ataxia. Likewise, it is important to obtain the input of neurologists to optimize a patient's prognosis and minimize long-term sequelae.

Bilateral middle cranial fossa encephaloceles presenting as conductive hearing loss

December 20, 2013     Colleen T. Plein, MD; Alexander J. Langerman, MD; Miriam I. Redleaf, MD
article

Abstract

We report a case involving a patient with bilateral middle cranial fossa encephaloceles extending into the middle ear and causing conductive hearing loss. An obese, 47-year-old woman with a history of a seizure disorder presented with a slow-onset subjective hearing loss. Examination revealed opaque tympanic membranes, and audiometry showed a mixed hearing loss bilaterally. Myringotomy demonstrated soft tissue behind each tympanic membrane. Biopsy, computed tomography, magnetic resonance imaging, and mastoidectomy confirmed the diagnosis of bilateral middle cranial fossa encephaloceles. Bilateral encephaloceles are uncommon, and the resulting bilateral conductive hearing loss secondary to mechanical obstruction of ossicular vibration is even more rare. This patient's obesity and seizures perhaps contributed to her disease process.

Extrusion of hydroxyapatite prostheses is unfortunately a common complication of middle ear surgery.
