Tympanum

Tympanic membrane perforation with squamous epithelial ingrowth

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

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.

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.

Eosinophilic otitis media is refractory to conventional therapy for otitis media and may lead to severe hearing impairment if not recognized promptly.

Tympanostomy tubes can cause a foreign-body reaction that can lead to myringitis and the development of granulation tissue and polyps.

Abstract

We describe an unusual case of breast cancer metastatic to the middle ear in a 71-year-old woman. The metastasis was the initial sign of disseminated disease 20 years after the patient had undergone a quadrantectomy for her primary disease. Computed tomography (CT) demonstrated the presence of an intratympanic mass with a soft-tissue density that was suggestive of chronic inflammation. The patient underwent a canal-wall-down tympanoplasty. When a brownish mass was found around the ossicles, a mastoidectomy with posterior tympanotomy was carried out. However, exposure of the tumor was insufficient, and therefore the posterior wall of the ear canal had to be removed en bloc. Some tumor was left on the round window membrane so that we would not leave the patient with a total hearing loss. Our case highlights the limitations of CT and magnetic resonance imaging in differentiating inflammatory and neoplastic lesions.

Extrusion of ossicular prostheses results from postoperative tympanic membrane medialization. The incorporation of cartilage grafting material is recommended to minimize extrusion.

For the treatment of a small glomus tympanicum, surgical excision via an anterior tympanotomy approach is possible.

Juvenile xanthogranuloma of the tympanic membrane: A case report

Abstract

Juvenile xanthogranuloma (JXG) is a benign, non-Langerhans cell histiocytic lesion that generally affects infants and children. These lesions characteristically appear as a solitary, yellow, cutaneous nodule of the head, neck, or trunk. Subcutaneous and extracutaneous forms can involve the gastrointestinal tract, kidney, lung, gonads, pericardium, central nervous system, temporal bone, larynx, and eye. We describe the clinical presentation, imaging, histochemical findings, and management of a solitary JXG of the tympanic membrane in a 17-month-old girl. The patient underwent surgical resection and was without disease several months following surgery and reconstruction of the defect. To the best of our knowledge, this is the first reported case of a JXG of the tympanic membrane.

Bilateral hemotympanum secondary to septoplasty

September 7, 2012     Jae Hoon Lee, MD
article

Hemotympanum can be caused by temporal bone fractures, barotrauma, administration of anticoagulants, hematologic disorders, and chronic otitis media secondary to the formation of granulation tissue or a cholesterol granuloma. It can also occur secondary to nasal packing or spontaneous epistaxis, as well as eustachian tube dysfunction.

Mycoplasma an unlikely cause of bullous myringitis

June 4, 2012     Lisa Cramer, BA; Dina M. Emara, MBBCh; Arun K. Gadre, MD, FACS
article

Despite common belief, Mycoplasma pneumoniae is an extremely rare causative agent for bullous myringitis. Instead, it is caused by the same organisms responsible for acute otitis media.

Primary acquired cholesteatoma

April 30, 2012     Joseph A. Ursick, MD; Jose N. Fayad, MD
article

Cholesteatomas are believed to form as the result of poor eustachian tube function with resultant tympanic membrane retraction and a lack of normal epithelial migration.
