Abstract

We describe the case of a 37-year-old woman who presented with a complaint of recurrent headaches since childhood. Clinical examination revealed the presence of a reddish-bluish mass in the inferior half of the tympanic membrane in her right ear. Source and three-dimensional time-of-flight magnetic resonance angiography (MRA) detected a protruded right internal carotid artery (ICA) in the hypotympanum. The vertical segment of the ICA was absent, and the artery was narrowed and lateralized and had a “reverse 7” shape. Meanwhile, a persistent stapedial artery (PSA) was seen originating in the petrous portion of the ICA to form a middle meningeal artery. The A1 segment of the right anterior cerebral artery was hypoplastic. Based on these findings and on follow-up findings on computed tomography, the patient was diagnosed with a concomitant aberrant ICA and PSA. No intervention was undertaken. We review the management of this rare finding, and we discuss the role of MRA in its diagnosis.

Cholesterol granuloma of the external ear canal: A rare presentation

Abstract

Almost all aural cholesterol granulomas develop in the mucosa of the middle ear. We describe the case of a 14-year-old girl who presented with an asymptomatic, nontender, dark-blue, cystic lesion in the posteroinferior portion of the left ear canal. The mass was excised via a postauricular approach. Postoperatively, the mass was identified as a cholesterol granuloma on pathologic examination. To the best of our knowledge, this is the first reported case of a human cholesterol granuloma limited to the external ear canal.

Extensive external auditory canal cholesteatoma in the infratemporal area without mastoid involvement: Use of a new surgical technique

Abstract

The external auditory canal (EAC) is an unusual location for a cholesteatoma. We present the cases of 2 patients with EAC cholesteatoma who experienced extensive damage that extended from the inferior EAC wall to the infratemporal area; there was no mastoid involvement. In both cases, the cholesteatomas were removed under local anesthesia and the inferior canal wall was reconstructed with a technique that involved the placement of a pedicled musculoperiosteal flap, a cartilage graft, and a full-thickness skin graft. This simple procedure preserves a normal EAC contour, middle ear space, and mastoid cavity.

Therapeutic approaches to complicated cholesteatoma of the external auditory canal: A case of associated facial paresis

Abstract

Spontaneous cholesteatoma of the external auditory canal (EAC) is an uncommon condition that is difficult to diagnose. In a patient with such a possibility, serious clinical investigation along with radiologic and histologic exploration should be performed early on because a delay in treatment can lead to severe complications. Given the rarity of EAC cholesteatoma, no therapeutic consensus has emerged. The type of management depends on the extensiveness of invasion and bone erosion and the status of the neighboring structures. The primary therapeutic objectives are to eradicate the cholesteatoma and then to fill in the residual cavity, which in our opinion can be best accomplished with a muscle flap and EAC reconstruction. Postoperative follow-up should be carried out to look for infections, stenosis, and recurrence. We report a new case of spontaneous EAC cholesteatoma, and we review its diagnostic and therapeutic challenges.

Amyloidosis of the external auditory canal

article

Abstract

We present a case of bilateral otitis externa that did not respond to local treatment. Cutaneous biopsies revealed bilateral amyloid depositions secondary to multiple myeloma. Persistent, identical bilateral canal lesions may be the only manifestation of treatable systemic disease and should be biopsied, even though their bilaterality argues against malignancy.
