Exostoses of the External Auditory Canal
Annals of Otology, Rhinology & Laryngology, 1979Exostosis of the external ear canal is a disease unique to man. It has been identified in prehistoric man, affecting the aborigines of the North American continent. Aural exostoses are typically firm, sessile, multinodular bony masses which arise from the tympanic ring of the bony portion of the external auditory canal.

Lipomas of the Internal Auditory Canal
Archives of Otolaryngology - Head and Neck Surgery, 1978We present two cases of lipoma of the cerebellopontine angle (CPA), which brings, to our knowledge, the total reported in the literature to six. These cases had a clinical, surgical, and postoperative course that was similar to a small acoustic neuroma. The roentgenographic aspects were in keeping with small, CPA tumors.

External Auditory Canal Cholesteatoma
Archives of Otolaryngology - Head and Neck Surgery, 1997A cholesteatoma originating in the external auditory canal is a rare finding. We report 2 cases illustrating its typical localization in the inferior part of the auditory canal and its marked osteolytic character. The extension of such a cholesteatoma in the depth of the temporal bone is often larger than suggested by clinical examination.

Meningioma of the Internal Auditory Canal
Annals of Otology, Rhinology & Laryngology, 1997Meningiomas are the second most common tumor to involve the cerebellopontine angle (CPA), but controversy exists as to whether they can arise within the internal auditory canal (IAC) or whether involvement of the IAC occurs secondarily by extension from the CPA.

Exostoses of the internal auditory canal
The Journal of Laryngology & Otology, 1984An incidental post-mortem finding is reported. Its clinical relevance is discussed. It is suggested that some EAC exostoses may have a similar origin and thus an association with IAC exostoses.

Osteoma of the Internal Auditory Canal
Otolaryngology–Head and Neck Surgery, 1993The use of MRI for the evaluation of lesions in the internal auditory canal presents a potential pitfall in the diagnosis of bony lesions of the IAC, because bone is poorly visualized with this method of imaging. The presence of marrow in an osteoma might aid in its detection, since fat in the marrow has a bright signal intensity of T1-weighted imaging.

Hamartoma in the internal auditory canal
Journal of Clinical Neuroscience, 2003An 11 year old girl presented with hearing loss in her left ear and left trigeminal and facial nerve palsy. Radiological examinations revealed an enlargement of the left internal acoustic canal and the existence of a mass protruding from the canal into the cerebellopontine angle.

Lipoma of Internal Auditory Canal
Otolaryngology–Head and Neck Surgery, 1992Lipoma of the internal auditory canal is a rare tumor. Clinically, it presents like an acoustic tumor. The diagnosis can be made with the use of a magnetic resonance imaging showing a high intensity on T1‐ and low intensity on T2‐weighted image with no enhancement.

OSTEOMA OF THE EXTERNAL AUDITORY CANAL
Archives of Otolaryngology - Head and Neck Surgery, 1954NEW GROWTH of bone as the result of inflammatory and traumatic conditions is rather common; but in addition to these reparative processes, there is an occasional proliferation of bone without apparent cause or purpose. This latter condition results in the formation of a bony tumor, or osteoma, which eventually causes obstructive and pressure symptoms ...
