<p>External auditory canal (EAC) osteomas are rare, solitary benign unilateral lesion. Small lesions incidentally diagnosed and larger produce symptoms of pain, ear discharge defective hearing. Diagnosis is made based on a combination clinical history examination, radiographic imaging, histopathology. They usually confused with exostosis which multiple, bilateral, smooth-bordered, broad-b...

Meningioma of the internal auditory canal is very rare. There are only 15 previous reports of intracanalicular meningioma. The authors add a case report of a patient with meningioma of the internal auditory canal. A 31-year-old woman presented with a one-year history of headache, dizziness, hearing loss and left facial paralysis. An MRI of the temporal bone demonstrated a tiny isointense intrac...

Surgical approaches to the inner ear and internal auditory canal (IAC) are widely known and extensively recorded. The most popular can be classified as retrosigmoid, transmastoid-translabyrinthine, and middle cranial fossa approaches. For the first time, an exclusive endoscopic approach to the IAC is described here, used to remove a cochlear schwannoma involving both the IAC and labyrinth. The ...

IMAGING FINDINGS Magnetic resonance imaging (MRI) of the brain showed a 1.5to 1.8-cm solid and cystic mass that enhances on T1 with contrast at the right cerebellopontine angle and extends into the internal auditory canal, abutting the cerebellum medially (Figure 1). On the day of treatment a stereolocalization MRI showed a mass in the right cerebellopontine angle extending into the right inter...

Cutaneous neuroendocrine carcinoma (cNEC) is rarely seen in the external ear. In this paper, we newly describe a patient with cNEC in his right external auditory canal, followed by a further discussion on the clinical features, diagnosis, and treatments of cNEC of the external ear. A review of the literature showed that cNEC of the external auditory canal generally presents as asymptomatic and ...

We present the case of a 48-year-old woman with a cerebellopontine angle meningioma who presented with sensorineural hearing loss. The lesion was nearly 4 cm in maximum dimension and extended into the internal auditory canal. Hearing loss resulting from cerebellopontine angle tumor is most commonly caused by vestibular schwannomas, which arise directly from the sheath of the vestibular nerve (V...

Herniation of the temporomandibular joint (TMJ) into external auditory canal is rare as TMJ and are separated by an anterior bony wall canal. The defect can be caused trauma, otologic procedure, neoplasm, inflammation a congenital defect. Conservative treatment available if severity symptom mild or asymptomatic. However, surgical procedure considered patient experiences severe distress. There h...
