Cavernous hemangioma, also known as cavernous angioma, accounts for 10-20% of vascular malformations.1,2 Extra-axial lesions are rare. Most tumors are found in the sinuses, Meckel’s cavity, posterior fossa, including the cerebellarpontine angle and internal auditory meatus.3 This paper reports the clinical case of a patient with cavernous hemangioma involving the internal auditory meatus whose ...

Respiratory epithelial adenomatoid hamartoma (REAH) is an uncommon lesion of the upper aerodigestive tract. It is characterized by abnormal glandular formations with ciliated epithelium arising from the nasal cavity, paranasal sinuses and nasopharynx, but other locations have also been described. We did not find any other cases of this hamartomas in the external auditory canal in the literature...

OBJECTIVE To evaluate the result of the surgical treatment of vestibular schwannoma (VS) operated in dorsal decubitus (mastoid position). METHOD 240 patients with a VS underwent a retrosigmoid craniotomy for tumor resection in dorsal decubitus (mastoid position). The function of 7th and 8th cranial nerves was monitored during surgery and the opened internal auditory canal (IAC) was reconstruc...

Purpose Intracranial teratomas in children involving lateral structures such as the petrous portion of the temporal bone are very uncommon. The authors report a case of a petrous teratoma with significant extension into the cerebellopontine angle with brainstem compression. Case Report An 11-year-old girl presented left-sided facial weakness. Computed tomography (CT) demonstrated a multiloculat...

Tumors originating from ceruminous glands are rare lesions of the external auditory canal. The lack of specific clinical and radiological signs makes their diagnosis challenging. We report the case of an exceptionally rare benign tumor, a syringocystadenoma papilliferum (SCAP), in an atypical location in the bony segment of the external auditory canal with uncommon clinical signs. The special t...

A rare case of bilateral mandibular condylar fractures associated with bilateral external auditory canal fractures and otorrhagia is reported. The more severe external auditory canal fracture was present on the side of high condylar fracture, and the less severe external auditory canal fracture was ipsilateral to the condylar neck fracture. A mechanism of injury is proposed to account for such ...

Background: The tumor size is one of the main factors in treatment cerebellopontine angle (CPA) tumors, and magnetic resonance imaging (MRI) with gadolinium-based contrast agent (GBCA) provides best evaluation. However, administration gadolinium time consuming increasing cost. There a risk nephrogenic systemic fibrosis patients renal failure liver or transplantation. Objective: purpose this stu...

The aim of this paper is to describe and evaluate the feasibility of an expanded endoscopic transcanal transpromotorial approach (ExpTTA) to the internal auditory canal and the cerebellopontine angle. To this end, we performed a cadaveric dissection study in September 2015. In total, 2 heads (4 sides) were dissected focusing on anatomical landmarks and surgical feasibility. Data from dissection...

BACKGROUND AND PURPOSE Middle ear surgery is often performed through the external auditory canal, and the CT appearance of the external auditory canal after transcanal middle ear surgery can mimic erosive pathology such as carcinoma, external auditory canal cholesteatoma, or necrotizing external otitis. We reviewed the CT findings in a group of patients following transcanal surgery to highlight...
