OBJECTIVE Microsurgical and endoscopic techniques are vastly utilized in brain tumor surgery. Combining both the same procedure has different forms applications. The aim of this work was to discuss usefulness describe technical benefits endoscope-assisted microsurgery (EAMS) treating pediatric tumors various anatomical locations. METHODS medical records 106 children who had undergone EAMS for a...

Recurrent meningitis occurs usually due to immunological or anatomical abnormality as well as chronic parameningeal infections. Anatomical abnormalities can be acquired or congenital and most of them are located in the head and neck region. Congenital defects include inner ear abnormalities, patent cochlear aqueduct, patent Hyrtlʼs fissure, abnormal developed facial canal and dehiscence at the ...

BACKGROUND Osteoradionecrosis (ORN) is one of the most serious complications of radiotherapy of nasopharyngeal carcinoma (NPC). ORN rarely occurs in the external auditory canal. METHODS This is a retrospective review of 11 NPC patients who had ORN in the external auditory canal. Exposed necrotic bone over the external auditory canal was the diagnostic hallmark. Three patients wore hearing aid...

Ticks are obligate blood-sucking arthropods that exist worldwide. Their targets include all vertebrates and humans. Ticks are harmful to people with regard to transmission in many viral, bacterial, and parasitic infections. In addition to these diseases and toxin-induced neurological complications, tick-induced paralysis is a syndrome related to neurotoxin production, and its mortality ratio in...

In patients with repeated exposure to cold water, such as cold water surfers and kayakers, the reactive exostoses can occur in the external auditory canal. The external auditory canal exostoses are multiple, benign bony growths. They can cause external auditory canal stenosis, leading to repeated otitis externa and potentially conductive hearing loss. It is vital to consider this entity in susc...

Unilateral cystic inner ear anomalies were diagnosed in two siblings, a 9 year old boy and a 6 year old girl. X-ray examination of the temporal bone was performed, together with audiological examinations and vestibular function tests. The common tomographic X-ray findings consisted of an enlarged solitary sac type deformity of the vestibule with narrowing of the internal auditory canal, severe ...

Squamous cell carcinoma infrequently arises in the middle ear and external auditory canal. Mastoid complex primary carcinoma is extremely rare. The site of origin of these tumors may be obscure when large destructive lesions are encountered at the initial presentation. Imaging techniques may provide a clue as to the origin of these carcinomas. The complementary role of CT and MR is illustrated ...

OBJECTIVES/HYPOTHESIS To evaluate a transcanal approach for placement of a stimulating electrode array in the cochlear nerve. STUDY DESIGN Prospective cadaveric temporal bone study. METHODS Ten human cadaveric temporal bones were dissected. Both a facial recess approach with mastoidectomy and a transcanal approach using the novel technique were performed in each bone. A middle fossa dissect...

A 46-year-old woman had left-sided otalgia, tinnitus , hearing loss, and headaches centered on the left eye. Left peripheral facial nerve palsy occurred 2 days later, and the facial pain worsened. Brainstem auditory evoked potentials, usually abnormal in cases of acoustic neuroma, were normal. An MR study with TR = 2000, dual echo, and a 1 0-mm axial screening procedure showed only a vague asym...
