background and objective: approximately 45% of benign peripheral nerve sheath tumors (pnst) occur in head and neck regions. malignant peripheral nerve sheath tumors (mpnst) are less common and only 8-15% of these tumors occur in head and neck region. in this study, we aimed at evaluating the demographic characteristics, pathologic findings, locations, main clinical presentations and family hist...

PURPOSE The translabyrinthine approach to acoustic neuroma resection offers excellent exposure for facial nerve dissection with 95% preservation of anatomic continuity. Acceptable outcome in facial asymptomatic patients is reported at 64-90%, but transient postoperative deterioration often occurs. The objective of this study was to identify preoperative clinical presentation and intraoperative ...

Nerve function assessments are crucial for surgical intervention during acoustic neuroma surgery. Cranial nerves such as acoustic and facial nerves, can be possibly damaged during tumor dissection. Proper surgical intervention should prevent neurological deficit and achieve total tumor removal. Conventionally, nerve function is qualitatively evaluated by surgeon and neurologist. Facial nerves c...

vestibular schwannoma is the most common tumor of the posterior fossa of the skull. patients referred with the primary otologic symptoms such as hearing loss, tinnitus, vertigo, imbalance, and the cranial nerve palsy. thirty-three patients were operated and treated by a team of otolaryngologist and neurosurgeon, anudiometrist, and internist. patients'chiefcomplaint was due to 94% hearing l...

The medium and long-term effects of electrophysiologic monitoring on the facial nerve function in minimally invasive surgery treating acoustic neuroma were studied. Sixty-two patients with acoustic neuroma taking minimally invasive surgeries in Dezhou Hospital from August 2014 to September 2015 were selected and randomly divided into 29 cases of the control group and 33 cases of the observation...

Contrast-enhanced MR images (at 1.5 T) were obtained in 11 patients with facial palsy. The group included five people with acute idiopathic facial (Bell's) palsy, three with chronic idiopathic facial palsy, and one each with acute facial palsy after local radiation therapy, acute facial palsy resulting from herpes zoster virus infection, and facial palsy caused by facial neuroma. Eight of the 1...

Eight patients with acoustic neuroma and five patients with hemifacial spasm, who had undergone hypoglossal-facial nerve anastomosis 1-14 years previously, were reviewed clinically and electrophysiologically with an electrically elicited blink reflex. Functional recovery from the anastomosis, as rigorously judged on a scale of good, fair and poor, was fair to poor. Electrically it was found tha...

OBJECTIVES To evaluate an interdisciplinary concept (neurosurgery/ear, nose, and throat (ENT)) of treating acoustic neuromas with extrameatal extension via the retromastoidal approach. To analyse whether monitoring both facial nerve EMG and BAEP improved the functional outcome in acoustic neuroma surgery. METHODS In a series of 508 patients consecutively operated on over a period of 7 years, ...
