Introduction: Malignant tumors of the parotid gland account scarcely for 5% of all head and neck tumors. Most of these neoplasms have a high tendency for recurrence, local infiltration, perineural extension, and metastasis. Although uncommon, these malignant tumors require complex surgical treatment sometimes involving a total parotidectomy including a complete facial nerve resection. Severe fu...

Introduction: Metastatic tumors of the temporal bone are extremely rare. Collet-Sicard syndrome is an uncommon condition characterized by unilateral palsy of the lower four cranial nerves. The clinical features of temporal bone metastasis are nonspecific and mimic infections such as chronic otitis media and mastoiditis.   Case Report: This report describes a rare case of metastatic adenocarcino...

. to investigate the effect of anisometropic and strabismic amblyopia on the nerve fiber layer thickness. this cross-sectional study was done on 54 amblyopic subjects, equally in both strabismic and anisometropic groups. the thickness otonerve fiber layer measured in superior, inferior, nasal, temporal quadrants and as a whole in both eyes of both groups. the means of thickness were compared in...

IMPORTANCE Minimizing morbidity when performing free flap reconstruction of the head and neck is important in the overall reconstructive paradigm. OBJECTIVE To examine the indications and success rates of free tissue transfer using small-caliber facial recipient vessels and minimal access incisions. DESIGN, SETTING, AND PARTICIPANTS Retrospective medical record review of patients with head ...

We performed sympathetic nerve reconstruction using intercostal nerve in patients with severe compensatory hyperhidrosis after sympathetic surgery for primary hyperhidrosis, and analyzed the surgical results. From February 2004 to August 2007, sympathetic nerve reconstruction using intercostal nerve was performed in 19 patients. The subjected patients presented severe compensatory hyperhidrosis...

conclusions ipbsn injury is a common complication following arthroscopically-assisted aclr and, ifn not significant, oblique direction of the incision is associated with decreasedn incidence of the injury. ipbsn injury has no effect on the function but because of then disturbance with patients' satisfaction, authors believe the oblique incision isn preferable to avoid the nerve injury during me...

The author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. The studies were performed on 200 specimens of human temporal bone. It was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), an...

  In this paper, we review novel techniques in the emerging field of spatiotemporal 4D PET imaging. We will discuss existing limitations in conventional dynamic PET imaging which involves independent reconstruction of dynamic PET datasets. Various approaches that seek to attempt some or all of these limitations are reviewed in this work, including techniques that util...
