OBJECTIVES To establish a sound objective model for assessing the effects of neurotrophic factors on facial nerve function after injury and to compare the effects of brain-derived neurotrophic factor (BDNF) with its neutralizing antibody on facial nerve function after injury. DESIGN Prospective electrophysiologic analysis of recovery of function 4 weeks after axotomy involving facial nerve tr...

OBJECTIVE To describe denervation features of facial musculature following facial nerve injury in a rodent model. METHODS Six Wistar-Hannover rats underwent unilateral transection and immediate repair of the facial nerve. After 8 weeks, muscular bundles consisting of dilator naris and levator labii superioris from both sides were analyzed for mean muscle cell diameter and the percentage of mu...

The nasal bones are the most commonly fractured segment of the facial skeleton; over 50% of fractures from blunt maxillofacial trauma are sustained in this area (1,2). The prominent position and the relatively poor resistance offered by the osseocartilaginous framework predispose the nasal pyramid and underlying septum to varying degrees of comminution and displacement. The injury that results ...

A retrospective analysis was undertaken of 108 patients with facial injuries from falling who presented at the Plastic Surgery Unit of the Toyo-oka Public Hospital from 1988 to 1990. Facial injuries from falling were common in little children, in those < 6 years of age comprising 45.4% of injuries. Age-dependent characteristic injury sites were found (i.e., in those < 2 years old, the forehead;...

COMPLEX, OPEN MAXILLOFACIAL FRACTURES ARE OFTEN ACCOMPANIED BY EXTENSIVE CONTAMINATION, CRUSH, OR AVULSION OF THE OVERLYING SOFT TISSUE, THERE HAVE BEEN TWO ALTERNATIVES TO TREATMENT: either radical debridement of all contaminated tissue, fixation of the underlying fractures, and soft tissue closure by pedicle flap or graft is done; or more conservative debridement is repeated multiple times un...

Fireworks are used to celebrate a variety of religious, patriotic, and cultural holidays and events around the world. Fireworks are common in the United States, with the most popular holiday for their use being national Independence Day, also known as July Fourth. The use of fireworks within the context of celebrations and holidays presents the ideal environment for accidents that lead to sever...

We sought to determine whether electrical stimulation (ES) with subthreshold, continuous, low-frequency impulses is a viable clinical method for improving functional recovery after facial nerve crush injury. In 10 rabbits, bilateral crush injuries were made on the facial nerve by compression for 30 s with mosquito forceps, causing complete facial paralysis. Subthreshold continuous direct curren...

Facial gunshot injuries are unusual and complicated clinical entities. Because of the mechanism of injury, early aggressive primary reconstruction might not be ideal. Initial conservative management followed by staged secondary reconstruction could be performed to obtain satisfactory functional and aesthetic results. Reconstruction of the cranio-maxillo-facial deformities requires a multi-disci...

introduction: we present a retrospective two-center study series and discussion of the current literature to assess the benefits of facial nerve monitoring during parotidectomy. materials and methods: from 2007 to 2012, 128 parotidectomies were performed in 125 patients. of these, 47 procedures were performed without facial nerve monitoring (group 1) and 81 with facial nerve monitoring (group 2...

The present study evaluated the thermodynamic characteristics of a prototype respiratory heat and moisture exchanger (HMS), particularly its ability to prevent cold injury to the face. The HME comprised a thermally insulated oro-nasal mask with a cylindrical heat and moisture exchanger protruding from the centre of the mask. The heat exchanging unit contained an aluminium “honeycomb” structure ...
