the occurrence of mast cells is studied in the normal facial nerve and in the facial nerve post mortem exam of patients with chronic suppurative otitis media without associated facial paralysis. a small number of mast cells were found in the normal facial nerve. these cells were usually located in close proximity to the endoneural and epineural blood vessels. the number of mast cells was increa...

MR imaging of peripheral nerves has been described in relation to abnormalities such as nerve injury, entrapment, and neoplasm. Neuroma formation is a known response to peripheral nerve injury, and here we correlate the MRN appearance of postinjury neuroma formation with intraoperative findings. We also present the MR imaging features of surgical treatment with a synthetic nerve tube and nerve ...

To clarify the factors contributing to patient satisfaction with facial movement after the classic hypoglossal-facial nerve anastomosis, we examined 46 such patients who consented to an interview and video-recording. No correlation was seen between the physician's evaluation of returned function (according to Yanagihara's 40-point scale and the grading system of House-Brackmann) and the scores ...

Traumatic neuroma, neurofibroma, neurilemmoma, palisaded encapsulated neuroma and malignant peripheral nerve sheath tumor (MPNST) are peripheral nerve sheath tumors and present neural origin. The goal of this study was to describe the epidemiological data of oral peripheral nerve sheath tumors in a sample of the Brazilian population. Biopsies requested from the Oral Pathology Service, School of...

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...

INTRODUCTION There have been anecdotal reports of the efficacy of diathermy (electrocoagulation) in the prevention of neuroma formation. However, this has not been investigated in the laboratory. In this experiment involving 40 rats, diathermy was applied to the terminal proximal ends of transected rat common peroneal nerves to evaluate its effect on neuroma formation. MATERIALS AND METHODS M...

AIM To explore the effect of nerve regeneration through repairing the defect of sciatic nerve in rats with the combination of optimized acellular allogeneic nerve and autologous neuroma. MATERIAL AND METHODS 30 SD rats were randomly divided into two groups A and B, with 15 in each, which were used in preparing the models of the autologous neuroma and the defect of sciatic nerve. In the group ...
