Endoscopic Decompression of the Labyrinthine Segment of the Facial Nerve

Otology & Neurotology, 2020
Objective: To describe the outcome and feasibility of an exclusive endoscopic transcanal transpromontorial approach (ETTA) for decompression of the labyrinthine segment of the facial nerve (LSFN). Patient: A 60-year-old man with a left-sided transverse fracture of temporal bone ...

Influence of Distal Nerve Segment Volume on Nerve Regeneration in Silicone Tubes

Experimental Neurology, 1997
The influence of a volume of a distal nerve segment upon nerve regeneration in an 8-mm gap created within a silicone tube was examined. The rats were randomly divided into four groups. Each group had 5 mm, 1 mm, or a half volume of 1-mm nerve segment (a nerve piece of 1 mm transected longitudinally) inserted into the distal end of a silicone tube of 11

Axon repulsion during peripheral nerve segmentation

Development, 1991
Abstract The guidance of axons during embryonic development is likely to involve both adhesive and repulsive interactions between growth cones and their environment. We are characterising the role and mechanism of repulsion during the segmental outgrowth of motor and sensory axons in the somite mesoderm of chick embryos.

Superior segmental optic nerve hypoplasia in youth

Japanese Journal of Ophthalmology, 2008
The clinical characteristics of superior segmental optic nerve hypoplasia (SSOH) in youth were investigated to help establish diagnostic criteria.Eleven eyes of seven young patients (male/female ratio, 3/4; age, 15.1 +/- 3.4 years) who had good visual acuity and inferior visual field defects (VFDs) were evaluated.

Blood Flow of Segmentally Divided and Folded Nerve

Journal of Reconstructive Microsurgery, 1993
The integrity of the blood supply to three equal segments of a nerve was determined, after the nerve was cut and folded but with its epineurial vasculature remaining intact. A 7.5-cm length of the rabbit sciatic nerve was elevated on a single pedicle.

Impulses in the Segmental Nerves of the Earthworm

Journal of Experimental Biology, 1935
ABSTRACT The literature dealing with the peripheral components of the nervous system of the earthworm has been reviewed recently by Stephenson (1930) and Prosser (19346). Hence it is necessary only to mention the principal elements. The sensory endorgans are said to consist of (1) a variety of epidermal cells (“sensory cells”) which have

Segmental demyelination in Peripheral Nerves of Old Cats

Neurobiology of Aging, 1991
This study of the fine structure of sciatic nerve branches in normal old cats provides evidence indicating that segmental demyelination may account, in part, for the significant decrease with age in the mean axonal conduction velocity in these hindlimb nerves. Fibers of different diameters exhibited focal abnormalities of their myelin sheath.

Optic Nerve Head Segmentation in HRT Images

2006 International Conference on Image Processing, 2006
Accurate segmentation of the optic nerve head (or optic disk) is very useful during the analysis and assessment of glaucoma in the eye. The Heidelberg retinal tomograph (HRT) can acquire high quality images of the optic disk and also allows three dimensional topographic measurements to be made.

Surgical anatomy of the cervical segment of the hypoglossal nerve

Clinical Anatomy, 2005
The surgical anatomy of the extracranial segment of the hypoglossal nerve (HN) has been sparsely investigated in the literature. This article studies the course and anatomical and topographic relationships of the HN in 23 formalin fixed cadavers bilaterally dissected under a surgical microscope.

EFFECTS OF NERVE CONSTRICTION ON OXYGENATED EXCISED SEGMENTS OF RAT PERIPHERAL NERVE

Journal of Neuropathology and Experimental Neurology, 1973
The accumulations of axoplasmic components proximal and distal to constrictions of peripheral nerves were studied in excised, oxygenated segments of rat sciatic nerve and compared with similar phenomena occurring adjacent to in situ constrictions along the same nerve.
