Snoring-Induced Nerve Lesions in the Upper Airway
Journal Title: Sultan Qaboos University Medical Journal - Year 2012, Vol 12, Issue 2
Abstract
Te prevalence of habitual snoring is extremely high in the general population, and is reported to be roughly 40% in men and 20% in women. Te low-frequency vibrations of snoring may cause physical trauma and, more specifcally, peripheral nerve injuries, just as jobs which require workers to use vibrating tools over the course of many years result in local nerve lesions in the hands. Histopathological analysis of upper airway (UA) muscles have shown strong evidence of a varying severity of neurological lesions in groups of snoring patients. Neurophysiological assessment shows evidence of active and chronic denervation and re-innervation in the palatopharyngeal muscles of obstructive sleep apnoea (OSA) patients. Neurogenic lesions of UA muscles induced by vibration trauma impair the reflex dilation abilities of the UA, leading to an increase in the possibility of UA collapse. Te neurological factors which are partly responsible for the progressive nature of OSAS warrant the necessity of early assessment in habitual snorers.

Culture Negative Confoscan Positive Acanthamoeba Keratitis A relentless course
Acanthamoeba keratitis is a protozoal infection of the eye, mainly due to the use of non-sterile solutions, like saline for disinfecting contact lenses. We report a case where delay in the diagnosis of acanthamoeba kera...
Diagnostic Screening Workflow for Mutations in the BRCA1 and BRCA2 Genes
Objectives: Screening for mutations in large genes is challenging in a molecular diagnostic environment. Sanger-based DNA sequencing methods are largely used; however, massively parallel sequencing (MPS) can accommodat...
