[Frequency of sensory and motor nerve injuries after maxillo-facial trauma]

ABSTRACT

One of the most common complications of trauma to maxillofacial region is nerve injuries of sensory and motor branches of the nerve V and VII in the face. The aim of this article was to study the relative prevalence of injuries of sensory part of nerve V and motor part of nerve VII. The research was descriptive analytic and information were collected by clinical observation. Samples consisted of 384 individuals refereing to Alzahra and Kashani hospitals, collected information were described by descriptive statistics methods and chi statistical test. Motor and sensory nerve involvement in maxillofacial trauma were evaluated in 384 trauma patients. The most frequent nerve damage was sensory part of the nerve V [51.3%] and the next frequent nerve damage was motor part of the nerve VII five patients [1.3%] had both of these two type of injuries. Maxillo-facial nerve injuries specially nerves V and VII were the frequent complications of maxillofacial region. Infra-orbital branch of the nerve V and buccal branch of the nerve VII were most affected. Vigilant clinical examination and early diagnosis of the nerve injuries will guide patients towards proper treatment and prevention of complications
