Brief summary
The aim of this study is to investigate the incidence of lingual nerve injury and related factors in difficult intubation cases. Demographic data of difficult intubation cases and body mass indices, thyromental and sternomental distances, mallampati classification, neck circumference, maximum mouth opening be recorded.Numbness of the tongue and metallic taste will be questioned
Detailed description
The lingual nerve is the anterior descending branch of the posterior trunk of the mandibular division of the trigeminal nerve. Lingual nerve injury is a recognised complication of orotracheal intubation and has been associated with forceful laryngoscopy. Although left-sided neuropraxia has been reported, right-sided lesions are thought to be more common because the standard Macintosh laryngoscope exerts pressure on the right side of the tongue. Lingual nerve injury following orotracheal intubation was first described in 1971 by Teichner who reported a right-sided neuropraxia which was attributed to direct pressure from the laryngoscope.
