Abstract

The trauma has been known as a major etiologic factor in temporomadibular joint disorders. The endotracheal intubation is suspected as one of the traumatic factor to temporomandibular disorder. But there are few reports about the amount of mouth opening during endotracheal intubation and temporomandibular joint disorder after endotracheal intubation. The authors studied the effects of endotracheal intubation to temporomandibular joint with 70 patients given surgical operation through general anesthesia. The results were as follows. 1. The mean amount of mouth opening for entire patients during endotracheal intubation was 26.3mm (s, d : 2.6), for oral intubation group 25.9mm(s, d : 3.2), for nasal intubation group 26.6mm(s, d : 1.9). There was no difference between two group stastically. (p<0.05) 2. 1 week later endotracheal intubation, the maximum mouth opening increased 1.5mm for entire patients, 1.5mm for oral intubation group, 1.6mm for nasal intubation group than behare endotracheal intubation. 3. Five patients complained the discomforts around temporomandibular joint after endotracheal intubation. The amount of mouth opening during endotracheal intubation was within physiologic range. It seemed that $45^{\circ}$ upward endoscopic lifting for exposure of glottis gave trauma to temporomandibular joint.
