Results of the study of electroexcitability of the skin in the area of innervation of the lower alveolar nerve

In patients with mandibular fractures, 87.6% of cases showed varying severity damage to the lower alveolar nerve (LAN). So, in most cases, when the displacement of fragments is less than 0.5 cm, a mild degree was noted, when the displacement is from 0.5-1.0 cm - an average degree, and more than 1.0 cm-a severe degree of damage to the LAN. In 3.7% of cases, violations of deep sensitivity were detected. It was revealed that the highest rates of electrical excitability of the skin were noted in 2-the 2nd and 3-3rd zones. So, at admission, the average values in patients with mild severity of damage were noted at the level of 56.5±1.5 mkA, with an average degree - of 115.8±3.1 mkA, with severe-163.8±4.5 mkA. It is noted that the higher the indicators, the more pronounced the violation of sensitivity. The values of indicators in the main group by day 32-40 were 1.6 times less than in the control group.
