Substantiation for using modified submandibular approach for incision and drainage of odontogenic infection of the mouth floor

Objective: substantiation for the use of modified submandibular approach for treating odontogenic infection of the mouth floor.

Materials and methods. 62 patients were involved in this prospective study. The main group consisted of 30 patients with mean age 46.8±11.8, 16 men (53.3%), 14 women (46.7%). Patients were treated with the modified submandibular approach with partial incision of the mandibulohyoid sac; the application for invention No. 2019118924, priority of 17.06.2019. The comparison group consisted of 32 patients with mean age 48.0±11.8, 17 men (53.1%), 15 women (46.9%). Patients were treated with the standard submandibular approach. The main group and the comparison group were comparable in age and sex (p>0.05), the background pathology and antibacterial therapy.

Results. The modified approach allows to reduce the time of postoperative surgical site purification from 5.9±1.9 days in the comparison group, in the main group up to 4.5±1.1 days (p<0.05); granulation tissue from 5.1±2.0 days in the comparison group, in the main group up to 3.7±1.0 days (p<0.05); secondary suture application from 7.0±2.2 days in the comparison group, in the main group up to 5.8±1.2 days (p<0.05). There were no differences in the average bed days (the main group – 8.2±0.9 days, the comparison group – 9.0±2.1 days, p>0.05) and the spread of the infection to adjacent organs (1 case in the main group, 3 cases in the comparison group, p>0.05).

Conclusion. The modified method of treating odontogenic infection allows reducing the time of postoperative wound purification, and facilitating the appearance of granulation tissue and application of sutures.
