Abstract

The purpose of our study was to investigate the characteristics of sequestration, to determine the indications for sequestrectomy and the specificity of this surgical intervention in patients with osteonecrosis of the jaw bones, the results of surgical treatment were also evaluated. A retrospective study of 45 patients with osteonecrosis of the jaws aged from 20 to 47 years, observed in the dental clinic of PSMU from 2012 to 2019, including 29 men and 16 women, was conducted. Of these, 19 patients had osteonecrosis of the lower jaw and 8 suffered from osteonecrosis of the upper jaw. They were operated on and sparing sequestrectomy was performed. The early postoperative period was characterized by satisfactory healing: there was no purulent exudation, wound healing was accompanied by the formation of pink granulations in the area of the defect. After the surgery patients almost did not complain of pain and discomfort. Subsequently (averagely 10 days later), marginal epithelialization of the defect was noted. Functional disorders (restriction of mouth opening, dysfunction of swallowing, speech and eating) were not identified. The state of postoperative defects was assessed 3 and 6 months later. Relapse of the disease is not marked. The subjects were sent to an orthopedic dentist to manufacture complex dental-maxillary prosthesis in order to replace the resulting jaw defect and subsequent rehabilitation. The obtained favourable results after sparing sequestrectomy allow to introduce this technique into the list of standard treatment modalities for this group of patients and recommend it as the method of choice for the surgical treatment of osteonecrosis upon condition of complete sequestration.
