EXPERIENCE WITH TREATMENT OF DENTIGEROUS CYSTS OF THE JAWS IN CHILDREN

Introduction A tendency to the increasing rate of follicular jaw cysts in children has been observed in Nizhny Novgorod region lately. Material and methods. 240 children (131 (54.6%) boys and 109 (45.4%) girls) with follicular jaw cysts aged 4 to 17 inclusive were treated at the maxillofacial department of Nizhny Novgorod Regional Children’s Clinical Hospital between 2003 and 2018. The follicular jaw cyst was diagnosed based on complaints, past medical history, and X‑ray examination (orthopantomography, computed tomography) done on the outpatient basis. All patients were operated using standard methods such as cystectomy, cystotomy, cystectomy with maxillary sinusotomy (when a cyst penetrates the maxillary sinus). Results. Within the last years, duration of hospitalization was reduced from 17.0±0.6 to 4.0±0.3 calendar days (2017) and to 4.8±0.4 calendar days (2018). The amount of immature permanent teeth increased as well. Conclusions. Thus, in spite of a greater number of children with follicular jaw cysts in Nizhny Novgorod region, it was possible to reduce duration of hospitalization and increase the number of preserved immature permanent teeth due to better diagnostics, earlier cyst detection and use of cystectomy.
