AIM: The aim of the study was to improve the types of surgical intervention when performing biopsy of large-sized cystic formations of the lower jaw by cystotomy. MATERIAL AND METHODS: 44 patients were examined and surgeries were performed: 12 patients with ameloblastoma, 14 - with keratoxystone tumor, 18 - with dentigerous cyst. All patients had a retained tooth in the cyst cavity. RESULTS: For histological verification of cystic formations of large sized it is necessary to perform cystotomy-typed biopsy with bone tissue and shell fragment collection, using epithelialized flap method. CONCLUSION: Cystotomy-typed biopsy using the method of epithelialized flap can significantly reduce the rehabilitation period and allows to decide on the choice of further method of surgical treatment.
