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.

[Experience in treatment of patients with spacious cysts of jaws].

Experience in operative treatment of 91 patients with spacious cysts of jaws occupying from 1/3 to capital DSE, Macedonian and more of the lower jaw volume was presented. In 36 patients keratocysts were found and in 55 patients teeth containing cysts. In the latter case it is obligatory to remove fully the cyst capsule because its epithelium is capable of metaplasia and neoplastic transformation. Patients were treated with the use of 2 stage method. 1st stage included decompression operation of cystotomy type; 2nd stage was performed 1-2 or more years later (depending upon primary cyst size) and consisted of remaining cyst capsule removal with wound closure. Benefits of 2 stage operation were described.

Analysis of case histories of patients with odontogenic sinusitis helped single out the typical errors often made by the practitioners when diagnosing and treating this disease. These errors are: untimely diagnosis of the perforation, inadequate examination, erroneous interpretation of the diagnosis. When the maxillary sinus bottom is perforated during removal of a tooth, the physician often erroneously closes this opening. Treatment of sinusitis is often carried out regardless of the disease form and stage.
