[THE CRANIOMETRIC PARAMETERS AND MORPHOLOGICAL FEATURES OF THE MAXILLA IN THE HUMAN].

The aim of the research was to the study morphological features of the maxilla in people of different ages according to the results of craniometric researches. A craniometric study was performed on 50 bone preparations of the skull with the calculation of the main indices of the skull, including cranial, facial, high-longitudinal, high-latitude, transverse-zygomatic and frontal-zygomatic indices, as well as the main linear parameters of the maxilla - length, width and height. In the studied material, three main morphological types of the structure of the skull are presented: brachycrania (people with round head), mesocrania (people with middle head) and dolichocrania (people with long head).

[; THE RESULTS OF APPLICATION OF THE ADVANCED SUPRAGIOID AND SUPRAOMOGIOID NECK DISSECTION IN THE TREATMENT OF REGIONAL METASTASES OF MAXILLOFACIAL AREA CANCER].

The goal of research is to optimize the results of surgical treatment of the regional metastases of the maxillofacial area cancer by improving the technique of supragioid and supraomogioid neck dissection with its variants and substantiate the possibility of their application to the patients with malignant tumors of the maxillofacial area. 104 patients aged 7 to 86 years with malignant tumors of the maxillofacial area were examined, including cancer of the lower lip, oral mucosa, and salivary glands. The patients revealed 187 enlarged regional lymph nodes, which were removed in the course of surgery using advanced methods of supragioid and supraomogioid neck dissection.

[Methodological approaches to study characteristics of surgical anatomy of episublingual area and carotid triangle securing neck dissection within fascial sheaths].

The studies performed in 91 non-fixed human cadavers included: layer-by-layer preparation of the tissues to the depth of the bottom of operation wound after cervical lymphadenectomy within the whole anterior triangle of the neck; layer-by-layer preparation within the limits of anatomical zones and structures of the anterior triangle of the neck; study of the number and completeness of fascial sheaths in the same locations using the developed method. The anatomical findings obtained necessitate re-consideration of the conventionally described submandibular triangle medial and lateral borders in favor of their expansion. The study has defined the fascial plate dividing the contents of submandibular and carotid triangles and has specified the lines of tissue dissection with the purpose to improve the ablasticity of neck dissection operations for metastases of maxillofacial malignant tumors.

[Regional metastasizing of maxillofacial region malignant tumors according to the findings of in-unit-form removed tissues study following cervical lymphadenectomy operations].

Changes in regional lymphatic nodes according to N-sign and results of histologic study of these lymphatic nodes in unitized removed tissues following 264 performed operations of cervical lymphadenectomy were studies depending on location and occurrence of primary maxillofacial tumours.
