[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.
