[Assessment of microhaemodynamics and oxygenation in tissues after the vestibuloplasty with the use of a free dermal autograft in patients after the reconstructive jaw surgery with the use of the revascularized autografts]. / Otsenka sostoyaniya mikrogemodinamiki i oksigenatsii v tkanyakh posle vestibuloplastiki s ispol'zovaniem svobodnogo dermal'nogo autotransplantata u patsientov posle rekonstruktivnoi operatsii na chelyustyakh s primeneniem revaskulyarizirovannykh autotransplantatov.

Purpose of the study: to study the features of microhaemodynamics and oxygenation in soft tissues in the area of the plastically reconstructed jaw after the vestibuloplasty. MATERIALS AND METHODS: The study included 40 patients aged 20 to 65 (21 males and 19 females). The patients were divided into two groups: I group (14 patients) - patients after reconstructive surgery with the use a fibula autograft without the inclusion of a musculocutaneous «islet¼; II group (26 patients) - patients after reconstructive surgery with the use a fibula autograft with the inclusion of a musculocutaneous «islet¼. To correct the prosthetic bed soft tissues, all patients underwent vestibuloplasty with the use of a free dermal autograft. To study microcirculation in tissues, the laser Doppler flowmetry (LDF) method was used. Microcirculation status was assessed by microcirculation index characterizing the level of tissue blood flow; parameter «σ,¼ which determines the oscillability of the flow of red blood cells and by coefficient of variation, characterizing vasomotor activity of microvessels. According to the Wavelet analysis of LDF-grams the blood flow bypass was determined. An oxygenation study was carried out in the tissues of the plastically restored jaw by optical tissue oximetry, the results of which determined the oxygenation index and the specific oxygen consumption index. RESULTS: According to LDF data after vestibuloplasty, it was found that in I group, the microcirculation in soft tissues of the plastically reconstructed jaw restored in 21 days, and in II group in 2 months, which persisted at 6 months. In I group, the level of oxygenation and specific oxygen consumption normalized in 21 days, and in II group in 2 months, which persisted at 6 months. CONCLUSION: Based on the results of this functional study, it was found that before vestibuloplasty microcirculation and oxygenation indices in II group patients were lower than those in I group patients. After vestibuloplasty with the use of a free dermal autograft, microcirculation indices in II group patients restored in 2 months, while in I group patients those indices restored in 21 days.

[The use of modern dressings after complex treatment of malignant tumors of the maxillofacial region]. / Primenenie sovremennykh perevyazochnykh materialov posle kompleksnogo lecheniya zlokachestvennykh novoobrazovanii chelyustno-litsevoi oblasti.

The number of patients with malignant tumors of the head and neck is constantly growing. However, after a favorable outcome of complex treatment patients may experience adverse consequences. Surgeon should understand conditions of surrounding tissues that have undergone radiation therapy. It is necessary for special management because regenerative potential of postoperative wounds decreased. The search and development of effective wound dressings are aimed at reducing the risks of postoperative complications and improving the quality of life of this group of patients.

[Rational choice of revascularized autograft in midface reconstruction]. / Ratsional'nyi vybor revaskuliarizuemogo autotransplantata pri rekonstruktsii srednei zony litsa.

The article presents an analysis of the results of the use of revascularized autografts in the plastic elimination of combined defects in the middle zone of the face. Difficulties and negative moments of each of them were revealed and recommendations were given on the rationality of their clinical application with the development of the algorithm of surgical tactics.
