[The involvement and reparative regeneration of the mucosa of the airways in thermal inhalation trauma in burn patients]. / Porazhenie i reparativnaia regeneratsiia slizistoi obolochki vozdukhonosnykh putei pri termoingaliatsionnoi travme u obozhzhennykh.

The adaptive reorganization in mucosa of the upper airways was investigated in 15 burned patients during the first 24 days postburn using historadiography in vitro. The fibreoptic bronchoscopic biopsy specimens obtained in vivo were analysed. The initial significant destructive changes in mucosa and inhibition of DNA and RNA synthesis in the epitheliocytes were changed at day 8 postburn by the development of consecutively arising regenerative processes. The intensification levels of proliferative and metabolic reactions obtained under conditions of the serial bronchoscopies represent important diagnostic and prognostic criteria.

[Use of cutaneo-fascial flaps in reconstructive surgery of the lower extremities]. / Primenenie kozhno-fastsial'nykh loskutov v vosstanovitel'noi khirurgii nizhnikh konechnostei.

Defects in the soft tissues of the lower extremities after burns and traumas in 10 patients were managed by plastic surgery using ++cutaneo-fascial grafts formed from the leg of the same or contralateral side. The operation was performed in two or three stages. ++Cutaneo-fascial grafts formed on the posteromedial or posterolateral surface of the leg may have a width:length ratio of 1:3. In cross plastics the proximal one third of the graft is folded like a tube. Inclusion of the vena saphena magna in the graft and measures aimed at prevention of separation of the fascia from the layer of fat increase the viability of the graft. Secondary deformity is significantly reduced by modelling the edges of the donor wound and closing it with an unperforated graft of split skin.

[Surgical treatment of post-burn deformities of the neck]. / Khirurgicheskoe lechenie posleozhogovykh deformatsii shei.

Surgical treatment of 205 patients is analysed. It is shown that the traditional methods of correcting post-burn deformities fail to produce good results, either functional or cosmetic. The authors correct post-burn deformities and contractures of the neck by plasty with a graft of uninjured skin taken from the anterior surface of the chest. This method provides the possibility for improving considerably both the functional (in 80.3%) and the cosmetic (in 74.2% of cases) results of restorative-reconstructive operations. It is concluded that this method for correction of post-burn contractures of the neck is the operation of choice.

[Treatment of postburn cicatricial deformations and contractures of the neck]. / Lechenie posleozhogovykh rubtsovykh deformatsii i kontraktur shei.

Postburn cicatrices and contractures of the neck have been corrected in 130 patients by the routine methods (Z plasty, free transplantation of the skin, combined methods). Analysis of the late results has shown that contractures have been eliminated or reduced in 70% of the patients, but a good cosmetic effect has been achieved in only 30%. In 75 patients plasty of the postburn cicatricial deformations of the neck has been made with the use of dermo-fascial flaps of the intact skin of the thoracic wall. This technique developed by the authors has completely removed the contracture, and the shape of the neck has remained unchanged: a full-value natural skin integument has been created on the anterior and lateral surface of the neck. Complications (marginal necrosis of the transplanted flaps), recorded in 10% of the patients, have not much influenced the out-come of surgery.
