[Differential approach to the use of drug ultraphonophoresis for scars].

A differential approach to administration of drug ultraphonophoresis (gel contractubex, collitin, elastolitin) in scarry deformations is proposed. The analysis of 82 treatment outcomes has shown that early after trauma (on day 6-12) it is more beneficial to use ultraphonophoresis (UPP) of heparin-containing compounds improving blood rheology, e.g. lidase. This prevents development of pathological scars. Later, when the scar tissues has already formed, more effective is UPP of enzyme medicines with fibrinolytic properties (collitin, elastolitin). Differentiated choice of UPP in scar therapy reduces the time of rehabilitation considerably.

[Improving surgical treatment of children with acquired cicatricial stenosis of the larynx and cervical part of the trachea].

Results of surgical treatment of 144 children with acquired cicatricial stenosis of the larynx and cervical compartment of the trachea were analyzed retrospectively. It was found that a temporizing policy was preferable after the first complaints were voiced. They should be operated no earlier than 18 months after stenosis development. In the case of insignificant cicatricial changes CO2 laser treatment was recommended whereas in the case of concentric large scars plastic surgery with an exterior access was to be used. Therapeutic results also depended on the etiology of the pathology. In children with cicatricial stenosis, that developed after intubation trauma of an intact larynx, the results were better. Repeated surgery of small scars produced a high success rate when CO2 laser was used between months 3 and 7. In the case of concentric scars surgical intervention was indicated during months 7-12 after the first operation, with laryngotracheoplasty being the method of choice.

[Surgical treatment of children with cicatricial stenoses of the larynx and trachea].

The present authors recommend a modification of Ivanov's method suggested by their treatment of 41 children, aged 4 to 15 years; 12 patients suffered from stenosis and 29 patients from atresia of the larynx and trachea, which resulted from surgical intervention required by the complications of extended nasotracheal intubation and subsequent tracheotomy. The modified procedure is as follows. In order to enlarge the laryngeal or tracheal lumen, skin is cut and one or two triangle-shaped skin flaps are dissected; their tops are sutured to the anterior wall of the above organs cut along the median line. In order to distend the larynx, redressment of the cricoid cartilage is needed. He-Ne laser irradiation (of 20 mW/cm2 with a wavelength of 632.8 nm) and collagenase and elastase enzymes stimulate repair and prevent secondary cicatrization of post-operative wound. The lumen is formed using a T-shaped silicon tube. Out of 4 patients followed-up during the last 5 years, 21 were decannulated, 12 developed good laryngotracheostoma, 5 of which required suture of wound. Only 8 patients who had laryngotracheostoma needed surgical intervention due to repeated cicatrization. In 4 of these patients, allogenic cartilage was used for support, and polymer paste Polytel was applied to eliminate laryngeal, tracheal or esophageal fistulas.
