[Use of biomaterial alloplant and homeostatic material surgicel in reconstructive laryngeal and tracheal surgery].

Posttraumatic stenosis of the larynx, cervical and upper choracic parts of the trachea was treated surgically using biomaterial (cartilage) alloplant and hemostatic material sergisel with an antibacterial effect. Cartilage implantation into the lateral tracheal walls was made in 10 patients, creation of the lateral and anterial walls of the larynx and trachea was made in 4 patients. Short before the cartilage placing in the tissues it was packed with material sergisel. Further adequate dilatation prosthetic reconstruction of the trachea for 3-4 months with application of silicon T-tube allowed complete decanulation of 7 patients (50%) -- they have undergone plastic surgery of the anterior tracheal wall. The rest 7 patients are at the stage of dilatation of the tracheal passage with a good response to therapy. Thus, a positive treatment result of alloplant and sergisel (implant and hemostatic materials, respectively) allows us to recommend these materials for reconstructive surgery of hollow organs of the neck.

[Therapeutic algorithm in stenosis of the larynx and cervical trachea of various etiology].

An algorithm of the treatment of laryngo- tracheal stenosis (LTS) is proposed to raise efficacy of surgical treatment of LTS and to reduce the number of postoperative complications. The algorithm comprises adequate preoperative preparation of the patients including pharmacological prophylaxis of inflammation in the operative zone; effective use of laryngotracheoplasty; prophylaxis of postoperative scarring including reconstruction of created laryngotracheal passage and administration of medicines influencing general and local immunity, tissue metabolism, repair in the region of postoperative inflammation. The efficacy of the algorithm was followed up un 54 (33.7%) patients with laryngostenosis and 106 (66.3%) patients with laryngo-tracheal stenosis. The algorithm application help rehabilitate all the patients with laryngeal stenosis and 92 (86.8%) patients with laryngo-tracheal stenosis.

[The treatment of laryngeal papillomatosis with interferon inducers]. / Lechenie papillomatoza gortani induktorami interferona.

Seventy three patients aged 16 to 88 years who had laryngeal papillomatosis (LP) were followed up. Microsurgical endolaryngeal removal of laryngeal papillomas was made in all the patients. The interferon inducers amixine and cycloferon as antirecurrent drugs were used in 45 patients by the regime the authors developed by taking into account the interferon status and cellular immunity of patients. The criteria for the efficiency of treatment were their improved interferon status and longer remission. The efficiency of treatment with amixine and cycloferon was 72 and 80%, respectively. Thus, the use of a sparing microsurgical intervention in combination with interferon inducers may be regarded as the method of choice in the LP treatment.

[The use of superior and inferior skin trapeziform flaps in treating cicatricial stenoses of the larynx and trachea occurring after extensive laryngeal cancer operations]. / Primenenie verkhnego i nizhnego kozhnykh trapetsievidnykh loskutov, pri lechenii rubtsovykh stenozov gortani i trakhei, voznikshikh posle rasshirennykh laringoonkologicheskikh operatsii.

Partial laryngeal resections and extended laryngectomies for advanced laryngeal cancer bring scarry stenoses in 22-33% of cases. To correct scarry laryngostenoses and stenosed cervical trachea, the authors propose reconstructive surgery using anterior and inferior skin trapeziform flaps stimulating formation of wide stroma. The frequency of laryngostenoses and stenosis of cervical part of the trachea after operations for laryngeal cancer decreased 2-fold due to application of trapeziform flaps, antibacterial powder iodopor and suturing material kaproiod.
