[Cancer of the thyroglossal duct]. / Rak shchitoiazychnogo protoka.

The authors present the clinical observation of the cancer of the tongue-lingual duct together with the concise overview of the relevant literature and the discussion of etiology and pathogenesis of this condition.

[The application of the YamIk nasal catheter in the outpatient practice]. / Nazal'nyi kateter IaMIK v ambulatornoi praktike.

The objective of the present study was the enhancement of the effectiveness of the treatment of acute inflammatory diseases of the paranasal sinuses with the unilateral application of a medication mixture containing the vasoconstricting antiseptic agents, antibiotics, and other medications introduced into all paranasal sinuses by means of the procedure performed with the use of the Yamik nasal catheter.

[The cross-plastic correction of the soft tissue defect on the neck with the use of a pectoral flap harvested from the opposite side]. / Perekrestnaya plastika defekta myagkikh tkanei shei pektoral'nym loskutom s protivopolozhnoi storony.

The authors describe a patient presenting with initially multiple metachronous cancer spreading over the right-handed side of the mouth floor and the right-handed part of the lower jaw. The patient who underwent cross-plastic surgery for the correction of the extensive soft tissue defect on the neck with the use of the musculocutaneous pectoral flap with the axial blood supply is described. The observation during the 14 year follow-up period confirmed the good functional outcome of the treatment.

[The application of biopolymer-based antiseptic drugs for the surgical treatment of intranasal and paranasal tumours].

The authors report their experience with the application of the local antiseptic preparation Ambipor for the treatment of operative wound infection in the patients presenting with malignant neoplasms. Ambipor was used in 23 patients receiving surgical treatment of locally advanced intranasal and paranasal tumours. It was shown that the application of ambipor allows decreasing the risk of development of wound infection in the postoperative period.

[Diagnosis and treatment of Wegener's granulomatosis].

The author emphasizes the importance of early diagnosis of Wegener's granulomatosis based on clinical manifestations of the disease with the participation of an otorhinolaringologist. An algorithm of its treatment is proposed that allowed life expectancy to be increased from 8 to 25 years in 10 of the eleven patients.

[Laryngectomy: clinical aspects of preceding tracheostomy].

The objective of this study was to compare results of combined and surgical treatment in 114 patients with stage III-IV T3-4N0M0 laryngeal cancer. Fifty eight patients were treated by laryngectomy without preceding tracheostomy; in the remaining 56 laryngectomy followed tracheostomy (control group). The two groups were matched for all major characteristics, such as age and sex of the patients, histological structure of the tumour, its growth rate and localization, dose and schedule of radiotherapy, extent of surgical intervention. The data obtained were used to evaluate oncological and functional outcomes of the treatment.

[Clinical aspects of tracheostomy as a stage of anterolateral laryngeal resection].

We analysed medical histories of 68 patients with T2-3N0M0 laryngeal cancer who had received combined or surgical treatment. All the patients given the organ preservation treatment were divided into two groups one of which included 36 patients after laryngeal resection without tracheostomy, the other consisted of 32 patients who had undergone laryngectomy with tracheostomy (control). The two groups were matched for age and sex of the patients, the degree of advancement and histological structure of the tumour, its growth rate and localization, dose and schedule of radiotherapy, extent of surgical intervention. The data obtained were used to analyse oncological and functional outcomes of the treatment. Oncological result was estimated based on the survival rate expressed in percentage terms.

[Functional methods for nasal cavity examination in the work of outpatient health facilities].

Three methods for conducting objective functional studies in the ENT cabinet of an outpatient health facility are proposed. The methods may be helpful in the diagnose of acute and chronic disturbances of nasal mucosa.

[Tracheostomy in patients with locally advanced laryngeal cancer].

The authors present the results of treatment of 62 patients with locally advanced laryngeal cancer (LALC) stage III-IV (T3-4NOMO) treated in 1986-2000. The study was made of tracheostomy effects in laryngostenosis following radical operation (not tracheostomy as a stage of laryngectomy) on regional and distant metastasizing as well as on further growth, tumor recurrence and survival in treated patients with LALC. The authors conclude that tracheostomy conducted before radical surgery has a negative effect on heeling the postoperative wound, promotes regional metastasizing and tumor recurrence in patients with LALC, lowers 5-year survival.

[Gas composition of capillary blood of patients with laryngeal cancer in the course of conservative surgical treatment with polymeric endoprosthesis]. / Gazovyi sostav kapilliarnoi krovi bol'nykh rakom gortani na étapakh organosokhraniaiushchego khirurgicheskogo lecheniia s polimernym éndoprotezirovaniem.

Gas composition of capillary blood was studied in 120 patients with laryngeal cancer, primarily of stage IIIa (T3N0M0). Hypoxia was present in all the examinees whether or not laryngostenosis was clinically apparent. The analysis has shown that conservative surgery of laryngeal cancer with application of tubal polymeric endoprostheses corrects ventilatory disorders and improves blood gas composition. The degree of correction of ventilatory disorders depends on the kind of respiratory intraoperative maintenance. Gas composition appeared significantly better in the group of patients exposed to transtracheal high-frequency artificial pulmonary ventilation than in the group exposed to volumic artificial pulmonary ventilation.

[Tracheostomy: a must or elective procedure in laryngeal resection for cancer?]. / Trakheostomiia -- neobkhodimost' ili operatsiia vybora pri rezektsii gortani po povodu rada?

The paper outlines 15-year experience in anesthesia perfection in laryngeal resections with polymeric endoprosthesis (tube endoprosthesis EG 1-4, TU 42-2-467-85) made in 115 patients with laryngeal cancer stage III; presents the analysis of complications in the above resection depending on the time of postoperative and decanulation and anesthesiological procedure. The authors propose methods of shortening the time to decanulation and even to avoid tracheostomy in transcutaneous jet high-frequency artificial lung ventilation.
