[The observation, diagnostics, and treatment of a patient presenting with a vascular branched tumour of the external ear].

This article describes the observation of a clinical case of a vascular branched tumour (hemangioma) of the external ear with special reference to the clinical features and diagnostics of this condition and the methods for its surgical treatment.

[Ionizing radiation and laryngeal cancer].

The cause behind the currently ever increasing number of patients presenting with laryngeal cancer lies not only in the lack of the apprehensive attitude toward oncological diseases among the medical profession but also in the changing conditions of human life and environment. As many as 165 patients suffering from laryngeal cancer of the 490 ones admitted to our clinic had undergone the influence of ionizing radiation before they were allocated to the main study group while the remaining 325 cases made up the control group. The former group included 112 firefighters of the Chernobyl disaster.

[Etiology and pathogenesis of glomus tumours (chemodectomas) of the base of the skull].

The objective of the present work was to describe the poorly known history of the development of the nomenclature of glomus tumours (chemodectomas) of the base of the skull, elucidate etiology and pathogenesis of these neoplasms. The authors present a chronological table illustrating the progress of etiological and pathogenetic studies as well as the surgical treatment of the tumours. The results of analysis and discussion of the controversial issues of the nomenclature are reported.

[The application of the lyophilized xenodermoimplants for the plastic correction of the external auditory canal and nasal septum perforation].

The objective of the present work was to improve the effectiveness of the treatment of atresia of the external auditory canal (EAC). Atresia of external acoustic meatus is a result of a mechanical or thermal injury but can also develop after a surgical intervention for the removal of foreign bodies, benign and malignant tumours. This condition is frequently associated with the narrowing and obliteration of EAC leading to the marked impairment of hearing despite preservation of the middle ear structures.

[Peculiar features of the coagulation, fibrinolytic, and anticoagulation systems of blood in the patients presenting with vascular ENT tumours].

The objective of the present work was to study characteristics of the blood coagulation system in the patients presenting with vascular ENT tumours including the following parameters: a complete blood count, hemorrhage, coagulation, retraction, and blood clot lysis times. The patients with ENT hemangiomas experienced hypocoagulation in the preoperative period in combination with the predominance of the fibrinolytic processes and elevated levels of free heparin. These changes can be interpreted as a protective reaction to prevent intravascular coagulation in the case of the slow blood flow in hemangiomatous cavities.
