[Characteristics of diagnosis and surgical treatment of various forms of congenital temporal bone cholesteatoma]. / Osobennosti diagnostiki i khirurgicheskogo lecheniya razlichnykh form vrozhdennoi kholesteatomy visochnoi kosti.

OBJECTIVE: To conduct a retro- and prospective analysis of the clinical characteristics and results of surgical treatment of patients with congenital temporal bone cholesteatoma. PATIENTS AND METHODS: On the basis of the SPb Scientific Research Institute of ENT of the Ministry of Health of Russia 23 patients were diagnosed with congenital temporal bone cholesteatoma for the period from 2011 to 2018. There were 11 men (47.8%), 12 women (52.2%), the age of patients - from 2 to 44 years. The M.J. Levenson criteria were used to verify congenital middle ear cholesteatoma. (1986). According to intrasurgery findings, we identified congenital cholesteatoma of the middle ear stages according to the ChOLE classification. Other types of congenital temporal bone cholesteatoma included the patients with congenital atresia of the external auditory opening, combined with congenital temporal bone cholesteatoma; we found a patient with exostoses obstructing the external auditory canal combined with congenital cholesteatoma of the middle ear; and a patient with congenital cholesteatoma of the temporal bone pyramid. RESULTS: An increase in the incidence of congenital temporal bone cholesteatoma was noted, which is probably due to increased awareness of specialists and the wider use of imaging research methods. A relationship was revealed between the stage of congenital cholesteatoma according to the ChOLE classification and the necessary volume of surgical intervention. Of the total number of cases of congenital temporal bone cholesteatoma, 26.1% were the patients with anomalies in the development of the outer and middle ear. CONCLUSIONS: All patients with suspected congenital temporal bone cholesteatoma require a temporal bone MSCT and middle ear MRI in DWI mode.

[Skull base defects multilayer plasty in patients with spontaneous cerebrospinal fluid leak: our experience]. / Opyt primeneniia mnogosloinykh transplantatov v plastike defektov osnovaniia cherepa u bol'nykh so spontannoi nazal'noi likvoreei.

Spontaneous cerebrospinal fluid (CSF) leak is one of the types of non-traumatic CSF leaks in which the etiologic factor is unknown. Skull base defects transnasal endoscopic plasty is the initial method of surgical repair of spontaneous cerebrospinal fluid leaks. METHODS: Forty-five patients with spontaneous CSF leaks were managed using multilayer transplant technique. The basic choice criteria of endoscopic transnasal surgical approach and materials to reconstruction of skull base defects were the size of defect and its localization. In all cases pediculated flaps in combination with free graft were used. RESULTS: In 43 (96%) cases CSF leaks was successfully managed in primary surgery, which indicates high efficiency of the described surgical interventions.

[Acute and chronic laryngitis in the subjects engaged in the voice and speech professions]. / Ostrye i khronicheskie laringity u professionalov golosa.

Laryngitis is one of the commonest causes of dysphonia in the subjects engaged in the voice and speech professions. This condition can be either associated with the professional activities or related to voice fatigue. It is a common practice to distinguish between acute and chronic forms of occupational laryngitis. The main factors responsible for development of both conditions include the non-observance of directions concerning the protection and hygiene of the speaking and singing voice. The present study included 478 (100%) subjects engaged in the voice and speech professions presenting with the diagnosis of acute or chronic occupational laryngitis who applied for medical assistance to our Phoniatric Care Department. The clinical state of their larynx was evaluated with the use of the videoendostroboscopic technique. Acute laryngitis was diagnosed in 103 (21.5%) of the examined subjects while the remaining 375 (78.5%) ones presented with chronic laryngitis. A characteristic feature of acute occupational laryngitis documented in 38 (36.9%) examined professional voice users with this condition (practically healthy in all other respects) was the development of this disorder as a result of overloading the speech organs. On the contrary, viral and/or bacterial laryngitis revealed in 65 (63.1%) of the patients was preceded by acute respiratory symptoms. A total of 62 (16.5%) patients suffered from chronic occupational laryngitis attributable to overloading of the organs of speech during protracted periods. The remaining 313 examined professional voice users were found to present with various forms of chronic laryngitis including catarrhal laryngitis in 175 (46.7%) of them, edematous-polypoid and atrophic forms in 32 (8.5%) and 19 (5.1%) subjects respectively. The main etiological factors underlying the development of all the tree forms of chronic laryngitis were smoking, chronic tonsillitis, gastroesophageal reflux disease, bronchial asthma, and diabetes mellitus.

[Mucolytic therapy of sinusitis].

The authors overview the articles concerning the treatment of sinusitis with the use of mucolytic preparations published in the Russian-speaking and foreign literature during the period from 1987 to 2013. Special attention is given to GeloMyrtol and GeloMyrtol forte therapy. The analysis of the papers of interest has demonstrated that the herbal medicinal products based on standardized myrtol have a number of advantages over other preparations of the same type. It is concluded, taking into consideration the evidence-based effectiveness of GeloMyrtol and simplicity of its application, that this remedy can be prescribed to the patients suffering from sinusitis.

[The function of the oxidant-antioxidant system in patients with laryngeal cancer]. / Sostoianie oksidantno-antioksidantnoi sistemy u bol'nykh rakom gortani.

Lipid peroxidation and antioxidant system were studied at hospital admission, on postoperative day 1, 3 weeks and half a year after surgery in 86 patients with different stages of laryngeal cancer. A correlation is stated between lipid peroxidation disturbances and the defects in the protective antioxidant system. Low-frequency laser irradiation of autoblood produced a clinically beneficial effect and stabilized biochemically the relations between lipid peroxidation and antioxidant systems.

[Contact laser surgery in the treatment of laryngeal neoplasms]. / Rezultaty kontaktnoi lazernoi khirurgii novoobrazovanii gortani.

YAG-ND laser contact surgery in combination with tracheal puncture jet ventilation of the lungs were used in managing 128 patients with laryngeal cancer (T1-T2) and 129 patients with benign lesions of the larynx. A complete response was achieved in 97.3% of stage I and 94.4% of cancer stage II patients. The recurrences occurred in 7 out of 129 patients with benign lesions.

Basing on the results obtained in 129 patients with benign and 135 ones with malignant laryngeal tumors the author provides theoretical and practical grounds for introduction of high-energy YAG laser under contact regimen in endolaryngeal microsurgery of relevant tumors. Advantages of the method, indications and contraindications to its application are considered in detail.
