[The possibility of using соformulated intranasal drugs after surgical correction of nasal breathing].

One of the major causes of chronic nasal obstruction is the nasal septum deformation and increase of the lower nasal turbinates. The number of septoplasty--operations ranges from 14% to 44,2% of all ENT-operations. The results of surgery are swelling of the tissues and damaged ciliar epithelium, that leads to the inparament of the mucociliar transport. In the postoperati e period the nasal cavity should be cleaned. Drugs, that are used, should reduce swelling, improve regeneration and should not supress ciliar activity. The results of supervisory, non-interventional study have shown, that application of Nasiс after septoplasty and submucose vasotomy of inferior nasal turbinates increases reparative process and leads to more rapid recovery of respiratory function of nasal cavity.

[The Possibilities of Cell Technologies in the Treatment of Cicatricial Lesions of the Vocal Folds].

The article is a brief review of publications devoted to the problem of persistent dysphonia. The main cause of voice disorders is the scarring of the vocal folds resulting from trauma, surgical manipulation, inflammatory process. Treatment of cicatricial lesions of the vocal folds remains a challenge, as far as existing methods do not ensure the recovery of the ultrastructure of the vocal folds. The authors present modern data on the structure of the vocal folds at the cellular level. Considered pathologic processes occur in different stages of scarring. Applied technologies of phonosurgery and conservative treatment, their effectiveness and shortcomings are covered. Analysis of experimental research conducted in the world demonstrates the promise of using the methods of tissue engineering to treat scarring of the vocal folds and to restore the microstructure of the latter. Identified current issues remain unresolved, which leads to the need for further experimental and clinical studies in the treatment of this pathology.

[Morphological marker of tumor progression in laryngeal cancer].

Dynamic observation of 32 patients with laryngeal cancer, treated with radiotherapy and combination therapy, was performed using diagnostic technology "Litos-system", including the definition of serum morphotypes by marginal dehydration of biological fluids. In nine of them, on the background of the treatment, there was continued growth of the tumor. In the blood serum seven of nine patients had special microspheroliths, characterized by the presence of "wavy" structures. Such "wavy" microspheroliths could be seen as a harbinger of the continued growth of the tumor, because after their appearance there were detected signs of clinical progression. Apparently, the appearance of mentioned "wavy" structures in the patient's blood is a result of release into the blood of qualitatively new macromolecules produced by a clone of malignant tumor cells.
