[A case of successful surgical treatment of labyrinth fistula in the sole hearing ear].

The objective of this communication is to demonstrate success of the surgical intervention on the sole hearing ear in the presence of absolute indications for such treatment, viz. the presence of cholesteatoma and labyrinth fistula (LF). The sensorineural loss of hearing is a rather common serious complication of LF surgery in the patients with cholesteatoma.

[Our experience with the application of collagen-based preparations in reconstructive surgery of the middle ear].

This paper summarizes our experience with the application of collagen-based preparations for reconstructive surgery of the middle ear. The best morphological results (88.46%) were obtained by the closure of extensive defects with the Oblecolum membrane as a temporary supporting structure and the outer atraumatic dressing for the tympanic transplant (in 30 patients) or by the use of the compact-porous explants from the "Sanguicol" preparation as an overlay on the transplant (in 22 patients).

[Clinical features, diagnosis, and treatment of facial nerve lesions in the practical work of otorhinolaryngologyst].

Surgical treatment of persistent facial nerve lesions is currently the sole efficacious method for restoration of the voluntary locomotary function of mimetic muscles. Treatment of facial nerve neuropathy of otogenic nature requires a combined approach with surgical revision of the middle ear as its indispensable component including examination of the intrapetrous segment of the facial nerve canal. Facial nerve conductivity and controllable locomotary function of mimetic muscles are possible to restore by anastomosing this nerve with another (donor) one at the earliest possible stages of paresis development.
