[Endolaryngeal surgery and photodynamical therapy of using flexible videoendoscopic devices to treat laryngeal cancer and premalignancy].

Patients with laryngeal cancer (LC) and premalignancy admitted to P.A. Gertsen Moscow Research Oncological Institute were treated by the methods of endolaryngeal surgery making use of flexible videoendoscopic devices, Nd:YAG laser-assisted thermal ablation, argon plasma coagulation, electroresection, and photodynamical therapy.

[Establishment of acannular tracheostoma].

Creation of flat tracheostoma of a stable size is one of the key moments of tracheoesophageal bypass with prosthesis. The authors present original techniques of creation of a wide acannular tracheostoma for rehabilitation of voice function and providing adequate respiration after laryngectomy.

[Reestablishment of the vocal function in patients with pharyngospasm after laryngectomy for laryngeal cancer].

Tracheoesophageal bypass was made in 114 patients after laryngectomy for reestablishment of voice. Of them, 17 (14.4%) patients had pharyngospasm which hinders voice recovery.

[Clinical and acoustic characteristics of tracheoesophageal bypass with prosthesis].

The authors analyse different aspects of tracheoesophageal bypass with prosthesis, how to prolong operation of voice prostheses. It is shown that replacement of the prostheses is frequently necessary not because of wear but rather due to fungal or microfloral affection. Radiotherapy had no adverse effects on prosthesis.
