[The causes and management of laryngostenosis in clinical stage I, II laryngeal cancer patients after decannulation].
OBJECTIVE
To investigate the causes and management of laryngostenosis in clinical stage I, II laryngeal cancer patients after decannulation.


METHODS
The causes of seventeen cases laryngostenosis after decannulation were analyzed and various operations were carried out according to the causes. Two cases were treated by laser through fibrolarnygoscope, granulation tissue in laryngeal cavity were resected by selfretcuining laryngoscope in two patients. The laryngeal cavity scar was removed and the epiglotic flap, bi-pedicled myoperichondral flap, platysma myocutaneous flap were utilized to reconstruct the laryngeal functions in ten patients. Three patients were treated by total laryngectomy.


RESULTS
Except for three cases of total laryngectomy, thirteen cases were decannulated successfully after the second operation, decannulation rate was 92.86%.


CONCLUSIONS
The scar hyperplasia and granulation tissue are the major causes of secondary laryngostenosis after decannulation in clinical stage I, II laryngeal cancer patients. Most of them regained own respiration, swallow and voice function.
