[Improvement of the general anesthesia method for microlaryngoscopic surgery with self-retaining laryngoscope: a study on 31 cases].

OBJECTIVE
To investigate the improvement of general anesthesia method for microlaryngoscopic surgery with self-retaining laryngoscope.


METHOD
31 cases with laryngeal lesion who had undergone the microlaryngoscopic operation with self-retaining by anesthesia were reviewed retrospectively from October 1, 1997 to December 31, 2000.


RESULT
All patients undergone the microlaryngoscopic surgery and their specimens were examined by pathology, 30 cases were benign lesion, 1 case was squamous cell cancer of the vocal cord. Their voice recovers very satisfactorily except for 2 patients. There were no recurrence after 6-38 months follow-up.


CONCLUSION
This study suggests that the general aneathesia with plastic jet ventilating tube controlling respiratory for microlaryngoscopic surgery is easier, more effective and safer than the other methods.
