[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.
