Objective: To investigate the reason for the adhesion of vocal cord after CO2 Laser laryngeal surgery.
Method: One hundred and nineteen patients who were untaken CO2 Laser laryngeal microsurgery.
Result: Among 119 cases, 9 cases of bilateral vocal cord paralysis, 42 cases of vocal cord polyps and 3 cases of precancerous laryngeal lesions did not show vocal cord adhesion after CO2 Laser laryngeal microsurgery. Contrarily, one of 5 cases with laryngeal stenosis, 5 of 41 cases with laryngeal papilloma and 6 of 19 cases with laryngeal carcinoma shew the adhesion of vocal cord after CO2 Laser laryngeal microsurgery.
Conclusion: Through selecting the appropriate patient and surgery spot, processing correctly during and after surgery, using the suitable dosage of laser and reducing the heat radiation, the adhesion of vocal cord can be avoided after CO2 Laser laryngeal surgery.
