[Application of endoscope assisted curved laryngoscopy technique in transoral laryngopharyngeal minimally invasive surgery].

Objective

To explore the possibility of endoscope assisted curved laryngoscopy technique applied in transoral laryngopharyngeal minimally invasive surgery and evaluate the advantages of this technique.

Methods

Eight patients with huge benign lesions in larynx and pharynx undergoing transoral microsurgery at Peking University Third Hospital between February 2016 and February 2017 were enrolled in this study.The diagnosis included cyst at the base of tongue in two patients, cysts in the epiglottis in two patients, hemangioma in two patients, multiple masses of the hypopharynx and amyloidosis in supraglottic area in one patient each.The time and exposure during surgery, occurrence rate of complication and conditions of following-up were recorded.

Results

The mean time of surgery was 20 min, the exposure was satisfying.There was no obvious complication after surgery.No residual or recurrent lesion was observed after 1 to 12 months follow-up(mean time 4.5 months).

Conclusion

The endoscope assisted curved laryngoscopy technique has advantages in shortening the time of surgery, improving exposure and reducing the rate of complication and recurrence.
