Laser microsurgical bilateral posterior cordectomy for the treatment of bilateral vocal fold paralysis.
We performed a prospective study to assess respiratory function and voice quality before and after laser microsurgical bilateral posterior cordectomy performed for chronic airway obstruction in patients with bilateral vocal fold paralysis. ⋯ A bilateral approach for laser microsurgical posterior cordectomy combines excellent airway improvement and satisfactory voice preservation. In bilateral vocal fold paralysis, pretreatment and posttreatment clinical data should be evaluated by objective measures.

Prediction of difficult laryngeal exposure in patients undergoing microlaryngosurgery.
Although difficult laryngeal exposure (DLE) is a common problem encountered during microlaryngosurgery, reliable predictors of DLE and grading systems of laryngeal exposure have been scarcely suggested in the field of laryngology. We propose a new classification of laryngeal exposure focusing on the extent of glottic visualization. ⋯ According to the proposed classification of laryngeal exposure, patients with obesity, a muscular neck, or retrognathia are likely to present DLE, and preoperative measurement of the predictors may be useful in preparing for microlaryngosurgery.
