title: Role of CT Scan in Decision Making Prior to Approximation Laryngoplasty.
abstract: To evaluate the role of CT scan prior to approximation laryngoplasty (AL). Occasionally, postoperative results in AL are unsatisfactory. The reasons for failure may be an incomplete closure of the phonatory gap or improper size of the implant or implant migration. The role of CT scan in planning the steps of surgery in cases of AL especially in revision cases is discussed in three cases of unilateral vocal fold paralysis. Preoperative CT larynx, especially in revision AL cases, helps plan steps of surgery by deciphering implant material, size, shape and position used in previous surgery.
