Incision will be made at the lower border of thyroid cartilage under aseptic measures. Skin flaps will be raised in sub-platysmal plane, strap muscles will be separated in the midline to expose the laryngeal cartilaginous framework. A simple laryngeal window approach will be used to place the Ethicon prolene mesh 6 x 6cm Swiss roll, secured with prolene 2/0 suture trimmed to the required size. Post op voice analysis will be done on 7th day and 14th post-operative day. Monthly follow up will be advised after that.","id":"OG000","title":"Prolene Mesh Implant"}],"paramType":"MEAN","reportingStatus":"POSTED","timeFrame":"Preoperative and 14th Postoperative day","title":"Change in Mean Phonation Time","type":"PRIMARY","unitOfMeasure":"seconds"}
