The CT Evaluation of Neoarytenoid Soft Tissue after an Arytenoidectomy during a

Objective: To evaluate the postoperative laryngeal CT findings of neoarytenoid soft tissue at an arytenoidectomy site during a supracricoid partial laryngectomy, and to compare its thickness to the mucosa over the spared arytenoid cartilage. Materials and Methods: Thirty-one patients underwent a supracricoid partial laryngectomy with (n = 14) or without (n = 17) an arytenoidectomy. A postopera-tive laryngeal CT examination was performed to statistically compare the thick-ness of the neoarytenoid soft tissue to the mucosa over the spared arytenoids. Results: The neoarytenoid soft tissue revealed an eccentric prominence in all 14 arytenoidectomy sites. Further, the neoarytenoid soft tissue was consistently thicker than the mucosa over spared arytenoids cartilage (p < 0.01), however did not exceed 11 mm. Conclusion: The eccentric prominence of neoarytenoid soft tissue at the ary-tenoidectomy site during a supracricoid partial laryngectomy should be identified and distinguished from a recurrent mass when compared to spared arytenoid car-tilage on a postoperative laryngeal CT
