OBJECTIVE: To evaluate microvascular reconstruction of a vertical hemipharyngolaryngectomy (VHPL) defect for @entity957 . DESIGN: Retrospective analysis of medical records. SETTING: Tertiary care referral center. @entity1 : Thirty-two @entity1 who underwent a VHPL. MAIN OUTCOME MEASURES: Assess the surgical technique and safety of VHPL and review the functional parameters of swallowing and decannulation. RESULTS: The classification was composed of 3 types of VHPL according to the extent of resection: limited VHPL (type I), resection at the lateral border of the conus elasticus to preserve both vocal cords (n = 10); total VHPL (type II), removal of a vertical section of the thyroid cartilage through the anterior commissure to the upper border of the cricoid cartilage with preservation of 1 vocal cord (n = 12); and extended VHPL (type III), inclusion of a supraglottic laryngectomy (type IIIa) (n = 6) or partial cricoid cartilage resection (type IIIb) (n = 4). A radial forearm free flap that included the @entity924 was used for reconstruction in 31 @entity1 , and an anterolateral thigh flap was used in 1 @entity1 . There was no perioperative mortality, and there was 100% free flap survival. Oral realimentation and tracheotomy weaning were achieved a mean of 33 and 32 days postoperatively, respectively. In 25 @entity1 observed for longer than 6 months, the recurrence rate was 28% (7 of 25), and 5-year disease-specific survival was 64%. CONCLUSION: Microvascular reconstruction of VHPL offers a wider resection with promising functional results for @entity189 .
