Surgical Management of Cricotracheal Invasion by XXXX .

@entity1 @entity3557
BACKGROUND: In general, @entity1 with @entity3557 ( @entity3557 ) have an excellent postoperative prognosis. Those with cricoid and/or tracheal @entity3557 invasion, however, are at a higher risk of postoperative morbidity and airway insufficiency. METHODS: We investigated postoperative airway outcomes, locoregional recurrence, and survival rates in @entity1 with @entity3557 who underwent cricotracheal resection. The records of @entity3557 @entity1 who underwent surgery at our institution between 1981 and 2009 were reviewed retrospectively, and 110 @entity1 with cricotracheal invasion were enrolled. Curative resection was performed in all @entity1 , and cricotracheal function was preserved or reconstructed when possible. RESULTS: Of the 110 @entity1 , 57 and 53 @entity1 had superficial and intraluminal invasion of the larynx, respectively. After the initial surgery, the 10-year disease-specific survival rates were 90.8 and 44.4  % in @entity1 with superficial and intraluminal invasion of the cricotracheal area, respectively. Only six @entity1 (5.5  %) had an isolated upper aerodigestive tract recurrence. Five @entity1 were managed with an additional window resection as salvage surgery. Consequently, only one @entity1 (0.9  %) underwent total laryngectomy. Altogether, 31 @entity1 (28.0  %) had a permanent stoma, 9 and 15 of which were caused by cricotracheal invasion and invasion of other aerodigestive structures, respectively. CONCLUSIONS: Window resection for intraluminal cricotracheal invasion by @entity3557 produced good surgical outcomes that resulted in a low local recurrence rate and survival rates that resembled those associated with other surgical treatments. Treatment of multiple organ invasion of the aerodigestive tract was necessary to improve postoperative functional outcomes in these @entity1 .
