RESUMEN
BACKGROUND: Chronic rhinosinusitis (CRS) affects up to 16% of the population. When medical treatment fails, endoscopic sinus surgery (ESS) is considered. The value of resecting the middle turbinate to optimize surgical outcomes has been hypothesized but remains controversial and unproven. Whether the middle turbinate should be left in place or resected is controversial. Our objective is to determine if middle turbinectomy improves objective surgical outcomes after ESS. METHODS: Sixteen patients (15 men, 15 primary surgery) undergoing bilateral complete ESS for CRS with nasal polyposis were recruited. Nasal cavities were randomized so that middle turbinectomy was performed on one side while the middle turbinate was preserved on the other. Each participant acted as their own control. Nasal cavities were compared using Perioperative Sinus Endoscopy (POSE) and Lund-Kennedy (LKES) scores pre-operatively, and at 1, 3 and 6 months after ESS. Results were analyzed using Wilcoxon signed-rank test. RESULTS: Pre-operatively, the POSE (12.4 ± 2.9 vs 12.8 ± 2.6, p = 0.33, for the preserved side and the resected side, respectively) and LKES (5.0 ± 1.0 vs 4.8 ± 1.2, p = 0.33) scores were similar between sides. During follow up, resection was associated with more crusting at 1 month following ESS (1.0 ± 0.7 vs 0.4 ± 0.6, p = 0.02). There was a small, but statistically significant, difference between the nasal cavities at 3 months, where the resected side showed better endoscopic appearance (2.0 ± 2.2 vs 3.4 ± 2.8, p = 0.01). No difference was found at 6 months. Frontal sinus scores were similar between sides at 6 months (0.7 ± 0.5 vs 0.7 ± 0.5, p = 1.00). CONCLUSION: Our results show no sustained objective endoscopic benefit of routine middle turbinectomy, at least within the first six postoperative months, in patients undergoing primary ESS for CRS with polyposis.

BACKGROUND: Oral cavity squamous cell carcinoma (SCC) represents the most common SCC affecting the head and neck region. Long-term survival of patients with oral cavity SCC is adversely affected by lymph node metastasis and further decreased by the presence of lymph node extracapsular spread (ECS). METHODS: Using a case-control design, preoperative CT scans from patients with oral cavity SCC and metastatic lymphadenopathy were evaluated by 2 independent neuroradiologists, blinded to the study, for a number of radiologic parameters, including central node necrosis. Multivariate logistic regression was used to identify parameters independently predicting pathologic ECS. RESULTS: For both neuroradiologists, central node necrosis was a significant predictor of ECS, with high interrater agreement (kappa = 0.71). On multivariate analysis, only central node necrosis independently predicted ECS (odds ratio [OR] = 12.1; 95% confidence interval [CI] = 1.24-119). Central node necrosis predicted ECS with 91% sensitivity and 88% negative predictive values. CONCLUSION: Our findings suggest that central node necrosis on preoperative CT scans is strongly associated with the presence of ECS.
