Objective Identify trends in swallowing outcomes in p16+ oropharyngeal squamous cell carcinoma following neoadjuvant chemotherapy+surgery (NAC+S) versus neoadjuvant chemotherapy+surgery+radiation (NAC+S+R). Study Design Cohort study. Setting Single academic institution. Methods Swallowing outcome was measured using a validated questionnaire, MD Anderson Dysphagia Inventory (MDADI). MDADI scores were compared between NAC+S and NAC+S+R groups in short‐term (<1 year), middle‐term (1‐3 years), and long‐term (>3 years). Clinical factors associated with MDADI scores were explored using a linear mixed model. Statistical significance was established at p < .05. Results Sixty‐seven patients met the inclusion criteria and were divided into 2 groups: NAC+S (57 [85.1%]) and NAC+S+R (10 [14.9%]). All patients had improved MDADI scores in the middle‐term compared to short‐term (NAC+S: score increase = 3.43, p = .002; NAC+S+R: score increase = 11.18, p = .044), long‐term compared to short‐term (NAC+S: score increase = 6.97, p < .001; NAC+S+R: score increase = 20.35, p < .001), and long‐term compared to middle‐term (NAC+S: score increase = 3.54, p = .043; NAC+S+R: score increase = 9.18, p = .026). NAC+S patients had better MDADI scores than NAC+S+R patients at short‐term (83.80 vs 71.26, p = .001). There was no significant difference in swallowing function in the middle‐term or long‐term. Conclusion Regardless of treatment type, swallowing will likely be improved in the middle‐term and long‐term compared to the short‐term. Patients treated with NAC+S+R will have worse short‐term swallowing function. However, in the middle‐term and long‐term, there is no significant difference in swallowing function between patients treated with NAC+S and NAC+S+R.
Objective: Robin sequence (RS) consists of micrognathia and glossoptosis that result in upper airway obstruction (UAO). In RS patients who undergo tracheostomy, long-term goals include natural decannulation (ND) without further surgical airway intervention. The objective of this study was to identify long-term trends in the rate and length of time to ND. Methods: Retrospective chart review on 144 patients with RS treated from 1995 to 2020 at a pediatric tertiary care center. Patients were grouped by year of tracheostomy. Demographic data, UAO management, postoperative care, complications, and time to decannulation were recorded. Results: Thirty-six patients met the inclusion criteria. Tracheostomy was performed at a median age of 45.5 days. 19 (53%) patients experienced ND at a median time of 66.1 months. ND rate was higher in non-syndromic patients (93% non-syndromic vs 27% syndromic; P < .0001) and during the first study period (1995-2006: 78%, 2007-2020: 28%; P = .003). Cox proportional-hazard regression demonstrated that white race [aHR 0.15 (0.03-0.8); P = .023] and higher birthweight [aHR 0.9 (0.8-0.98); P = .018] were associated with a higher likelihood of ND while a syndromic diagnosis had a negative association with ND [aHR 12.5 (3.3-50.0); P < .001]. Conclusions: Our study documented that ND in patients with RS who underwent tracheostomy was significantly associated with ethnicity, birthweight, and syndromic status. The negative impact on successful ND was most observed in patients with syndromic associations. Additionally, ND rates are lower in the 2007 to 2020 subgroup. We suspect this is because alternative management techniques such as tongue lip adhesion and mandibular distraction osteogenesis became primary surgical treatment in severe RS upper airway obstruction at our institution starting in 2007.
