ObjectiveVoice outcomes following medialization laryngoplasty (ML) for unilateral vocal fold paralysis (UVFP) were compared to those who underwent ML plus arytenoid adduction (AA) (ML+AA).MethodsSingle institution retrospective review of patients with UVFP undergoing ML and ML+AA (2009–2017). Demographic information and history of laryngeal procedures were collected. Preoperative and postoperative Voice Handicap Index‐10 (VHI‐10) and Consensus Perceptual Auditory Evaluation of Voice (CAPE‐V) were assessed.ResultsOf 236 patients, 119 met study criteria. Of those, 70 (59%) underwent ML and 49 (41%) underwent ML+AA. Significant differences between groups at baseline were found for age at time of thyroplasty (P = 0.046), VHI‐10 scores (P < 0.001), and CAPE‐V scores (P = 0.007). Baseline VHI‐10 scores for ML+AA (28 ± 7) were greater than those for ML alone (24 ± 7). At 12 months, overall VHI‐10 scores improved compared to baseline for both groups (ML+AA = 9 ± 7, ML = 16 ± 9); however, there was greater improvement for the ML+AA group compared to ML group (P = 0.001). CAPE‐V scores at 3 or 12 months improved, but differences between the groups were not statistically significant once controlled for covariates.ConclusionBased on current findings, patients who undergo ML+AA likely have greater voice handicap at baseline compared to those undergoing ML alone. Patients selected for ML+AA improve as much or more than those who underwent ML alone. This highlights the importance of appropriate selection of candidates for AA.Level of Evidence4Laryngoscope, 129:1876–1881, 2019

Background There is little data regarding postoperative outcomes of patients with obstructive sleep apnea (OSA) undergoing skull base surgery. The purpose of this study is to determine an association between risk factors and proximity of cerebrospinal fluid (CSF) leak to surgery in patients with OSA undergoing endoscopic skull base surgery. Methods A retrospective review of neurosurgical inpatients, with and without OSA, at a tertiary care institution from 2002 to 2015 that experienced a postoperative CSF leak after undergoing endoscopic skull base surgery. Results Forty patients met inclusion criteria, 12 (30%) with OSA. OSA patients had significantly higher body mass index (BMI; median 39.4 vs. 31.7, p < 0.01) and were more likely to have diabetes (41.7 vs. 10.7%, p = 0.04) than non-OSA patients; otherwise there were no significant differences in clinical comorbidities. No patients restarted positive pressure ventilation (PPV) in the inpatient setting. The type of repair was not a significant predictor of the time from surgery to leak. Patients with OSA experienced postoperative CSF leak 49% sooner than non-OSA patients (Hazard Ratio 1.49, median 2 vs. 6 days, log-rank p = 0.20). Conclusion Patients with OSA trended toward leaking earlier than those without OSA, and no OSA patients repaired with a nasoseptal flap (NSF) had a leak after postoperative day 5. Due to a small sample size this trend did not reach significance. Future studies will help to determine the appropriate timing for restarting PPV in this high risk population. This is important given PPV's significant benefit to the patient's overall health and its ability to lower intracranial pressure.
