The COVID-19 pandemic has created uncertainty regarding the safety and appropriate utilization of minimally invasive surgery (MIS) during this current outbreak. Surgical governing bodies such as Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and the Royal Colleges of Surgery of Great Britain and Ireland have made statements regarding the possibility of COVID-19 release into CO2 insufflant during MIS. The basis for this concern is prior evidence in the literature of other viral pathogen release during laparoscopic surgery. The recommendations are correctly based on caution given the lack of understanding of how COVID-19 compares to other viruses with regard to transmission and presence in CO2 during MIS. In this review we have investigated the available literature on COVID-19 transmission during MIS, address the implications of current and previously published recommendations and discuss steps to mitigate COVID-19 transmission during MIS for staff and patient safety.

We describe the use of the medial sural artery musculocutaneous perforator (MSAP) flap at our institution. It is a relatively new flap, originally described in 2001 for lower extremity defects, that has become increasingly popular for head and neck reconstruction due to its versatility, thinness, pliability, long pedicle, and particularly favorable donor site. It has been described for reconstruction of oral defects, but there is little published on its use in pharyngeal reconstruction. We suggest that the MSAP is an ideal flap for addressing defects caused by pharyngoesophageal stenosis, pharyngeal fistulas, or laryngopharyngectomies. We review 5 cases at our institution from June 2016 to November 2017.

BACKGROUND:The COVID-19 pandemic has significantly impacted medical training. Here we assess its effect on head and neck surgical education. METHODS:Surveys were sent to current accredited program directors and trainees to assess the impact of COVID-19 on the fellow's experience and employment search. Current fellows' operative logs were compared with those of the 2018 to 2019 graduates. RESULTS:Despite reduction in operative volume, 82% of current American Head and Neck Society fellows have reached the number of major surgical operations to support certification. When surveyed, 86% of program directors deemed their fellow ready to enter practice. The majority of fellows felt prepared to practice ablative (96%), and microvascular surgery (73%), and 57% have secured employment to follow graduation. Five (10%) had a pending job position put on hold due to the pandemic. CONCLUSIONS:Despite the impact of the COVID-19 pandemic, current accredited trainees remain well-positioned to obtain proficiency and enter the work-force.

Introduction: Non-tuberculous mycobacteria (NTM) is an intracellular microorganism that causes cavitary disease and nodular bronchiectatic disease of the lung. Patients with NTM appear to have impaired swallow function as represented by impaired airway protection and pharyngeal bolus clearance. It is unknown whether impaired swallowing contributes to the pathophysiology of NTM. Our aim is to determine swallow physiology in patients with bronchiectasis and NTM compared with a control group.
Method(s): Video fluoroscopy (VF) was prospectively collected from 195 patients: 132 patients with NTM (90 females; ages 30-90) and 63 agematched and sex-matched controlswith noNTM(39 females; ages 27-92). Two boluses of 3, 5, 10ml thin liquid, two 5ml puree Varibar, and cracker were analyzed per subject (N = 1755 swallows). Outcome measures included ordinal ratings of residue in the valleculae and pyriform sinuses.
Result(s): Inter-and intra-rater reliability of the ordinal ratings were assessed using one-way mixed intraclass correlation coefficients (ICC) (ICC(2,1)) on 20% of the data with good results (intra-rater: ICC = 0.92, 95% range CI 0.70-0.97 and inter-rater: ICC = 0.92, 95% range CI 0.81-0.97). The ratings of residue in the valleculae were significantly higher (worse) in the NTM group compared to the control group for one of the 3mL bolus (p = 0.008), for both 5 mL boluses (p = 0.009 and p = 0.004), both 10mL boluses (p = 0.0005 and p = 0.0006), puree (p = 0.006), cracker (p = 0.005). The ratings of residue in the pyriform sinuses were also significantly higher in the NTM group for 3 mL boluses (p = 0.0002 and p = 0.01), both 5 mL boluses (p = 0.0003 and p = 0.002), both 10mL boluses (p = 0.001 and p = 0.001), both puree trials (p<0.0001 and p<0.0001).
Conclusion(s): Future work is needed to elucidate responsiveness to swallowing treatment for patients with NTM
