RESUMEN
Objectives: Investigate opioid usage and postoperative pain in patients undergoing head and neck free flap surgery. Methods: A retrospective review of 100 consecutive patients undergoing head and neck free flap reconstruction at two academic centers was performed. Data captured included demographics, postoperative inpatient pain, pain at postoperative visits, morphine equivalent doses (MEDs) administration, medication history, and comorbidities. Data were analyzed using regression models, χ 2 tests, and student's t-tests. Results: Seventy-three percent of patients were discharged with opioid medication, with over half (53.4%) continuing to take opioids at their second postoperative visit, and over one-third (34.2%) continuing to take them around 4-month postoperatively. One out of every five (20.3%) opioid-naïve patients chronically took opioids postoperatively. There was a poor association between inpatient postoperative pain scores and daily MEDs administered (R 2 = 0.13, 0.17, and 0.22 in postoperative Days 3, 5, and 7, respectively). Neither preoperative radiotherapy nor postoperative complications were associated with an increase in opioid usage. Conclusions: For patients undergoing head and neck free flap operations, opioid medications are commonly used for postoperative analgesia. This practice may increase the chance an opioid-naïve patient uses opioids chronically. We found a poor association between MEDs administered and patient-reported pain scores, which suggests that standardized protocols aimed at optimizing analgesia while reducing opioid administration may be warranted. Level of Evidence: 3 (Retrospective cohort study).
RESUMEN
OBJECTIVE/HYPOTHESIS: This study aimed to determine the incidence of facial pressure injuries associated with prone positioning for COVID-19 patients as well as to characterize the location of injuries and treatments provided. METHODS: This was a retrospective chart review of 263 COVID-19 positive patients requiring intubation in the intensive care units at MedStar Georgetown University Hospital and MedStar Washington Hospital Center between March 1st and July 26th, 2020. Information regarding proning status, duration of proning, presence, or absence of facial pressure injuries and interventions were collected. Paired two-tailed t-test was used to evaluate differences between proned patients who developed pressure injuries with those who did not. RESULTS: Overall, 143 COVID-19 positive patients required proning while intubated with the average duration of proning being 5.15 days. Of those proned, 68 (47.6%) developed a facial pressure injury. The most common site involved was the cheek with a total of 57 (84%) followed by ears (50%). The average duration of proning for patients who developed a pressure injury was significantly longer when compared to those who did not develop pressure injuries (6.79 days vs. 3.64 days, P < .001). CONCLUSIONS: Facial pressure injuries occur with high incidence in patients with COVID-19 who undergo prone positioning. Longer duration of proning appears to confer greater risk for developing these pressure injuries. Hence, improved preventative measures and early interventions are needed.

OBJECTIVES/HYPOTHESIS: To assess the accuracy and reliability of the flow coupler relative to the implantable arterial Doppler probe in postoperative monitoring of head and neck free flaps. STUDY DESIGN: Retrospective single-institution study, April 2015 to March 2017. METHODS: Both the venous flow coupler and arterial Doppler were employed in 120 consecutive head and neck free flap cases. When Doppler signal loss occurred, flaps were evaluated by physical exam to determine whether signal loss was a true positive necessitating operating room takeback. Sensitivity, specificity, and false positive rate (FPR) were recorded for each device. Logistic regression was conducted to identify user trends over time. RESULTS: Eleven of 120 patients (9.2%) required takeback, 10 from venous thrombosis and one from arterial thrombosis. Permanent signal loss (PSL) occurred in the flow coupler in all takebacks; PSL occurred in the arterial Doppler only in the case of arterial thrombosis. Salvage rate was 9/11 (81.8%). For the flow coupler, sensitivity was 100%, specificity 86.4%, and FPR 13.6%. For the arterial probe, sensitivity was 9.1%, specificity 97.1%, and FPR 2.9%. A 4.1% decrease in false positives with each additional flow coupler use was observed. CONCLUSIONS: Monitoring the vein via flow coupler has high sensitivity in identifying vascular compromise compared to the arterial probe, especially for venous thrombosis. There is moderate FPR; this decreases with increased usage and, when supplemented with physical examination, does not result in unnecessary takebacks. The flow coupler can be a valuable tool in postoperative monitoring of head and neck free flaps. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:812-817, 2018.

PURPOSE: Head and neck squamous cell carcinomas exhibit variable sensitivity to inhibitors of the PI3K/mTOR pathway, an important target of genomic alterations in this cancer type. The mitogen-activated protein kinase kinase (MEK)/ERK/activator protein 1 (AP-1) and nuclear factor-κB (NF-κB) pathways are also frequently co-activated, but their roles in resistance mechanisms to PI3K/mTOR inhibitors and as therapeutic targets in head and neck squamous cell carcinoma (HNSCC) are not well defined. EXPERIMENTAL DESIGN: We determined the IC50s of dual PI3K/mTOR inhibitor PF-05212384 (PF-384) by XTT assays in 14 HNSCC lines with PI3K/Akt/mTOR cascade alterations. In two resistant models, we further characterized the molecular, cellular, and in vivo attributes and effects of combining PF-384 with MEK inhibitor PD-0325901 (PD-901). RESULTS: PF-384 IC50s varied between 0.75 and 133 nmol/L in 14 HNSCC lines with overexpression or mutations of PIK3CA, and sensitivity correlated with increased phospho-AKT(T308/S473). In resistant UMSCC-1 and -46 models, PF-384 increased G0-/G1-phase accumulation but weakly induced sub-G0 cell death. PF-384 inhibited direct targets of PI3K/mTOR, but incompletely attenuated co-activated ERK and UMSCC-1 xenograft growth in vivo. PD-901 strongly inhibited MEK/ERK targets, and the combination of PF-384 and PD-901 inhibited downstream NF-κB and AP-1 transactivation, and IL8 and VEGF production in vitro. PD-901 potently inhibited tumor growth alone and with PF384, enhanced antiproliferative, apoptotic, and anti-angiogenesis activity in vivo. CONCLUSIONS: PI3K/mTOR inhibitor PF-384 exhibits variable activity in a panel of HNSCC cell lines with differing PIK3CA expression and mutation status. MEK inhibitor PD-901 overcomes resistance and enhances antitumor effects observed with PF-384 in vivo.

With the increasing availability of the Internet in the United States, patients are more frequently seeking medical information online. Oftentimes, the medical information that patients find on traditional websites is unreliable. It is a physician's duty to ensure that patients are being educated properly. Providing sound medical information through social media websites is one way in which physicians may accomplish this goal, while also improving clinic reputation, patient volume, and doctor-patient communication.

The objective of this article is to describe our surgical technique for accessing orbital and supraorbital ethmoid sinus mucoceles and the novel application of a biliary T-tube to stent and redirect mucociliary flow into the frontal recess. We describe in technical terms our surgical approach and the use of an 8-Fr pediatric biliary T-tube as a paranasal sinus stent with demonstrative case reports. Four patients have been successfully managed employing the endoscopic trans(naso)orbital approach to access and marsupialize supraorbital and superiorly located orbital mucoceles without egress to the frontal recess. Patency of drainage was maintained by utilizing a flexible, pediatric, biliary T-tube that is inserted via an above (trephination) and below (endoscopic) approach in three patients, and without the need for stenting in one patient (median follow-up, 14.5 months). The presented surgical strategy is safe and effective in accessing and maintaining long-term patency of problematic supraorbital and superiorly located intraorbital mucoceles without communication to the frontal recess.
