Breaking it down: Review and management of sialendoscopy device malfunctions.

PURPOSE: The present study was aimed at determining common causes of sialendoscopy device malfunctions and identifying a uniform algorithm to manage device failures. MATERIALS AND METHODS: The FDA Manufacturer and User Facility Device Experience (MAUDE) database was searched for various keywords related to sialendoscopy. Reports between the dates of December 1, 2009 to March 31, 2020 were downloaded for review and included in the study. Variables such as: device, the iatrogenic injury type, and subsequent surgical or medical intervention were collected and details of the malfunction were categorized based on the type of malfunction. RESULTS: 206 medical device reports were identified; 47 of them which met inclusion criteria (106 were duplicate cases and 53 were irrelevant to the present study). The majority of device malfunctions involved salivary stone extractor baskets (SSEBs), (40/47; 85.1%), followed by malfunctions of balloon dilators (3/47; 6.4%) and sialendoscopes (2/47; 4.3%). Retention of the SSEB was noted in 85% of the SSEB malfunctions. CONCLUSIONS: Given that sialendoscopy is an increasingly popular technique that relies on devices, it is inevitable that device failures will occur for a multitude of reasons. Working to prevent these malfunctions from occurring is the most effective method of harm reduction. Though it is important that sialendoscopists have a discrete, algorithmic approach to manage them when they occur.

Did More Otolaryngology Residency Applicants Match at Their Home Institutions in 2021? Investigating the Impact of the COVID-19 Pandemic.

OBJECTIVE: To compare the proportion of applicants who matched to their home otolaryngology program during the COVID-19 pandemic compared to the previous 5 years. METHODS: A "home program match" status was identified for residents in each PGY level and in incoming interns. The "home match proportion" (HMP) was then calculated for each program for each year from 2016 to 2021. The difference in the distribution of home matches between PGY0 and PGY 1, 2, 3, 4, and 5 were analyzed using the chi-square independence test and Fisher's exact test. Statistical significance was declared at P < .05. RESULTS: A total of 1885 residents were identified from 101 otolaryngology residency programs. The distribution of PGY0s who home matched was statistically higher when separately compared to PGY1-5s. (PGY0 vs PGY 1, 2, 3, 4, 5: 96 [30.1%] vs 63 [19.3%] P = .002, 73 [22.9%] P = .048, 50 [16.3%] P < 0.0005, 59 [19.2%] P = .002, 52 [16.9%] P < .0005). There was no statistical difference in any binary combination within PGY1 through PGY5. CONCLUSION: Nearly a third of applicants matched to their home institution for otolaryngology during the 2021 application cycle, a statistically significant increase compared to an average of the previous 5 years. While there are likely many reasons for this increase, we believe that the severely limited nature of away rotations due to the COVID-19 pandemic played a significant role in this outcome.

Comparing postoperative outcomes using electrocautery versus cold-knife de-epithelialization of dermal fat graft in parotidectomy reconstruction.

PURPOSE: The present study was developed to evaluate the effectiveness of a simple rapid technique for de-epithelializing cutaneous flaps and grafts in parotidectomy reconstruction. MATERIALS AND METHODS: 109 patients who underwent a parotidectomy with abdominal free dermal fat graft (FDFG) reconstruction between 2018 and 2021 were evaluated based on demographic factors, past medical/surgical history, type of parotidectomy performed, operative factors, and post-operative complications. These data were then stratified based on de-epithelialization technique as well as tumor malignancy status to determine any differences in complication rates or perioperative factors between electrocautery (EC) and cold knife (CK) techniques within both benign and malignant subgroups. RESULTS: 77 of the 109 participants underwent FDFG de-epithelialization using monopolar electrocautery (EC) and the remaining 32 participants underwent de-epithelialization using traditional cold knife (CK) technique. There was no statistical difference among the two groups in overall complication rate. The EC group had a significantly shorter operation time ("EC vs. CK": 144.2 min vs. 174.7 min; p = 0.031). Additionally, histopathologic samples showed that both techniques left the underlying dermis intact and without damage. CONCLUSIONS: This study demonstrated that there is no difference in complication rate or histology of FDFGs de-epithelialized using EC compared to CK. It was also shown that when controlling for confounders by looking solely at the benign subgroup of patients, EC de-epithelialization was a faster technique than CK. These findings suggest that EC is just as effective as CK, and may actually be a more efficient surgical technique to accomplish de-epithelialization of FDFG.

Cold Atmospheric Plasma as an Adjunct to Immunotherapy for Glioblastoma Multiforme.

Glioblastoma multiforme (GBM) is the most common and aggressive form of brain cancer in adults. GBM carries a dismal prognosis because of its proliferative, invasive, and angiogenic capabilities and because of its ability to downregulate the immune system. Immune-based therapies under investigation for GBM have been unsuccessful in vivo because of this downregulation. Cold atmospheric plasma (CAP) is a high-energy state of matter that can be applied directly or indirectly to tumor tissue to serve as an adjunct to immunotherapy in the treatment of GBM because it upregulates the immune system by the induction of reactive oxygen species. CAP has the potential to improve the efficacy of existing and investigative immunotherapies for GBM.
