Adverse Events Associated With Image-Guided Sinus Navigation in Endoscopic Sinus Surgery: A MAUDE Database Analysis

Functional Endoscopic Sinus Surgery: Key Points for Safer Surgery

Objectives: To review measures for safer functional endoscopic sinus surgery (FESS). Methods: PubMed, EBSCO, UpToDate, Proquest Central at Kırıkkale University, Google, and Google Scholar were used in the literature review. The search was performed using keywords of "functional endoscopic sinus surgery," "FESS," "Safety," "Image-Guided," and "complications" between 2000 and 2024. Results: Inflammatory and infectious sinus illnesses are the most prevalent indications for FESS. The 4 most common methods for FESS are endoscopic uncinectomy, maxillary antral ostomy/ethmoidectomy, anterior ethmoidectomy, and posterior ethmoidectomy. FESS has a complication rate of 0% to 1.5% for significant problems and 1.12% to 20.8% for minor issues. Sinus surgery outcomes can be improved and problems avoided with careful preoperative preparation. Powered instrumentation may enhance the severity of the problems rather than the number of occurrences. Intraoperative detection of cerebrospinal fluid leakage necessitates immediate localization and fixing of the leaking structure. The danger of infection increases and hospital stays are longer when investigation is delayed. In image-guided surgery, surgeons employ preoperative imaging data to pinpoint the exact position of a surgical tool concerning surrounding anatomical structures in real time. Although initially designed for use in neurosurgery, endoscopic sinus surgery has quickly become one of the most popular applications of this technique. Conclusion: Safer FESS can be accomplished with accurate CT scans, good patient preparation, surgical knowledge and training, and by using image guidance for endoscopic sinus surgery.

Assessing the Reproducibility of Research Based on the Food and Drug Administration Manufacturer and User Facility Device Experience Data

OBJECTIVE

This article aims to assess the reproducibility of Manufacturer and User Facility Device Experience (MAUDE) data-driven studies by analyzing the data queries used in their research processes.

METHODS

Studies using MAUDE data were sourced from PubMed by searching for "MAUDE" or "Manufacturer and User Facility Device Experience" in titles or abstracts. We manually chose articles with executable queries. The reproducibility of each query was assessed by replicating it in the MAUDE Application Programming Interface. The reproducibility of a query is determined by a reproducibility coefficient that ranges from 0.95 to 1.05. This coefficient is calculated by comparing the number of medical device reports (MDRs) returned by the reproduced queries to the number of reported MDRs in the original studies. We also computed the reproducibility ratio, which is the fraction of reproducible queries in subgroups divided by the query complexity, the device category, and the presence of a data processing flow.

RESULTS

As of August 8, 2022, we identified 523 articles from which 336 contained queries, and 60 of these were executable. Among these, 14 queries were reproducible. Queries using a single field like product code, product class, or brand name showed higher reproducibility (50%, 33.3%, 31.3%) compared with other fields (8.3%, P = 0.037). Single-category device queries exhibited a higher reproducibility ratio than multicategory ones, but without statistical significance (27.1% versus 8.3%, P = 0.321). Studies including a data processing flow had a higher reproducibility ratio than those without, although this difference was not statistically significant (42.9% versus 17.4%, P = 0.107).

CONCLUSIONS

Our findings indicate that the reproducibility of queries in MAUDE data-driven studies is limited. Enhancing this requires the development of more effective MAUDE data query strategies and improved application programming interfaces.

Comparing adverse events associated with LigaSure and Harmonic devices in head and neck surgery

OBJECTIVE

To characterize adverse events, provide a safety profile, and understand patient outcomes after complications arising from LigaSure and Harmonic use in the head and neck region.

METHODS

Retrospective analysis of adverse events from the Manufacturer and User Facility Device Experience (MAUDE) between January 2013 and 2023.

RESULTS

A total of 158 LigaSure and 159 Harmonic events were extracted. There were significantly more reports of Harmonic device overheating (6.9% vs. 0.6%, p = 0.003) and spontaneous self-activation (4.4% vs. 0%, p = 0.032). Although intra-operative and post-operative complications were similar among both groups, there were significantly more intra-operative bleeding events for LigaSure as compared to Harmonic (8.2% vs. 0.0%, p = 0.001).

CONCLUSION

Understanding technical complications and adverse events attributable to LigaSure and Harmonic devices enables the development of clinically relevant risk mitigation strategies. Surgeons should avoid improper use by remaining vigilant of device functionality and temperature changes.
