However, there is limited data on adverse events associated with or caused by the use of rhinolaryngoscopes.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n In this study, we used the Manufacturer and User Facility Device Experience (MAUDE) database with the aim of providing insights that may assist otolaryngologists in better understanding the limitations of these devices and selecting appropriate procedures for their specific clinical setting.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We characterized complications associated with the postmarket use of rhinolaryngoscope devices from the US Food and Drug Administration MAUDE database from 2016 through 2023.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A total of 2591 reports were identified, including 2534 device malfunctions, 56 injuries, and 1 death, from 2016 through 2023. The most common device problem with rhinolaryngoscopes was breakage (n=1058 reports, 40.8%), followed by fluid leaks (n=632 reports, 24.4%). The third most common problem was poor image quality (n=467 reports, 18%). Other device issues included contamination or device reprocessing problems (n=127 reports, 4.9%), material deformation or wear (n=125 reports, 4.8%), and device detachment (n=73 reports, 2.8%). Of the 63 reported adverse events, the most common patient-related adverse event was hemorrhage or bleeding, accounting for 18 reports, with the root causes including material deformation or wear, breakage, wrinkled rubber, or improper operation.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Our study offers valuable insights for endoscopists and manufacturers to recognize potential issues and adverse events associated with the use of rhinolaryngoscopes. It emphasizes the need for improving device reliability, training, and procedural protocols to enhance patient safety during diagnostic procedures.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/67036","type":"journal-article","created":{"date-parts":[[2025,2,6]],"date-time":"2025-02-06T05:10:16Z","timestamp":1738818616000},"page":"e67036-e67036","source":"Crossref","is-referenced-by-count":0,"title":["Device Failures and Adverse Events Associated With Rhinolaryngoscopes: Analysis of the Manufacturer and User Facility Device Experience (MAUDE) Database"],"prefix":"10.2196","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4136-7928","authenticated-orcid":false,"given":"Shao-Hsuan","family":"Chang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6143-5732","authenticated-orcid":false,"given":"Daishi","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0807-0217","authenticated-orcid":false,"given":"Chi-Sheng","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0129-4867","authenticated-orcid":false,"given":"Dong","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1925-2059","authenticated-orcid":false,"given":"Lung-Kun","family":"Yeh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2025,2,5]]},"reference":[{"issue":"10","key":"R1","doi-asserted-by":"publisher","first-page":"1024","DOI":"10.1017\/S0022215108002533","article-title":"Nasal and instrument preparation prior to rigid and flexible nasendoscopy: a systematic review","volume":"122","author":"Nankivell","journal-title":"J Laryngol Otol"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.1002\/lary.20712","article-title":"Advances in office-based diagnosis and treatment in laryngology","volume":"119 Suppl 2","author":"Rosen","journal-title":"Laryngoscope"},{"issue":"10","key":"R3","doi-asserted-by":"publisher","first-page":"882","DOI":"10.1001\/jamaoto.2015.1740","article-title":"Assessment of vibratory characteristics in children following airway reconstruction using flexible and rigid endoscopy and stroboscopy","volume":"141","author":"Zacharias","journal-title":"JAMA Otolaryngol Head Neck Surg"},{"issue":"10","key":"R4","doi-asserted-by":"publisher","first-page":"3399","DOI":"10.4103\/jfmpc.jfmpc_489_19","article-title":"Flexible nasopharyngolaryngoscopy: evaluation and appraisal of its effectiveness and diagnostic yield, the Nigerian experience","volume":"8","author":"Aremu","journal-title":"J Family Med Prim Care"},{"issue":"12","key":"R5","doi-asserted-by":"publisher","first-page":"2016","DOI":"10.1097\/00005537-200012000-00007","article-title":"The role of fiberoptic nasopharyngoscopy in the management of the acute airway in angioneurotic edema","volume":"110","author":"Bentsianov","journal-title":"Laryngoscope"},{"issue":"8","key":"R6","doi-asserted-by":"publisher","first-page":"3147","DOI":"10.1007\/s00405-017-4600-1","article-title":"Comparison of long-term voice outcomes after vocal fold augmentation using autologous fat injection by direct microlaryngoscopy versus office-based calcium hydroxylapatite injection","volume":"274","author":"Zelen\u00edk","journal-title":"Eur Arch Otorhinolaryngol"},{"issue":"12","key":"R7","doi-asserted-by":"publisher","first-page":"2256","DOI":"10.1097\/01.mlg.0000184325.44968.b1","article-title":"Prevalence of laryngeal irritation signs associated with reflux in asymptomatic volunteers: impact of endoscopic technique (rigid vs. flexible laryngoscope)","volume":"115","author":"Milstein","journal-title":"Laryngoscope"},{"issue":"6","key":"R8","doi-asserted-by":"publisher","first-page":"772","DOI":"10.1016\/j.jvoice.2011.11.009","article-title":"Evaluation of dysphonic patients by general otolaryngologists","volume":"26","author":"Cohen","journal-title":"J Voice"},{"issue":"8","key":"R9","doi-asserted-by":"publisher","first-page":"709","DOI":"10.1111\/j.1365-2044.1995.tb06100.x","article-title":"A fibreoptic laryngoscope for paediatric anaesthesia.
