Needle in the Haystack: Wire Bristle Foreign Body Presenting Deep Within the Tongue Base.

OBJECTIVES: To report a case of ingested wire bristle embedded within the extrinsic musculature of the tongue requiring a transcervical approach for removal and to provide a revised algorithm for the management of ingested wire bristles. METHODS: The clinical record of 1 patient who ingested a grill brush wire bristle was reviewed. A literature review was also conducted to refine a treatment algorithm for managing ingested wire bristles. RESULTS: We present a case of a 53-year-old male who accidentally ingested a grill brush wire bristle. After multiple unsuccessful endoscopic attempts at removal, the wire bristle migrated deep into the extrinsic musculature of the tongue, necessitating a transcervical approach for adequate visualization and retrieval. CONCLUSIONS: This is the first case reported of a wire bristle migrating deep into the tongue musculature that was successfully removed via a transcervical approach. Our proposed algorithm provides a comprehensive approach to the management of ingested wire bristles, specifically in cases where endoscopic retrieval is not feasible.

Flexible Versus Rigid Laryngoscopy: A Prospective, Blinded Comparison of Image Quality.

OBJECTIVE: To compare flexible distal-chip laryngoscopy (FDL) and rigid telescopic laryngoscopy (RTL) in image quality and diagnostic ability. STUDY DESIGN: Prospective cohort study; blinded comparison. METHODS: Eighteen normal adult subjects were recruited to undergo both FDL and RTL and normalized videos were recorded. Three blinded laryngologists compared the videos for color fidelity, illumination, resolution, and vascularity, and indicated superiority with FDL, RTL, or no difference. Raters also reported if an abnormality was seen and in which video it was better visualized. Videos for two subjects were repeated to assess intra-rater reliability, making 20 video comparisons across 3 raters for a total of 60 ratings. Differences in responses were analyzed via Mann-Whitney U and Pearson Χ2. Inter-rater reliability was assessed via Fleiss' kappa, and intra-rater reliability was assessed via percent agreement. RESULTS: RTL was rated superior in all categories of image quality (47 vs 5 vs 8, P < 0.01; 47 vs 7 vs 6, P < 0.01; 51 vs 5 vs 4, P<0.01; 44 vs 9 vs 7, P < 0.01, respectively). An abnormality was seen 33 times with both modalities and 6 times with RTL only. When seen with both modalities, visualization was superior in RTL compared with FDL (29 vs 4, P <0.01). CONCLUSIONS: There was significant superiority of RTL in all categories of image quality, with slight inter-rater agreement for color fidelity, resolution, and vascularity. RTL was also significantly better for visualization of abnormalities. These findings suggest superior image quality in RTL compared with FDL, but further research is required to determine if this difference is clinically significant.

Recalls of Moderate- and High-Risk Otolaryngologic Devices Approved by the US Food and Drug Administration, 2003-2019.

OBJECTIVE: The US Food and Drug Administration (FDA) regulates the marketing of medical devices based on the premarket approval (PMA) or 510(k) pathway. We investigated the relationship among the regulatory pathway of otolaryngologic devices, the number of recalls, and the recall characteristics. STUDY DESIGN: Retrospective cross-sectional analysis. SETTING: Publicly available FDA databases. METHODS: The FDA Ear, Nose, and Throat Devices Panel database was queried for 510(k) clearances and PMA approvals from 1976 to 2019. Device recalls from 2003 to 2019 were reviewed. Devices were then categorized by subspecialty, type, supporting evidence, and PMA supplement type. Logistic regression characterized the odds of recall for each device type and subspeciality. RESULTS: A total of 1061 (57.8%) 510(k) and 778 (42.3%) PMA device applications and modifications were approved. There were 120 (11.3%) recall events associated with 42 unique otolaryngologic devices cleared via the 510(k) pathway, as compared with 25 (3.2%) recall events for 5 unique PMA devices. 510(k) device approvals were more likely to be recalled than PMA device approvals (odds ratio, 3.67; 95% CI, 2.38-5.88; P < .0001). 510(k) surgical devices (odds ratio, 2.1; 95% CI, 1.1-4.4; P = .03) were more likely to be recalled than diagnostic devices. Devices designated for laryngology (70.0%) and general otolaryngology (25.0%) composed the majority of recalls. CONCLUSION: Otolaryngologic devices approved by the FDA via the 510(k) pathway exhibit a higher number of recalls than the PMA pathway. Given the balance between regulation and facilitating innovation, postmarket surveillance and ongoing regulatory improvements are critical to ensure optimal safety of medical devices.

A Novel Approach to Vocal Fold Mucous Retention Cysts: Awake KTP Laser-Assisted Marsupialization.

Vocal fold mucous retention cysts are an important etiology of dysphonia and have classically been treated via microsurgical excision under general anesthesia. We present four cases that were treated with a novel technique of awake potassium-titanyl-phosphate laser-assisted marsupialization under local anesthesia. Reasons for in-office treatment included older age, medical comorbidities, and desire to avoid surgery/general anesthesia. No recurrences were observed and all patients had improved vocal quality, with a mean reduction in Voice Handicap Index-10 of 12.5. Hence, awake potassium-titanyl-phosphate laser treatment exhibits potential as a modality for addressing vocal fold mucous retention cysts in select patients with favorable outcomes.

Idiopathic Ulcerative Laryngitis: A National Survey of Academic Laryngologists.

OBJECTIVES: Idiopathic ulcerative laryngitis (IUL) is a rare disorder characterized by ulceration in the mid-membranous portions of the vocal folds. The etiology and optimal management of this condition are poorly understood. We aimed to survey laryngologists on their experiences with managing IUL in order to better understand the diagnosis and treatment of this unusual condition. METHODS: An online survey was sent to 149 laryngologists practicing at academic institutions in the United States. Survey questions assessed respondents' professional backgrounds and clinical experiences with IUL. Individual responses were tallied and calculated as percentages of total responses. RESULTS: A total of 96 out of 149 academic laryngologists completed the survey, leading to an overall response rate of 64.4%. All respondents reported that they had encountered IUL in practice, including 56.3% who reported having seen 1-10 cases, 22.9% reporting 11-20 cases, and 20.8% reporting greater than 20 cases over their careers. Dysphonia (99.0%) and cough (84.4%) were the two co-occurring primary presenting symptoms reported. Most base diagnosis on laryngeal videostroboscopy (93.8%). Fungal/bacterial cultures and operative biopsy had been performed by approximately 30% of respondents with occasional candidiasis reported but otherwise negative or nonspecific results. Common therapies used were empiric: antireflux therapy (91.7%), modified voice rest (91.7%), and oral steroids (80.2%). Among survey respondents with experience managing more than 10 cases of IUL, many found complete voice rest (60.0%), oral steroids (55.9%), behavioral cough suppression (46.7%), and modified voice rest (46.3%) to be at least moderately effective treatment options. Resolution of symptoms was most commonly reported to occur over the course of 1-3 months (59.4%) and recurrences were seen not very often or never (85.4%). However, permanent sequelae were common, including vocal fold stiffness (89.6%) and dysphonia (81.3%). CONCLUSIONS: IUL is a rare disorder of unknown etiology. Diagnosis is typically made with laryngeal videostroboscopy and spontaneous resolution occurs over 1-3 months. Laryngologists commonly treat empirically with antireflux therapy, voice rest, antimicrobials, and oral steroids. While no empiric treatment appears to be highly effective for the management of IUL, complete or modified voice rest, oral steroids, and behavioral cough suppression may be the most effective of the currently available options. Further research is necessary to improve the understanding and optimal management of IUL.

Flexible versus rigid laryngoscopy: A randomized crossover study comparing patient experience.

OBJECTIVES: To compare flexible distal-chip laryngoscopy (FDL) versus rigid telescopic laryngoscopy (RTL) in regard to examinees' pain level, comfort, satisfaction, and preference, and to evaluate the clinician's assessment of the examinees' experience with both exam types. STUDY DESIGN: Randomized crossover study. METHODS: Twenty-three normal adult subjects were recruited to undergo both FDL and RTL; the initial exam type was randomized. Subjects and clinicians completed corresponding questionnaires after each exam. Differences in participant characteristics and questionnaire scores between the two exam types were assessed via Pearson χ2 and paired t tests, respectively. RESULTS: Overall, participants reported that FDL was more uncomfortable than RTL (4.22 vs. 2.91, P = .003) and scored higher on the pain scale for FDL compared to RTL (2.91 vs. 1.70, P = .006). However, there was no significant difference in number of participants who preferred FDL versus RTL (10 [43%] vs. 13 [57%]). Poor correlation was seen between clinicians' assessment of participants' discomfort and actual reported discomfort for FDL (2.70 vs. 4.22, P = .001). CONCLUSIONS: Subjects undergoing FDL experience greater discomfort and pain compared to RTL, but do not demonstrate a differential preference of exam. Overall, clinicians underestimate the discomfort of patients undergoing FDL, but participants maintain high satisfaction with both exams nonetheless.
