Item Denosumab Treatment for a Residual Giant Cell Tumor of the Clivus: A Case Report and Review of the Literature(Elsevier, 2018-10) Huh, Andrew; Villelli, Nicolas; Martinez, Daniel; Ting, Jonathan; Payner, Troy D.; Kulwin, Charles G.; Neurological Surgery, School of MedicineBackground Giant cell tumors (GCTs) are a locally aggressive primary bone neoplasm of osteoclast-like cells. These lesions largely occur in the epiphyses of long bones, but there have been rare reports of occurrence in the pelvis, spine, or skull. Of those located in the skull, involvement of the clivus has been rarely reported. Case Description We present a case of an 18-year-old woman presenting with a third nerve palsy, found to have a lytic lesion of the upper clivus that was primarily treated with endoscopic endonasal resection. Her third nerve palsy resolved postoperatively, and subsequent histopathologic analysis revealed a GCT. Six-month postoperative magnetic resonance imaging (MRI) revealed progression of residual disease for which she was treated with adjuvant denosumab. This treatment resulted in a significant decrease in the tumor size. She subsequently underwent proton beam radiation. At 1-year postsurgery, the patient's MRI remained stable after completing denosumab and proton therapy. She was neurologically intact and had no issues from her treatment. Conclusions Denosumab has demonstrated anti-GCT efficacy. In combination with proton therapy, it has the potential to spare a young, vulnerable population from adverse long-term effects of traditional adjuvant radiation therapy. To our knowledge, this is the first report of the use of denosumab in the treatment of GCT of the clivus in the United States.Item Facing Facts: Facial Injuries from Stand-up Electric Scooters(ACOG, 2020-01-15) Alwani, Mohamedkazim; Jones, Alexander J.; Sandelski, Morgan; Bandali, Elhaam; Lancaster, Benjamin; Sim, Michael W.; Shipchandler, Taha; Ting, Jonathan; Otolaryngology -- Head and Neck Surgery, School of MedicineBackground Stand-up electric scooters (SES) are a popular public transportation method. Numerous safety concerns have arisen since their recent introduction. Methods A retrospective chart review was performed to identify patients presenting to the emergency departments in Indianapolis, who sustained SES-related injuries. Results A total of 89 patients were included in our study. The average patient age was 29 ± 12.9 years in a predominantly male cohort (65.2%). No patient was documented as wearing a helmet during the event of injury. Alcohol intoxication was noted in 14.6% of accidents. Falling constituted the leading trauma mechanism (46.1%). Injuries were most common on Saturday (24.7%) from 14h00 to 21h59 (55.1%). Injury types included: abrasions/contusions (33.7%), fractures (31.5%), lacerations (27.0%), or joint injuries (18.0%). The head and neck region (H&N) was the most frequently affected site (42.7%). Operative management under general anesthesia was necessary for 13.5% of injuries. Nonoperative management primarily included conservative orthopedic care (34.8%), pain management with nonsteroidal anti-inflammatory drugs (NSAIDs) (34.8%) and/or opioids (4.5%), bedside laceration repairs (27.0%), and wound dressing (10.1%). Individuals sustaining head and neck injuries were more likely to be older (33.8 vs. 25.7 years, p=0.003), intoxicated by alcohol (29.0% vs. 3.9%, p=0.002), and requiring CT imaging (60.5% vs. 9.8%, p <0.001). Conclusion Although SESs provide a convenient transportation modality, unregulated use raises significant safety concerns. More data need to be collected to guide future safety regulations.Item Factors Affecting Speech Discrimination in Children with Cochlear Implants: Evidence from Early-Implanted Infants(American Academy of Audiology, 2016-06) Phan, Jennifer; Houston, Derek M.; Ruffin, Chad; Ting, Jonathan; Holt, Rachael Frush; Otolaryngology -- Head and Neck Surgery, School of MedicineBackground To learn words and acquire language, children must be able to discriminate and correctly perceive phonemes. Although there has been much research on the general language outcomes of children with cochlear implants (CIs), little is known about the development of speech perception with regard to specific speech processes, such as speech discrimination. Purpose The purpose of this study was to investigate the development of speech discrimination in infants with CIs and identify factors that might correlate with speech discrimination skills. Research Design Using a Hybrid Visual Habituation procedure, we tested infants with CIs on their ability to discriminate the vowel contrast /i/-/u/. We also gathered demographic and audiological information about each infant. Study Sample Children who had received CIs before 2 yr of age served as participants. We tested the children at two post cochlear implantation intervals: 2–4 weeks post CI stimulation (N = 17) and 6–9 mo post CI stimulation (N = 10). Data Collection and Analysis The infants’ mean looking times during the novel versus old trials of the experiment were measured. A linear regression model was used to evaluate the relationship between the normalized looking time difference and the following variables: chronological age, age at CI stimulation, gender, communication mode, and best unaided pure-tone average. Results We found that the best unaided pure-tone average predicted speech discrimination at the early interval. In contrast to some previous speech perception studies that included children implanted before 3 yr of age, age at CI stimulation did not predict speech discrimination performance. Conclusions The results suggest that residual acoustic hearing before implantation might facilitate speech discrimination during the early period post cochlear implantation; with more hearing experience, communication mode might have a greater influence on the ability to discriminate speech. This and other studies on age at cochlear implantation suggest that earlier implantation might not have as large an effect on speech perception as it does on other language skills.Item Low Misrepresentation Rates of Scholarly Work in Otolaryngology-Head and Neck Surgery Residency Applications(Cureus, 2020-02) Alwani, Mohamedkazim; Sandelski, Morgan; Van Buren, Lauren; Bandali, Elhaam; Ting, Jonathan; Shipchandler, Taha; Illing, Elisa A.; Otolaryngology -- Head and Neck Surgery, School of MedicineObjectives To evaluate research trends, including rates of misrepresentation of scholarly work, in otolaryngology residency applications received by a single institution during the 2018-2019 residency application cycle. Methods After obtaining Institutional Review Board approval, all residency applications to the Department of Otolaryngology-Head and Neck Surgery at Indiana University School of Medicine, Indianapolis, IN for the 2018-2019 cycle were de-identified and analyzed. Demographic and research information including the number of listed peer-reviewed articles/abstracts, types of research projects, and misrepresentations were retrospectively evaluated. Results Our institution received 321 applications, which represented 69.5% of the entire 2018-2019 otolaryngology applicant pool. The average United States Medical Licensing Examination (USMLE) Step 1 score was 246 ±12.4. There were 203 (62.2%) applicants who reported 591 published citations with 20 (6.2%) applicants misrepresenting 26 items (4.4%). Applicants who misrepresented research output had lower average Step 1 scores (237.4 vs 246.4, p: <0.05). Self-promotion to higher authorship status was the most common form of misrepresentation (61.5%). Conclusions The role of scholarly work in stratifying applicants continues to expand. Although a competitive application climate motivates a minority of applicants to misrepresent scholarly work, rates of misrepresentation in otolaryngology applications are low and continue to decline. The level of evidence assigned to this study is III.Item Simulation of laryngotracheal reconstruction with 3D-printed models and porcine cadaveric models(Wiley, 2022-08-09) Falls, Megan; Vincze, Jonathan; Brown, Joshua; Witsberger, Chelsey; Discolo, Christopher; Partain, Matthew; Rosen, Philip; Ting, Jonathan; Zopf, David; Otolaryngology -- Head and Neck Surgery, School of MedicineObjectives: Laryngotracheal reconstruction (LTR) is a complex operation used to treat subglottic stenosis. The use of simulator models is a valuable tool in surgical trainee education, particularly for operations such as LTR that are less common outside high-volume centers. Three-dimensional (3D) printing of the human airway may provide an effective and more accessible alternative to porcine cadaveric models. The objective of this study is to compare the educational value of a 3D-printed model and a porcine cadaveric model as LTR simulation methods. Methods: Simulated LTR procedures were completed by 12 otolaryngology residents and a faculty physician on the cadaveric model and the 3D-printed simulator model. Both models were evaluated by fellowship-trained pediatric otolaryngologists to establish construct validity. Pre-procedure surveys of participants evaluated confidence and attitude toward models and post-procedure surveys evaluated confidence, overall impressions, relevance, content validity, and face validity. Results: Participants reported a similar mean increase in confidence after performing LTR on the 3D-printed model (14%) and cadaveric model (11%). Participants rated both models similarly for utility as an overall training tool and in teaching surgical planning and improving operative techniques. However, participants found the 3D-printed model more useful for teaching anatomy (p = .047). Conclusion: 3D-printed models have practical benefits over cadaveric models; they do not decompose and can be custom made to model a disease state such as subglottic stenosis. Participants reported a similar mean increase in confidence after using either simulation. The 3D-printed model is a promising simulation candidate as it compares well to an animal model and has the advantage of being more anatomically true to pediatric patients.Item Sinonasal Chondromyxoid Fibroma: Case Report and Literature Review(Cureus, 2019-10-05) El-Kouri, Nadeem; Elghouche, Alhasan; Chen, Shaoxiong; Shipchandler, Taha; Ting, Jonathan; Pathology and Laboratory Medicine, School of MedicineChondromyxoid fibroma (CMF) is a rare, benign neoplasm of the chondroid, myxoid, and fibrous tissue. It characteristically affects the lower extremity long bones, although it may rarely arise within the craniofacial skeleton. We report the diagnosis and management of a 31-year-old male with a large, incidentally discovered CMF originating from the sphenoid sinus. A subsequent review of the literature reveals the need to differentiate from more aggressive neoplasms, such as chondrosarcoma and chondroma, which share radiographic features. A histopathologic examination is crucial for proper diagnosis and treatment. We discuss clinical sequelae, highlight the importance of a thorough pre-operative evaluation, and summarize previously suggested treatment paradigms.Item A Systematic Review of Sellar and Parasellar Brown Tumors: An Analysis of Clinical, Diagnostic, and Management Profiles(Elsevier, 2019-12) Alwani, Mohamedkazim M.; Monaco, Gina N.; Harmon, Sydney M.; Nwosu, Obi I.; Vortmeyer, Alexander O.; Payner, Troy D.; Ting, Jonathan; Otolaryngology -- Head and Neck Surgery, School of MedicineObjective To systematically review and analyze clinical, diagnostic, and management trends in sellar and parasellar brown tumors reported in existing literature. Methods In this systematic review, PubMed, Ovid MEDLINE, Scopus, and Google Scholar databases were searched for reported cases of sellar/parasellar brown tumors. Relevant titles and abstracts were screened in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. Articles meeting inclusion criteria were subjected to data extraction, summarization, and analysis. A rare case of parasellar brown tumor was also presented. Results Eight reports (including the current report) were eligible for inclusion. Mean patient age was 42.75 years. Reported symptoms included visual disturbances (n = 6), headache (n = 5), fatigue (n = 3), nausea/vomiting (n = 2), chest pain (n = 1), neck pain (n = 1), and dysphagia (n = 1). In cases where computed tomography findings were provided (n = 6), lesions were noted to be expansile and lytic. Lesions were hyperintense on T2-weighted magnetic resonance imaging (66.7%) and demonstrated contrast enhancement (83.3%). Histology unanimously showed multinucleated giant cells in a fibrovascular connective tissue stroma. Dramatic symptom resolution was noted in all patients who underwent resection of the sellar/parasellar brown tumor (n = 4; 50%). Conclusions Sellar/parasellar brown tumors are a rare, tertiary manifestation of hyperparathyroidism and can be elusive to diagnose. Diagnosis requires a high index of clinical suspicion in addition to comprehensive biochemical testing, imaging, and histopathologic analysis. Surgical extirpation is favored in cases where the lesion is causing compressive symptoms, or if it is unresponsive to management of hyperparathyroidism.Item Telemedicine in Otolaryngology During COVID-19: An Exploratory Assessment of Provider and Patient Attitudes(Sage, 2023) Alwani, Mohamedkazim; Campiti, Vincent; Nesemeier, Ryan; Vernon, Dominic; Shipchandler, Taha; Ting, Jonathan; Parker, Noah; Otolaryngology -- Head and Neck Surgery, School of MedicineObjective: To determine provider and patient attitudes toward telemedicine in Otolaryngology-Head and Neck Surgery (OHNS). Methods: Otolaryngology practitioners conducting outpatient clinics at an academic tertiary referral center were provided with a pre-Study Provider Perception Questionnaire (pre-PPQ) designed to evaluate pre-study perception of telemedicine in otolaryngology. A post-study Provider Perception Questionnaire (post-PPQ) designed to evaluate elements similar to those constituting the PrePPQ was completed at 6 weeks. Additionally, following each visit, providers and patients completed Individual Encounter Survey Questionnaires (IESQ) to evaluate the virtual clinical encounter experience. Results: The pre-PPQ was completed by 29 providers, while the post-PPQ was completed by 12 providers. A total of 236 post-visit provider IESQs were completed, of which 208 were deemed successful. Audio/visual (AV) difficulties and limited server connectivity for the patient were most common causes for unsuccessful encounters. Providers reported that the most appropriate use of telemedicine, on both pre-PPQ and post-PPQ, was triaging patients to determine the need for in-person visits. The inability to perform a physical exam was rated as the primary barrier to telemedicine in OHNS on both pre-PPQ and post-PPQ. Patients strongly agreed with the statements, "My healthcare provider was able to understand my healthcare condition" and, "I felt comfortable communicating with my healthcare provider" 92.0% and 95.4% of the time, respectively. Conclusion: Both providers and patients demonstrated an overall positive attitude toward the use of telemedicine in the provision of otolaryngologic care.Item YouTube Videos Demonstrating the Nasopharyngeal Swab Technique for SARS-CoV-2 Specimen Collection: Content Analysis(JMIR, 2021-01) Itamura, Kyohei; Wu, Arthur; Illing, Elisa; Ting, Jonathan; Higgins, Thomas; Otolaryngology -- Head and Neck Surgery, School of MedicineBackground: Real-time polymerase chain reaction using nasopharyngeal swabs is currently the most widely used diagnostic test for SARS-CoV-2 detection. However, false negatives and the sensitivity of this mode of testing have posed challenges in the accurate estimation of the prevalence of SARS-CoV-2 infection rates. Objective: The purpose of this study was to evaluate whether technical and, therefore, correctable errors were being made with regard to nasopharyngeal swab procedures. Methods: We searched a web-based video database (YouTube) for videos demonstrating SARS-CoV-2 nasopharyngeal swab tests, posted from January 1 to May 15, 2020. Videos were rated by 3 blinded rhinologists for accuracy of swab angle and depth. The overall score for swab angle and swab depth for each nasopharyngeal swab demonstration video was determined based on the majority score with agreement between at least 2 of the 3 reviewers. We then comparatively evaluated video data collected from YouTube videos demonstrating the correct nasopharyngeal swab technique with data from videos demonstrating an incorrect nasopharyngeal swab technique. Multiple linear regression analysis with statistical significance set at P=.05 was performed to determine video data variables associated with the correct nasopharyngeal swab technique. Results: In all, 126 videos met the study inclusion and exclusion criteria. Of these, 52.3% (66/126) of all videos demonstrated the correct swab angle, and 46% (58/126) of the videos demonstrated an appropriate swab depth. Moreover, 45.2% (57/126) of the videos demonstrated both correct nasopharyngeal swab angle and appropriate depth, whereas 46.8% (59/126) of the videos demonstrated both incorrect nasopharyngeal swab angle and inappropriate depth. Videos with correct nasopharyngeal swab technique were associated with the swab operators identifying themselves as a medical professional or as an Ear, Nose, Throat–related medical professional. We also found an association between correct nasopharyngeal swab techniques and recency of video publication date (relative to May 15, 2020). Conclusions: Our findings show that over half of the videos documenting the nasopharyngeal swab test showed an incorrect technique, which could elevate false-negative test rates. Therefore, greater attention needs to be provided toward educating frontline health care workers who routinely perform nasopharyngeal swab procedures.
