    Distribution of the head and neck surgical oncology workforce in the United States
    (Wiley, 2022-11) Talwar, Abhinav; Gordon, Alex J.; Bewley, Arnaud F.; Fancy, Tanya; Lydiatt, William M.; Weed, Donald; Moore, Michael G.; Givi, Babak; Otolaryngology -- Head and Neck Surgery, School of Medicine
    Background The recent trends in education and geographic distribution of the head and neck surgery workforce have not been studied extensively. Methods We reviewed publicly available sources to locate all fellowship-trained head and neck surgeons and recent graduates. The number of surgeons in each state was compared against head and neck cancer incidence data from the Centers for Disease Control. Results The number of graduates increased annually by 1 per 100 000 000 people from 2011–2020. The average number of fellowship-trained surgeons per state was 10 (SD: 12). The average number of new head and neck cancer cases per surgeon was 247 (SD: 135). Ten states (20%) had cases >1 SD above the national average/surgeon, while 3 (6%) had cases >1 SD below the national average. Conclusion Head and neck surgeons are located in most states, but not uniformly. Most states have approximately average density of surgeons; however, several states are outliers.

    Inhibition of tropomyosine receptor kinase B on the migration of human Schwann cell and dispersion of oral tongue squamous cell carcinoma in vitro
    (Wiley, 2019-12) Ein, Liliana; Bracho, Olena; Mei, Christine; Patel, Jaimin; Boyle, Thomas; Monje, Paula; Fernandez‐Valle, Cristina; Bas, Esperanza; Thomas, Giovana; Weed, Donald; Sargi, Zoukaa; Dinh, Christine; Neurological Surgery, School of Medicine
    Background Schwann cells (SC) may play an important role in perineural invasion (PNI) by promoting cancer cell dispersion. Brain‐derived neurotrophic factor (BDNF) may contribute to these cellular events by activating tropomyosine receptor kinase B (TrkB). This study examines the effect of TrkB inhibition on SC migration and oral cancer cell dispersion in vitro. Methods Human tongue squamous cell carcinoma (SCC‐9) and human SCs were cocultured in three different conditioned mediums: control, BDNF, and TrkB inhibitor. Cell migration, cancer cell dispersion, and SC dedifferentiation were measured on time‐lapse and immunofluorescence images. Results Cancer cell migration exceeded SC migration in all conditions. TrkB inhibition promoted SC dedifferentiation and significantly increased SC migration, when compared to BDNF conditions. TrkB inhibition also reduced cancer cell dispersion, when compared to control and BDNF‐treated cultures. Conclusion SCs may have importance in the pathophysiology of PNI. TrkB inhibition may be a potential avenue for therapeutic intervention.

    Virtual Tumor Boards for Remote Learning in Head and Neck Surgical Oncology
    (American Medical Association, 2023) Papazian, Michael R.; Chow, Michael; Weed, Donald; Liu, Jeffrey C.; Bewley, Arnaud F.; Moore, Michael G.; Givi, Babak; Otolaryngology -- Head and Neck Surgery, School of Medicine
    Importance: In addition to their patient management value, multidisciplinary tumor boards have been recognized as effective learning tools. However, the value of using a virtual tumor board as a learning tool for head and neck surgical oncology fellows has not been studied. Objective: To describe the structure and content of the American Head and Neck Society (AHNS) Virtual Tumor Board and assess its educational value as perceived by attendees. Design, setting, and participants: All sessions of the AHNS Virtual Tumor Board from April 8, 2020, to June 1, 2022, were reviewed. Topics, presenters, participants, and viewership data were collected as of October 15, 2022, from session recordings posted to an online video sharing and social media platform. Additionally, an anonymous, 14-question online survey was designed to elicit feedback from head and neck surgery trainees on virtual tumor board engagement, strengths, and weaknesses. The survey was electronically distributed in June and July 2022 to the 101 fellows enrolled in AHNS-accredited programs between July 1, 2020, and June 30, 2022. Main outcomes and measures: The primary aim was to tabulate online viewership of the sessions. The secondary aim was to qualitatively assess the experience of head and neck trainees with the AHNS Virtual Tumor Board using a survey. Results: Forty-two sessions of the virtual tumor board were held between April 8, 2020, and June 1, 2022. Almost all sessions (41 [98%]) were case based. One hundred and sixteen cases were presented, representing 2 to 3 cases per session, by 75 unique faculty members. Each session was viewed a mean of 217 times (range, 64-2216 views). In the 2021 to 2022 academic year, a mean of 60 viewers (range, 30-92 viewers) attended each live session. In all, 29 survey responses were collected from 101 fellows in AHNS-accredited programs (29% response rate). Most respondents felt the format allowed for excellent teaching (18 of 26 respondents [69%]) and discussion (19 of 26 respondents [73%]). Most respondents (22 of 29 respondents [76%]) believed that practicing head and neck surgeons would benefit from the sessions. Conclusions and relevance: This survey study found that the AHNS Virtual Tumor Board was well-attended and well-reviewed by head and neck surgical oncology trainees. The virtual tumor board format could be used as model of remote learning for other organizations.
