Neurotology Workforce in the United States: Gender Diversity and Geographic Distribution

OBJECTIVE

The workforce of neurotology has changed with increasing numbers of accredited programs and diverse representation among trainees over the past several decades. This study aims to describe the characteristics, density, and geographic variation of the current neurotology workforce in the United States.

STUDY DESIGN

Cross-sectional study.

SETTING

American Board of Otolaryngology-Head and Neck Surgery portal and online search.

METHODS

The study cohort included physicians certified in Neurotology by the American Board of Otolaryngology as of 2021 (n = 372). Physician characteristics including years of practice, gender, practice setting, and location were collected. Geographic variation analysis was performed by the state, county, and hospital referral region. Associations between the number of neurotologists per population and socioeconomic characteristics were assessed using multivariable regression analysis.

RESULTS

Among 372 neurotologists, 65% practiced in academic settings and 13% were female. The percentage of female neurotologists increased from 0% among neurotologists with ≥30 years of practice to 23% among <10 years of practice. There were no differences in a practice setting by gender. The geographical analysis demonstrated that the average number of neurotologists was 1.1 per 1 million Americans. In a multivariable model, the density of neurotologists was significantly higher within counties with the highest quartiles of college education (β = .6 [95% confidence interval, CI: 0.3-0.8]) and income (β = .3 [95% CI: 0.1-0.6]).

CONCLUSION

The number of board-certified neurotologists has gradually increased and there have been trends toward greater gender diversity. The geographical distribution of neurotology practice was concentrated in counties with higher socioeconomic status as expected given the referral-based nature of the subspecialty. There should be efforts to reach out to low socioeconomic communities to ensure equivalent access to neurotological care.

Systematic Review: The Neovaginal Microbiome

OBJECTIVE

To review neovaginal colonization and inflammatory patterns, and factors that may impact this.

METHODS

A systematic review of the neovaginal microbiome was conducted in concordance with PRISMA guidelines through October 2021.

RESULTS

Thirteen articles were included, totaling 458 patients. Neovaginal constructions were most commonly performed with penile and scrotal skin grafts, sigmoid segments, and peritoneal grafts. The neovaginal microflora identified were generally polymicrobial and shared similarities with the native tissue. Nine studies identified Lactobacillus: 5/6 for penile skin, 1/3 for sigmoid, 1/1 for peritoneum, and 2/3 for other graft types, suggesting that the neovagina may support Lactobacillus either innately, via rectal migration or oral probiotic supplementation. A polymicrobial, bacterial vaginosis-like environment was found in nine studies. Inflammatory markers were also described: 2/6 for penile skin, 2/3 for sigmoid, 0/1 for peritoneum, and 1/3 for other graft types. Scant data were available on the impact of postsurgical duration, oral hormones, dilating, sexual practices, or douching on the neovaginal microbiome.

CONCLUSION

Understanding and optimizing the polymicrobial neovaginal microenvironment may improve surgical outcomes, specifically inflammatory, pain, and infectious. Future research should focus on standardizing testing and classification systems, and treating neovaginal dysbiosis.
