Senior Mentorship and Scholarly Success: Assessing Influences on Successful Neurosurgery Residency Applicant's H-index.

BACKGROUND: Research productivity is on the rise as neurosurgical residency positions become increasingly competitive. OBJECTIVE: We explored the relationship between neurosurgical residency applicant's senior author's research productivity and matching into a neurosurgery residency program. METHODS: A retrospective analysis of bibliometric data for applicants who matched into neurosurgery in 2022-2023 and their senior authors was conducted using Scopus. RESULTS: Logistic regression revealed a significant association between h-index values and top 40 match outcomes (p=0.038). The maximum h-index of senior authors significantly predicted matches at top 40 programs (p=0.003). Affiliation with a top 40 medical school increased both applicant and senior author h-indices (p=0.05, p<0.001 respectively). Linear regression of the maximum h-index of senior authors in pre-residency publications explained 42% of this variability (p<0.001). A multiple linear regression model incorporating this with publication number elucidated 69% of the variance in interns' h-index. Authorship data categorized as first, second, and third author positions showed 1847 first author, 1417 second author, and 118 third author publications over two-years. Applicants at top 40 residency programs had more first and second author publications compared to those from non-top 40 programs (p=0.0158, p=0.0275). CONCLUSION: There is a strong correlation between a neurosurgical applicant's academic output and that of their senior authors. The number of publications and the maximum h-index of senior authors significantly predict applicant h-indices. We also demonstrated that there is a significant difference in the academic productivity of applicants and senior authors of applicants who successfully match into a top 40 i(h)5 rated neurosurgical residency.

Supraorbital keyhole approaches in the first 3 years of practice: outcomes and lessons learned. Patient series.

BACKGROUND: Supraorbital keyhole approaches (SKAs) have garnered criticism for a limited surgical exposure, restrictive surgical freedom, blind spots, and the learning curve. This retrospective study of patients who underwent SKA aims to explore the outcomes, technical nuances, and the learning curve reflected in a single surgeon's experience in the initial 3 years of practice. OBSERVATIONS: A total of 20 SKA operations were performed in 19 patients. Gross- or near-total resection was achieved in 14 of 17 tumor cases. The mean blood loss was 80.5 mL, the mean duration of surgery was 5 hours, and the median stay was 3 days. Endoscopic augmentation was used in 11 cases in which additional tumor removal occurred in 8 of the 11 cases. There were no cases of cerebrospinal fluid leakage or wound infection. A 30-day readmission and typical narcotics after discharge were seen in one patient each. When comparing two halves of a neurosurgery practice over 3 years, the duration of surgery was significantly longer in the later year, which is likely due to operating on a larger tumor size as the years progressed. No cases required static retractors or conversion to larger craniotomies. LESSONS: Careful case selection and respecting the learning curve allows the safe incorporation of SKA in the early stages of neurosurgical practice.
