ABSTRACT Objective To estimate the pooled prevalence of lymphedema among adults with mucosal head and neck cancer treated with radiation therapy. Data Sources PubMed, Embase, Scopus, and Cochrane Library. Review Methods A comprehensive literature search of PubMed, Embase, Scopus, and Cochrane Library (2000–2025) identified cohort, case series, cross‐sectional, and clinical trial studies reporting lymphedema after radiotherapy for head and neck cancer. Logit‐transformed lymphedema prevalence was pooled using a DerSimonian‐Laird random‐effects model with Hartung‐Knapp‐Sidik‐Jonkman variance correction; statistical heterogeneity was evaluated using I 2 . This review was not prospectively registered. Results A total of 26 studies ( n = 3133 patients) met inclusion criteria. The pooled prevalence of lymphedema was 49% (95% CI, 36%–62%), with considerable heterogeneity (I 2 = 94%). Subgroup analyses yielded a pooled prevalence of 37% (12%–71%) for external and 45% (31%–60%) for internal lymphedema. Among studies reporting severity‐graded data, the pooled prevalence of clinically significant (grade ≥ 2) lymphedema was 32% (14%–59%). Lymphedema definitions and assessment methods varied across the included studies, most commonly employing clinical grading. Methodological quality was mixed, reflecting the predominantly retrospective, single‐arm nature of the available evidence. Overall certainty of evidence was very low. Funnel plot inspection and Egger's test suggested small‐study effects ( p = 0.06). Conclusion Lymphedema affects nearly half of patients following radiation for head and neck cancer. These findings may support routine surveillance, early identification, and timely referral for lymphedema management within survivorship care pathways. Future prospective studies should adopt standardized definitions and outcome measures to refine risk estimates and guide prevention strategies. Level of Evidence N/A.

Abstract Objectives To investigate socio-economic and clinical disparities in the utilisation of robotic surgery for head and neck cancer. Methods Using the National Cancer Database (2010–2020), 212 449 surgically treated patients were analysed. Multivariate logistic regression identified predictors of robotic versus non-robotic surgery ( p < 0.05). Results Robotic surgery utilisation increased over time during the study period. The following characteristics positively correlated with the use of robotic surgery: male, aged 41–80 years, White race, insured (with private insurance, Medicaid and Medicare) and treatment at an Academic/Research centre. Metropolitan residency, higher income/education levels, lower comorbidity (Charlson–Deyo score of 0) and Stage I disease were also associated with increased robotic surgery utilisation. Conclusion Significant socio-economic disparities exist in robotic surgery access, potentially exacerbating outcome inequities. Targeted interventions are needed to improve equity in treatment access and standardise care protocols. Further research should validate trends and address systemic barriers.

Objectives: Transoral robotic surgery (TORS) is gaining popularity and has been introduced for the treatment of Eagle syndrome. This review aims to evaluate the safety and efficacy of TORS for the treatment of Eagle syndrome. Methods: A systematic review of the English language literature using multiple databases was completed for studies describing TORS for Eagle syndrome. The quality of studies and risk of bias were evaluated using the MINORS scoring system. Results: Out of 1495 articles screened, 4 studies met criteria for inclusion in the final analysis. Across all studies, there was a 100% surgical success rate. In total, every patient had some level of symptom improvement with 84% of patients having complete symptom improvement and 16% having partial improvement. Reported estimated blood loss averaged 12.5 mL. A total of 94.7% of patients had no surgical complications and no cases were complicated by postoperative bleeding. Operative time averaged 65 minutes. The average length of stay was 2.1 days. A total of 92% of patients resumed their diet on postoperative day 1, with the remainder resuming on postoperative day 2. MINORS criteria scoring suggested moderate risk of bias in all studies. Conclusion: Based on limited quality evidence, this review suggests that TORS is a safe and effective surgical approach in the treatment of Eagle syndrome with low complication rates. Further large-scale prospective studies are warranted.
