Background:
The emergence of SARS-CoV-2 variants has raised concerns regarding their potential impact on perioperative outcomes. Its effect on patients undergoing surgery for salivary gland diseases remains unclear. This systematic review and meta-analysis aimed to evaluate the impact of the COVID-19 pandemic on salivary gland-related healthcare interventions, including cancer treatments, sialendoscopy procedures, and parotid surgery outcomes.
Materials And Methods:
Following PRISMA guidelines, a systematic search was conducted in PubMed, Embase, and Web of Science (2019-2025) for studies reporting pre- and during-COVID data. Two reviewers independently screened records, extracted data, and assessed risk of bias using the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed to pool odds ratios (ORs) for intervention outcomes.
Results:
Four studies (n=7,740 participants) were included. The pooled OR for salivary gland interventions during versus pre-COVID was 1.08 (95% CI: 0.88-1.33, P=0.45), indicating no significant change, with moderate heterogeneity (I²=46%). Subgroup analyses revealed increased odds of wound dehiscence post-parotid surgery (OR=4.40, 95% CI: 1.18-16.40) but no significant differences in delayed cancer diagnosis or urgent sialendoscopy.
Conclusion:
The COVID-19 pandemic did not significantly alter overall salivary gland intervention rates or adverse events, though some procedural complications increased non-significantly. Limited evidence underscores the need for larger, standardized studies. While this shows that surgeons maintained quality of practice in this era during the COVID-19.
