Abstract

Insights

Minor salivary gland biopsies are safe, with an 11% complication rate. While postsurgical issues can occur, permanent problems are rare, especially with lower lip procedures.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Pathology
  • Otolaryngology

Background:

  • Salivary gland biopsies are crucial for diagnosing various conditions.
  • Understanding complication rates is essential for patient counseling and procedural refinement.

Purpose of the Study:

  • To systematically review and meta-analyze complications following major and minor salivary gland biopsy.
  • To determine the overall and neurological complication prevalence after these procedures.

Main Methods:

  • Systematic review and meta-analysis of observational studies.
  • Searched Medline/PubMed, EMBASE, Cinahl, LILACS, and Scopus.
  • Included 27 studies with 3208 patients; analyzed using R software.

Main Results:

  • The combined prevalence of postsurgical complications was 11% (95% CI, 8-13%).
  • Neurological complications occurred in 3% of cases (95% CI, 1-6%).
  • Surgical technique did not significantly impact overall or neurological complication rates.

Conclusions:

  • Minor salivary gland biopsies, particularly on the lower lip, are safe and predictable.
  • Postoperative complications are more frequent than previously thought, but permanent sequelae are uncommon.
