Pathogenesis

Etiology

Predisposing factors

General

Pathophysiology

  • Trauma/bites/neoplasia/idiopathic/iatrogenic   →   leakage of saliva into surrounding tissue.
  • Salivary gland or duct becomes damaged.
  • Saliva leaks out and takes path of least resistance.
  • Saliva irritates tissue and causes inflammation initially.
  • Granulation tissue forms the lining of the mucocele, preventing further migration of saliva.
