Stafne Bone Cyst: Symptoms and Treatment

Written by Medicover Team and Medically Reviewed by Dr Vutala Prathyusha , Dentists



Stafne Bone Cyst, also known as static bone cavity or lingual mandibular salivary gland depression, is a rare, noncancerous condition that affects the jawbone. It is characterized by a cavity or hollow space that forms near the lower back part of the jaw.

This cyst does not typically cause any symptoms or health issues, and it is often discovered incidentally during dental X-rays or examinations. Stafne Bone Cyst is considered a benign and harmless condition that generally does not require any treatment unless it causes complications or affects surrounding structures.


What are the Types of Stafne Bone Cyst?

Stafne Bone Cysts typically manifest in distinct forms, each presenting unique characteristics and locations within the oral cavity.

  • Submandibular Gland Depression (Submandibular Gland Lobe): A Stafne bone cyst located below the mandible near the submandibular gland.
  • Sublingual Gland Depression (Sublingual Gland Lobe): A Stafne bone cyst located below the mandible near the sublingual gland.
  • Buccal/Lingual Depression (Anterior Lobe): A Stafne bone cyst located in the anterior region of the mandible, adjacent to the buccal or lingual surface.
  • Inferior Border Depression (Posterior Lobe): A Stafne bone cyst located in the posterior region of the mandible near the inferior border.
  • Anterior Border Lingual Depression (RetroMolar Area): A Stafne bone cyst located in the retromolar region of the mandible near the anterior border lingual surface.

What are the Symptoms of Stafne Bone Cyst?

Stafne Bone Cyst typically presents with mild or no symptoms in the affected individual.

  • Asymptomatic
  • Swelling on the lower jaw
  • Occasionally noticed during routine dental X-rays
  • Painless bump in the mouth

What Causes Stafne Bone Cyst?

Stafne bone cysts are typically caused by a developmental anomaly where salivary gland tissue becomes entrapped in the jawbone during growth, leading to the formation of a cystic cavity.

  • Developmental anomaly
  • Salivary gland tissue displacement
  • Trauma or injury to the jaw
  • Genetic predisposition
