Torus Palatinus & Mandibularis

aka Palatal Torus · Mandibular Torus

Benign, non-neoplastic bony exostoses of the midline hard palate or lingual mandible; usually incidental but may interfere with denture construction.

§ overviewOverview

Localised bony overgrowth of the maxillary or mandibular alveolar cortical plate — a normal anatomical variant.

§ etiologyEtiology

  • 01Multifactorial: genetic (autosomal dominant with variable penetrance), functional (heavy occlusal forces, bruxism), environmental

§ epidemiologyEpidemiology

Torus palatinus: 20–35% adults, F > M. Torus mandibularis: 6–12%, often bilateral, lingual to premolars.

§ clinicalClinical Features

  • 01Slow-growing, painless, bony-hard midline palatal or bilateral lingual mandibular swellings
  • 02Thin overlying mucosa prone to trauma ulceration
  • 03May interfere with denture seating or speech

§ differentialDifferential Diagnosis

  • 01Osteoma (may be part of Gardner syndrome)
  • 02Ossifying fibroma
  • 03Peripheral exostosis

§ histopathHistopathology

  • 01Dense cortical or trabecular mature bone with minimal marrow

§ investigationsInvestigations

  • 01Clinical diagnosis; occlusal radiograph for extent if surgery planned

§ treatmentTreatment

  • 01No treatment required unless: interferes with prosthesis, causes speech problems, chronic mucosal trauma, or patient concern
  • 02Surgical removal: elevate mucoperiosteal flap, section with bur/osteotome, smooth with file, tension-free closure

§ complicationsComplications

  • 01Post-op haematoma, wound dehiscence, palatal fistula, sensory disturbance

§ prognosisPrognosis

Excellent; no recurrence after complete removal.

§ examKey Examination Points

  • 01Bilateral lingual mandibular = pathognomonic
  • 02Rule out Gardner syndrome if multiple osteomas

§ revisionQuick Revision Summary

  • 01Anatomical variant · surgery only if functional problem

§ vivaBDS Viva Questions

  • 01Gardner syndrome features?
  • 02Surgical approach to remove palatal torus?
  • 03Difference between torus and osteoma?
