Summary
Jacob's disease, a rare condition causing joint formation between the mandibular coronoid process and zygomatic body, can lead to mouth opening limitations. Surgical intervention and histopathology confirmed cartilage-capped exostoses as the cause.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Pathology
Background:
- Jacob's disease is a rare condition characterized by an anomalous joint between the mandibular coronoid process and the zygomatic body.
- Chronic temporomandibular joint (TMJ) disk displacement is a potential etiological factor for coronoid process enlargement.
Observation:
- A 23-year-old woman presented with long-standing TMJ dysfunction, restricted interincisal opening, and progressive zygomatic asymmetry.
- The patient underwent simultaneous intraoral coronoidectomy and TMJ arthroscopy.
Findings:
- Histopathological examination of the coronoid sample revealed cartilage-capped exostoses with articular fibrous cartilage.
- The surgical and diagnostic findings confirmed Jacob's disease in the patient.
Implications:
- Jacob's disease, though rare, should be considered in the differential diagnosis of patients with progressive mouth opening limitation.
- TMJ dysfunction may be an underlying cause or concurrent condition associated with Jacob's disease.
- This case highlights the importance of thorough evaluation for rare conditions presenting with TMJ symptoms and facial asymmetry.
