Iceberg lesion-A rare case of chronic osteomyelitis of the jaw with underlying radicular cyst: A case report.

Osteomyelitis is an inflammatory condition of the bones that often starts with an infection of the medullary cavity and swiftly extends to the haversian system and periosteum. If drainage and antimicrobials are ineffective, acute osteomyelitis may progress to chronic osteomyelitis. Here, we offer a unique case that analyzes the radiographic and clinical characteristics of osteomyelitis with underlying disease. Cysts and cyst-like lesions of the jaws must be diagnosed and evaluated using radiographic findings in conjunction with clinical complaints. This case study examines the circumstances that led to the diagnosis of osteomyelitis and demonstrates several noteworthy lessons. As decortication is less invasive and more effective at treating primary chronic osteomyelitis than peripheral or segmental excision of the jaw, and the use of vancomycin as local hard and soft tissue dressing over the surgical site, we emphasize its significance.
