Summary
Jacob's disease, a rare condition causing limited mouth opening, involves a new joint forming between the coronoid process and malar bone. This case highlights diagnosis and surgical treatment for this uncommon condition.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthopedic Surgery
- Pathology
Background:
- Jacob's disease is an uncommon condition characterized by the formation of a new joint between an elongated coronoid process and the malar bone.
- First described in 1853 and named in 1899, it typically presents with progressive limitation of mouth opening and facial asymmetry, primarily affecting young patients.
Observation:
- A 52-year-old female patient presented with a 2-year history of progressive mouth opening limitation.
- She had a history of childhood trauma to the right preauricular region.
- Computed tomography (CT) revealed elongation of the right coronoid process impinging on the ipsilateral malar bone, causing deformity.
Findings:
- Histopathology confirmed bone hyperplasia, cartilage, and a synovial capsule, establishing the new joint characteristic of Jacob's disease.
- The surgical intervention, performed via an intraoral vestibular approach, successfully addressed the condition.
Implications:
- This case underscores the importance of considering Jacob's disease in patients with progressive mouth opening limitation, especially with a history of trauma.
- Accurate diagnosis through imaging and histopathology is crucial for effective management.
- Surgical intervention can provide a successful treatment outcome for this rare condition.

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:12General Case of Eccentric Axial Loading
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical bending,...

01:26Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:30Coronary Artery Disease III: Clinical Manifestations
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
