Signs, Symptoms, and Diagnosis of Cherubism - Appearance of people with cherubism caused by loss of bone in mandible replaced with excessive fibrous tissue - Cherubism causes premature loss of primary teeth and lack of eruption or displacement of permanent teeth - Condition usually fades as child grows, but in rare cases it continues to deform affected person's face - Cherubism affects the orbital area, creating an upturned eye appearance - Afflicted individuals may experience emotional trauma and interference with normal jaw motion and speech - Dental abnormalities, such as premature deciduous teeth and abnormal growth of permanent teeth, can indicate cherubism - X-ray and CT scans are used for initial study of the patient - Genetic testing, specifically sequence analysis of the SH3BP2 gene, is the definitive diagnosis tool - Cherubism may resemble neurofibromatosis, so proper diagnosis is important - Genetic counseling may be recommended to decrease occurrences of cherubism

Causes and Genetic Studies of Cherubism - Cherubism is autosomal dominantly linked - Males tend to express the disease more frequently than females - Mutation of the SH3BP2 gene is believed to be the cause of cherubism - Cherubism can also be combined with other genetic disorders - Mutations of the SH3BP2 gene are reported in 75% of cherubism cases - Several genetic studies have been conducted to better understand the underlying mechanisms of cherubism - Ongoing research aims to identify potential therapeutic targets for cherubism and develop more effective treatment strategies

Prevention of Cherubism - Genetic counseling may be the only way to decrease occurrences of cherubism - Lack of severe symptoms in parents may make it difficult to recognize the disorder - Testing for mutations prior to having children is optimal - Cherubism results from a genetic mutation, which can spontaneously occur - Prevention techniques may not be available

Treatment and Management of Cherubism - Treatment should be individually determined based on the progression of cherubism - Moderate cases may be watched until they subside or progress - Severe cases may require surgery to remove cysts and fibrous growths - Orthodontic treatment may be necessary to address dental problems - Patients with orbital issues may require ophthalmologic treatment - Regular dental and orthodontic care is essential to address dental abnormalities and malocclusion - Surgical interventions, such as debulking of the jaw swellings or orthognathic surgery, may be considered in severe cases or for cosmetic purposes - Long-term follow-up is necessary to monitor the progression of the disease and manage any complications that may arise

Prognosis and History of Cherubism - Cherubism does not have a poor prognosis in general - Condition does not progress beyond puberty - Jawbone lesions tend to resolve as the patient grows to adulthood - A progressively more normal jaw configuration is noted over time - Reliable statistics on prognosis are difficult to estimate due to the rarity of the condition - Cherubism was first documented and named in 1933 by Dr. W. A. Jones - Dr. Jones described a case of three siblings of the same family of Jewish Russian heritage - Facial deformity became obvious disfigurement by the time the children reached their late teens - The children underwent surgeries to reduce the swelling of their jaws - Four years following the surgeries, there was no reappearance of the swellings
