Sclerosing osteomyelitis of Garré

Last revised by Joshua Yap on 27 Dec 2022

Sclerosing osteomyelitis of Garré is a specific type of chronic osteomyelitis. It mainly affects children and young adults. It typically affects the mandible and is commonly associated with an odontogenic infection resulting from dental caries.

It often presents as a localized overgrowth of bone on the outer surface of the cortex. This mass of bone, which is supracortical but subperiosteal, is smooth, fairly calcified, and is often described as a duplication of the cortical layer of the mandible.

The redundant cortical layering of the bone (onion skinning) is often considered a pathognomonic feature 8.

It was first described by Carl Garré in 1893 6.
