Glomus tumors: symptom variations and magnetic resonance imaging for diagnosis.

Background: The typical clinical symptoms of glomus tumors are pain, tenderness, and sensitivity to temperature change, and the presence of these clinical findings is helpful in diagnosis. However, the tumors often pose diagnostic difficulty because of variations in presentation and the nonspecific symptoms of glomus tumors. To the best of our knowledge, few studies have reported on the usefulness of magnetic resonance imaging (MRI) in diagnosing glomus tumors in patients with unspecific symptoms.

Dual midfacial distraction osteogenesis for Crouzon syndrome: long-term follow-up study for relapse and growth.

Purpose: Rigid external distraction osteogenesis is regarded as a standard treatment for congenital midfacial hypoplasia. However, external distraction for the upper portion of the midface is not as effective and tends to rotate the midfacial segment in a counterclockwise direction. Moreover, patients poorly tolerate it because of the device's bulkiness.
