Proptosis after hair pulling.

We describe proptosis due to a subperiosteal orbital hematoma that originated from a subgaleal bleed caused by hair pulling. A 13-year-old boy presented with a one-week history of progressive proptosis after his older sister pulled his hair during an argument. Computerized tomography showed a subgaleal hematoma and a right superior subperiosteal orbital hematoma. Progressive proptosis and compressive optic neuropathy developed, necessitating surgical evacuation with a favorable outcome.Hair pulling can result in a subgaleal bleed with extension to the orbital subperiosteal space. When managing patients with a subgaleal hematoma, this vision-threatening complication should be considered and treated accordingly.
