II. Pathophysiology
- Potential space between skull periosteum to scalp galea
- Extends posteriorly from orbital ridges to occiput
- Extends laterally to ears
- Blood accumulates in this potential space
III. Risk factors
- Repeated use of vacuum extractor
- Coagulopathy
IV. Symptoms
- Insidious Hematoma growth
- May extend to involve entire calvarium
- Develops over hours to days
V. Signs
- Scalp pits as if edematous
- Periorbital or auricular Ecchymosis
- Hematoma crosses Suture lines
VI. Management
- Vigilant observation
- Scalp pressure dressing
- Transfusion
- Phototherapy
VII. Complications
- Hemorrhagic Shock
- Infection
