Background: Decompressive craniectomy (DC) is performed to accommodate life-threatening brain swelling when medical treatment fails. This procedure carries the risk of developing traumatic subdural hygroma (TSH) that can adversely affect the neurological status of the patient. The treatment for persistence of TSH includes drainage and shunt placement or drainage and membranectomy. In this paper, we present treatment of two patients whose TSH was effectively treated with simple drainage and cranioplasty. Case Presentation: Patient 1: The patient is a 34-year-old female who had bilateral craniectomy for brain swelling. Four weeks later she became less interactive. CT scan showed bilateral subdural hygroma with 2 cm midline shift to the left. Her clinical status improved and CT scans showed resolution of the hygroma after simple evacuation of the hygroma and cranioplasty. Patient 2: The patient is a 57-year-old male who had post-traumatic acute subdural hematoma and brain swelling on the left side. The clot was evacuated and the bone flap was left out. After showing initial improvement, 10 weeks after the initial surgery the patient progressively worsened and became unresponsive. CT scans showed a large subdural hygroma on the right with midline shift to the left. Simple evacuation of the hygroma and cranioplasty was done. This resulted in radiological and clinical improvement of the patient. Conclusions: Both patients underwent simple drainage and cranioplasty, which resulted in clinical and radiological improvement. This finding suggests that other procedures such as membranectomy and shunting may not be necessary to treat TSH.
