Although the entity is widely reported, the literature mostly consists of case reports. “Sinking skin flap syndrome” (SSFS) is defined as a secondary neurological deterioration in the presence of a sinking skin flap in patients with large craniectomies. Urgent head CT scan was performed which, however, did not reveal new pathology, but only demonstrated findings of early stage sinking skin flap syndrome (Fig. Besides, the traditional managements reducing the intracranial pressure for herniation may exacerbate paradoxical herniation, therefore, timely diagnosis and correct treatments are significantly important. It was first described by Grant and Norcross in 1939 as a constellation of symptoms including dizziness, undue fatigability, discomfort at the defect. The problem was considered to have been asymptomatic sinking skin flap syndrome (SSFS). The sinking skin syndrome (SSS) or syndrome of the trephined, as first described by Grant and Norcross,[] is a very particular complication after a decompressive craniectomy (DC). Infrequently, neurologic deteriorations accompanied by sunken scalp may occur after DC. This phenomenon may result from CSF hypovolemia, atmospheric pressure gradient that may be aggravated by CSF diversion, dehydration, and position change1,4. The shrinkage and displacement of the brain structure is caused by the differences in intracranial pressure and exter- nal atmospheric pressure. It still remains a poorly understood and underestimated entity. The sinking skin flap syndrome is a complication of decompressive craniectomies.
