Sinking of bone flap-looking beyond cosmesis and costs

Dear Editor, Decompressive craniectomy is a common procedure performed for raised intracranial hypertension with obligatory subsequent bone flap replacement or cranioplasty at varying intervals, for various side effects of the lack of bone flap, well described in the literature. However, the complications during and following the replacement of bone flap did not strike the limelight, which may require another surgical intervention.[1‐3] Sinking of entire bone flap following the cranioplasty procedure is much more than cosmesis for the antecedent neurological deficits it produces; hence righteously qualifies to be termed as “sunken bone flap syndrome”.
