従来法—Conventional cranioplasty

Conventional Cranioplasty for Craniosynostosis

Point

・頭蓋骨縫合早期癒合症における頭蓋拡大形成術式の1つに従来法がある．

・従来法は，骨延長法に比べ手術侵襲は大きくなるが，繊細な頭蓋形成が可能である．

・頭皮縫合の際にtensionがかかるため，頭蓋拡大距離に制限があり，術後に前進させた骨の後戻りが起こることがある．

　Conventional cranioplasty is a basic operative procedure for craniosynostosis. This procedure is more invasive, but can be completed in shorter treatment period than distraction osteogenesis. This surgery can allow delicate cranial reshaping, and is indicated in most age groups. The operative procedures may differ depending on the skull shape. During this procedure, complete brain release from the skull compression must be achieved. In most patients, bone flaps float from the dura mater after completion of craniotomy. The bone flap must be reshaped to the ideal form, and should be fixed with absorbable plates instead of titanium plates to avoid plate migration. To close the scalp, the galea should be sutured tight to avoid wound trouble. After the operation, patients should be followed up at an out-patient clinic; the skull and face shape should be checked by a neurosurgeon and plastic surgeon as the treated skull has risk of backslide, and development should be regularly checked by a pediatrician.
