Three-dimensional cranial expansion using distraction osteogenesis for oxycephaly.

Oxycephaly is associated with raised intracranial pressure as a result of the fusion of multiple cranial sutures. We have performed an effective and less invasive cranial expansion by means of three-dimensional cranial distraction for the treatment of oxycephaly with suspicion of increased intracranial pressure. We describe two oxycephaly cases and the surgical technique of three-dimensional cranial expansion using distraction osteogenesis.

Intramuscular benign lipoma of the temporalis muscle.

An intramuscular lipoma within the musculature of the head and neck is unusual. Most of them are infiltrating lipomas, and we know of no description of a well-circumscribed lipoma of the temporalis muscle. We present a 64-year-old woman who had a non-pulsatile, soft, mobile mass in the right temporal fossa. The lesion 11 x 8 x 3 cm in size was diagnosed using magnetic resonance imaging, it was resected, and she has recovered well with a good cosmetic result.

Staged cranial reconstruction after epidural abscess associated with dural substitute exposure.

UNLABELLED: Cadaveric dura mater was widely used for a long time but has recently been associated with the transmission of Creutzfelt-Jakob disease. Expanded polytetrafluoethylene sheet has been suggested as a suitable alternative in Japan. Recently epidural abscesses associated with exposure to Expanded polytetrafluoethylene have been on the increase in Japan. We experienced one case of staged cranial reconstruction for chronic ulcer of the head associated with MRSA epidural abscess. SURGICAL TECHNIQUE: the exposed expanded polytetrafluoethylene must be completely removed along with the skin. Reconstruction of dura mater should be made watertight with the application of autologous free fascia lata collected from the paralyzed thigh. Autologous free fascia lata is reconstructed with the rectus abdominis muscle so that there is no dead space remaining. Calvarial bone should be reconstructed in a separate operation as at a second stage.
