Conditions

Cleft Palate

Brief summary

The purpose of this study is to evaluate the change of the optic nerve sheath diameter according to the change of the neck position in pediatric patients undergoing palatoplasty.

Detailed description

Palatoplaty is performed under neck extension in patients with cleft palate. The purpose of this study is to evaluate the effect of neck extension on the ultrasonographic optic nerve sheath diameter during palatoplasty.

Interventions

PROCEDURENeck extension

The neck extension is routine posture during palatoplasty. We will evaluate the change in optic nerve sheath diameters before and after neck extension.
