Craniotomy for posterior fossa and deep muscles incision and suture technique in suboccipital retrosigmoidal approach / 中华神经医学杂志

ABSTRACT

Objective To probe the technical processes of the suboccipital retrosigmoidal craniotomy with replacement of bone flap and deep muscles incision and suture and its clinical application. Methods The data of 40 patients undergoing suboccipital craniotomy to the cerehello-pontine angle lesions, deep muscles incision and suture in our hospital from May, 2003 to May, 2005 were analyzed retrospectively. Results All the procedures of craniotomy including removal of the bone flap, deep muscles incision and suture were accomplished safely with an average operation time of 40-60 min. Two patients appeared post-operative subcutaneous hydrops without CSF leakage and the majority can move their head freely sixth day after the operation. Conclusion Suboccipital retrosigmoidal craniotomy with replacement of bone flap, and deep muscles incision and suture, being a safe and feasible method, may decrease the happening of postoperative CSF leakage and encephalocele, and accelerate the recover of head movement.
