Modified Dandy Stair-Step Incision for Retrosigmoid Craniotomies to Reduce Postoperative Complications in Skull Base Surgery.

Among 73 patients, 29 (39.7%) underwent the modified Dandy technique.

Baseline characteristics were similar between the two groups, with 41 of them being female (56.2%), the median age being 59 (interquartile range [IQR]: 50-67), and 44 having never smoked (60.3%).

The most common indications for surgery were vestibular schwannomas (53.4%), meningiomas (24.7%), and metastatic lesions (15.1%), while the rest were other lesions (6.8%).

Three patients in the control group (6.8%) had multiple complications, one of whom required multiple reoperations for persistent pseudo-meningocele.
