Abstract：Objective To explore the clinical manifestations, the surgical techniques of pontile cavernous malformations (PCMs) and curative effects of surgery on them. Methods The clinical data of 9 patients with PCMs, who underwent microsurgical resection from January, 2009 to January, 2016, were analyzed retrospectively. Of 9 patients with PCMs aged from 26 to 71 years, 3 were male and 6 female. The surgical approaches included suboccipital, retrosigmoid, subtemporal-transtentorial and far lateral approaches. Results Of 9 patients with PCMs, 8 received total resection of PCMs and 1 subtotal. Neurological functions were improved in 7 patients and unchanged in 1, and the symptoms of prosopoplegia and abducens paralysis became worse in 1 after the surgery. No patients died from the surgery. All the patients were followed up from 5.5 to 72 months (mean, 26.3 month). There was cerebral hemorrhage again in 1 patient 5 years after the surgery. Conclusions The symptoms of prosopoplegia and abducens paralysis are hard recovered, and the ataxia, facial sensory disturbances and hemi-sensory disturbances may be recovered well in the patients with PCMs after the surgery. The therapeutic effect of microsurgery through suboccipital retrosigmoid transtrigeminal root approach on PCMs located in the pons arms and closed to the fourth ventricles are better than those of microsurgery through sub-occipital midline approach.
