Postoperative pain following excision of acoustic neuroma by the suboccipital approach: observations on possible cause and potential amelioration.
Incisional pain and headache have been reported following cerebellopontine angle surgery via the suboccipital approach. The high incidence and severity of pain determined in a retrospective study of acoustic tumor patients prompted the present prospective study. Various modifications of the suboccipital approach have been employed in an attempt to isolate a possible cause and potential method of minimizing this problem. The results of this study suggest that pain may be caused, in part, by adherence of healing nuchal soft tissue to underlying dura following suboccipital craniectomy. The substitution of a craniotomy with bone flap replacement, which prevents such adhesion, appears to have significantly reduced the postoperative pain associated with the suboccipital approach.
