Case report: isolated lower lip lesion following cavernoma resection in prone position

Abstract Background Surgery in a prone position is necessary when access to posterior anatomical structures is needed. A procedure in this position is associated with complications such as injuries to the eyes, peripheral nerves, and pressure points and swelling of the tongue. We report a rare complication of isolated lower lip swelling following neck dissection in the prone position. Case presentation A 25-year-old male patient presented to the clinic with complaint of neck pain for the past 2 months. A cervical spine MRI was done which showed the presence of a cavernoma. C2 laminectomy was performed for resection of the tumor in prone position with the head fixed on a three-point Mayfield clamp. Postoperatively, isolated swelling of the lower lip was observed. The patient was managed conservatively. Conclusion Cervical spine surgeries done in prone positions carry an increased risk of postoperative vision loss and swellings including those of the oropharynx and in the periorbital region. Possible risk factors for such conditions include anemia, hypotension, long duration of surgery, and significant intraoperative hydration.
