To analyze the outcomes of microsurgically treated jugular paragangliomas with control of bleeding from the inferior petrous sinus.Study Design:
Retrospective patient review.Setting:
A single university hospital.Patients:
Forty-three patients with jugular paragangliomas were diagnosed in the past 7 years in our clinic.Main Outcome Measures:
Surgical tumor control, intraoperative blood loss, intraoperative management of the facial nerve, and the preoperative and postoperative function of the lower central nerves.Results:
Twenty-six patients underwent microsurgical treatment. Eighteen tumors were class C2 (69.2%), six were class C3 (23.1%), and two were class CDe1 (7.7%). Gross total tumor resection was achieved in 92.3% of the patients. The mean blood loss during surgery was 438.5 ml. The recurrence rate was 3.8% over a mean follow-up of 29.2 months. New facial palsy and lower cranial nerve deficit occurred in 42.3 and 11.5% of the patients, respectively.Conclusion:
The infratemporal fossa approach type A with sigmoid sinus tunnel-packing or push-packing technique facilitated the control of bleeding from the inferior petrous sinus and improved the outcomes of microsurgical treatment for jugular paragangliomas.
