Exploration of technique for preservation of external-middle ear structure in surgery of jugular foramen paraganglioma(appended 2 case reports)
Objective:To investigate the feasibility and effect of the modified surgery of the classic infratempo-ral fossa type A approach for the surgical treatment of jugular foramen paraganglioma with preservation of the ex-ternal and middle ear structures.Methods:The medical data of 2 patients with jugular foraminal paraganglioma treated by sublabyrinthic-transmastoid approach were retrospectively analyzed.The clinical feature,degree of tumor resection,postoperative facial nerve function and hearing retention,and the incidence of postoperative com-plications were evaluated.Results:Two patients were both female,and were pathologically confirmed as paragan-glioma.The tumor of case 1 was staged as C2De1,and case 2 as C1De1.Tumors were completely resected in both patients.Case 1 suffered infection after surgery,with residual tympanic membrane perforation and mixed deaf-ness.Case 2 developed mild facial paralysis(grade Ⅱ)after surgery,and recovered after symptomatic treatment.There was no tumor residue or recurrence during half a year of follow-up.Conclusion:Surgical treatment of cer-tain paragangliomas in the jugular foramen with a combined sublabyrinthic-transmastoid and upper neck approach might achieve both complete resection of the tumor and preserving the structure and function of the outer-middle ear.This procedure is suitable for paragangliomas restricted in the jugular foramen area,with no or limited in-volvement of the internal carotid artery(C1 or C2),and with no or mild hearing loss.
