Summary

Radical surgery offers high success rates for jugulotympanic paragangliomas (JTP) with low recurrence. Radiotherapy stabilizes tumors but carries risks, making surgery preferable when feasible for these vascular tumors.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Oncology

Background:

  • Jugulotympanic paragangliomas (JTP) are the most common middle ear and temporal bone tumors after acoustic neurinoma.
  • The optimal management strategy for these vascular tumors remains unclear.
  • This study reports institutional experience with JTP management.

Purpose of the Study:

  • To evaluate the effectiveness and outcomes of different therapeutic approaches for jugulotympanic paragangliomas.
  • To compare surgical, radiotherapeutic, and combined treatment modalities for JTP.
  • To inform clinical decision-making for JTP management.

Main Methods:

  • Retrospective analysis of 41 patients with JTP treated between 1973 and 1996.
  • Classification of tumors based on Fisch staging, with 49% exhibiting intracranial extension.

  • Patients were grouped by primary treatment: surgery, radiation therapy, or surgery followed by radiation therapy.

    • Main Results:

    • Surgical tumor removal achieved >95% success with no recurrence at 6-year follow-up, but significant morbidity (cranial nerve injury) was noted.
    • Radiotherapy in 75% of cases led to tumor stabilization (5-year follow-up) but posed a risk of radionecrosis.
    • One death occurred due to laryngospasm post-surgery.

    Conclusions:

    • Radical surgery is encouraged for JTP when feasible due to high success rates.
    • Radiotherapy is indicated for elderly patients, those at surgical risk, or with extensive tumors, aiming for stabilization.
    • Multidisciplinary management and genetic screening for familial cases are crucial for optimal JTP care.
