Summary
Transnasal endoscopic surgery effectively treats juvenile nasopharyngeal angiofibroma (JNA), including cases with minimal intracranial extension. This minimally invasive approach shows promising results with low recurrence rates.
Area of Science:
- Otolaryngology
- Neurosurgery
- Endoscopic Surgery
Background:
- Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign tumor.
- Surgical management of JNA can be challenging due to its location and potential for recurrence.
- Transnasal endoscopic approaches offer a minimally invasive alternative for JNA resection.
Purpose of the Study:
- To evaluate the efficacy and surgical techniques of transnasal endoscopic procedures for treating JNA.
- To assess outcomes based on tumor staging, including intracranial extension.
Main Methods:
- Twenty-one patients with JNA underwent transnasal endoscopic surgery.
- Patients were staged according to intracranial extension (Group A: none, Group B: minimal).
- Surgical outcomes, including blood loss, residual tumor, and recurrence, were evaluated.
Main Results:
- Nineteen patients (Group A) had an average blood loss of 1000 ml with no residual or recurrent tumors.
- Two patients (Group B) with minimal intracranial extension had an average blood loss of 1500 ml.
- One patient in Group B had minimal residual tumor but no progression; the other had no recurrence.
Conclusions:
- Transnasal endoscopic surgery is a viable treatment for JNA confined to the nasal and nasopharyngeal cavities.
- This technique is also effective for JNA with sphenoid, ethmoid, and minimal intracranial invasions.
- The study supports the use of transnasal endoscopic techniques for a range of JNA presentations.
