Transnasal needle biopsy provides a simple CT-guided approach for sampling posterior nasopharyngeal lesions. This minimally invasive technique shows promise for selected patient cases.

Area of Science:

  • Otorhinolaryngology
  • Neurosurgery
  • Radiology

Background:

  • Posterior nasopharyngeal lesions pose diagnostic challenges.
  • Minimally invasive biopsy techniques are crucial for accurate diagnosis.
  • Computed tomography (CT) guidance enhances procedural accuracy.

Observation:

  • Transnasal needle access was employed in two patients.
  • Lesions were located in the posterior nasopharynx.
  • The procedure was performed under CT guidance.

Findings:

  • A novel transnasal needle biopsy technique was successfully utilized.
  • The method proved simple and effective for the selected cases.
  • Detailed procedural steps for CT-guided sampling were documented.

Implications:

  • This technique offers a new, minimally invasive option for nasopharyngeal lesion biopsy.
  • CT guidance ensures precision and safety in transnasal sampling.
  • Further research may validate this approach for a broader patient population.
