Summary

Endoscopic transnasal sphenoidotomy (ETNS) is effective for inflammatory sphenoid sinus disease (ISSD). ETNS without ethmoidectomy suits isolated ISSD, while ETNS with ethmoidectomy is needed for concurrent paranasal sinus issues.

Area of Science:

  • Otolaryngology
  • Endoscopic Sinus Surgery
  • Rhinology

Background:

  • Inflammatory sphenoid sinus disease (ISSD) presents diagnostic and therapeutic challenges.
  • Computed tomography (CT) staging is crucial for ISSD management.
  • Endoscopic transnasal sphenoidotomy (ETNS) is a minimally invasive surgical approach.

Purpose of the Study:

  • To evaluate the efficacy of ETNS, with or without ethmoidectomy, for ISSD.
  • To determine the optimal surgical approach based on disease extent and staging.
  • To analyze surgical outcomes and complications associated with ETNS.

Main Methods:

  • Retrospective review of 42 patients with ISSD undergoing ETNS.
  • ETNS performed with (n=37) or without (n=5) ethmoidectomy.

  • Disease staging based on CT findings using a standardized system.

    • Main Results:

    • Postnasal drainage was the most frequent symptom (88.1%).
    • Complications occurred in 19% of patients, including hemorrhage and injury to the lamina papyracea.
    • Isolated sphenoid disease (11.9%) and unilateral disease (38.1%) were noted, with disease stages ranging from 1 to 3.

    Conclusions:

    • ETNS without ethmoidectomy is favorable for isolated ISSD.
    • ETNS with ethmoidectomy is necessary for concurrent disease in other paranasal sinuses.
    • Surgical technique selection should be guided by ISSD extent and CT staging.
