The maxillary sinus roof serves as a reliable landmark for safe endoscopic skull base surgery when traditional structures are compromised. This anatomical reference ensures secure entry into the sphenoid sinus for tumor debulking.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Endoscopic Sinus Surgery

Background:

  • Anatomic landmark identification is challenging in endoscopic skull base and revision sinus surgery due to altered anatomy from tumors.
  • Traditional landmarks like the superior turbinate may be compromised or removed in pathological conditions.
  • Existing surgical rules, such as staying below the orbital floor to enter the sphenoid, require anatomical validation.

Purpose of the Study:

  • To evaluate the maxillary sinus roof as a reliable intraoperative landmark for endoscopic skull base surgery.
  • To assess the safety and efficacy of using the maxillary sinus roof to guide surgical dissection towards the sphenoid sinus.

Main Methods:

  • Computed tomography (CT) scans of 300 paranasal sinus systems were analyzed.

  • Measurements of maxillary sinus roof height relative to the nasal floor were taken.
  • Proportions and relative heights of the maxillary sinus, ethmoid roof, cribriform fossa, and sphenoid planum were assessed.

    • Main Results:

    • The maxillary sinus roof was consistently below the skull base level in 100% of cases relative to the cribriform and sphenoid planum.
    • The mean distance of the maxillary roof below the skull base was 10.1 mm (cribriform) and 11.0 mm (sphenoid).

    Conclusions:

    • The maxillary sinus roof is a robust anatomical landmark for safe dissection in endoscopic skull base surgery.
    • It facilitates safe entry into the sphenoid sinus for pathology removal when conventional landmarks are unavailable.
    • This landmark aids in safe posterior dissection and debulking of tumors in complex sinus surgeries.
