Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Skull Base Surgery

Background:

  • The Draf 3 frontal sinusotomy (modified Lothrop procedure) is utilized for challenging rhinosinusitis and other frontal sinus conditions.
  • Indications include frontal sinus mucoceles, cerebrospinal fluid leaks, and tumors requiring surgical access.

Purpose of the Study:

  • To present the "Outside-In" frontal drill-out surgical approach.
  • To detail a novel technique for frontal sinus access and management.

Main Methods:

  • Descriptive case series outlining the "Outside-In" frontal drill-out technique.
  • Emphasis on early olfactory neuron identification and maximal bone removal.

Main Results:

  • The "Outside-In" approach prioritizes early identification of the first olfactory neuron.
  • Maximal bone removal is achieved while preserving the posterior table mucosa.
  • The technique allows for early identification of anatomical boundaries.

Conclusions:

  • The "Outside-In" frontal drill-out provides an unobstructed surgical view.
  • Bone removal is rapid and efficient, ensuring safety.
  • This robust technique relies on established anatomical landmarks for predictable outcomes.
