Endoscopic Frontal Sinus Drill-out (Modified Lothrop)
Indications:
- Symptomatic chronic frontal sinusitis
- Frontal stenosis despite prior more limited attempts at opening of frontal recess
Highlights:
- Anterior-posterior opening from olfactory cleft (posteriorly) to bone just below nasal skin (anteriorly)
- Side-to-side opening from lamina papyracea to lamina papyracea including removal of both middle turbinates and superior septum
Keep in Mind/Things to Remember:
- Superior septectomy improves access for drilling
- Diameter will often shrink postoperatively due to scar contraction
