    Caldwell-Luc (Radical Antrostomy), Inferior Meatal Antrostomy & Canine Fossa and Inferior Meatus Punctures
    (2025-03-03) Fagan, Johan
    The Caldwell-Luc operation involves creating an opening into the maxillary antrum through the canine fossa via a sublabial approach. Canine fossa (CFP) & inferior meatal puncture are used to obtain samples of pus from the antrum, to irrigate the antrum (“antral washout”), or as an adjunct to endoscopic ethmoidectomy. The Caldwell-Luc operation involves enteringthe maxillary sinus via an opening in the thin bone of the canine fossa (Figures 1-3). A series of eminences overlie the roots of the teeth on the inferior part of the face of the maxilla (Figures 2, 3). Just above the eminences of the incisor teeth is a depression called the incisive fossa; it gives origin to the depressor alae nasi. The nasalis muscle arises just lateral to it (Figure 2).
