[Changes in the maxillary sinus wall after the Caldwell-Luc intervention. An experimental study]

Inferior nasoantral windows, with and without radical surgical removal of the maxillary sinus mucosa, were studied in ten New Zealand white rabbits. Surgical removal of the mucosa and the Caldwell-Luc operation were performed. After three months, the sinus cavity was smaller, the medial wall was retracted and the inner curtain was disturbed, and small antrostomies had closed.
