Caldwell-Luc procedure
Pronunciation: KALD-wel LOOK
Surgical approach to the maxillary sinus through the canine fossa, creating a large antrostomy for drainage and access.
Full Definition
The Caldwell-Luc procedure is a surgical technique that provides wide access to the maxillary sinus by creating an opening through the anterior wall of the maxilla in the canine fossa region. Originally described for treating chronic sinusitis, it involves removing the anterior bony wall of the sinus and creating a large communication with the nasal cavity through the inferior meatus. In oral and maxillofacial surgery, this approach may be used for removing large cysts, foreign bodies, or tumors from the maxillary sinus, or for reducing maxillary fractures. The procedure requires careful attention to avoid injury to dental roots and may result in some numbness of the upper teeth and lip.
Usage
Usage note: Named after the surgeons who described the technique; capitalize both names.
