Caldwell-Luc Antrostomy
Caldwell-Luc antrostomy is a traditional open surgical procedure used to treat chronic maxillary sinus disease that does not respond to medical therapy or less invasive endoscopic sinus surgery. It involves creating an opening in the maxillary sinus through the upper gum (canine fossa) to directly remove diseased tissue, cysts, polyps, or foreign bodies. Although modern endoscopic sinus surgery has largely replaced it, Caldwell-Luc remains an important option in complex or recurrent cases. The procedure aims to restore proper sinus drainage, relieve chronic facial pain, and eliminate persistent infection.
About Procedure
The maxillary sinuses are air-filled cavities located in the cheekbones that help humidify inhaled air and lighten skull weight. When these sinuses become chronically infected or obstructed, patients may develop persistent facial pain, nasal blockage, foul-smelling discharge, headache, and recurrent sinus infections. Caldwell-Luc antrostomy is performed under general anesthesia by making an incision in the upper gum above the canine teeth, allowing direct access to the maxillary sinus. The surgeon removes infected mucosa, polyps, or debris and creates a drainage pathway into the nasal cavity. While functional endoscopic sinus surgery (FESS) is now the preferred approach, Caldwell-Luc is still used when endoscopic access is limited or when extensive disease is present. Recovery involves gradual healing of the incision and improvement of sinus ventilation over several weeks.
When to Consider
Caldwell-Luc antrostomy is considered in patients with chronic maxillary sinusitis that does not improve with medications or endoscopic surgery, recurrent sinus infections, maxillary sinus cysts, foreign bodies in the sinus, or fungal sinus disease. It may also be recommended when anatomical obstruction prevents effective endoscopic access. Persistent facial pain, nasal blockage, and repeated antibiotic use despite treatment are key indicators for evaluation.
