A radical maxillary sinusotomy, also known as an antrostomy, is a surgical procedure that involves creating an opening into the maxillary sinus to facilitate access for treatment. This specific procedure, referred to as the Caldwell-Luc operation, is performed to remove antrochoanal polyps, which are abnormal growths that originate in the maxillary sinus. The procedure begins with an incision made in the oral cavity, specifically over the canine tooth, extending towards the first premolar. This approach allows the surgeon to access the maxillary sinus effectively while minimizing external incisions. The use of electrocautery aids in the dissection through the soft tissue and periosteum, ensuring that the surrounding structures, such as the infraorbital nerve, are preserved. Once the maxillary sinus is accessed through the canine fossa, the opening is enlarged to allow for adequate drainage and removal of any pathological tissue. The procedure is comprehensive, as it not only addresses the polyps but also involves obtaining specimens for culture and sensitivity testing, which is crucial for diagnosing any underlying infections. The irrigation of the maxillary sinus is performed to clear any debris and ensure a clean surgical field. This procedure is particularly indicated for patients experiencing nasal obstruction and related complications due to the presence of antrochoanal polyps, which can lead to further issues such as serous otitis media if left untreated.
