I compiled and analyzed 112 patients in whom 182 sides of diffuse chronic sinusitis were subjected to endoscopic endonasal ethmoidectomy with the creation of a large communication between the maxillary sinus and frontal sinus. These initial sinus surgical cases have been followed up postoperatively for periods ranging from 1 year to 5 years and 9 months. The age range was from 15 to 70 years, with a mean of 35.8 years.
The improvement rate of clinical symptoms by questionnaire, the improvement rate and the postoperative period required for cure of maxillary sinus lesion, and also the postoperative conditions of the ethmoid sinus, nasofrontal duct, fontanelle and maxillary sinus are analyzed.
The subjective nasal symptoms improved in more than 99% of the patients. However, nasal discharge and postnasal discharge persisted in a few cases.
The overall improvement rate in the objective endoscopic findings after surgery was 90-95%. Complete cure was not able to be obtained in 5-10% of the cases. They apparently require another treatment or surgical procedure.
Endoscopic endonasal sinus surgery enables a precise technique and facilitates the prevention of serious surgical complications, thereby improving the final results.
