Treatment tactics the maxillary sinuses cysts of patients to whom dental implantation is planned

Abstract

Introduction: The modern strategy of the treatment of maxillary sinus cysts provides for the surgery in cases of clinically significant cysts, and in other cases – observation. When performing sinuslifting, cysts of the maxillary sinuses are a risk factor for complications. The objective of the study: to increase the effectiveness of treatment of patients with cysts of the maxillary sinus, who are scheduled for dental implantation. Material and Methods: The results of dental implantation in 124 patients with maxillary sinus cysts were studied in order to substantiate the feasibility of removing, before sinuslifting, not only cysts accompanied by complaints but also those located at a distance of 10 mm from the planned implantation site. Results: The frequency of Schneider membrane perforation during sinuslifting was observed in 12.1% of patients. Removing the cysts located within 10 mm from the dental implantation site before sinuslifting reduced the frequency of Schneider membrane perforations by 2.7 times and other complications by 3.7 times. Conclusion: When determining the treatment tactics for patients with maxillary sinus cysts to whom dental implantation is planned, the localization of the cyst in the sinus and its relationship between the ostiomeatal complex and the site of dental implantation should be taken into account. Removal of cysts of the maxillary sinus, located above the site of the planned dental implantation and within 10 mm from it, reduces the frequency of sinuslifting complications.
