Purpose: To present a case series treated by inferior meatal antrostomy as a prophylactic maneuver after the placement of zygomatic implants to decrease the risk of sinusitis.
Materials and Methods: All patients undergoing zygomatic implant placement using the lower meatal antrostomy protocol between June 2011 and March 2019 at the Department of Oral and Maxillofacial Surgery, Universidad El Bosque, were included. Patients were evaluated after 12 months of the procedure using clinical and radiologic criteria described by Kuriyama and Reiskin.
Results: Forty-eight patients were included, in whom 184 implants were placed. Complications were as follows: paresthesia (6.2%), orosinusal fistula (4.1%), skin infection (2.1%), and loss of the implant (1.6%). There were no cases of sinusitis.
Conclusion: This study provides evidence that the technique is effective and should be considered because of its simplicity. The inferior meatal antrostomy has been proven to be a simple, effective, and reliable technique to decrease the risk of sinusitis associated with the placement of zygomatic implants.
