One-Stage Surgical Management of an Asymptomatic Maxillary Sinus Mucocele with Immediate Lateral Sinus Lift and Simultaneous Implant Placement: A Case Report

Year: 2025

Type: article

Abstract: Background: The relationship between dental implants and sinus mucoceles is an area of growing interest in oral and maxillofacial surgery, as therapeutic approaches for these conditions remain controversial. This case report presents a 48-year-old male with no significant medical history who sought dental care due to recurrent abscesses on the distal abutment of a five-unit maxillary bridge. Clinical and radiographic evaluations, including Cone-Beam Computed Tomography (CBCT), revealed a pathologic lesion associated with the second molar, insufficient alveolar bone height in the posterior maxilla, and a radiopaque mass on the sinus floor. Methods: A one-stage surgical approach was planned, involving the second molar extraction, the sinus cyst removal, sinus floor elevation, and simultaneous implant placement. The prosthetic restoration was completed six months postoperatively. Results: Over an 88-month follow-up period, no prosthetic complications were observed, and the patient reported high satisfaction with the restoration’s function and aesthetics. Conclusions: This case highlights a single-stage surgical strategy’s feasibility and long-term success in managing asymptomatic maxillary sinus mucoceles while optimizing implant placement and rehabilitation.
