The sinus augmentation procedure of the jaw sinus (SAP) is a surgical technique which permits the prosthetic rehabilitation of the edentulous saddles by the insertion of dental implants where unfavourable conditions exist for their application. Nevertheless, apart from malignant tumors, benign pathologies exist, such as mucocele or radicular cysts, which can complicate the SAP, causing sinusal disturbances. In this study we describe our experience of SAP in patients with mucocele of the jaw sinus, and describe our surgical technique without the preventive emptying of the mucocele. Based on our experience, the SAP operation can be carried out without complications if the distance between the top of the mucocele with SAP and the osteomeatal complex (OMC) is 22 mm, or for mucocele no larger than 18 mm. In fact, these parameters guarantee that, because of the lifting of the sinusal membrane, the antral drainage (AD) duct does not alter or become obstructed.
