• Title : Anatomical consideration for the lateral approach to the maxillary sinus lifts

• Abstract : The lateral approach to maxillary sinus lift surgery requires careful anatomical consideration to ensure safety and predictability. The primary goal is to achieve sufficient vertical bone height in the posterior maxilla for implant placement. Key factors influencing the procedure include vascularization, mucosal thickness, oro-antral communication, and antral septa. The vascular network of the antero-lateral sinus wall involves both extraosseous and intraosseous anastomoses, most notably between the posterior superior alveolar artery and the infraorbital artery. Although vessel transection rarely causes severe hemorrhage, preoperative CBCT evaluation helps minimize risks. Window preparation is safer when performed mesially. Mucosal thickness, often affected by sinus pathology or retention cysts, must be evaluated preoperatively. Aspiration or removal of lesions can maintain osteomeatal patency and avoid postoperative complications. Oro-antral communication, if present, should be securely occluded with a membrane to prevent infection and promote bone regeneration within the sinus cavity. Antral septa are relatively common, with higher prevalence in edentulous maxillae. Their presence requires modification of the surgical approach, such as preparing multiple windows to avoid membrane perforation. Overall, success in lateral sinus lift procedures depends on comprehensive patient history, thorough CBCT analysis, and customized surgical planning. By addressing vascular variations, mucosal pathology, oro-antral defects, and sinus septa, clinicians can reduce complications and enhance treatment outcomes.
