Males exhibited larger sinus volumes, while dentition status showed no significant effect. Septa were present in approximately half the cases, most often in the middle region with predominant coronal orientation, and were linked to greater sinus volume. These findings highlight the value of individualized preoperative CBCT assessment for safe implant and sinus floor elevation planning and question the assumption that sinus pneumatization consistently follows tooth loss.
