Analysis of patients' records and CBCT focused on patient\u2010related risk factors (sinus contours, thickness of membrane and lateral sinus wall, interfering septa, crossing vessels, former oroantral communication) and intervention\u2010related risk factors (surgical approach, sides, number of tooth units, and sites).

There were 19 cases of SMP (13.9%). Two significant factors were identified: maxillary sinus contours (<jats:italic>P<\/jats:italic>\u2009=\u2009.001) and thickness of the sinus membrane (<jats:italic>P<\/jats:italic>\u2009=\u2009.005).
