Mean age was 65.96 years ± 14.23. Twelve patients had more than one implant penetrating the maxillary sinus, and seven of them had bilateral sinus perforation. Estimated implant penetration was ≤3 mm in all cases. The average clinical and radiological follow‐up was 9.98 years ± 3.74 (range 60–243 months). At the follow‐up appointments, there were no clinical or radiological signs of sinusitis in any patient.</p> </sec> <sec id="lary24189-sec-0005" sec-type="section"> <title>Conclusion</title> <p>This long‐term study, spreading over a period of up to 20 years, indicates that no sinus complication was observed following implant penetration into the maxillary sinus. Furthermore, absence of occurrence of such complications is related to the maintenance of successful osseointegration. A contrario, and in the presence of an acute or chronic maxillary sinusitis, the differential diagnosis must always consider other potential odontogenic and nonodontogenic etiologies.</p> </sec> <sec id="lary24189-sec-0006" sec-type="section"> <title>Level of Evidence</title> <p>2b. <italic>Laryngoscope</italic>, 123:2958–2961, 2013</p> </sec> </abstract>
