Aside from endodontic causes, we frequently encounter problems caused by implant placement and bone augmentation techniques, which present a distinct pathophysiological profile compared to classic ODS. This study analyzed the clinical features of pre-implant (Group I) and implant-related ODS (Group II) to establish surgical management strategies according to the Felisati classification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective single-center study analyzed 45 patients treated between December 2020 and December 2025. Patients were classified according to the Felisati classification into Group I (preimplantological treatment complications) and Group II (implantological treatment complications). We evaluated clinical variables -etiology, osteomeatal complex (OMC) obstruction, foreign body presence, and oroantral communications (OAC)\u2014and surgical strategies adopted: Endoscopic Sinus Surgery (FESS), exclusive oral approach, or a combined simultaneous technique.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Implant-related cases (Group II;\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200937) dominated the cohort (82.2%), with 8 preimplantological complications (Group I). Females accounted for 66.7%. In Group II, chronic sinusitis affected 70.3% of patients, with high incidence of foreign bodies and OACs (64.9% each). To manage this complex scenario, we favored a combined simultaneous approach in the majority of Group II cases (59.5%); we reserved the exclusive oral approach for 27.0% of patients and limited exclusive FESS to 13.5%, primarily for implant preservation. Similarly, in Group I, where chronic sinusitis affected 75% of patients, the combined approach was performed in half the cases, while FESS alone was utilized in 37.5% to retrieve dispersed graft material. At the 3-month follow-up, primary complete resolution was observed in 44\/45 patients (97.8%). Only one patient (Group II) experienced a recurrence of the oro-antral communication, which was successfully closed after a secondary surgical intervention, ultimately leading to a 100% final success rate.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Implant-related and pre-implant ODS are distinct clinical entities often complicated by OMC obstruction and foreign body reactions. Although surgical planning requires case-by-case customization, in our experience, the combined simultaneous approach represented an effective primary strategy for complex cases, while exclusive approaches were reserved for selected patients. Complete short-term clinical and endoscopic resolution was observed in the cohort at the 3-month follow-up.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fsurg.2026.1862910","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T05:45:03Z","timestamp":1782452703000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Management of odontogenic sinusitis related to dental implants and maxillary sinus grafting: a retrospective single-center study"],"prefix":"10.3389","volume":"13","author":[{"given":"Lorenzo","family":"Sabatino","sequence":"first","affiliation":[{"name":"Unit of Otolaryngology, Fondazione Policlinico Universitario Campus Bio-Medico","place":["Rome, Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michele Antonio","family":"Lopez","sequence":"additional","affiliation":[{"name":"Unit of Otolaryngology, Fondazione Policlinico Universitario Campus Bio-Medico","place":["Rome, Italy"]},{"name":"Specialised Odontostomatology Department of Head and Neck and Sensory Organs, Division of Oral Surgery and Implantology, Fondazione Policlinico Universitario A.
