Unexpected Nasal Cavity Entry of a Maxillary Sinus Implant During Intraoperative Removal

Year 2025, Volume: 4 Issue: 4, 108 - 112, 22.12.2025

Abstract

Dental implant displacement into the maxillary sinus is a well-documented complication in implantology. This case report presents a rare intraoperative event where a dental implant, initially displaced into the maxillary sinus due to insufficient bone support, migrated into the nasal cavity during surgical retrieval. A 45-year-old female patient with chronic maxillary sinusitis and an existing oroantral fistula underwent surgical treatment using the Caldwell-Luc approach. Despite thorough sinus debridement, the implant could not be located intraoperatively, and a cone-beam computed tomography (CBCT) scan revealed its unexpected presence in the nasal cavity, near the ostium. The implant was successfully retrieved through the sinus window, and the fistula was closed using a buccal fat pad. This case highlights the need for meticulous intraoperative assessment and readiness for atypical complications such as nasal migration of implants, particularly in patients with prolonged sinus pathology.

Maksiller Sinüse Yerdeğiştiren İmplantın Çıkarılamsı Sırasında Beklenmedik Şekilde Nazal Kaviteye Yer Değiştirmesi

Abstract

Dental implantın maksiller sinüse yer değiştirmesi, implantolojide iyi belgelenmiş bir komplikasyondur. Bu olgu sunumu, nadir görülen intraoperatif bir durumu aktarmaktadır: Başlangıçta yetersiz kemik desteği nedeniyle maksiller sinüse yer değiştiren bir dental implantın cerrahisi sırasında nazal kaviteye yerdeğiştirmiştir. Kronik maksiller sinüzit ve mevcut oroantral fistülü olan 45 yaşındaki kadın hastanın, Caldwell-Luc yaklaşımı ile cerrahisine karar verilmiştir. Sinüsün kapsamlı debridmanına rağmen implant intraoperatif olarak bulunamamış, intraoperatif olarak alınan konik ışınlı bilgisayarlı tomografi (CBCT) taraması implantın beklenmedik şekilde nazal kavitede olduğunu göstermiştir. İmplant sinüs penceresi yoluyla başarılı bir şekilde çıkarılmış ve fistül bukkal yağ dokusu kullanılarak kapatılmıştır. Bu olgu, özellikle uzun süreli sinüs patolojisi bulunan hastalarda, implantların nazal kaviteye yerdeğiştirmesi gibi atipik komplikasyonlara karşı dikkatli intraoperatif değerlendirme ve hazırlıklı olmanın önemini vurgulamaktadır.
