Migration of oral implants displaced in the maxillary sinus toward the sphenoid sinus is an extremely rare event. This case report is focused on the possibility of treating such a rare complication by means of endoscopic treatment through the nasal cavity.
A 45-year-old female patient received one oral implant for the substitution of the left first upper molar, but during the surgical procedure the implant was displaced in the maxillary sinus. Owing to a delay in treatment, a spontaneous migration of the implant in the sphenoid sinus occurred.
The implant was removed endoscopically through the nasal cavity: postoperative recovery was uneventful.
To the authors' knowledge, this case represents the first report concerning migration of an oral implant into the sphenoid sinus and demonstrates the reliability and safety of an endoscopically driven surgical removal of the foreign body, thus preventing potential complications with extremely low postoperative morbidity.
上颌窦内移位的口腔种植体向蝶窦迁移是一种极其罕见的情况。本病例报告聚焦于通过鼻腔进行内镜治疗来处理这种罕见并发症的可能性。
一名45岁女性患者接受了一枚用于替代左上第一磨牙的口腔种植体，但在手术过程中种植体移位至上颌窦。由于治疗延误，种植体自发迁移至蝶窦。
通过鼻腔内镜取出种植体：术后恢复顺利。
据作者所知，本病例是关于口腔种植体迁移至蝶窦的首例报告，证明了内镜驱动手术取出异物的可靠性和安全性，从而预防了潜在并发症，术后发病率极低。
