Dental Implant in the Ethmoid Sinus

A 57-year-old woman presented with recurrent sinusitis of the left maxillary sinus. Computed tomography showed the presence of a foreign body in the left ethmoid sinus (Panel A). The patient had received an endosseous implant in the upper jaw 2 years earlier without complication. On transoral examination, the implant was unexpectedly absent; the mucosa covering the alveolar process was intact, and the remaining teeth were healthy. During endoscopic surgery, a dental implant in the ostiomeatal complex was visualized (Panel B; LW denotes lateral nasal wall, MT middle turbinate, and NS nasal septum) and extracted (Panel C; units of measurement are centimeters). The patient was discharged the day after surgery, with rapid relief of symptoms. Eight months later, she reported no residual symptoms; on nasal endoscopy, the maxillary sinusotomy was patent with normal mucosa. Displacement of dental implants into the sinus may be the result of improper positioning or the late consequence of periimplantitis and bone resorption

      I have been surfing online more than 3 hours today, yet I never found any interesting article like yours. It is pretty worth enough for me. In my view, if all webmasters and bloggers made good content as you did, the internet will be much more useful than ever before. edfaadkbfaee
