     Recently, dental implant therapy has been routinely undertaken at many dental hospitals and institutions. Consequently, complications associated with dental implant treatment have also increased.

     We report on patients with a foreign body (dental implants) in the maxillary sinus detected following dental implant placement and maxillary sinus augmentation surgery.

     Endoscopic sinus surgery is indicated and is the procedure of first choice for the extraction of a dental implant occurring as a foreign body in the maxillary sinus. A window is made in the lateral wall of the inferior meatus (medial wall of the maxillary sinus) and the foreign body is extracted using a straight rigid endoscope. This surgical procedure was minimally invasive and can be performed as a short stay surgery.

     It is said that the stapes gusher results in severe sensorineural hearing loss in most cases. Herein, we report a case of stapes gusher in whom the hearing ability was preserved. The patient was an 18-year-old man with a history of bilateral hearing loss from a young age, who visited our hospital for investigation of the cause of his mixed hearing loss. A temporal-bone CT revealed a low-density area around the cochlea. We diagnosed the patient as having otosclerosis, and performed stapes surgery. During the operation, when we fenestrated the stapes footplate, we encountered a stapes gusher. We promptly elevated the head and overlaid some sheets of fascia and cartilage over the stapes footplate to stop the stapes gusher. As a result, there was almost no change in his hearing ability. We then reviewed the CT images carefully and found a slight hypoplastic internal auditory canal. This case underscores the importance of paying attention to predictors of stapes gusher prior to stapes surgery.
