Sinus augmentation surgery after endoscopic sinus surgery for the treatment of chronic maxillary sinusitis: a case report.

Chronic sinusitis develops when the ostiomeatal complex becomes stenosed by the swelling of the sinus mucosa. Previously, the Caldwell-Luc method was performed for the treatment of chronic sinusitis. But postoperative complications, such as discomfort of the buccal skin and recurrence of sinusitis, frequently occurred after the operation. Today, endoscopic sinus surgery (ESS) has become widely used for the treatment of chronic sinusitis. The features of ESS allow for the restoration of the physical function of the sinus membrane and preservation of the physiological environment of the sinus. Therefore, sinus augmentation surgery can be safely performed at an insufficient alveolar bone height below the maxillary sinus when sinusitis is eliminated by the ESS. This article documents a patient history involving chronic sinusitis that was treated by the ESS therapy before sinus augmentation surgery as a pretreatment for insertion of dental implants.
