[Treatment tactics for patients with retention cysts, odontogenic cysts, mucocele and other pathologies of the maxillary sinuses as preparation for a sinus lift].

Retention cysts do not need to be removed as a preoperative preparation for sinus lifting. In the case of large sizes and difficulty in peeling the Schneider membrane, retention cysts are removed by a dental surgeon during antral augmentation as one of the stages of the operation. In such pathologies as odontogenic cyst, acute and chronic sinusitis, aspergillosis, mucocele, interdisciplinary interaction of ENT doctor and dentist is necessary. Differential diagnosis of maxillary snus pathology is carried out on the basis of clinical data and a picture of cone-beam computed tomography.
