[Endoscopic maxillary sinusotomy]

Endoscopic maxillary sinusotomy (EMS) was performed in 14 patients with chronic inflammation of the maxillary sinus. This technique provides a visual control of the operative field both on the side of the nasal cavity and on the side of the maxillary sinus; accurate fenestration of the maxillary sinus through the lower nasal passage; on-demand widening of the natural maxillary orifice; adequate orientation of the surgeon in selecting the direction of the resection of the maxillary medial wall raising the effectiveness of the operation and reducing the risk of intraoperative complications.
