SIMUNEK, A; KOPECKA, D  e  CIERNY, M. The use of oxidized regenerated cellulose (Surgicel^®) in closing Schneiderian membrane tears during the sinus lift procedure. West Indian med. j. [online]. 2005, vol.54, n.6, pp. 398-399. ISSN 0043-3144.  http://dx.doi.org/10.1590/S0043-31442005000600012.

During the sinus lift procedure, undesirable perforations of the Schneiderian membrane can occur in up to 58% of cases. Several methods for their closing exist. This article presents a method of covering the perforation with a strip of oxidized regenerated cellulose (Surgicel^®). One or two layers of material swell after being saturated with blood, turning into a gelatinous mass and forming a tight and mechanically resistant seal. This simple method has been successfully tested on 223 perforations of the Schneiderian membrane that occurred over a period of 58 months.
