Clinical application of the polyvinylalcohol (PVA) sponge in the extirpation of maxillary bone cyst is presented.
PVA sponge material is now widely employed industrial products, household utensils, and medical instruments. PVA sponge is highly hydrophilic and water-absorbant due to its continuous microporous structure. Because of this, we considered that PVA sponge might possess both tamponade and drainage functions. Thus, we used PVA sponge in the extirpation of maxillay bone cyst when radical surgery of the maxillary sinuses was simultaneously performed.
PVA sponge was introduced into the antral cavity and brought out through the nose. PVA sponge was usually removed on the second day after operation.
The result was satisfactory: little pain and bleeding was noted when the PVA sponge was removed. In addition, postoperative buccal swelling was considerably reduced.
