Polyglycolic acid (PGA) sheet is a bioabsorbable suture reinforcement consisting of polyglycolide, made of nonwoven fabric with some elasticity. It has been used for strengthening tissue defects or suturing together with fibrin glue in thoracic surgery and gastroenterological surgery. Recently, its application to oral and maxillofacial surgery has been reported. We clinico-statistically evaluated prognostic factors (operation site, excised area, fasting period, attachment days of PGA sheet) in 20 oral surgery patients (20 sites) followed by a technique of covering the wound with a PGA sheet and fibrin glue spray, between September 2010 and September 2011 in our department. There were no significant correlations between fasting period and attachment days of the PGA sheet, or between the excised area and attachment days of the PGA sheet. There were significant differences (p < 0.01) between the operation site and attachment days of the PGA sheet. As a result, the fasting period after the operation was not involved in early detachment of the PGA sheet. To prevent early detachment of the PGA sheet, we considered the attachment position and devised a way of suturing the PGA sheet margin after the sheet was attached to the region not supported by bone. In oral surgery for such patients, appropriate steps are suggested with due consideration for the amount of tissue loss depending on the operation.
