Effect of sealing the sinus mucosa perforation with two patching materials : a retrospective multicenter study

Abstract EN

ackground & Objective: Maxillary sinus mucosa perforation (SMP) management is considered to be a challenge for the surgeon during maxillary sinus floor elevation procedures (SFE).

The purpose of this study was to evaluate clinically and radiographically the results of SMP sealing with two patching materials (Biocollagen®, Surgicel®).

Methods & Materials: We retrospectively reviewed a total of 290 sinus floor elevation procedures were performed in four dental clinics in Damascus.

Only 266 of those procedures were included in this study because of sufficient data related to the SMP management and available 1-week postoperative radiographic and clinical information.

Statistical evaluation was performed using Chi-Square tests (P < 0.05).

Results: SMPs being reported in 113 (42%) of the procedures at the time of surgery, of those only 95 perforations were repaired using either Biocollagen® (21%) (completely or partially placed inside the sinus) or Surgicel® (79%) (one- or two-layer).

A total of three moderate SMP managing cases (3%), which were patched with a Biocollagen® membrane was placed totally inside the sinus, were considered failed.

However, there was no statistically significant difference between sealing success and whether the collagen membrane was placed totally or partially inside the sinus (P = 0.73).

Statistically, the success was distributed equally between the four used techniques (P = 0.008).

Conclusions: The results support the clinical use of Biocollagen® and Surgicel® for repairing small and moderate SMPs.

Other factors, other than the clinical success, may be considered in selecting between them.
