ABSTRACT
Statement of Problem: The most common method for parotid duct anastomosis is suturing. A ductal defect of greater than 1cm may prevent a direct anastomosis
Purpose: The goal of this study was a sialographic evaluation to compare repairing a parotid duct with facial vein graft versus Gore-Tex tub in 19 dogs
Material and Methods: Nineteen dogs were studied in this experimental trial. Extra oral transverse incisions were made in buccal regions bilaterally to expose parotid ducts and a defect [2 cm] was performed in similar areas [right and left]. The right resected duct was repaired with facial vein graft and the left anastomosis was performed by using the Gore- Tex tube microscopically. Sialography was used to evaluate the ductal leakage. Statistical analysis was performed, using SPSS software and McNemar's test
Results: Based on the sialography evaluation; the ductal leakage was seen in five cases [26.31%] on the right side and in seven cases [36.84%] in the left side. Statistical analysis using McNemar's test suggested no statistically significant difference between ductal leakages in right and left parotid ducts [p>/= 0.05]
Conclusion: The results of this study suggest that the efficacies of Gore-Tex tube and vein graft in parotid duct anastomosis are similar, but the use of Gore-Tex tube had a number of advantages, including reduced morbidity of the graft and short operation time
