COMPARATIVE STUDIES ON DIFFERENT METHODS OF SURGICAL CORRECTION OF EXPERIMENTALLY INDUCED PAROTID DUCT FISTULA

Parotid duct fistulae were experimentally induced in 14 donkeys. Animals were divided into four groups where different methods of surgical correc tions namely freshening and suturing, segmental reconstruction, duct ligation and distruction of the function of the parotid salivary gland with duct ligation were performed.
Healing of the fistulae was accomplished by first intention in 2 out of 3 animals of the first group. Complete healing was observed in group two with preservation of the function of the gland. In group three
signs of gland atrophy were not detected in all animals 60 days after duct ligation. Injection of lugol's solution with duct ligation leads to complete gland atrophy within 2 months in group 4. In conclusion, segmental reconstruction of the parotid salivary duct was recommended when the function of the gland is aimed to be preser ved. When destruction of the function of the gland is suggested, ligation of the duct after injection of irritant material was recommended.
