Seabrook's operation is done for:
|A||Parotid duct fistula|
• Internal fistula opens inside the mouth and doesn't give rise to symptoms
• External fistula: gland fistula or duct fistula
• Rupture of parotid abscess
• Inadvertent incision during drainage of parotid abscess?
• Penetrating injury
• After superficial parotidectomy
• When the external fistula is connected to the gland, external opening is pinpoint, though discharge is present for several months, usually closes spontaneously.
• When external fistula is connected with major duct, there is outpouring of parotid secretions onto cheek during meals with excoriation of surrounding skin
• Sialography or sialogram
• Newman and Seabrook’s operation (in cases of fistula connected with main duct, this operation reconstructs the duct)
