Conservation of salivary secretion and facial nerve function in partial superficial parotidectomy

Abstract Conventional total superficial parotidectomy (TP) has commonly been used, but partial superficial parotidectomy (PP) offers the possibility of better preserving glandular function and avoiding palsy of the facial nerves. In this study, the extent to which saliva secretion and facial nerve f...

Description
Summary:Abstract Conventional total superficial parotidectomy (TP) has commonly been used, but partial superficial parotidectomy (PP) offers the possibility of better preserving glandular function and avoiding palsy of the facial nerves. In this study, the extent to which saliva secretion and facial nerve function were conserved in patients who received TP vs. PP was compared. Data were collected from patients who received a PP ( n = 163) or a TP ( n = 105) for benign primary tumours in the superficial lobe of the parotid glands between 1995 and 2009 at a single hospital. The incidence of transient facial paralysis was significantly lower in patients who received PP than in those who received TP. Secretory function was preserved for patients with a conserved Stensen's duct, whereas patients in whom the duct had been ligated lost secretory function. Partial superficial parotidectomy reduces the incidence of postoperative facial nerve dysfunction and is conducive to preserving Stensen's duct and saliva secretion.
