AIM: Parotid gland is the most common location for salivary gland tumors, more commonly pleomorphic adenoma and Warthin's tumor. Types of parotid surgery include superficial parotidectomy (SP), partial superficial parotidectomy (PSP), total conservative parotidectomy (TCP), enucleation (E), extracapsular dissection (ECD), and are related to different incidence of complications. The choice depends on tumors localization, dimension and histology. The aim was to compare complications rate such as facial and great auricular nerve impairment and Frey syndrome according to type of surgery performed.
MATERIALS AND METHODS: We retrospectively review the management of 116 benign tumors of the parotid gland treated between January 2004 and January 2020 at our Department.
RESULTS: Most frequent complication observed was a GAN deficiency (22.41%), permanent in 13% of cases. Post-operative facial nerve impairment was observed in 19 patients (persistent only in 1 case). Only Frey syndrome (4,31% of cases) seemed to be related to type of surgery (p<0.05) resulting more frequent in the group of patients that underwent "classical" parotidectomy, while facial nerve impairment, even if more frequent in this cases, did not statistically correlated with operative technique (p=0.054).
CONCLUSIONS: Once experience is gained, in order to reduce post-operative morbidity extracapsular dissection is a reliable technique in the management of these neoplasms, even if attention has to be paid particularly in the removal of superficial masses "emerging" from the parenchyma. PSP is an alternative to SP, while CTP has to be reserved to selected cases ot tumors arising in the deep lobe.
