RESUMO
RESUMO As neoplasias das glândulas salivares são relativamente raras, compreendendo cerca de 1% das neoplasias de todo corpo, com incidência de 1/100.000 habitantes por ano. As neoplasias benignas predominam sobre as malignas. O prognóstico depende muito do tipo histológico, grau de diferenciação, localização, infiltração de tecidos vizinhos e da presença de metástases regionais ou a distância. O principal tratamento ainda é a cirurgia, com os seus desafios e dificuldades, devido aos ramos do nervo facial nas glândulas salivares maiores, seguido de radioterapia e em casos selecionados quimioterapia adjuvante. O objetivo desta revisão é fornecer ao leitor uma abordagem histórica sobre o tratamento das doenças das glândulas salivares, com especial atenção às doenças da glândula parótida assim como peculiaridades associadas aqueles que as estudaram ao longo da história.
ABSTRACT Salivary gland neoplasms are a relatively uncommon disease, with nearly one case per 100.000 adults estimated per year and an overall incidence of 1% of all neoplasms. The benign neoplasms are majority and the prognosis depends on the histologic type, grade, localization, soft tissue infiltration, regional and distant metastasis. The main treatment is surgery with caution to facial nerve in the major salivary glands, followed by radiotherapy and chemotherapy in selected cases. The objective of this review is to provide the lector an historic approach about salivary gland diseases treatment, with special attention to the parotid neoplasms and its peculiarities associated to those who studied these glands in their history course.

PURPOSE The parotidectomy technique still has an elevated paresis and paralysis index, lowering patient life's quality. The correct identification of the facial nerve can prevent nerve damage. Fluorescent dye identifies nerves in experimental studies but only few articles focused its use on facial nerve study in parotidectomies. We aimed to stain the rat facial nerve with fluorescent dye to facilitate visualization and dissection in order to prevent injuries. METHODS Forty adult male Wistar rats were submitted to facial injection of saline solution (Gsf-control group, 10) or fluorescent dye solution (Gdye group, 30) followed by parotidectomy preserving the facial nerve, measuring the time for localization and facility of localization (LocTime and LFN). Nerve function was assessed using the Vibrissae Movements (PMV) and Eyelid Closure Motion (PFP) scores. RESULTS Nerve localization was faster in Gdye group, with 83% Easy LFN rate. The Gdye group presented with low nerve injury degree and better PMV and PFP scores, with high sensitivity and accuracy. CONCLUSIONS This experimental method of facial nerve fluorescence was effective for intraoperative nerve visualization, identification and preservation. The technique may be used in future facial nerve studies, translated to humans, contributing to the optimization of parotid surgery in the near future.
