Parotid neoplasms: diagnosis, treatment, and intraparotid facial nerve anatomy

Abstract

The demographics of parotid neoplasms in different populations have been reported by various centres. In this investigation, we reviewed retrospectively all the in-patient and out-patient charts and records of 108 patients who were diagnosed with parotid neoplasms and received parotidectomies in our department from 1 January 1993 to 15 April 2000. Patient age, gender, tumour pathology, fine-needle aspiration cytology results, and the intraparotid anatomy of the facial nerve were noted. We showed that despite the difference between our Taiwanese and previously studied patient populations, both populations had a similar distribution, diagnosis and treatment of parotid neoplasms, although the incidence of parotid tuberculosis was higher in our patient group. In addition, the facial nerve anatomy within the parotid gland had three main branching patterns in the upper and lower division.

An Anatomic Study of the Facial Nerve Trunk and Branching Pattern in an African Population

“…Several authors have reported the possibilities of trifurcation, quadrifurcation, or even a plexiform branching pattern of the FN trunk 2,5, 13,15,20,23,30 -7,9,15,19,20,30 Trifurcation in the present study was observed in 20% of the population like other studies from Turkey reporting trifurcation of 18.6, 18.8, and 18%, respectively. 6,31,32 Khaliq et al in another study from Indian reported single trunk of FN in 95 and 8.57% of bifurcation, while Rana et al reported single trunk (2%) and trifurcation (3%).…”

“…4 Several studies have demonstrated variations in the branching patterns of the FN, bifurcation and trifurcation of the main trunk, reanastomosis, looping patterns, and morphometric variations in relation to surgical landmarks. 2,5- 14 •Various classification systems of the FN have been used by different authors dating from 1945 by McCormack et al, 12 Dargent and Duroux (1946), 13 Davis et al (1946), 5 Baker and Conley (1979), 14 Katz and Catalano (1987), 9 Kopuz et al (1994), 6 Tsai et al (2002), 15 and Kwak et al (2004) 2 to mention a few. 2,5,6,9,[12][13][14][15] Racial differences have been noted regarding the branching in FN in some studies.…”

Adenoma pleomórfico de parótida: aspectos clínicos, diagnósticos e terapêuticos

“…O adenoma pleomórfico é a neoplasia benigna mais comum da glândula parótida, ocorrendo predominantemente no sexo feminino, com uma relação em torno de 1,5:1, e com média etária que pode variar de 36 anos a 45,7 anos 6,8 . Observamos uma ocorrência três vezes maior no sexo feminino, quando comparamos com o sexo masculino, e ocorrendo predominantemente na 5 a década de vida, em torno dos 48,7 anos.…”

“…Os exames de imagem, particularmente a ultrassonografia e a tomografia computadorizada, não são essenciais e podem ser realizados em casos selecionados para planejar o tratamento 3 . A biópsia aspirativa com agulha fina (BAAF) é outra modalidade diagnóstica que pode ser utilizada no sentido de determinar se o tumor é benigno ou maligno, no entanto não serve para definir a conduta terapêutica 8 . O diagnóstico definitivo de adenoma pleomórfico é realizado pelo exame histopatológico em cortes de parafina, a partir de uma parotidectomia com identificação e preservação do nervo facial 6 .…”

Tumor parotídeo gigante. Reporte de caso clínico

“…Su proceso de crecimiento es lento y unilateral, y su sintomatología clínica es muy leve. Por lo general se compromete el lóbulo superficial de la glándula parótida (2). El tratamiento es quirúrgico, con resección completa del lóbulo superficial, y profundo, si está comprometido.…”
