Abstract
Introduction and objectives

Salivary gland tumours account for 3% of head and neck tumours. The aim of this study is to analyze our series of tumours of the salivary glands requiring surgical treatment at our centre from 2004 to 2007.

Material and methods

This study is a retrospective review of 49 patients diagnosed as having tumours of the major and minor salivary glands or ectopic salivary tumours, and surgically treated at our hospital between 2004 and 2007. We reviewed their clinical characteristics, imaging findings, fine-needle cytology results, surgical charts (sub-maxillectomies, parotidectomies, palatal tumour excisions, and cervicotomies), final pathology findings, and course with at least 1 year follow-up.

Results

Forty-nine salivary tumours were treated, including 43 parotid tumours (87%), 3 submandibular tumours (6%), 1 palatal tumour (2%), and 2 ectopic tumours (4%). Sixteen percent of the tumours were malignant. Fine-needle cytology sensitivity was 40%, whereas specificity was 100%. Out of 43 parotidectomies, 40 (93%) were primary parotidectomies, and 3 were review parotidectomies. Most parotidectomies (81%) were superficial or partial and 8 (19%) were total. Parotidectomies complications are similar to those described previously in the literature: permanent facial palsy in superficial or partial parotidectomy (5%), wound dehiscence or necrosis (13%), post-operative bleeding (4%), fever or wound infection (7%), sialoceles (44%) and Frey's syndrome (2%).

Conclusions

Parotid tumours are the most common salivary gland tumours. Most of them are benign, but Warthin's tumour is more frequent than usual in our series. Early and late complications from parotidectomy are uncommon, although sialocele is a common transitory complication in our series.

Resumen
Introducción y objetivos

Los tumores derivados del tejido salival son el 3% de los tumores de cabeza y cuello. El objetivo de este estudio es analizar una serie de tumores derivados de tejido salival que han requerido tratamiento quirúrgico en nuestro hospital en el periodo 2004–2007.

Material y método

Revisión retrospectiva de 49 tumores derivados de glándulas salivales mayores o menores o de estirpe salival de localización ectópica. Se analizan datos relativos a la historia clínica, pruebas complementarias, datos quirúrgicos (submaxilectomías, parotidectomías y otras intervenciones), anatomopatológicos y de evolución del paciente, con un seguimiento mínimo de 1 año.

Resultados

De los 49 tumores salivales, 43 (87%) eran parotídeos; 3 (6%), submaxilares; uno en mucosa oral palatina, y 2 ectópicos cervicales. El 16% de los tumores fueron malignos. La punción aspirativa con aguja fina tuvo una sensibilidad del 40% y una especificidad del 100%. De las parotidectomías, 40 (93%) fueron parotidectomías primarias, y 3 (7%), revisiones de parotidectomías; en 35 (81%) casos fueron parotidectomías superficiales o parciales, y en 8 (19%) fueron totales. Las complicaciones posquirúrgicas en las parotidectomías fueron similares a las descritas en la literatura: parálisis facial permanente tras parotidectomía superficial (5%), necrosis o dehiscencia de herida quirúrgica (13%), hemorragia postoperatoria (4%), fiebre o sobreinfección de la herida (7%), sialoceles transitorios (44%) y síndrome de Frey (2%).

Conclusiones

Los tumores parotídeos son los más frecuentes, siendo en su mayoría benignos. En nuestra serie el tumor de Whartin es más frecuente que en otras series. Las complicaciones precoces y tardías de las parotidectomías son poco habituales, aunque en nuestra serie el sialocele es una complicación transitoria frecuente.
