Minor Salivary Gland Tumours of Upper Aerodigestive Tract : A Clinicopathological Study

Abstract EN

The aim of this retrospective study of 56 patients with minor salivary gland tumours (MSGTs) of the upper aerodigestive tract is to present demographic features, distribution of tumours as well as methods and results of treatment performed in our institution over a 10-year period.

Of 221 patients with salivary gland tumours, 56 patients with MSGT were selected.

There were 36 female and 20 male patients aged from 8 to 81 years.

Male-to-female ratio was 1 : 2 in the group of benign MSGT and 1 : 1.7 in the group of malignant tumours.

The palate was the most frequent site of MSGT (45.6%), followed by buccal mucosa (19.3%).

Of all MSGTs 63.2% were malignant, and 36.8% were benign.

Adenoid cystic carcinoma was the most common neoplasm (31.6%), followed by pleomorphic adenoma (29.8%).

Surgery was the method of choice in the treatment of patients with MSGT.

Postoperative defects were reconstructed by prosthetic obturators, local flaps, and free radial forearm flap.

Relative survival for patients with malignant MSGT was 88% at three years and 71.5% at five years.

MSGTs are more frequent in females and predominantly affect the palate.

Malignant MSGTs are more common than benign.
