An overview of cases of parotid gland tumors managed in a teaching hospital, North-west, Nigeria
Objective: Salivary gland tumors are mostly slow
growing and painless. Majorities are located in the
parotid glands and are benign. Treatment of these
parotid tumors may endanger the facial nerve. This
study evaluated the clinical presentation and
management of parotid gland tumors in Kaduna, Northwest,
Methods: This was a retrospective study of patients
that were treated for parotid gland tumors at the
Maxillofacial Unit of Barau Dikko Teaching Hospital,
Kaduna, North-west, Nigeria over a period of 13years
(January 2008 to December, 2020). Patients’ records
were analyzed for age, sex, clinical presentation,
investigations, surgical management, histological
diagnosis and outcome of treatment.
Results: A total of 55 patients with parotid gland tumors
were seen. Age range was 12 - 75 years with a mean of
45.5 (SD± 0.7) years. The male: female ratio was found
to be 1.1: 1. Pleomorphic adenoma was the commonest
tumour (n=28, 50.9%). Four (7.3%) patients who had
been on antiretroviral medications were seen with
massive tumors. Superficial parotidectomy was the
commonest surgical procedure carried out in these
patients. Patients with malignancies were referred for
post-surgical radiotherapy. High early recurrences were
noticed in patients who were retroviral positive.
Conclusion: Pleomorphic adenoma was the
commonest tumors treated and superficial
parotidectomy was the commonest surgical procedure
performed for the treatment of parotid gland tumors.
Post-operative radiotherapy as an adjunct was carried
out in cases with diagnosis of malignant lesions.
