Classification of Salivary Gland Diseases among Yemenis: (A Prospective Hospital-Based study) | Biomed grid

Objective: This study aims to classification of salivary gland diseases among Yemenis to established data base, determine the common disease, common site and the relation of these disease to the age and gender. Material and Methods: The present study designed as a prospective descriptive hospital –based study carried out at Al-gomhori –Teaching Hospital in Sana'a. All patients attending to the department of oral and maxillofacial surgery and to the consultant unit of the head and neck surgery complain of salivary gland disease were examination. Data were collected from patient history (using a questionnaire form), clinical examination of patients, radiographs examination and from the histopathology results of the biopsies. Biopsy result used to confirm the diagnosis. Results: A total of 140 cases of salivary gland diseases were studied,64 cases (45.7%) were males, and 76 cases (54.3%) were females, male to female ratio was 0.8-1. The age of patients was ranged from 3 to 82 years, with mean age for both gender of 40. 09±21.149. The majority of patients (79%) were over the age of 20 years. The most common disease of salivary glands tumor was salivary gland tumor, accounting 43.6%, followed by cystic lesions 20.7% and sialolithiases (20.0%). The less common salivary gland diseases were sialadenitis and sialadenosis, accounting,12.9% and 2.9% respectively. Sqaumous cell carcinoma was the most common types of salivary gland malignancy, accounting 50. 0%. Pleomorphic adenoma was the most common types of benign tumors accounting,78.3%. Major salivary glands were the most involving site by both tumors. Rhanula was the most common type of salivary gland cyst accounting, 75.9%, usually found on the sublingual glands. Sialolithiases, usually found on the major salivary glands, 89.3% of this disease were located on the submandibular gland. Sialadenitis, frequently caused by bacterial and viral infections, 77% of them were bacterial sialadenitis and 22.2% were viral sialadenitis. Bacterial sialadenitis, commonly located on the submandibular gland, whereas, viral sialadenitis restricted to the parotid glands. Conclusion: One hundred and forty cases of salivary gland disease among Yemenis were studied,64 cases (45.7%) were males, and 76 cases (54.3%) were females, male to female ratio was 0.8-1. The age of patients was ranged from 3 to 82 years, with mean age for both gender of 40. 09±21.149. The majority of patients (79%) were over the age of 20 years. Salivary glands tumor was the most common salivary gland disease, accounting 43.6%, followed by the salivary gland cyst and sialolithiases accounting, 20.7% and 20.0% respectively. Sqaumous cell was the most common type of salivary gland malignancies accounting 50. 0%. Pleomorphic adenoma was the most common type of benign tumors accounting 78. 3%. Both salivary gland tumors commonly located on the major salivary glands. Rhanula was the most common type of salivary gland cyst, accounting 75.9%,usually located on the sublingual gland. Sialolithiases, accounting 20.0% of all salivary gland disease, 89.3% of this disease were located on the submandibular gland. The less common types of salivary gland disease were sialadenitis and Sialosis, accounting 12.09% and 2.9% respectively
