Paranasal sinus cancers comprise about 0.3% of all cancers and 80% of these lesions arise in the maxillary sinus. A masquerading primary sinus tumour represents a therapeutic challenge as most patients with maxillary antrum cancer are diagnosed with advanced disease. However, distant metastases rarely occur. We examined the clinical outcome of patients with antrum neoplasms. Medical records were obtained for all patients diagnosed with a sinus malignancy between July 2009 and January 2014. During this period, 41 patients with maxillary tumours were treated, among which 9 patients received a maxillectomy. There were 21 male and 20 female patients. All patients underwent computed tomography or magnetic resonance imaging. The most common complications were postoperative epistaxis and swallowing difficulty. The treatment of maxillary antrum tumours is complicated and needs advancements to improve early presentation, timely diagnosis, and better management outcomes.

Objective Sialolithiasis, the most common disease of the salivary gland, is characterized by calculi in gland and its duct. While most salivary calculi are small in size, giant calculi with diameters spanning several centimeters are also reported occasionally. The surgical removal of recurrent submandibular sialoliths. Results This study presents of recurrent submandibular sialadenitis/sialadenosis and the characteristic signs and symptoms included pain, recurrent swelling, and discharge of pus, fibrotic and atrophic condition of the gland followed by cessation of secretary functions. Radiological examinations revealed large and irregular structures in the reported cases. Conclusion We have described the characteristic clinical and radiological features, diagnosis and treatment approach for submandibular salivary gland sialadenitis/sialadenosis.
