We report a rare presentation of Oncocytoma of the submandibular salivary gland in an young adolescent female who presented with progressive swelling in the left submandibular region since childhood with pain for the past one month. Fine needle aspiration revealed Oncocytoma for which a conventional submandibular excision was done. There are few articles about the rare presentation of submandibular Oncocytoma and literature favors older population for this rarity. This case was unique because of its presentation in a young individual and there were no supporting published articles available till date.

The effect of functional endoscopic sinus surgery (FESS) was evaluated in 20 patients with chronic sinusitis. The physiological function of sinus mucosa and its mucociliary transport mechanism was assessed pre and post operatively in patients undergoing FESS by performing Saccharin clearance test. The effect of functional sinus surgery on nasal mucosa was evaluated using scanning electron microscopy and study of the ultrastructure of cilia in pre and post operative patients and correlation with histopathological examination. The mucociliary transport mechanism of the sinus mucosa improved 6 weeks following surgery. Histopathologically there was evidence of improvement in the ciliary population and decrease in inflammation, ulceration, fibrosis, vascular congestion, edema, squamous cell metaplasia, basement membrane thickening and polyp formation in comparison to the diseased mucosa sampled preoperatively. Scanning electron microscopic examination revealed considerable increase in the ciliary area as well as the orientation of cilia. Subjective improvement 6 weeks following surgery was confirmed by decrease in saccharin test time. This study revealed that FESS is an effective surgical procedure in chronic sinusitis and improves the overall function of the sinuses.
