The effect of COVID-19 on nasal mucociliary clearance.

Background: The impacts of coronavirus disease-2019 (COVID-19) on nasal mucociliary clearance (MCC) have shown conflicting results.

Objectives: The aim of this study was to determine whether COVID-19 infections affect nasal mucociliary activity using the saccharin test to measure nasal MCC time.

Material And Methods: This prospective comparative investigation included 25 patients with COVID-19 infection and 25 healthy controls.

A Rare Cause of Dysphagia: Giant Lipoma in Parapharyngeal Space.

Background: Parapharyngeal area is one of the most complex areas of head and neck anatomy. Tumors of the parapharyngeal region are very rare among head and neck tumors. Lipomas also constitute a tiny proportion of parapharyngeal tumors so parapharyngeal area lipomas are very rare in the literature.
