Alcohol abuse, which can impair clearance of pathogens and debris from the airway, is associated with an increase in complications and a higher mortality rate during the progression of pneumonia. With prolonged alcohol exposure, mucociliary clearance (MCC), which depends on the coordinated beating of cilia, is dysfunctional. Effective MCC relies on cAMP-dependent protein kinase (PKA) activation of ciliary beat frequency (CBF). PKA activation and stimulation of CBF are blunted with chronic exposure to alcohol. This phenomenon is known as alcohol-induced ciliary dysfunction (AICD). Previous studies have shown that concomitant feeding of mice with alcohol and antioxidants prevents AICD, suggesting a …
Evaluation Of Upper Airway Changes Following Surgical Removal Of The Adenoids Using 3-D Cone Beam Ct, Christopher C. Schultz
Evaluation Of Upper Airway Changes Following Surgical Removal Of The Adenoids Using 3-D Cone Beam Ct, Christopher C. Schultz
Theses & Dissertations
Purpose: The purpose of this study was to evaluate the changes in volume, cross-sectional area and depth of the upper airway following the surgical removal of the adenoids.
Materials and Methods: 16 patients were diagnosed with hypertrophic adenoids and referred for surgical removal. Pre-surgical and post-surgical CBCT scans were taken on each patient. Volume measurements of the total airway, oropharynx and nasopharynx were recorded. In addition, cross-sectional areas and airway depths at the posterior nasal spine (PNS) and cervical vertebrae 2 were recorded. 15 patients diagnosed with no or mild adenoid hypertrophy were treated as the control group. The controls …
