Buffered hypertonic saline nasal irrigation significantly improves nasal mucociliary transit times. Buffered normal saline nasal irrigation showed no effect on these important sinonasal functions.

Area of Science:

  • Otolaryngology
  • Rhinology
  • Medical Physiology

Background:

  • Nasal irrigations are a long-standing practice lacking robust scientific validation.
  • The senior author has clinically utilized buffered hypertonic saline nasal irrigation for sinonasal conditions for a decade.

Purpose of the Study:

  • To scientifically evaluate the efficacy of buffered normal saline versus buffered hypertonic saline nasal irrigation on sinonasal mucociliary function.

Main Methods:

  • A crossover study design was employed using healthy volunteers.
  • Saccharin clearance tests were used to measure mucociliary transit times before and after nasal irrigation with either buffered normal saline or buffered hypertonic saline.

Main Results:

  • Buffered hypertonic saline nasal irrigation demonstrated a significant improvement in mucociliary transit times.

  • Buffered normal saline nasal irrigation did not yield any significant changes in mucociliary transit times.

    • Conclusions:

    • Buffered hypertonic saline nasal irrigation is an effective method for enhancing nasal mucociliary clearance.
    • This study provides scientific evidence supporting the use of hypertonic saline for improving sinonasal function.
