Abstract

Objectives: The aim of the study was to compare rhinomanometry, acoustic rhinometry and subjective estimation of the nasal obstruction before and after septoplasty, and to evaluate the long-term results of septal surgery.

Design: Prospective long-term follow up, before and after septoplasty

Setting: University tertiary-care hospital, referral centre

Participants: The study included 30 adult patients who were operated on because of septal deviation.

Main outcome measures: Preoperatively, acoustic rhinometry and active anterior rhinomanometry were performed on each subject after decongestion of the nose. A visual analogue scale for unilateral nasal obstruction was filled in by the patients. The measurements were repeated both six months and ten years postoperatively.

Results: A significant change in acoustic values was found during the long-term follow up of ten years. The mean minimal cross-sectional area on the more obstructive side was 0.35 cm2 preoperatively. Six months after operation it was 0.52 cm2, and ten years after operation 0.68 cm2. The mean resistance fell from preoperative 1.16 Pa/ml/s to 0.41 Pa/ml/s during the first six months, but rose again to 1.21 Pa/ml/s after ten years. No significant change was found between preoperative and postoperative values in VAS.

Conclusions: We found an increase in acoustic values, but an increase in nasal resistance in the long-term follow-up. Other factors than nasal area may have an impact on nasal resistance and the feeling of nasal obstruction. The small size on the sample interfered with the results.
