Abstract
The laterality in nasal resistance was studied by rhinomanometry. The left-right ratio of nasal resistance was 1.3±0.3 for healthy controls. In patients who underwent intranasal operation, it was 1.8±0.7 before and 1.2±0.2 after the operation in 14 patients with septal deviation, 1.9±0.9 before and 1.3±0.4 after the operation in 13 patients with septal deviation complicated by hypertrophic rhinitis, 1.6±0.4 before and 1.3±0.3 after the operation in 15 patients with chronic sinusitis, and 1.6±0.4 before and 1.3±0.3 after the operation in 16 patients with nasal allergy. The laterality was large in the patients before the operation but became near to that of healthy controls after the operation.
