Abstract

The internal nasal valve is the narrowest point in the nasal airway and thus is the controlling point that regulates inspiration flow. The cross-sectional area of the internal nasal valve is approximately 40 to 55 mm, and 40 to 50 percent of inspiratory resistance is attributable to internal nasal valve function. Collapse of one or both internal nasal valves can be a consequence of previous surgery, trauma, aging, or primary weakness of the upper lateral cartilage. In this study, autologous conchal cartilage was used as a splay graft for opening and reconstructing the internal nasal valve. Over 3.5 years, 31 patients (18 female patients and 13 male patients) were operated on using the splay graft. Inclusion criteria were positive Cottle sign and modified Cottle sign. Cause of collapse was previous surgery in 12 patients (38.7 percent), primary weakness in 10 patients (32.3 percent), and nasal trauma in nine patients (29 percent). After 10 to 42 months of follow-up, 80.6 percent of patients had good to excellent (stable) subjective respiratory function. There was no major morbidity or complication after surgery. Six patients complained of broadening in the middle nasal vault.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
