Nasal Valve Collapse
Open accessAbstract
A Figure J.A : Saddle-nose deformity is corrected via a single dorsal onlay spreader graft procedure.B: The operation begills as a typical open septorhinoplasty.C: The on lay spreader graft is placed centrally over the septum and then sutured to each upper lateral cartilage.

Internal nasal valve is the narrowest part of the nasal airway and its cross-sectional area is determined by the angle formed between the caudal part of the upper lateral cartilage and nasal septal cartilage.
“The internal nasal valve is the narrowest part of the nasal airway and its cross-sectional area is determined by the angle formed between the caudal part of the upper lateral cartilage and nasal septal cartilage [3, 4].”
From The value of spreader grafts in rhinoplasty: a critical review (2012) · cites this paper as [3]
The Abstract says the internal nasal valve’s cross-sectional area is determined by the angle where the upper lateral cartilage connects with the septal cartilage. It does not state that the internal nasal valve is the narrowest part of the nasal airway or specify the caudal part of the upper lateral cartilage. (LLM, conf=0.86)
Experimental — accuracy not yet measuredNasal valve collapse occurs when the narrowest part becomes weak and narrower than 9°.
“Nasal valve collapse occurs when this narrowest part becomes weak and narrower than 9° [3].”
From The value of spreader grafts in rhinoplasty: a critical review (2012) · cites this paper as [3]
The passage labeled Abstract says the internal nasal valve’s cross-sectional area decreases as its angle narrows, and describes collapse when the angle is less than 10° to 15°. It does not give a 9° threshold or say that the narrowest part must become weak. (LLM, conf=0.88)
Experimental — accuracy not yet measured

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.
