“…12 Cottle's maneuver or external nasal dilator showed similar effects. 16,17 In our results, the lateral nasal suspension elongated the distance from the nostril to the MCA by 12.1%. In separate studies, Cottle's maneuver, external nasal dilation, and spreader grafts did not change the distance.…”

This study was designed to measure the efficacy of a nasal valve suspension technique and determine the adequate traction length without creation of nasofacial fullness in a cadaveric model. Seven fresh frozen cadaveric heads were evaluated. Minimal cross-sectional (MCA) areas were measured with a transient-signal acoustic rhinometer (Ecco Vision; Hood Instruments, Pembroke, MA) before and after suspension. The adequate traction length, which did not cause obvious changes, was determined. Five millimeters of lateral nasal valve traction was determined to be the maximal traction achievable without creating facial fullness. After lateral nasal suspension, average MCA increased by 13.7%. Average distance to the MCA from the nostril changed from 1.57 to 1.76 cm. Postsuspension values were significantly higher than the presuspension values (p < 0.05). Nasal valve suspension with 5 mm of lateral traction has a significant impact on nasal valve area without obvious nasofacial changes.

“…Twenty‐one articles were identified relating to acoustic rhinometry, rhinogram, nasal echogram or NV. The cross‐sectional area of the first notch (CSA1) appears immediately after 0 cm and appears to correspond to the NV, 11–19 the ‘ isthmus nasi ’, 6,20–22 ‘probably’ the ‘ ostium internum ’, 23 an area near the NV, 24 the junction of the nosepiece and the nostril, 25,26 the junction of the nosepiece and the ‘ isthmus nasi ’, 27 the nostril 28 or it may also be artefactual 29,30 (Table 1). The cross‐sectional area of the second notch (CSA2) appears to correspond to the anterior end of the inferior turbinate 6,11–15,17–24,30 or to the NV 25–28,31 (Table 2).…”

“…Some authors have detected changes in the CSA1 and CSA2 by applying an external nasal dilator 18,22 or by Cottle’s maneuver 28 and after using a decongestant. They found a slight increase in the CSA1 and a significant increase in the CSA2 when using an external nasal dilator.…”

A systematic review to assess the anatomical correlates of the notches in acoustic rhinometry

The majority of Acoustic Rhinometry studies affirm that the first notch is the nasal valve and the second is the anterior end of the inferior turbinate. These findings were based on papers that had not studied the anatomical correlation of these notches. Other studies claim that the first notch is the nostril and the second is the nasal valve as a whole. The conclusion that can be drawn concerning anatomic correlation of the first two notches is that there are conflicting opinions about this correlation in the literature and that more studies are needed to provide more convincing data.

“…Values obtained for crosssectional area at three specific points within the nose, minimum cross-sectional area, volume, and resistance were statistically significantly different compared with those obtained for the Sheen technique. The minimum distance obtained for the 13,14 The placement of the upper lateral cartilages cephalad to the septum-spreader complex allows the spreader grafts to function as a fulcrum, thereby widening the angle between the upper lateral cartilages and the septum. This effect is further enhanced by the horizontal mattress sutures that hold the upper lateral cartilages together.…”
