Pulley-Stitch: An Innovative Technique for Optimizing the Lateral Crus in Rhinoplasty

Overview

The lateral crus is the side arm of the tip cartilage. When it sits at the wrong angle, the tip loses support and the nostril rim can collapse on breathing in. The authors describe a suture they call the Pulley-Stitch and measured what it does to that angle in a prospective cohort of 42 patients reported to STROBE guidelines.

Sections of note

• Prospective cohort study, 42 patients, all open rhinoplasty.
• The measured angle runs between the lower edge of the medial crus and the front third of the lateral crus.
• Measurements came from photographs at four points: during surgery before the stitch, during surgery after the stitch, and from standardised photographs at 1 month and 12 months.
• Mean angle rose from 18.2 to 26.9 degrees, p < 0.05.
• The authors report the correction was stable at 12 months.
• The abstract reports no complication counts and no comparison group.

What it means for a patient

• The technique is aimed at malposition of the tip cartilage, a known cause of a pinched look and of the nostril rim drawing in on inspiration.
• The reported benefit is a measured change in cartilage angle, not a patient-reported breathing or satisfaction score.
• One group of surgeons, no control arm, and outcomes judged from photographs by the same team.

Why this paper matters

Suture repositioning of the lateral crus competes with strut and rim grafts, which require harvested cartilage. Whether an angle change of this size translates into better breathing or a better long-term shape is not answered here.

Terms

• Lateral crus: the side arm of the lower lateral cartilage, forming the roof of the nostril.
• Medial crus: the inner strut of the same cartilage, running down the middle of the tip.
• Malposition: the lateral crus lying at an abnormal angle, often too vertical.
• External nasal valve: the nostril opening, which can collapse inward on breathing in.
• Cephalic rotation: turning the tip upward.
