Double-Tunnel Creation in Mucoperichondrial-Mucoperiosteal Septal Flap to Preserve the Sagittal Stability of Dorsal Components in Rhinoplasty

Overview

Removing a hump in structural rhinoplasty separates the upper lateral cartilages from the septum, so the side walls can drift inward and backward and spoil the dorsal aesthetic lines. The Iranian authors say this loss of control drove the move toward dorsal preservation. Their answer keeps structural hump removal but creates a double tunnel within the mucoperichondrial-mucoperiosteal flap to control the vertical position of the dorsal components. No outcome figures are given.

Sections of note

• The problem addressed: medial and posterior displacement of the lateral nasal walls after hump resection.
• The method: a double tunnel within the septal lining flap to control vertical positioning of dorsal components.
• Applied in over 2,000 cases with "favourable outcomes" in preserving mid-vault stability.
• Level of Evidence IV.

What it means for a patient

• This is a structural (hump-removal) technique intended to deliver the mid-vault stability claimed for preservation surgery.
• The claim rests on a very large but undocumented experience; the abstract gives no measurements or complication rates.
• It is a surgeon-facing technical idea rather than evidence of better results.

Why this paper matters

It represents the structural camp's response to preservation rhinoplasty's central argument. Limits: no data, no controls, no follow-up reported.

Terms

• Upper lateral cartilages (ULCs): the paired cartilages forming the middle third of the bridge.
• Mucoperichondrium / mucoperiosteum: the lining layers over septal cartilage and bone.
• Dorsal aesthetic lines: the brow-to-tip highlight lines on the bridge.
• Mid-vault: the cartilaginous middle third of the nose.
• Sagittal: the front-to-back plane.
