The Blocking Points: The Keys to Consistent Success in Preservation Rhinoplasty

Overview

Dorsal preservation keeps the middle of the nose intact and changes appearance by altering the bony pyramid and the septum beneath. Its distinctive failure mode is hump recurrence. The authors attribute this to blocking points, tissues under tension that either stop the bridge from going down during surgery or push it back up to its original convexity over the following months.

Sections of note

• Article type: technique and anatomy article. No patient numbers, recurrence rates or follow up data are reported.
• Five blocking points had previously been described; the authors add two more for a total of seven.
• The seven are: the cartilaginous septum, the perpendicular plate of the ethmoid, the lateral osteotomy site, the Webster triangle, the internal mucoperiosteum of the maxillary bone, the medial canthal ligament, and the lateral keystone area.
• Stated requirement: the surgeon must know which points matter for the technique chosen and address them methodically. No data on how often each point causes recurrence is given.

What it means for a patient

• Hump recurrence is the recognized weakness of preservation rhinoplasty, and this article explains why it happens mechanically.
• The bridge does not stay down simply because it was pushed down. Surrounding attachments pull it back unless they are released.
• The abstract carries no findings. It reports no recurrence rates and does not show that addressing all seven points prevents recurrence.
• Two of the seven points are newly proposed here and have not been independently confirmed.

Why this paper matters

Preservation rhinoplasty spread quickly, and audits of published photographs have found residual and recurrent humps as its most common flaw. Naming the anatomical causes turns a vague failure into a checklist. Whether following that checklist actually lowers recurrence rates is untested.

Terms

• Dorsal preservation: lowering the bridge while keeping its natural surface intact.
• Midvault: the middle third of the nose, formed by the upper lateral cartilages and septum.
• Perpendicular plate of the ethmoid: the thin bone forming the upper rear part of the septum.
• Webster triangle: a small triangle of bone at the base of the nose near the nostril.
• Mucoperiosteum: the lining tissue attached to the surface of bone.
• Medial canthal ligament: the ligament anchoring the inner corner of the eyelids to the nasal bone.
