Primary Rhinoplasty Combined with Pyriform Aperture Augmentation in Asians

Jianfang Z, Yang A, Dong L.

What this paper says

A technique article describing a purpose designed implant to build up the bony opening around the nose in Asian patients with a hollow midface, used in three combinations depending on how pronounced the hollowing is.

Overview

The authors set out to develop a method of augmenting the pyriform aperture, the bony opening at the front of the nasal cavity, suitable for Asian patients with midface concavity. They designed a new prosthesis for that purpose and describe three surgical schemes depending on how pronounced the concavity is.

Sections of note

Technique article; the abstract reports no patient numbers, no outcomes, no complication rates and no follow up.
A novel prosthesis was designed to perform the augmentation.
The first scheme is simple implantation around the pyriform aperture.
The second combines implantation around the aperture with augmentation rhinoplasty performed at the same time.
The third combines implantation around the aperture with a nasal extension technique.
The stated result is substantial improvement in the aesthetic relationship between the nose and the surrounding face.
The technique is stated to suit comprehensive rhinoplasty in Asian patients with midface concavity.

What it means for a patient

The pyriform aperture is the bony rim the base of the nose sits on, and building it up changes the foundation rather than the nose alone.
Which scheme is used depends on how hollow the midface is.
No results, complication rates or patient numbers are reported.
The implant is an artificial material placed against bone, which carries the general risks of implants.

Why this paper matters

A nose that projects poorly may sit on a recessed bony base, in which case treating only the nose leaves the underlying cause. This article proposes addressing that base directly. It supplies no evidence about how the implants perform.

Terms

Pyriform aperture: the pear shaped bony opening at the front of the nasal cavity.
Midface concavity: hollowing of the middle of the face beneath the eyes and around the nose.
Prosthesis: a manufactured implant placed to restore or add shape.
Augmentation rhinoplasty: surgery that builds the nose up rather than reducing it.
Nasal extension technique: lengthening the nose by extending its framework forward.

From the abstract

“To explore a pyriform aperture augmentation method that is suitable for Asian patients with mid-face concavity, we designed a novel prosthesis to perform pyriform aperture augmentation. Three different rhinoplasty schemes are designed according to the degree of mid-face concavity: (1) simple implantation around the…”
