Nose and Nasal Cavity

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Summary

Reducing nasal tip projection in rhinoplasty can be achieved effectively without cartilage division. Dorsal component reduction and caudal trim significantly decrease projection, while alar base resection impacts nasal aesthetics.

Area of Science:

Plastic Surgery
Facial Aesthetics
Rhinoplasty Techniques

Background:

Nasal tip projection is a critical element in rhinoplasty, often requiring modification.
Existing techniques for reducing tip projection, primarily involving lower lateral cartilage manipulation, lack extensive objective efficacy data.

Purpose of the Study:

To analyze a series of rhinoplasties to identify surgical maneuvers that most effectively decrease nasal tip projection.
To evaluate the impact of various techniques on nasal tip projection and overall nasal aesthetics.

Main Methods:

A retrospective review of 125 consecutive rhinoplasties performed by a single surgeon.
Multivariate analysis of preoperative and postoperative photographs to assess changes in nasal projection.
Correlation of specific surgical techniques with observed changes in tip projection.

Main Results:

Dorsal component reduction and caudal trim were significantly associated with decreased nasal tip projection.
Cartilage-splitting techniques were infrequently used (2.4%) and not the primary driver of projection reduction.
Alar base resection influenced nasal aesthetics by altering the alar-cheek junction and overall proportions, not absolute tip position.

Conclusions:

Techniques involving release of soft-tissue attachments and anterior septum modification are often sufficient for reducing nasal tip projection.
Cartilage-dividing techniques are rarely necessary for projection reduction in rhinoplasty.
Alar base resection plays a complex role in nasal aesthetics, affecting projection proportions and balance.
