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...

Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
Equipment Required

Cranial Bones: Lateral View

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Summary

Maxillary advancement in orthognathic surgery affects facial aesthetics, specifically altering the nasolabial region. This surgery leads to alar base widening, columellar shortening, and nose base lengthening.

Area of Science:

Plastic Surgery
Orthognathic Surgery
Facial Aesthetics

Background:

Facial aesthetics significantly motivate patients seeking orthognathic surgery.
The nasolabial region is crucial for facial aesthetics and orthognathic surgery planning.
Understanding nasolabial changes is key to successful surgical outcomes.

Purpose of the Study:

To investigate modifications in the nasolabial area following maxillary advancement.
To quantify changes in key facial landmarks after orthognathic surgery.

Main Methods:

Study included 42 patients who underwent orthognathic surgery.
Maxillary advancement was performed using Le Fort I osteotomy.
Measurements of nasolabial landmarks were taken pre- and post-surgery.

Main Results:

Alar base widening was observed in patients.
A trend towards columellar length shortening was noted.
The base of the nose showed a lengthening effect.

Conclusions:

Maxillary advancement influences nasolabial aesthetics.
Specific changes include alar base widening, columellar shortening, and nose base lengthening.
These findings aid in planning orthognathic procedures for improved facial balance.
