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...

Anatomy of Respiratory System I: Upper Respiratory Tract

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.

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

Administering Oxygen by Nasal Cannula

Administering Oxygen by Nasal Cannula

Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils, connected...

Epistaxis

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

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...

Area of Science:

Plastic Surgery
Anatomy
Facial Aesthetics

Background:

The nasal tip is a complex area in rhinoplasty, presenting diagnostic and treatment challenges.
Existing anatomical models may not fully capture the nuances of nasal tip aesthetics and function.

Purpose of the Study:

To introduce and describe the M-arch model for understanding nasal tip anatomy.
To provide a framework for surgical planning in rhinoplasty focused on the nasal tip.

Main Methods:

Presentation of the M-arch anatomical concept.
Description of surgical techniques (suture, incisional, excisional, grafting) applied to the M-arch.
Illustration of representative surgical outcomes.

Main Results:

The M-arch model provides a basis for establishing ideal nasal length, projection, and rotation.
Graduated maneuvers allow for refinement of the M-arch, lobule, and nasal base soft tissues.
The model facilitates a systematic approach to nasal tip surgery.

Conclusions:

The M-arch model offers a novel conceptual framework for nasal tip analysis and surgical treatment in rhinoplasty.
This model aids surgeons in achieving predictable aesthetic and functional outcomes for the nasal tip.
