Nose and Nasal Cavity01:24

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...
Epistaxis01:30

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 View01:27

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...
Suctioning the Nasopharyngeal Airway01:29

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.

Anatomy of Respiratory System I: Upper Respiratory Tract01:29

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.

Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery
  • Otolaryngology

Background:

  • Nasal internal lining reconstruction is crucial for successful outcomes.
  • Existing methods often have drawbacks like limited surface area, functional compromise, or donor site issues.

Observation:

  • A reliable and technically facile technique for nasal reconstruction is presented.
  • This involves creating a bilaminated forehead flap using in situ split-thickness skin grafting.

Findings:

  • The bilaminated forehead flap allows for the reconstruction of large internal surface areas.
  • This technique provides dependable reconstruction in subsequent surgical steps.

Implications:

  • This method offers a solution to the limitations of current nasal reconstruction techniques.
  • It enables surgeons to reconstruct extensive nasal lining defects with improved outcomes.
