Nose and Nasal Cavity01:24

Nose and Nasal Cavity

16.7K
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 Airway01:29

Suctioning the Nasopharyngeal Airway

6.4K
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.

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

6.8K
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...

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

5.7K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Tracheostomy Care II: Procedure

2.8K
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Administering Oxygen by Nasal Cannula01:29

Administering Oxygen by Nasal Cannula

5.9K
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,...

    Summary

    This study introduces a new domes crossover technique for rhinoplasty to correct overprojected nasal tips. The method achieved satisfactory nasal tip projection, rotation, volume, and shape in all patients without complications.

    Area of Science:

    • Plastic Surgery
    • Facial Plastic Surgery
    • Rhinoplasty Techniques

    Background:

    • Overprojected nasal tips are a common concern in rhinoplasty.
    • Existing treatment options for nasal tip overprojection have limitations.

    Purpose of the Study:

    • To discuss overprojected nasal tips.
    • To overview current treatment options.
    • To introduce and evaluate a novel nasal tip modification technique.

    Main Methods:

    • A retrospective study of 29 rhinoplasty patients utilizing the domes crossover technique.
    • Patients were classified into three types based on nasal tip overdevelopment.
    • Pre- and post-operative photographs were analyzed using Goode's ratio, nasofacial angle, and lobule-to-columella ratio.
