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...

Area of Science:

Plastic Surgery
Dermatology
Aesthetic Medicine

Background:

Non-surgical rhinoplasty is gaining popularity for nasal augmentation in East Asian populations.
A standardized, anatomy-driven protocol for sequential correction of the Asian nose is currently lacking.

Purpose of the Study:

To evaluate a sequential, layered, anatomy-driven protocol for non-surgical rhinoplasty in East Asian patients.
To assess the safety and efficacy of a hyaluronic acid filler injection technique for nasal tip, dorsum, and glabellar complex augmentation.

Main Methods:

A dual-center retrospective study involving 528 East Asian patients (2020-2024).
Hyaluronic acid filler injected via cannula in a sequence: nasal tip, dorsum, and glabellar triangle.
Outcomes assessed using FACE-Q and 3D facial scanning (MVS-N1) preoperatively and at 9 months.

Main Results:

Significant improvements in nasal length (+2.62 mm), tip projection (+3.69 mm), nasolabial angle (+5.7°), and nasofrontal angle (-9.4°) (p < 0.001).
Marked improvements in patient-reported outcomes: satisfaction (+44.4), social function (+26.2), psychological well-being (+28.1), and reduced distress (-39.4) (p < 0.001).
No vascular complications; 11 cases of transient erythema resolved with conservative measures.

Conclusions:

The sequential 'tip-dorsum-glabella' injection protocol is a clinically feasible approach for non-surgical rhinoplasty in East Asian patients.
The refined cannula-based technique for fibrous septal tip augmentation is associated with low complication rates.
Significant short-term improvements in both anthropometric and patient-reported outcomes were observed.
