Chronic Pharyngitis01:23

Chronic Pharyngitis

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
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.
Equipment Required
Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
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.
Tonsillitis II: Management01:26

Tonsillitis II: Management

This lesson will focus on the different treatment options for managing tonsillitis, which typically depend on the cause and severity.

Summary

Adenoidectomy can cause temporary velopharyngeal insufficiency and hypernasality in children. However, most children recover fully, with no evidence of long-term effects on velopharyngeal function.

Area of Science:

  • Otolaryngology
  • Pediatric Surgery
  • Speech Pathology

Context:

  • Adenoidectomy is a common surgical procedure in children.
  • Velopharyngeal closure is crucial for speech and swallowing.
  • Potential effects of adenoidectomy on velopharyngeal function require investigation.

Purpose:

  • To evaluate the immediate and sustained impact of adenoidectomy on velopharyngeal closure.
  • To assess changes in speech characteristics and velopharyngeal function post-adenoidectomy.

Summary:

  • A study involving 31 children undergoing adenoidectomy assessed velopharyngeal function pre- and post-surgery.
  • Results indicated transient velopharyngeal insufficiency and hypernasality in most children within the first week, with some cases persisting up to 3 months.
  • Computerized phonography revealed early speech alterations, including incomplete consonants and nasalization, with a decrease in F3 values for the /i:/ vowel.

Impact:

  • Velopharyngeal insufficiency following adenoidectomy is typically temporary in pediatric patients.
  • The study found no evidence of long-term adverse effects on velopharyngeal function after adenoidectomy.
  • Findings support the safety of adenoidectomy regarding velopharyngeal function in the long term.
