Insights

Children undergoing airway reconstruction may develop compensatory supraglottic phonation, leading to moderate to severe voice disorders. Understanding these vocal compensations is key for effective treatment.

Area of Science:

  • Laryngology
  • Pediatric Voice Disorders
  • Speech-Language Pathology

Background:

  • Airway reconstruction in children can lead to altered vocal fold function.
  • Supraglottic phonation is a compensatory mechanism observed in some pediatric patients post-surgery.

Purpose of the Study:

  • To investigate acoustic, aerodynamic, and perceptual voice measures in children with supraglottic phonation post-airway reconstruction.
  • To correlate these measures with surgical history and identify compensatory patterns.

Main Methods:

  • Study included 21 children (4-18 years) with supraglottic phonation.
  • Data collected included acoustic, aerodynamic, perceptual voice analyses, laryngeal imaging, and surgical history review.
  • Voice signals were classified by type, and compression patterns were identified.

Main Results:

  • Four supraglottic compression patterns and 3 voice sound sources were identified.
  • Most voice signals (20/21) were type II or III, moderately associated with compression patterns.
  • Higher mean Strain scores were found in participants using combined vibration sources compared to ventricular folds.

Conclusions:

  • Compensatory supraglottic patterns and alternate vibration sources contribute to moderate-to-severe dysphonia in these children.
  • Findings highlight the importance of understanding compensatory mechanisms for voice improvement interventions.
  • Traditional voice evaluation methods may not be fully applicable to this patient group.

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...
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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
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.

Tracheostomy Decannulation01:21

Tracheostomy Decannulation

Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
