Insights

Lateral positioning during drug-induced sleep endoscopy (DISE) significantly improves airway patency in children with obstructive sleep apnea (OSA), especially at the base of the tongue and larynx. This positional change offers a valuable diagnostic insight for pediatric OSA management.

Area of Science:

  • Pediatric Otolaryngology
  • Sleep Medicine
  • Diagnostic Imaging

Background:

  • Obstructive sleep apnea (OSA) is a common condition in children.
  • Drug-induced sleep endoscopy (DISE) is a key diagnostic tool for OSA.
  • Standard DISE positioning is typically supine, which may not reflect all airway dynamics.

Purpose of the Study:

  • To evaluate the impact of lateral positioning on drug-induced sleep endoscopy (DISE) findings in pediatric obstructive sleep apnea (OSA).
  • To compare upper airway obstruction patterns in supine versus left lateral positions during DISE.

Main Methods:

  • A cohort of 63 children with OSA undergoing DISE was studied.
  • Patients were assessed in both supine and left lateral (LL) positions.
  • Obstruction sites (palate, tonsils, base of tongue, larynx) were compared between positions.

Main Results:

  • Lateral positioning led to improved airway patency in 60.3% of patients, particularly at the base of the tongue and larynx.
  • Obstruction at the base of the tongue and larynx improved in 54% of patients when moving from supine to LL position.
  • While some sites improved, others could worsen, highlighting complex positional effects on airway collapse.

Conclusions:

  • Left lateral positioning during DISE can significantly enhance airway patency in children with OSA.
  • This positional maneuver provides critical information for surgical planning and understanding pediatric OSA.
  • DISE in lateral decubitus may reveal alternative airway routes not evident in supine positioning.

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Upper GI Series: Barium Swallow

The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...
