Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

2.9K
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.

Chronic Pharyngitis01:23

Chronic Pharyngitis

10.8K
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,...

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

10.3K
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 Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

777
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...

Pharynx01:20

Pharynx

5.9K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

4.7K
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....

Summary

Post-adenoidectomy hypernasality is rare in children. This study found no link between velopharyngeal valve (VPV) closure patterns and hypernasality, suggesting preoperative VPV assessment minimizes risks.

Area of Science:

  • Otolaryngology
  • Speech Pathology
  • Pediatric Surgery

Background:

  • Hypernasality is a speech disorder linked to various conditions.
  • The prevalence of hypernasality after adenoidectomy is not well-established.
  • Understanding velopharyngeal valve (VPV) function is crucial for managing speech disorders.

Purpose of the Study:

  • To investigate the relationship between VPV closure patterns and hypernasality post-adenoidectomy.
  • To determine the incidence of hypernasality following adenoidectomy in children.
  • To assess the impact of adenoidectomy on VPV function and speech resonance.

Main Methods:

  • A prospective observational study of 100 children (aged 6-12) undergoing adenoidectomy.
  • Nasoendoscopic evaluation of VPV function preoperatively.
  • Postoperative assessment of hypernasality at 2 weeks and monthly for 3 months.

Main Results:

  • Preoperatively, all patients had normal VPV closure; 15% had mild hyponasality.
  • Postoperatively, only 5% experienced mild transient hypernasality at 2 weeks.
  • All patients achieved normal resonance by the 1-month follow-up.

Conclusions:

  • No significant association was found between VPV closure patterns and postoperative hypernasality.
  • Preoperative assessment of VPV function is key to minimizing hypernasality risk.
  • Adenoidectomy generally does not lead to persistent hypernasality when VPV function is adequate.
