Insights

This study developed a growth curve for the nasal pyriform aperture in children with congenital nasal pyriform aperture stenosis (CNPAS). This curve aids in managing CNPAS by identifying when more aggressive treatment is needed.

Area of Science:

  • Pediatric Otolaryngology
  • Craniofacial Development
  • Medical Imaging

Background:

  • Congenital nasal pyriform aperture stenosis (CNPAS) can present with varying severity.
  • Symptoms in CNPAS patients may decrease with age, complicating treatment decisions.
  • Objective assessment of pyriform aperture growth is needed for effective management.

Purpose of the Study:

  • To establish a normative growth curve for the nasal pyriform aperture in children.
  • To provide a tool for evaluating the progression of CNPAS.
  • To aid in developing comprehensive treatment plans for CNPAS patients unresponsive to conservative care.

Main Methods:

  • Retrospective review of 54 patients with CNPAS from November 1997 to December 2014.
  • Measurement of inter-maxillary process distance (IPD) using 3D computed tomography (CT) scans.
  • Construction of a pyriform aperture growth curve based on age and IPD data.

Main Results:

  • The mean IPD increased with age, ranging from 3.57 mm in neonates to 9.20 mm in children over 36 months.
  • A cubic growth curve model was found to be the most appropriate fit for the data.
  • Pyriform aperture growth showed a tendency to slow between 3.5 and 6 years of age.

Conclusions:

  • The developed growth curve serves as a valuable tool for CNPAS treatment planning and outcome prediction.
  • Deviations from the normative growth curve warrant consideration for more aggressive interventions.
  • This tool can guide decisions regarding observation, conservative treatment, or surgical options for CNPAS.

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

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 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.

Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

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...

Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Trachea01:22

Trachea

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...
