    Insights

    Congenital choanal atresia affects 1 in 3100 births, with many cases missed initially. Younger mothers with fewer children had a higher incidence of this nasal blockage in infants.

    Area of Science:

    • Otolaryngology
    • Pediatric Surgery
    • Medical Genetics

    Background:

    • Congenital choanal atresia is a rare birth defect affecting nasal breathing.
    • Accurate incidence data and associated risk factors require further investigation.

    Purpose of the Study:

    • To describe the incidence and clinical characteristics of congenital choanal atresia.
    • To identify potential maternal and infant risk factors associated with the anomaly.

    Main Methods:

    • Retrospective review of 11 congenital choanal atresia cases over two years.
    • Analysis of incidence, missed diagnoses, maternal factors, and associated anomalies.

    Main Results:

    • Incidence estimated at 1 in 3100 births; 27% missed at birth.
    • Higher incidence linked to younger mothers with fewer than four children (P ≤ 0.05).
    • Maternal polyhydramnios significantly associated (P ≤ 0.0001); bilateral atresia common; five infants had anomalies.

    Conclusions:

    • Congenital choanal atresia diagnosis can be delayed; early recognition is crucial.
    • Maternal age and parity, along with polyhydramnios, are potential indicators.
    • Associated anomalies are frequent, necessitating comprehensive infant evaluation.

    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 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.

    Esophageal Achalasia01:27

    Esophageal Achalasia

    Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
    Pyloric Obstruction01:11

    Pyloric Obstruction

    Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
