Insights

Infantile myofibroma, a rare fibrous tumor, can cause airway obstruction in infants. Complete surgical resection via a transoral approach successfully treated an eight-month-old with this condition, showing no recurrence after five years.

Area of Science:

  • Pediatric Oncology
  • Surgical Pathology
  • Otolaryngology

Background:

  • Infantile myofibroma is a rare benign fibrous tumor typically presenting at birth.
  • Airway obstruction is an uncommon but serious complication of infantile myofibroma.
  • Neonatal and infant cases of infantile myofibroma causing airway compromise are exceptionally rare.

Observation:

  • An eight-month-old infant presented with progressive respiratory distress.
  • A computed tomography (CT) scan revealed a large (7x5x5cm) mass in the left parapharyngeal space, obstructing the oropharynx.
  • The mass exhibited well-defined margins.

Findings:

  • Complete surgical resection of the parapharyngeal infantile myofibroma was achieved using a transoral approach.
  • The surgical procedure was completed without intraoperative complications.
  • Post-operative follow-up for five years showed no evidence of tumor recurrence or long-term sequelae.

Implications:

  • The transoral approach is a viable and effective surgical strategy for managing parapharyngeal infantile myofibromas in infants.
  • Early diagnosis and complete resection can lead to excellent long-term outcomes for infantile myofibroma.
  • This case expands the understanding of infantile myofibroma as a cause of pediatric airway obstruction and highlights successful surgical management.

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...

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...

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 the...
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)...

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by anesthetizing...
