Insights

Sublingual dermoids, rare floor of mouth lesions, can cause significant issues in infants. Early surgical intervention is crucial for large congenital dermoid cysts presenting with respiratory distress.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Pediatric Surgery
  • Dermatology

Background:

  • Sublingual dermoids are rare congenital cysts found in the floor of the mouth.
  • While typically presenting in early adulthood, they can occur in infancy, posing unique challenges.

Observation:

  • An 8-month-old infant presented with mouth-closing difficulties, stridor, and snoring.
  • Magnetic Resonance Imaging (MRI) indicated a sublingual dermoid, later confirmed by histopathology post-surgery.

Findings:

  • Large sublingual dermoid cysts in neonates can lead to respiratory distress, necessitating prompt surgical management.
  • Intraoral surgical enucleation is the preferred treatment, with external approaches reserved for extensive cysts below the mylohyoid muscle.

Implications:

  • Sublingual dermoids in infants require careful anesthetic planning due to potential airway compromise.
  • Timely diagnosis and surgical intervention are vital for managing respiratory embarrassment caused by congenital floor of mouth masses.

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

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...

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...
