Objective:
We present an unusual case of a 12-year-old child with state-dependent laryngomalacia presenting after anaesthesia with a laryngeal mask airway.
Method:
Current literature on state-dependent laryngomalacia and injury following laryngeal mask use is reviewed.
Results:
A child who had previously suffered with laryngomalacia as an infant presented with disturbed breathing at night and during exercise. After anaesthesia using a laryngeal mask airway, these symptoms became more pronounced. Microlaryngoscopy revealed laryngomalacic type movement of the larynx.
Conclusion:
Our case seems to support a more complex, multifactorial aetiology for laryngomalacia, including both the neurological control of the larynx as well as its structure.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
