Abstract:
A 2 year-old boy presented with acute upper airway obstruction following a 15-month history of noisy breathing and hoarseness. An urgent laryngotracheal bronchoscopy was performed following inhalational induction of anesthesia. Using a fiberoptic bronchoscope, visualization of the larynx through a laryngeal mask airway revealed a flat plastic Christmas tree embedded within granulomatous cords causing almost complete obstruction and requiring tracheostomy prior to extraction. Twelve days later, the tracheostomy was successfully decannulated with the child's voice beginning to normalize. The family remembered the decoration from Christmas celebrations 2 years prior and recalled a coughing episode that predated the onset of hoarseness.

Larynx
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...
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
Trachea
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...
Pharynx
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
