The near complete tracheal ring deformity
1Department of Otolaryngology-Head and Neck Surgery, Mayo, Minneapolis, MN 55455, USA.
Abstract:
Congenital complete and near-complete tracheal rings are extremely rare tracheal deformities. There are fewer than 100 cases of congenital complete tracheal rings, and only four cases of near-complete described in the literature. Long-segment occurrences of these anomalies are usually incompatible with life. We describe the presentation of the long-segment near complete tracheal ring deformity and long-segment anterior fusion of cartilage rings (cartilage sleeve deformity) in a living infant. The literature is reviewed, and the embryology, presentation, and management of these extremely rare anomalies are discussed.

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...
Anatomy of Respiratory System II: Lower Respiratory Tract
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...
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
Oxygen Delivering System III: Tracheostomy and T-piece
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Tracheostomy Decannulation
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...
