Intubation granuloma is a benign growth of granulation tissue in the larynx or trachea, which arises from tissue trauma due to endotracheal intubation. [1] This medical condition is described as a common late complication of tracheal intubation, specifically caused by irritation to the mucosal tissue of the airway during insertion or removal of the patient's intubation tube.
Intubation is normally facilitated by using a conventional laryngoscope, flexible fiberoptic bronchoscope, or video laryngoscope to identify the vocal cords and pass the tube between them into the trachea instead of into the esophagus. Other devices and techniques may be used alternatively.
In patients with known difficult airways, fiberoptic intubation can be considered. This technique involves the use of a flexible fiberoptic bronchoscope for visualization of the vocal cords. The bronchoscope can be passed directly into the trachea and the endotracheal tube can be threaded over the bronchoscope into position.
Aspiration pneumonia: Particles entering the lungs can cause infections. [8] Structural changes: Repeating obstruction or trauma may scar or narrow the upper airway. This is called subglottic or tracheal stenosis. [9] [page needed] Voice changes: Chronic damage to the vocal cords may cause permanent voice changes or loss. [1] [page needed]
Contact granuloma is a condition that develops due to persistent tissue irritation in the posterior larynx. [1] [2] Benign granulomas, not to be confused with other types of granulomas, occur on the vocal process of the vocal folds, where the vocal ligament attaches.
Cricoid pressure, also known as the Sellick manoeuvre or Sellick maneuver, is a technique used in endotracheal intubation to try to reduce the risk of regurgitation.The technique involves the application of pressure to the cricoid cartilage at the neck, thus occluding the esophagus which passes directly behind it.
High cuff pressure or long-term intubation can cause damage to the tracheal mucosa, causing inflammation, ulceration, and breakdown of cartilage. [3] When the injury heals, scarring occurs, narrowing the airway. [4] Treatment-related risk factors include repeated intubation, the presence of a nasogastric tube, and size of an endotracheal tube.
The valleculae can collect saliva to prevent initiation of the swallowing reflex. The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis .
