Percutaneous dilatational tracheostomy: review of technique and evidence for its use

Tracheostomy is a technique for airway management commonly used by surgeons who care for critically ill patients. Patients with traumatic facial injuries, severe odontogenic infections, and head and neck malignancies are often recipients of tracheostomies. As such, the oral and maxillofacial surgeon who frequently treats such patients should be well-trained in tracheostomy placement. For decades, the standard technique for tracheostomy was the open surgical technique. However, during the past 20 years, the use of percutaneous dilatational tracheostomy has increased. The purpose of the present report is to review the percutaneous dilatational tracheostomy technique, describe the use of intensive care units as proxies for the operating room, and review the available evidence comparing percutaneous dilatational tracheostomy to open tracheostomy.
