What is the most dangerous complication of arthrocentesis?

• A. Joint infection
• B. Fluid accumulation in the lateral pharyngeal space
• C. Cognitive disorientation
• D. Facial nerve injury

Answer: (B)

Fluid accumulation in the lateral pharyngeal space is considered the most dangerous complication of arthrocentesis. This procedure, typically performed to treat temporomandibular joint (TMJ) disorders, involves the placement of a needle into the joint space to aspirate fluid or inject medication. If the procedure is not executed with precision, there is a potential risk for fluid to enter the lateral pharyngeal space, which can lead to serious complications such as compression of the airway or vascular structures in that area. The lateral pharyngeal space is anatomically complex, containing vital structures such as the carotid artery and jugular vein, along with the vagus and glossopharyngeal nerves. Accumulation of fluid in this space can result in significant swelling and lead to respiratory distress or airway compromise, making it a critical concern for clinicians performing this procedure. In contrast, while joint infection, cognitive disorientation, and facial nerve injury are notable risks, they do not typically carry the immediate high-stakes implications associated with the potential for airway obstruction due to fluid accumulation in the lateral pharyngeal space. Joint infections can usually be managed with antibiotics, cognitive disorientation is more related to sedation than the arthrocentesis
