Summary
Bilateral temporomandibular joint (TMJ) dislocation is a rare complication following endotracheal intubation. Prompt recognition and repositioning are crucial to prevent long-term TMJ dysfunction and pain.
Area of Science:
- Oral and Maxillofacial Surgery
- Anesthesiology
- Emergency Medicine
Background:
- Temporomandibular joint (TMJ) dislocations occur in up to 7% of the population.
- Anterior dislocations, involving forward movement of the mandibular condyle, are most common.
- Bilateral TMJ dislocation post-intubation is an uncommon complication.
Purpose of the Study:
- To report a rare case of bilateral temporomandibular joint dislocation following endotracheal intubation.
- To highlight the importance of early recognition and management of this complication.
Main Methods:
- A 43-year-old female patient presented with respiratory distress and underwent endotracheal intubation.
- Post-extubation, the patient developed inability to close her mouth, speak, or swallow.
- Computed tomography confirmed bilateral TMJ dislocation, which was successfully repositioned by an ENT specialist under sedation.
Main Results:
- Computed tomography revealed bilateral temporomandibular joint dislocation.
- Successful manual repositioning of the mandible restored normal jaw anatomy and function.
- The patient's symptoms resolved after the procedure.
Conclusions:
- Endotracheal intubation is a predisposing factor for TMJ dislocation.
- Risk factors include female sex, interincisal distance, and age.
- Delayed treatment can lead to difficult repositioning, muscle spasms, and long-lasting dysfunction or pain.

Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
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...

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

01:29Mechanical Ventilation I: Indication and Settings
112
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

01:26Pneumothorax-I
154
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
