For most people, yawning is a natural and harmless act, especially on a leisurely summer day. However, one US-based influencer faced a terrifying ordeal when her jaw became stuck in an open position after a particularly wide yawn. Jenna Sinatra, a social media influencer from New Jersey, documented her painful journey to the hospital with an open jaw and revealed how doctors managed to resolve her unusual condition. The series of photos she shared on her Instagram page captured her experience, from the initial hospital visit to the X-ray examinations and the subsequent medical intervention that addressed her jaw issue. In the videos accompanying her posts, Jenna is seen communicating with the medical professionals despite her open jaw, which prompted surprise from the doctors, who expressed that they had never encountered such a condition in their medical practice. One doctor is heard explaining the treatment plan to Jenna, stating, “We are going to administer some medication, and then we will attempt to reposition your jaw.” In a follow-up post, Jenna shared an image of herself with a bandage around her head, indicating that her jaw had been successfully reset. She is seen having a light conversation with her mother in the photograph. Medical experts have stated that such cases of jaw locking are rare and typically occur due to jaw dislocation in individuals with Temporomandibular Joints (TMJ) problems. Dr. Anthony Youn explained the underlying cause of the condition, stating that “This is a rare condition, but when it does occur, it is often triggered by a wide yawn. One common cause is TMJ problems, and the treatment usually involves relaxation techniques followed by manual adjustment.” News of Jenna’s experience has sent ripples of shock and concern through the online community, with many expressing their disbelief and identifying with the fear associated with such a sudden and unexpected medical event. The incident serves as a reminder of the potential risks that can arise from seemingly innocuous everyday activities.
