For example, with scuba diving, the pressure in the middle ear is unequal to the pressure in the external auditory canal, creating an air squeeze. For instance, perforation secondary to barotrauma is related to large or rapid changes in pressure gradients between the middle and external ear. The pathophysiology behind TM rupture depends on the etiology of the rupture itself. It is important to know when intervention and early referral is required, based on size, location, and symptoms associated with the perforation. Perforations tend to heal spontaneously without intervention. Overall, TM perforation has a favorable prognosis with a small risk of complications. Tinnitus and vertiginous symptoms may also be experienced. There is often sudden onset of pain, followed by relief, with associated otorrhea. Signs and symptoms of tympanic membrane perforation are the same despite the cause of the rupture. Men are more likely to experience TM perforation compared to women. As a patient's age increases, trauma becomes a more likely cause of TM rupture. Tympanic membrane rupture can occur at any age, although it is mainly seen in the younger population, associated with acute otitis media. When the tympanic membrane perforates, it may no longer create the vibrational patterns, leading to hearing loss in some instances. The TM function is to aid in hearing by creating vibrations whenever struck by sound waves and transmitting those vibrations to the inner ear. The TM is a layer of cartilaginous connective tissue, with skin on the outer surface and mucosa covering the inner surface that separates the external auditory canal from the middle ear and ossicles. ![]() ![]() Tympanic membrane perforation is when the tympanic membrane (TM) ruptures, creating a hole between the external and middle ear.
