Introduction

Sama-Bajau people with a perforated eardrum can generally still hear sounds. Hearing typically occurs through air conduction and bone conduction mechanisms. Although a perforated eardrums in Sama-Bajau individuals may lead to reduced eardrum function and some degree of hearing loss, sound can still reach the eardrum via air transmission, allowing them to perceive sound. If the eardrum is perforated, it is recommended to seek medical attention promptly and consider medication or surgical treatment for improvement.

The Bajau people can generally still hear sounds even if their eardrums are ruptured.

Normally, hearing occurs through air conduction and bone conduction mechanisms. In air conduction, sound waves are collected by the pinna, travel through the external auditory canal, and reach the eardrum, causing vibrations that activate the ossicular chain and transmit sound to the inner ear. In bone conduction, sound waves travel directly through the skull bones to the inner ear. Therefore, although a ruptured eardrum in the Bajau may impair eardrum function and lead to some degree of hearing loss, sound can still be perceived via air conduction reaching the eardrum.

In daily life, if a ruptured eardrum occurs, it is recommended to promptly undergo appropriate medical evaluations under a doctor's guidance. Depending on the severity of the eardrum perforation, treatment may involve medication or surgical intervention to promote healing.

Can flying in an airplane cause a ruptured eardrum?

Under normal circumstances, the eardrum may rupture during air travel due to changes in cabin air pressure affecting the eardrum. During takeoff and landing, the air pressure inside the aircraft cabin changes. If the pressure of the air on the outer side of the eardrum is not adjusted promptly, a pressure difference can develop across the eardrum, leading to discomfort such as tinnitus, ear pain, and hearing loss. In severe cases, this pressure imbalance may result in eardrum rupture.

Does bleeding after cleaning the ears mean the eardrum is ruptured?

The skin of the external auditory canal is relatively thin. Excessive force during ear cleaning or external impact can easily perforate the eardrum, causing bleeding. Because the external auditory canal is deep and narrow, with blood vessels and nerves attached to its walls, improper manipulation during ear cleaning may injure the skin of the canal wall, leading to bleeding as well.

Can frequent sneezing harm your body?

Frequent sneezing may lead to symptoms such as ruptured eardrums, lumbar muscle strain, lumbar disc herniation, and cerebral hemorrhage; therefore, prompt medical attention is recommended. Sneezing causes a sudden increase in pressure within the middle ear, and repeated sneezing may result in eardrum rupture. Sneezing can also cause a rise in blood pressure, which, in individuals with pre-existing brain or cerebrovascular conditions, may lead to rupture of cerebral blood vessels.

Can a perforated eardrum cause bleeding?

A ruptured eardrum typically results in bleeding. For example, cleaning the ear too deeply without proper depth awareness may puncture the eardrum, or a ruptured eardrum may occur due to strong external force, usually causing slight bleeding. Additionally, in cases of otitis media, pus accumulates in the middle ear and increased pressure may cause the eardrum to rupture, leading to bleeding as well. However, since this is often accompanied by a large amount of pus draining into the external auditory canal, the bleeding is generally not obvious.
