Cutting of the Cartilage of the Auditory Canal [Incisura Cartilaginis Meatus Acustici, Pna; Incisura Cartilaginis Meatus Acustici Externi (Santorini), Bna; Syn. Santorini Tenderloin]

The cartilage cut of the auditory canal is one of the important anatomical elements of the external auditory canal. It is a paired vertical depression located in its cartilaginous part. Cartilage cutting performs several functions.

Firstly, it protects the ear canal from mechanical damage and infections. Secondly, the cartilage notch facilitates the passage of air through the auditory canal into the tympanic cavity. Thirdly, it is the site of attachment of the muscles that control the movement of the auditory canal.

The cut cartilage is important for the normal functioning of the hearing aid, so damage to it can lead to serious hearing problems. In addition, improper location or size of the cartilage notch can cause various diseases associated with obstruction of the ear canal or hearing disorders.

To diagnose and treat diseases associated with cartilage cutting, it is necessary to conduct a thorough examination of the patient. In some cases, surgery may be required to restore normal ear canal function and hearing.

Thus, cartilage cutting is an important element of the hearing aid and requires attention from an otolaryngologist. Timely detection and treatment of diseases associated with this anatomical structure can prevent serious hearing problems and maintain the health of the hearing system.

Cartilage Cutting of the Auditory Canal: Anatomy and Role

The cartilage notch of the auditory canal, also known as the incisura cartilaginis meatus acustici or Santorini notch, is a paired vertical depression in the cartilaginous portion of the external auditory canal, filled with loose connective tissue. In this article we will look at the anatomical features of this structure and its role in the body.

Anatomical features

The cartilage notch of the auditory canal is located in the cartilaginous part of the external auditory canal, which is part of the outer ear. It is a paired vertical depression in the cartilage, forming a sinus filled with loose connective tissue.

The role of the cartilage cutting of the auditory canal

The exact role of the ear canal cartilage notch in the body is not yet fully understood. However, some studies indicate that this structure may play a role in acoustic and mechanical protection of the ear canal.

One possible function of the ear canal cartilage notch is related to acoustic protection. The loose connective tissue filling the notch sinus can serve as a shock-absorbing material, reducing the intensity of sound waves passing through the external auditory canal. This assumption is based on the observation that loose connective tissue has shock-absorbing properties.

In addition, the cartilage notch of the ear canal may play a role in mechanical protection. Due to its position and structure, it can serve as additional protection for the ear canal from external traumatic influences such as shock or pressure.

Further research is needed to fully understand the role of the cartilage notch of the ear canal and its relationship to other ear structures. The anatomical variations of this structure also require further study.

Conclusion

The notch of the cartilage of the auditory canal is a paired vertical depression in the cartilage of the external auditory canal, filled with loose connective tissue. Its exact role in the body is not yet fully understood, but it is believed that it may serve as acoustic and mechanical protection for the ear canal. Further research is needed to better understand this structure and its functions.
