Grading of microtia

Microauricular malformation is a congenital malformation of the ear, which is characterized by abnormal shape, size or position of the auricle. According to the severity of the malformation, microtia can be divided into different levels. Understanding the classification of microtia is of great significance for the diagnosis, treatment and prognosis evaluation of patients.

Grading standard of microtia

At present, the commonly used classification standard of microtia is based on the shape and structure of the auricle. In general, microtia can be divided into the following levels:

1. * * Grade I * *: The shape of the auricle is basically normal, but there may be slight malformations, such as slight differences in the size of the auricle or slight deviation in the position of the earlobe.

2. * * Grade II * *: The shape of the auricle is obviously deformed, such as the size of the auricle is significantly reduced, the position of the earlobe is significantly shifted, or the structure of the auricle is incomplete.

3. * * Grade III * *: The auricle is severely deformed, such as most or all of the auricle is missing, and only a small amount of auricle tissue remains.

4. * * Grade IV * *: The auricle is completely missing, and only a small amount of tissues such as earlobe or tragus remain.

Treatment of microtia

The treatment of microtia mainly includes surgical treatment and non-surgical treatment. Surgical treatment is the main method to treat microtia at present, including auricle reconstruction, external auditory canal plasty and hearing reconstruction. Non operative treatment mainly includes wearing hearing aids and auricle orthotics.

Prognostic evaluation of microtia

The prognosis of microtia mainly includes the shape and functional recovery of auricle. Generally speaking, the shape and function of the auricle recover well after surgical treatment, but the specific prognosis evaluation needs to be comprehensively evaluated according to the individual condition of the patient.

In conclusion, microtia is a common congenital malformation of the ear. Understanding the classification of microtia is of great significance for the diagnosis, treatment and prognosis of patients. If you or your family suffer from microtia, it is recommended to consult a professional doctor in time to obtain better treatment effect.
