Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0023] Such as Figure 1-Figure 3 As shown, a test method for optimizing the hearing reconstruction scheme using a simulation mold includes the following steps:

[0024] S100. Scan the patient's ear through CT to obtain the tissue information of the patient's ear and form CT data. The tissue information involved includes the auricle 1, the anterior wall cartilage and bone plate 2 of the ear canal, the posterior wall of the mastoid and the Cover plate 3, inner wall of tympanic cavity 4, posterior wall of ear canal 5, tympanic membrane 6, ossicular chain 7, tympanic antrum 8, mastoid air cell and upper tympanic cavity 9;

[0025] S200. Transmitting the CT data to a 3D printing device, printing each tissue in S100 separately through the 3D printing device, and assembling the printed tissue parts to obtain a corresponding 3D simulation mold;

[0026] S300. Perf...

Abstract

The invention discloses a test method for optimizing the hearing reconstruction scheme by using a simulation mold. The patient's ear is scanned by CT to obtain tissue structure information of the patient's ear and form CT data. The tissue structure information involved includes the auricle , cartilage and bone plate of the anterior wall of the ear canal, posterior wall of the mastoid process and bony plate of the canopy, medial wall of the tympanic cavity, posterior wall of the ear canal, tympanic membrane, ossicular chain, sinus tympani, mastoid air cells and upper tympanic cavity. The present invention obtains the CT data of the sick part of the patient, because the CT data can display the relevant lesion information in kind, and then combines the 3D printing technology to print out the 3D simulation model, and performs the operation "rehearsal" on the 3D simulation model, and then " The 3D simulation model after "surgery" is used for hearing test, and the optimal "surgery" case is obtained according to the audiometry test, and the doctor's follow-up actual operation is guided according to the optimal case, so that the operation has a good quantitative standard, to give The best surgical option for the patient.

Description

technical field [0001] The invention relates to the technical field of medical evaluation, in particular to a test method for optimizing a hearing reconstruction scheme by using a simulation mold. Background technique [0002] Benign middle ear mastoid lesions are represented by chronic suppurative otitis media (CSOM) and middle ear cholesteatoma (cholesteotoma). life. A CSOM study in China showed that 54% of cholesteatoma patients also suffered from ossicular chain damage (OCD), which caused conductive hearing loss and significantly affected the quality of life of patients. The most effective treatment for such diseases is surgery, but the surgery is complicated and can easily lead to complications such as facial nerve loss and cerebrospinal fluid otorrhea after surgery. Surgery is to remove the middle ear mastoid lesion and reconstruct the sound transmission structure of the middle and outer ear. The representative surgical method is open or complete radical mastoidectom...
