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 a hearing reconstruction scheme by adopting a simulation mold. The ear of a patient is scanned through CT, tissue structure information of the earof the patient is obtained, CT data is formed, and the related tissue structure information comprises auricles, ear canal front wall cartilages and bone plates, mastoid process rear walls and canopy bone plates, tympanic chamber inner side walls, ear canal rear walls, tympanic membranes, ossicular chains, tympanic antrum, mastoid process air chambers and upper tympanic cavity. The method comprisesthe following steps of: acquiring CT data of an affected part of a patient; since the CT data can display related lesion information in a real object manner, combining 3D printing techniques and printing a 3D simulation mold, performing surgery rehearsal on the 3D simulation model, performing hearing test on the 3D simulation model after surgery, obtaining an optimal surgery case according to thehearing test condition, and guiding a doctor to perform subsequent actual surgery according to the optimal case, so that the surgery has a very good quantitative standard, and the best surgery schemeis given to a 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...
