Why does mastoiditis of middle ear still flow pus after operation

summary

My son has just suffered from mastoiditis, mainly in the decline of resistance, otitis media complicated with mastoiditis, in the process of treatment, to avoid pus is very important. Let's take a look at the reasons why there is still pus after the operation of otitis media and mastoiditis.

Why does mastoiditis of middle ear still flow pus after operation

First of all: the operation is not standardized, and the focus is not completely removed: more than 80% of the cases in this group are not standardized, so that the lesion tissue remains in the corner, crypt, mastoid air chamber and other places. In addition, the posterior wall of the external auditory canal is too high, the upper and lower tympanic chambers are not completely opened, the postoperative drainage is not smooth, the secretion remains, stimulating the mucosal congestion and edema in the operation cavity, and can not be epithelialized, so long-term pus. This is related to the poor basic theoretical knowledge, unskilled basic skills and lack of clinical experience.

Secondly, the purpose is not clear, and the intraoperative treatment is not proper: some doctors completely remove the pathological tissue in the middle ear mastoid surgery, but also destroy all the middle ear sound transmission structure, so that patients lose the opportunity of hearing reconstruction. In order to meet the psychological and requirements of patients, some surgeons not only want to remove the focus tissue, but also want to retain part of the hearing. As a result, the removal is not complete and the retention is not retained, resulting in incomplete removal of the lesion tissue and unconditional hearing reconstruction.

Finally: lack of equipment, operation is not in place: in addition to general instruments, the middle ear mastoid surgery must have ear drill and operating microscope, in order to open the upper and lower tympanic chamber, tympanic sinus orifice, mastoid air chamber and external auditory canal, completely remove the hidden and tiny pathological tissue, make the operation cavity easy to epithelization, obtain dry ear. At present, hospitals without certain medical equipment should be cautious in middle ear and mastoid surgery. When patients choose hospitals, they should comprehensively investigate the strength of hospitals.

matters needing attention

Never treat radical mastoidectomy as a simple small operation. You should go to a qualified hospital and find an experienced doctor for the operation. After the operation, closely observe the abnormality of the body and communicate with the doctor in time.
