POST-TRAUMATIC PERFORATION OF THE EARDRUM

Abstract

SUMMARY. For many years, post-traumatic perforations of the tympanic membrane are among the most common injuries in otolaryngology. This topic is particularly relevant in childhood. The procedure of closing the perforation in order to restore the integrity of the eardrum requires improvement.

The aim – to improve the treatment efficiency of patients with traumatic tympanic membrane perforations by using a lyophilized xenodermograft to close the defect.

Material and Methods. 26 patients with traumatic tympanic membrane perforations were studied. 14 men and 11 women, aged 16 to 47 took part in the study. The duration of the disease ranged from 1 to 5 days.

 Results. The proposed method of traumatic tympanic membrane perforation with a size of not more than 10 mm closure, using 0.3–0.5 mm thick lyophilized xenodermograft allowed to create physiological conditions in the middle ear, which is important for successful regeneration of the tympanic membrane. The possibility of diffuse otitis externa deve­lopment is also excluded, as the procedure does not require the creation of additional pressure in the ear canal. This helped to improve the general condition and hearing of patients.

Conclusions. 1. The technique of myringoplasty using lyophilized xenodermograft eliminates the risk of diffuse otitis externa, as this technique does not require additional pressure on the skin of the external auditory canal.

2. Closing the defect of the tympanic membrane up to 5 days after injury by using a lyophilized xenodermograft ensures the successful restoration of tympanic membrane integrity.
