Postoperative results of type III Endoscopic tympanoplastic surgery for patients with conductive hearing loss

Introduction:

We performed the type III Tympanoplastic surgery for 120 patients with conductive hearing loss between 2017 and 2018. Outcomes of the surgery are presented here.

Methods:

Hearing bone replacement surgery was done for 120 patients with middle ear conditions who meet with the following criteria: air conduction is more than 25 dB, air conduction vs. bone conduction is more than 15 dB by ENT examinations and hearing test.

Results of the study. Hearing bone replacement surgery was done for 120 patients with middle ear conditions who meet with the following criteria: air conduction is more than 25 dB, air conduction vs. bone conduction is more than 15 dB by ENT examinations and hearing test. Of those patients, 51 (42.5%) had cholesteatoma, 53 (44.2%) had (granuloma), and 16 (13,3%) had middle ear adhesive inflammation.

The tympanoplasty and replacement of hearing bone with titan prosthesis was done at the same surgery for patients with chronic middle ear infections and adhesive inflammation.

Of the total of 86 patients who had Type III Tympanoplasty PORP, 40 (45.5%) had 2.25 mm titan prosthesis replacements. Of those 72% had 10 – 25 dB hearing improvements. Of those 46 (54.5%) patients with 2.5 mm PORT, 89% had hearing improvements of 30 dB.

Type III Tympanoplasty TORP was done 34 (28.3%) patients with fully eroded hearing bones and of those patients 82% had 10 – 30 dB hearing improvement.

During the tympanoplasty surgery, we also used the cartilage and cartilage skin. Of those 86 patients who had PORP for hearing bones, 40 (45.5%) had titan prosthesis replacement of 2.25 mm. 72% of those patients had 10 – 25 dB hearing improvement. Of those 46 (54.5%) patients who had 2.5 mm PORP, 89% had 30 dB hearing improvement.
