Objective:

The objective of this study was to analyze the clinical characteristics in patients with congenital middle ear malformation. And summarize the key diagnostic points, differential diagnosis and observe the effects of surgical treatment.

Materials and methods:

The authors conducted a retrospective 33 cases (33ears) from Jan. 2015 to Feb. 2017 in patients from otolaryngology in our hospital. There were 26 cases of unilateral and 7 cases of bilateral. The history, clinical symptoms, audiological evaluation, high resolution temporal bone CT, the results of surgical exploration and hearing reconstruction were analyzed.

Results:

Base on the Teunissen classification in 1993, patients were classified into 4 categories: type I (3 cases isolated stapes ankylosis); type II (5 cases stapes ankyosis with other ossicular malformation); type III (8 cases ossicular malformation with mobile stapes); type IV (17 cases aplasia or dysplasia of the oval or round window). 17 cases Reconstruction Surgery included Vestibular window fenestration; 8 cases Stapedotomy; 4 cases TympanoplastyII; Tympanoplasty III. 20 cases Stapes malformation is also common in our data. After operation, the Air-Bone-Gap (ABG) less than 20dBHL (26 cases), the ABG greater than 20dBHL (2 cases), loss to follow up (4 cases), and there was 1 case suffered from the head trauma after surgery.

Conclusion:

Congenital middle ear malformation with intact external can be complex and diverse. Imaging examination is very important for the diagnosis of congenital middle ear malformation. Surgery is the main treatment. Functional ossiculoplasty can achieve good hearing outcomes.
