Objective: This study aims to investigate the effects of stabilization of Total Ossicular Replacement Prosthesis (TORP) shaft with a cartilage shoe in patients who had canal wall down tympanomastoidectomy (CWDT). Alongside, it also aims to determine if presence of granular and edematous mucosa in middle ear alters the functional outcomes or not.


Methods: Sixty patients, who were administered CWDT and TORP was used were divided into two groups. Patients with cartilage shoe were called group 1 (n=30), patients without shoe called group 2 (n=30). The patients in both groups were classified to ‘A’ and ‘B’ subgroups according to the middle ear risk index (MERI). Air (AC) and bone conduction thresholds were evaluated preoperatively and postoperatively.


Results: There was not any statistically significant change between preoperative AC thresholds of groups and subgroups (p>0.05) There were statistically significant differences regarding AC thresholds and ABG values between group1 and 2 at 12th month (p<0.05). Postoperative AC thresholds and ABG values ​​of Group 1B patients with high MERI score were statistically significant at all frequencies when compared to Group 2B (p<0.05). When ABG values ​​were compared, it was seen that functional results were better in group 1B but there was statistically significant difference only at 2000 Hz (p<0.01).


Conclusion: Cartilage shoe method in stabilization of titanium TORP used for the reconstruction in CWDT has beneficial effect on auditory outcomes. Cartilage shoe application has positive effects on hearing outcomes especially if the middle ear mucosa is granular and edematous.
