Quality of life after revision mastoidectomy with mastoid obliteration

Aims

To evaluate the postoperative quality of life (QoL) after revision canal wall down mastoidectomy with mastoid obliteration (rCWD).

Material and methods

A retrospective analysis was conducted on patients treated by rCWD for cholesteatoma between 2016 and 2019. A control group including all patients treated by primary canal wall down with mastoid obliteration (pCWD) for cholesteatoma between 2009 and 2014 was used for the comparison of the postoperative QoL, assessed by the COMQ-12.

Results

The rCWD and pCWD groups respectively counted 38 and 78 patients with an average follow-up of 30 and 62 months respectively. No significant difference was found in terms of QoL between the two groups. An intra-group analysis among rCWD patients, showed that patients treated by canal wall down (CWD) at the primary surgery had a significantly worse post-revision QoL compared to those initially treated by canal wall up (CWU), specifically in the hearing and balance domains of the questionnaire.

Conclusions

Revision mastoid obliteration leads to similar QoL results to those obtained after primary CWD with obliteration. Patients who had undergone a CWD as primary surgery complain worse hearing and balance problems compared to those primarily submitted to CWU, even after revision surgery.
