Introduction:
Post-auricular incisions are performed for a range of otological procedures. Anecdotally, many patients suffer some numbness of the pinna or post-auricular skin post-operatively, but for most this appears to reduce with time. This study aimed to investigate this phenomenon.
Methods:
A single centre, questionnaire-based study was undertaken, assessing the presence of numbness beyond eight months post-surgery, its location, how it changed, and its impact on the patient. Patients whose numbness had resolved provided details of any temporary deficit. Data were acquired for 35 primary and 16 revision procedures.
Results And Conclusion:
Sixty-nine per cent of patients undergoing primary surgery experienced post-operative numbness. Twenty-six per cent had continued numbness after at least eight months' recovery, but only 3 per cent were constantly aware of the deficit. Of those with an ongoing deficit, 78 per cent felt there had been a reduction in the severity, and 67 per cent in the area size, over time. Recovery appeared to be slightly worse in revision cases.
