Interval right partial mastoidectomy and temporal craniectomy noted with mild pneumocephalus, and small right cerebellopontine/para-pontine fluid collection with moderate mass effect displacing the right middle cerebellar peduncle and partially effacing the 4th ventricle. Subtle midline linear density superior to this may represent tiny extraaxial blood layering over the posterior falx cerebri.
No any other evidence of a surgical site haemorrhage.
Within the constraints of this study, there is evidence of hypo/mesotympanic posterior wall destruction and partial semicircular and cochlear resection.
Conclusion: No significant early post-op complication identified
