Having a Hearing issue. Please advise.

Hi Specialists My sister met with an accident and got minor injury in head and bleeding from nose. So we consultated Nimhans Banglore and they took CT Scans & Xray and finally they told us she is perfect. We asked about bleeding but they told it is normal. After one day she couldn't able to hear in left ear and we consulted ENT specialist who near to me. He asked us to take Temporal CT Scan. In that scan result, we got below *Longitudinal fracture of left petrous temporal bone involving middle ear and 1st genu of facial nerve *dislocation of malleoincudal and incudostapedial joints *undisplaced fracture of squamous part of left temporal bone. *left haemomastoid and hemotympanum. Now my questions is, Is there any possible to cure these mentioned above with only on tablet's without having any surgeries. Please advise.
