Thanks for writing to us.
Kindly consult a General Surgeon
to get the part repaired by secondary suturing under local Anaesthesia. Only the cut ends will be freshened up with edges being trimed and sutured back into place after thoroughly cleaning the area , a process called wound toilet or debridement.
Better later than never.
Get a jab of tetanous toxoid before the Surgery.
with left out old ointments
/Medicines is highly dangerous.
Get well soon,
Dr Lt Cdr ASN Bhushan.
