Talk to Neuro Surgeon on Infection

my husband got tumour in his nose in 2006 which was removed by ENT .Then after 10 years recurrence of tumour in his frontal sinuses in which brain surgeon and ent did combine surgery n clean the tumour n also put titanium mesh.but last year he got 2 hole right after his hairline on forehead n slowly they got bigger n b can see his bone from then he was on antibiotics but nuthing works n there was a very bad smell coming from holes Dr suggest us to go for surgery n remove the infected bone but bcz of my husbands anxiety we took so much time for surgery n one day maggots came from holes he was scared n we rush to our doctor n they did his surgery they removed his infected bone n didn't take titanium mesh from there.now after a week his holes get expanded n its open. There plan is to put soft tissue under my forehead taken from my thigh instead of using artificial bone to reduce the risk of infection, They have also planned to replace my TITANIUM MESH with soft tissues again taken
