Meningolysis

**Meningolysis**c (meningolyхis) is a surgical procedure that involves removing pus from the meninges (usually along with fibrinous adhesions caused by rheumatic diseases or syphilis).

Defect of the meninges with pleurisy (pleuriolysis) or extensive lesions of the lung tissue (atelectasis, cystic pneumonia, cavitary tuberculosis, etc.) is observed very rarely

**Meningolysis** most often occurs with meningitis, encephalitis, various hydrocephalus (for example spinal) as a result of the formation of free spaces. Abundant destruction of pus and its removal from the connective membrane with the help of thin instruments leads to the disappearance of adhesions. In case of brain abscesses, free removal of pus should occur by craniotomy. There can be no question of performing trepanation and freeing the brain from adhesions only by aspiration of pus in case of auricular empyema (acute purulent otitis media) or sinusitis. However, such cases are known: the French ENT Lauenstein wrote in 1825 about the possibility of a meningoloic method of treating epitympanitis; F. Bowman and R. Lehner in the 40-50s of the 20th century also made a number of attempts in this direction (pleuropulmonectomy, pneumolysis through a perforation ); however, later the American otolaryngologist W.S.

Meningiolysis is a procedure performed to remove the inner lining of the dura mater (arachnoid membrane) of the brain. It can be performed as a stand-alone procedure or in combination with other treatments.

Causes of meningolysis may include tumors and infections that put pressure on this lining. Besides,
