This paper reports a rare case of cerebrospinal fluid leak due to a Hyrtl's fissure and discusses the non-operative management of the case.
Background and case report:
Cerebrospinal fluid otorrhoea is a rare phenomenon arising from an abnormal communicating tract between the subarachnoid space and middle ear. Affected patients are at a higher risk of developing meningitis and other neuro-otological complications. There are four common congenital causes of cerebrospinal fluid otorrhoea in the region of a normal labyrinth. This paper describes a case of cerebrospinal fluid in the middle ear resulting from a Hyrtl's fissure, which resolved spontaneously.
A literature search indicated this to be the first case with such a resolution without the need for any intervention.
In laboratory tests, Ravinia lherminieri (Robineau-Desvoidy) larvae significantly reduced the numbers of face fly, Musca autumnalis De Geer, eggs or larvae (98% mortality), in 100 ml of bovine feces at R. lherminieri to face fly ratios down to 10:200. Face fly immature mortality due to R. lherminieri decreased from 98% to 0% as the volume of feces per larva increased from 10 ml to 80 ml. Although R. lherminieri larvae survived on feces alone, their survival increased 26% (63% vs. 89%) when face fly immatures were added to the feces.
