Five patients with large arteriovenous malformations (AVM) of the head and neck, which were too large or inconveniently placed for operation alone, were treated by embolisation after direct puncture; two of them were subsequently operated upon. They all recovered without complications. Embolisation of the nidus and subsequent operation is a good alternative for the treatment of large AVM. Ligating the supplying arteries is not a treatment. If the arterial routes to the nidus have previously been closed by ligatures selective catheterisation is impossible, though direct puncture of the nidus is a possibility. The nidus of the AVM can then be obliterated by embolisation either as a treatment, or as a preoperative procedure.
A series of myringoplasties is presented and those cases that did not heal perfect are discussed.In order to evaluate whether some changes in the technique could further improve the results, another series incorporating these changes was operated after and the results are presented. Differences in healing and post-operative hearing between the two groups of patients are evaluated.
In closing an uncomplicated central drum defect the technique known as an ‘underlay’is widely used. This method has certain advantages and yields good results as far as both healing and hearing are concerned. In an attempt further to improve reults the authors give an account of a series of myringoplasties and specifically discuss the unsuccessful cases. By a slight alteration in the operative technique used in the series presented, the authors believe that some failures can be avoided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
