Abstract
20 patients who had undergone microvascular decompression for the treatment of “idiopathic” trigeminal neuralgia (9 cases), hemifacial spasm, (7 cases), glossopharyngeal neuralgia (3 cases) and paroxysmal vertigo and tinnitus (1 case) were followed up for 25 months on average. Permanent relief of symptoms was observed in 19 (95%), with sparing of cranial nerve function. Analysis of the clinical data shows that the patients described in the present series did not differ from those considered to suffer from “idiopathic” cranial nerve dysfunction syndromes.
The importance of vascular cross compression as etiological factor in such conditions is stressed and the pathophysiology discussed. The term “cryptogenic” applied to trigeminal neuralgia or hemifacial spasm thus needs revising. Lastly, the indications of microvascular decompression in the treatment of “cryptogenic” cranial nerve dysfunction syndromes are defined.
Sommario
Venti pazienti affetti da forme “essenziali” di nervralgia trigeminale (9 casi), emispasmo facciale (7 casi), nevralgia glosso-faringea (3 casi) e vertigine e tinnito parossistici (1 caso), operati di decompressione microvascolare, sono stati riesaminati ad una distanza media dall'intervento di 25 mesi. In 19 pazienti (95%) si è osservata la completa guarigione, in assenza di deficit funzionali a carico dei nervi cranici interessati.
In base ai dati clinici e neuroradiologici, i pazienti qui descritti non sono differenziabili dal gruppo generale di malati con forme “idiopatiche” di nevralgia od emispasmo.
Viene sottolineata l'importanza del fattore compressivo vascolare nel determinismo delle disfunzioni “essenziali” dei nervi cranici, e se ne discutono le interpretazioni fisiopatologiche. Si suggerisce quindi la necessità di rivedere il concetto di “idiopatico” applicato a tali condizioni morbose. Infine vengono definite le precise indicazioni ed il ruolo della decompressione microvascolare nella terapia della patologia “essenziale” dei nervi cranici.
