Objective : Neurilemomas are classically described as fusiform tumors that eccentrically displace the undisturbed neural fascicles. The authors seek to clarify the relationship of cervical neurilemomas to their nerve of origin and assess the functional outcome of surgical extirpation. Study Design : A retrospective review of clinical, intraoperative, and histopathologic data of six patients with cervical extracranial neurilemomas. Methods : Additional histochemical staining of the pathologic specimens was performed to evaluate the tumor for neurites. A comprehensive literature review of cervical neurilemoma cases and meta‐analysis of clinical outcomes in these cases were performed. Results : In the series of five consecutive cervical neurilemomas, only one was an eccentric mass pushing the undisturbed nerve aside. In the five other cases, excision of the neurilemoma required complete nerve excision. Neural elements traveling through the central portions of the tumor were clearly demonstrated histologically. Collective analysis of the literature on cervical neurilemomas revealed that although some cases allow nerve preservation, preservation of function is frequently poor. Conclusions : This experience and that reported in the literature suggest that it is frequently impossible to preserve the function of the nerve of origin with surgical treatment of cervical neurilemomas.
