  • Title: Evaluation of spontaneous nasal cerebrospinal fluid leaks.
    Author: Wise SK, Schlosser RJ.
    Journal: Curr Opin Otolaryngol Head Neck Surg; 2007 Feb; 15(1):28-34. PubMed ID: 17211180.
    Abstract:
    PURPOSE OF REVIEW: Spontaneous nasal cerebrospinal fluid (CSF) leaks represent a distinct clinical entity that presents important diagnostic and therapeutic challenges. Recognition of the proper demographic group and presenting symptoms, as well as the radiologic features of this disease process, are integral to making the appropriate diagnosis. In addition, this patient group requires special perioperative and intraoperative considerations for suitable management. RECENT FINDINGS: Current literature echoes previously published success rates for endoscopic repair of CSF leaks at or above 90%. Success rates for closure of spontaneous CSF leaks, however, continue to be the lowest in comparison with other CSF leak etiologies. The increased failure rate for spontaneous CSF leak repair is likely due to the increased intracranial pressure present in this patient group. Patients with spontaneous CSF leaks are increasingly being recognized as belonging to a group inclusive of patients with benign intracranial hypertension and empty sella syndrome. SUMMARY: In this review, we highlight the demographic characteristics, clinical presentation and radiologic findings that distinguish spontaneous nasal CSF leak patients from those with other CSF leak etiologies. We also discuss perioperative measures advocated for patients with spontaneous nasal CSF leaks that may aid in the success of their surgical repair.
