Otogenic cerebrospinal fluid rhinorrhea: A new technique for closure of cerebrospinal fluid leak

Objective: To describe a new technique for control of cerebrospinal fluid ( CSF) rhinorrhea and to review alternative approaches. Study Design: Five cases and literature review. Setting: Tertiary referral center. Patients: Five case study patients. Intervention: Surgical. Main Outcome Measure: Control of CSF rhinorrhea. Results: CSF rhinorrhea can be controlled through eustachian tube ligation in the nasopharynx, distal to all known pathways through which CSF leaks ma y occur from the temporal bone into the eustachian tube. Conclusion: Transoral eustachian tube ligation appears to be a safe and eff ective alternative to other techniques fur controlling CSF rhinorrhea and s hould be included in the otologist's repertoire.
