Аннотация
OBJECTIVE: To report outcomes of a novel transcanal blind sac closure technique of the external auditory canal (EAC) with obliteration of the Eustachian tube orifice to treat CSF leaks after skull base surgery.
STUDY DESIGN: Clinical capsule report.
SETTING: University hospital.
PATIENTS: Ten patients who have undergone a transcanal blind sac closure of the EAC after skull base surgery to treat CSF leak between 2004 and 2012.
INTERVENTIONS: Transcanal blind sac closure of the EAC.
MAIN OUTCOME MEASURES: Resolution rate of postoperative CSF leak, time to final resolution of CSF leak, and complications.
RESULTS: The CSF leak resolution rate, with subsequent conservative management in some cases, is approximately 80%. One case of postsurgical pseudomeningocele was identified.
CONCLUSION: Transcanal blind sac closure of the EAC with obliteration of the Eustachian tube orifice provides a rapid and safe method to treat CSF leak after skull base surgery, without the need to reenter the original surgical wound or mastoid cavity.
