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.
Clinical capsule report.
University hospital.
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.
Transcanal blind sac closure of the EAC.
Resolution rate of postoperative CSF leak, time to final resolution of CSF leak, and complications.
The CSF leak resolution rate, with subsequent conservative management in some cases, is approximately 80%. One case of postsurgical pseudomeningocele was identified.
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.
