Date of correction: July 27, 2010 Reason for correction: - Correction: ABSTRACT Details: Wrong : There are controversial reports about endolymphatic sac surgery (ESS) stating that simple mastoidectomy can obtain results as good as those by ESS. ESS does not last forever and demonstrates a high rate of recurrence due to closure of the endolymphatic sac (ES) after granulation or scar formation, which reduce the reliability of ESS.
It is considered that ESS would be used in more patients with MD if the problems of ESS could be reduced and its reliability improved.
We perform a retroauricular incision 1 cm posterior to that performed in regular tympanoplasty because anatomical landmarks which help locate the ES, such as the sigmoid sinus and the posterior cranial fossa dura mater, are easily exposed, and a wide working field of view can be obtained, leading to safe identification of the ES.
Moreover, we report a new technique to fix the flipped external wall of the ES using harvested temporal fascia to prevent restenosis and closure.

Abstract

There are controversial reports about endolymphatic sac surgery (ESS) stating that simple mastoidectomy can obtain results as good as those by ESS. ESS does not last forever and demonstrates a high rate of recurrence due to closure of the endolymphatic sac (ES) after granulation or scar formation, which reduce the reliability of ESS.
It is considered that ESS would be used in more patients with MD if the problems of ESS could be reduced and its reliability improved. We perform a retroauricular incision 1 cm posterior to that performed in regular tympanoplasty because anatomical landmarks which help locate the ES, such as the sigmoid sinus and the posterior cranial fossa dura mater, are easily exposed, and a wide working field of view can be obtained, leading to safe identification of the ES.
Moreover, we report a new technique to fix the flipped external wall of the ES using harvested temporal fascia to prevent restenosis and closure.
