Historically, surgeons reopened the prior retrosigmoid incision for transmastoid repair because the safety of creating a separate postauricular incision was uncertain, with concerns regarding wound breakdown and infection. However, limited data support this practice, and a focused mastoid incision may offer improved access and patient tolerance. This study evaluated wound healing outcomes following transmastoid repair using a new postauricular incision for persistent CSF leak after retrosigmoid surgery in patients without serviceable hearing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively reviewed 27 patients who underwent transmastoid repair for persistent postoperative CSF leak after retrosigmoid craniotomy for vestibular schwannoma (2000\u20132025). Demographics, operative details, timing of leak diagnosis and repair, wound complications, readmissions, antibiotic use, and culture results were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Median age was 48\u2009years (IQR 41\u201356); 67% were male, and mean BMI was 29.0\u2009kg\/m\n                      <jats:sup>2<\/jats:sup>\n                      . Mastoid obliteration was performed in 96%, with fat grafting in 93%. A new postauricular incision was used in all cases. Median time to leak diagnosis was 13\u2009days (IQR 4\u201379), and median time to repair was 2\u2009days (IQR 1\u20135). One patient (3.7%) developed a superficial wound abscess; no dehiscence or flap necrosis occurred. At median follow\u2010up of 34\u2009months (IQR 2.9\u201387.7), all wounds were healed. CSF leak recurred in two patients (7.4%) and three (11.1%) required reoperation.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A separate postauricular incision for transmastoid CSF leak repair was not associated with increased wound morbidity.
