Objectives: Sigmoid sinus (SS) compression and injury is associated with postoperative SS occlusion and corresponding morbidity. Leaving the SS skeletonized with a thin boney protection during surgery might be favorable. This study quantifies the effect of the SS position on the operative exposure in the translabyrinthine approach and assess the feasibility of retracting a skeletonized SS. Methods: Twelve translabyrinthine approaches were performed on cadaveric heads with varying SS retraction: skeletonized stationary (TL-S), skeletonized posterior retraction (TL-R), and deskeletonized collapsing of the sinus (TL-C). High-definition 3D reconstruction of the resection cavity was obtained. The primary outcome, ‘surgical freedom’ (mm2), was the area at the level of the craniotomy from which the internal acoustic porus could be reached in an unobstructed straight line. Secondary outcomes include the ‘exposure angle’, ‘angle of attack’ and pre-sigmoid depth. Results: During TL-R, surgical freedom increased by a mean of 41% (range: 9-92%, SD: 28) when compared to no retraction (TL-S). Collapsing the SS in TL-C provided a mean increase of 52% (range: 19-95%, SD: 22) compared to TL-S. In most cases the exposure is the greatest when the sigmoid sinus is collapsed. In 40% of the specimens, the provided exposure while retracting (TL-R) instead of collapsing (TL-S) the sinus is equal or greater than 50% of other specimens in which the sinus is collapsed. Conclusions: In cases with favorable anatomy, a translabyrinthine resection in which the skeletonized sigmoid sinus is retracted, provides comparably sufficient exposure for adequate and safe tumor resection.
