We present the anatomic and cadaveric foundations for novel modifications of the occipital galeopericranial flap for reconstruction of ventral skull base defects.
Anatomic description.
Using cadaveric dissections and measurements, we investigated the feasibility of transposing pedicled occipital galeopericranial flaps into the nasal cavity and skull base. Two fresh and five preserved human specimens were dissected.
Pedicled occipital flaps were transposed into the nasal cavity via a transparapharyngeal-transpterygoid corridor into the nasopharynx. It was demonstrated that the pedicled occipital galeopericranial flap reaches the anterior skull base.
Pedicled occipital flaps transposed into the nasal cavity can reach the anterior skull base and provide another option for vascularized reconstruction in selected patients.
为重建颅底前下部缺损，我们提出枕肌-颞肌筋膜瓣的新改良方式，并对其解剖学和尸体学基础进行阐述。
解剖学描述。
通过尸体解剖和测量，我们研究了带蒂枕肌-颞肌筋膜瓣经咽旁-翼突入路转位至鼻腔和颅底的可行性。共解剖了 2 个新鲜和 5 个防腐标本。
带蒂枕肌筋膜瓣经咽旁-翼突入路转位至鼻腔，穿过鼻咽部。研究表明带蒂枕肌-颞肌筋膜瓣可到达颅前窝底。
带蒂枕肌筋膜瓣经鼻腔转位可到达颅前窝底，为特定患者提供了另一种血运重建的选择。
