Expansion of the clinical indications for ablative endoscopic endonasal approaches has behooved us to search for new reconstruction alternatives. We present the anatomic foundations of a novel anterior pedicled lateral wall flap (Hadad-Bassagaisteguy 2 or HB2 flap) for the vascularized reconstruction of anterior skull base defects.
Anatomic description. Feasibility study. Technical report
Using a cadaveric model, we investigated the feasibility of harvesting an anteriorly based mucoperiosteal flap from the lateral nasal wall. We then applied the techniques developed in the anatomical laboratory to reconstruct two patients with defects resulting from the endoscopic endonasal resection of esthesioneuroblastomas and one patient with an extensive meningoencephalocoele of the anterior cranial fossa.
HB2 flaps were harvested and transposed to reconstruct anterior skull base defects in cadaveric specimens, and subsequently, in three patients. The HB2 flap provided adequate coverage in the cadaveric model, as well as clinically in our three patients. Their postoperative healing was uneventful.
The HB2 flap is a feasible alternative for the reconstruction of anterior skull base defects in select patients.
消融性经鼻内镜手术适应证的扩展促使我们寻求新的重建方法。我们提出了一种新的前带蒂侧颅底皮瓣（Hadad-Bassagaisteguy 2 或 HB2 皮瓣），用于血管化重建前颅底骨缺损。
解剖学描述。可行性研究。技术报告
使用尸体模型，我们研究了从鼻腔外侧壁采集前颅底黏膜骨膜瓣的可行性。然后，我们将在解剖实验室中开发的技术应用于重建 3 例因经鼻内镜切除嗅神经母细胞瘤而导致的缺损患者和 1 例前颅窝广泛脑膜脑膨出的患者。
在尸体标本和随后的 3 例患者中成功采集并转移 HB2 皮瓣以重建前颅底骨缺损。在尸体模型中，HB2 皮瓣提供了充分的覆盖，在我们的 3 例患者中也具有临床效果。他们的术后恢复顺利。
HB2 皮瓣是一种可行的选择，可用于某些患者的前颅底骨缺损重建。
