Abstract

Squamous cell carcinoma, arising in nasal mucosa, is rare and is estimated to be less than 1% of cases of head and neck cancer. Surgical treatment for aggressive intranasal squamous cell carcinoma (SCC) requires a multidisciplinary team approach to ensure optimal patient outcomes. Surgical procedures for the removal of intranasal malignancies may include rhinectomy, palatectomy, and maxillectomy. These procedures leave patients with significant facial defects. However, in rare cases surgery may preserve nasal skin. In these cases, one needs to reconstruct nasal lining and support. Complex nasal reconstruction is often staged and therefore may delay complementary oncologic therapy [1,2]. As a rule, we would initially like to keep reconstruction as simple as possible, while preserving valuable tissue from scaring and shrinkage due to radiotherapy. Lining the nose with a full-thickness skin graft may serve this purpose well [3,4]. In order to assist skin graft adherence in the immediate post operative stage as well as prevent later shrinkage, we constructed a nasal obturator.
技术革新:术中鼻内壁植皮闭孔
发生于鼻黏膜的鳞状细胞癌是罕见的,估计在头颈癌病例中占不到1%。侵袭性鼻内鳞状细胞癌(SCC)的手术治疗需要一个多学科的团队来确保最佳的患者预后。鼻内恶性肿瘤切除的外科手术包括鼻切除术、腭切除术和上颌切除术。这些手术会给病人留下严重的面部缺陷。然而,在极少数情况下,手术可以保留鼻腔皮肤。在这些情况下,需要重建鼻衬和支撑。复杂的鼻腔重建通常是分阶段进行的,因此可能会延迟补充肿瘤治疗[1,2]。一般来说,我们一开始希望重建尽可能简单,同时保护有价值的组织不因放射治疗而受到惊吓和萎缩。在鼻子内壁进行全层皮肤移植可以很好地达到这一目的[3,4]。为了帮助植皮在术后立即粘附,并防止后期收缩,我们构建了一个鼻闭孔。
