To evaluate the versatility of the collagen membrane as both drug carrier and biologic dressing material to cover the raw wounds created after the surgical excision of fibrotic bands in oral submucous fibrosis.
The study comprises of ten patients. The patients of age group 20 to 50 years were selected. The collagen is reconstituted by injecting with dexamethasone and placentrix solution leaving a small overlap on to the remaining mucous membrane and the graft is sutured. Preoperative and post operative assessment was done regarding the improvement in mouth opening, decrease in burning sensation, change in colour of oral mucosa and clinically grading the extent of lesion.
The results were found appreciable in seven patients while in the remaining three patients it showed relapse because of inadequate physiotherapy. All the ten patients were comfortable with intra oral collagen grafting. The collagen remained moist and supple intraorally, and remained in close contact with the underlying tissues, providing a strong mechanical barrier. The material was effective in attaining haemostasis, relieving pain and preventing extensive contracture.
In this study of short duration, the nature of collagen membrane was observed as both biological dressing material and drug carrier. It was found as a very suitable alternative to the other graft material mentioned for the repair of defects in the mucous membrane created by surgical excision of fibrous bands in oral submucous fibrosis.
评估胶原膜作为药物载体和生物敷料材料的多功能性,以覆盖口腔黏膜下纤维化患者手术切除纤维条索后形成的创面。
本研究包括10名患者。选取年龄在20至50岁之间的患者。通过注射地塞米松和胎盘提取物溶液来重构胶原,使其在剩余黏膜上稍有重叠,然后缝合移植物。对患者术前和术后的开口度改善情况、烧灼感减轻情况、口腔黏膜颜色变化以及病变程度进行临床分级评估。
7名患者的结果令人满意,而其余3名患者因物理治疗不足出现复发。所有10名患者对口腔内胶原移植均感到满意。胶原在口腔内保持湿润和柔软,与下方组织紧密接触,提供了强大的机械屏障。该材料在实现止血、缓解疼痛和防止广泛挛缩方面有效。
在这项短期研究中,观察到胶原膜兼具生物敷料材料和药物载体的性质。它被发现是修复口腔黏膜下纤维化手术切除纤维条索后造成的黏膜缺损的一种非常合适的替代其他移植材料的选择。
