The velopharynx is a tridimensional muscular valve located between the oral and nasal cavities, consisting of the lateral and posterior pharyngeal walls and the soft palate, and controls the passage of air. Velopharyngeal insufficiency may take place when the velopharyngeal valve is unable to perform its own closing, due to a lack of tissue or lack of proper movement. Treatment options include surgical correction, prosthetic rehabilitation, and speech therapy; though optimal results often require a multidisciplinary approach for the restoration of both anatomical and physiological defect. We report a case of 56 year old male patient presenting with hypernasal speech pattern and velopharyngeal insufficiency secondary to cleft palate which had been surgically corrected 18 years ago. The patient was treated with a combination of speech therapy and palatal lift prosthesis employing interim prostheses in various phases before the insertion of definitive appliance. This phase-wise treatment plan helped to improve patient's compliance and final outcome.
咽腔是位于口腔和鼻腔之间的三维肌肉瓣膜,由侧咽壁和后咽壁以及软腭组成,控制空气的通过。当咽腔瓣膜由于组织缺乏或运动不当而无法正常关闭时,就会发生咽腔功能不全。治疗选择包括手术矫正、假体修复和言语治疗;尽管为了恢复解剖和生理缺陷,通常需要多学科方法来获得最佳效果。我们报告了一例 56 岁男性患者,因腭裂手术后 18 年出现鼻音过高和咽腔功能不全。该患者接受了言语治疗和腭提升假体联合治疗,在插入最终修复体之前的各个阶段使用了临时假体。这种分阶段的治疗计划有助于提高患者的依从性和最终结果。
