研究目的:

1. 主要目的: 开展新技术应用:在我院耳鼻喉科建立血小板富集血浆(Platelet-Rich Plasma,PRP)声带注射治疗的标准化操作流程,用于治疗老年喉、声带瘢痕、声带沟及声带萎缩等良性咽喉嗓音病变,探索其在声带组织修复与功能重建中的临床应用价值。 2. 次要目的: (1)系统验证安全性与有效性:通过前瞻性临床观察,系统评估 PRP 声带注射的安全性及疗效,重点分析其在改善患者声音质量(包括 VHI-10 评分、声学分析参数及动态喉镜声带振动表现)方面的作用机制与临床效果。 (2)形成可推广的诊疗规范:完成 70–100 例患者的临床研究病例收集与随访,基于疗效数据与操作经验,制定标准化、可复制、可推广的 PRP 声带注射诊疗流程和临床应用规范,为该项技术在我院及区域内的推广应用奠定基础。  

Objectives of Study:

Primary Objective: To implement a novel clinical technique by establishing a standardized operating procedure for platelet-rich plasma (PRP) vocal fold injection in the Department of Otolaryngology of our hospital. This technique is intended for the treatment of benign laryngopharyngeal voice disorders, including presbylaryngis, vocal fold scarring, sulcus vocalis, and vocal fold atrophy, and to explore its clinical value in vocal fold tissue repair and functional reconstruction. Secondary Objectives: (1) To systematically evaluate the safety and therapeutic efficacy of PRP vocal fold injection through a prospective clinical observational study, with particular emphasis on its effects on improving voice quality, as assessed by Voice Handicap Index-10 (VHI-10) scores, acoustic analysis parameters, and dynamic laryngoscopic assessment of vocal fold vibration. (2) To complete the collection and follow-up of 70–100 clinical cases and, based on therapeutic outcomes and procedural experience, to establish a standardized, reproducible, and generalizable diagnostic and therapeutic protocol for PRP vocal fold injection, thereby providing a foundation for the implementation and dissemination of this technique within our institution and the surrounding region.

Inclusion criteria

1.Age requirement: >=18 years; with full civil capacity and able to comply with follow-up and assessments. 2.Confirmed diagnosis: Diagnosed by videolaryngostroboscopy (dynamic laryngoscopy) as having at least one of the following benign conditions: vocal fold scar, sulcus vocalis, vocal fold atrophy, presbylaryngis, or other benign vocal fold disorders causing impaired vocal fold vibration (e.g., mild inflammatory lesions). 3.Clinical symptoms: Presence of functional voice impairment such as hoarseness, vocal fatigue, reduced vocal loudness, or abnormal voice quality; VHI-10 indicates moderate to severe voice handicap. 4.Previous treatment history: Prior treatments such as vocal fold surgery and/or vocal fold injection are allowed if symptoms have not significantly improved; no laryngeal surgery, injection, or other invasive laryngeal procedures within the past 3 months. 5.General condition: Generally healthy without severe systemic disease, and able to tolerate local injection procedures.

排除标准:

排除标准:近 3 个月内曾行喉部手术/注射增粗;活动性喉部感染/炎症;凝血障碍、血小板减少/功能异常;自身免疫病、肿瘤、重度肝病、明显呼吸功能受限;对利多卡因/酰胺类麻药/牛源制品过敏;喉部合并病影响疗效判读(如明显震颤/肌张力障碍);妊娠,则不宜参加本研究。

Exclusion criteria:

Exclusion criteria: Any laryngeal surgery or vocal fold augmentation injection within the past 3 months; active laryngeal infection/inflammation; coagulopathy, thrombocytopenia, or platelet function disorders; autoimmune disease, malignancy, severe liver disease, or significant respiratory functional limitation; allergy to lidocaine, amide-type local anesthetics, or bovine-derived products; coexisting laryngeal conditions that may confound efficacy assessment (e.g., marked vocal tremor or laryngeal dystonia/muscle tension dysphonia); pregnancy—pregnant individuals are not eligible to participate in this study.
