Conductive hearing loss

传导性听力损失
  • 文章类型: Journal Article
    当发生机械性阻塞和/或慢性炎症的鼻咽症状时,咽扁桃体的增生被认为是病理性的。慢性咽鼓管功能障碍可导致各种中耳疾病,如传导性听力损失,胆脂瘤,和复发性急性中耳炎.考试期间,应注意腺样体相(长脸综合征)的存在,具有永久张开的嘴和可见的舌尖。在严重症状和/或保守治疗失败的情况下,腺样体切除术通常在门诊进行。传统刮宫法仍然是德国既定的标准治疗方法。对于粘多糖症的临床证据,需要进行组织学评估。由于有出血的危险,术前出血问卷,这是每次儿科手术前必须做的,是指。尽管进行了正确的腺样体切除术,腺样体仍可能复发。出院回家前,应进行鼻咽部继发出血的耳鼻咽部检查,并获得麻醉清除。
    Hyperplasia of the pharyngeal tonsils is to be considered pathologic when nasopharyngeal symptoms of mechanical obstruction and/or chronic inflammation occur. Chronic Eustachian tube dysfunction can result in various middle ear diseases such as conductive hearing loss, cholesteatoma, and recurrent acute otitis media. During examination, attention should be paid to the presence of adenoid facies (long face syndrome), with a permanently open mouth and visible tip of the tongue. In the case of severe symptoms and/or failure of conservative treatment, adenoidectomy is usually performed on an outpatient basis. Conventional curettage remains the established standard treatment in Germany. Histologic evaluation is indicated for clinical evidence of mucopolysaccharidoses. Due to the risk of hemorrhage, the preoperative bleeding questionnaire, which is obligatory before every pediatric surgery, is referred to. Recurrence of adenoids is possible despite correct adenoidectomy. Before discharge home, otorhinolaryngologic inspection of the nasopharynx for secondary bleeding should be performed and anesthesiologic clearance obtained.

    Hyperplasia of the pharyngeal tonsils is to be considered pathologic when nasopharyngeal symptoms of mechanical obstruction and/or chronic inflammation occur. Chronic Eustachian tube dysfunction can result in various middle ear diseases such as conductive hearing loss, cholesteatoma, and recurrent acute otitis media. During examination, attention should be paid to the presence of adenoid facies (long face syndrome), with a permanently open mouth and visible tip of the tongue. In the case of severe symptoms and/or failure of conservative treatment, adenoidectomy is usually performed on an outpatient basis. Conventional curettage remains the established standard treatment in Germany. Histologic evaluation is indicated for clinical evidence of mucopolysaccharidoses. Due to the risk of hemorrhage, the preoperative bleeding questionnaire, which is obligatory before every pediatric surgery, is referred to.

    UNASSIGNED: Eine Hyperplasie der Tonsilla pharyngealis ist als Erkrankung zu bewerten, wenn durch mechanische Obstruktion und/oder chronische Entzündungen des Nasenrachens Krankheitssymptome auftreten. Aus einer chronischen Tubenventilationsstörung können unterschiedliche Mittelohrerkrankungen wie Schallleitungsschwerhörigkeit, Cholesteatom und rezidivierende akute Otitis media entstehen. Während der Inspektion ist das Augenmerk auf das Vorliegen einer Facies adenoidea mit dauerhaft offenem Mund und sichtbarer Zungenspitze zu legen. Bei starken Beschwerden und/oder frustranen konservativen Therapieversuchen erfolgt die Adenotomie in der Regel ambulant. Die herkömmliche Kürettage gilt nach wie vor als etablierte Standardmethode in Deutschland. Bei klinischen Hinweisen auf Mukopolysaccharidose ist die histologische Untersuchung indiziert. Wegen des Blutungsrisikos wird auf den Gerinnungsfragebogen, der obligat vor jedem operativen Eingriff im Kindesalter durchzuführen ist, hingewiesen. Trotz ordnungsgemäßer Adenotomie kann es zu einem Rezidiv der adenoiden Vegetationen kommen. Vor Entlassung in das häusliche Umfeld sollte eine HNO-ärztliche Kontrolle durch Inspektion des Rachens auf Nachblutung und eine anästhesiologische Freigabe erfolgen.

    这份临床共识文件涉及评估,选择,对于5岁以下被确定为单侧或双侧的儿童,非手术骨传导听力设备(BCHD)的安装注意事项,永久性导电或混合听力损失。患有严重单侧感觉神经性听力损失的儿童没有得到解决。该文件是根据儿科骨传导工作组的证据审查和共识制定的,它由来自北美的听力学家组成,他们有在儿童中使用BCHD的经验。该文件旨在为正在开发的儿科听力学实践领域提供临床指导,因此缺乏标准协议或指南。这项工作可以作为未来研究和临床贡献的基础,以支持前瞻性的儿科听力学实践。
    This clinical consensus document addresses the assessment, selection, and fitting considerations for non-surgical bone conduction hearing devices (BCHD) for children under the age of 5 years identified as having unilateral or bilateral, permanent conductive or mixed hearing losses. Children with profound unilateral sensorineural hearing losses are not addressed. The document was developed based on evidence review and consensus by The Paediatric Bone Conduction Working Group, which is composed of audiologists from North America who have experience working with BCHDs in children. The document aims to provide clinical direction for an area of paediatric audiology practice that is under development and is therefore lacking in standard protocols or guidelines. This work may serve as a basis for future research and clinical contributions to support prospective paediatric audiology practices.

  • 文章类型: Consensus Development Conference
    目的:为儿科患者听力损失的检查提供建议。
    方法:国际儿童耳鼻喉科小组成员的专家意见。
    结果:共识建议包括初步筛查和诊断以及感觉神经性检查,儿童传导性和混合性听力损失。共识声明讨论了基因检测和成像的作用,并提供了指导听力损失儿童检查的算法。
    结论:本文提供的建议可以指导听力损失儿童的检查。
    OBJECTIVE: To provide recommendations for the workup of hearing loss in the pediatric patient.
    METHODS: Expert opinion by the members of the International Pediatric Otolaryngology Group.
    RESULTS: Consensus recommendations include initial screening and diagnosis as well as the workup of sensorineural, conductive and mixed hearing loss in children. The consensus statement discusses the role of genetic testing and imaging and provides algorithms to guide the workup of children with hearing loss.
    CONCLUSIONS: The workup of children with hearing loss can be guided by the recommendations provided herein.

    OBJECTIVE: This study aimed to review current knowledge regarding implantation of the Vibrant Soundbridge floating mass transducer (FMT) at the round window (round window vibroplasty) as well as to form a consensus on steps for a reliable, stable surgical procedure.
    METHODS: Review of the literature and experimental observations by the authors.
    CONCLUSIONS: Round window (RW) vibroplasty has been established as a reliable procedure that produces good and stable results for patients with conductive or mixed hearing loss. The experience gained over the past few years of the authors\' more than 200 implantations has led to consensus on several key points: (1) a wide and bloodless access to the middle ear with facial nerve monitoring, (2) the careful and correct identification and exposure of the round window membrane, (3) a good setup for efficient energy transition of the FMT, namely, perpendicular placement of the FMT with no contact to bone and the placement of cartilage behind the FMT to create a preloaded \"spring\" function, and (4) 4 points of FMT fixation: a rim of the round window bony overhang left intact both anterior and posterior to the FMT, conductor link stabilization, and cartilage behind the FMT. In addition, the FMT should be covered with soft tissue.
