Satchmo's syndrome

Satchmo's syndrome is a disorder caused by rupture of the orbicularis oris muscle in trumpet players, leading to loss of the ability to produce high notes萨奇莫综合征是一种由小号手口轮匝肌破裂引起的疾病，导致无法产生高音。

The syndrome is named after the nickname of Louis Armstrong, the trumpet player from New Orleans, because it fits with the symptoms he experienced in 1935该综合征以来自新奥尔良的小号手路易斯·阿姆斯特朗的昵称命名，因为它符合他在1935年经历的症状。

The condition is an occupational disorder of brass musicians, and may be partially reversed by rest or corrected by surgery该病是铜管音乐家的职业性疾病，可通过休息部分逆转或通过手术矫正。

• Recognition of the condition has been important for the medical care of professional musicians and the prevention of career-ending injuries对该病的认识对于专业音乐家的医疗护理和预防终结职业生涯的损伤很重要。^[1]

Epidemiology

• Satchmo's syndrome is rare, and its exact incidence among brass musicians is not well established萨奇莫综合征罕见，其在铜管音乐家中的确切发病率尚未充分确定。^[1]
• The condition predominantly affects trumpet players, though other high brass instrumentalists may be affected该病主要影响小号手，尽管其他高音铜管演奏者也可能受累。^[1]
• Both sexes may be affected, and the condition occurs in musicians of all ages who play high brass instruments两性均可受累，该病发生在演奏高音铜管乐器的各年龄段音乐家中。^[1]
• Risk factors include prolonged and intensive playing, particularly of high notes, and inadequate rest between performances危险因素包括长时间和高强度演奏，特别是高音，以及演出之间休息不足。^[1]
• The condition is more common in professional musicians who practise and perform intensively over many years该病在多年高强度练习和演出的专业音乐家中更常见。^[1]

Pathophysiology

• Satchmo's syndrome results from the rupture of the orbicularis oris muscle, which is subjected to repeated forceful contraction during trumpet playing萨奇莫综合征源于口轮匝肌的破裂，该肌肉在小号演奏期间受到反复强力收缩。^[1]
• To produce the right music, the trumpet player must exert strength and produce vibrations of the lip, which can lead to rupture of the lip musculature为了产生正确的音乐，小号手必须施加力量并产生唇部振动，这可能导致唇部肌肉组织破裂。^[1]
• Due to the muscle rupture, there is lengthening of the circumference of the orbicularis oris, and it fails to exert normal strength由于肌肉破裂，口轮匝肌的周长延长，无法施加正常力量。^[1]
• As a result, the trumpet player cannot produce high musical notes, which require greater lip tension and control结果，小号手无法产生高音，这需要更大的唇部张力和控制。^[1]
• The condition may also involve fibrosis and scarring of the muscle, which further impairs its function该病还可能涉及肌肉的纤维化和瘢痕形成，进一步损害其功能。^[1]
• Overuse and inadequate recovery time are key factors in the development of the muscle rupture过度使用和恢复时间不足是肌肉破裂发展的关键因素。^[1]

Clinical features

• The cardinal feature is the inability to produce high musical notes, with reduced range and endurance of the trumpet playing主要特征是无法产生高音，小号演奏的音域和耐力降低。^[1]
• Musicians may experience lip fatigue, discomfort and a sense of weakness in the embouchure音乐家可能经历唇部疲劳、不适和吹嘴无力感。^[1]
• The condition may develop gradually with overuse or acutely after a particularly demanding performance该病可能随过度使用逐渐发展，或在特别高要求的演出后急性发生。^[1]
• Physical examination may reveal asymmetry or thinning of the orbicularis oris muscle体格检查可能揭示口轮匝肌的不对称或变薄。^[1]
• Complications include loss of playing ability, which can be career-threatening for professional musicians并发症包括演奏能力丧失，对专业音乐家可能是职业生涯威胁。^[1]
• Some musicians may develop compensatory habits that can lead to further injury or other embouchure disorders一些音乐家可能形成代偿习惯，可能导致进一步损伤或其他吹嘴疾病。^[1]

Diagnosis

• Diagnosis is based on the clinical history of trumpet playing and the characteristic inability to produce high notes诊断基于小号演奏的临床病史和无法产生高音的特征性表现。^[1]
• Physical examination of the orbicularis oris muscle may reveal asymmetry or weakness口轮匝肌的体格检查可能揭示不对称或无力。^[1]
• Imaging studies such as ultrasound or MRI may be used to assess the integrity of the muscle in some cases在某些病例中，超声或 MRI 等影像学研究可用于评估肌肉的完整性。^[1]
• The differential diagnosis includes other embouchure disorders such as focal dystonia and overuse syndromes鉴别诊断包括其他吹嘴疾病，如局灶性肌张力障碍和过度使用综合征。^[1]
• Referral to an otolaryngologist or a physician experienced in musicians' medicine is recommended for suspected cases对疑似病例建议转诊至耳鼻喉科医生或有音乐家医学经验的医生。^[1]
• No specific laboratory tests are required for the diagnosis of Satchmo's syndrome萨奇莫综合征的诊断不需要特定的实验室检查。^[1]

Management

• Management begins with rest from playing for several weeks to months, which may allow partial reversal of the condition管理从停止演奏数周至数月开始，可能允许该病部分逆转。^[1]
• Surgical repair of the orbicularis oris muscle may be performed, and musicians can return to their pre-injury playing level after surgery可进行口轮匝肌的手术修复，音乐家在手术后可以恢复到受伤前的演奏水平。^[1]
• Embouchure retraining with the guidance of a teacher or therapist may help prevent recurrence在教师或治疗师指导下进行吹嘴再训练可能有助于预防复发。^[1]
• Gradual return to playing with appropriate warm-up and rest periods is important after recovery恢复后逐渐恢复演奏并适当热身和休息很重要。^[1]
• Preventive measures include adequate rest, proper technique and avoiding excessive high-note playing预防措施包括充分休息、正确技术和避免过度高音演奏。^[1]
• The prognosis is generally good, with many musicians recovering fully after rest or surgery预后通常良好，许多音乐家在休息或手术后完全康复。^[1]

Research and controversies

• The optimal management of Satchmo's syndrome, particularly the indications for surgery, is an area of ongoing discussion萨奇莫综合征的最佳管理，特别是手术指征，是持续讨论的领域。^[1]
• The role of embouchure retraining and preventive strategies in reducing the incidence of the condition is an area of active research吹嘴再训练和预防策略在降低该病发生率中的作用是活跃的研究领域。^[1]
• The relationship between Satchmo's syndrome and other musicians' dystonias and overuse injuries is not well characterized萨奇莫综合征与其他音乐家肌张力障碍和过度使用损伤之间的关系尚未充分描述。^[1]
• Given the rarity of the condition, most knowledge comes from case reports and small case series鉴于该病的罕见性，大部分知识来自病例报告和小病例系列。^[1]
• Further research is needed to understand the pathophysiology and develop evidence-based prevention and management guidelines需要进一步研究以理解病理生理学并制定循证预防和管理指南。^[1]
