Patients with early symptoms of bulbar amyotrophic lateral sclerosis (ALS) are usually referred to the otolaryngologist without a diagnosis. Careful examination of the speech quality and a physical exam, including the vocal cords, should be undertaken. The emotional state of the patient should be considered, and a diagnosis should not be offered before a neurologic consultation has been obtained. Patients with late symptoms of bulbar ALS almost always present with both significant speech and swallowing abnormalities. Evaluation can be difficult because many abnormalities are found on examination. Advanced progression of symptoms is a clear indication for rapid referral to a neurologist if a diagnosis has not already been made. Supportive and symptomatic care should be offered to the patient immediately. The University of Washington Neuromuscular Clinic for Speech and Swallowing Disorders has seen 600 new neurologic patients since 1986, 211 of whom were ALS patients. The introduction of percutaneous gastrostomy has greatly changed the management of ALS patients, and 75 patients have undergone this procedure (32% because of inadequate swallowing, 68% for declining vital capacity). Medical management to improve symptoms may be indicated before surgery. Surgical options for patients with late salivary presentation are uncommon and include removal of the submaxillary glands, tracheostomy, and laryngeal or salivary diversion procedures. Laryngectomy or laryngeal diversion procedures are only very rarely indicated. Although tracheostomy usually interferes with swallowing and worsens aspiration, it may rarely be indicated in patients with late airway presentation for glottic narrowing or artificial respiratory support. Symptomatic management of patients with bulbar ALS is usually best undertaken by a multidisciplinary clinic that can provide a physically and psychologically supportive environment.
患有延髓性肌萎缩侧索硬化症(ALS)早期症状的患者通常在未确诊的情况下被转诊至耳鼻喉科医生处。应仔细检查语音质量并进行包括声带检查在内的体格检查。应考虑患者的情绪状态,在获得神经科会诊意见之前不应做出诊断。患有延髓性ALS晚期症状的患者几乎总是同时出现明显的言语和吞咽异常。评估可能会很困难,因为检查中会发现许多异常情况。如果尚未做出诊断,症状的晚期进展是迅速转诊至神经科医生的明确指征。应立即为患者提供支持性和对症治疗。自1986年以来,华盛顿大学神经肌肉言语和吞咽障碍诊所已接待了600名新的神经科患者,其中211名是ALS患者。经皮胃造瘘术的引入极大地改变了ALS患者的治疗方式,已有75名患者接受了该手术(32%是因为吞咽不足,68%是因为肺活量下降)。在手术前可能需要进行改善症状的药物治疗。唾液分泌晚期患者的手术选择并不常见,包括切除颌下腺、气管切开术以及喉部或唾液改道手术。喉切除术或喉部改道手术仅在极少数情况下适用。尽管气管切开术通常会干扰吞咽并加重误吸,但在因声门狭窄或人工呼吸支持而出现气道晚期症状的患者中,可能很少需要进行气管切开术。延髓性ALS患者的对症治疗通常最好由多学科诊所进行,该诊所可以提供身体和心理上的支持环境。
