What is the recommended treatment for globus pharyngeus?

Treatment of Globus Pharyngeus

The recommended treatment for globus pharyngeus is a multimodal approach prioritizing cognitive-behavioral therapy (CBT)-based psychoeducation and speech-language therapy, with consideration of neuromodulators (SSRIs or low-dose amitriptyline) for refractory cases, while proton pump inhibitors show limited efficacy despite widespread use. 1, 2

Initial Management Approach

Patient Education and Reassurance

• Provide clear explanation that globus is a functional disorder characterized by reversible changes in laryngeal function rather than structural pathology 1
• Explain that symptoms represent a sensation of a foreign body, tightening, or choking feeling in the throat that is typically more obvious between meals and improves with eating 1
• Emphasize the benign nature when red flags are absent, as malignancy is vanishingly rare without alarm symptoms 3, 4
• Address the psychological stress component, noting that stress often exacerbates symptoms during periods of high emotional intensity, though psychiatric disorders may be an outcome rather than a cause 1

Speech-Language Therapy (First-Line Treatment)

Speech-language therapy should be the primary therapeutic intervention, focusing on:

• Cognitive-behavioral strategies to identify and challenge maladaptive beliefs such as "food will stick in my throat" or "my throat feels tight and narrow" 1
• Address avoidance behaviors including reduced food intake, texture modifications, altered head postures, eating slowly with raised bodily tension, and social withdrawal 1
• Recommend positive self-statements during swallowing such as "my throat feels easy" and "this swallow is easy" 1
• Provide education about the physiology of anxiety and the anxiety arousal curve, emphasizing the importance of avoiding avoidance 1
• Redirect patient focus away from throat sensations to reduce hypervigilance to bodily functions 1

Pharmacological Management

Neuromodulators (Second-Line for Refractory Cases)

Consider SSRIs or low-dose amitriptyline for patients who do not respond to behavioral interventions 1

• A 2023 randomized controlled trial demonstrated that neuromodulators (flupenthixol 0.5 mg + melitracen 10 mg) provided significant reduction in Glasgow Edinburgh Throat Scale scores compared to PPIs 2
• Gabapentin should be considered for patients who do not respond or only partially respond to reflux management, with 66% of patients reporting improvement in one study 5
• Eight of 14 patients who failed aggressive reflux management improved with gabapentin 5
• Important caveat: Neuromodulators cause more adverse events than CBT, making behavioral therapy preferable when effective 2

Proton Pump Inhibitors (Limited Evidence)

PPIs have limited efficacy despite widespread use and should not be first-line treatment 2, 6

• Provide information and advice to reduce acid reflux if gastroesophageal reflux disease is suspected as a contributing factor 1
• A 2023 RCT showed PPIs (omeprazole 20 mg) provided minimal reduction in symptom scores compared to CBT and neuromodulators 2
• Despite 67% of patients showing partial or complete response to aggressive reflux management in one study, there is little high-quality evidence supporting PPI efficacy 5, 6
• Consider a therapeutic trial only when reflux symptoms are prominent 7

Treatment Efficacy Evidence

The highest quality recent evidence (2023 RCT) demonstrates:

• CBT reduced Glasgow Edinburgh Throat Scale scores by 6.46 ± 8.56 points versus 0.21 ± 5.42 for PPIs (p = 0.031) 2
• Neuromodulators reduced scores by 6.92 ± 9.85 points versus 0.21 ± 5.42 for PPIs (p = 0.036) 2
• Both CBT and neuromodulators were equally effective, with CBT preferred due to fewer adverse effects 2
• Overall, 77% of patients showed improvement with appropriate treatment 5

Important Clinical Considerations

Distinguish from True Dysphagia

• Globus must be differentiated from dysphagia, though 20% of patients with functional dysphagia experience globus sensation with swallowing 1
• Positive signs of functional dysphagia include inability to swallow without drooling or excessive oral secretions, or inability to control anything in the mouth but ability to spit saliva into a cup 1

Address Quality of Life Impact

• Recognize that globus can lead to unintended weight loss, social withdrawal, anxiety, panic, and depression with quality of life impacts similar to head and neck cancer patients 1
• Fear of choking is common and requires specific behavioral intervention 1

Comorbid Conditions

• Globus commonly co-occurs with functional voice disorders, chronic cough, throat clearing, and dysphonia with pharyngolaryngeal tension 1
• Treatment of a single communication problem may result in resolution of all communication symptoms 1

Evidence Limitations

Critical gap: There have been no randomized controlled trials specifically targeted at functional dysphagia as opposed to globus 1

The evidence base remains limited, with the 2023 RCT by 2 representing the highest quality comparative effectiveness study available, though sample size was modest (n=40 completers).
