Treatment with Hydroxyzine for Paradoxical Vocal Cord Dysfunction Abstract Paradoxical vocal cord dysfunction (VCD) is associated with several psychiatric conditions. Early intervention for ongoing anxiety problem is reported to be beneficial for patients in reducing symptoms of VCD. While there is extensive literature supporting the use of psychological interventions, the evidence for the use of medications is limited. The aim of this case report is to expand the evidence base about the medication options that can be used to treat VCD. We present a case with paradoxical vocal cord dysfunction who was successfully treated with hydroxyzine and psychoeducational intervention. Introduction Paradoxical vocal cord dysfunction (VCD), or paradoxical vocal-fold motion, (PVFM) is an insufficiently understood medical condition. It was first described by Patterson et al. in 1974, who named it Munchausen’s stridor 1 . It is a functional disorder of the vocal cords that leads to acute upper airway obstruction. 2 The presentation of the disease frequently mimics an episode of asthma as patients experience several similar symptoms including coughing, breathing problems, or inspiratory stridor 2 . The exact incidence and prevalence is not known as the condition is frequently misdiagnosed as asthma or other medical condition, or remains undiagnosed. Based on the available literature, certain trends are noted; there is greater prevalence in females 2, 4, 5 , and there is wide age range from 14.5 to 33 years for the occurrence of this disorder 2 . It is important to get a detailed physical history with physical examination and extensive work-up to rule out laryngeal causes of VCD such as paralysis, granulomas, or airway malacia. Once the organic causes have been ruled out, the triggers for PVFM may be broadly divided into psychological factors (accounting for 70% of the cases) and hypersensitivity reaction or other neurological disorders (accounting for the remaining 30% of the cases). 2,5 A multidisciplinary approach is essential to the management of PVFM/VCD dysfunction. Most teams have pulmonologists, otorhinolaryngologists, speech and language pathologists, and psychologists or psychiatrists. 5 From a psychiatric standpoint, it is important to do a comprehensive psychiatric evaluation taking into account and thoroughly investigating a history of clinical depression, history of abuse and personality disorder, and other somatoform disorders. Treatment for VCD begins with accurate diagnosis and subsequent family education about the disease. Alleviating symptoms is highly recommended before dealing with disease-related stressors because the new medical diagnosis and poor symptom control may easily cause significant anxiety. There is extensive evidence for several psychotherapeutic treatment options including biofeedback, hypnosis, and cognitive-behavioral therapy (CBT). However, there is dearth of literature regarding the use of medications for the management of PFVM. We present a case of paradoxical VCD that was successfully treated with hydroxyzine along with early psychoeducational intervention. Case Report A 16-year-old Caucasian male with history of seasonal allergies and sports-induced asthma presented to Emergency Department (ED) with intermittent choking spells, coughing, and difficulty swallowing. Patient reported that his symptoms had started as daily dry cough and then he had started experiencing choking episodes that lasted about a minute. During these episodes, patient felt he could not breathe and his throat was closing up. His symptoms had gradually worsened, and he had started to fear drinking and eating. After the first emergency visitation, esophagogastroduodenoscopy (EGD) was done that showed erosive changes and the presence of an esophageal stricture, which was dilated during EGD. Patient was diagnosed with Gastro esophageal reflux disease (GERD) and was started on omeprazole, sucralfate, and hyoscyamine. After the EGD, patient continued to avoid eating and drinking due to fear/feeling of food getting stuck. Patient then started to experience choking episodes at night time that woke him up; these episodes were accompanied by intense fear. Patient presented back to ED when Otolaryngologist/ENT was consulted and flexible scope done, which revealed healed pharyngeal lesions with significant inflammation and post cricoid edema. Vocal cords were mobile and the supraglottic anatomy was normal. Patient was sent home with reassurance. The following day, patient presented to a different ED with complaint of obstruction on the left side of his throat that he could feel when swallowing. Patient was admitted to general pediatrics for further investigation. He was put on clear liquid diet briefly and his upper gastrointestinal study revealed normal anatomy. Patient was then switched to regular diet and psychiatry was consulted for evaluation of anxiety as a potential contributor to his symptoms. During evaluation, patient endorsed somatic symptoms as well as symptoms of social anxiety. He stated he did not want to lie down supine on the bed, which could exacerbate his spasmodic episodes. He was interested in taking an as-needed medication to help him deal with his fear and so was started on hydroxyzine 25 mg at bedtime for anxiety and sleep. On follow-up the next day, patient stated he was able to sleep better with this medication and he only had one mild episode during the night. Speech therapist worked with the patient on breathing and relaxation techniques to help during laryngospasm episodes. During hospitalization, patient and family education with constant reassurance was provided by psychiatrist. Patient was discharged after three days of hospital stay. Patient was contacted over the phone a week after his discharge for follow up and he denied having any further episodes. Discussion Our patient received a new diagnosis of GERD with a prior history of sports-induced asthma and seasonal allergies. Even after being started on treatment of GERD, he continued to have intermittent choking episodes that would wake up him up from sleep, and his condition continued 274 • The Journal of the Arkansas Medical Society www.ArkMed.org
