Medical Comorbidities for Paradoxical Vocal Fold Motion (Vocal Cord Dysfunction) in the Military Population

PVFM referrals of AD personnel of the US military are characterized by younger patients and a smaller female:male ratio as compared with non-AD patients. Based on the preponderance of men in the military, the number of females in the AD group remained disproportionately large. Multiple medical comorbidities were commonly documented by both groups; the only significant difference was a greater prevalence of asthma in the non-AD group. These data reinforce the need for appropriate differential diagnosis in all patients.
