Shortness Of Breath In An Athlete - Page #4

Working Diagnosis:
Paradoxical Vocal Fold Motion (PVFM)

Bilateral injections of 3.75 MU botox into thyroarytenoid muscles.

Her voice remained severely breathy for 2 weeks and returned to baseline at 4 months after injections. She played the remainder of the soccer season with no issues.

Author's Comments:
It has been speculated the incidence of PVFM may be as high as 3% among collegiate athletes. A prospective evaluation of 167 patients diagnosed with intractable asthma showed that PVFM was the reason for treatment failure in 30% of cases. About one-third of patients exclusively exhibited PVFM; two-thirds suffered from both PVFM and asthma.
Conclusion: A healthcare professional with a high index of suspicion and an understanding of the signs and symptoms of PVFM can appropriately direct treatment.
