|January 1, 1976

Summary

This study details familial bilateral abductor vocal cord paralysis in a father and two sons. Early tracheostomy ensured normal development, unlike previous cases without surgical intervention.

Background:

Bilateral abductor vocal cord paralysis is a rare condition affecting the larynx.
Hereditary forms of this condition have been previously reported, often with associated developmental issues.

Observation:

A family presented with three affected members (father and two sons) exhibiting familial bilateral abductor vocal cord paralysis.
Onset of stridor varied between six months and nine years of age.
All affected individuals underwent tracheostomy for management.

Findings:

Affected individuals demonstrated normal development and intelligence following tracheostomy.
This contrasts with prior reports where non-surgical management was linked to mental retardation.

Implications:

Tracheostomy appears to be a critical intervention for preventing anoxia and ensuring normal development in familial bilateral abductor vocal cord paralysis.
Nonsurgical management of apparent vocal cord paralysis may carry risks of severe complications like anoxia due to laryngeal obstruction.
