Objectives: To determine the necessity of rigid endoscopy in the diagn
osis and management of laryngomalacia and its associated synchronous a
irway lesions (SALs), to analyze the incidence of SALs associated with
laryngomalacia and their significance, and to determine the need for
epiglottoplasty in management of laryngomalacia. Design: Retrospective
medical chart review. Setting: Tertiary care children's hospital. Pat
ients: Two hundred thirty-three patients with a primary diagnosis of l
aryngomalacia on flexible fiberoptic laryngoscopy treated at the Child
ren's National Medical Center, Washington, DC, from January 1, 1984, t
o June 30, 1994. Interventions: Evaluation and treatment of laryngomal
acia acid associated SAL by flexible fiberoptic laryngoscopy, radiogra
phic studies, rigid endoscopy, and other surgical procedures. Main Out
come Measures: Resolution of airway symptoms from laryngomalacia and a
ssociated SAL. Results: Ninety patients (38.6%) underwent rigid endosc
opy, and 12 patients (5.2%) required epiglottoplasty. Synchronous airw
ay lesions were discovered in 44 patients (18.9%). Eleven patients (4.
7%) had SALs that were considered clinically significant; nine (3.9%)
of these required surgical intervention. Conclusions: Rigid endoscopy
in evaluation of an infant with laryngomalacia is rarely necessary. Cl
inically significant SALs requiring surgical intervention are uncommon
. Surgical intervention for laryngomalacia also is rarely necessary.
