In cases of severe laryngomalacia, laser division of the aryepiglottic
folds (AEFs) or endoscopic supraglottoplasty may be an ineffective so
lution. Failure of this technique is rare and the reasons for failure
are not well established. The purpose of this study was to describe th
ose cases of laryngomalacia in which endoscopic treatment did not reve
rse the clinical situation. We introduce the concept of discoordinate
pharyngolaryngomalacia (DPLM). DPLM was defined as severe laryngomalac
ia with complete supraglottic collapse during inspiration, without sho
rtened AEFs or redundant mucosa, and with associated pharyngomalacia,
Twenty-seven of 82 children with severe laryngomalacia presented a DPL
M. Endoscopic treatment was performed in 16 children and the surgical
procedure was inadequate to reverse the clinical problem in these pati
ents. In 10 children correction of additional sites of obstruction was
required (uvulopharyngopalatoplasty, surgery of choanal atresia, aort
opexy). Tracheostomy was necessary in 13 children. Bi-level positive a
irway pressure (BiPAP) was used successfully in 2 children and tracheo
tomy was avoided. Treatment still needs to be better defined. (C) 1997
