Acquired Flaccid Larynx: A Case Report Supporting the Neurologic Theory of Laryngomalacia

Aspiration following CO2 laser-assisted supraglottoplasty

“…Reflux was suspected to play a role in disease severity, based on clinical findings at bronchoscopy, in 79% of the patients in this study. This is consistent with the literature [10,11,14].…”

Brainstem dysfunction: a possible neuroembryological pathogenesis of isolated Pierre Robin sequence

“…Finally, laryngoscopy demonstrated impairment of the supraglottis dynamics, with anteroposterior pharyngolaryngeal collapse that differs from usual laryngomalacia with posterior mucosal aspiration and lateral collapse of the epiglottis. This laryngeal aspect resembles that found in neurogenic situations [4,7]. It is not the consequence of the obstructive glossoptosis, since we observed this laryngeal aspect in PRS children with minor glossoptosis but not in children with other upper airway obstructions (no PRS), in particular nasal obstruction (Manach, personal data).…”

Acquired laryngomalacia: Resolution after neurologic recovery

“…It is interesting that Peron's seven patients demonstrated only aryepiglottic fold collapse (type I laryngomalacia) and that Woo's eight patients revealed only epiglottic prolapse (type IV laryngomalacia). To date only one patient has been reported to manifest more than one site of involvement 4 . Our two patients with neurodegenerative diseases exhibited type IV laryngomalacia only.…”

“…This assisted with pulmonary hygiene and ventilatory support. Endolaryngeal procedures to alter the involved laryngeal structures have met with good success 1‐5,11 but in our experience may be avoided if ALM is allowed to resolve.…”
