The exact pathophysiology is still not well understood. Our objective was to investigate whether laryngomalacia is an inflammatory disease, focusing on the possible role of vitamin D.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Case\u2010control study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Sixty Egyptian infants and 60 mothers were included in this study. They were divided into four equal groups (n = 30 for each): infants with laryngomalacia (LM\u2010infants), control infants (C\u2010infants), mothers of the infants with laryngomalacia (LM\u2010mothers), and mothers of the control infants (C\u2010mothers). Laryngoscopy was performed and serum 25\u2010hydroxyvitamin D (25[OH]\u2010vitamin\u2010D) and interleukin 6 (IL\u20106) were estimated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Significant increase of serum IL\u20106 associated with a significant decrease in serum 25(OH)\u2010vitamin D was observed in the LM\u2010infants compared to the C\u2010infants (<jats:italic>P<\/jats:italic> &lt; .001 for both).

Laryngomalacia could be an inflammatory disease due to 25(OH)\u2010vitamin D deficiency as evidenced by the high level of IL\u20106.
