Aim:
Laryngomalacia is the most common congenital anomaly of the larynx and is regarded as a process that resolves by the age of two years. The aim of the current study was to assess the prevalence of laryngomalacia beyond the age of 2 years, to describe its clinical characteristics and to identify risk factors.
Methods:
We retrospectively reviewed all bronchoscopies performed over a 3 year period. We compared the prevalence of laryngomalacia between children younger and older than 2 years of age. We also compared the presenting symptoms and co-morbidities between the two age groups.
Results:
Laryngomalacia was diagnosed in 167 (27 %) out of 618 pediatric bronchoscopies. Among the patients with laryngomalacia, 125 (75 %) were less than 2 years old and 42 (25 %) were more than 2 years old. Older children with laryngomalacia were more likely to present with snoring than stridor (44 % vs 24 %) and had more co-morbidities (48 % vs 22 %) than the younger group.
Conclusions:
Laryngomalacia is not rare in children older than 2 years of age. Co-morbidities are reported frequently in these children. Snoring is a more common symptom in this age group. Further complementary prospective studies are necessary to confirm our observations.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
