View detailsAcute otitis media in children
Acute otitis media is an acute inflammation of the middle ear, often with a sudden onset within 48 hours. It can follow a common cold and may be accompanied by middle ear effusion. Depending on whether there is pus in the middle ear, it can be divided into acute non-suppurative otitis media and acute suppurative otitis media. Children are more susceptible to acute otitis media due to their lower immunity and the short, flat, and wide characteristics of their Eustachian tubes.

Chronic tonsillitis is a persistent, infectious inflammatory response of the tonsils, often caused by recurrent acute tonsillitis. This condition is common in preschool and school-aged children, with main symptoms including sore throat, dry throat, itchy throat, and irritating cough.
Pediatric secretory otitis media
Secretory otitis media, also known as serous otitis media, is a non-suppurative inflammatory disease of the middle ear characterized by middle ear effusion, intact tympanic membrane, and hearing loss. The occurrence of this disease is often related to Eustachian tube dysfunction. Due to the short, flat, and wide characteristics of the Eustachian tube in children, they are more susceptible to this disease than adults.

Congenital laryngeal web is caused by embryonic developmental disorders, leading to incomplete separation of the anterior parts of both vocal cords, forming a membranous connective tissue of uneven thickness, primarily affecting phonation and respiration.
View detailsSuppurative otitis media in children
Suppurative otitis media is a purulent inflammation of the middle ear mucosa caused by the invasion of pathogens into the middle ear. This disease is common in children because their organs are not yet fully developed, making the middle ear more susceptible to infection. The main symptoms of this disease include ear pain, tinnitus, hearing loss, and ear discharge.
View detailsCongenital choanal atresia
Congenital choanal atresia is a rare nasal malformation, which can be unilateral or bilateral, and is a familial genetic disease. Other multiple malformations may also be present. This disease is common in newborns. The ratio of unilateral to bilateral occurrence is approximately 1.6:1. The main symptoms include nasal obstruction, runny nose, dyspnea (or difficulty breathing during feeding), pharyngeal dryness due to mouth breathing, and olfactory dysfunction. In newborns with complete bilateral choanal atresia, severe respiratory distress, cyanosis (bluish discoloration of the skin and mucous membranes), or even complete obstruction may occur after birth.
