Nasal flaring in young children; Seesaw breathing in infants (where the chest and abdomen "seesaw" up and down; this is a sign of severe respiratory distress in an infant) A child exhibiting decreased work of breathing may be bradypneic (breathing too slowly) or too weak to engage the muscles required for inhalation.
There are however certain infants with conditions such as choanal atresia in which deaths have resulted from nasal obstruction. [20] In these cases, there are cyclical periods of cyanosis. The infant initially attempts to breathe through the nose, and is unable to; hypercapnia occurs, and many babies instinctively begin to cry. While crying ...
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
A CT scan showing evidence of the nasal cycle: the more patent airway is on the right of the image, the swollen turbinates congesting the left. The nasal cycle is the subconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals. This results in greater airflow through one nostril with ...
In the case of a labial-oral-nasal fistula, the plate may include an anterior upward extension to fully occlude the passageway running between the labial surface of the alveolus, alveolus, and nasal cavity. The plate may be constructed to include any congenitally missing teeth to improve articulation and appearance. Individuals who use palatal ...
The exact cause of adenoid hypertrophy in children remains unclear, but it is likely linked to immunological responses, hormonal factors, or genetic components. Adenoid hypertrophy is an immunological abnormality characterized by altered cytokine production, with children experiencing higher levels of proinflammatory cytokines.
The medial nasal process (nasomedial) on the inner side of each nasal pit merge into the intermaxillary segment and form the upper lip, crest, and tip of the nose. [1] The medial nasal processes merge with the maxillary prominences. The lateral nasal process from each side merge to form the alae of the nose. [1]
Stertor (from Latin stertere 'to snore') is a term first used in 1804 [2] to describe a noisy breathing sound, such as snoring. [3] [4] It is caused by partial obstruction of the upper airways, at the level of the nasopharynx or oropharynx.
