Symptom 9: Anosmia
Anosmia, or the inability to perceive odor, is a hidden challenge in infants with choanal atresia, primarily because it is difficult to assess in young children. However, it is an important symptom to consider, as the sense of smell is closely linked to the ability to taste and enjoy food, which can affect feeding behaviors.
The sense of smell plays a critical role in an infant’s developmental process, contributing to bonding and the experience of the environment. Anosmia in the context of choanal atresia occurs because the blocked nasal passages prevent odor molecules from reaching the olfactory receptors located high in the nose.
While the immediate implications of anosmia may not be as apparent as other symptoms, the potential long-term effects on the child’s sensory development and quality of life are significant. The lack of smell can lead to a decreased interest in feeding and an impaired sense of exploration and interaction with the world.
Detecting anosmia in infants often relies on indirect observations, such as a lack of response to strong odors or a decreased interest in feeding that cannot be attributed to other causes. It is a symptom that, when combined with other signs of choanal atresia, can aid in forming a complete picture of the infant’s condition.
Addressing anosmia involves treating the underlying choanal atresia. By opening the nasal passages, not only is breathing improved, but the sense of smell can be restored, enhancing the infant’s overall sensory experience and contributing to a richer engagement with their environment. (9)
