Analysis of Ciliary Abnormalities in Bronchiectasis

Infections, hereditary and congenital factors, and ciliary abnormalities can all cause bronchiectasis. Among these, bronchiectasis caused by ciliary abnormalities may be more difficult for people to understand and grasp, so I will share some information here. Cilia are present in the nasal cavity, trachea, bronchi, and even the esophagus, intestines, and many other hollow cavities. However, once ciliary abnormalities occur, because their locations and functions differ, they manifest as different phenomena and outcomes.

Ciliary abnormalities actually refer to abnormalities in ciliary structure and function, which result in poor ciliary movement, a greatly reduced clearance function, or even complete loss of it. From the initial onset of ciliary abnormalities to a more severe state, a "triad" of conditions emerges, including sinusitis, bronchiectasis, and situs inversus.

The sinusitis and other conditions in the "triad" manifest as recurrent episodes, and ciliary abnormalities can also easily cause bronchitis, pneumonia, otitis media, ectopic pregnancy, infertility, and hydrocephalus. In modern pathological analysis, after ciliary abnormalities occur, phenomena such as absent radial spokes, complete loss of ciliary dynein arms, missing central microtubules, and abnormal numbers of peripheral microtubules can be observed.

In terms of physical signs, after ciliary abnormalities occur, signs such as barrel chest, coarse breath sounds in both lungs, widened intercostal spaces, and scattered wheezing sounds may also appear; on CT examination, changes such as abnormal pulmonary texture structure, emphysema, and diffuse lesions in both lung fields can be seen; during tracheoscopy, tracheal mucosal congestion and a large amount of yellow viscous sputum may be present.
