Human nasal blood vessels after permanent tracheostomy. Electron-microscopic study
Summary
Electron microscopy revealed capillary proliferation, venous congestion, and arteriolar contraction in the inferior turbinates of tracheostomized patients. These changes may relate to altered airflow patterns.
Area of Science:
- Otorhinolaryngology
- Pathology
- Microscopy
Background:
- Permanent tracheostomy alters upper airway physiology.
- The inferior turbinates are crucial for conditioning inhaled air.
Purpose of the Study:
- To investigate microcirculatory changes in the inferior turbinates of patients with permanent tracheostomy.
- To explore the relationship between altered airflow and observed histological variations.
Main Methods:
- Electron microscopy was used to examine biopsy specimens.
- Inferior turbinate tissue from 13 permanently tracheostomized patients was analyzed.
- Microscopic variations from normal tissue were systematically recorded.
Main Results:
- Observed variations included proliferation of capillaries.
- Venous congestion was a notable finding in the examined specimens.
- Arteriolar contraction was also recorded in the inferior turbinate tissue.
Conclusions:
- Permanent tracheostomy is associated with significant microcirculatory changes in the inferior turbinates.
- Altered airflow dynamics due to tracheostomy may contribute to these vascular alterations.
- Further research is warranted to understand the functional implications of these findings.
