Summary
Olfactory dysfunction is common in neurological patients but often overlooked. This review covers olfactory system anatomy, physiology, and measurement, aiding diagnosis and treatment for improved quality of life.
Area of Science:
- Neuroscience
- Otorhinolaryngology
Background:
- Olfactory disturbances are prevalent in neurological and neurosurgical patients.
- Olfactory function is infrequently assessed in neurosurgical settings, with limited resources like "smell bottles".
Purpose of the Study:
- To systematically review recent advances in human olfactory function.
- To discuss the diagnosis, causes, and treatment of smell disorders in neurosurgical contexts.
Main Methods:
- Systematic review of current literature on olfactory anatomy and physiology.
- Discussion of olfactory coding and measurement techniques.
- Analysis of surgical impacts and recovery patterns for olfactory disorders.
Main Results:
- Olfactory system anatomy, physiology, and coding are complex.
- Various surgical procedures pose risks to the olfactory system.
- Smell disorders have diverse causes, symptoms, and recovery trajectories.
Conclusions:
- Accurate diagnosis of olfactory dysfunction can improve patient management and quality of life.
- Standardized assessment and updated resources are needed in neurosurgical units.
- Understanding olfactory system recovery is crucial for treatment strategies.
