Olfaction disorders: retrospective study.

Area of Science:

• Otolaryngology
• Olfactory dysfunction research
• Human sensory perception

Background:

• Smell is a crucial yet poorly understood human sense.
• Physician awareness of smell disorders impacts diagnosis and treatment.
• Olfactory dysfunction significantly affects patients' quality of life.

Purpose of the Study:

• To characterize patients with smell disturbances.
• To evaluate the management and treatment of olfactory disorders.
• To describe the experience with hyposmia and anosmia patients.

Main Methods:

• Retrospective cross-sectional cohort study.
• Analysis of 38 patients with olfactory complaints (hyposmia/anosmia) from 2005-2011.
• Assessment of treatment responses to topical steroids and alpha-lipoic acid.

Main Results:

• Hyposmia affected 68.4% and anosmia 31.5% of patients, with a mean duration of 30.8 months.
• Common causes included idiopathic (31.5%), rhinitis (28.9%), and chronic rhinosinusitis with polyps (10.5%).
• Variable treatment responses were observed for topical steroids and alpha-lipoic acid.

Conclusions:

• Disorders of smell warrant greater attention in otolaryngology practice.
• The broad differential diagnosis and impact on quality of life underscore the importance of olfactory dysfunction.
• Improved management strategies are needed for patients with smell impairments.
