Taste disorders are rare compared to olfactory problems, and so the workup and understanding of taste disorders is limited. In this article, we try to update knowledge about human taste disorders with a special focus on taste disorders occurring after ENT surgery.

It is not uncommon for individuals receiving radiotherapy for head and cancers to experience dry mouth sensation (xerostomia), salivary hypofunction (hyposalivation) and taste changes. The present study aimed to evaluate the short-term effectiveness of biweekly photobiomodulation therapy (PBMT) in managing these radiotherapy-induced adverse effects and its impact on oral health-related quality of life. Ten patients who developed xerostomia and hyposalivation secondary to radiotherapy for head and neck cancer were included.

Eating behaviours are influenced by the integration of gustatory, olfactory and somatosensory signals, which all contribute to the perception of flavour. Although extensive research has explored the neural correlates of taste in the gustatory cortex (GC), less is known about its role in encoding thermal information. This study investigates the encoding of oral thermal and chemosensory signals by GC neurons compared to the oral somatosensory cortex.

Purpose Of Review: Parosmia is a qualitative olfactory disorder in which there is a mismatch between the memory of an odor and the actual experience triggered by an odor. There has been a surge in parosmia-related publications since the COVID-19 pandemic. This review summarizes the latest clinical findings, theories on pathophysiology and potential treatment options.

Background: Individuals with avoidant/restrictive food intake disorder (ARFID) self-report heightened sensitivity to taste and smell, but neither phenomenon has been systematically explored in the laboratory. We hypothesized that, compared to healthy controls (HC, n = 34), children, adolescents, and adults with full/subthreshold ARFID (n = 100; ages 9 to 23 years) would self-report heightened response to taste/smell stimuli and exhibit stronger bitter taste perception and heightened smell perception in performance-based tasks, and these differences would be especially prominent in those with the ARFID-sensory sensitivity presentation.
Method: We measured self-reported sensitivity to taste/smell with the adolescent/adult sensory profile (AASP).

Background: Dysgeusia is a distortion of the sense of taste whose prevalence and relationship with nutritional status in Metabolic dysfunction-associated Steatotic Liver Disease (MASLD)-related advanced chronic liver disease (ACLD) have never been systematically explored.
Methods: 200 MASLD patients [60 ≤ F3 fibrosis, 70 compensated ACLD (cACLD), and 70 decompensated (dACLD)] were enrolled. At baseline, the Child-Pugh (CP) score was determined.
