“…The subject of comparison was a 46 year-old female with ICA who volunteered to participate as part of this research. Due to the rarity of congenital aglossia, the prevalence is unknown and the participating subject is one of 12 individuals reported in research literature since 1718 [2]. Her flavor perception was compared to a naïve wine taster with a tongue and professional sommelier.…”

“…The fourth subject with the condition who had reported taste perception is the same subject for the current study. She was found to have best detected salty, sour, sweet, bitter, and umami at 5.8 g/L sodium chloride, 0.66 g/L and 0.066 g/L acetic acid, 171 g/L sucrose, 0.1 g/L and 0.02 g/L anhydrous caffeine, and 0.85 g/L, and 0.085 g/L monosodium glutamate, respectively [2]. This was the first report of umami taste perception in a person with ICA [2].…”

Objective: This study aimed to augment previous research that investigated flavor perception in isolated congenital aglossia by a whole food/beverage approach. Isolated congenital aglossia is the rare condition of absence of a tongue at birth without the presence of other symptoms. Previous studies confirmed taste perception in isolated congenital aglossia using single taste solutions including sour, salty, sweet, bitter, and umami. Methods:The current randomized, double-blinded study age-and sex-matched a naïve wine taster and sommelier to the 46 year-old female with isolated congenital aglossia. A Nose and Palate Survey with 54 variables created based on the Court of Master Sommeliers Deductive Tasting Format was used to evaluate flavor perception. All of the five red wines were tested in triplicate in random order, for a total of 15 separate samples per subject.Results: There was a significant difference in overall nose ratings among the participants F(2,42)=63.461, p<0.001, with post hoc analysis revealing differences in overall nose ratings between the person with isolated congenital aglossia and sommelier (p<0.001), as well as between the naïve wine taster and sommelier (p<0.001). There was a significant difference in overall palate ratings among the participants F(2,42)=48.651, p<0.001, and post hoc analysis revealed differences in overall palate ratings between the person with isolated congenital aglossia and sommelier (p<0.001), as well as between the naïve wine taster and sommelier (p<0.001). There were no significant differences between the person with isolated congenital aglossia and naïve wine taster with a tongue for either overall nose or palate ratings. Conclusion:These results support previous findings that individuals with isolated congenital aglossia can discern various taste and flavor stimuli and suggest that absence of tongue does not greatly affect wine flavor perception among naïve wine tasters.

This article details an account of a young female with congenial aglossia. Because of the low incidence of this anatomical and physiological presentation, this narrative review includes a brief historical review of the disorder and a detailed description of: (1) reports in the literature of congenital hypoglossia and aglossia, (2) characteristics of speech in children with congenital aglossia below the age of 18 years, and (3) the medical history, speech acquisition, and course of intervention of a 5-year-old girl with congenital aglossia currently in speech treatment.

Objective: Antoine de Jussieu, renowned French botanist and physician, laid the groundwork for future research on the topic of congenital aglossia when his study, "Observation About How a Girl Born Without the Tongue Was Able To Perform All Functions That Depend On That Organ," was presented to the 22-member assembly of the Royal Academy of Sciences of Paris on April 22, 1718. This study reviews the literature on de Jussieu's report. Study design:The original report by de Jussieu was read and translated into English, after which 94 studies about congenital aglossia history and botany were selected. Results:Of the 95 studies selected, one refers to de Jussieu's report (the groundwork), Annex I; 85 discuss congenital aglossia; five are about history and four about botany. Of the 85 directly associated with congenital aglossia, 36 do not mention de Jussieu, and 49 cite his observations differently. Conclusion:Because of the 1718 report, de Jussieu became a major figure in the history of congenital aglossia and the author most often quoted in studies about it. However, there were historical facts that needed to be clarified. Some of the issues addressed in this review included the replacement of the letter A with M as the initial of de Jussieu's first name; the omission of the word née in the original title; the replacement of née sans langue with privée de langue in the title; the change of the girl's age from 15 to nine years; the suggestion that the patient had limb defects; the change of year from 1718 to 1717 and 1719; the incorrect spelling of de Jussieu's name and title of his report.

Randomized testing of taste discrimination in a case of congenital aglossia

Abstract: Conclusion:This study has demonstrated the perception of different tastes in a PWCA. This is the first known report of umami being identified as a unique taste in a PWCA. Variations in threshold taste concentrations compared to normal individuals indicate certain gustatory dysfunction.
