Gustatory Function Following Radiotherapy to the Head and Neck

NCT03738657 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 110

No results posted yet for this study

Summary

The aim of this study is to assess the effect of RT or chemo-RT on chemosensory gustatory function in patients with HNC. By using detailed dosimetric data derived from the RT planning system, we will be able to calculate mean radiation doses to important structures including the anterior and posterior tongue, oral cavity, parotid and submandibular salivary glands, and correlate them with both qualitative and quantitative data for dysgeusia.

Conditions

Interventions

OTHER

Olfactory screening

Therefore prior to gustatory testing, patients will be screened and assessed as having either normal or abnormal olfactory function using the Sniffin' Sticks (Burghart; Wedel, Germany). The test consists of 12 odour pens which represent every-day odours (peppermint, fish, coffee, banana, orange, rose, lemon, pineapple, cinnamon, cloves, leather and liquorice). Patients are presented with an odour and select the perceived smell using a multiple-forced-choice method.

OTHER

Quantative Gustatory Testing using Taste Strips

Following screening for olfactory function, whole mouth gustatory function will be assessed using validated taste strips (Burghart; Wedel, Germany). Filter paper test strips are impregnated at one end with 2cm2 of either sweet, sour, salty or bitter taste solutions in four concentrations. In a pseudo-randomised sequence, individual strips will be placed on the tongue and patients will be asked to close their mouth in order to assess whole mouth function. Through a forced-choice procedure patients will be asked to identify the taste stimuli. Scores for individual taste qualities will range from 0-4 and an overall taste score will range from 0-16. Patients will rinse their mouth with tap water prior the application of each taste strip.
