Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Reconstruction of defect following resection of tongue for malignancy with innervated vastus laterals and anterolateral thigh flap. The steps of this surgery are harvesting of the soft tissue flap and muscle with the innervation intact from the thigh, as routinely done for microvascular reconstruction of he tongue. Microvascular anastomosis will performed as per standard technique with 8-0 nylon. Surgery will be performed by Jonathan Clark/James Wykes. The duration of surgery will be on average 8-10 hours

Outcomes
Primary outcome [1] 321887 0
Assessment of the impact of innervated free flap reconstruction of large tongue defects after subtotal/total glossectomy on swallowing function (composite outcome)

The swallowing assessment is through videofluouroscopy, and functional endoscopic evaluation of swallowing

The speech assessment is through speech and intelligibility assessment (sentences from Frenchay Articulation Assessment, Rainbow Passage and Conversational Speech), intelligibility and percentage of consonants correct and subjective intelligibility by listeners blinded to patient characteristics, and speech handicap index (SHI)

Summary
Brief summary
The purpose of this study is to trial a new method for rebuilding the tongue after cancer surgery

Who is it for?
You may be eligible for this study if you are aged 18 or over and have tongue cancer which requires at least half the tongue to be removed.

Study details
All participants in the study will undergo a reconstructive surgery where a piece of thigh muscle will be used to rebuild part of the tongue. This procedure takes place general anaesthesia during the same surgical procedure where the excision of the tongue cancer takes place, and the entire proceduretakes approximately 8-10 hours. As part of the study, all participants will have post-op assessments of tongue function and answer some questionnaires.

It is hoped this study will help us better understand and standardize tongue reconstruction to improve speech and swallowing outcomes.
