Understanding speech changes after oral cancer surgery

Speech Flexibility in Adulthood Following Oral Cancer Treatment: Acoustic and Kinematic Explorations

Observational University Medical Center Groningen · NCT05876247

This study looks at how surgery for oral cancer affects speech and whether different people's reliance on their senses can change how well they adapt their speech over time.

What this trial studies

This observational study aims to investigate the effects of surgical treatment for oral cavity squamous cell carcinoma on speech articulation. Participants will undergo various speech tasks while their articulatory movements are monitored using electromagnetic articulography. The study will focus on how individual differences in sensory reliance may influence the effectiveness of speech compensatory strategies over time. By tracking these changes longitudinally, researchers hope to gain insights into the rehabilitation process for patients post-surgery.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are native Dutch speakers and have a diagnosis of T1 or T2 oral cavity tumors.

Not a fit: Patients with recurrent oral cancer, pre-existing speech disorders, or significant neurological or psychological conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve speech rehabilitation strategies for patients recovering from oral cancer surgery.

How similar studies have performed: While similar studies have explored speech rehabilitation, this specific approach using motion tracking in the context of oral cancer treatment is relatively novel.

Inclusion Criteria:

1. Diagnosed with T1 or T2 tumor in the oral cavity
2. At least 18 years old and able to provide informed consent
