BACKGROUND: Surgery of the soft palate in patients with oropharyngeal cancer can result in functional deficiencies of swallowing and speech. Reconstruction of the resected structures can contribute to regaining sufficient functionality after therapy.
OBJECTIVE: The current study used frequency analysis to evaluate the change in speech characteristics after resection and reconstruction of the soft palate during post-therapeutic follow-up.
MATERIALS AND METHODS: In 18 patients with oropharyngeal carcinoma and involvement of the soft palate, resection and reconstruction by free radial forearm graft (FRFG) and adjuvant chemoradiotherapy was conducted. The spoken German numbers "eins", "zwei", "drei", "vier", "fünf" were recorded during follow-up and objectively assessed by frequency analysis. Additionally, food intake status and the necessity of a tracheostomy were evaluated.
RESULTS: The maximum peak frequencies of the numbers analysed increased from 150-300 Hz before up to 1000 Hz after therapy. Two years post therapy, the peak frequencies again declined to levels comparable to those before tumour therapy. One year after therapy, complete oral nutrition was possible in two thirds of patients and the tracheostomy was closed in 80%.
CONCLUSION: Reconstruction of the soft palate by FRFG during the course of oropharyngeal cancer treatment allows function to be regained with respect to speech and swallowing. In the majority of patients, it is possible to reach a level of function comparable to the state before tumour treatment.
