Brief summary
The aim of the study is to show that the innovative, dynamic palatal reconstruction technique (free radial flap plasty in combination with displacement of the digastric muscle) leads to a good functional outcome in terms of speech and swallowing in the context of the current literature.
Detailed description
Tumors in the throat and pharynx are common and often lead to impaired swallowing and phonation after surgical tumor resection. The posterior part of the digastric muscle is responsible for sealing during the pharyngeal swallowing phase, among other things. By relocating the digastric muscle, a defect in the area of the soft palate can now be reconstructed with a muscle whose physiological function is already integrated into the complex process of the swallowing act and thus leads to a better seal. This new, previously undescribed reconstruction option has been used on various patients at the University Hospital with good functional results. This study is to describe the new dynamic technique for soft palate reconstruction and to analyze the associated functional and surgical outcomes including postoperative complications, speech and swallowing function. The resulting values will be compared with the existing literature. The aim is to investigate whether the functional outcome in terms of phonation and swallowing can be improved by this technique.
