Obligatory medical device diagnostics.
- Laryngoscopy (laryngoscopy).
Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and obligatory medical device diagnostics – for differential diagnostic clarification.
- Echolaryngography (ultrasound examination of the larynx including assessment of vocal folds and pocket folds).
- X-ray of the thorax (X-ray thorax/chest), in two planes.
- Computed tomography (CT) of the neck – in unilateral idiopathic recurrent paresis.
- Computed tomography (CT) of the abdomen (abdominal CT) – for further diagnosis.
Further notes
- In a study of 174 patients with idiopathic unilateral recurrent paresis, patients underwent contrast-enhanced computed tomography (CT) from the skull base to the mediastinum. In 5 patients (2, 9 %), CT was able to identify the cause: in 4 cases, a malignant (malignant) tumor and in one case, a benign (benign) tumor was detected.Almost ten times more frequently, incidental findings were detected that were unrelated to the recurrent paresis. In most cases, these were findings in the lungs and thyroid gland. The thyroid finding later turned out to be thyroid carcinoma (thyroid cancer).
