Optional medical device diagnostics – depending on the results of the history, physical examination, and obligatory laboratory parameters – for differential diagnostic clarification.
- Loupe laryngoscopy (reflection of the larynx with a magnifying glass) – to exclude laryngitis or malignant (malignant) process.
- Sonography (ultrasound examination) of the oropharynx (oral part of the pharynx) and oral cavity – e.g., in case of suspicion of neoplasms.
- Computed tomography (CT; sectional imaging procedure (X-ray images from different directions with computer-based evaluation)) of the neck – if neoplasms are suspected.
- Magnetic resonance imaging (MRI; computer-assisted cross-sectional imaging procedure (using magnetic fields, that is, without X-rays)) of the neck – for suspected neoplasms.
