Hoarseness (Dysphonia): Diagnostic Tests

Obligatory medical device diagnostics.

  • Laryngoscopy (laryngoscopy).

Optional medical device diagnostics – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.

  • Laryngostroboscopy (laryngeal stroboscopy) – assessment of vocal fold function during phonation: regular stroboscopic examinations allow early detection of infiltrative vocal fold processes. Mucosal changes that infiltrate the vocal fold muscles lead to a stroboscopic (phonatory) arrest. If this stagnation persists for 2-3 weeks, the indication for microlaryngoscopic trial excision is given.
  • Sonography (ultrasound examination) of the neck – if lymoh node involvement or tumors are suspected.
  • Computed tomography (CT) of the neck – if tumors are suspected (note: unlike stroboscopy, the value of imaging techniques in early stages of laryngeal carcinoma (cancer of the larynx) is low).
  • If malignancy is suspected – biopsy (tissue sampling) to examine for cell changes.
