Conservative Treatment In many cases, nodules can be resolved without surgery through: Vocal rehabilitation with a speech therapist Vocal technique correction with a specialized coach Vocal hygiene education (hydration, rest, environment) Treatment of contributing factors (reflux, allergies) Surgical Treatment When conservative measures are insufficient: Microlaryngoscopy with precise nodule excision Pre-operative vocal rehabilitation (essential preparation) Post-operative silence period (typically 1-2 weeks) Post-operative vocal rehabilitation (critical for preventing recurrence) THE CALYP APPROACH Integrated Vocal Rehabilitation A unique multidisciplinary protocol At CALYP, vocal nodule treatment follows a comprehensive protocol that integrates medical expertise with vocal coaching: Speech therapists address spoken voice rehabilitation, while vocal coaches trained in the Adeline Toniutti method correct the singing technique issues that caused the pathology
