AIM: The aim of this study is to describe the use of Godoy & Godoy Cervical Stimulation Therapy to improve the clinical signs and symptoms of lymphedema after laryngeal cancer treatment. Case report: The case of a 62-year-old patient is reported who made an ultrasound and found a nodule in the larynx and diagnosed laryngeal cancer. The patient was submitted to chemotherapy and radiotherapy. After treatment, the patient complained of neck pain, difficulty in swallowing, decreased saliva production, difficulty in sleeping and hoarseness. The patient was then referred to the Clinica Godoy for treatment of the edema where Cervical Stimulation Therapy as described by Godoy & Godoy was performed. A marked improvement was observed in the first few days with the voice and swallowing of solids returning to normal. CONCLUSION: The Cervical Stimulation Therapy improvement of signs and symptoms of lymphedema resulting from laryngeal cancer treatment.

The Brazilian National Cancer Institute (INCA) estimated that there were 7350 new cases of laryngeal cancer in Brazil in 2016, with an estimated risk of 6.43 cases in every 100,000 men. This type of cancer occurs mostly in over 40-year-old men; the prevalence in women is so low that a statistical estimate is not recommended. In the world, laryngeal cancer is the second most common cause of neoplasia of the respiratory system and the most common type of head and neck cancer. The most recent global estimate is about 129 thousand new cases per year, with a death rate of 70 thousand people annually. Smoking and alcohol are the main risk factors followed by family history, poor diet, unfavorable economic conditions and exposure to Human papillomavirus (HPV) and chemical products among others. The most common symptoms are: persistent infections and hoarseness, dysphagia, pain, dyspnea, halitosis, weight loss and, more rarely, ear ache. When diagnosed in the early stages the prognosis for cure is 80 to 100%. Treatment involves chemotherapy and radiotherapy, with one complication of treatment being the onset of lymphedema. Lymphedema is characterized by an abnormal accumulation of protein-rich fluid and macromolecules in the tissue due to dysfunction of the lymphatic system. Thus an imbalance between the formation of lymph and its absorption occurs . In recent years, a new technique of manual lymphatic drainage called Cervical Stimulation Therapy was developed mainly to treat lymphedema of the head and neck.
