Paradoxical vocal fold motion: respiratory retraining to manage long-term symptoms.

Paradoxical vocal fold motion (PVFM) is a laryngeal disorder characterized by abnormal adduction of the vocal folds during respiration. It is caused by a multitude of etiologies and their interactions. In the current study, a 24-year-old female patient with a 12-year complaint of shortness of breath was diagnosed with paradoxical vocal fold motion following nasal endoscopy, spirometry testing and detailed case history analysis. She had no history or indication of laryngopharyngeal reflux or chronic cough. She performed respiratory retraining exercises three to four times daily for a period of four weeks, and continued daily exercises for two additional months as needed. After four weeks of treatment, abnormal vocal fold adduction continued to be seen on endoscopy and the patient was mildly symptomatic. One month post-treatment, there was no abnormal vocal fold adduction and the patient reported rare shortness of breath. At three months post-treatment, there was no abnormal vocal fold adduction and the patient no longer reported shortness of breath. She reported normal breathing with no symptoms one year later. The results suggest that non-pulmonary related shortness of breath treated with respiratory retraining can effectively eliminate dyspnea in patients with long term breathing difficulties caused by paradoxical vocal fold motion. Resolution may require treatment over an extended period of time.

O movimento paradoxal de pregas vocais (MPPV) é um distúrbio caracterizado por adução anormal das pregas vocais durante a respiração. Esse distúrbio é causado por uma série de causas e por suas interações. No presente estudo, uma paciente de 24 anos, do sexo feminino, com queixa de falta de ar há 12 anos teve o diagnóstico de movimento paradoxal de pregas vocais, a partir de dados de análise laríngea por nasoendoscopia, espirometria e avaliação clínica. A paciente não tinha histórico nem sinais de refluxo laringo-faríngico ou tosse crônica. A paciente foi submetida à reeducação respiratória, com treinamento de exercícios realizados de 3 a 4 vezes ao dia, por um período de quatro semanas, seguindo com um regime de exercícios diários por mais dois meses. Após quatro semanas de tratamento, a nasoendoscopia continuou indicando adução anormal das pregas vocais, porém em grau leve. Depois de um mês de tratamento, a movimentação das pregas vocais regularizou-se e a paciente referia frequência reduzida dos episódios de falta de ar. No acompanhamento de três meses após o tratamento, não foi observada alteração de adução de pregas vocais e nem referência à queixa de falta de ar. Somente no controle após um ano, a paciente mostrou-se livre de sintomas laríngeos e alteração respiratória. Os resultados sugerem que falta de ar sem alteração pulmonar, tratada por meio de reeducação respiratória fonoaudiológica, pode ser efetiva na eliminação da dispneia em pacientes com história crônica de dificuldades respiratórias causadas por movimento paradoxal de pregas vocais. A resolução do problema pode necessitar um tratamento prolongado.

Respiratory retraining therapy in long-term treatment of paradoxical vocal fold dysfunction.

OBJECTIVES: Paradoxical vocal fold dysfunction (PVFD) is a disorder in the larynx featuring involuntary adduction of the vocal folds during the inspiratory phase of breathing. The symptoms include acute episodes of dyspnea and bouts of coughing. To date, there is no universally acknowledged treatment for PVFD, though respiratory retraining therapy is the treatment of choice. AIMS: The purpose of this work was to evaluate the results of long-term respiratory retraining therapy in cases of PVFD. PATIENTS AND METHODS: We treated 20 patients with PVFD for 2 years: 10 subjects were submitted to a cycle of respiratory retraining therapy every 12 months (receiving a total of 3 cycles) while 10 were given a cycle every 3 months (for a total of 9 cycles) no matter what their clinical conditions were. RESULTS: The results show that long-term respiratory retraining is particularly efficacious if the cycles of treatment are repeated, no matter what clinical conditions are present. In fact, when only one cycle of retraining treatment is given a year, there is initial improvement followed by progressive worsening. CONCLUSIONS: Long-term respiratory rehabilitation is effective, especially if the treatment is given at least once every 3 months.

[Effects on function rehabilitation of vocal cord after vocal cord polyps surgery treated with acupuncture at Sheng's four points of throat].

OBJECTIVE: To observe the effects on function rehabilitation of vocal cord after vocal cord polyps surgery treated with acupuncture at Sheng's Four Points of Throat. METHODS: Sixty cases were randomly divided into a combined therapy group of Four Points of Throat and medication (group 1, 30 cases) and a medication group (group 2, 30 cases). In group 1 Four Points of Throat were punctured and routine medication was applied; in group 2, only routine medication was applied. The scores of symptom-sign and status of voice were observed and analyzed before and after treatment in two groups. RESULTS: At 4th day after the surgery, the improvement of the symptom-sign scores in group 1 was more significant than that in group 2 (P < 0.05); and the voice analysis status in group 1 was superior to that in group 2 (all P < 0.05). The total effective rate was 83.3% (25/30) in group 1, which was superior to that of 60.0% (18/30) in group 2 (P < 0.05). CONCLUSION: The effect on function rehabilitation of vocal cord after vocal cord polyps surgery treated with the combined therapy group of Four Points of Throat and routine medication is favorable, superior to that with routine medication therapy.

[The "intra-cordal polyp": a clinical alternative to recognize?]. / Le polype "intra-cordal" : une variante clinique à reconnaitre?

UNLABELLED: The vocal cord polyp is an inflammatory false tumour of the larynx. It is characterized mainly by the specific existence of fibrinous exsudats organized in loose network or mounds, surrounded by newly formed vascular slits. The epithelium covering the polyp is usually more or less impaired. CLINICAL CASES: The authors report two adult patients among whom the initial presentation in video-stroboscopy was that of an intracordal lesion of a cystic type, however; with unusual characteristics (purplish color, angiomatous aspect). The surgery consisted of a cordotomy, the surface epithelium appearing normal. After dissection, the two lesions seemed to be presenting the typical aspect of fibrinoïd mound of a polyp, observation confirmed by the anatomo-pathological study. In these cases, the resection was finally carried out with no mucous loss. CONCLUSION: The particular etiopathogeny of these lesions is been discussed. The treatment, medical and of rehabilitation could achieve a partial recovery. In the event of surgery, an access to the lesion through a cordotomy and not directly by removal with microcissors is advised.
