Introduction
In recent years there has been a growing increase in studies of conversion disorders, such interest has been provided by developments in neuroscience, especially in jobs involving brain imaging.[1]
The conversion disorders occur when there is a somatic, or psychological or psychic mechanism is expressed in the form of physical symptoms,[2] among which the bodies of the larynx may be affected.
The larynx is a cartilaginous structure with muscle specific function of producing sound in phonation, respiration and sphincter function. Being a sensible structure, the larynx becomes more vulnerable to various diseases, which worsens over the face of risk factors as smoking and alcohol consumption.[3]
Generally, the initial signs of a throat problem arise in the form of a voice disorder. Multifactorial origin dysphonia presents itself as any changes in voice due to a functional disorder and / or dysfunction of the vocal tract, being the most common form of vocal disorders. Overuse and inappropriate voice is an important example of a cause of dysphonia.[3] [4]
The psycho-emotional disorders can trigger the onset of psychogenic dysphonia related to conversion, the frame being the most common conversion aphonia, defined as the total loss of voice, a disorder that often affects the female gender.[5] [6] [7]
The human voice is unique and allows the individual to communicate with their peers, express thoughts and emotions.[3] Sometimes, psychiatric symptoms often manifest themselves on the vocal tract.[7]
This paper introduces the presentation of a case, its relevance lies in the fact that this form is unusual in the otorhinolaryngology, possibly by the rarity of its occurrence.
In this report the authors describe a case of aphonia case of conversion seen at Hospital das Clinicas, Federal University of Goiás, in Goiânia.

Case Report
VCG patient, 32 years old, female, public employee, postgraduate student, single, born in Goiânia (GO) sought the emergency department of Otorhinolaryngology, Hospital das Clinicas, Federal University of Goias HC / UFG in June 2006 with the following clinical features: aphonia two days ago, no other ENT symptoms apparent.
Said that in the last six months two episodes of aphonia, looking for a health unit. She was seen by an ENT, who through indirect laryngoscopy showed a slight edema between the arytenoid cartilage, suggestive of laryngopharyngeal reflux. At the time it was prescribed omeprazole 20 mg 12/12h, with clinical improvement of the situation after three / four weeks. He reported further that the vocal came after weeks of stressful and exhausting work, followed by evening classes. It states that in the days before the riots showed no signs or symptoms different, just tired and woke at dawn voiceless.
At evaluation, the patient was in good general condition, afebrile, without signs or symptoms of rhinorrhea and nasal itching. Denies alcoholism, smoking, drug use and abuse of voice.
In the otorhinolaryngological oropharyngoscopy, rinofaringoscopia anterior and otoscopy showed no changes.
Based on the clinical laboratory tests were requested, the results were normal. The procedure of laryngoscopy revealed no organic lesions in the laryngeal structures and / or extralaryngeal ([Figure 1]).

Diagnosed with psychogenic aphonia, was recommended to abundant water intake, along with voice therapy. The patient was referred to the audiology clinic of the hospital.
Four days after the initial consultation, the patient showed significant improvement in her voice and was instructed to return to the otorhinolaryngology after 30 days. After this period, he returned without signs of aphonia. The patient was discharged and held follow-up speech therapy.

Discussion
The literature is vast when it comes to vocal disorders, however, the limitation of this study is evidenced by the scarcity of studies that specifically address the conversion aphonia, and such data provide support for further studies on the topic.
Experts believe that the persistent hoarseness, coughing, sore throat, pain and difficulty swallowing, difficulty breathing, vocal fatigue and voice loss may be indicative of lesions in the larynx.[3] In our case, the examination of laryngoscopy did not visualize changes in the level of the larynx, vocal cords or structures proximal to justify the voice disorder.
As suggested in the literature, the diagnosis of aphonia is basically clinical, since there are no lesions in the organs of the larynx or vocal folds.[8] In the case described the laryngeal structures were normal, without lesions.
The case reported it is a female patient. These findings are similar to those described in the literature, where the disease predominantly affects individuals of this genus.[5] [6] [7] [9]
Studies show that the presence of gastroesophageal reflux can lead to laryngeal disorders, vocal disorders and consequently[10]. Although in early episodes have made use of medications for this condition, the vocal symptoms of the patient remained for weeks
Surveys show the anxiety, depression, interpersonal conflicts, difficulties in expressing feelings or opinions of aphonia as etiological factors.[5] [6] [7] [9] [11] Contradicting these data, the case presented the patient denies anxiety, depression or some type of trauma, only mentions the daily stress. This being possible triggering factor of aphonia.
Medical management was based on the vocal rehabilitation and increased fluid intake, resulting in significant improvement of the framework. These findings are similar to several studies that indicate therapies vocal determinants for the prompt recovery of patients.[8] [12] [13]
Studies describe cases in which the voice disorder remains for weeks,[9] [14] in the case presented in only four days the patient had his vocal standard. Due to the rapid improvement of symptoms, the patient was not referred to the psychotherapeutic treatment, as suggested by some studies.[6] [8]
While advances are evident diagnosis still represents a challenge,[1] however, the psychological factor plays an important role and should be considered in the diagnosis and the therapeutic process of patients with vocal disorders.[11] The absence of vocal fold lesions, it was considered agitation or daily stress reported by the patient as a possible trigger factor for the inconvenience experienced by the same voice.
Thus it is important to the differential diagnosis aphonia, since psycho-emotional aspects involving the individual may be somatized for laryngeal structures, and all the emotional charge conveyed to the vocal tract, causing the emergence of vocal changes or disturbances.[14]

Final Comments
The psychological aspects involving patients should be considered in any trouble, since they may cause or modify symptoms and compromise the prognosis.
The medical history preceding the emergence of a vocal to be raised by experts, enabling appropriate action, considering that reflects the voice and transmits a person's personality.
