On this day, a father brought his son to the clinic. The son stood in the corner without saying a word, looks twenty years old, height 1.82 meters, physical stature, physical appearance is very enviable, must be the ideal Prince Charming in the dreams of young girls. But his eyebrows contain a wave of sadness and anxiety. What could be wrong with him? In the father’s account, I understand the original cause of the matter: his son Zhang is a fresh graduate of the university, is looking for jobs around. But so far, no organization had hired him. It turns out that he speaks in a high and sharp tone, very much like a woman’s speech, a mouthful of sissy. The first company job interviews, he a mouth to speak, but some people sneer up. When he walked out of the room, he also heard someone laugh that he looked like a eunuch. He was so angry that he did not want to go to the interview, only asked to be contacted by E-mail, or not say a word during the interview. How can this work? Zhang has been to several hospitals to seek treatment for this problem, and has been diagnosed as “male voice female tone”, but the treatment effect is poor. What is a male voice with a female tone? Let’s start with normal human pronunciation. The vocal cords are like strings, it is the human body’s articulator, by the impact of the exhalation of airflow and vibration and sound. The pitch is related to the frequency of vibration of the vocal cords and the length of the vocal cords. Just as you tighten the strings a little, a little shorter, the frequency is fast, the piano pitch will be a little higher; relax the strings, lengthening, the frequency is slow, the pitch is lowered. The principle of the pitch of the vocal cords is similar to that of the strings. When the vocal cords are tense, the frequency is fast and the pitch is high; when the vocal cords are loose, the frequency is slow and the pitch is low. Each person’s vocal folds are different in length, thickness, height, vocal fold closure, vibration, resonance chamber, gender and age; therefore, they produce different tones, so we can distinguish different people according to their voice. Newborns are born with a range of about 6 degrees, and as they grow older, their larynx grows and their range changes. 1 year olds have a range of 8 degrees, and from 5-6 years old until puberty, the larynx changes only slightly. When males enter puberty, under the catalyst of endocrine (mainly pituitary hormones and sex hormones), the larynx grows rapidly due to development, forming the male symbol – laryngeal nodes, laryngeal muscles grow at the same time, and the vocal folds also grow by 1/3, with corresponding changes in thickness, width and quality. As one of the secondary sex characteristics of the voice, the voice from the childhood voice of the sharp and thin to the adult voice of the thick, majestic, deep, in just 5-6 months, the range can be widened to two 8 degrees or wider, while the psychological changes also occur in the larger. The changes in the female adolescent larynx are not as pronounced as those in males, and voice changes are often not easily perceived, gradually changing to adult tones and ranges. Part of the male youth in the period of voice change, due to abnormal hormone levels in the body, thyroid cartilage and vocal folds development imbalance, coupled with psychological adaptation, life is not adjusted, not pay attention to the voice, may change voice abnormalities, the tone of the voice to become more sharp and high, which is the “male voice, female voice”. This is the case of Xiao Zhang. In order to treat the female voice, the doctor should first understand the condition, analyze the cause of the disease with the patient, and analyze the favorable conditions and steps for corrective treatment, and strive to get the cooperation of the patient. Currently, the medical means of treatment include psychotherapy, laryngeal massage, physiotherapy, electro-excitatory therapy, speech training and other conservative treatments. Patients with male and female voices will have different degrees of psychological changes in addition to changes in their voices, and they tend to be mentally stressed, often distressed, worried, bitter and inferior. Psychological treatment is the key to success. Laryngeal massage can improve the intrinsic feeling of the larynx and improve the function of articulation. The specific technique is to place the thumb opposite to the remaining four fingers on both sides of the patient’s thyroid cartilage, and do rotary pressurized massage repeatedly from top to bottom and then from bottom to top, three times a day for 15-20 minutes each time. Electrical excitation therapy is the induction current poles placed on both sides of the thyroid cartilage, the point of sending electricity and make synchronized pronunciation, in order to correct bad vocal habits. Others use the training method of instructing patients to change the vocal control center, etc. These can often achieve the purpose of treating male and female voices. For patients whose conservative treatment is ineffective, thyroid chondroplasty-type III surgery can be performed to relax and shorten the vocal cords, reduce the tension of the vocal cords, and then with pronunciation training, most patients can regain their normal male voice tone. After the thyroid chondroplasty and the postoperative pronunciation training, Xiao Zhang was able to produce a low and loud baritone voice and regained his confidence in life, and started to interview for job opportunities.
