Introduction
In general, laryngoscopy refers to the medical examination of the larynx. Laryngoscopic examination may detect conditions such as vocal cord damage, chronic pharyngitis, vocal polyps, epiglottic cysts, and laryngeal cancer. If you experience any discomfort, it is recommended to seek medical attention immediately and receive appropriate treatment under the guidance of a qualified physician. Additionally, it is important to avoid speaking loudly for prolonged periods or overusing your voice, as well as to reduce habits such as smoking and excessive alcohol consumption, in order to maintain good health.
Generally, laryngoscopy refers to the examination of the larynx. Laryngoscopic examination may detect conditions such as vocal cord damage, chronic pharyngitis, vocal polyps, epiglottic cysts, and laryngeal cancer. If experiencing any discomfort, it is recommended to seek medical attention promptly and undergo appropriate treatment under the guidance of a qualified physician. Detailed explanations are as follows:
1. Vocal Cord Damage
Vocal cord damage may be caused by nerve injury, viral infection, or other factors. Patients may experience symptoms such as difficulty speaking and hoarseness. Laryngoscopy can reveal abnormal vocal cord movement, such as incomplete vocal cord closure or restricted vocal cord abduction.
2. Chronic Pharyngitis
Chronic pharyngitis is a condition characterized by long-term chronic inflammatory irritation of the mucous membrane of the throat. Patients may experience symptoms such as a foreign body sensation, dryness, or a burning feeling in the throat. Laryngoscopic examination may reveal pathological changes such as congestion, thickening of the throat mucosa, and lymphoid follicle hyperplasia.
3. Vocal Polyps
Vocal polyps are benign growths that develop on the edges of the vocal cords, usually caused by long-term improper or excessive voice use. Symptoms may include hoarseness and difficulty speaking. Laryngoscopy can clearly visualize the polyps on the vocal cords.
4. Epiglottic Cyst
An epiglottic cyst is a cyst located beneath the mucosa of the epiglottis, usually caused by chronic inflammatory irritation or obstruction of mucous glands. Patients may experience discomfort or a foreign body sensation in the throat. Laryngoscopy can clearly visualize the cyst on the epiglottis, aiding in diagnosis.
5. Laryngeal Cancer
Laryngeal cancer refers to malignant tumors of the larynx. Patients may experience symptoms such as hoarseness, difficulty breathing, and coughing. Laryngoscopy can detect abnormal mucosal growth, ulcers, or masses in the larynx.
In daily life, it is important to avoid speaking loudly for prolonged periods or overusing the voice, and to reduce unhealthy habits such as smoking and drinking alcohol to maintain overall health.
