The upper respiratory tract, serving as the gateway of our respiratory system, connects the external environment with the body's interior. It performs crucial functions of filtering, warming, and humidifying inhaled air. When problems arise in this area, various respiratory diseases can emerge.

So, do you know which diseases fall under the category of upper respiratory tract conditions?

Upper respiratory tract diseases generally refer to conditions affecting the nasal cavity, pharynx (including nasopharynx, oropharynx, and laryngopharynx), larynx, and other related areas.

These diseases encompass a wide variety, including both acute or chronic inflammations caused by infections, as well as tumors induced by genetic factors, environmental influences, or poor lifestyle habits. Even trauma can lead to damage in this region.

1. Inflammatory Diseases

1. Common Cold

This is one of the most well-known upper respiratory tract inflammations, usually caused by viruses (such as rhinovirus, coronavirus), manifesting as symptoms like cough, fever, runny nose, and sore throat.

Although the common cold is mostly a self-limiting disease, proper care and appropriate treatment can accelerate the recovery process.

2. Rhinitis and Sinusitis

Rhinitis refers to inflammation of the nasal mucosa, while sinusitis involves inflammation of the sinuses (air-filled cavities in the skull). Both conditions can cause symptoms such as nasal congestion, runny nose, headache, and reduced sense of smell, seriously affecting the quality of life when severe.

3. Pharyngitis, Epiglottitis, and Laryngopharyngitis

These inflammations affect different parts of the pharynx respectively, with shared symptoms including throat pain, dysphagia, and hoarseness. Epiglottitis requires urgent medical attention as it may rapidly progress to cause breathing difficulties.

II. Neoplastic Diseases

1. Nasopharyngeal Tumors

Including nasopharyngeal carcinoma and others, which may initially present with no obvious symptoms. As the disease progresses, symptoms such as nasal congestion, bloody nasal discharge, tinnitus, and hearing loss may occur. Early detection and treatment are crucial.

2. Throat Tumors

Laryngeal cancer is representative of such tumors, with common symptoms including hoarseness, persistent sore throat, difficulty swallowing, and neck masses. Smoking and alcohol consumption are major risk factors.

3. Trauma

In addition to infections and tumors, trauma is also a significant cause of upper respiratory tract diseases that should not be overlooked. Accidents such as car crashes or falls may lead to nasal bone fractures or airway injuries.

In conclusion, when facing any symptoms of respiratory discomfort, seek medical attention promptly and follow the advice of healthcare professionals.
