Laryngeal fibroma
Laryngeal fibroma is a benign tumor of the larynx originating from connective tissue, composed of fibroblasts and fibrous bundles. The symptoms of laryngeal fibroma are related to the size and location of the tumor. Usually, there are no specific symptoms, but some patients may experience hoarseness, respiratory obstruction, and other symptoms.
View detailsLaryngeal mucocele
Laryngeal mucocele is a cyst formed by the retention of mucus due to obstruction of the mucous gland duct, often occurring on the lingual surface of the epiglottis. The main symptoms of this condition include a sensation of throat obstruction, sore throat, hoarseness, and cough.
View detailsLaryngeal obstruction
Laryngeal obstruction refers to the narrowing or complete blockage of the larynx due to lesions in the larynx and its adjacent tissues, leading to dyspnea. The main symptom of this disease is dyspnea, accompanied by inspiratory stridor and hoarseness.
Caseous rhinitis
Caseous rhinitis refers to a disease in which nasal secretions accumulate in the nasal cavity or paranasal sinuses, forming caseous masses and causing inflammation of the surrounding tissues. The main manifestations of this disease include nasal obstruction, purulent rhinorrhea with a foul odor, and may be accompanied by symptoms such as hyposmia, headache, and nasal deformity.

Functional hearing loss refers to a pseudo-auditory disorder in which patients have no organic lesions of the auditory system. It is a non-organic hearing loss, also known as psychogenic hearing loss or hysterical hearing loss. Some patients may have mild organic disorders, but the auditory impairment they exhibit exceeds their actual hearing.

Ceruminous adenoma is a rare clinical condition, referring to a benign tumor that originates in the cartilaginous part of the external auditory canal due to ceruminous gland hyperplasia. Recurrent cases are prone to malignant transformation. In its early stages, this disease may be asymptomatic. As the tumor gradually enlarges, it can lead to external auditory canal stenosis, obstruction, ear stuffiness, and hearing loss.
View detailsMalignant otitis externa
Malignant otitis externa, also known as necrotizing otitis externa, is an invasive infection caused by bacterial infection, primarily Pseudomonas aeruginosa, of the external auditory canal, with the infection spreading to the adjacent temporal bone marrow and brain tissue. If the temporal bone or skull base is involved, it is called osteomyelitis of the skull base. The main symptoms include persistent severe ear pain at night and discharge from the external auditory canal.
View detailsSubperiosteal abscess behind the ear
When acute exacerbations of middle ear cholesteatoma, chronic suppurative otitis media with mastoiditis, or acute otitis media with mastoiditis occur, pus accumulated in the mastoid cavity flows into the subperiosteal space behind the ear through the destroyed lateral cortical bone of the mastoid, forming a postauricular subperiosteal abscess. It is one of the common complications of otitis media. This condition is more common in infants, young children, and adolescents, with a higher incidence in males. The main symptoms include pain in and behind the ear accompanied by significant tenderness, and pus in the external auditory canal. Further progression of the abscess can lead to ipsilateral headache and fever.
View detailsSuppurative perichondritis of auricle
Perichondritis of the auricle is an infection with pus formation between the cartilage and perichondrium, often occurring after trauma to the auricular cartilage. The main symptoms include severe ear pain, redness, swelling, tenderness to the touch, and a fluctuating sensation upon palpation if an abscess forms. The abscess may even rupture. Severe cartilage destruction in later stages can lead to ear deformity.
