Study Notes
Common Malignant Tumors
- The most common malignant nasal tumor is squamous cell carcinoma.
Olfactory Mucosa Tumors
- Olfactory neuroblastoma arises from the olfactory mucosa and is often found in older male patients.
Neoplasm Type
- Angiofibroma is classified as a benign fibrovascular neoplasm.
Tumors in Adolescents
- Nasopharyngeal angiofibroma is common in adolescent males, typically located in the posterior-lateral nasal wall and nasopharynx.
Regional Tumor Prevalence
- The most common upper respiratory tract tumor in Southeast Asia and East Africa is nasopharyngeal carcinoma.
Benign Yet Aggressive Tumors
- Adenoid cystic carcinoma is histologically benign but exhibits locally aggressive behavior.
Common Cold Etiology
- The most common cause of the common cold is rhinovirus, characterized by symptoms like coryza, sneezing, nasal congestion, and mild sore throat.
Granulomatous Inflammation
- Granulomatosis with polyangiitis involves granulomatous inflammation primarily affecting the nose, nasopharynx, larynx, and trachea.
Immune Reactions
- Allergic rhinitis involves an IgE-mediated immune reaction, leading to increased eosinophils in blood and nasal discharge.
Bacterial Infection Factors
- Environmental factors such as air pollution, smoking, and viral infections can lead to bacterial infections superimposed on acute viral or allergic rhinitis.
Complications of Bacterial Infection
- Common complications of bacterial infection in acute rhinitis include sinusitis, otitis media, and bronchitis.
Endemic Microorganism
- Klebsiella rhinoscleromatis is endemic in Egypt and primarily responsible for causing rhinoscleroma.
Rhinoscleroma Features
- Characteristic features of rhinoscleroma include large granulomatous tumors and fibrosis in the nasal region.
Anterior Nasopharynx Anastomosis
- The anastomosis formed by terminal branches of arteries in the anterior segment of the nasopharynx is known as the Kiesselbach plexus.
Vocal Cord Condition
- Inflammation and edema of the vocal cords, resulting in hoarseness, is referred to as laryngitis.
Epistaxis Causes
- The most common cause of epistaxis (nosebleed) in adolescent males is due to anterior nose trauma or dry air.
Sinusitis Affected Sinus
- The maxillary sinus is typically affected in cases of sinusitis.
Life-Threatening Condition in Children
- Epiglottitis, usually caused by Haemophilus influenzae, can be life-threatening in young children.
