Noma, a severe necrotizing disease, results from bacterial infection and ischemia, causing facial destruction. It primarily affects malnourished children in sub-Saharan Africa, often preceded by oral lesions.
Area of Science:
- Oral and Maxillofacial Surgery
- Infectious Diseases
- Pediatrics
Background:
- Noma (cancrum oris) is a severe necrotizing disease of uncertain cause.
- It involves polybacterial infection and secondary ischemia, leading to facial structure destruction.
- Noma primarily affects malnourished or debilitated children in sub-Saharan Africa, often linked to systemic illnesses.
Purpose of the Study:
- To summarize the etiology, clinical presentation, and epidemiology of noma.
- To highlight the severe functional impairment and disfigurement associated with the disease.
- To discuss the role of pre-existing conditions and oral lesions in noma development.
Main Methods:
- Literature review of noma etiology and clinical characteristics.
- Analysis of epidemiological data concerning noma prevalence.
- Synthesis of information on associated risk factors and preceding conditions.
Main Results:
- Noma is characterized by necrotizing fasciitis, myonecrosis, and osteonecrosis.
- Malnutrition, malaria, measles, tuberculosis, and HIV debilitation are significant risk factors.
- While often preceded by necrotizing stomatitis, noma can rarely occur without prior oral lesions.
Conclusions:
- Noma is a devastating disease requiring prompt recognition and management.
- Understanding its multifactorial etiology is crucial for prevention and treatment strategies.
- Noma is neither recurrent nor transmissible, but its impact on affected individuals is profound.
