Infantile Osteomyelitis
- Osteomyelitis Maxillaries Neonatarum, Maxillitis of infancy
- Osteomyelitis in the jaws of new born infants occurs almost exclusively in maxilla.
Etiology
- Trauma – through break in mucosa cause during delivery.
- Infection of maxillary sinus
- Paunz & Ramon et al believe that disease caused through infection from the nose.
- Hematogenous spread through streptococci & pneumococci
Clinical features
- Fever, anorexia & intestinal disturbances.
- swelling or redness below the inner canthus of the eye in lacrimal region.
- Followed by marked edema of the eyelids on the affected side.
- Next, alveolus & palate in region of first deciduous molar become swollen.
- Pus discharge from affected sites
D/D for Infantile Osteomyelitis
- Dacrocystitis neonatarum
- Orbital cellulitis
- Ophthalmia neonatarum
- Infantile cortical hyperostosis
TREATMENT
- Intravenous antibiotics, preferably penicillin.
- Culture & sensitivity testing
- Incision & drainage of fluctuant areas
- Sequestrectomy
- Supportive therapy
Nasopalatine cyst
Radiology
The nasopalatine cyst appears as a well-defined, round radiolucency in the midline of the anterior maxilla . Sometimes it appears to be 'heart-shaped' because of super-imposition of the anterior nasal spine.
Radiological assessment should include examination of the lamina dura of the central incisors (to exclude a radicular cyst) and assessment of size (the nasopalatine foramen may reach a width of as much as 10 mm).
Pathology
The cyst is lined by a layer of pseudostratified ciliated columnar epithelium and/or stratified squamous epithelium. The capsule of the cyst is fibrous and may include the incisive canal neurovascular bundle.
Nasolabial cyst
Radiology
'Bowing' inwards of the anterolateral margin of the nasal cavity has been recorded
Pathology
The nasolabial cyst is lined by non-ciliated pseudostratified columnar epithelium, which is often rich in mucous cells.
