Occipito-mental side projection radiography in childhood maxillary sinusitis

Area of Science:

• Pediatric Radiology
• Otolaryngology
• Medical Imaging

Background:

• Acute maxillary sinusitis is common in children.
• Radiographic imaging plays a role in diagnosis and management.
• Different radiographic projections may offer varying diagnostic value.

Purpose of the Study:

• To compare the diagnostic efficacy of occipito-mental (OM) and occipito-mental side (OMS) projections in childhood acute maxillary sinusitis.
• To evaluate the utility of these projections in assessing retained maxillary secretions and mucosal thickening.
• To determine the optimal projection for acute diagnosis versus treatment follow-up.

Main Methods:

• 152 sinuses in children with acute maxillary sinusitis were examined.
• Both standard OM and OMS radiographic projections were utilized.
• Sinuses were assessed for retained secretions and mucosal thickening in the acute phase and during follow-up.

Main Results:

• The OMS projection demonstrated superiority in detecting retained maxillary secretions in 13% of sinuses during the acute phase.
• This superiority decreased to 1% during the follow-up phase, primarily due to differences in mucosal thickening.
• The clinical significance of 'mucosal thickening' differs between acute and follow-up phases.

Conclusions:

• Single OM projection is often sufficient for clinical evaluation of childhood maxillary sinusitis.
• OMS projection can be a valuable adjunct or alternative to OM in the acute phase for visualizing retained secretions, despite increased radiation.
• In unilateral cases during treatment evaluation, OMS projection can replace the standard OM projection.
