PNS Water view is a specialized radiographic (Waters') projection of the paranasal sinuses that best visualizes maxillary sinuses and orbital rims. Patient extends the neck so the orbitomeatal line forms about a 37° angle to the image plate; the beam projects through the occipitomental plane. It's used to detect sinusitis, air–fluid levels, maxillary fractures and mucosal thickening.

A CT PNS (CT scan of the paranasal sinuses) assesses sinus anatomy and pathology. It detects sinusitis, mucosal thickening, polyps, cysts, tumors, bone fractures and complications such as orbital or intracranial spread. It guides diagnosis for recurrent or chronic sinus symptoms, nasal obstruction, pre-operative planning for endoscopic sinus surgery, and evaluation after trauma or when symptoms don’t respond to treatment.

The Waters (occipitomental) radiographic view primarily demonstrates the maxillary sinuses. It provides excellent visualization of the maxillary antra, orbital floors, infraorbital rims, and anterior ethmoid air cells. It is commonly used to assess maxillary sinusitis, orbital floor fractures, and sinus opacification. Posterior ethmoid and sphenoid sinuses are less well visualized on this projection.

Do you mean "OM" as otitis media (middle ear infection), oral mucositis, osteomyelitis, or something else? Tell me which one and I’ll provide a 50–75 word summary.

CT PNS (paranasal sinuses) costs vary by country, facility and insurance. In India private centers often charge about ₹1,200–6,000; in the UK it’s free on the NHS or roughly £100–£400 privately; in the US billed charges commonly range $300–$3,000, with insured out‑of‑pocket costs often $50–$500. Confirm price and contrast use with your provider.

The Waters (occipitomental) view is an X‑ray projection used to evaluate the facial skeleton, especially maxillary sinuses, orbital floors, and zygomatic arches. It helps detect sinus disease, maxillary sinus and orbital blowout fractures, displaced zygomatic fractures, and foreign bodies. It’s commonly performed in facial trauma and suspected sinus pathology to complement other radiographs or CT when needed.
