Nasopharynx Lateral View X-Ray Scan

A clear side-profile picture of the nasopharynx can reveal hidden swelling, abnormal growths or blocked airways before symptoms worsen. Cadabams Diagnostics offers the XR NASOPHARYNX LATERAL VIEW as a 10-minute, walk-in procedure with same-day digital reports.

The X-Ray nasopharynx lateral view is a focused, side-angle radiograph that captures the space behind the nasal cavity and above the soft palate. The beam enters from one side of the head and exits the other, producing a two-dimensional image that highlights:

• Adenoid size
• Soft-tissue thickness
• Air passage width
• Bony landmarks (sphenoid, cervical vertebrae)

1. Conventional film – archived hard copy (rare today).
2. Digital radiography – instant image enhancement; used at Cadabams Diagnostics.
3. Fluoroscopy-guided – dynamic study, reserved for complex swallowing evaluations.

Radiologists measure:

• Adenoid-to-nasopharynx (A/N) ratio
• Soft-tissue thickness at C1–C3
• Airway lumen width
• Cervical spine alignment
• Presence of calcified lymph nodes

• Evaluate adenoid hypertrophy
• Assess chronic nasal obstruction
• Investigate suspected nasopharyngeal mass
• Pre-operative airway mapping for ENT surgeons
• Monitor post-treatment shrinkage

Doctors usually request the test when patients report:

• Mouth-breathing in children
• Snoring or sleep-apnea suspicion
• Persistent nasal blockage
• Recurrent ear infections
• Speech changes (hyponasal voice) Both adults and children can undergo the scan; no age restrictions apply at Cadabams Diagnostics.

• Quick: 5–10 minutes door-to-door
• Painless: no contrast or needles
• Economical: fraction of CT/MRI cost
• Child-friendly: open-bay unit allows parent accompaniment
• Digital copies: share instantly with referring doctor

• Adenoid enlargement
• Nasopharyngeal cysts
• Antro-choanal polyps
• Thornwaldt bursitis
• Early nasopharyngeal carcinoma (large masses)
• Retained foreign body

Do

• Remove earrings, hairpins, dentures
• Wear a front-opening gown
• Bring previous scans for comparison

Don’t

• Apply facial metallic cream on the day
• Panic about radiation;剂量 is negligible

• Doctor’s prescription stating clinical indication
• Valid ID for registration
• For children < 5 years, mild sedation scheduling possible if excessive movement expected

Any weekday morning helps avoid crowds; however, Cadabams Diagnostics offers 12-hour operation, so you may book a slot post-school or post-work. Fasting is unnecessary.

• Age: Neonates to geriatrics
• Weight: Up to 150 kg (digital table limit)
• Pregnancy: Generally avoided except when benefits outweigh risks; inform technician if pregnant.

1. Registration & consent
2. Metallic object removal
3. Position standing or seated, left side closest to detector
4. Chin slightly raised, shoulders relaxed
5. Hold breath for 1 second while tube fires
6. Image appears on radiologist console; repeat if motion artifact noted
7. Verify identification markers and dispatch to PACS

• Pregnant or potentially pregnant patients must declare; lead apron shielding will be applied.
• Patients with cervical spine injury require supine modification—inform technician.

Risks

• Minimal radiation (≈ 0.02 mSv, less than a week of natural background).

Limitations

• Only shows bone and soft-tissue silhouettes; cannot separate subtle lymphoid detail.
• Overlapping structures may hide tiny masses—cross-sectional imaging (CT/MRI) may be needed if clinical suspicion remains high.
