About The Test
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.
What is X-Ray Nasopharynx Lateral View?
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)
List of Parameters
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
Why This Test
- Evaluate adenoid hypertrophy
- Assess chronic nasal obstruction
- Investigate suspected nasopharyngeal mass
- Pre-operative airway mapping for ENT surgeons
- Monitor post-treatment shrinkage
When to Take Test
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.
Benefits
Benefits of Taking the Foot AP & Oblique X-Ray Scan
- 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
Illnesses Diagnosed with Foot AP & Oblique X-Ray Scan
- Adenoid enlargement
- Nasopharyngeal cysts
- Antro-choanal polyps
- Thornwaldt bursitis
- Early nasopharyngeal carcinoma (large masses)
- Retained foreign body
Preparing for test
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
Pre-requisites
- Doctor’s prescription stating clinical indication
- Valid ID for registration
- For children < 5 years, mild sedation scheduling possible if excessive movement expected
Best Time to Take the X-Ray Nasopharynx Lateral View
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.
Eligibility
- Age: Neonates to geriatrics
- Weight: Up to 150 kg (digital table limit)
- Pregnancy: Generally avoided except when benefits outweigh risks; inform technician if pregnant.
Procedure for Taking an X-Ray Nasopharynx Lateral View
- Registration & consent
- Metallic object removal
- Position standing or seated, left side closest to detector
- Chin slightly raised, shoulders relaxed
- Hold breath for 1 second while tube fires
- Image appears on radiologist console; repeat if motion artifact noted
- Verify identification markers and dispatch to PACS
Caution Before Taking the Test
- Pregnant or potentially pregnant patients must declare; lead apron shielding will be applied.
- Patients with cervical spine injury require supine modification—inform technician.
Test Results
Interpretation of Results
| Finding/Observation | Description | General Interpretation/Significance |
|---|---|---|
| Normal scan | No abnormalities detected; adenoids occupy ≤ 60% of nasopharyngeal depth; airway lumen >6 mm wide | Healthy status; no further action required unless symptoms persist |
| Adenoid hypertrophy | Adenoid-to-nasopharynx (A/N) ratio >0.8; narrowed airway | Suggests airway obstruction; may cause snoring, sleep apnea, or mouth-breathing; ENT referral advised |
| Chronic nasal obstruction | Diffuse soft-tissue thickening, no discrete mass | May indicate chronic inflammation or infection; clinical correlation needed |
| Retained foreign body | Unusual radio-opaque object in nasopharynx | Requires urgent removal; risk of aspiration or infection |
| Calcified lymph nodes | Small, dense, rounded shadows near cervical vertebrae | May indicate old infection; usually benign but requires monitoring |
Risks & Limitations
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.
Types of X-Ray Nasopharynx Lateral View
- Conventional film – archived hard copy (rare today).
- Digital radiography – instant image enhancement; used at Cadabams Diagnostics.
- Fluoroscopy-guided – dynamic study, reserved for complex swallowing evaluations.
FAQs
