Nasal Endoscopy Findings - Both Sides

Image 1 (First Side - with instrument visible)

• Nasal septum - visible on the medial side, smooth mucosal surface, appears relatively intact
• Lateral nasal wall - visible on the right side of the frame
• Large pale mass - a prominent, smooth, pale/pearly, glistening, edematous rounded structure occupies most of the nasal lumen

1. Nasal Polyp(s) - The large pale, translucent, grape-like mass with a glistening surface is highly characteristic of a nasal polyp. Its pale, pearly appearance distinguishes it from normal turbinate tissue (which is pink). It appears to arise from the middle meatus/lateral nasal wall area.
2. Significant nasal airway obstruction - The polyp occupies a substantial portion of the nasal lumen, causing marked mechanical narrowing.
3. Mucoid/serous secretions - Thin, clear, glistening secretions are visible on the mucosal surfaces. No thick purulent (pus-like) discharge.
4. Mucosal congestion - The surrounding mucosa is moist and mildly hyperemic (reddened/congested).
5. Endoscopic instrument - A metallic suction tip or probe is visible entering from the lower portion of the frame, being used to probe/assess the mass.

Image 2 (Second Side - contralateral nasal cavity)

• Nasal septum - seen on the left, smooth and relatively straight
• Inferior turbinate - large, pink, rounded structure occupying the right and central portion of the frame
• Common meatus/nasal passage - the dark space between septum and turbinate

1. Inferior turbinate hypertrophy - The inferior turbinate is markedly enlarged and protrudes medially, causing significant narrowing of the nasal passage. This is a common cause of nasal obstruction.
2. Mucosal congestion and edema - The turbinate mucosa is pink, moist, and swollen (edematous), consistent with inflammatory/allergic changes.
3. Mucus strand (mucus bridge) - A thin white mucus bridge is visible stretching horizontally across the airway, connecting the septum to the turbinate. This is characteristic of ongoing mucosal secretion.
4. No polyps visible on this side - the structure is broad-based, pink, and mucosal in appearance (normal turbinate color), not the pale, translucent, gray-white appearance of a polyp.
5. No purulent discharge visible - secretions are thin and clear/mucoid.

Summary Table

Clinical Interpretation (MBBS Level)

• Bilateral nasal disease - polyp on one side + turbinate hypertrophy on the other
• Chronic rhinosinusitis with nasal polyposis (CRSwNP) - the most common context for unilateral or bilateral nasal polyps, often associated with allergic rhinitis, aspirin sensitivity, or asthma
• Allergic rhinitis - as the underlying cause driving turbinate hypertrophy and polyp formation bilaterally
• Differential diagnoses for the polyp include antrochoanal polyp (if it arises from the maxillary sinus and extends posteriorly) or, less commonly, inverted papilloma or benign/malignant tumor (though appearance here is consistent with benign polyp)
