Obstruction of the nose is the most common nasal symptom. It may be unilateral “more important” or bilateral.
Definition: Blockage of the nasal cavity that may or may not affect the breathing quality.
Causes of Unilateral Nasal Obstruction:
1. Congenital:
- Unilateral choanal atresia “catheter test & CT - could be accidentally discovered in older children”.
- Meningocele or meningo-encephalocele (CT & MR).
2. Developmental:
- C- shaped septal deviation “ persistent not seasonal or positional”.
3. Traumatic:
- Accidental: Fractured nasal bones.
- Surgical: Adhesions.
- Foreign body: In children & mental patients. N.B. Batteries are more harmful.
4. Inflammatory:
5. Neoplastic:
- Benign: Inverted papilloma ( Biopsy).
- Malignant tumors: e.g. adenocarcinoma limited to one side (Biopsy).
6. Miscellaneous:
- Antrochoanal Polyp “usually adolescent or young adult” (CT).
- Nasopharyngeal angiofibroma, in adolescent males “epistaxis is a more common presentation”.
Causes of Bilateral Nasal Obstruction:
a. Congenital:
- bilateral choanal atresia (emergency in newly born).
b. Developmental:
- S-shaped septal deviation “persistent not seasonal or positional”.
c. Traumatic:
- Accidental: Fractured nasal bones.
- Surgical: Bilateral adhesions.
- Septal hematoma “may be accidental or post-septal surgery”.
d. Inflammations:
- Non-specific: hypertrophic inferior turbinates or atrophic rhinitis “loss of sensation of air flow”.
- Specific: scleroma and lupus “either mass effect or due to atrophic changes”.
e. Neoplastic:
- Large nasal tumor, which pushes or infiltrates the septum “either benign or malignant”.
f. Miscellaneous:
- Allergic rhinitis, vasomotor rhinitis and rhinitis medicamentosa.
- Bilateral sinonasal “allergic” polypi.
- Huge nasopharyngeal swellings:
- Adenoids, in children.
- Nasopharyngeal angiofibroma, in adolescent males “epistaxis is a more common presentation”
- Late carcinoma, in old age.
Key points
- Unilateral obstruction is a significant symptom & should be thoroughly examined and investigated.
- Always consider the age as some pathologies are peculiar to certain age groups.
Treatment of Nasal obstruction
- Treatment of the cause is the key.
- Decongestants relieve the obstruction till management of the cause.
- Local decongestants e.g Nasal drops.
- Systemic decongestants like "Pseudoephedrine".
