The primary surgical approach involves splitting the nasal bones to remove the cyst and its extension.

Differentiate between intranasal and extranasal nasal gliomas in terms of their typical locations.

Intranasal gliomas are located within the nasal cavity, while extranasal gliomas are found outside the nasal structures, typically on the nasal bridge or side of the nose.

Study Notes

External Conditions of the Nose

  • Infective Conditions:

    • Acute:
      • Furunculosis: Staphylococcal infection of hair follicles in the nasal vestibule. Symptoms include severe pain, fever, swelling, and tenderness.
      • Impetigo: Superficial bacterial infection of the skin, often caused by Staphylococcus aureus or Streptococcus pyogenes.
      • Erysipelas: Acute bacterial infection of the skin and subcutaneous tissue, typically caused by group A Streptococcus.
      • Herpes Simplex and Zoster: Viral infections that can manifest in the nasal region.
    • Chronic:
      • Vestibulitis: Repeated fissuring and crust formation in the nasal vestibule, often with bleeding.
      • Lupus Vulgaris: Chronic granulomatous infection caused by Mycobacterium tuberculosis.
      • Syphilis: Bacterial infection that can cause lesions on the nose.
      • Lupus Erythematosus: Autoimmune disease that can affect the nose.
      • Acne Rosacea: Chronic inflammatory skin disorder affecting the face, including the nose.

  • Neoplastic Conditions:

    • Papilloma: Benign growth of the skin or mucous membranes.
    • Rodent Ulcer: Malignant skin cancer, also known as basal cell carcinoma.
    • Keratoacanthoma: Benign, rapidly growing skin tumor.
    • Squamous Cell Carcinoma: Malignant cancer of the squamous epithelial cells.

  • Traumatic Conditions:

    • Fracture Nose: Break in the nasal bones.
    • Septal Hematoma: Collection of blood within the nasal septum.
    • Saddle Nose: Depression of the nasal bridge, often due to untreated septal hematoma.

  • Foreign Bodies in the Nose:

    • Rhinolithiasis: Nasal stones, often composed of calcium phosphate.
    • Myiasis: Infestation with fly larvae.
    • Rhinosporidiosis: Fungal infection, causing polyps in the nasal cavity.

Congenital Conditions

  • Posterior Choanal Atresia: Failure of the posterior nasal passage to open.

    • Incidence: 1 in 7000, female: male = 2:1
    • Aetiology: Embryonic failure of the bucconasal membrane to rupture.
    • Types: Bony, membranous, or mixed. Unilateral or bilateral.
    • Clinical Features: Unilateral: Asymptomatic at birth, later causing unilateral nasal discharge and obstruction. Bilateral: Emergency at birth, newborn is an obligate nasal breather and presents with pallor, cyanosis, nasal obstruction, and difficulty feeding. Other signs include bulging of the lateral nasal wall, facial asymmetry, high arched palate, and deformed or absent teeth.
    • Diagnosis: Mirror test, plastic catheter, cotton wool, fibreoptic endoscopy, contrast radiography, CT scan.
    • Treatment: Bilaterally: Maintain an oral airway. Definitive surgical removal of the atretic plate.
    • Surgical Approaches:
      • Transnasal: Perforation with a probe, electrocautery, laser, or burr followed by stent placement.
      • Transpalatal: Surgical approach via the palate.
    • Follow Up: Maintenance of the opening with regular bouginage.

  • Congenital Nasal Masses:

    • Nasal Dermoid: Sequestration of epithelial elements during fusion of the median nasal process.

      • Types: Simple (no external opening) or with sinus (external pit).
      • Clinical Features: Midline swelling, external pit, protruding hair.
      • Treatment: Excision, with neurosurgical approach if intracranial extension.

    • Nasal Glioma: Nipped off portions of encephalocele during embryonic development.

      • Types: Extranasal, intranasal, or both.
      • Clinical Features: Firm subcutaneous swellings.
      • Treatment: Surgical removal.

    • Nasal Meningoencephaloceles: Herniation of glial tissue and meninges through skull defect.

      • Clinical Features: Cystic mass, often over the root of the nose, connected to intracranial cavity, may enlarge during crying.
      • Treatment: Surgical excision, correction of associated anomalies.

  • Other Congenital Anomalies:

    • Agenesis of the Nose: Total or partial absence of the nose, treatment is reconstruction.
    • Cleft Nose: Range from minor notching to total midline division, often associated with cleft lip and palate, treatment is reconstruction.

Other Conditions of the Nose

  • Epistaxis: Nasal bleeding.
  • Affections of the Nasal Septum:
    • Deviated Nasal Septum (DNS): Displacement of the nasal septum.
    • Anterior Dislocation: Displacement of the septum from its normal position.
    • Septal Perforation Hole in the nasal septum.
    • Bleeding Polypus of the Septum: Benign growth on the nasal septum that can cause bleeding.

External Nose Conditions

  • Acute Vestibulitis:
    • Caused by staphylococcal infection
    • Presents with redness, excoriation, and fissuring of nasal vestibule skin
    • Symptoms: Severe pain, fever, swelling, and tenderness
    • Treatment: Broad-spectrum antibiotics, anti-inflammatory drugs, and antibiotic cream
    • Avoid squeezing or surgery to prevent cavernous sinus thrombosis
  • Chronic Vestibulitis:
    • Repeated fissuring with crust formation
    • Painful, may bleed with rubbing

Congenital Anomalies

  • Choanal Atresia:
    • Closed posterior nares, preventing nasal breathing
    • Incidence: 1 in 7000 births, female-to-male ratio 2:1
    • Etiology: Failure of bucconasal membrane to rupture during development
    • Types: Bony (90%), membranous (10%), or mixed; unilateral or bilateral
    • Unilateral: Asymptomic at birth, later causes unilateral nasal discharge and obstruction
    • Bilateral: Emergency at birth, presents with cyanosis, facial asymmetry, and possible palate deformation
    • Diagnosis: Mirror test, plastic catheter, cotton wool, fiberoptic endoscopy, contrast radiography, CT scan
    • Treatment: Oral airway until surgery; surgical removal of atretic plate, stent or dilation for maintenance
  • Nasal Dermoids:

  • Nasal Meningoencephaloceles:
    • Herniation of glial tissue and meninges through skull defect
    • Contain CSF and are connected to intracranial cavity
    • Present as cystic masses over the root of the nose or intranasal
    • Treatment: Surgical excision, correction of associated orbital or facial anomalies
  • Agenesis of the Nose:
    • Total or partial absence of the nose
