Nasal septum: defect

Contributor(s): Stephen Adams, Paddy Dixon, Nicola Menzies-Gow

Introduction

  • Signs: abnormal respiratory noise.
  • Cause: thickening or deviation of nasal septum. Usually a congenital defect. Other etiologies include trauma, severe respiratory infection, 'cystic degeneration' (nutritional hyperparathyroidism) and amyloidosis.
  • Diagnosis: history, signs, radiography, endoscopy.
  • Treatment: septal resection. Antifungal medication required if evidence of mycosis.
  • Prognosis: fair.

Pathogenesis

Etiology

  • Congenital deformity of the nasal septum is the most common finding.
  • Other etiologies include granulomatous thickening secondary to evere respiratory infection, 'cystic degeneration' (now believed to be due to nutritional hyperparathyroidism) and amyloidosis.

Pathophysiology

  • Thickening and/or deviation of nasal septum.
  • Results in abnormal respiratory noise at exercise.
  • May also result in airway obstruction and therefore exercise intolerance.

Timecourse

  • Depends on etiology.
