Cartilaginous Septum Crura www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ

The Membranous Septum (Mobile Septum) Anterior to the end of the septal cartilage. It is formed by skin and subcutaneous tissue of the nasal columella. www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ

Bony Septum Composed of two major elements: The Vomer The Perpendicular plate of the Ethmoid www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ

The Vomer Develops from connective tissue membrane on each side of the septal cartilage. For the opposing lamellae of the vomer to fuse, the intervening cartilage must be absorbed completed by mid adult hood. www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ

Septal Positions Septum bows entirely into one nasal cavity Double buckling occurs with an S‑shaped deformity affecting both cavities. The septal cartilage is often dislocated out of the midline groove of the maxillary crest. www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ

Asymmetry of the Nasal Septum Approximately 80 % of humans have some deformity of the nasal septum. Any or all parts of the septum except for the posterior free border at the choanae, where it is always midline. A common area of deflection is along the articulation between the vomer and the perpendicular plate of the ethmoid www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ

Septal Deviations • Types: traumatic and congenital • Common Defects: spurs, crests, dislocation of quadrangular septal cartilage, buckling • SSx: unilateral nasal obstruction (may be bilateral), hyposmia, epistaxis, recurrent sinusitis • Dx: anterior rhinoscopy www.

Caudal End Dislocation www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ

Spurs Ridge like deflections and spurs may occur there, even if the rest of the septum is straight. www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ

Surgical Management • Submucous Resection: obstructing cartilaginous and bony portion of the nasal septum is removed • Septoplasty: removal of deviated cartilaginous and bony septum with reinsertion after remodeling and repositioning (preserves support system, less risk of perforation) www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ

INDICATIONS • nasal obstruction (deviated nasal septum), epistaxis, chronic sinusitis (when septum is obstructing), access for transseptal sphenoidotomy, headache from an impacted spur septal neoplasia (rare) www. Rhinologychair. org Rhinology Chair ﺍﻧﻔﻴﺔ
