Inferior Turbinate Hypertrophy
Pathophysiology
Inferior turbinate hypertrophy can result from o Mucosal hypertrophy o Bony hypertrophy o Both
Bony hypertrophy causes a fixed structural obstruction and is best treated with surgery
More commonly, the problem is mucosal hypertrophy causing impingement on the nasal valve, increased nasal resistance, and nasal obstruction
This can be managed medically or surgically depending on the degree of hypertrophy and responsiveness to medical management
Aetiology
Post rhinoplasty
Allergic rhinitis
Vasomotor rhinitis
Chronic rhinosinusitis
DNS to opposite
Congenital
Rhinitis medicamentosa
Pregnancy
OCPs
Hypothyroidism
Wegener’s granulomatosis
Sarcoidosis
History
Nasal obstruction
Alteration or unilaterality may indicate a dynamic versus structural problem
Features of allergic rhinitis vasomotor rhinitis
Nasal decongestant usage
H/o nasal surgery
Examination
Patency of the nasal valve cottle
Anterior rhinoscopy o Septal deformities o Inferior turbinate hypertrophy o Apply topical decongestant to evaluate the response of the turbinate mucosa assist
in delineating mucosal versus bony hypertrophy
Rigid or flexible nasal endoscopy
Purulent drainage may indicate sinusitis
Signs of other systemic disorders (wegener’s, hypothyroidism)
Investigations
Xray PNS
CT is not indicated in the workup of inferior turbinate hypertrophy alone. However, if a CT scan of the head, facial bones, or sinuses has been obtained for other reasons, it may provide useful information bony versus mucosal hypertrophy
Rhinomanometry / acoustic rhinometry
Allergy testing

Medical Therapy
Therapy for allergic and vasomotor rhinitis
Submucosal injection of corticosteroids has been tried results are rapid but temporary relief incidence of permamnent blindness noticed therefore now abandoned
Surgical Therapy
Surgical therapies o Reposition the turbinate o Address mucosal hypertrophy o Address bony hypertrophy o Address both mucosal and bony hypertrophy
Repositioning the turbinate o Laterally within the nasal valve area is accomplished by lateral out-fracture o This technique does not address either mucosal or bony hypertrophy but rather the
spatial relation of the inferior turbinate within the nasal valve
Mucosal hypertrophy o Submucosal techniques
Designed to produce submucosal tissue injury while preserving overlying mucosa
Resultant tissue loss and subsequent scarring lead to a reduction in bulk of the inferior turbinate mucosa and submucosa
Techniques
Submucosal diathermy
Microdebridder
Cryotherapy
Coblation
Radiofrequency
Ultrasonic aspirator

o Surface electrocautery o Laser vaporization
Bony hypertrophy o Submucous resection
Periosteal flap is developed Underlying bone removed Flap is replaced
Mucosal and bony hypertrophies o Best dealt with via a partial inferior turbinectomy or inferior turbinoplasty
. Partial turbinectomy Inferior turbinoplasty.
Complications
Epstaxis Synaechiae Dryness and crusting / atrophic rhinitis Turbinate bone necrosis and sequestrum requires removal of sequestrum
