When is a turbinectomy indicated?

When is a turbinectomy indicated?

Nasal obstruction is the most common complaint treated by otolaryngologists.

Turbinectomy or conchotomy is the surgical removal of an abnormally enlarged turbinate, which opens up the nasal passages by removing bone and soft tissue from inside the nose to improve breathing.

The turbinate or conchae is a bone in the nose; it is an extension of the ethmoid bone and is situated along the sidewall of the nose, covered by mucous membrane.

 It may be warranted in cases in which the upper airway is obstructed due to:
  • deviated nasal septum
  • swelling of the turbinate due to allergy, chronic inflammation, or chronic sinusitis
  • nasal polyps or other tumour obstructing the nose
  • swelling of the adenoids




When a 'turbinate bone' or 'conchae' is abnormally enlarged, it produces an ‘empty nose syndrome’, with symptoms like chronic nasal dryness, inflammation, 'paradoxical obstruction' (loss of airflow sensation) leading to breathing difficulties, grogginess and dizziness, and often pain and repeated nasal infections. These symptoms have a significant impact on the patient’s quality of life and sense of well-being. It can produce difficulty concentrating (appears in the medical literature as 'aprosexia nasalis'), pre-occupation with symptoms, anxieties and often clinical depression.[1]
The goals of nasal airway surgery include the following: to improve airflow through the nose, to control nosebleeds, to enhance visualization of the inside of the nose, to relieve nasal headaches associated with swelling of the inside of the nose, and to promote drainage of the sinus cavities. Nasal airway surgery is done through the nostrils without the need for external incisions.
Over resection of the inferior turbinates in the nose may lead to chronic nasal dryness, chronic mucosal inflammation, squamous metaplasia, mucosal atrophy and in rare cases even to full blown atrophic rhinitis. The remaining mucosal structures (the septum and the remaining turbinates) often hypertrophy and complicate diagnosis.[2][3][4][5][6]
