Inferior turbinate debriding technique shows long-term efficiacy for treatment of nasal obstructions

Medtronic : 04 March, 2008  (New Product)
Medtronic has announced results of a study that shows in one of the longest-running studies on nasal obstruction, patients treated with a microdebriding turbinoplasty technique had excellent resolution of their nasal obstruction.
The long-term outcome for patients was similar to subjects with no nasal obstruction.

The paper entitled ‘Inferior Turbinate Debriding Technique: Ten-Year Results’, was written by Carlos Yanez, MD, FACS, from the American British Medical Center.

The results were maintained over the 10 years of the study. In the study, Dr Yanez followed 341 patients who were treated with microdebrider turbinoplasty and 308 normal subjects not treated, but monitored, during the 10-year period.

Of those in the study group, 91.3 percent remained free of obstruction after 10 years. These results were compared to the normal subjects who had no nasal obstruction initially. After 10 years, 96.7 percent of normal subjects were free of nasal obstruction.

The powered inferior turbinoplasty technique can be performed using the Medtronic XPS 3000 and Straightshot M4 Microdebrider. Manufactured by the ENT business at Medtronic and available in the USA, the system features a tiny, rotating tip that allows the surgeon to remove tissue more precisely than traditional surgery tools. Using the Medtronic microdebrider, surgeons can remove enough tissue to correct the nasal obstruction while preserving the mucous lining and normal turbinate function.

Preservation of mucosa is considered an important factor in better postoperative outcomes in patients who have undergone nasal surgery. The technique is associated with very low relapse rates (better long-term effectiveness) as presented by Sacks.

The Yanez study confirms the long-term efficacy of the procedure following a much longer period than any other published turbinoplasty technique of any type. “Nasal obstruction remains a significant problem and there are many techniques to treat the condition,” said Yanez. “However, there are no existing treatments that have proven to be this effective during this long period of time. This study confirms that microdebrider turbinoplasty is efficacious long term. The microdebriding technique significantly improves patient quality of life and offers relatively few postoperative complications.”

Symptoms of nasal obstruction can be linked to multiple causes, of which deviations of the septum and inferior turbinate hypertrophy are the most common. Other techniques for reducing nasal obstruction symptoms may include complete or partial turbinectomy, manual instrumentation, radiofrequency energy or cauterisation, often with septoplasty (straightening of the nasal septum). However, the other treatment techniques have been linked to numerous complications, somewhat unpredictable outcomes and high relapse rates.

The research study was published in the February issue of the Archives of Otolaryngology–Head and Neck Surgery.
