ClinicalTrials.gov Identifier:	NCT00737906

Purpose

The primary goal of this post-marketing surveillance study is to assess whether surgical turbinate reduction performed using a Coblation® device is associated with reduced nasal obstruction symptoms.

Primary Outcome Measures:

Change in nasal obstruction symptoms at 6-weeks post surgery as measured using a validated health-related quality of life questionnaire (SN5) compared to nasal obstruction symptoms measured before surgery using the same questionnaire. [ Time Frame: 6 weeks, 6 months, 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Morbidity by determining the frequency, type, and severity of any observed adverse events through 12 months following surgical treatment. [ Time Frame: Through 12 months ] [ Designated as safety issue: Yes ]
To assess durability of treatment using: a. Self-reported obstructive symptoms measures b. Physical examination measures, c. Acoustic rhinometry measures, d. Blinded evaluation of anterior rhinoscopy images [ Time Frame: 6 weeks, 6 months, 12 months ] [ Designated as safety issue: No ]

Estimated Enrollment:	30
Study Start Date:	October 2007
Estimated Study Completion Date:	December 2009
Estimated Primary Completion Date:	October 2009 (Final data collection date for primary outcome measure)

Detailed Description:

Chronic rhinitis, or inflammation of the nasal mucosa, is one of the most common causes of nasal obstruction in the pediatric population. Chronic rhinitis may result in mucous gland hypertrophy, engorgement of the vascular system and deposition of collagen in the nasal mucosa. These changes occur most prominently in the inferior turbinate, causing enlargement and nasal obstruction. In children, inferior turbinate hypertrophy is associated with a greater degree of nasal obstruction relative to adults because of their small nasal anatomy.

Cases that do not respond to conservative treatments may be considered for one of many surgical procedures, including turbinate excision, submucosal resection, submucosal cautery, laser treatment, cryosurgery, powered microdebridement, or radiofrequency-based ablation. Clinical studies have shown that bipolar radiofrequency-based plasma (Coblation®) devices are capable of creating focal submucosal lesions with minimal or no damage to structures adjacent to the treated area. At present, however, this technique has not been formally evaluated in children. This study will investigate whether surgical turbinate reduction performed using a Coblation device is associated with reduced nasal obstruction symptoms that has failed to improve with other treatment methodologies.

Eligibility

Ages Eligible for Study:	6 Years to 17 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Patient is >=6 and <=17 years old.
Patient has had symptoms of nasal obstruction for >=6 months.
Patient has nasal obstruction symptoms unresponsive to at least 8 weeks of documented maximum medical management consisting of an oral antihistamine (e.g., Claritin, Allegra), a nasal corticosteroid (e.g., Nasonex) and environmental controls where possible.
Patient has bilateral hypertrophied inferior turbinates (by nasal examination), without other mass effects contributing to nasal obstruction as evidenced by CT scan of the nasal cavity and paranasal sinuses at least 90 days prior to enrollment.
Patient agrees to participate in the clinical study and to complete all required visits and evaluations.
Patient (or guardian) must sign IRB approved informed consent form.

Exclusion Criteria:

Patient has identifiable structural deformities other than turbinate hypertrophy that may contribute to nasal or upper airway obstruction including:
- Septal deviation
- Concha bullosa
- Enlarged adenoids or tonsils
- Nasal polyps
- Nasal valve collapse.
Patient has active or chronic upper airway infection that may contribute to nasal obstruction.
Patient has coagulation disorder or patient is receiving anti-coagulants, which cannot be safely stopped 5 days prior to surgery.
Patient has systemic disease affecting the nasal passage.
Patient has a septal perforation.
Patient has had a previous turbinate surgery within 1 year of enrollment.
Patient has had sinus surgery within 6 months of enrollment.
Patient has had an adenoidectomy within 3 months of enrollment.
Patient is incapable of understanding or responding to the study questionnaires.
Patient is participating in another clinical study.
