Primary Outcome Measures:

Change From Baseline in Adenoid/Choana (A/C) Index Grade [ Time Frame: Baseline (visit 2), Weeks 4 (visit 3), Week 8 (visit 4) ] [ Designated as safety issue: No ]
Changes in adenoid size were assessed by nasopharyngoscopic examination and were determined using the Adenoid/Choana (A/C) Index. Grades were assigned to intervals of A/C ratio percentages: grade I (0-25%), II (26-50%), III (51-75%) and IV (76-100%). Changes in adenoid size were expressed as the mean difference between grades at baseline and study visit. Positive values indicated a decrease in adenoid size, a 0 value indicated that size remained the same, and negative values indicated an increase in adenoid size.

Secondary Outcome Measures:

Total Severity Symptom Scores: Morning and Evening (AM & PM) [ Time Frame: Baseline (Visit 2), Week 4 (Visit 3), Week 8 (Visit 4) ] [ Designated as safety issue: No ]
Symptoms were assessed by whole-number linear scale to grade their severity. Scores were recorded AM & PM (12 hours later) & were based on severity within 12 hours of prior recording. The following symptoms were evaluated: Snoring; Nasal obstruction & discharge; Breathing difficulty; Oral respiration; Ear pain. Severity was graded according to the following scale: 0=absent; 1=mild; 2=moderate; 3=severe. Severity was scored individually and summed to obtain the Total Symptom Severity Score. The maximum total score possible was 36 daily; 18 for both AM (6 symptoms times max severity of 3)and PM.
Total Frequency Symptom Scores: AM & PM [ Time Frame: Baseline (Visit 2), Week 4 (Visit 3), Week 8 (Visit 4) ] [ Designated as safety issue: No ]
Symptoms were assessed by whole-number linear scale to grade their frequency. Scores were recorded AM & PM (12 The following signs/symptoms were evaluated:

Snoring; Nasal obstruction; and nasal discharge; Breathing difficulty; Oral respiration; Ear pain.

Frequency was graded according to the following scale:

0=absent; 1=intermittent; 2=persistent

The frequency of symptoms was scored individually and summed to obtain the Total Frequency Symptom Score. The maximum total score possible was 24 daily; 12 for both AM (6 symptoms times max frequency of 2) and PM.

PSQ consists of 90 variables divided into 3 different factors:snoring, somnolence, and behavior. All positive Snoring and Somnolence answers scored with Yes=1 and No=0, and scores averaged to obtain a total score between 0.00 and 1.00. Behavior factor scored between 1-3, and scores averaged for total score of 1 to 3. Increased scores indicate increasing abnormality of sleep. Based on determined cut-offs, participants were categorized as having mild, moderate, or severe discomfort due to interference of sleep.
Quality of Life Questionnaire (PedsQL) Total Score (Ages 2-4) [ Time Frame: Baseline (Visit 2), Week 4 (Visit 3), Week 8 (Visit 4) ] [ Designated as safety issue: No ]
The impact on quality of life (QOL) was measured by a general pediatric health questionnaire. Versions were self-administered & answered by participants' parents. This modular instrument consists of 21 items using a 5-point scale: from 0 (never) to 4 (almost always). Items are reversed scored and linearly transformed to a 0-100 scale as follows: 0=100, 1=75, 2=50, 3=25, 4=0. 4 dimensions (physical, emotional, social, & school functioning) are scored. Total score is sum of all the items over the number of items answered on all the scales. Higher scores indicate a better health related QOL.

The impact on quality of life (QOL) was measured by a general pediatric health questionnaire. Versions were self-administered & answered by participants' parents. Questionnaire consists of 23 items using a 3-point scale: from 0 (not at all), 2 (sometimes), 4 (a lot). Items are reversed scored and linearly transformed to a 0-100 scale as follows: 0=100, 1=75, 2=50, 3=25, 4=0. 4 dimensions (physical, emotional, social, & school functioning) are scored. Total score is sum of all the items over the number of items answered on all the scales. Higher scores indicate a better health related QOL.

18 items of the survey were graded on a 7-point ordinal scale. Caregivers were asked to describe how often in the last 4 weeks had the child exhibited specific symptoms according to the following scale: 1: none of the time; 2: hardly any of the time; 3: a little of the time; 4: some of the time; 5: a good bit of the time; 6: most of the time; 7: all of the time. All scores were summed (total score: 18-126).

Grading was as follows:
- Scores < 60 suggest a slight impact on health related quality of life (HRQL)
- Scores 60-80 suggest a moderate impact
- Scores over 80 suggest a great impact
