Title: Double-blind, Randomized, Placebo Controlled Study Evaluating the Efficacy of Aerosal® in the Treatment of Sub-Obstructive Adenotonsillar Hypertrophy and Related Diseases
Brief Summary: The purpose of this study is to evaluate the efficacy of Aerosal® compared to a placebo treatment in the prognosis of sub-obstructive adenotonsillar hypertrophy present for at least six months.


Options:
A: Inclusion Criteria:

1. Ages 5.0 to 9.99 years at time of screening.
2. Diagnosed with Obstructive Sleep Apnea defined as: Obstructive Apnea Index (OAI) ≥ 1 or Apnea Hypopnea Index (AHI) ≥ 2, confirmed on nocturnal, laboratory-based PSG and Parental report of habitual snoring (on average occurring \>3 nights per week).
3. Tonsillar hypertrophy ≥ 1 based on a standardized scale of 0-4: 0 = surgically absent, 1 = taking up \< 25% of the airway, 2 = 25 - 50 % of the airway,3 = 50 - 75 % of the airway, 4 = \> 75% of the airway
4. Deemed to be a surgical candidate for AT by Ear, Nose and Throat specialist (ENT) evaluation.

Exclusion Criteria:

1. Recurrent tonsillitis defined as: \>3 episodes in each of 3 years, 5 episodes in each of 2 years, or 7 episodes in one year
2. Craniofacial anomalies, including cleft lip and palate or sub-mucosal cleft palate or any anatomic or systemic condition which would interfere with general anesthesia or removal of tonsils and adenoid tissue in the standard fashion
3. Obstructive breathing while awake that merits prompt AT in the opinion of the child's physician
4. Severe OSAS or significant hypoxemia requiring immediate AT as defined by: OAI\>20 or AHI\>30, desaturation defined as oxygen saturation (SaO2) \<90% for more than 2% sleep time
5. Apnea hypopnea indices in the normal range (OAI \< 1 and AHI \<2)
6. Evidence of clinically significant cardiac arrhythmia on PSG: Non-sustained ventricular tachycardia Atrial fibrillation, Second degree atrioventricular (AV) block: Sustained bradycardia \< 40 bpm (\> 2 minutes, Sustained tachycardia \> 140 bpm (\> 2 minutes)
7. Extremely overweight defined as: body mass index \> 2.99 age group and sex-z-score
8. Severe health problems that could be exacerbated by delayed treatment for OSAS Including: Doctor-diagnosed heart disease or cor pulmonale, history of Stage II Hypertension (HTN) defined as \> 99% percentile plus 5 mmHg for either systolic or diastolic, based on the age, gender, and height and/or requiring medication, therapy for failure to thrive or short stature, psychiatric or behavioral disorders requiring or likely to require initiation of new medication, therapy, or other specific treatment. School aged children, parental report of excessive daytime sleepiness defined as unable to maintain wakefulness, at least three times per week, in routine activities in school or home, despite adequate opportunity to sleep.
9. Severe chronic health conditions that might hamper participation including: severe cardiopulmonary disorders, sickle cell anemia, poorly controlled asthma, epilepsy requiring medication, diabetes (type I or type II) requiring medication, conditions likely to preclude accurate polysomnography (e.g. severe uncontrolled pain),mental retardation or enrollment in a formal school Individual Educational Plan (IEP) and assigned to a self-contained classroom for all academic subjects, history of inability to complete cognitive testing and/or score on the Differential Ability Scale (DAS) II of ≤ 55, chronic infection or HIV
10. Known genetic, craniofacial, neurological or psychiatric conditions likely to affect the airway, cognition, or behavior
11. Current use of one or more of the following medications: psychotropics, hypnotics,hypoglycemic agents or insulin,antihypertensives,growth hormone, anticonvulsants,anti-coagulants,daily oral corticosteroids, daily medications for pain
12. Previous upper airway surgery on the nose, pharynx or larynx, including tonsillectomy. Ear surgery and/or pressure equalizing (PE) tubes are not exclusion criteria
13. Receives Continuous Positive Airway Pressure (CPAP) treatment
14. A parent or guardian who cannot accompany the child on the night of polysomnogram (PSG)
15. A family planning to move out of the area within the year
16. Female participants only: Parental report that child has reached menarche
B: Inclusion Criteria:

* Sub-Obstructive Adenotonsillar Hypertrophy lasting from at least six months and associated with sleep disordered breathing (respiratory pauses or sleep-apnea) and/or recurrent sero-mucus otitis
* Suspension for more than 3 months from the date of any immunosuppressive treatments (cyclosporin, systemic steroids)

Exclusion Criteria:

* Patients with acute bronchopulmonary disease, tuberculosis, severe hypertension, hyperthyroidism, cancer (chemotherapy), intoxication, heart failure, bronchial asthma.
* Iodine allergy
C: Inclusion Criteria:

* Symptomatic snoring children \> 2 years of age and \< 10 years of age, who snore and have an apnea hypopnea index (AHI) \>2/hrTST (hour total sleep time), and in whom T\&A is therefore contemplated. Also among these, we will include children referred for evaluation for snoring who have a history of allergic rhinitis.

Exclusion Criteria:

* Hypersensitivity to montelukast
* Immunodeficiency or immunosuppressant therapy
* Craniofacial, neuromuscular, syndromic or defined genetic abnormalities
* Acute upper respiratory tract infection
* Systemic corticosteroid therapy or antibiotic therapy in the 2 weeks previous to the study
* Children who already had adenotonsillectomy.

In addition, children chronically receiving oral antihistamine preparations or nasal decongestants will be required to continue using these medications throughout the duration of the study. Patients receiving immunotherapy will continue on the same regimen without escalation of dose and frequency throughout the duration of the study. In addition, patients with severe OSA who in the opinion of their treating physicians require early surgical intervention for their OSA will be excluded from eligibility to the study.
D: Inclusion Criteria:

* Children \>6 years of age and \< 12 years of age, who snore and have an apnea hypopnea index (AHI) \< or equal 7 or Respiratory arousal index \> or equal 2

Exclusion Criteria:

* Hypersensitivity to budesonide
* Recent nasal trauma
* Nasal surgery or nasal septum perforation
* Current therapy with drugs interacting with budesonide (erythromycin clarythromycin, ketoconazole and cimetidine)
* Immunodeficiency or immunosuppressant therapy
* Craniofacial, neuromuscular, syndromic or defined genetic abnormalities
* Acute upper respiratory tract infection
* Systemic corticosteroid therapy or antibiotic therapy in the 2 weeks previous to the study, and
* Children who already had adenotonsillectomy in the past 12 months.
