Brief Summary:
Asthma in children is recognized as a disease area with a high medical need. As the investigators move into this field it is necessary to improve the investigators knowledge of upper airway anatomical structure in paediatric patients. This study will provide airway/facial morphologies from controlled asthmatic patients. Limited facial morphology can be used in order to build models to study the delivery of medication through a device that requires for example a facemask. In this study the anatomical structure of the upper airway and the facial geometry will be evaluated using a Cone Beam Computed Tomography (CBCT) scan. The scan will be taken in a population of 20 asthmatic children between 6 and 12 years old.

Intervention Details:
  • Radiation: Cone Beam Computed Tomography
    CBCT scan of upper airway at visit 1
    Other Name: CBCT

Primary Outcome Measures :
  1. Cone Beam Computed Tomography [ Time Frame: At day 1 ]
    The primary objective of this study is to provide data from CBCT scans to evaluate the anatomical structure of the upper airway and the facial geometry of children. The provided data will enable further work in the mapping of the upper airway and deliver 3D geometries.

  • Parents or guardian must be able to understand and complete to protocol requirements, instructions and protocol-stated restrictions. Parents/guardians must give written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • Diagnosis of asthma at least 6 months previous prior to screening.
  • Children must be controlled on their existing asthma treatment at screening as defined by ACT or childhood ACT score of ≥ 20 and PEF>80%.
  • Children must be taking a stable regime of SABA/ LABA on an as need basis, with or without Leukotriene Antagonists and inhalation corticosteroids.
  • All children must be competent to perform the required tests.
  • Children must be available to complete the study and comply with study primary objective investigations.
  • Children must be able to withhold from short acting bronchodilators for 6 hours.

Exclusion Criteria:

  • As a result of the medical interview, physical examination or screening investigations, the responsible physician considers the patient unsuitable for inclusion to the study.
  • Children who have a past or present disease, or have had previous surgery which as judged by the Investigator, may affect patient safety or influence the outcome of the study.
  • The child has received an investigational drug or participated in any other research trial within 30 days, or twice the duration of the biological effect of any drug (whichever is longer).
  • The child has had a respiratory tract infection within two weeks of the start of the study.
  • Children who have had an exacerbation of disease requiring hospitalization for > 24 hrs within four weeks prior to inclusion.
  • Children who are unwilling or unable to follow any of the procedures outlined in the protocol.
  • Child is mentally incapacitated.
