Response to: Ultrasonographic assessment of tonsillar volume in children

Thank you for the opportunity to respond to this correspondence. The principle aim of our study was to assess the suitability and validity of ultrasound as an objective tool for measuring tonsillar size and volume in children. This was tested as a pilot study of children undergoing adenotonsillectomy or tonsillectomy alone for obstructive sleep apnoea syndrome (OSAS) or recurrent tonsillitis, respectively. History and clinical assessment with polysomnography, in cases of diagnostic uncertainty, remains the gold standard investigations for diagnosing obstructing sleep apnoea.
