Abstract
Adenoid, a nasopharyngeal lymphoid tissue forming a part of the Waldeyer's ring, was initially described in 1868 by Meyer. Adenoid hypertrophy (AH) can result in upper airway obstruction in children. Children with this condition present with symptoms of chronic nasal obstruction, rhinorrhoea, mouth breathing, snoring, recurrent sinusitis, and recurrent otitis media with effusion. Adenoidectomy is one of the most common surgical procedures performed in children, either alone or in conjunction with tonsillectomy or grommet insertion. The conventional adenoidectomy using curette is performed blindly by most surgeons without visualising the nasopharynx; which leads to uncommon complications such as inadequate adenoid tissue removal, eustachian tube scarring, bleeding and nasopharyngeal stenosis. This has lead to development of alternate surgical methods, which has been made possible with the advent of rigid nasal endoscopes, cold light source, fibre optics and powered instruments.
