چکیده
Tonsillectomy is one of the most frequently performed surgical operations in children. According to the Department of Health Hospital Episode Statistics (http://www.hesonline. nhs.uk), 25 000 tonsillectomies and 6500 adenoidectomies were performed in children under 15 years of age in England in 2003. The tonsils and adenoids are lymphoid tissues forming part of the Waldeyer’s ring encircling the pharynx. They appear in the second year of life, are largest between 4 and 7 years of age and then regress. Children with adenotonsillar hypertrophy can present with nasal obstruction, recurrent infections, secretory otitis media and deafness (secondary to Eustachian tube dysfunction), and obstructive sleep apnoea (OSA). Tonsillectomy is indicated in children with recurrent tonsillitis if they have had five or more episodes of sore throat per year because of tonsillitis, or if symptoms have persisted for at least 1 year and are disabling, that is, interfering with normal functioning (SIGN publication no. 34, available from http://www. sign.ac.uk). Other indications for tonsillectomy include chronic tonsillitis, peritonsillar abscess, and OSA. Adenoidectomy is indicated when there is evidence of enlarged adenoids causing nasal obstruction, OSA, or hearing loss. In the presence of OSA, adenotonsillectomy eliminates obstruction in 85 – 95% of children, yielding improvement of symptoms and quality of life.
