Lingual TonsilsLingual Tonsils
• Hypertrophy of lingual tonsils in 62% of persons with laryngoscopic signs of reflux and in 75% of persons with pharyngolaryngeal symptoms of LPR.
• Although the lymphoid tissue in Waldeyer's ring tends to decrease with advancing age, the lingual tonsil may increase in size.
• The most important cause of lingual tonsil hypertrophy is the occurrence of compensatory hyperplasia following adenotonsillectomy.

ComplicationsComplications• Noniatrogenic complications after adenoidectomy
– Regrowth of adenoid tissue, particularly in very young children, which may require revision (secondary) adenoidectomy.
– Hypernasality, because of temporary pain splinting. Persistent hypernasality is rare and probably caused by unrecognized pre-existing velopharyngeal weakness.
– Atlantoaxial subluxation (Grisel’s syndrome), which presents with persistent torticollis 1-2 weeks after surgery.
• Iatrogenic complications after adenoidectomy include– Dental injury, from intubation or the mouth gag – Nasopharyngeal stenosis, caused by excessive
tissue removal. – Eustachian tube injury
