title: Partial adenoidectomy by suction diathermy in children with cleft palate, to avoid velopharyngeal insufficiency.
abstract: OBJECTIVE
  Adenoidectomy is indicated for the relief of paediatric nasal obstruction, sleep-disordered breathing and otitis media with effusion (OME). Velopharyngeal insufficiency (VPI) is a rare complication. The main risk factor is the presence of pre-existing velopharyngeal closure-impaired mechanisms, including submucosal or overt cleft palate. Despite possible benefits, adenoidectomy is frequently withheld in such children to avoid VPI. This study aims to demonstrate the efficacy and safety of partial adenoidectomy using suction diathermy in children who previously underwent overt cleft palate repair during infancy, to allow selective resection of tissue and symptom resolution without producing VPI.
  
  
  METHODS
  Since 1994, 18 patients with previously corrected overt cleft palate have undergone partial adenoidectomy at this centre, for the treatment of nasal obstruction or sleep-disordered breathing, with or without OME. Three had existing VPI following their cleft correction surgery. Selective resection of the adenoid was performed transorally under indirect vision, using a malleable suction coagulator. This allowed exposure of the posterior choanae, leaving the remaining adenoid bulk intact.
  
  
  RESULTS
  Patients were followed up at 4 weeks, and subsequently at regular intervals (total follow up 30-180 months, median 92 months), including perceptual speech assessment in all cases. All demonstrated symptomatic improvement with respect to the original indications for surgery. None developed worsening hypernasal speech or other features of VPI, and there were no cases of symptomatic adenoidal re-growth.
  
  
  CONCLUSIONS
  Partial adenoidectomy, employing a variety of methods, has been used successfully in children with submucosal cleft palate. This study demonstrates the safe and effective use of suction diathermy to enable partial adenoidectomy in children who have previously undergone surgical correction of overt cleft palate, allowing symptom resolution without producing VPI.
