Abstract

FRAGA, José C.; SCHOPF, Luciano; VOLKER, Vanessa  and  CANANI, Simone. Endoscopic supraglottoplasty in children with severe laryngomalacia with and without neurological impairment. J. Pediatr. (Rio J.) [online]. 2001, vol.77, n.5, pp. 420-424. ISSN 0021-7557.  http://dx.doi.org/10.1590/S0021-75572001000500014.

OBJECTIVE: to describe indications and results of supraglottoplasty for severe laryngomalacia in children with or without neurological impairment. METHODS: Eight children with severe laryngomalacia submitted to endoscopic supraglottoplasty were retrospectively studied. Four had neurological impairment (male, mean age 6 years), and 4 did not present neurological problems (3 female, mean age 11.5 months). Surgery indications were respiratory distress, feeding difficulties, failure to thrive, and low oxygen saturation. Polysomnographic evaluation was carried out on the last 2 children, showing abnormal oxygen saturation, obstructive apnea, and hypoventilation. All children received preoperative antibiotics and corticosteroids. RESULTS: all children without neurological impairment had significant relief of symptoms. Children with neurological impairment had different outcome: one needed tracheotomy immediately after surgery due to edema and supraglottic granulation tissue. The other three children presented initial relief of symptoms, but subsequent follow-up showed progressive airway obstruction: one needed another endoscopic surgery 6 months later; other needed tracheotomy 7 months later. The children who were not submitted to tracheostomy presented persistent severe airway obstruction. No endoscopic surgery complication was observed. CONCLUSIONS: 1) Endoscopic supraglottoplasty is well tolerated and does not present complications when used in children; 2) Endoscopic supraglottoplasty was efficient in the treatment of children with severe laryngomalacia and in without neurological impairment; however, supraglottoplasty did not resolve airway obstruction in children with neurological impairment.
