A retrospective review of the notes of 100 consecutive patients who had undergone aryepiglottoplasty for laryngomalacia, at Great Ormond Street Hospital for Children, was undertaken. Fifty-six were male, 44 female and 47 were under three months of age. Indications for surgery were oxygen desaturation below 92 per cent and feeding difficulties causing failure to thrive. Forty-seven patients had other pathology contributing to their airway compromise or feeding problems. Improvement in stridor after one month was achieved in 86/91 (94.5 per cent) being abolished completely in 50/91 (55 per cent). Of the 25 per cent of patients whose symptoms took more than one week to resolve, 16/22 (63.6 per cent) were later found to have a serious neurological condition. Feeding was improved in 42 of 58 patients (72.4 per cent) who had a pre-operative feeding difficulty. The complication rate was low, with only five out of 86 (10 per cent) experiencing initial worsening of the airway and six per cent having aspiration of early feeds before improvement occurred. Endoscopic aryepiglottoplasty remains the operation of choice for patients with severe laryngomalacia, however, in the presence of neurological disease surgery is less likely to be successful.
Cross-sectional imaging plays an indispensable complementary role to endoscopy in the pretherapeutic workup of laryngeal and hypopharyngeal cancer. Both computed tomography and magnetic resonance imaging are suitable for the detection of neoplastic cartilage invasion. Although MRI, due to its high negative predictive value, is now generally considered to be the most suitable imaging method for pretherapeutic evaluation of cartilage invasion CT continues to be commonly performed in many centers for practical reasons. Recent studies have shown that CT may yield acceptable sensitivity for neoplastic invasion of laryngeal cartilage if the diagnostic criteria are selected and combined appropriately. False positive results are inevitable with both CT and MRI because reactive inflammation may lead to overestimation of neoplastic cartilage invasion.
