CO2 laser supraglottoplasty for severe laryngomalacia: A study of symptomatic improvement
چکیده انگلیسی

SummaryObjectiveTo investigate post-operative symptom improvement in patients with severe laryngomalacia.Study designSevere laryngomalacia was diagnosed in 138 patients (average age of 6.97 months) by bronchoscopy. Laryngomalacia was defined by the direction of supraglottic collapse: type A (posterolateral), type B (complete), and type C (anterior). As multiple laryngomalacia types within an individual were common, patients were further categorized into group I (type A only), group II (type B or B + A), and group III (type C, C + A, or C + B + A). CO2 laser supraglottoplasty was performed. Improvements in inspiratory stridor, suprasternal retraction, substernal retraction, feeding difficulty, choking, post-feeding vomit, failure to thrive, and cyanosis were investigated. The presence of a symptom was scored as 1, and the absence as 0. The total score of symptoms was calculated for each patient. General medical history, age at time of surgery, type of laryngomalacia, post-operative intubation period, duration in ICU and dates of postoperative admission were recorded.ResultsOverall symptom improvement was observed in 82.6% of patients, with statistically significant resolution evident in group III (B-value = 0.79, 95% CI: −0.01, 1.59). Symptoms were not well improved in patients with cerebral palsy (n = 32, B-value = −1.02, 95% CI: −1.80, −0.25; p < 0.01). The two most improved symptoms were substernal retraction and suprasternal retraction, while the two least improved symptoms were choking and feeding difficulties.ConclusionCO2 laser supraglottoplasty is an effective treatment option for severe laryngomalacia, especially for group III laryngomalacia cases in the absence of cerebral palsy. It has the superiority of facilitating significant symptomatic resolution and reducing the post-operative complications.
