RESUMO
This study aimed to assess efficacy of submucosal thulium laser turbinoplasty in children and to compare thulium laser turbinoplasty with partial inferior turbinectomy. This is a retrospective study over 10 years from 1 January 2009, conducted in a Pediatric Otorhinolaryngology Department in a university tertiary care center, including all the children who underwent thulium laser inferior turbinoplasty and partial inferior turbinectomy. The main outcome measures were the improvement in airflow using rhinomanometric cumulative flow at 150 Pa and then functional improvement using "OPERAS" score (nasal Obstruction, facial Pain, Epistaxis, Rhinorrhea, Anosmia, Sneezing). Eighty-six children underwent 47 submucosal thulium laser turbinoplasties and 48 partial turbinectomies. After submucosal thulium laser turbinoplasty, the cumulative flow at 150 Pa improved from 308.2 to 454.4 cm3 s-1 (p < 0.01) and the OPERAS score decrease was 1.5 point (p < 0.01). Daily use of intra nasal corticosteroid and antihistamine both decreased significantly. No local complications of this technique have been reported. Partial turbinectomies show a higher reduction of the OPERAS score and a better improvement of rhinomanometric parameters, but also a significantly higher complication rate. Submucosal thulium laser turbinoplasty is a good compromise between safety and efficacy, with substantial functional and rhinomanometric postoperative improvement.
