RESUMEN
OBJECTIVE To investigate the efficacy of coblation in upper airway obstruction patients. METHODS Coblation Channeling was used in 814 obstructed nasal airway patients.Soft palate coblation with or without tonsil treatment was applied in 67 adult OSAHS patients.Coblation tonsillectomy or tonsillotomy with adenoidectomy was performed in 68 pediatric OSAHS patients.RESULTS For obstructed nasal airway patients,VAS scores of 720 (88.45 %) patients were 0 to 1 after one time treatment.Thirty-five (4.3 %) patients had second treatment,and then VAS scores dropped to 0 to 1.VAS scores of 59 (7.25 %) patients kept more than 5.For adult OSAHS patients,3 (4.5 %) patients were cured,38 (56.7 %) patients were improved, 19 (28 %) patients were effective and 7 patients were not improved.For pediatric OSAHS patient s,58 (85.29 %) patients' symptoms,such as snoring,breath difficulty, mouth breathing,or pharyngeal obstruction,were relieved and 10 (14.71%) patients' symptoms were improved. CONCLUSION Coblation is widely used in ENT patients with good results.Its advantages include easy to use, minimal invasive,safe,and much less pain.It is specially suitable for pediatric OSAHS patients.
