ABSTRACT
Introduction: Adenoids together with palatine tonsils tubaltonsils and lingual tonsil form the inner Waldeyer’s ring andits enlargement depends on external factors such as allergy,immunosuppression, passive tobacco smoke but mainlychronic bacterial and viral infection. The study comparesthe effectiveness of certain factors in conventional curettageversus endoscopic adenoidectomy in a tertiary care centrein Trivandrum, Kerala, India. Study was done with theobjectives to study the perioperative collateral injury, presenceof residual adenoid tissue and recovery time in conventionalversus microdebrider assisted endoscopic adenoidectomy inchildren less than or equal to 12 years.Material and methods: An observational study was done ina group of 60 patients of age less than or equal to 12 yearswho satisfied the inclusion criteria who underwent treatmentin department of ENT in Sree Gokulam medical collegeduring a period of 2017 – 2018. Patients were grouped into 2groups of 30 each. Group A underwent conventional curettageand group B underwent microdebrider assisted endoscopicadenoidectomy. Patients were followed up 1 week and 2months following the procedure by post operative nasalendoscopy to assess collateral damage and residual adenoidtissue.Results: The residual tissue in conventional adenoidectomywas 20% and 20 – 50% in 2 cases and more than 50% in 4cases. This was the main cause of persistence of symptomsin conventional adenoidectomy. The mean recovery timewas 4.1 days in conventional and 3.2 days in endoscopicadenoidectomy. In conventional adenoidectomy 3 cases(10%) had collateral damage in which 2 cases had injury toeustacian tube orifice and 1 case had injury to torus tubaris.In the endoscopic microdebrider assisted surgery no collateraldamage was recorded.Conclusion: The study showed that the completeness ofdissection, collateral injury and recovery time was better inthe endoscopic adenoidectomy compared to conventionalcurettage.
