NCT07527260

Brief Summary

This study aims to evaluate the effects of conservative management versus surgical intervention (adenoidectomy alone or adenotonsillectomy) on symptoms and local IgE levels in children with allergic rhinitis (AR) accompanied with adenotonsillar hypertrophy. The primary objectives include the impact of conservative management and surgical interventions on AR symptoms and local IgE levels. The second outcomes include serum IgE levels, inflammatory cell profiles within the nasal mucosa, and postoperative complications.

Outcome Measures

Primary Outcomes (2)

  • Symptom scores

    Record self-assessed AR symptom scores including nasal congestion, runny nose, nasal itching, sneezing, itching and burning eyes, tearing and watering eyes, and eye redness. Each symptom was scored from 0 to 3 (0, no symptom; 1, mild symptom; 2, moderate symptom; and 3, severe symptom)

    Surgery Group: at baseline (Pre-surgery) and at 1, 3, and 6 months post-surgery; Medication Group: at baseline (Pre-treatment ) and at 1, 3, and 6 months post-treatment initiation.

  • Allergen-Specific IgE Levels in Nasal Cavity

    Measures the change in allergen-specific IgE (sIgE) levels in nasal cavity to evaluate the regulation of local allergic responses. * For the Surgery Group: Samples (nasal mucosa samples via endoscopic biopsy, nasopharyngeal swab samples) are collected before surgery (baseline) and at 1, 3, 6 months after surgery. * For the Medication Group: Samples are collected before medication initiation (baseline) and at 1, 3, 6 months after medication initiation. sIgE levels are detected using immunoassay techniques (e.g., ELISA). Results are reported as standardized concentration units (e.g., kU/L).

    Surgery Group: at baseline (Pre-surgery) and at 1, 3, and 6 months post-surgery; Medication Group: at baseline (Pre-treatment ) and at 1, 3, and 6 months post-treatment initiation.

Secondary Outcomes (5)

  • Serum IgE Levels

    Surgery Group: at baseline (Pre-surgery) and at 1, 3, and 6 months post-surgery; Medication Group: at baseline (Pre-treatment ) and at 1, 3, and 6 months post-treatment initiation.

  • Numbers and Proportions of Inflammatory cells in Nasal Cavity

    Surgery Group: at baseline (Pre-surgery) and at 1, 3, and 6 months post-surgery; Medication Group: at baseline (Pre-treatment ) and at 1, 3, and 6 months post-treatment initiation.

  • Nasal Endoscopy Scores

    Surgery Group: at baseline (Pre-surgery) and at 1, 3, and 6 months post-surgery; Medication Group: at baseline (Pre-treatment ) and at 1, 3, and 6 months post-treatment initiation.

  • Inflammatory Cytokine Levels in Nasal Secretions

    Surgery Group: at baseline (Pre-surgery) and at 1, 3, and 6 months post-surgery; Medication Group: at baseline (Pre-treatment ) and at 1, 3, and 6 months post-treatment initiation.

  • Surgical Complications

    Within 6 months after surgery.

AdenoidectomyPROCEDURE

Low-temperature plasma adenoid ablation is a minimally invasive procedure performed under general anesthesia. After induction, the nose and face are disinfected and draped in the usual manner; a Davis mouth-gag is inserted and the soft palate is retracted with two fine suction catheters. The surgeon holds a disposable low-temperature plasma wand in the right hand and a 70° nasopharyngoscope in the left, then systematically ablates the hypertrophic adenoid tissue from inferior to superior and from center to periphery; the entire ablation takes approximately 10 min. Hemostasis is obtained with targeted cautery, the scope is withdrawn, and the operation is concluded. The technique produces minimal trauma, little bleeding, and rapid recovery. Medical therapy with daily administration of NASONEX nasal spray (50 µg per nostril, once every morning). Treatment was maintained for four weeks, with scheduled follow-up visits to evaluate efficacy and monitor adverse reactions.

Adenoidectomy and drug therapy

Low-temperature plasma adenoidectomy begins with general anesthesia for the patient. The surgeon holds a disposable low-temperature plasma electrode in the right hand and a 70° nasal endoscope in the left hand (inserted through the mouth), and gradually ablates the hypertrophic adenoidal tissue from bottom to top and from the center to the periphery. The entire procedure takes approximately 10 minutes. After ablation is completed, electrocoagulation is used for local hemostasis. Medical therapy with daily administration of NASONEX nasal spray (50 µg per nostril, once every morning). Treatment was maintained for four weeks, with scheduled follow-up visits to evaluate efficacy and monitor adverse reactions.
