Abstract
in English, Italian

Objectives: To compare pre- and post-operative pure tone audiometric and impedance audiometric analysis following conventional and endoscopic microdebrider assisted adenoidectomy and compare the outcomes.

Methods: Patients diagnosed with chronic adenoiditis were divided in groups of 25 each. Patients in the first group underwent conventional curettage adenoidectomy, while those in second group underwent endoscopic microdebrider assisted adenoidectomy. Pre- and post-operative pure tone and impedance audiometry were performed for all patients and outcomes were compared.

Results: The endoscopic microdebrider assisted method resulted in significantly better outcomes compared to conventional curettage. Criteria such as hearing threshold (p value 0.004 at second follow-up), peak pressure (p value 0.045 at first follow-up) and tympanogram (p value 0.016) showed that the endoscopic method was better, while peak compliance (p value 0.340 at first follow-up) did not show any significant difference between groups.

Conclusions: The endoscopic microdebrider assisted method for adenoidectomy has a definite advantage of better visualisation resulting in better clearance of tissue, leading to enhanced middle ear function compared to conventional curettage.

Valutazione della funzione dell’orecchio medio dopo adenoidectomia convenzionale vs endoscopica con microdebrider.

Obiettivi: Confrontare i risultati dei test audiometrici tonali e di impedenzometria prima e dopo l’esecuzione di adenoidectomia convenzionale ed endoscopica con microdebrider.

Metodi: Cinquanta pazienti con diagnosi di ipertrofia adenoidea sono stati suddivisi in due gruppi di 25. Il primo gruppo è stato sottoposto ad adenoidectomia convenzionale, mentre nel secondo gruppo l’adenoidectomia è stata eseguita con microdebrider sotto visione endoscopica. Valutazioni audiologiche di audiometria tonale e impedenzometria sono state eseguite in tutti i pazienti prima e dopo l’intervento, e i risultati sono stati confrontati.

Risultati: L’adenoidectomia endoscopica ha mostrato risultati audiologici migliori con una differenza statisticamente significativa per quanto riguarda la soglia uditiva (p value 0,004 al secondo controllo), la pressione al picco (p value 0,045 al primo controllo), e il timpanogramma (p value 0,016), mentre la compliance al picco (p value 0,340 al primo controllo) non ha mostrato differenze tra i due gruppi.

Conclusioni: Rispetto all’adenoidectomia convenzionale, l’adenoidectomia endoscopica con microdebrider ha il vantaggio di una miglior visualizzazione, che determina una più completa rimozione del tessuto adenoideo e un miglioramento della funzionalità dell’orecchio medio.
