The Immediate Effect of Power Assisted Endoscopic Adeno with Microdebrider on Eustachian Tube Function in Children

Al Hussien Awad Ali and Mostafa A Youssif

Objectives: To evaluate the effect of power assisted endoscopic adenoidectomy with Microdebrider on Eustachian tube function in the early postoperative period in children with adenoid hypertrophy and normal preoperative middle ear pressure.

Patients and Methods: Prospective study was conducted on 30 children with adenoid hypertrophy and normal preoperative tympanograms who underwent Power assisted endoscopic adenoidectomy with Microdebrider from April 2015 to February 2016. Tympanometry was done on the same day before operation, and repeated on the first, third and seventh day postoperatively.

Results: Thirty patients were included in the current study, 18 males and 12 females. The average age was 7.5 years. The middle ear pressure (MEP) of at least one ear was decreased on the first postoperative day in 12 (40%) patients and in 4 (13.3%) patients on the third postoperative day, and then returned to the normal preoperative MEP by the seventh postoperative day.

Conclusion: Immediate transient Eustachian dysfunction occurs in the early postoperative period in children after power assisted endoscopic adenoidectomy with Microdebrider, with early complete resolution. This transient Eustachian dysfunction may be due to oedema of nasopharyngeal mucosa, postoperative blood clots, or the very rarely unintentionally surgical trauma.
