Objectives: The present study was designed to evaluate the outcome
of meatoplasty using Z-shaped incision with application of mitomycin C
as trial to enlarge the external auditory meatus of patients undergoing
modified radical mastoidectomy in comparison to classic meatoplasty
with application of mitomycin C.
Patients 61 Methods: The study included 40 patients; 25 males and
15 females with mean age of38.78.4 years. All patients underwent full
history taking, complete otorhtnolaryngological examination and CT scan
ning and then were randomly allocated into two equal groups (n=20) ac
cording to the procedure assigned: Classic meatoplasty (C group) and Zshaped
meatoplasty (Z group) using Z-shaped skin incision made along
the posterior and inferior concha! borders and extended along the posteri
or ear canal meatus. In both groups, mitomycin C, 0.4 mg/ml solution
was applied on a sponge to the edge of the remnants of concha! cartilage
for 5 minutes. Patients were examined bi-weekly till the ear was fully
healed Meatoplasty was assessed as regards the feasibility of easy ex
amination and debridement with the use of simple otologic tools and an
operating microscope. Both groups were compared as regards age, sex,
operative time and amount of intraoperative bleeding. |
