Objectives: To determine the rate of direct visibility of
incudostapedial joint during the middle ear operations in the Turkish
population and to assess the complications occurring during the
resection of chordal crest.
Methods: Operation records of 678 patients who underwent middle ear
surgery (tympanoplasty, stapes surgery, explorative tympanotomy) between
2001 and 2007 at Şişli Etfal Teaching and Research Hospital has been
investigated retrospectively. The rate of visibility of incudostapedial
joint with or without intervention to chordal crest has been determined
during these surgeries. Complications of surgeries at which chordal
crest excised have been assessed.
Results: Incudostapedial joint has been observed directly in 513
(75.6%) ears operated while it has become visible with the excision of
chordal crest in 165 (24.4%) ears. Of the 165 cases who underwent
chordal crest resection, 3 (1.8%) cases had chorda tympani detachment, 6
(3.6%) cases had transient taste disturbance, 2 (1.2%) cases had
perilymphatic leakage and one (0.6%) case had mild sensorineural hearing
loss.
Conclusion: The rate of direct visibility of incudostapedial joint
during the middle ear surgeries in Turkish population is very high.
Although the rate is low, resection of the chordal crest to make the
joint visible can cause some kind of complications. |
