Objective:
Voice alteration as a presenting symptom in cases with Chiari formation is analyzed, as well as outcome after atlantoaxial fixation.
Methods:
During the period January 2016 to June 2017, 25 cases of Chiari formation presented with associated or a major presenting symptom of voice or speech quality alteration related to inadequate breathing efforts. All patients underwent atlantoaxial fixation. No foramen magnum decompression was done.
Results:
In all patients, the voice quality and volume and breathing disturbances improved in the immediate postoperative period after recovering from anesthesia. During the period of follow-up that ranged from 12 to 25 months, all patients continued to improve in their speech function.
Conclusions:
Such critical symptoms of voice disturbance and inadequate breathing and the possibility of rapid postoperative recovery have not been recorded earlier in the literature.
