No significant difference was seen between the underlay and over-underlay techniques with respect to graft uptake, re-perforation, retraction, graft lateralisation, Air-Bone Gap or Pure Tone Audiometry result.
All their cases had successful grafts (100%) and lateralisation of grafted drum did not occur.
78 and in this group 04 patients had graft failure and 02 cases presented with graft lateralisation.
Instead, lateralisation may have a genetic basis or alternatively may be influenced by factors in the early embryonic period," they wrote in their paper.
It was therefore likely that lateralisation did not originate in the brain.
The researchers wrote: "The early establishment of pre-natal behavioural lateralisation may have a potentially powerful role in the development of subsequent behavioural lateralisation and brain asymmetries.
Table 1: TOTAL NUMBER OF CASES MALES FEMALES TOTAL Vocal cord lateralisation 28 26 54 Endoscopic arytenoidectomy 19 14 33
RESULTS: Of 54 cases of vocal cord lateralisation 28 were successful, 26 cases reported with noisy breathing/aspiration and revision surgery was successful in only 5 patients.
DISCUSSION: The success rate of vocal cord lateralisation is 51% (57% males & 42% females).
This means that the most successful birds have a very strong cerebral lateralisation, which "is influenced by both genes and experience," according to Brown.
He and Magat found that the pattern of lateralisation, left or right bias, did not predict success as much as the strength of the particular bias did.
Our study shows that strong lateralisation improves problem-solving ability and foraging in birds, which is an evolutionary advantage," New Scientist quoted Brown as saying.
