The objective was to determine the incidence of exposure of the lingual branch of the glossopharyngeal nerve during tonsillectomy with a retrospective review of surgical findings in 138 children who underwent total tonsillectomy at a tertiary medical center. Age, sex, surgical indication, tonsil size, congenital abnormalities, operative time, and surgical findings indicating the presence or absence of the glossopharyngeal nerve in the tonsillar fossa were recorded. Statistical analysis was performed with z test, t test, and Fisher's exact test. Thirty-seven nerves were observed in 28 patients, with preponderance for the left fossa (24 of 37 vs 13 of 37; P = .01). In a comparison of children with and without exposed nerves, there was no statistically significant difference in mean age (6.89 vs 7.08; P = .84), proportion of males (14 of 28 vs 54 of 110; P = 1), or proportion of 3 to 4+ tonsils (20 of 28 vs 73 of 110; P = .66). In approximately 20% of children undergoing tonsillectomy, the lateral pharyngeal musculature incompletely protected the lingual branch of the glossopharyngeal nerve from the tonsil capsule.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 December 2015.
All research outputs
#24,641,809
of 27,380,387 outputs
Outputs from Otolaryngology–Head and Neck Surgery
#4,016
of 4,662 outputs
Outputs of similar age
#345,863
of 401,526 outputs
Outputs of similar age from Otolaryngology–Head and Neck Surgery
#38
of 61 outputs
Altmetric has tracked 27,380,387 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,662 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.9. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 401,526 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 61 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
