Abstract
Levator glandulae thyroideae, an embryological remnant found in association with pyramidal lobe in the thyroid gland is often encountered during thyroidectomy. Complete removal of these structures will prevent the incidence of recurrence. In this context, we studied the use of a surgical loupe in increasing the identification rate of levator glandulae thyroideae. This cross-sectional study was conducted in the department of surgery in a tertiary care centre from February 2015 to July 2015 with data collected from randomly selected patients posted for thyroidectomy. Age, sex, presence of the pyramidal lobes and levator glandulae thyroideae were studied. Statistical analysis was done with R statistical programming software version 3.2.0. There were 45 patients in the study. The median age was 41 years (range 22-57). There were 9(20%) males and 36 (80%) females. Levator glandulae thyroideae was dissected out in 33(73.3%) of the patients. This was attached to pyramidal lobe in 31(93.94%)and only in 2(6.06)cases it arose from the isthmus. In patients with pyramidal lobe present,31(83.8%) 31(83.8% )patients had levator glandulae thyroideae and there was a statistically significant association between pyramidal lobe and levator glandulae thyroideae. This study showed that with the help of a surgical loupe, more than 73 percent of the levator glandulae thyroideae can be dissected out. Inclusion of a magnifying surgical loupe in the surgical armamentarium during routine thyroidectomy could potentially reduce the recurrence of goiter.
