Results and Analysis
This cross sectional prospective study was conducted from May 2012 to June 2014 (25 months). A total of 76 neck dissections were done for 64 patients who were included in this study.
Demographic Distribution
1.Age Distribution: The mean age of the study population was 42.4 years (10 years-78 years) 39 (61%) patients were less than 45 years of age and 25 (39%) were more than 45 years.
2.Gender: Of the 64 patients, there were 21 males and 43 females. Male-to-female ratio was 1:2. The mean age among males was 44.6 years and among females it was 41.4 years.
Operations Performed
A total of 76 neck dissections were performed for 64 patients.
Out of the 64 patients, 6 had undergone thyroidectomy with CCD previously and these patients underwent MRND alone. Of these, 2 underwent bilateral MRND and 4 underwent unilateral MRND.

3.Histopathological sub-types
The most commonly encountered sub-type of tumor was the conventional type (72.4%) of PTC, followed by the follicular type (25.8%). Other sub-types of PTC were very rare (only one case).
Frequency of involvement of cervical lymph node levels
Out of the 76 neck dissections, cervical metastasis was present in 55 (72.3%). And out of 51 lateral dissections, multilevel involvement (>1 lateral level involved) was seen in 40 (78.5%). Following table shows the frequency of LNM at various lymph node levels.

Level VI was observed to be the most commonly involved, followed by level IV, level III and level IIa. Involvement of level IIb and V was uncommon.
Skip Metastasis
Out of the 76 Neck Dissectionss that were performed, skip metastasis was seen in 10 cases (13.2%). The most frequently involved lateral levels in this group were level III (8/10) and level IV
