This retrospective study was performed to analyze the frequency and patterns of skeletal metastasis in HNSCC. Materials and Methods : We analyzed records of 8326 HNSCC patients attending our oncology outpatient department from January 2000 to December 2013. All statistical calculations were performed using MedCalc software for windows, version 12.5.0 (Osterd, Belgium). Results : Bone metastasis was found in 25 patients (0.3% of total HNSCC patients, nasopharynx excluded). 10 patients (0.66%) of carcinoma tonsil had skeletal metastasis. The patients of younger age groups had higher frequency of bone metastasis; 1.56% patients of age group 20-29 years while 0.26% patients of 60-69 years age group had skeletal metastasis (P < 0.001). However, no patient of >70 years age was found to have bone metastasis. Most common site of metastasis was spine (56%) followed by pelvis (32%). Isolated involvement of a single bony
