Abstract

Background: Genial tubercles (GT) show different patterns in their shapes and position. Aim: To evaluate the position and dimensions of the GT. Material and methods: 60 mandibles from the anatomy department of MVJ Medical College were studied. The morphology and measurements of GT were recorded. Results: Type I , type II patterns were noted in 23.33% and 35%, type III and type IV in 26.67 % and 13.33 %. GT was absent in 1.67% of the mandibles examined. The mean height and width of GT was 6.3 ± 2.9 mm and 5.6 ± 1.6 mm. Mean distance from superior genial tubercle to the apices of lower incisors was 15.4 ± 4.1mm. Mean distance from the menton to the upper and lower margins of superior genial tubercles were 14.6 ± 2.3 mm and 8.5 ± 3.3 mm. Conclusion: Genioglossus advancement is one of the popular procedure for the treatment of obstructive sleep apnoea(OSA). This procedure is usually performed with mandibular osteotomy and advancement of genial tubercle (GT). The present study could help the maxillo-facial surgeons in designing the location
