<unk>  (GA) also known as genial tubercle<unk>  (GTA), is a surgical procedure or sleep surgery in which the base of the tongue is pulled forward, usually to increase airway size due to deformity or a sleep breathing disorder. This procedure is frequently performed with either uvulopalatopharyngoplasty or maxillomandibular<unk>  surgeries. Tongue muscles<unk> , geniohyoid and others) are attached to the lower jaw below the teeth. During a<unk>  procedure, a small window or bone cut is made in the front part of the lower jaw (mandible) at the level of the geniotubercle which is where the<unk>  muscle is attached. This piece of bone along with the attachment for the tongue (genial tubercle) is pulled forward and is subsequently secured to the lower jaw, usually with a single screw or with a plate(s) and screws. This procedure is often combined with other surgeries such as uvulopalatopharyngoplasties or maxillomandibular<unk>  surgeries. It is rare to have this procedure performed as the only surgical treatment for sleep apnea, as obstruction in sleep apnea is most often at multiple levels (nose, palate, tongue, etc.).
