“…A specially designed trephine system for genial bone advancement with a 78 % chance of capturing the geniohyoid was introduced (Hennessee & Miller, 2005). Generally, advancement of the geniohyoid and the anterior belly of the digastric muscle can produce the greatest amount of hyoid bone advancement (Kutzner et al, 2017). Several modifications have been reported for more accurate and reliable positioning (Merrick et al, 2007).…”

The geniohyoid muscle is one of the suprahyoid muslces, and arises from the inferior mental spine and inserts into the hyoid bone. The muscle is a narrow paired one and its main action is pulling the hyoid upward and forward. Its function is very important in deglutition as well as respiration. Therefore, this muscle has been extensively researched, especially in the context of dysphagia and sleep apnea. This review deals with the general anatomic features, main functions, and abnormal states of the geniohyoid muscle, and the clinical implications of these.

“…Multiple variations in the pattern of the digastric have been reported in the literature . There is a paucity of understanding regarding the function and structural importance of the geniohyoid and digastric muscles in their relation to tongue position, hyoid suspension, and airway dilation …”

“…Further study is also needed to determine the clinical resultant effects in patients with OSA of the genioglossus, geniohyoid, and digastric muscles, in isolation and in combination, on the upper‐airway caliber and hyoid position. We have previously performed a preliminary study of these effects in cadavers . Additionally, we are uncertain about the percentage of these dense muscle attachments to the anterior mandible that needs to be captured to advance the muscle a clinically relevant distance.…”

“…We also describe the poorly studied digastric muscle (another hyoid suspension muscle) to present a more complete anatomic understanding of the muscles that attach to the anterior mandible and may therefore be involved in osteotomy consideration in OSA “genioglossal” advancement. The role of the geniohyoid and digastric muscles in supine airway patency has recently been studied and found to be contributory in regard to their contribution to hyoid suspension . This study helps highlight the importance of the anatomic attachments and function of these muscles when expecting airway diameter opening and clinical improvement in sleep‐study parameters resulting from surgery to these targeted anatomic sites.…”

Objectives/Hypothesis Genioglossus advancement is performed in select patients with obstructive sleep apnea. Surgical techniques attempt to capture the genial tubercle of the mandible; however, measurements of the genioglossus, geniohyoid, and digastric muscles are poorly delineated. This investigation is the largest anatomic study exploring the muscles of genial advancement surgery and the first to quantitatively characterize muscular attachments relative to the tubercle, providing new insights from an anatomic perspective on optimizing muscular advancement. Study Design Cadaveric study. Methods Fifty‐three fresh cadaveric mandibles underwent dissection of the genial tubercle and genioglossus, geniohyoid, and digastric muscles. Results Genial tubercle, geniohyoid, and genioglossus mean height was 7.78 mm, 5.15 mm, and 6.11 mm, respectively. On average, the geniohyoid began 4.88 mm and ended 10.03 mm from the inferior border of the mandible; the genioglossus 11.91 mm and 18.01 mm, similarly. Intermuscular distance, if present, was 2.67 mm; the muscles overlapped in 28% of cadavers. The combined vertical height of the muscles at their mandibular attachment was 13.94 mm, significantly differing from the height of the genial tubercle. The left and right lateral insertion of the digastric muscles was 19.34 mm and 19.31 mm, respectively, from midline. Conclusions The variable range of muscle attachments suggests that genioglossal and geniohyoid attachments extend beyond the genial tubercle and may not originate concentrically from the tubercle, but overlap and lie in very close proximity. Mandibular anterior muscle attachments require anatomic accuracy and an effective operative evaluation of advancement before reproducible, clinically effective osteotomies can be recommended.

“…(4,5) The treatment proposed for OSAS is genioplasty, box osteotomy, mandibualr trapezoid osteotomy, circular osteotomy and mortised genioplasty. (6) During the procedure of genioglossus advancement; care should be taken to identify the bone segment attached to genioglossus muscle to avoid complications such as devitalisation of the incisor roots, mandibualr fracture and incomplete incorporation of genioglossus muscle hence the location of the genial tubercle plays an important role. In the study done by Yin SK et al he correlated the CT measurements and anatomical measurements of the genial tubercle in Chinese population.…”

Introduction: CBCT uses have been expanded in many field of medical sciences. In the same way, it can be used to assess the position and anatomy of the genial tubercle during the management of OSA. The present study was planned to assess the utility and accuracy of the 3 D cone beam CT in locating the exact anatomical position of genial tubercle in the human skull. Materials and Method: For the present study, 20 adult human cadaver head were randomly selected. All the cadaver underwent radiographic imaging with the cone beam CT. Based on the radiographic measurements, genial tubercle height, genial tubercle width, mandibualr height, distance from inferior border of mandible to genial tubercle and lastly mandibualr thickness were recorded. Results: A total of 20 cadavers were obtained from the department of anatomy. We observed that there were difference in the measurements obtained from CBCT to that of calliper but however when the statistics were applied this difference was not found to be significant. Discussion & Conclusion: No significant difference was seen between the two study group measurements cadaver dissections versus CBCT measurements. This radiographic technique may prove useful in preoperative planning for the mandibular osteotomy in genioglossus advancement procedures. In addition, this technique may allow for preparation of a pre-operative template to guide the surgeon. Future research will focus on the development of a simple surgical template to locate the genial tubercle accurately.
