"Does Maxillomandibular Fixation Affect Respiratory Function? A Systematic Review"

In an article published in the February 2022 issue of the Journal of Craniofacial Surgery, T Sampaio et al. conducted a grey literature and published literature database review to determine if maxillomandibular fixation impacts respiratory function. They reviewed studies that had the following parameters: forced vital capacity, forced expiratory volume in the first second, the ratio of these values, and the peak expiratory flow. These parameters had lowered values during maxillomandibular fixation, but returned to normal respiratory function after the removal of MMF.

The authors conclude that "maxillomandibular fixation temporarily affects respiratory function during use, but it is restored on removal, therefore not precluding its use on healthy patients who have good nasal breathing prior to the procedure. However, in patients suffering from some form of respiratory limitation or pulmonary disease, and also mouth breathers, maxillomandibular fixation should not be used so as to avoid more severe respiratory complications, underlining the importance of preoperative pulmonary evaluation."

Minne Ties Tip of the Month: Choosing the Correct Patient

It is important to carefully assess when Minne Ties are appropriate for patients. Minne Ties are an addition to a surgeon’s toolbox and not a complete replacement for other currently used MMF methods. When initially learning to use Minne Ties, select patients with good dentition and tight contact points. With experience, use broadens to patients with some missing dentition and/or gaps between some teeth. Using a full complement of Minne Ties (i.e. 6-8 Ties) or alternative application methods such as the Figure 8, may be helpful in these situations. Additionally, adequate dentition and good contact points are important consideration for closed treatment.


The History of Facial Surgery: René Le Fort

René Le Fort was a renowned surgeon in the late 19th and early 20th centuries most famous for his achievements in the classifications of midfacial fractures. Dr. Le Fort became a military surgeon after becoming the youngest doctor to receive an MD in France. Throughout his career he worked as a professor, at a tuberculosis sanatorium, and as a military surgeon in the First World War.

In 1901 René Le Fort published his famous treatise titled Étude expérimentale sur les fractures de la mâchoire supérieure. He described three types of midfacial fracture patterns: Le Fort 1 (horizontal), Le Fort 2 (pyramidal), and Le Fort 3 (transverse). The commonly told story suggests that Dr. Le Fort dropped cannon balls onto cadaver heads to create facial trauma, but he actually used a combination of clubs, kicks, throws, and a vice. He then boiled the heads to remove the soft tissue without disturbing the bones.
