Fractures with minor malocclusion readily correctable with maxillary disimpaction and manipulation, and not grossly mobile after repositioning may be treated closed.
Patients with malocclusion unable to have general anesthesia can be treated by application of arch bars and elastic traction.
A closed reduction of the midface may be part of an emergency treatment to reduce bleeding. Other options to control bleeding may include nasal packing or placement of a nasal balloon. If these methods fail, an invasive radiologist may be able to assist in the thrombosis of bleeding vessels.
2. Aftercare following closed treatment of Le Fort I and palatoalveolar fractures
Keeping the patient’s head in an upright position both preoperatively and postoperatively may significantly improve periorbital edema and pain.
The use of the following perioperative medication is controversial. There is little evidence to make strong recommendations for postoperative care.
No aspirin or nonsteroidal antiinflammatory drugs (NSAIDs) for 7 days
Analgesia as necessary
Antibiotics (many surgeons use perioperative antibiotics. There is no clear advantage of any one antibiotic, and the recommended duration of treatment is debatable.)
Nasal decongestant may be helpful for symptomatic improvement in some patients.
Steroids, in cases of severe orbital trauma, may help with postoperative edema. Some surgeons have noted increased complications with perioperative steroids.
Ophthalmic ointment should follow local and approved protocol. This is not generally required in case of periorbital edema. Some surgeons prefer it. Some ointments have been found to cause significant conjunctival irritation.
Regular perioral and oral wound care has to include disinfectant mouth rinse, lip care, etc.
Postoperative examination by an ophthalmologist may be requested. The following signs and symptoms are usually evaluated:
Vision (except for alveolar ridge fracture, palatal fracture)
Diplopia (except Le Fort I, alveolar ridge fracture, palatal fracture)
Globe position (except Le Fort I, alveolar ridge fracture, palatal fracture)
Perimetric examination (except Le Fort I, alveolar ridge fracture, palatal fracture)
If the patient complains of epiphora (tear overflow), the lacrimal duct must be checked.
Note: In case of postoperative double vision, ophthalmological assessment has to clarify the cause. Use of prism foils on existing glasses may be helpful as an early aid.
Postoperative imaging has to be performed within the first days after surgery. 3-D imaging (CT, cone beam) is recommended to assess complex fracture reductions. An exception may be made for centers capable of intraoperative imaging. Especially in fractures involving the alveolar area, orthopantomograms (OPG) are helpful.
Diet depends on the fracture pattern. Soft diet can be taken as tolerated until there has been adequate healing of the maxillary vestibular incision. Intranasal feeding may be considered in cases with oral bone exposure and soft-tissue defects. Patients in MMF will remain on a liquid diet until such time the MMF is released.
Clinical follow-up depends on the complexity of the surgery, and whether the patient has any postoperative problems.
With patients having fracture patterns including periorbital trauma, issues to consider are the following:
Other vision problems
Other issues to consider are:
Facial deformity (incl. asymmetry)
Sensory nerve compromise
Problems of scar formation
Issues to consider with Le Fort fractures, palatal fractures and alveolar ridge fractures include:
Problems of dentition and dental sensation
Problems of occlusion
Problems of the temporomandibular joint (TMJ), (lack of range of motion, pain)
The duration and/or use of MMF is controversial and highly dependent on the particular patient and complexity of the trauma. In some cases where long-term MMF may be recommended, the surgeon may choose to leave the patient out of MMF immediately postoperatively because of concerns of edema, postoperative sedation, and airway. In these cases the surgeon may choose to place the patient in MMF after these concerns have been resolved.
The need and duration of MMF is very much dependent on:
Type and stability of fixation (including palatal splints)
Coexistence of mandibular fractures
Patients with arch bars and/or intraoral incisions and/or wounds must be instructed in appropriate oral hygiene procedures. The presence of the arch bars or elastics makes this a more difficult procedure. A soft toothbrush (dipped in warm water to make it softer) should be used to clean the surfaces of the teeth and arch bars. Elastics are removed for oral hygiene procedures. Chlorhexidine oral rinses should be prescribed and used at least 3 times a day to help sanitize the mouth. For larger debris, a 1:1 mixture of hydrogen peroxide/chlorhexidine can be used. The bubbling action of the hydrogen peroxide helps remove debris. A Waterpik® is a very useful tool to help remove debris from the wires. If a Waterpik is used, care should be taken not to direct the jet stream directly over intraoral incisions as this may lead to wound dehiscence.
