Single stage maxillofacial reconstruction combined radical surgery for managing juvenile ossifying fibroma: A case report

Ossifying fibroma (OF) in craniofacial is a rare disease, benign, locally aggressive fibro-osseous tumor. The 2017 World Health Organization classifications divided OF into two types: OF of odontogenic origin and juvenile ossifying fibroma (JOF). Determining the right surgical treatment to reduce the postoperative recurrence rate is incredibly challenging. The author reports two cases of paranasal sinuses with disease onset progressed from pre-pubertal age. The first case is an example of a recurrent case after undergoing conservative surgery, and the second is a new one. All cases underwent radical surgery with subtotal maxillectomy and reconstructive surgery in one stage. After observing all patients until one year, there was no sign of recurrence through clinical and endoscopic examination. There are two types of surgery that compare in this case report: conservative surgery and radical surgery. Conservative surgical procedures include curettage, enucleation, or peripheral osteotomies. Several studies have shown high recurrence levels in OF patients when curettage or enucleation is performed; residue caused by incomplete excision is the most common reason that is easily caused by conservative surgery. Radical surgery such as open maxillectomy is a promising approach for degrading the level of recurrence. JOF, especially trabecular juvenile ossifying fibroma, shows a high recurrence percentage comparing other types. The first-choice management for treating OF was the surgical approach. Types of surgery depend on the disease's aggressiveness and morbidity. Radical surgery was proven better at decreasing recurrence level than conservative surgery.

Effect of two fascial incision options for access to the temporomandibular joint on facial nerve function: objective investigation

This study was performed to compare the effects on facial nerve (FN) function of the deep supra-temporalis muscle subfascial approach (DSFA) and traditional fascial approach (TFA) for access to the temporomandibular joint (TMJ), via qualitative and quantitative evaluations. Thirty patients requiring open TMJ surgery were randomly allocated to one of two groups: group A patients underwent the DSFA approach, while group B patients underwent the TFA approach. The TMJ was accessed via modified endaural incision with temporal extension. Clinical examinations, FN conduction tests, and electromyography (EMG) of the frontalis and orbicularis oculi muscles were used to assess FN function. A FN function deficit was noted in 50% of the whole sample population immediately after surgery, with no statistically significant difference between the groups (P = 0.082). Overall, 37.5% of the total study population experienced temporary loss of frontalis muscle activity, while zygomatic nerve injury was seen only in 25% of group A. Within 2-6 months, normal function returned in both groups. Nerve conduction studies showed no statistically significant difference between the groups in terms of nerve amplitude or latency after surgery. However, EMG of orbicularis oculi activity showed a significant difference between the groups after 6 months (P = 0.010). The results suggest that the traditional dissection approach is more protective of the FN, especially the zygomatic branch, than the deeper dissection technique.

Comparison radical surgery versus conservative surgery to decrease post-operative recurrence in ossifying fibroma: systematic review

Background: Ossifying fibroma in craniofacial is a rare disease, benign, locally aggressive fibro-osseous tumor. In the recent 2017 WHO classifications, ossifying fibroma divided into 2 type, ossifying fibroma of odontogenic origin and juvenile ossifying fibroma. Choosing the right treatment that can reduce the recurrence rate are particularly challenging. In this systematic review we try to analyse related study to determine the best treatment for ossifying fibroma. Aim: The aim of this review to evaluate best treatment option and analysed level of recurrence in each type of treatment. Method: Collected Juvenile Ossifying Fibroma (JOF) and Ossifying Fibroma (OF) related Article from four different database (PubMed, Scopus, Cochrane Library, and Proquest). Study selection was done by using PRISMA strategy. Result: Eight retrospective case series studies were analyzed. Recurrence rate after surgery was 15.3%, most frequent recurrence occurs in conservative surgery. Recurrence rate after conservative surgery was 19.7%, compared with radical surgery which relatively lower in percentage, with recurrence rate after surgery was 10.6%. Conclusion: Juvenile Ossifying Fibroma, especially Trabecular Juvenile Ossifying Fibroma (TrJOF), show high recurrence percentage comparing other type. The first-choice management for treating OF was surgical approach. Types of surgery choose to depend on the aggressiveness and morbidity of the disease. Radical surgery was proven better to decrease level of recurrence compared with conservative surgery.

Bone Grafts, Bone Substitutes, and Orthobiologics: Applications in Plastic Surgery

As reconstructive needs often extend past the soft tissue alone, a plastic surgeon must also be well versed in the methods of bony reconstruction. Understanding of the basic science of fracture healing and the biochemical mechanisms of the different bone grafts, bone substitutes, and orthobiologics is essential to selecting among the many different options available to the modern plastic surgeon. This review provides a broad overview of these different options and the specific applications for plastic surgeons based on anatomic location.

Clinicopathological Characteristics and Prognosis of Ossifying Fibroma in the Jaws of Children: A Retrospective Study

BACKGROUND: Ossifying fibroma in the jaws is a benign tumor and easily recurs in children, of which the treatment methods and prognosis still remain controversial. In this study, we aimed to review the clinicopathological characteristics, treatment, and prognosis of ossifying fibroma in the jaws of children, and offer recommendations for clinical decision-making. METHODS: A retrospective study was carried out on patients below the age of 18 years with ossifying fibroma in the jaws. Patients with complete clinical, pathological, and radiological records were included and followed-up. RESULTS: Sixty-three cases were collected with a preliminary search. After screening, fifty patients were included for general information analysis, of which forty-two patients were included in the recurrence analysis. Twelve patients showed a relapse, with a recurrence rate of 28.6% (12/42). The recurrence rates in cases with different surgical approaches and different X-ray boundaries were statistically different. Besides, twenty-three patients underwent reconstruction by free tissue grafting and the success rate was 96% (22/23). CONCLUSIONS: There was significant difference in the recurrence rates among different X-ray manifestations and surgical methods. An extended resection and reconstruction with free tissue grafting was a reliable method with a 96% success rate.

The use of the temporoparietal fascia flap in various clinical scenarios: A review of 71 cases

Objective:

This report details our experience with the use of the temporoparietal fascia flap in different scenarios of reconstruction and to discuss our technique of harvest, clinical applications, and review of literature of this versatile flap.

Materials and Methods:

A retrospective study of 82 cases of temporoparietal fascia flap in 71 patients, operated over a period of 10 years was conducted. Patients were grouped based on various clinical indications. The follow up period ranged from a minimum of 1 to a maximum of 10 years (Mean-four and a half years). All patients were analyzed for functional and aesthetic outcome using preoperative and postoperative photographs.

Results:

No significant complications were seen in our series. Only 2 out of 82 flaps had partial necrosis of flap (2.44%). Two patients who were operated for release of submucous fibrosis developed recurrence due to continued use of tobacco. The final outcome in one patient of ear reconstruction was unsatisfactory due to flap failure. The remaining patients had satisfactory functional and aesthetic outcomes (95.77%). None had other complications like temporal branch of facial nerve injury or alopecia along the scar line.

Conclusion:

The TPFF is one of the most reliable and versatile flap in the head and neck region. It can also be reliably used as free fascial flap. When its advantages are combined with the surgeon's resourcefulness, various defects can be successfully reconstructed using the temporoparietal facia flap with satisfactory aesthetic and functional outcome.

Reconstruction of mandibular defects

Defects requiring reconstruction in the mandible are commonly encountered and may result from resection of benign or malignant lesions, trauma, or osteoradionecrosis. Mandibular defects can be classified according to location and extent, as well as involvement of mucosa, skin, and tongue. Vascularized bone flaps, in general, provide the best functional and aesthetic outcome, with the fibula flap remaining the gold standard for mandible reconstruction. In this review, we discuss classification and approach to reconstruction of mandibular defects. We also elaborate upon four commonly used free osteocutaneous flaps, inclusive of fibula, iliac crest, scapula, and radial forearm. Finally, we discuss indications and use of osseointegrated implants as well as recent advances in mandibular reconstruction.

Bone grafts in craniofacial surgery

Reconstruction of cranial and maxillofacial defects is a challenging task. The standard reconstruction method has been bone grafting. In this review, we shall describe the biological principles of bone graft healing, as pertinent to craniofacial reconstruction. Different types and sources of bone grafts will be discussed, as well as new methods of bone defect reconstruction.

Temporomandibular joint reconstruction with costochondral graft using modified approach

12 patients presenting with long standing temporomandibular joint (TMJ) ankylosis were treated with a costochondral graft inserted through a modified approach. The age of the patients ranged from 5 to 17 years. A preauricular incision was made for resection of the ankylosed condyle. After release of the ankylosis the contralateral rib was harvested with costal cartilage. An intra-oral incision was made along the external oblique ridge to the mucobuccal fold and was used for resection of the coronoid process and insertion and fixation of the graft. The graft was fixed with a minimum of three titanium screws. The patients were instructed to start physiotherapy 1 week postoperatively and were followed up clinically and radiographically using 3D CT. Postoperative results were encouraging, the graft took well in all patients without postoperative infection or graft rejection. The graft was properly positioned in all cases. There were no visible scars as the preauricular scar is relatively hidden, no possibility of damaging the facial nerve or the marginal mandibular branch and shorter operating time.

Use of vascularised cartilage as an additional interposition in temporomandibular ankylosis surgery: Rationale, advantages and potential benefits

Context:

Surgery for the release of temporomandibular joint (TMJ) ankylosis is a commonly performed procedure. Various interposition materials have been tried with varying success rates. However, none of these procedures attempt to recreate the architecture of the joint as the glenoid surface is usually left raw.

Aims:

We aimed to use a vascularised cartilage flap and to line the raw surface of the bone to recreate the articular surface of the joint.

Settings and Design:

There is a rich blood supply in the region of the helical root, based on branches from the Superficial Temporal Artery (STA), which enables the harvest of vascularised cartilage from the helical root for use in the temporomandibular joint.

Materials and Methods:

Two cases, one adult and the other a child, of unilateral ankylosis were operated upon using this additional technique. The adult patient had a bony segment excised along with a vascularised cartilage flap for lining the glenoid. The child was managed with an interposition graft of costochondral cartilage following the release of the ankylosis, in addition to the vascularised cartilage flap for lining the glenoid.

Results:

The postoperative mouth opening was good in both the cases with significant reduction in pain. However, the long-term results of this procedure are yet to be ascertained.

Conclusions:

The vascularised cartilage flap as an additional interposition material in temporomandibular joint surgery enables early and painless mouth-opening with good short-term results. The potential applicability of this flap in various pathologies of the temporomandibular joint is enormous.
