Bony palatal necrosis in a diabetic patient secondary to palatal rotational flap

The use of buccal fat pad free graft in closure of soft-tissue defects and dehiscence in the hard palate

Introduction:

The integrity of the palatal mucosa can be lost due to congenital, pathological, and iatrogenic conditions. Various surgical techniques have been suggested for the closure of palatal defects. The aim of the current study is to present the free buccal fat pad graft as a novel technique to repair the soft-tissue defects at the palate.

Patients and Methods:

During a 2-year period, the free fat tissue graft harvested from the buccal fat pad (BFP) (FBFG) and used to reconstruct five soft-tissue defects of the palate in five patients (2 women, 3 men; mean age, 34 years; range, 22–58 years). In two patients, the palatal defect size was 2–3 cm and resulted from the resection of pleomorphic adenoma. In two other patients, the defect was due to odontogenic lesion, and in the last patient, the etiology was an iatrogenic dehiscence during maxillary segmentation surgery. Patients were examined every 2 weeks in the first 3 months and thereafter every 3 months.

Results:

Five patients were treated with FBFG to reconstruct palatal defects and were followed up for 6–24 months. The healing process of the BFP and the recipient sites were uneventful, with minimal morbidity. At 3 months after the surgery, there was complete epithelialization of the graft at the recipient sites.

Conclusions:

Harvesting of FBFG is a simple procedure with minor complications; manipulation and handling the graft are easy. The use of FBFG in reconstruction of small and medium palatal defects is encouraging with excellent clinical outcomes.

Closure of oroantral fistula using titanium plate with transalveolar wiring

BACKGROUND

Alloplastic materials such as tantalum, gold plates and foils, hydroxyapatite blocks have been used for closure of oroantral fistula (OAF). However, these materials are not widely accepted in routine surgical closure of OAF due to cost, difficult handling, increased rate of infection, and exfoliation.

PURPOSE

To overcome the above drawbacks this study aimed to use titanium plates (0.3 mm) with transalveolar wiring fixation for closure of OAF.

PATIENTS AND METHODS

Ten patients with OAFs who consented to undergo this trial were selected and treated under an outpatient basis in the Oral Surgery Department, Faculty of Dentistry, Mansoura University, Egypt.

RESULTS

All OAFs were successfully treated with no eventful complications.

CONCLUSION

This study concludes that titanium plates with transalveolar wiring fixation is an excellent technique for closure of OAF. The high success rate with this technique warrants its use for closure of OAF.

Bisphosphonate Associated Osteonecrosis of the Jaw

In 2003, the first reports describing osteonecrosis of the jaw (ONJ) in patients receiving bisphosphonates (BP) were published. These cases occurred in patients with cancer receiving high-dose intravenous BP; however, 5% of the cases were in patients with osteoporosis receiving low-dose bisphosphonate therapy. We present the results of a systematic review of the incidence, risk factors, diagnosis, prevention, and treatment of BP associated ONJ. We conducted a comprehensive literature search for relevant studies on BP associated ONJ in oncology and osteoporosis patients published before February 2008.All selected relevant articles were sorted by area of focus. Data for each area were abstracted by 2 independent reviewers. The results showed that the diagnosis is made clinically. Prospective data evaluating the incidence and etiologic factors are very limited. In oncology patients receiving high-dose intravenous BP, ONJ appears to be dependent on the dose and duration of therapy, with an estimated incidence of 1%–12% at 36 months of exposure. In osteoporosis patients, it is rare, with an estimated incidence < 1 case per 100,000 person-years of exposure. The incidence of ONJ in the general population is not known. Currently, there is insufficient evidence to confirm a causal link between low-dose BP use in the osteoporosis patient population and ONJ. We concluded BP associated ONJ is associated with high-dose BP therapy primarily in the oncology patient population. Prevention and treatment strategies are currently based on expert opinion and focus on maintaining good oral hygiene and conservative surgical intervention.
