Objetive. To analyze characteristics, clinical evolution and surgical techniques of oroantral communication (OAC). Study Design. We included all patients operated at the University Central Hospital (Oviedo, Spain) between 1996 and 2007. The variables assessed were age, sex, medical history, OAC size, sinus disease, surgical technique, duration of hospitalization and post-surgical evolution. Results. We analyzed 12 patients (7 men and 5 women) with an average age of 47.5 years. The most frequent cause of oroantral communication was the extraction of the first upper molar. The average size of fistula was 0.9 cm. Buccal flap repair was used in 7 patients, palatal rotation-advancement flap in 4 patients and buccal fat pad in only one patient. Suture dehiscence was observed in one patient treated with a palatal flap, but no additional surgery was required. Three OAC recurred; all of them following a buccal flap procedure. All recurrences spontaneously closed between one and four months following the procedure. Conclusion. OACs are rare complications and treatment should be individualized to avoid further complications.

The use of pedicled buccal fat pad flap (BFP) has proved of value for the closure of oroantral and oronasal communications and is a well-established tool in oral and maxillofacial surgery. Otherwise, the perceived limitations of surgical therapy for bisphosphonate-related osteonecrosis of the jaws (BRONJ) have been widely discussed, and recommendations have largely been made to offer aggressive surgery only to stage 3 patients refractary to conservative management. Oroantral communication may be a common complication after sequestrectomy and bone debridement in upper maxillary BRONJ. We report a case series of stage 3 recalcitrant maxillary BRONJ surgically treated with extensive sequestrectomy and first reconstruction using pedicled BFP. All the cases presented an uneventful postoperative healing was uneventful without dehiscence, infection, necrosis or oroantral communication. We postulate that managing initially the site with BFP and primary closure may ensure a sufficient blood supply and adequate protection for an effective bone-healing response to occur. This technique may represent a mechanic protection and an abundant source of adipose-derived adult stem cells after debridement in upper maxillary BRONJ. We evaluate in this work results, advantages and indications of this technique. Key words: Buccal fat pad flap, bisphosphonate-related osteonecrosis of the jaws, oroantral communications, sequestrectomy.

The aim was to evaluate sentinel node detection capacity by means of a magnetic probe in 11 patients with oral squamous cell carcinoma at stages T1‐T2 received submucosal injections of a superparamagnetic iron oxide contrast agent (SPIO). A magnetic probe was used for sentinel node biopsy. The use of SPIO and magnetic probes in the early stages of oral cancer may offer an alternative to conventional radioisotope techniques and/or elective neck dissection.

Based on the present patient, it may be concluded that mandibular osteoma treatment by means of piezoelectric surgery makes precise exeresis possible with less affectation of the important surrounding structures such as the inferior alveolar nerve and the marginal mandibular branch of the facial nerve.

Satisfactory esthetic and functional results were achieved using three-dimensional digital technology for treatment planning and to fabricate a made-to-measure polyethylene prosthesis and surgical guide.
