1/39. Experiences on the sequela of maxillary sinusitis following closure of the causative oro-antral fistula.

    After describing the method of treating sinusitis in established oro-antral fistulae, which consists of irrigation of the maxillary sinus, antibiotic therapy and closure of the fistula, our experience gained on 75 cases checked postoperatively is presented. We found that a radical operation of the sinus, even later, was not necessary in most cases (present investigation of our clinical material showed 97.3 per cent). The inflammatorily a altered mucosa recovers after the elimination of the causative factor, which in this case is the closure of the oro-antral fistula. These findings thus correlate with those made by Obwegeser a and Tschamer (1957) and by Killey and Kay (1967).

2/39. Team approach for closure of oroantral and oronasal fistulae.

    Oroantral and oronasal fistulas present with a broad range of causation, size, duration, and extent of infection involving the nose and paranasal sinuses. Accurate diagnosis of the extent of the disease with appropriate radiographic evaluation will guide the surgeon to select an approach that addresses all of the infected sites. When significant sinus disease is found, an endoscopic approach to restoring drainage in all of the involved sinuses can promote predictably successful closure of oroantral and oronasal fistulas. The multispecialty team approach to this disease, with the concomitant management of the sinusitis and fistula closure, is a significant advance in the successful management of this chronic condition.

3/39. Inadequate implant angulation resulting from oroantral fistula: case report.

    Successful implant surgery is largely dependent on good treatment planning and careful surgery. A complete treatment plan must encompass both surgical and prosthetic considerations for the implant restoration. Some compromised implants are restorable, and the result can be acceptable if they can be adjusted into a more ideal position. The goals of the segmental osteotomy are the preservation of a healthy dental unit, the creation of a more ideal environment for dental restoration and occlusal reconstruction, the optimization of cost effectiveness, and the minimization of edentulous space. The purpose of this study is to present the segmental maxillary osteotomy to reposition the alveolar segment with its implant that was in a highly compromised situation.

4/39. A modified technique of using the tongue tip for closure of large anterior palatal fistula.

    Anteriorly based dorsal tongue flaps are the most commonly used flaps for closure of difficult palatal fistulae. The author presents a patient in whom the palatal defect was thought to be too big to be closed by the standard tongue flap. The tongue tip was divided into equal dorsal and ventral flaps, and both flaps were used to reconstruct the palatal defect. Technical considerations, and advantages and disadvantages of the procedure are discussed.

5/39. Treatment of a persistent oro-antral fistula with a posteriorly based lateral tongue flap.

    Occasionally an oro-antral communication persists after vigorous standard therapy. This case report demonstrates the successful use of a posteriorly based lateral tongue flap in such a situation.

6/39. Use of the buccal fat pad in maxillary and sinus grafting of the severely atrophic maxilla preparatory to implant reconstruction of the partially or completely edentulous patient: technical note.

    PURPOSE: To examine the use of the buccal fat pad (BFP) for correction of maxillary osseous defects, preliminary to dental implant reconstructions, and to present patients in whom this technique was used. MATERIALS AND methods: The blood supply of the BFP was investigated with a special laser Doppler flowmetry fiberoptic probe in situ before herniation and after placement of the pedicled BFP over maxillary bone grafts. RESULTS: The possibility of using the BFP pedicle flap to provide an immediate blood supply to a recipient site was confirmed, as it promotes rapid neo-vascularization of the grafted material over which it is placed. No complications were seen in the present patients. DISCUSSION: The BFP has an additional protective function of providing for a multiple-layer wound closure over all types of maxillary bone grafts, thereby preventing graft exposure and enhancing success. CONCLUSIONS: With its high blood flow, the BFP may offer protection and early blood supply to maxillary and sinus bone grafts.

7/39. Bilateral oroantral fistulas following devitalization of teeth by arsenic trioxide: a case report.

    Although it is well known that prolonged application or leakage of arsenic trioxide can cause severe damage to the periodontal tissues, the substance is still used by some dentists. This paper describes a case of arsenical necrosis of the jaws affecting the right and the left side of the maxilla. As a result of leakage into the tissues of an arsenical paste from the pulp chamber of endodontically treated teeth, bilateral oroantral fistula (OAF) occurred. It is concluded that there is no justification, whatsoever, for the use of arsenic in modern dental practice. In the following case, buccal advancement flap and submucosal palatal island flap techniques were used for to close the OAF. The submucosal palatal island flap technique resulted in successful closure of the OAF.

8/39. Herniation of an antral polyp through an oroantral fistula.

    This paper reports a case of herniation of an antral polyp through an oroantral fistula, appearing as a polypoid lesion of the alveolar ridge. The patient was a 24-year-old female, and her upper molar had been extracted two months previously. The lesion was asymptomatic, and was a soft tissue mass, red in color and nontender to palpation, involving the alveolar ridge in the maxillary molar area. review of the literature yielded only a few other such cases.

9/39. Non-surgical management of an oro-antral fistula in a patient with hiv infection.

    BACKGROUND: The risk of post-extraction complications is higher in patients who are immunosuppressed compared to other patients with normal immune function. In addition, invasive dental procedures are more likely to have serious complications in these patients. This case report demonstrates an effective non-surgical procedure to treat an oro-antral fistula in an hiv-infected man. methods: The oro-antral fistula was de-epithelialized under local anaesthesia and the patient wore a surgical splint continuously, removing it only for cleaning, for an eight week period. chlorhexidine gel was regularly applied to the fitting surface of the splint and the oro-antral communication. The patient was reviewed on a regular basis. RESULTS: This procedure resulted in resolution of the patient's symptoms within two weeks. Complete healing of the oro-antral fistula was evident following eight weeks of wearing the surgical splint. CONCLUSIONS: This procedure provided an effective method of treating an oro-antral fistula in an immunocompromised patient without causing any detrimental effects to the patient's overall health. Adequate pre-surgical assessment of patients prior to extractions is important in all patients to help prevent the occurrence of such complications.

10/39. An unusual cause of oro-antral fistula.

    A case of oro-antral fistula associated with an apparent foreign body following antral packing for a zygomatic complex fracture 10 years previously is presented. This was treated by antral exploration, removal of the antral contents and repair of the fistula. The complications of antral packing for zygomatic and orbital floor fractures are reviewed and those situations where antral packing may be the treatment of choice are defined.
