ABSTRACT

Oroantral fistula (OAF), also termed oroantral communication, is an abnormal condition in which there is a communicating tract between the maxillary sinus and the oral cavity. The most common causes of this pathological communication are known to be dental implant surgery and extraction of posterior maxillary teeth. The purpose of this article is to describe OAF; introduce the approach algorithm for the treatment of OAF; and review the fundamental surgical techniques for fistula closure with their advantages and disadvantages. The author included a thorough review of the previous studies acquired from the PubMed database. Based on this review, this article presents cases of OAF patients treated with buccal flap, buccal fat pad (BFP), and palatal rotational flap techniques.

ABSTRACT

Here we report a case of penetrating neck injury to the posterior fossa that was shown, using high-resolution computed tomography (HRCT) and digital subtraction angiography (DSA), to involve no vascular injury. A 54-year-old man was brought to the emergency department after a penetrating injury to the left side of the posterior neck and occipital area with a knife. He was in an intoxicated state and could not communicate readily. On initial examination, his vital signs were stable and there was no active bleeding from the penetrating site. Because of concern about possible injury to adjacent vessels, we performed HRCT and DSA sequentially, and identified that the blade of the knife had just missed the arteriovenous structures in the neck and posterior fossa. The patient was then transferred to the operating room where the knife was gently removed. Further careful exploration was performed through the penetrating wound, and we confirmed that there were no major injuries to the vessels and neural structures. Postoperative computed tomography revealed that there was minimal hemorrhage in the left cerebellar hemisphere. The patient made a full recovery without any neurologic deficit. In this case, HRCT is a suitable tool for the initial overall evaluation. For the evaluation of vascular injury, DSA can be a specific and accurate tool. Mandatory exploration widely used for penetrating injuries. After careful preoperative evaluation and interpretation, simple withdrawal of material can be a choice of treatment.

ABSTRACT

PURPOSE: The objective of this study was to evaluate the efficacy of the subperiosteal tunneling technique with iliac block bone graft for bone augmentation in an edentulous alveolar ridge. PATIENTS AND METHODS: Total of 8 sites in 7 patients were included in this study. The bone height was evaluated by CBCT preoperatively and 4 months after operation. Total of 11 implants were inserted and evaluated clinically and radiographically. RESULTS: Mean value of the increased bone height was 6.29 mm and no implant failure was observed. There were no complications such as soft tissue dehiscence, exposure of the grafted bone and infection. CONCLUSION: We have achieved excellent clinical outcomes by this technique, so we concluded that it is useful for augmentation of severely deficient alveolar ridge.
