An oroantral fistula causes chronic sinusitis, whose signs and symptoms include facial pain, swelling, tenderness and nasal and oral discharge. The clinical diagnosis of oroantral fistula canbe confirmed by radiographic findings, and treated surgically by antrostomy alone or in combination with Caldwell-Luc's operation. The fistula is then repaired with mucosal flap or bone plug. We experienced one case of chronic sinusitis caused by oroantral fistula that was repaired with mucosal flaps (buccal and palatal region) with bone plug (taken from ilium) and produced good results. So we report it with the review of the literature.

The buccal fat pad is specialized fat tissue located anterior to the masseter muscle and deep to the buccinator muscle. Possessing a central body and four processes it provides separation allowing gliding motion between muscles, protects the neurovascular bundles from injuries, and maintains facial convexity. Because of its many advantageous functions, the use of the buccal fat pad during oral and maxillofacial procedures is promoted for the reconstruction of defects secondary to tumor resection, and those defects resulting from oroantral fistula caused by dento-alveolar surgery or trauma. We used the pedicled buccal fat pad in the reconstruction of intraoral defects such as oroantral fistula, maxillary posterior bone loss, or defects resulting from tumor resection. Epithelization of the fat tissue began 1 week after the surgery and demonstrated stable healing without complications over a long-term period. Thus, we highly recommend the use of this procedure.

Osteomyelitis caused by maxillary sinusitis is clinically rare. We report a case of a 43-year-old woman who presented with an oroantral fistula on the hard palate, originating from osteomyelitis complicated by maxillary sinusitis. To our knowledge, oroantral fistula on the hard palate caused by chronic rhinosinusitis is rare. Physical, radiological, and cytological findings revealed the clues suggesting osteomyelitis. We performed endoscopic sinus surgery for the sinus lesion and the fistula healed spontaneously after the procedure.

Recently, alloy dental implant is frequently performed in dentistry. The complications of a dental implant include maxillary sinusitis, oroantral fistula, displacement of implants and others. Maxillary sinusitis among these complications is one of the severe complications, which is being reported to occur rarely. The complications of dental implant are often accompanied by gingival swelling, pain, fistula and other symptoms, for which immediate therapeutic measures may be implemented. Nevertheless, as the authors encountered, overlooking secondary nasal symptoms of a dental implant may lead patients to rely merely on drug treatment without realizing the particular causes for such symptoms. The authors experienced a case with acute unilateral maxillary sinusitis developed after dental implant performed at the dental clinic, which was alleviated by performing endoscopic sinus surgery. Such complication has been rarely reported overseas, nor domestically. By reporting this case, we aimed to call attention to the complication of sinusitis and to take into consideration of implant displacement in suspicious cases of acute maxillary sinusitis.

fistula, oroantral fistula, traumatic deformities and others. The age of patients ranged from 7 to 72 years, with mean follow up period of 21.6 months. There were 9 complications, of which four were partial necrosis, there infections, one total necrosis and 1 speech problem. Except for total necrosis, most of the recipient sites healed uneventually without severe morbidity. We consider that a variety of intraoral local intraoral local flaps can be available for reconstruction of small or moderate large intraoral soft tissue defects.]]>

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.

To explore the efficacy and value of personalized surgical schemes in the repair of maxillary sinus perforation and maxillary sinus fistula based on the size of the maxillary sinus perforation and maxillary sinus fistula. A total of 28 patients with maxillary sinus perforation and maxillary sinus fistula who were admitted to the Department of Oral and Maxillofacial Surgery, Stomatology Hospital of Kunming Medical University from July 2017 to May 2020 were included to conduct a prospective case clinical study. After the inflammation in the maxillary sinus was controlled, a proper surgical repair method was selected according to the size of the perforation and fistula based on the double-layer closure technique. The diameter of the perforation and fistula was measured with the assistance of cone-beam CT. After that, the platelet rich fibrin (PRF) repair was performed on the perforation and fistula with 3 mm≤diameter<7 mm in size in 14 patients. The PRF repair and buccal flap repair were performed on the perforation and fistula with 7 mm ≤diameter<15 mm in size in 7 patients. The adjacent buccal pad repair, palatine flap repair, and buccal flap repair were performed on the perforation and fistula with 15 mm≤ diameter<25 mm in size in 4 patients. The nasolabial axial flap repair and nasolabial free flap repair were performed on the perforation and fistula with a diameter ≥25 mm in size in 3 patients. The medical follow-up was conducted in all patients in the 1st, 2nd, and 4th week after surgery, with an overall success rate reaching 96.4% (27/28) after the initial intervention. The relapse of disease occurred in one patient (4.6%) with diabetes and a smoking history in the 2nd week after surgery. Identifying a proper surgical repair method according to the size of the oral and maxillary sinus perforation and maxillary sinus fistula based on the double-layer closure technique can improve the one-time cure rate in these patients under the premise that the inflammation in the maxillary sinus can be controlled.
