Various methods have been described in literature for closure of the ora antral communications. The use of buccal fat is an alternative primarily because it is easy technique, minimal complications and morbidity for the patient. Authors present a challenging clinical case of closure of oro antral communication once the patient is a smoker and has had a fistula formation with purulent drainage.


Buccal pad fat; Pedicled graft; Oroantral communication; Buccal flap; Maxillary sinus


Buccal fat pad in recent years has become a well-accepted graft for covering intraoral defects [1]. This structure is also known by the eponym Bichat, since it was the french anatomist to discover this tissue in 1801 [1,2].

The buccal fat pad is a supple and lobulated mass, easily accessible and mobilized [3], located between the buccinator muscle and the mandibular ramus, separating the masticatory muscles from each other and often considered to be a nuisance when encountered in intra-oral procedures such as facial bone osteotomies, elevation of buccal flap or procedure on Stenson’s duct [1].

Egyedi [4] was the first to describe the use of Bichat fat pad with surgical description for closure of oro antral communications. This type of complication is quite usual and described in the clinical literature after the extraction of maxillary posterior teeth, especially in the presence pneumatization of the maxillary sinus [5,6].

Authors aimed to describe a case of closure of oro antral communication with challenging clinical frame, since the patient is smoker two-month latency time of the buco sinus fistula.

Case Report

A 47-year-old woman was referred to the dental clinic of Araçatuba Dental School complaining of severe headaches, especially when waking up, and development of sinusitis with an unpleasant taste in the mouth two months ago. The patient is a smoker, without any disease or allergy. She has reported all laboratory tests within normal limits, including periodic visits to the cardiologist and this case has already been evaluated by the otolaryngologist.

Intraoral physical examination has shown lack of healing of the socket corresponding to the tooth 26, with the presence of chronic purulent secretion in alveolar extraction. For purposes of evidence, the Valsalva test was performed, which was positive, therefore confirming the clinical diagnosis of oro antral communication. Immediately a panoramic radiograph was performed, which noted the absence of bone continuity on the floor of the maxillary sinus (Figures 1 and 2).

Figure 2: Preoperative panoramic radiograph.

Possible forms of treatment were exposed to the patient, always warning of the risk of failure, regardless of the therapeutic approach chosen, because it is a heavy smoker patient with presence of fully formed fistula, and sinusitis.

After administration of local anesthesia with articaine hydrochloride 4% with 1:100.000 epinephrine, the fistula was removed through an incision skirting corresponding to the tooth socket 26. After extensive washing of the area with 0.9% saline solution, then two relaxing incisions were made, an earlier and a more posterior to the region. Preceding the detachment, held several incisions into the periosteum and muscle layer in order to expose the fat pad of Bichat. Taken exposure, the tissue was pulled carefully with forceps dietrich until fully rested and covering the defect without tension. The buccal fat pad was sutured with 4-0 Vycril and retail was sutured with 4-0 Vycril and some points were given with 5-0 nylon (Figures 3 and 4).

After surgery, Antibiotic therapy with 400 mg metronidazole associated with 500 mg amoxicillin was prescribed for the patient 3 times a day for 15 days.

The post-operative instructions were to avoid blowing your nose, sneezing open mouth, sucking as avoid using straws and smoking, which were light and puffs fewer cigarettes per day. Moreover, continued use has been prescribed antibiotics and 750 mg of paracetamol 6 in 6 hours for two days and 100 mg of nimesulide 12 in 12 hours for 4 days.

Periodic visits were scheduled for 1 year and at the end we can infer the success of treatment (Figures 5 and 6), with total closure of oro antral fistula, with reported total cure of headache with sinusitis treatment together with an otolaryngologist.

Oro antral communication is an unnatural communication between the oral cavity and maxillary sinus and when it fails to close spontaneously, it remains patent and is epithelialized so that oro-antral fistula develops [7], as occurred in the case presented.

Surgical closure of an antral perforation is indicated if the opening is greater than 4-5 mm at the time of injury, if a sinus disease is present whatever the size of the opening, and if the communication is persistent [8]. As presented in this case, since the formation of the fistula was confirmed by the latency and chronicity of constant communication with purulent debt, beyond the patient’s pain complaints.

Numerous surgical techniques have been described in the literature, mostly based on mobilizing the tissue and advancing the resultant flap into the defect [7]. Techniques, from soft tissue-only closure to the use of composite closures involving alloplastic materials such as gold, acrylic, or bone grafts, have described. Soft tissue-only flaps include the buccal advancement flap, buccal fat pad flap, a combination of the buccal fat pad and advancement flap, the buccinators myomucosal flap, and the vascularized palatal island flap [5]. The authors decided to use the Bichat fat pad because of its reliability, ease of harvest, low complication rate, rich blood supply, simple procedure, and minimal discomfort to patient [1] in association an advancement flap.

The main disadvantage observed in this form of treatment is reported by the event displaying loss of the oral vestibule, wherein the patient will need to undergo sulcoplasty technique. However, because of the initial clinical status of the patient, this disadvantage becomes easily minimized for the restoration of homeostatic balance oro antral. Amazingly, this technique also improves the physiologic functions of the cheek, for example, suppleness and elasticity [3].

Therefore, as observed in the clinical case, there is the possibility of obtaining successful use of fatty body for closing oro antral fistula, even the most unfavorable ones.


The use of pedicle of the buccal fat pad for reconstruction of defects including oro antral communications is already more than consolidated in the literature, being easy to perform and convenient for both patients and for the operator. Furthermore, it’s located in the same surgical field as the defect to cover, therefor diminishing the risk of infection [1,3].
