Oro-antral communications may develop as a complication of dental extractions, but may also result from accidental or iatrogenic trauma, neoplasm or infection . An oroantral fistula which is smaller than 2 mm frequently closes spontaneously. A 28 years old healthy male reported to the outpatient department of hospital for evaluation of pus discharging fistula distal to left upper first molar. A surgery was planned for the removal of displaced root segments and closure of the fistula. A Caldwell luc approach was used to remove the roots and the closure of oro antral fistula was done by using double layer technique with buccal fat pad and a buccal advancement flap. The sutures were then placed. The treatment of oronatral fistula through the use of buccal advancement flap and buccal fat pad is a simple and complete method which enables several uses in most of cases. Keywords : Coroantral fistula Introduction : The oroantral fistula (OAF) is a Case Report : A 28 years old healthy male pathological communication between the oral reported to the outpatient department of hospital for cavity and the maxillary sinus; depending on the evaluation of pus discharging fistula distal to left location it can be classified as alveolo-sinusal, upper first molar. The patient gave history of palatal-sinusal and vestibulo-sinusal. 1 Oro-antral traumatic extraction of upper left second molar 2 communications may develop as a complication of months back. He had discomfort in the region of dental extractions, but may also result from the extraction socket. Soon after, expression of a accidental or iatrogenic trauma, neoplasm or yellowish foul smelling discharge followed from infection. 2,3 An oroantral fistula which is smaller the socket, the patient reported for the dental check than 2 mm frequently closes spontaneously. up .The patient reported that the crown was However, when the defect is bigger or when there fractured while extraction. The patient also is inflammation, maxillary sinus or periodontal reported of foul smelling discharge from nose region infection, such fistula demands surgical while drinking water. The intra oral examination treatment for its complete closing. 4 This article revealed that the left upper second molar was reports a case of a oro-antral fistula successfully absent. Purulent material from the fistula was treated with a double layer technique using buccal observed distal to left maxillary first molar. A fat pad and buccal advancement flap and removal provisional diagnosis of oro-antral fistula was of displaced roots of molar from the antrum. given based on the history and examination. 116 www.ijhbr.com ISSN: 2319-7072 International J. of Healthcare and Biomedical Research, Volume: 2, Issue: 3 , April 2014 , Pages 116-119 The patient was advised for a orthopantomograph with displacement of two roots into maxillary OPG and cone beam computed tomography CBCT. sinus. The radiographs revealed oro antral communication FIG 1- PREOPERATIVE A surgery was planned for the removal of displaced root segments and closure of the fistula. A Caldwell luc approach was used to remove the roots and the closure of oro antral fistula was done by using double layer technique with buccal fat pad and a buccal advancement flap. The sutures were then placed. FIG 2- SURGERY FOR CLOSURE OF FISTULA Routine postoperative instructions with prescription of antibiotics and analgesics were given to the patient. The patient was warned against blowing the nose for 2 weeks. The post operative CBCT showed maxillary antrum clear of the root stumps. 117 International J. of Healthcare and Biomedical Research, Volume: 2, Issue: 3 , April 2014 , Pages 116-119 FIG 3 –POSTOPERATIVE The patient was followed-up for duration of 2 months periodically at the regular intervals to evaluate for any postoperative complication. Complete epithelisation was observed after 6 weeks. No post operative complications were evident. I FIG 4-POSTOPERATIVE HEALING DISCUSSION buccal fat pad is an encapsulated, rounded, The primary closing of oro-antral fistulas in 48 biconvex specialized fatty tissue which is distinct hours presents a 90 to 95% success rate, and such from subcutaneous fatty tissues. It is located rate falls to 67% when the closing is secondary. 5,6 between the buccinator muscle medially, the Numerous surgical methods have been described anterior margin of the masseter muscle and the for treatment of oro antral fistulas, although only a mandibular ramus and zygomatic arch laterally few have been accepted in daily practice.

The advantages of pedicled buccal fat pad 117118 International J. of Healthcare and Biomedical Research, Volume: 2, Issue: 3 , April 2014 , Pages 116-119 (BFP) include ease of harvesting, simplicity, more stability, can be used to cover BFP and as versatility, low rate of complications, and quick additional tissue for closure where there is a surgical technique. The blood supply of the buccal deficient BFP for closure. fat pad is not affected due to its displacement, once CONCLUSION it is gripped and replaced between the flap and the The treatment of oronatral fistula through the use maxillary wall. It is worth noting that the use of of buccal advancement flap and buccal fat pad is a BFP with buccal advancement flap (combination simple and complete method which enables several technique) in the literature is scarce. 11,12 It provides uses in most of cases.
