تهدف هذه الدراسة إلى تقييم فعالية الفبرين الغني بالصفيحات في إغلاق الاتصال الفموي الغاري و ذلك خلال شهرين من المتابعة السريرية و الشعاعية. بلغت عدد حالات البحث أحد عشر حالة جراحية أنجزت على الجنسين (45.5% ذكور ،54.5 إناث) ممن تعرضوا لانفتاح الجيب الفكي التالي لقلع الأسنان ، حيث تم الإغلاق باستخدام علقة الفبرين التي تم دكها مكان القلع السني الحاوي على الانفتاح و خياطة غشاء الفبرين إلى حواف اللثة فوقها. أظهرت النتائج نجاح الفبرين في إغلاق الانفتاح الفموي الغاري بنسبة 81.8 % مع اختلاطات تالية للعمل الجراحي بلغت وفق التالي: حدث الألم عند المرضى بنسبة 27.3 % ، التورم بنسبة 18.2 % و التفزر بنسبة 18.2 %. نستنتج أن الفبرين الغني بالصفيحات يتمكن عند استخدامه كغشاء و علقة معاً من إغلاق الانفتاحات التالية للقلع السني مع أعراض سريرية بسيطة و دون علامات شعاعية تدل على التهاب الجيب الفكي اللاحق.
The aim of the study was to evaluate the effectiveness of platelet-rich fibrin (PRF)
for closer of oroantral communication (OAC) during two months of clinical and
radiographical follow-up. Eleven patients of both sexes(45.5% males ,54.5% females)
included in this study who had (OAC) after dental extraction. The closer was done by
using fibrin clot which was plugged into the alveolar socket of the extraction site that
contains the communication, and then we sutured the fibrin membrane to the gingival
borders above it. The results revealed that (PRF) can close the oroantral communication
successfully in 81.8% of the sample with the following complications :pain 27.3% , edema
18.2% , dehiscence 18.2%. We conclude that platelet-rich fibrin can close oroantral
communication that results from dental extraction when it has been used as a clot and
membrane together with simple complicated subsequent clinical symptoms and without
radiographical signs of inflammation of the maxillary sinus.

Residual palatal fistulas are common after repair of palatal cleft
and tumar incision in palate and nasal cavity.
Repair of residual oronasal fistula is not always successful. Twolayer
closure techniques that close these fistulas with soft tissue
vestibular oro-nasal fistulas and alveolar clefts associate with cleft
lip and palate.
Sliding flaps are the most used flaps and often the sole method for
closure of vestibular oro-nasal fistulas and alveolar clefts. cheek
flap can be used instead of Sliding flaps.
