ABSTRACT
OBJECTIVE@#This study aimed to investigate the application of acellular dermal matrix and acellular bone matrix in the management of oro-antral fistula.@*METHODS@#Nine patients with oro-antral fistula (with defect greater than 5 mm×5 mm) after maxillary cyst resection or maxillary molar extraction were selected. The defects were repaired by the simultaneous implantation of acellular dermal matrix and acellular bone matrix.@*RESULTS@#The incisions of nine patients were all primary healing. After 6 months of follow-up, the oro-antral communication healed well, and no symptom such as nasal congestion or runny nose was observed. The clinical and CT examinations confirmed wound healing.@*CONCLUSIONS@#The usage of acellular dermal matrix and acellular bone matrix is a reliable repairing method for ora-antral fistula.

Los quistes de retención mucosa y los mucoceles son las lesiones máscomunes de los senos paranasales. Éstos comparten características muysimilares y su diferencia estará determinada por su etiología. A diferencia del quiste de retención mucosa, cuyo comportamiento es mucho más sutil, el mucocele causa fenómenos infl amatorios locales, y algunas veces,reabsorción ósea de las estructuras adyacentes. El tratamiento será laenucleación quirúrgica. En el caso clínico que presentamos a continuación,se evidencia una lesión quística que se expone a través del alvéolo no cicatrizal de extracción traumática realizada semanas atrás, además se presenta la técnica que utilizamos para el cierre de fístula oroantral.
Mucus retention cysts and mucoceles are the most common lesions of the paranasal sinuses. They share very similar characteristics and the difference between them depends on their etiology. Unlike mucous reten-tion cysts, whose behavior is much more subtle, mucoceles cause local infl ammatory phenomena and sometimes bone resorption of adjacent structures. The treatment called for is surgical enucleation. The clinical case presented deals with a cystic lesion protruding through the non-cicatricial alveolus following a traumatic extraction performed weeks earlier. We also present the technique used to close the oroantral fi stula.

Sinus lifting was introduced for prosthetic reconstruction in 1960 decades by Boyne and is specifically used for implant surgery in maxillary posterior region with insufficient bony height and has been indicated for reconstruction of oro- antral and palato-alveolar cleft. We report that subtotal maxillectomy using sinus lifting and skin graft in mild maxillary cancer cases results in good prevention of oro-antral and oro-nasal fistula by preserving intact maxillary sinus mucosa and improves better functional outcome after maxillectomy.
