A retrospective study of 35 patients with oro-antral fistulas of more than 2 weeks duration is presented. Treatment results by using the Rehrmann plastic procedure, as well as complications and sequelae are described. The results of bacteriological examination in 15 patients with maxillary sinusitis in association with oro-antral fistulas are presented. The bacteriological findings suggest that broad spectrum antibiotics in certain conditions should be administered in cases of persisting oro-antral fistulas associated with maxillary sinusitis. The results of the present study show that the Rehrmann-operation proves satisfactory even in treatment-resistent cases.

Article Synopsis
  • Rhinocerebral mucormycosis (RCM) can lead to severe facial deformities, and the proposed technique aims to use existing dentures as templates for reconstructive surgery and temporary prosthetics.
  • A study conducted with 30 patients undergoing microvascular fibular flap reconstruction showed successful results, with only one flap failure that was later salvaged successfully.
  • The method offers a promising option for both cosmetic and functional restoration in young, healthy patients, enhancing both hard and soft tissue reconstruction along with dental restoration.

Odontogenic sinusitis (ODS) is more common than historically thought, representing 25% to 40% of all maxillary sinusitis. Due to a lack of widely accepted diagnostic criteria and a specific international diagnostic code, a true overall prevalence is unknown. ODS may be caused by either a multitude of infectious dental pathologies or complications after dental procedures.

Chronic odontogenic maxillary sinusitis (COMS), a prolonged inflammation of the maxillary sinus lasting over 12 weeks, is often a result of periapical lesions, marginal periodontitis, and complications like oro-antral communication (OAC) and fistula (OAF). OAC, commonly emerging post-teeth extraction in the lateral maxilla, lacks documented treatments using advanced platelet-rich fibrin (A-PRF). This study evaluates A-PRF's efficacy in treating COMS and immediately sealing extensive OAC.

Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tanta University, El-Giesh St, Tanta, Gharbia, Egypt.

Background: An oroantral fistula is a communication between the maxillary antrum and oral cavity. This pathological communication is formed mainly due to dental extraction of maxillary premolars and molars. Adequate management should include closing the oroantral fistula and eliminating sinus infections to prevent recurrence and sinusitis.
