Abstract

Objective.

This retrospective study aimed to assess the frequency and distribution of incidents encountered during the perioperative period of maxillary distraction with internal devices. The perioperative period was defined as the period between device placement and removal.

Study Design.

Records of 20 patients treated during 2004-2011 with internal maxillary distraction osteogenesis were examined. Incidents were registered in terms of severity and need of intervention.

Results.

Eighty percent of the patients experienced minor incidents, of which the most frequent were pain during activation and infections; 80% of these experienced ≥1 hard and soft tissue–related incidents, and 20% ≥1 device-related incidents. All incidents were solved with minimal or no intervention.

Conclusions.

Maxillary distraction using internal devices is a safe treatment with only minor incidents in the perioperative period. Preoperative planning and good cooperation are essential for preventing postoperative incidents. Prophylactic antibiotic treatment during the distraction period may be indicated.
