Abstract
Background: Autologous bone grafts are essential in reconstructive oral and maxillofacial surgery, and depending on the donor site, they can be associated with specific harvesting morbidities. One of the most commonly applied bone grafts is the iliac crest bone graft, irrespective of other grafts, which might be associated with an easier surgical procedure or the possibility of harvesting them under local anaesthesia. Objective of the study is the clinical evaluation of proximal tibia bone grafts regarding their eligibility for maxillofacial bone grafting.
Methods: In this retrospective study, proximal tibia bone grafts were examined with regard to associated donor and recipient site morbidity and their suitability for alveolar ridge augmentation and rhinoplasty.
Results: In total, 21 tibia grafts were included. Fifty-seven percent of the bone grafts were used for alveolar ridge reconstruction, and 43% were used for augmentative rhinoplasty. No significant complications occurred during or after harvesting, but in 14.3% of the patients, minor wound healing disorders were recorded at the donor site, and in 19% of the patients, they were recorded at the recipient site. Statistically, patient sex, age, nicotine and alcohol abuse and metabolic diseases had no significant influence on the complication rate. Graft harvesting under local anaesthesia and at summer temperatures was associated with significantly more complications at the harvesting site (p < 0.05). In cases of dental implant insertion into augmented sites, the implants (n = 31) were followed up for a median period of 40.5 months, during this time 86.7% of the implants survived.
Conclusion: The proximal tibia is a suitable donor site for harvesting autologous bone grafts for alveolar ridge augmentation or rhinoplasty because the donor site morbidity is low, and in contrast to iliac crest bone grafts, they can be harvested under local anaesthesia, which might be advantageous for outpatient surgeries.
期刊介绍:
Head & Face Medicine is a multidisciplinary open access journal that publishes basic and clinical research concerning all aspects of cranial, facial and oral conditions.
The journal covers all aspects of cranial, facial and oral diseases and their management. It has been designed as a multidisciplinary journal for clinicians and researchers involved in the diagnostic and therapeutic aspects of diseases which affect the human head and face. The journal is wide-ranging, covering the development, aetiology, epidemiology and therapy of head and face diseases to the basic science that underlies these diseases. Management of head and face diseases includes all aspects of surgical and non-surgical treatments including psychopharmacological therapies.
