CONCLUSION
ABG is a complex procedure requiring interdisciplinary effort in order
to achieve the intended results. We have presented a case where ABG was
performed using unconventional donor sites such as the maxillary
tuberosity and mandibular wisdom molar odontectomy sites to harvest
significant amounts of bone. The intramembranous bone harvested from
these sites achieved complete osseointegration with minimal resorption
after grafting. Therefore, these could be identified as alternative
donor sites during the pre-operative assessment of patients requiring
ABG secondary to cleft lip and palate. Furthermore, where there is
immense scarring making local tissues unsuitable oro-nasal fistula
repairs, a tongue flap may be a good alternative to close the fistulae.
