Abstract: | The percutaneous trephine technique uses a bone marrow biopsy needle to harvest cancellous bone graft from the anterior iliac
crest. The subjects of this study were 41 patients with 47 alveolar clefts who underwent secondary bone grafting over a period
of 5 years, using the above technique. The donor site morbidity was evaluated retrospectively by means of a postal questionnaire
and case note survey. Patients were questioned about severity of pain, duration of pain and duration of limping. None of the
patients had donor site pain or limping for more than 2 weeks. No patient had severe donor site pain. Case note surveys revealed
no donor site complications of haematoma, sensory disturbance, wound breakdown or contour abnormality. In 85.10% (n=40) of the alveolar clefts where the canine tooth had reached its final position at the bone grafted site, dental radiographs
were used to assess the interalveolar septal height. In 82.5% (n=33) the interalveolar septal height was more than three quarters of normal i.e. a successful result. In conclusion the percutaneous
technique causes minimal donor site pain and gait disturbance. It is a simple and safe technique, easy to learn and quick
to perform leaving the patient with an imperceptible donor site scar. The results of clinical and radiological assessment
of the quality of the bone graft also compare favourably with the conventional open technique of harvesting iliac crest graft
in cases of alveolar clefts.
