Abstract
Aim: The aim of this study was to introduce and assess a new computer guided algorithm using locating holes and cutting guides, for mandibular segmental resection in cases with massive contour deformity.
Patients and Methods: This was a prospective study conducted on 6 consecutive cases with mandibular odontogenic neoplasms indicating lateral segmental mandibular resection. For all the patients, computer guided resection and titanium plate reconstruction using locating holes and cutting guides was performed. The patients were followed up for 6 months; and recurrence, appearance, occlusion, maximum incisal opening (MIO), midline shift, chewing, swallowing, speech, pain were recorded.
Results: No recurrence occurred in the study till the end of follow up period. 33.3 % of the observed minor change in appearance, and 66.7 % observed no appearance change. No major disruption in occlusion occurred for any patient. The mean MIO was 41.8 ± 4.35 mm after 1 month, 42.3 ± 3.98 mm after 6 months, with no statistically significant difference. Chewing, swallowing, and speech were as normal for 5 patients (83.3 %).
Conclusions: The computer guided resection and titanium plate reconstruction using locating holes and cutting guides was found to be beneficial with promising results regarding function and aesthetics, we recommend the use of this technique for initial resection and reconstruction in delayed grafting. Yet, its use as a definitive reconstruction should be subjected to longer follow up period studies.
