| Popis: | Background Although many trials have been made to augment the unilateral alar base depression, the ultimate aesthetic satisfaction has proven difficult to achieve. In our study, we present a novel submucosal dissection technique to harvest the vomer bone and use it as an onlay graft to correct the alar base depression. Methods We collected a prospective cohort study of 11 patients with unilateral cleft lip nasal deformity. Using CorelDRAW X7 software, we obtained perioperative clinical photographs to analyze the nostril and lateral lip morphometric measurements on the cleft side. Computed tomography scans were used to assess the required graft's volume and to detect resorption. We performed vomerine ostectomy and placed and fixed the bone graft in with a lag screw over the alar base depression. Results The nostril width showed a significant increase, in addition to the height/width ratio. The columellar angle with the lateral lip height increased remarkably, with a general improvement in the nasal tip aesthetics. Conclusions The vomer bone graft has been shown to correct the lateral and inferior disorientation of the alar base and improve the nostril and nasal tip aesthetic measurements. The vomer bone is therefore a sufficient bone source for grafting with high viability and no resorption. |
