We hypothesized that combining these surgical procedures might offer a better quality of life without compromising on surgical outcomes.\u0000\u0000\u0000SUBJECTS & METHODS\u0000A prospective cohort study was conducted at our centre including all adult patients who reported to us for the correction of secondary cleft deformities. All patients with secondary deformities associated with cleft lip palate and alveolus were enrolled in the study. Patients with medical issues who are not fit for general anesthesia, Bilateral Cleft deformities, and patients with gross skeletal deformity warranting surgical correction by Le fort I distraction were excluded from the study. All the patients who were included in the study underwent simultaneous lip revision, rhinoplasty and cleft alveolar bone grafting. The outcome Lip nose profile was assessed using standardised patient photographs with Ascher Mcdade scale and Aesthetic outcome index by 2 blinded maxillofacial surgeons and the bone grafting was assessed using Berglands grading system.\u0000\u0000\u0000RESULTS\u000028 patients were enrolled in the study, 10 patients were excluded based on the exclusion criteria. Thus 18 patients planned for synchronous correction of unilateral secondary cleft deformities were included in the study The Ascher Mcdade score improved from 15 (13- 16), to 4 ( 4- 5) in the post op. All the patients were totally satisfied with the surgical outcome. The aesthetic index showed excellent outcomes in all the lip-nose procedures, except for one case which showed a good outcome. The Bergland scale showed normal bone height in all cases of alveolar bone grafting, except for one case, which showed less than 3/4th fill of bone. No complications were associated with any of the procedures.\u0000\u0000\u0000CONCLUSIONS\u0000Simultaneous correction of multiple secondary cleft lip deformities should be considered when feasible, to improve the psychological benefit and reduce financial burden on these patients.","PeriodicalId":18742,"journal":{"name":"Minerva stomatologica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41949270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
