Children with cleft palate are more prone to develop this condition. This is caused by impaired eustachian tube function in cleft palate. They may present with hearing loss, delayed speech, and language development or poor social behavior. This is a significant cause of conductive hearing loss in the early speech-forming years of their life. Even after an early surgical repair of palate, speech and language defects are frequently identified during regular postoperative follow-up by speech-language pathologists.

The distance from the antilingula to hole was measured and recorded in both antero-posterior and supero-inferior planes. The data were collected and put to statistical analysis.</p><p><strong>Results: </strong>From this study, it was concluded that the antilingula was present in 90% (n = 45) of mandibles and was absent in 10% (n = 5) of mandibles. Antero-posteriorly, the antilingula was present anterior to mandibular foramen in 22.2% (n = 10) of mandibles, posteriorly in 57.7% (n = 26) of mandibles, and there was complete concordance in 20% (n = 9) of mandibles. The supero-inferior relation shows that antilingula was present superior to mandibular foramen in 97.8% (n = 44) of mandibles, and it was present inferiorly in 2.20 (n = 1) of mandibles.</p><p><strong>Conclusion: </strong>Although vertical ramus osteotomy is not a commonly used procedure in these days. From our study, it was concluded that antilingula was present as an elevation in 90% of cases on the lateral ramus border and the mandibular foramen is present inferior and anterior to the antilingula.</p>","PeriodicalId":101444,"journal":{"name":"National journal of maxillofacial surgery","volume":"15 2","pages":"228-232"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11371280/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142134988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
