Abstract

Introduction Failure in the fusion of medial nasal processes and maxillary prominences would result in the development of a cleft lip while failure in merging the palatal shelves would result in the development of a cleft palate (CP). At present, patients with a cleft palate (CP) have often undergone corrective surgery before 1 year of age. However, an oronasal fistula (ONF) often remains in the palate after surgery.
Methodology In this historical cohort, 40 patients with CP, 6-10 years old, who had undergone corrective surgery at 1 year of age were selected by targeted sampling and assigned to two groups with ONF (N=20) and without ONF (n=20). The two groups were matched in terms of age and gender. All patients had an intraoral photograph of the maxilla and a lateral cephalogram. Twenty-three cephalometric parameters were measured prior to the orthodontic treatment and compared between the two groups using a t-test.
Results CP patients with ONF had significantly higher Y-axis, gonial angle, Go1, Go2, GoGn-SN, U1-SN, and lower lip to E line compared with those without ONF (P<0.05). The Jarabak index was significantly lower in the CP patients with ONF compared with those without it (P<0.05). The difference in other cephalometric parameters was not significant between the two groups (P>0.05).
Conclusion Patients with ONF had significantly greater growth in the vertical dimension compared with those without ONF. Yet, the difference in the anteroposterior dimension was not significant between the two groups.

Our aim is to publish in the shortest possible time frame and ensure the rapid dissemination of your work via our journal page, but also through our indexing partners…(read more)

STATEMENT

STOMATOLOGY EDU JOURNAL (Stoma Edu J) is a new international dental journal whose main purpose is to inform researchers, educators, graduates, postgraduates and practitioners about the latest trends in the field, which followed, would bring immediate and lasting benefits to the patients; and about opinions of the most authorized specialists on what is best in current practice, for the good of both, patient and dentist.
STOMATOLOGY EDU JOURNAL (Stoma Edu J) is a peer-reviewed, open access international dental journal to be database indexed, meant to contribute to the development and completion of the medical training of practitioners as Dr. Greene Vardiman Black stated: “the professional man has no right to be other than a continual student”.
Open access journal, means that all content is freely available without charge to the user or his/her institution.
