GITTINS, Eymi Valery Cazas Duran; CENTURION PAGIN, Bruna Stuchi; YAEDU, Renato Yassutaka Faria and RUBIRA-BULLEN, Izabel Regina Fischer. Prevalence of posterior superior alveolar canal anastomosis with anterior superior alveolar canal in patients with cleft lip and palate. Rev Esp Cirug Oral y Maxilofac [online]. 2020, vol.42, n.1, pp.20-24. Epub May 04, 2020. ISSN 2173-9161. https://dx.doi.org/10.20986/recom.2020.1056/2019.
Objectives:
The purpose of this study was to examine the prevalence of intraosseous anastomosis (AIO) between the posterior superior alveolar canal (CASP) and the anterior superior alveolar canal (CASA) in patients with cleft lip and palate, comparing the side affected by unilateral incisive trans-forame fissure (FLP) with the contralateral side not affected by fissure (NF).
Material and method:
A total of 1500 Cone Beam Computed Tomography (TCHC) were evaluated and, according to inclusion criteria, 95 TCHC were selected for analysis (52 men, 43 women, average age 27 years). The sample consisted of 1) patients with FLP on the right side and NF on the left side; and 2) patients with FLP on the left side and NF on the right side. The analysis was divided into 4 steps: 1) Intra and inter-rater calibration; 2) evaluating presence or absence of AIO anastomose between the CASP with CASA; 3) Location of the AIO anastomose between the CASP with CASA, as reference to the mesial aspect of each tooth (17/27), (16/26), (15/25) and (14/24); 4) Evaluated symmetry/asymmetry the localization of AIO, comparing them side with FLP, with the contralateral side NF.
Results:
The total prevalence of AIO was 67.9 %. The prevalence in FLP side was 71.6 %, and NF side was 64.2 % (Fisher's test > 0.35). The location of the AIO in the FLP side was more than prevalent in the areas of (15/25), (16/26) and on the NF side, it was in the area (14/24) (Chi-square test < 0.03). The AIO was 71.5% (Fisher's test > 0.03) asymmetric comparative of the FLP side with the contralateral NF.
Conclusions:
The prevalence of AIO was higher in FLP side (71.6 %) comparing the NF side (64.2 %). The location of AIO, in the FLP side was dislocated distally when compared with the contralateral side NF. The AIO was asymmetric in 71.5% of the cases. This information is relevant in surgical procedures that are performed in patients with cleft lip and palate, which aim to correct maxillomandibular discrepancies.
