In third molar surgery, it is important to take into account multiple clinical and radiographic variables that, grouped into indices and classifications, allow estimating the degree of surgical difficulty. The present study proposes to evaluate the efficacy and congruence of these indices. Material and methods: a cross-sectional retrospective study in 77 patients. 123 lower third molar surgeries were performed using the Pederson, WHARFE and Parant prediction indices; to know the efficacy of the classifications, a statistical analysis with measures of central tendency, association through chi-square test and tables of frequency distribution were used, as well as non-parametric tests when determining an asymmetric distribution in the data through the Kolmogorov and Kruskall-Wallis test. Results: Analyzing the correlation between the Pederson and WHARFE indices, a strong association of P = .906 (Gamma), P = .761 (Kendall’s Tau “C”) and P = .834 (Somers “D”) was found, accepting frequency correlation through chi-square test. X2 test (P = 0.000) was performed accepting association between the Parant and Pederson scale, as well as for the WHARFE and Parant scales, resulting positive with a strong intensity and a direct association with a P = 0.796 (Gamma). Discussion: The difficulty prediction indices evaluated in the present study proved to be congruent with each other, their predictions regarding the type of surgery performed allow estimate degrees of complexity, type of surgical procedure, approximate time and possible complications, thus improving treatment planning.

在第三磨牙手术中，重要的是要考虑多种临床和影像学变量，将其分组为指标和分类，以便估计手术难度。本研究拟对这些指标的有效性和一致性进行评价。材料和方法:对77例患者进行横断面回顾性研究。采用Pederson、WHARFE和parent预测指数进行下第三磨牙手术123例;为了了解分类的有效性，使用了集中趋势、卡方检验关联和频率分布表的统计分析，以及通过Kolmogorov和Kruskall-Wallis检验确定数据不对称分布时的非参数检验。结果:分析Pederson指数与WHARFE指数之间的相关性，发现P = .906 (Gamma)、P = .761 (Kendall 's Tau " C ")和P = .834 (Somers " D ")存在较强的相关性，通过卡方检验接受频率相关。对parent量表与Pederson量表、WHARFE量表与parent量表的相关性进行X2检验(P = 0.000)，结果为阳性，阳性强度强，呈正相关，P = 0.796 (Gamma)。讨论:本研究评估的难度预测指标相互一致，其对手术类型的预测可以估计手术的复杂程度、手术类型、大概时间和可能的并发症，从而改进治疗计划。关键词:第三磨牙;难度;外科拔牙;预测

Introduction: Inverted papilloma (IP) is the most common type of Schneiderian papilloma originating from the mucosal lining of the nose and paranasal cavities. It is a semi benign tumor with a high tendency for recurrences and malignant transformation. Management consists of a complete tumoral resection. Objective: to analyze surgical results considering the techniques (open or endoscopic surgery), the rate and time of recurrence. Method: We present herein a cohort of 61 patients treated in the CHU-UCL Godinne between 1998 and 2019. We analyzed the demographic data, the origin of the tumor, the staging, the surgical approach and the outcomes. The patients were classified into two groups: the first one includes 48 patients operated de novo in CHU-UCL Godinne and the second group 13 patients referred to us for revision surgery. Results: We observed 8 recurrences, all groups confounded. The global success rate was 87%. The number of recurrences in the first group was 6 out of 48 and 2 out of 13 in the second group. Following these results we propose an algorithm of treatment depending on the site of attachment of the IP. Conclusion: We confirmed that more extended surgeries such as Caldwell Luc procedure, medial maxillectomy, Draf IIb/III frontal sinusotomy or type III sphenoidotomy give better outcomes than more “limited” and functional surgeries such as Draf I/IIa frontal sinusotomy or middle antrostomy. The latter should be done only for specific and limited extension of the IP in the maxillary sinus. A subperiosteal dissection is mandatory in all cases. Keywords: inverted papilloma; retrospective study; surgery; recurrence
