Abstract
BackgroundThird molar removal surgery is the most frequently performed surgery in the oral and maxillofacial field with a wide range of items in the quantification of postoperative complications. For their measure, in 2014 a previous scale design was presented. The aim of this study was to determine the reliability and validity of a scale designed to measure and quantify postoperative complications in third molar surgery (TMS).MethodsA cross-sectional study of a measurement model was designed. Sixty-two patients (mean age 20.5 ± 6.6 years; 36 women) underwent TMS in three Chilean hospitals. In the postoperative check-up on the 7th day, a maxillofacial surgeon and a surgical resident performed independent postoperative assessments, applying the scale. A confirmatory factor analysis was conducted to obtain validity, internal consistency, interobserver reliability and a score to categorize the severity of complications using structural equation model analysis.ResultsNine patients (14.5%) had complications. The scale was defined by two components: “Secondary complication” and “Infection” (Cronbach’s alpha 0.71; Interobserver reliability 87.7%) and three categories of postoperative complication: “without or mild”, “moderate” and “severe”.ConclusionThis study presents a reliability and validity scale called “Surgical complication assessment scale in TMS”.
Highlights
Third molar removal surgery is the most frequently performed surgery in the oral and maxillofacial field with a wide range of items in the quantification of postoperative complications
There is a wide range of items in the quantification of post-operative complications [2], which can appear in up to 75% of cases [3]. This great variability is due to the various factors: inconsistency in the diagnostic criteria and assessment methods used in the different studies, variation in surgical technique, the surgeon’s ability and experience, patient variability and the absence of valid and reliable measurement instruments to record objective and subjective postoperative complication variables [4,5,6,7]
During the period of study a total of 254 patients were attended for third molar surgery (TMS) in three Chilean hospitals, of which only 62 were selected according to the selection criteria and recording of complete data
Summary
Third molar removal surgery is the most frequently performed surgery in the oral and maxillofacial field with a wide range of items in the quantification of postoperative complications For their measure, in 2014 a previous scale design was presented.

The validity and reliability proprieties of this scale must be analyzed in order to contribute a new instrument that facilitates its clinical use and benefits the rapid classification of clinical status
