Abstract Sinoliths are rarely found calculi of paranasal sinuses. The most rarely they were found in the sphenoidal sinuses. At a routine Cone Beam CT exam of a 52-year-old male patient clinically silent small sinoliths were found bilaterally in the sphenoidal sinuses and a larger posterior ethmoidal sinolith was found on the right side. To our knowledge, such multiple sinuses involvement has not been previously reported.

Abstract Sinoliths are calculi found particularly in paranasal sinuses, the rarest location being the ethmoid air cells. There were previously reported only 4 cases of unilateral large ethmoidal sinoliths (ES), this one being the fifth report. We report here the incidental bilateral evidence in a 34-year-old female patient evaluated in Cone Beam Computed Tomography (CBCT) of minor ES. The left ES, of 1.6 mm2 sagittal size, occupied the suprabullar cell, in front of the ground lamella and behind the anterior ethmoidal canal. The right ES, of 7.6 mm2, was located behind the ground lamella. The radiodensity of each ES was about 1000 HU, their bone quality being thus assessed. This is the first evidence of bilateral and clinically silent ethmoidal sinoliths. Being small-sized and incidentally found, it seems reasonable to consider that ethmoidal sinoliths could have a higher incidence but they are overlooked due to the lack of clinical manifestations.

The study aimed to establish and evaluate anatomoradiological landmarks in trigeminal neuralgia patients using computed tomography (CT) and cone-beam CT. CT images of 40 trigeminal neuralgia (TN) and 40 healthy individuals were retrospectively analyzed and enrolled in the study. The width and length of the foramen rotundum (FR), foramen ovale (FO), foramen supraorbitale, and infraorbitale were measured. The distances between these foramen, between these foramen to the median plane, and between the superior orbital fissure, FO, and FR to clinoid processes were also measured bilaterally. Variations were evaluated according to groups. Significant differences were found for width and length of the foramen ovale, length of the foramen supraorbitale, and infraorbitale between TN and control subjects (p < 0.05). On both sides, FO gets narrower and the length of the infraorbital and supraorbital foramen shortens in the TN group. In most of the control patients, the plane which passes through the infraorbital and supraorbital foramen intersects with impression trigeminale; 70% on the right-side, and 67% in the left-side TN groups. This plane does not intersect with impression trigeminale and deviates in certain degrees. The determination of specific landmarks allows customization to individual patient anatomy and may help the surgeon achieve a more selective effect with a variety of percutaneous procedures in trigeminal neuralgia patients.

Abstract Background Quantitative and qualitative analysis of several periodontal parameters plays an important role in several dental procedures. Aim of the current study was to assess gingival thickness (GT) at mandibular incisors of orthodontic patients with two methods and determine how these methods are compared to each other when assessing periodontal anatomy through soft tissue thickness.Methods The sample consisted of 40 consecutive adult orthodontic patients. GT was measured at both central mandibular incisors, mid-facially on the buccal aspect, 2mm apically to the free gingival margin with two methods: a) clinically with an Ultrasound device (USD) and b) radiographically with Cone Beam Computed Tomography (CBCT).Results CBCT measurements were consistently higher than USD measurements, with the difference ranging from 0.13 mm to 0.21 mm. No difference was noted between the repeated CBCT measurements at the right central incisor (Bias= 0.05 mm; 95% CI= -0.01, 0.11, p=0.104). Although the respective results for the left incisor indicated, statistically, that the measurements were not exactly replicated, the magnitude of the point estimate was small and not clinically significant (Bias= 0.06 mm; 95% CI= 0.01, 0.11, p=0.014). Small differences between CBCT measurements made by the 2 examiners at the left central incisor (bias= 0.06 mm, 95% CI= 0.01, 0.11, p=0.014) were detected. However, this difference was minor, and again, not clinically significant. The respective analysis on the right incisor showed no significant difference (bias= 0.05 mm, 95% CI= -0.01, 0.11, p=0.246).Conclusions Present data indicate that CBCT measurements were highly reproducible and yielded greater values compared to USD measurements.

This retrospective, observational, longitudinal study performed a morphometric analysis of the pterygopalatine fossa (PPF) in patients undergoing surgically assisted rapid maxillary expansion (SARME) using cone beam CT (CBCT). CBCT scans of 41 consecutive patients were assessed and the following measurements were performed: PPF volume (PPFV), height (PPFH), length (PPFL) and angle (PPFA). The sample was divided into groups D (patients undergoing SARME; n=26) and control (n=15). Group D was subdivided into D+ (with pterygomaxillary disjunction – PMD) and D- (without PMD). The differences between the pre and postoperative periods were tested using the U Mann-Whitney or the t-test. Groups D+ and D- were compared using the one-way ANOVA or Kruskal-Wallis tests (level of significance set at 5%). In general, there were morphometric variations in PPF, with lower values after SARME. Differences for PPFH, PPFL and PPFA were not significant (p>0.05). On the right side, there were differences in PPFV, with lower values in patients from group D+ (p<0.05). These findings indicate a morphometric reduction of PPF after SARME, with differences when the disjunction is performed or not. The maxillofacial surgeon must be aware of these changes when performing SARME with or without disjunction.

Abstract BACKGROUND. The infraorbital recess of the maxillary sinus can reach in front of the nasolacrimal duct to become prelacrimal recess. During a routine Cone Beam CT (CBCT) study of a male patient of 72 years old, there were bilaterally found infraorbital maxillary air cells (IMACs) resulted after the almost complete closure of infraorbital recesses of the maxillary sinuses. Only that on the left side was reaching in front of the nasolacrimal canal. The closure of each infraorbital recess leaded to a narrow draining passage opened in the terminal end of the maxillary infundibulum, thus proximal to the maxillary sinus ostium. On the left side, a small cell of the lacrimal bone was interposed between the IMAC drainage pathway and the nasolacrimal canal. On the right side, the nasolacrimal canal was communicating with the ethmoidal infundibulum. Such an anatomic variation in the infraorbital angle of the maxillary sinus can impede the endoscopic procedures which use the anterior lacrimal pathway.

The aim of the present study was the determine the location of the mental foramen and accessories, their relationships with the alveolar and basal rims found in Peruvians adults. A descriptive, transverse and retrospective study was carried out. The sample was composed of 100 cone beam CT scans of patients, between the ages of 20 to 55 years of age, these patients were attended at the clinic of the Faculty of Dentistry of Mayor National University of San Marcos UNMSM. Were considered tomograms of mandibular dentate patients taken during 2015, classified according to age and sex, identifying in them the location of the mental foramen and accesories in relation to a lower tooth, according to the classification of Al Jasser- Nwoku.The distance of the mental foramen on the left side to the alveolar ridge had an average of 12.62 mm and on the right side it had a mean of 12.90 mm and the distance from the mandibular ridge on the left side showed an average of 14.14 mm and on the right side was 13.91 mm. The relationship of the mental foramen to the teeth was located below the second mandibular premolar. The 14% presented accessory hole, predominating position 4 (at the level of the second premolar).
