Objective: This study aimed to investigate the application of the palatal approach for surgical removal of IMTM, and to evaluate its success rate, surgical duration, postoperative outcomes, and incidence of complications.
Method: Patients with mesioangularly IMTM (Archer Classification Class B) in the none-buccal position to the adjacent second molar, which were indicated for surgical removal, were enrolled in this study. The patients were assigned into two groups according to the surgical approach: the buccal or palatal approach. The impacted tooth positions, diagnosis, past dental and medical history, and radiographic examination were recorded pre-operatively. The duration, surgery details, and surgical complications were documented during the surgery.
Result: 40 teeth were enrolled in our study. All teeth were removed completely. The operation time was significantly shorter in the palatal approach group compared to the buccal approach group (13.3 ± 2.8 min vs. 22.3 ± 5.5 min, P<0.001). The incidence of traumatic ulcers of the lips was significantly higher in the buccal approach group than in the palatal approach group (7/20 vs. 0/20, P = 0.008).
Conclusion: It is more efficient to perform surgery with a palatal approach if a Class B mesioangularly IMTM is located in the non-buccal aspect of the adjacent second molar.

Background: Compensatory errors are a conventional part of an articulation disorder identified by speech pathologists in patients with Cleft palate (CP). This study aimed to evaluate the effect of new mixed articulation therapy on the perceptual and acoustic features of these errors.
Methods: The single-case experimental design, ABA design, was used in this study.

Objective: The endoscopic endonasal approach (EEA), has become the preferred alternative to traditional open and transoral approaches to the ventral craniovertebral junction (CVJ) region. However, preoperative prediction of the limitations of caudal reach remains challenging. This cadaveric study aimed to quantify the CVJ area of exposure and access afforded by the EEA, evaluate the accuracy of previously described radiographic anthropometric lines, and identify the lowest limit of the EEA corridor.

Objective: This study aims to assess the safety and efficacy of solely using local anesthetics for cleft lip repair and/or revision in adolescent and adult patients.
Design: Systematic review.
Setting: Clinical studies describing the use of local anesthetics in cleft lip repair procedures.
Cleft lip and cleft palate are among the most common congenital defects of the head. The treatment of clefts is centralized, multidisciplinary, and involves a plastic surgeon, orthodontist, anesthesiologist, clinical speech therapist, and other specialists. While the incidence of cleft lip and cleft palate remains approximately unchanged, the approach to their treatment is evolving.

Objective: To evaluate the frequency of tooth anomalies (TA) in the deciduous and permanent dentition of patients with nonsyndromic orofacial clefts (NSOC), both inside and outside the cleft area.
Methods: The following databases were searched for the relevant literature: Cochrane, OVID, SciELO, Embase, Livivo, PubMed, Scopus, and Web of Science. The risk of bias was analyzed using the Joanna Briggs Institute.
