Evaluating the reproducibility and validity of maximal mouth opening measurement techniques.

Objectives: A limitation of the maximal mouth opening (MMO) is a frequent complication of oral (cancer) surgery. The measurement between the right central incisors is considered the golden standard for assessing MMO, although it has been noted to overestimate MMO in edentulous patients. This study aims to evaluate the reproducibility and validity of four MMO techniques and to determine the extent to which they are dependent on the remaining dentition.

Morphological characteristics of coronoid process and revisiting definition of coronoid hyperplasia.

The aim of this study was to assess the morphological characteristics of the coronoid process (CP) and define coronoid hyperplasia (CH) using cadaveric mandibles of a Caucasian population. A sample of 151 adult dry cadaveric mandibles (302 CPs) was acquired. Three distances were measured, which included the width, height, and length of CP.

Value of six comorbidity scales for predicting survival of patients with primary surgery for oral squamous cell carcinoma.

Background: Comorbidities influence treatment outcome of oral squamous cell carcinoma (OSCC). This study compared the predictive performance of six comorbidity scales for overall survival after surgery for OSCC.

Methods: We retrospectively analyzed OSCC patients, surgically treated at an academic center in Belgium between January 01, 2000 and January 01, 2020.

A Retrospective Analysis of a Cohort of Patients Treated With Immune Checkpoint Blockade in Recurrent/Metastatic Head and Neck Cancer.

Objective: The treatment approach of recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) has long been similar for all patients. Any difference in treatment strategy was only based on existing comorbidities and on preferences of the patient and the treating oncologist. The recent advance obtained with immune therapy and more specifically immune checkpoint blockade (ICB) has been a true game changer.

The Effectiveness of Surgical Methods for Trismus Release at Least 6 Months After Head and Neck Cancer Treatment: Systematic Review.

Background: The objective of this systematic review was to identify the different surgical treatment modalities of severe trismus after head and neck squamous cell cancer treatment.

Methods: An electronic literature database search was conducted in Medline, Embase, Cochrane, Web of Science, and OpenGrey to determine articles published up to September 2021. Two observers independently assessed the identified papers for eligibility according to PRISMA guidelines.

Complications Following One-Stage Versus Two-Stage Surgical Treatment of Transverse Maxillary Hypoplasia.

Purpose: Contemporary literature suggests a similar transverse stability of a surgical-assisted rapid palatal expansion and a segmented Le Fort I osteotomy. The aim of this study was to compare postoperative complications of 1-stage (segmental maxillary osteotomy) and 2-stage (surgical-assisted rapid palatal expansion followed by Le Fort I osteotomy) treated patients to determine the preferred treatment strategy.

Materials And Methods: This retrospective study included 74 consecutive patients (age range: 14 - 57 years; 36 males, 38 females) with a moderate transverse maxillary hypoplasia: 32 patients were treated in a 1-stage protocol and 42 in a 2-stage protocol with a postoperative follow-up of at least 1 year.

Late reconstruction of extensive orbital floor fracture with a patient-specific implant in a bombing victim.

Fractures of the orbital floor and walls are among the most frequent maxillofacial fractures. Virtual three-dimensional (3D) planning and use of patientspecific implants (PSIs) could improve anatomic and functional outcomes in orbital reconstruction surgery. The presented case was a victim of a terrorist attack involving improvised explosive devices.

A retrospective analysis of the complication rate after SARPE in 111 cases, and its relationship to patient age at surgery.

Purpose: Surgically assisted rapid palatal expansion (SARPE) is a well-known surgical intervention for treating maxillary transverse deficiencies (MTDs). This investigation aimed to evaluate the complication rate after SARPE, and its relationship to patient age.

Materials And Methods: Based on multivariate analyses, the complication rate after SARPE and its association with increasing age in 111 patients with MTD was evaluated.

Is there need for technical investigations in order to predict potential length of hospital stay of oral infections?

Objective: Oral and maxillofacial infections are generally treated by primary dental or medical caregivers. Nevertheless, because these infections are known to have life-threatening complications, there is a need of clear indicators for emergency services medical staff, particularly in determining when morbidity can be expected and when in-hospital treatment is required. This retrospective study aimed to identify variables that were observable at admission, which could indicate high complication rates, long hospital stays, and/or a need for tracheostomy.
