Background: health-related quality of life (HRQOL) represents a secondary endpoint of medical interventions in oncological patients. Our aim was to highlight potential sources of bias that could be encountered when evaluating HRQOL in oral cancer patients. Methods: this review followed PRISMA-ScR recommendations. Participants: patients treated for oral cancer. Concept: HRQOL assessed by EORTC QLQ-C30 and QLQ-H&N35/QLQ-H&N43. A critical appraisal of included studies was performed to evaluate the accuracy of data stratification with respect to HRQOL determinants. Results: overall, 30 studies met the inclusion criteria, totaling 1833 patients. In total, 8 sociodemographic (SDG) and 15 disease/treatment-specific (DT) HRQOL determinants (independent variables) were identified. The mean number of the independent variables was 6.1 (SD, 4.3)—5.0 (SD, 4.0) DT-related and 1.1 (SD, 1.8) SDG-related variables per article. None of the included papers considered all the identified determinants simultaneously. Conclusions: a substantial lack of evidence regarding HRQOL determinants was demonstrated. This strongly weakens the reliability of the reported findings due to the challenging presence of baseline confounding, selection, and omitted variable biases. The proposed approach recommends the use of further evaluation tools that gather more variables in a single score together with a selection of more homogeneous, reproducible, and comparable cohorts based on the identified baseline confounding.

(1) Background: Medication-related osteonecrosis of the jaws (MRONJ) is an adverse drug reaction characterized by progressive bone disruption and necrosis in the mandibular and/or maxillary bones. It occurs in individuals who have received antiresorptive drugs without prior radiotherapy. Since its first reported cases in the USA in 2003, extensive literature has emerged worldwide, leading to significant advancements in understanding MRONJ’s pathogenesis and management. (2) Results: This article aims to compare the current national recommendations provided by the Italian Society of Maxillofacial Surgery (SICMF)/Italian Society of Oral Pathology and Medicine (SIPMO) and the American Association of Oral and Maxillofacial Surgeons (AAOMS). (3) Conclusions: Historically, the AAOMS advocated for a more conservative approach compared to the Italian guidelines. However, in their 2022 update, the AAOMS adopted a different perspective based on reported evidence, highlighting the advantages of early surgical treatment. Despite resolving some initial controversies, differences still exist between the two sets of recommendations, particularly regarding diagnosis and staging.

One of the most attractive areas of the face are the lips, they are crucial for emotion and communication, both during animation and at rest. Throughout the years, several techniques to obtain permanent lip enhancement have been introduced, such as the use of nonresorbable fillers. The main problem related to permanent fillers is that undesirable results could not always be repaired; although lip sequelae can be addressed surgically, some surgeons will not perform this type of procedure due to its complexity and the lack of guidelines. In this paper, the authors present a case of a labial incompetence developed after lips implant removal performed elsewhere; after clinical examination the patient was planned for surgery, although during preoperative instrumental examination (chest X-ray) a solitary pulmonary nodule was noted; further investigation performed with needle biopsy revealed a lung cancer. For this reason, the surgical procedure planned for lip restoration was not performed; however, the patient asked for a minimally invasive procedure, thus to improve, although temporarily, her lips appearance. For the aforementioned reasons, the patient was treated just with hyaluronic acid injections achieving a pleasant result, solving also the labial incompetence at rest. To the best of the author's knowledge, this paper represents the first one describing the use of hyaluronic acid injections to restore lip competence following surgical removal of permanent implant.

The management of squamous cell carcinoma (SCC) of the tongue represents the most demanding treatment planning in head and neck surgery. Ablation followed by free flap reconstruction is considered the gold standard, but not all patients are suitable for this strategy. The aim of this review is to provide a comprehensive view of surgical reconstruction possibilities in patients not eligible for free flaps. Following PRISMA recommendations, a systematic literature review was conducted searching for original papers that investigated outcomes of patients treated by surgical ablation for tongue SCC followed by reconstruction with local or pedicled flaps. Selected papers were read and data extracted for qualitative analysis. Twenty articles met the inclusion/exclusion criteria. The study design was case series in sixteen papers, cohort study in the remaining four. Four different local flaps (BMM, FAMM, NLIF, SMIF) and four regional flaps have been discussed in included studies (IHF, SFIF, SCM, PMMC). The improved anatomical knowledge makes local flaps a reliable alternative to free tissue transfer in cases requiring small-/medium-sized defects. Regional flaps still represent cornerstones in reconstruction of the tongue. Ease of execution, costs-to-benefit ratio, low-rate complications, minimal donor site morbidity represent the best advantages choosing local/regional flaps.

In humans, the asymmetry in the masseter electromyographic (EMG) activity during clenching is positively correlated with the degree of pupil size asymmetry (anisocoria) at rest. Anisocoria reveals an asymmetry in LC activity, which may lead to an imbalance in cortical excitability, detrimental to performance. Hereby, we investigated, in individual subjects, the possibility that occlusal correction, which decreases EMG asymmetry, improves performance by balancing LC activity. Cognitive performance, task-related mydriasis, and pupil size at rest were modified by changing the occlusal condition. Occlusal-related changes in performance and mydriasis were negatively correlated with anisocoria changes in only 12/20 subjects. Within this population, spontaneous fluctuations in mydriasis and anisocoria also appeared negatively coupled. Occlusal-related changes in performance and mydriasis were negatively correlated with those in average pupil size (a proxy of average LC activity) in 19/20 subjects. The strongest association was observed for the pupil changes occurring on the side with higher EMG activity during clenching. These findings indicate that the effects of occlusal conditions on cognitive performance were coupled to changes in the asymmetry of LC activity in about half of the subjects, while they were related to changes in the average tonic LC activity in virtually all of them.
