Efficacy of auriculotherapy in the control of pain, edema, and trismus following surgical extraction of the lower third molars: a split-mouth, randomized, placebo-controlled, and triple-blind study.

BACKGROUND: The aim of this split-mouth, randomized, placebo-controlled, and triple-blind study was to evaluate whether auriculotherapy had any effect on the post-operative course after the extraction of third molars in terms of the control of pain, edema, and trismus. MATERIALS AND METHODS: The study included 42 patients (84 teeth) who had undergone a surgical extraction of the lower third molars. In each patient, the two extractions were randomly assigned to two study groups. In the therapy group, the patients underwent auriculotherapy with vaccaria seeds applied with patches in 6 ear points. In the control group, the patches were applied, without seeds, to the same ear points. After the extraction, the patients were asked to stimulate the ear points three times a day and whenever they felt pain. The patients were asked to keep a diary in which they assessed their pain by means of the Visual Analog Scale (VAS) for 8 days. Edema and trismus were assessed 1, 2, 3, and 8 days after surgery. RESULTS: The differences between the two groups were statistically significant at the 12-h control (auriculotherapy group (AG) VAS 5.5 [IQR 4.25-6.75], placebo group (PG) VAS 6 [IQR 5-8], p = 0.040), after 24 h (AG VAS 5 [IQR 4-6], PG VAS 6 [IQR 4.25-7], p = 0.024), after 2 days (AG VAS 4 [IQR 3-5], PG VAS 4.5 [IQR 4-6], p = 0.044), and after 3 days (AG VAS 3 [IQR 0-5], PG VAS 4 [IQR 3-5], p = 0.024). Throughout the observation period, the AG took a significantly lower number of painkillers than the PG (AG 6 [IQR 4.25-7]; PG 8 [IQR 8-9], p < 0.001). There were no significant differences in the levels of edema and trismus between the two groups throughout the observation period. CONCLUSIONS: On the basis of the results of the present study, auriculotherapy can be considered as a cost-effective adjuvant pain reliever treatment in patients undergoing an extraction of the lower third molars.

Changes in hospital admissions for facial fractures during and after COVID 19 pandemic: national multicentric epidemiological analysis on 2938 patients.

PURPOSE: The objective of this multicenter study was to examine the differences in maxillo-facial fractures epidemiology across the various phases of the SARS-CoV-2 pandemic. METHODS: This is a retrospective study on patients who underwent surgery for facial bone fractures in 18 maxillo-facial surgery departments in Italy, spanning from June 23, 2019, to February 23, 2022. Based on the admission date, the data were classified into four chronological periods reflecting distinct periods of restrictions in Italy: pre-pandemic, first wave, partial restrictions, and post-pandemic. Epidemiological differences across the groups were analysed. RESULTS: The study included 2938 patients. A statistically significant difference in hospitalization causes was detected between the pre-pandemic and first wave groups (p = 0.005) and between the pre-pandemic and partial restriction groups (p = 0.002). The differences between the pre- and post-pandemic groups were instead not significant (p = 0.106). Compared to the pre-pandemic period, the number of patients of African origin was significantly higher during the first wave and the post-pandemic period. No statistically significant differences were found across the periods concerning gender, age, fracture type, treatment approach, and hospital stay duration CONCLUSIONS: The COVID-19 pandemic brought about significant changes in fracture epidemiology, influenced by the restrictive measures enforced by the government in Italy. Upon the pandemic's conclusion, the fracture epidemiology returned to the patterns observed in the pre-pandemic period.

Three-dimensional evaluation of symmetry in facial palsy reanimation using stereophotogrammetric devices: A series of 15 cases.

Facial palsy can severely compromise quality of life, significantly altering the harmony and symmetry of the face, which can be restored by surgical rehabilitation. The aim of the study was the quantification of facial symmetry following facial reanimation. Fifteen consecutive adult patients were surgically treated through triple innervation for reanimation of flaccid unilateral facial paralysis (contralateral facial nerve, masseteric nerve, and hypoglossal nerve) and fascia lata graft for definition of the nasolabial sulcus. In the preoperative stage and at least 11 months after the surgical treatment, three-dimensional facial images were recorded through stereophotogrammetry in a neutral (rest) position, and with Mona Lisa and full-denture (maximum) smiles. Labial commissure inclination relative to the interpupillary axis, and a surface assessment of local facial asymmetry at rest and while smiling were obtained for the upper, middle, and lower facial thirds. The angle between the interpupillary axis and the labial commissure significantly improved in post-surgical acquisitions, regaining symmetry at rest (t-test; p < 0.001). Facial symmetry increased significantly when passing from pre-to postsurgical facial scans, from the lower to the upper facial third, and from the full smile to the rest position (ANOVA; p < 0.001). After treatment, the full smile recovered more symmetry than the other two expressions. In summary, surgical treatment significantly reduced facial asymmetry, but this reduction differed significantly among the various animations and facial thirds. The results of this study confirmed clinical findings of significant static and dynamic improvements in facial symmetry after triple innervation reanimation surgery.

Are YouTube Videos a Useful and Reliable Source of Information for Patients with Temporomandibular Joint Disorders?

Counseling is considered a first-line conservative therapy with respect to temporomandibular joint disorders (TMJD). Nowadays, 50 to 80% of patients acquire health information from the internet before turning to professionals. The purpose of this study has been to investigate the quality of information about TMJD that patients can obtain from YouTube. A YouTube.com search was conducted using the terms "temporomandibular joint disorder"; "limited movement of the mandible"; and "mandibular joint pain". The videos identified were assessed independently by two panels of three professional and lay reviewers with HONcode, modified DISCERN (MD) and the global quality scale (GQS). A total of 106 videos were included. The professional reviewers reported a mean HONcode score of 4.148 ± 1.314 and a mean MD score of 2.519 ± 1.267, testifying to a modest general quality of the videos. The mean GQS score was 2.987 ± 1.012 for the professional and 3.469 ± 0.891 for the lay reviewers (p < 0.001). The correlations between the ratings were significant between the reviewers within the same group but not between the two groups. The presence of animations significantly influenced the GQS score expressed by the lay reviewers (p = 0.011) but not that of the professionals (p = 0.640). The quality of the information on TMJD on YouTube is generally of poor quality. Healthcare systems and professionals should be prepared to correct misinformation and build trusting relationships with patients which are based on quality counseling. Similarly, academic institutions should produce quality content that leads patients with TMJD toward a correct diagnostic-therapeutic process.

Electrocautery, Harmonic, and Thunderbeat Instruments in Parotid Surgery: A Retrospective Comparative Study.

The aim of this retrospective study has been to compare the surgical outcomes of patients undergoing superficial parotidectomy with three different instruments: bipolar electrocautery, ultrasound, and mixed energy instruments. The clinical records of 102 patients who had undergone superficial parotidectomy for benign tumors between January 2016 and April 2022 were considered. Based on the tool used during the surgery, the patients were divided into three study groups: classic electrocautery hemostasis group (CH group), ultrasonic instrument group (HA group), and combined energy instrument group (TB group). The duration of surgery, the total post-operative drainage volume, and the intra-operative blood loss were significantly higher in the CH group compared to the HA and the TB group, while the differences were not significant between the latter two groups. Facial nerve weakness was detected in 45.9% of the CH group, 12.5% of the HA group, and 21.2% of the TB group. The rate of facial nerve dysfunction in the CH group was significantly higher than in the HA group (0.011). In the patients who experienced post-operative facial nerve dysfunction, the recovery time was significantly shorter in the HA group compared to the CH and the TB group. The HA and TB groups have demonstrated comparable and significantly better surgical outcomes than bipolar electrocautery. Ultrasound instruments have been shown to cause, in comparison with the other techniques, a lower rate of temporary facial nerve dysfunction and, if this is present, lead to a faster spontaneous recovery time.

Bad splits in bilateral sagittal split osteotomy: A retrospective comparative analysis of the use of different tools.

This study aims to analyse the relationship between the incidence of bad splits and the surgical tools adopteded to perform bilateral sagittal split ramus osteotomy (BSSRO).BSSROs performed by the same experienced surgeon period were reviewed, retrospectively. The patients were divided into three groups according to the surgical instrument used to perform the osteotomy: a Lindemann burr, reciprocating saw or piezosurgery. Among the 1120 BSSROs performed, 5 bad fractures were detected during the observation period: 3 among patients operated with the Lindemann burr (0.8%) and 2 among those operated with a reciprocating saw (0.5%). There was no significant correlation between the bad split rate and age and gender of the patients, the type of malocclusion or the type of instrument used to perform the osteotomy. Within the limitations of the study it seems that the the choice of the osteotomy tool for BSSRO does not influence the rate of bad fractures and, therefore, the selection of the osteotmy tool should be left to the discretion of the surgeon.

The Effects of Persistent Olfactory and Gustatory Dysfunctions on Quality of Life in Long-COVID-19 Patients.

(1) Background: Persistent olfactory (POD) and gustatory (PGD) dysfunctions are one of the most frequent symptoms of long-Coronavirus Disease 2019 but their effect on the quality of life (QoL) of patients is still largely unexplored. (2) Methods: An online survey was administered to individuals who reported to have had SARS-CoV-2 infection at least 6 months prior with persisting COVID-19 symptoms (using the COVID symptom index), including ratings of POD and PGD, and their physical (PCS) and mental (MCS) components of quality of life were assessed using the standardized short form 12 questionnaire (SF-12). (3) Results: Responses from 431 unique individuals were included in the analyses. The most frequent persistent symptoms were: fatigue (185 cases, 42.9%), olfactory dysfunction (127 cases, 29.5%), gustatory dysfunction (96 cases, 22.3%) and muscle pain (83 cases, 19.3%). Respondents who reported persisting muscle pain, joint pain, fatigue, headache, gastrointestinal disturbances, and dyspnea had significantly worse PCS. Those experiencing persistent fatigue and dyspnea also showed significantly lower MCS. Respondents reporting POD or PGD showed significantly worse QoL, but only pertaining to the MCS. Multiple regressions predicted MCS based on olfactory and marginally on gustatory ratings, but not PCS. Age significantly affected the prediction of PCS but not MCS, and gender and temporal distance from the COVID-19 diagnosis had no effect. (4) Conclusions: POD and PGD are frequent symptoms of the long-COVID-19 syndrome and significantly reduce QoL, specifically in the mental health component. This evidence should stimulate the establishment of appropriate infrastructure to support individuals with persistent CD, while research on effective therapies scales up.

Tactile recovery assessment with shortened Semmes-Weinstein monofilaments in patients with buccinator myomucosal flap oral cavity reconstructions.

BACKGROUND: The sensitive restoration is a primary aim of oral reconstructive surgery. The Semmes-Weinstein monofilament test is the "Gold Standard" to assess the threshold of tactile sensitivity on the skin but its use in the oral cavity is limited due to the size of the tools. We adopted half-cut Semmes-Weinstein monofilaments to evaluate the threshold of tactile sensitivity in oral reconstructions with buccinator myomucosal flaps. MATERIALS AND METHODS: Monofilaments were half-cut and recalibrated. Fifty-seven oral reconstructions were considered at 4-year minimum follow-up. Test was conducted both on the reconstructive flap and on the non-operated contralateral side. RESULTS: All of the considered flaps (100%) showed a recovery of tactile sensitivity. The overall average tactile threshold value assessed on this sample was 0.76 ± 1.58 g/mm2 overall. CONCLUSIONS: Shortened monofilaments allow easily assessment of tactile sensitivity in all the oral cavity areas, even in operated patients which often present lockjaw or microstomia.

Sensory recovery of myomucosal flap oral cavity reconstructions.

BACKGROUND: Sensory restoration of the oral cavity is a primary aim of reconstructive surgery in posttraumatic or postablative defects. Sensitivity plays a key role in oral function, whose impairment strongly affects the patient's quality of life. Cheek myomucosal flaps provide a reliable and tissue-like reconstruction of these regions but their sensitive recovery, which we still know little about, deserves thorough assessment. METHODS: In this retrospective study, the myomucosal cheek flaps were tested for different aspects of sensory recovery: touch; 2-point discrimination; pain; sharp/smooth discrimination; ability to feel hot/cold stimulus; stereognosis; and taste. RESULTS: Fifty-two myomucosal flap reconstructions were investigated. All sensitivity tests showed positive results. When comparison was possible, sensitivity seemed significantly close to the contralateral healthy side. Sensory recovery proved to be even better than that reported on reinnervated microvascular free flap reconstructions of the oral cavity. CONCLUSION: Myomucosal flap reconstruction demonstrated a high degree of sensory recovery.

Rational and simplified nomenclature for buccinator myomucosal flaps.

BACKGROUND: Reconstruction of moderate-sized mucosal defects of the oral cavity or oropharynx represents a surgical challenge. Buccinator myomucosal flaps seem to provide "ideal reconstruction" of oral/oropharyngeal defects because they carry a thin, mobile, well-vascularized, and sensitive tissue, like that excised or lost. Nevertheless, these flaps are not immediately popular because of confusion surrounding the complex terminology used to name them. METHODS: After a retrospective study on our experience and a literature review, the authors propose a new rational and simplified nomenclature for the classification of buccinator myomucosal flaps, which clarifies the source vessel, the composition of the flap, and the type of transfer. RESULTS: According to this nomenclature, six types of buccinator myomucosal flaps are described. CONCLUSIONS: This proposed nomenclature may bring a consensus on the classification of buccinator myomucosal flaps and can help their spread.

Chimeric lateral supramalleolar artery perforator fibula free flap in the reconstruction of composite head and neck defects.

The authors evaluate the use of an osteomyocutaneous fibula free flap, combined in a chimeric fashion, with a lateral supramalleolar flap, in 10 patients with composite head and neck defects. All reconstructions were performed successfully. With the exception of one patient who died after disease recurrence, all patients were decannulated and resumed an oral diet. Speech intelligibility was good in seven of 10 patients. Dental implants were used in two of 10 patients, with a total of 10 fixtures placed successfully. The donor site healed without complications in all except one case, where necrosis of the skin graft occurred with fungal infection. The chimeric lateral supramalleolar artery perforator fibula free flap may be a valid option for maximizing the quality of life in patients with composite oromandibular defects.

Facial artery myomucosal free flap for cheek mucosa reconstruction: a case report.

Squamous cell carcinoma (SCC) of the buccal mucosa is an aggressive form of oral cancer. It tends to spread to adjacent tissues and often metastasizes to occult cervical node. There are multiple techniques for cheek reconstruction after tumor removal, including temporalis myocutaneous and temporoparietal fascial pedicled flaps and a forearm free flap. In this report, a case of a 76-year-old man with SCC of the left cheek mucosa and extending to the posterolateral superior alveolar ridge is presented. The patient underwent radical excision of the tumor, omolateral modified radical neck dissection (MRND-III), and contralateral selective neck dissection (levels I-III). Reconstruction was performed with a facial artery myomucosal free flap. The flap was transplanted successfully, and there were no donor or recipient site complications. This technique is a good reconstructive option because of its adherence to the plastic surgery principle of "replacing like with like" and its minimal donor-site morbidity.
