CO(2) laser endoscopic surgery is effective in the treatment of glottic carcinoma not infiltrating the cartilaginous skeleton; the results achieved are competitive with those of open conservative operations, if we take into account the possibilities afforded by salvage surgery and the rate of laryngeal preservation achieved in the study patients.

It is reasonable to affirm that the major cause of displacement of implants is related, most of the time, to incorrect treatment planning and/or a poorly performed surgical procedure. When implant displacement occurs, the displaced foreign body has to be removed in order to avoid sinus pathology.

Maxillofacial departments in 23 surgical units in Italy have been increasingly involved in facing the COVID-19 emergency. Elective surgeries have been progressively postponed to free up beds and offer human and material resources to those infected. We compiled an inventory of 32 questions to evaluate the impact of the SARS-COV2 epidemic on maxillofacial surgery in 23 selected Italian maxillofacial departments. The questionnaire focused on three different aspects: the variation of the workload, showing both a reduction of the number of team members

Background:Tongue squamous cell carcinoma (TSCC) is increasing in incidence, especially among young patients and preferably females. Infection with human papilloma virus (HPV) has been suggested as a cause of SCC in the head and neck, and the proportion of oropharyngeal cancers caused by HPV has steadily increased.Methods:Samples from 109 patients with primary TSCC were analysed for the presence of HPV16 by in situ hybridisation and for expression of its surrogate marker p16 and the HPV receptor syndecan-1 by immunhistochemistry.Results:No evidence of HPV16 DNA was observed in the tumours, although one-third showed p16 staining. There was no difference in the expression of the primary HPV receptor, syndecan-1, between TSCC and a group of tonsil SCC.Conclusion:Whereas p16 is expressed in some TSCCs, HPV16 is undetectable, therefore, p16 cannot be used as a surrogate marker for high-risk HPV-infection in this tumour. Despite presence of the HPV-receptor syndecan-1 in TSCC, HPV prefers the tonsillar environment. Lack of p16 associates with worse prognosis primarily in patients aged ⩽40 years with tongue SCC. The improved prognosis seen in p16-positive TSCC can be due to induction of a senescent phenotype or an inherent radiosensitivity due to the ability of p16 to inhibit homologous recombination repair.

Introduction Orthognathic surgery involves making several osteotomies that lead to varying degrees of post-operative swelling. The use of KT may be beneficial for postoperative treatment after head and neck surgery, accelerating drainage of tissue reaction or haemorrhages. The goal of this study was to find out if the application of KT prevents or improves swelling, pain and trismus after orthognathic surgery, improving patients' postoperative quality of life. Materials and Methods In this double-blinded, randomized, control trial, 24 patients in whom bimaxillary orthognathic surgery was indicated, were included. Before surgery each patient alternatively was randomly included in the study group (treated with K-Taping Ò and corticosteroid) or in the control group (treated with corticosteroid). In the present study a MakerBot Ò Digitizer 3D TM was used to assess accurate volume measurements. All swelling measurements were expressed as total 3-D area of the landmarks (cm 2 ) in T0 pre-operative, T1 fourth day after surgery. Results The differences T0-T1 are highly significant (p \ 0.01) between group 1 or study group (treated with K-taping Ò ) and group 2 (control group). Discussion The use of KT appears promising, because it is simple to carry out, less traumatic, economical, can be performed everywhere in the world, free from side effects on the body. Even when swelling persists, KT gives patients the impression of a minor swelling detracting them from their pain and morbidity. Further studies have to be performed to find out if KT can reduce or replace the need for additional medications such as the use of steroids.

Restoration of the edentulous alveolar ridge with implants often requires the ridge width to be augmented to allow its placement. The aim of this study was to evaluate the split-crest technique, with subepithelial connective tissue graft used as biological barrier, in patients with narrow ridges, focusing on the status of soft and hard tissues and on implant success rate, at 36 months after implant loading. Thirteen patients (6 males and 7 females), ages 32-68 years (mean 49.4 years) with an atrophic maxillary jaw underwent modified edentulous ridge expansion technique for implant placement. A total of 33 Laser-Lok tapered internal implant, were placed in the maxilla. The following parameters were evaluated: (1) initial ridge width (time t0); (2) ridge width at the time of abutment connection (time t1); four months after implants placement, healing abutments were connected and the prosthetic rehabilitation was initiated, and all patients were evaluated clinically and radiographically with periapical radiograph at intervals of 3-6 months for the first year and annually thereafter for 3 years. The ridge width was measured with a cone beam computed tomography. The initial ridge width ranged from 3.5 mm to 7 mm (mean: 4.67 mm), while at the end of the expansion procedure the width ranged from 6.3 mm to 11.0 mm (mean: 8.2 mm). The width gain of the edentulous ridge ranged from 1.45-4.9 mm (mean: 3.5 mm). Two implants became exposed 1 month after surgery. One implant was lost before loading (3%). The diameter of failed implant was 5.8 mm and length was 10.5 mm. The remaining 32 implants were stable and free of complications at the end of the study. Thus, the implant survival rate was 97%. Because no implant failed after loading, the cumulative survival rate of loaded implants was 100%. The minimally invasive regenerative technique presented here avoids the use of bone graft, secondary surgery for soft tissue augmentation, and mechanical expansion devices. However, the follow-up period for outcome evaluation and exiguous patient's number in this series was limited.
