Introduction. Orofacial reconstruction plays an important role in the treatment of patients affected by oral and maxillofacial cancers. Improvements in technologies and studies of biomaterials have widely expanded surgical possibilities to achieve good functional and aesthetic outcomes. By the way, xenografting procedures gained great consensus in the last decades, because of their documented reliability and efficacy. We present a case of anterior maxillary chondrosarcoma (CHS) that has undergone surgical ablation followed by reconstruction with an equine-derived bone xenograft. Case Presentation. A 68-year-old woman affected by CHS of the premaxilla underwent surgical ablation involving the four incisors followed by reconstruction using an equine-derived bone substitute. Bony reconstruction was planned to achieve implant and dental prosthetic rehabilitation at a second surgical time. Primary surgery was carried out without complications. Good integration of the graft was confirmed by radiological examination. At 12-month follow-up, the patient refused the implant placement and spontaneously adopted a mobile prosthesis. One year later, plates and screws were removed, because of the exposure of a titanium plate. The graft was finally rejected within 3 weeks. Discussion. Nonantigenic equine-derived biomaterials have shown reliability and a good safety profile. In the presented case, implant insertion should have been performed 12 months after the primary surgery. During the follow-up, until dental mobile prosthesis was applied, clinical and instrumental examinations demonstrated a good integration of the graft. We suppose that a chronic inflammation of the mucosa led to the exposure of the plate, perhaps due to pressure, minimal movements, or imperfect fitting of the mobile prosthesis. Removal of fixation means was performed to prevent grafting failure, without success. On the other hand, missing load could induce the graft to act just like a prosthesis, without a real process of integration. Safety and reliability of equine-derived bone xenografts cannot be currently confirmed if not followed by implant insertion and dental rehabilitation.

Abstract Background Mucormycosis is a rare fungal infection occurring chiefly in the lung or the rhino-orbital-cerebral compartment, particularly in patients with immunodeficiency or diabetes mellitus. Among Mucorales fungi, Rhizopus spp. are the most common cause of mucormycosis. Case presentation We report a case of pulmonary mucormycosis caused by Rhizopus microsporus in a young patient with diabetes but no other apparent risk factors. The diagnosis mainly relied on clinical manifestation, positive pulmonary tissue biopsy, and fungal culture. The patient was successfully treated with posaconazole oral suspension and remains asymptomatic at one-year follow-up. Conclusions Pulmonary mucormycosis is a life-threatening condition and posaconazole is an effective treatment for pulmonary mucormycosis caused by Rhizopus microspores.

Molar Extraction

The placement of immediate implants in the posterior sector is a widespread procedure where the success and survival rates are similar to those of traditional protocols. It has several anatomical challenges, such as the presence of interradicular bone septa that hinder a correct three-dimensional positioning of the implant and may compromise primary stability and/or cause damage of neighboring structures. The aim of this article is to present the treatment and the one-year clinical follow-up of a patient who received immediate implant placement using an interradicular bone-drilling technique before the molar extraction.

This clinical case describes the effect of the osteotome technique on the osseointegration of a mandibular dental implant in a 42-year-old female patient with dento-alveolar bony defects and to review the literature regarding immediate implant placement using osteotome technique. The amount of bone expansion at the alveolar ridge and the marginal bone resorption from the time of implant placement to one year after the implant’s functional loading were recorded clinically. The esthetic outcome for the restored implant (the gingival margin) was achieved one years after the implant’s functional loading. The surgical and prosthetic sites for the implant showed no postoperative complications, and no infection or wound dehiscence was recorded during the follow-up period. The osteotome technique is good for the purpose for which it was introduced, and its advantages with immediate implant placement include reduced surgical trauma and a shorter treatment time.

In this paper, we present a simple way to place the implant into a harvested pocket and to subsequently fix it percutaneously. Eighteen patients (1 male, 13 females, 4 transgender), underwent facial implant placement; a total of 31 implants were placed (1 pair of angles of the mandible implants, 12 pairs of malar/sub-malar implants, and 5 chin implants). The intraoral approach was performed on 15 patients, and on the remaining three patients, the sub-ciliary lower lid approach was preferred. Patients were followed up for at least one year with a maximum follow-up of seven years (mean 1.8 years). In all the cases, except one, patients healed without complications. One case of implant displacement and infection was recorded. No other complication was documented. The technique described is similar to the one suggested by Peled, although some useful tips were added, namely the use of sutures, not only to fix the implant but also to drive it into the harvested pocket. In addition, larger absorbable “left in place” sutures were used, avoiding accidental implant dislocation during their removal. Further studies are required to gain a more complete understanding of the effectiveness and reproducibility of this surgical technique.

Introduction. Late-onset bleb leaks occur more frequently after the use of adjunctive antimetabolites and require surgical management to seal and preserve filtrating bleb.Case Presentation. A 48-year-old female presented with decreased visual acuity for five days in her left eye. She had a left penetrating keratoplasty one year earlier and two trabeculectomies 7 years earlier. Visual acuity was hand motions, intraocular pressure was 3 mmHg, corneal graft was clear, mature cataract was present, and axial length was 30.48 mm. The conjunctiva covering the superotemporal sclerotomy was avascular, flat, and partially lost. After heavily painting the bleb with a fluorescein, late-onset point leak was revealed. Overlying conjunctiva was excised. The atrophic, irregular, and partially absent scleral flap was covered by a processed human pericardium graft and conjunctival advancement. Postoperatively, intraocular pressure stabilized around 16 mmHg. After four months, phacoemulsification and intraocular lens implantation were performed. Visual acuity did not exceed 0.1 (in decimal notation) due to degenerative myopia-related macular atrophy. Corneal graft remained clear at her 6-month followup period.Conclusion. Surgical bleb revision using a pericardium graft and conjunctival advancement seems to be an effective method for treating late bleb leaks. However, careful follow-up is required for detecting recurrent leaks and elevated intraocular pressure.

Abstract Objectives: This study evaluated the use of bone ring technique with xenogeneic bone grafts in treating horizontal alveolar bone defects. Material and methods: In total, 11 patients in need of horizontal bone augmentation treatment before implant placement were included in this retrospective study. All patients received simultaneous bone augmentation surgery and implant placement with xenogeneic bone ring grafts. We evaluated the postoperative efficacy of the bone ring technique with xenogeneic bone grafts using radiographical and clinical parameters. Results: Survival rates of implants were 100%. Cone-beam computed tomography revealed that the xenogeneic bone ring graft had significantly sufficient horizontal bone augmentation below the implant neck platform to 0 mm, 1mm, 2mm, and 3mm. It could also provide an excellent peri-implant tissue condition during the one-year follow-up after loading. Conclusion: The bone ring technique with xenogeneic bone ring graft could increase and maintain horizontal bone mass in the region of the implant neck platforms in serious horizontal bone defects.

Objective: With the introduction of endovenous treatments, open varicose veins surgery was discarded due to a claimed high risk of neovascularisation. A one-year audit was set up to look at results from performing mainly open surgery. Methods: All varicose vein interventions were registered and prospectively followed with colour Duplex assessments after 4-6 weeks, 1 and >5 years. In addition, Aberdeen Varicose Vein Questionnaire (AVVQ) was used in addition to Varicose Vein Severity Score (VCSS) to assess patients’ quality of life (QoL) and the disease severity. Results: During the year, 236 patients/252 legs were operated and 28% were re-do procedures. Median age was 55 years (16-87) and 70% were females. Duplex at 4-6 weeks showed a primary success rate of 91%. Neovascularisation was noted in 8% one year after primary surgery. The long-term assessment was done after a median of 69 months (39-75) and 67% of all legs were examined. After primary surgery 16% showed neovascularisation compared with and 27% after re-do procedures. VCSS improved significantly from 6 (range 1-22) to 2 at the long-term follow-up (p<0.001). The AVVQ score improved from 20 (range 3-55) down to 10 (p<0.001). Conclusion: The risk for neovascularisation seems to have been overestimated and good long-term results can be achieved following modern open surgery. The major problem is to avoid varicose vein recurrence since results from re-do procedures seem less favourable long term.
