Purpose: To present a case series of zygomatic implants combined with bone regeneration and soft tissue enhancement techniques to reduce the risk of biological delayed complications such as maxillary sinusitis and soft tissue recession. Materials and methods: Zygomatic implants placed simultaneously with different bone regeneration techniques (buccal, palatal and buccal-palatal bone regeneration) and soft tissue enhancement techniques (pediculate and free connective tissue graft) were followed for at least 12 months. The following information was collected: patient age and sex, number of zygomatic implants, zygomatic implant success rate, zygomatic implant position according to classification of the Zygomatic Anatomy Guide Approach (ZAGA), sinus membrane perforation, type and outcome of the bone regeneration or the soft tissue enhancement technique, bone gain (width and length along the zygomatic implant) and keratinized buccal mucosa width, duration of follow-up, loading protocol (immediate or delayed) and biological complications (maxillary sinusitis and soft tissue recession). Results: Thirty-one zygomatic implants placed in 19 patients were included. All implants were successful and none of the implants presented biological complications. The bone regeneration technique was successful in 30 of 31 cases with a mean palatal bone width of 3 mm, buccal bone width of 2.65 mm, palatal bone length of 6.5 mm and buccal bone length of 8.3 mm. The success rate of soft tissue enhancement was 100% and it established at least 2 mm of keratinized buccal mucosa width in all implants. Conclusions: Within the limitations of the present study, bone regeneration and soft tissue enhancement techniques were useful to establish more favorable conditions of the peri-implant tissues around zygomatic implants. This could prevent biological complications such as maxillary sinusitis and soft tissue recessions. Prospective and randomized controlled clinical trials with longer follow-up periods are advisable.

Abstract Background: The aim of this study was to evaluate the clinical outcome of autotransplantation of mature third molars to fresh molar extraction sockets using 3D replicas. Methods: Ten patients underwent teeth autotransplantation with or without GBR. We observed the mobility, percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth during two years following up, which were transplanted into fresh molar sockets by using 3D replicas, and GBR when it is necessary. Results: The average extra-oral time of donor tooth had been shortened to 1.65 min when used the 3D replica. Some probing depth of the transplanted tooth were deeper than 3 mm at 4 or 5 weeks temporarily. And one patient felt slight sensitive when chewing with soft food at 4 weeks, then disappeared. The clinical examination of the autotransplantation teeth during one year follow-up showed no sign of failure. Conclusions: The tooth autotransplantation using 3D replica with or without GBR is an effective method which can reduce the extra-oral time of the donor teeth and may result in less failure.

Objective: Impingement syndromes are recognized as an important cause of chronic ankle pain, which results from the entrapment of an inflamed soft-tissue component between the osteophytes. The predominant site of occurrence is the anterolateral aspect of the ankle for soft-tissue impingement, and anteromedial aspect for bony impingement. Symptoms related to the physical impact of bone or soft-tissue pain often result in limited ankle range of motion. Methods: We conducted a retrospective study of 34 patients (34 ankles) with anteromedial bony impingement. All patients underwent arthroscopy, with a mean follow-up of 34 months. Results: All osteophytes were removed, and the ankle range of motion improved. The AOFAS score improved from 73 preoperatively to 95 postoperatively. Conclusion: The arthroscopic removal of the anteromedial osteophytes of the ankle had excellent functional results. It is an effective procedure that allows rapid patient recovery.

Background and objectives: Closed reduction and short leg spica casting are the preferred treatment options for children with developmental dysplasia of the hip. This study aimed to show the efficacy behind a standardized closed reduction for managing patients with developmental dysplasia of the hip with concomitant soft tissue releases when indicated and using a short leg plaster of Paris cast to maintain reduction and reporting mid-term results. Methods: A case series of 95 hips in 84 children aged 6-18 months who had closed reduction, with five years follow up or until next operation, involved in this study. The protocol defines acceptable concentric reduction criteria and the indications for an associated soft tissue release. All the patients were immobilized in a short leg cast for three months. Multiple follow-up radiographs were taken to assess Tönnis grade, Severin grade, acetabular index, and osteonecrosis signs. Results: A total of 48 hips were Tönnis grade 3/4 hips. At one year, 15 reductions couldn’t be maintained, and these patients needed open reduction. Of these 15 failed reductions, 7 patients were Severin 1; others were Severin 2. Of the 80 successful closed reductions, 70 hips were Severin 1. Surgical management for residual dysplasia was offered for 8 hips. Osteonecrosis was seen in 23 hips but was transient in 20. Bilateral hip dislocations and most Tönnis 4 hips were more likely to fail. Two children had severe osteonecrosis. Conclusions: Closed reduction, with subsequent adductor and psoas releases, when indicated and using a short leg plaster of Paris cast for three months, brings about good mid-term results in children with developmental dysplasia of the hip aged 6-18 months. Keywords: Developmental dysplasia of the hip, closed hip reduction, open psoas release, short leg cast.

Edentulous patients with an atrophic maxilla associated with lip-palate fissures have unpredictable results after undergoing grafting procedures. In situations where the atrophic maxilla does not adequately allow reconstruction, the use of zygomatic implants has been indicated, and probably these implants can be indicated for the rehabilitation of patients with lip-palate fissures. This case report describes the oral rehabilitation treatment of a patient with a lip-palate cleft treated with zygomatic implants and implant-supported fixed prosthesis with two years of follow-up. A 65-year-old female patient had a lip-palate cleft and previously underwent surgery to close the cleft. The patient had a severely atrophic maxilla and had difficulty adapting to a removable total prosthesis. Due to the small amount of bone remaining and extensive fibrous tissue in the palate region, a rehabilitation with conventional implants associated with zygomatic implants was chosen. Two zygomatic implants and a conventional implant were placed on the right side, and a zygomatic implant and conventional implant were placed on the left side; these implants were later activated by a protocol-type prosthesis. The zygomatic implants provided an adequate aesthetic and functional outcome of the prosthesis in a patient with cleft palate.

Objectives We determined the effectiveness of calcium hydroxylapatite (CaHA) paste in vocal rehabilitation. Methods We examined a retrospective case series of 39 adult patients who underwent CaHA paste injection for vocal fold rehabilitation over a 5-year period. The outcomes included the change in the Voice Handicap Index (VHI) score; procedure-related complications; and the need for follow-up voice procedures. Results The VHI scores demonstrated overall improvement, with a decrease from the preoperative mean of 61.2 ± 24.0 to a postoperative mean of 35.9 ± 26.3 (p = 0.0001) after a mean follow-up time of 17.8 ± 13.6 months. The procedure was more likely to succeed in patients with paralysis and/or paresis than in patients with glottic soft tissue defects. After injection, the VHI scores worsened in 3 of 7 patients (43%) in the soft tissue defect group, compared to only 2 of 28 (7%) in the paralysis and/or paresis group (p = 0.04). Four of 7 patients with soft tissue defects (57%) required secondary vocal procedures to improve the voice, compared to only 2 of 32 (6%) in the paralysis and/or paresis group (p = 0.006). Conclusions Injection of CaHA paste results in significantly improved vocal scores in the majority of patients. Use of the paste was less satisfactory in patients with soft tissue defects because of poor retention of the paste in the scarred vocal fold remnant.

This case report presents a treatment of peri-implantitis associated with a pre-existing pathology. Peri-implantitis around implant #19 was detected from pus discharge upon probing. Guided bone regeneration was performed to treat the peri-implantitis with the administration of antibiotics. The histopathologic evaluation of soft tissue taken from the circumferential defect around the implant exhibited a cyst. The postsurgical CBCT and the follow-up radiograph confirmed the maturing bone graft and a reduced size of the defect around the implant.

To present our experience of removing middle to deep orbital tumors using a combination of minimally invasive soft tissue approaches, sometimes under local anesthesia.Methods.In this retrospective case series, 30 patients (13 males and 17 females) underwent tumor removal through eyelid crease (17 eyes), conjunctival (nine eyes), lateral canthal (two eyes), and transcaruncular (two eyes) approaches. All tumors were located in the posterior half of the orbit. Six cases were removed under monitored anesthesia care with local block, and 24 were under general anesthesia.Results.The median (range) age and follow-up duration were 48.5 (31–87) years old and 24.5 (4–375) weeks, respectively. Visual acuity and ocular motility showed improvement or no significant change in all but one patient at the latest followup. Confirmed pathologies revealed cavernous hemangioma (15 cases), pleomorphic adenoma (5 cases), solitary fibrous tumor (4 cases), neurofibroma (2 cases), schwannoma (2 cases), and orbital varix (1 case). None of the patients experienced recurrence.Conclusions.Creating a bony marginotomy increases intraoperative exposure of the deep orbit but adds substantial time and morbidity. Benign orbital tumors can often be removed safely through small soft-tissue incisions, without bone removal and under local anesthesia.

This report retrospectively at the 12-year follow-up results of the treatment and rehabilitation of edentulous maxillae, applying extra-sinus zygomatic implants alone or in combination with intra-sinus zygomatic implants. We recruited 22 patients with 35 zygomatic Brånemark system implants; 24 implants in the standard Brånemark protocol through the sinus and 11 extra-sinus implants outside the sinus. Additionally, 147 regular implants were placed. The minimum follow-up period was 50 months to a maximum of 152 months. The zygoma survival rate after 12 years was 97.15%. Chronic sinusitis occurred in 11.42% of patients. We lost 1 (2.85%) zygomatic implant placed through the sinus and none of those in the extra-sinus position. The survival rate of the regular implants was 93.87%. Chronic sinusitis occurred in 4 patients (11.42%) who received zygomatic implants using standard protocol through the sinus. None of the extra-sinus zygoma patients developed sinusitis. Peri-implantitis was detected with only 3 zygomatic implants. In the original P-I Brånemark zygoma protocol the implants were passing through the sinus, which resulted in chronic sinusitis in some patients and malposition of the prosthetic platform toward the palate. These complications can be avoided by the extra-sinus placement of zygoma implants as demonstrated in this study.
