Zygomatic Implant

Zygomatic implant (ZI) is an option of the edentulism. Complications associated with ZI are maxillary sinusitis and soft tissue recession. The Zygoma Anatomy-Guided Approach (ZAGA), reduce the complications of the Original zygomatic intra-sinus Surgical technique (OI-ST). Study Aims: 1) report and compare the prevalence of sinus complications between ZAGA and OI-ST. 2) propose therapeutic guidelines for sinus. Material and Methods: ZAGA has been proposed to reduce the complications of the OI-ST. Results: Statistically significant increase of the "Modified Lund Mackay" (MLM) score (was noted in CT of patients after ZI surgery in comparison with the pre-surgical Lund-Mackay (LM) score (t=5, 0, p<.0005). Our study indicates that patients who underwent the ZI surgery according to the OI-ST. (M = 2.93, SD = 3.65) demonstrated a significantly higher ML-M score (t = 2.99, p < .003) compared to the patients operated with the ZAGA Concept (M = 1.52, SD = 2.36). Conclusions: ZI procedures can lead to sinus alterations. Significant differences have been found between two different approaches.

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 Introduction The study was conducted to asses if septoplasty is adequate for the management of chronic maxillary sinusitis. Chronic maxillary sinusitis is not uncommonly associated with deviated nasal septum (DNS). The randomized study was conducted on 40 cases of medically unmanageable and HRCT proven chronic maxillary sinusitis with DNS. Materials and methods The study was conducted in 40 cases of HRCT (PNS) proven chronic maxillary sinusitis which were not cured with medical treatment. The patients were divided randomly in two groups. Group A underwent septoplasty and group B septoplasty along with FESS in the form of uncinectomy and middle meatus antrostomy. Patients having other anatomical factors for example concha were excluded. Results Both procedures produced significant improvement in symptomatology and on HRCT (PNS) findings as compared to preoperative status (p-value less than 0.001). Septoplasty was found to be effective in chronic maxillary sinusitis, however, when polyps were present in maxillary sinus, then septoplasty with FESS was found to be better. Discussion In cases of chronic maxillary sinusitis with DNS, septoplasty is adequate, however if the maxillary sinus shows polyps on HRCT (PNS) scan then septoplasty should be combined with FESS.

Soft Tissue Masses

Solitary, benign soft tissue masses starting at the nasal cavity and extending to the nasopharynx are termed choanal polyps. They most frequently originate in the maxillary sinus and are termed antra-choanal polyp. Cases of CP originating in the upper concha are rather rare and only one case has been reported in literature in the English language to the best of our knowledge. This paper discusses a CP case originating in the upper concha, which was treated by endoscopic surgical technique, in the light of its clinical presentation and radiological findings.

SummaryAchilles mechanism rupture in four of five dogs was treated with tenorrhaphy using a modified surgical technique designed to optimise accurate apposition of tendon to bone. Two bone tunnels were drilled in the calcaneal tuber from a plantomedial - dorsolateral, and plantolateral – dorsomedial direction respectively. The distal ends of the tendons were sutured to the calcaneal tuber using a Krachow suture pattern. The remaining dog had a mid-tendon Achilles mechanism rupture. A resinous half cast was placed on the cranial aspect of the tarsocrural joint of all five dogs, for a minimum of six weeks, in order to provide limited post operative support. Du e to insufficient cast material two of the support splints failed and one of these cases also required a second surgical procedure. A varying amount of soft tissue irritation was noted in each case. All of the five Achilles mechanisms healed, and all of the dogs returned to normal function.Five dogs with surgical reconstruction of the Achilles mechanism were stabilised postoperatively with a resinous half cast placed on the cranial aspect of the tarsocrural joint for a minimum of six weeks. Two of these casts failed at the tarsocrural joint when six folds of casting material were used; all subsequent cases had eight folds applied. Variable soft tissue irration was observed under the cast in each case. A modified surgical technique using a Krachow suture pattern allowed good tendon-bone apposition. All five Achilles mechanisms healed, and all dogs returned to normal function. Bilateral lesions were identified in 3 of the 4 dogs examined.

Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening. The study sample consisted of 200 maxillary sinuses of 100 patients visible on CBCT examination with a field of view of 13 × 15 cm. The presented study revealed a significant influence of periapical lesions, inappropriate endodontic treatment, severe caries, and extracted teeth on the presence of increased thickening of maxillary sinus mucous membrane. In addition, an increase in the distance between root apices and maxillary sinus floor triggered a significant reduction of maxillary sinus mucous membrane thickening. The presence of periodontal bone loss significantly increases maxillary sinus mucous membrane thickening.

Posterior Area

Oro-antral communication (OAC) acts as a pathway for bacteria between the maxillary sinus and oral cavity, and is a common complication after the removal of a dental implant or extraction of a tooth from the maxillary posterior area. In the case of an untreated OAC, oro-antral fistula develops and becomes epithelialized. We aimed to introduce a treatment for OAC closure via a sinus bone grafting procedure using bone tacks and a collagen membrane with an allograft. The procedure was performed by applying an absorbable membrane made in pouch form. This membrane acted as a barrier for closing the large sinus membrane perforation. Bone tacks were used to fix the membranes. Subsequently, the maxillary sinus was filled with the allograft, and the absorbable membrane was reapplied. Primary closure was achieved by performing a periosteum-releasing incision for a tension-free suture. After 6 months, sufficient bone dimensions were gained without any occurrence of maxillary sinusitis or recurrence of OAC. Additional bone grafts and implantation could be performed to rehabilitate the maxillary posterior area. We conclude that this technique might be a useful treatment for reconstructing the maxillary posterior area with simultaneous sinus bone graft and OAC closure.

Abstract Background The presence of septa increases the risk of Schneiderian membrane perforation during sinus lift procedure, and therefore, the chance of graft failure increases. We present a safe method of managing septa and, in particular, overcoming small and palatally located septa. Methods After the elevation of the flap and the creation of a small bony window positioned anterior to the septum, the Schneiderian membrane is lifted carefully. A thin and narrow osteotome is then placed at the indentation created at the base of the septum, and mobilization of the septum is achieved by gentle malleting. The membrane is again carefully lifted up behind the septum. Results There was one small membrane perforation case in all 16 cases, and none of these patients showed postoperative complications such as implant failure, infection, or maxillary sinusitis. Conclusions This technique is useful for overcoming the problem of maxillary sinus septa hindering the sinus floor elevation procedure, leading to fewer complications.

In order to analyze whether ultrasonography with a reasonable degree of confidence can replace radiography in the diagnosis of sinusitis, 138 patients with clinical signs of sinusitis were examined with both methods. It was found that maxillary sinus fluid was recognized ultrasonographically with a confidence that increased with the amount of fluid, judged from radiographic examinations. In a sub-group of 45 cases, fluid confirmed by maxillary sinus puncture was detected by ultrasonography in 35/45 sinuses (78%) and by radiology in 38/45 sinuses (84%). In patients with radiographically normal maxillary sinuses, the correlation to ultrasound was good. However, mucosal swelling and polyps or cysts observed at radiography were poorly demonstrated by ultrasonography. In addition, the ultrasound method was not reliable for frontal sinus diagnosis. It was concluded that ultrasonography can be recommended in maxillary sinusitis for follow-up of treatment and as a screening method before sinus radiography.
