Favorable OHRQoL and satisfaction were reported after advanced reconstruction with iliac crest-derived grafts and implant treatment in orally compromised patients. However, this treatment requires substantial resources including hospitalization and sick leave.

Discussion : Patient experience following iliac cr...

Patients in our study reported satisfaction with the augmentation and implant installation, and as these patients were orally compromised before the operation, their satisfaction with getting fixed teeth most likely improved their perceived oral health condition. This might also, in part, explain why they reported good OHRQoL. Thus, our findings indicate that a majority of patients tolerate the au...

Discussion : Patient experience following iliac cr...

An important finding in this study is that a majority of patients were very satisfied after iliac crest-derived alveolar bone grafting and implant therapy. Although 90% of the patients in our study had successful bone grafting, only 70.1% reported implant survival together with prosthetic rehabilitation after 1 year. These figures are lower than those reported in previous studies [2, 3, 9]. A rev...

The correlation analyses performed did not show a significant correlation between the complications at the donor site and implant loss (Table 4). The mean OHIP-14 score (Table 5) was 8.4 ± 9.7 (range 0–56) in 44 patients of whom 35 patients scored 14 or less. Nine patients scored a total sum of 1 [1], i.e. “hardly ever” impact on any single item and “at no time” on the remaining ...

The final sample consisted of 44 patients that responded and completed the questionnaire, giving a response rate of 74.6%: 24 women and 20 men, mean age of 61.2 years ± 13.1 (range 27–82 years).

Background : Patient experience following iliac cr...

Health-related QoL (HRQoL) is a dynamic concept referring to an individual’s subjective assessment and perspective of current general health condition as well as functional, social, and emotional well-being [23, 24]. Most people regard oral health as important for QoL, and this is mediated through the concept of oral health-related QoL (OHRQoL) [25]. In this regard, OHRQoL is an important PROM i...

Background : Patient experience following iliac cr...

Insufficient alveolar bone volume, as a result of periodontal disease, trauma, congenital anomalies and/or resorption atrophy, often presents a clinical challenge for optimal placement of dental implants for prosthetic rehabilitation. In such cases, augmentation of alveolar bone, with either autologous bone, allogeneic, xenogeneic, or alloplastic biomaterials, is a prerequisite for placing implant...

The objective of this study was to assess patient-reported outcomes such as satisfaction and quality of life after advanced alveolar bone augmentation with anterior iliac crest grafting and implant treatment in orally compromised patients.

The ZIP flap technique represents an innovative approach to the management of patients presenting with low-level malignant maxillary tumours.

Whilst technically, it would be possible to construct and fit the prosthesis on the same day or even a week later, the need for microvascular flap monitoring in the immediate post-operative period, together with the significant recovery period required by the patient following surgery has lead the authors to delay the fitting of the prosthesis at the 4 to 6-week period post-operatively. In terms o...

In contrast, the use of a soft tissue flap such as the RFFF or antero-lateral thigh flap can often be safely employed in elderly patients with peripheral vascular disease without unduly lengthening the operation too significantly with two-team operating. In addition, the predictability of these flaps with their excellent pedicle lengths is ideal for closure of the resulting oro-nasal surgical defe...

In low-level maxillectomy (Brown class II), the need for bony reconstruction is questionable depending on the horizontal component. With the preservation of the orbital floor, zygomatic prominence and some bony support for the nose, facial appearance, in the experience of the authors and, as demonstrated by this case, is not significantly worsened despite low-level removal of the maxilla. The key ...

In order to address some of the issues highlighted in this early case, the technique was modified slightly to try and prevent flap overgrowth and prosthesis fracture in the early stages. In order to prevent flap overgrowth over the zygomatic oncology implant abutments, the use of a polythene washer was instituted on subsequent cases treated in the unit. Once the flap was perforated, a 2-mm thick p...

The implant positions were then accurately registered by utilising light-cured resin tray material (Individo® Lux, Voco Gmbh, Germany) and abutment level impression copings. The resin material was applied in sections around the impression copings and cured incrementally to ensure a rigid splinting of the impression copings (Fig. 8).

The surgical management and prosthodontic rehabilitation of the maxillectomy patient is complex with a variety of options available to the head and neck cancer team ranging from simple prosthodontic obturation [1] to reconstruction using pre-fabricated or digitally planned composite flaps [2] with or without the placement of osseointegrated implants [3]. The primary aims of treatment include effec...

This aim of this report is to describe the development and evolution of a new surgical technique for the immediate surgical reconstruction and rapid post-operative prosthodontic rehabilitation with a fixed dental prosthesis following low-level maxillectomy for malignant disease. The technique involves the use of a zygomatic oncology implant perforated micro-vascular soft tissue flap (ZIP flap) fo...

Conclusions: The zygomatic implant perforated (ZIP...

Conclusions The ZIP flap technique represents an innovative approach to the management of patients presenting with low-level malignant maxillary tumours. It provides effective closure of the resulting maxillary defect restoring speech and swallowing functions and also establishing a high-quality fixed dental rehabilitation in a rapid timescale, thus facilitating a more timely return to function...

Discussion: The zygomatic implant perforated (ZIP)...

Immediate/early loading of zygomatic [8] and dental implants [9] have been well demonstrated already within the literature with very high implant survival rates. In the oncology setting, Boyes-Varley et al. [4] lost no zygomatic/oncology implants in their series of 20 patients restored with implant-retained obturators, 6 of whom received radiotherapy post-operatively. The case reported...

Discussion: The zygomatic implant perforated (ZIP)...

The use of soft tissue flaps to close a typical hemi-maxillectomy defect is an effective way of dealing with the oro-nasal communication, but in isolation, this technique works against dental rehabilitation as the bulk of the flap provides a very poor moveable foundation for a subsequent removable prosthesis. The move towards the use of composite reconstruction (especially the fibula flap) h...

Discussion: The zygomatic implant perforated (ZIP)...

Discussion In order to reduce intra-operative time, the soft tissue free flap is harvested at the same time as the implant placement and prosthodontic procedures. On raising a skin island, it is appropriate to make it a little over-sized for the required defect to ensure that tension and possible dehiscence at the surgical margins during healing is reduced. In low-level maxillectomy (Brown...

Procedural modifications to the ZIP flap technique

Procedural modifications to the ZIP flap technique In order to address some of the issues highlighted in this early case, the technique was modified slightly to try and prevent flap overgrowth and prosthesis fracture in the early stages. In order to prevent flap overgrowth over the zygomatic oncology implant abutments, the use of a polythene washer was instituted on subsequent cases treated in th...

The ZIP flap technique (2)

The radial forearm free flap (RFFF) was then disconnected from the arm and inset into the maxillary defect after creating a tunnel down into the left neck for the pedicle. The flap was carefully perforated over the zygomatic implant abutment protection caps using a short incision just through the skin layer followed by blunt dissection to allow the abutment and cap to perforate the flap ensuring a...

The ZIP flap technique (1)

The ZIP flap technique The patient underwent tracheostomy, a limited left-sided selective neck dissection for node sampling and vessels preparation. The maxillary tumour was excised in a standard manner via an intra-oral approach with preservation of the left orbital floor (Fig. 5). The resection extended to the maxillary alveolar midline in the incisor region with extension posteriorly just into...

Case : The zygomatic implant perforated (ZIP) flap

Case presentation A 66-year-old male patient presented with an enlarging mass in the left maxilla (Fig. 1). The mass had been present for a few weeks. An incisional biopsy revealed squamous cell carcinoma. Staging scans were undertaken (Fig. 2) which demonstrated a T4N0M0 maxillary alveolus tumour in close proximity to the left orbital floor with obliteration of the maxillary antrum and destruc...
