Special Issue Information

Dear Colleagues,

Traditionally, extensive bone grafting approaches have been considered as the gold standard for the rehabilitation of patients presenting extremely resorbed maxilla. For the last years, new approaches, new tools and new regenerative materials have been developed to improve the management and the outcomes for these challenging rehabilitations. A “patient-centric” perspective working toward an immediate normalization of quality of life seems to be the fundamental goal, with this being achieved by means of shortening the length and augmenting the predictability of the treatments.

The use of zygomatic implants, short implants, pterygoid implants, tilted implants or patient-specific implants (subperiostal implants) has undergone major developments. With the assistance of digital diagnostic and computer-aided surgery (static and dynamic) techniques, the accuracy of surgical performance and the outcomes could be improved in term of less risks and complications. The application of robotic surgery and Artificial Intelligence represent an emerging field that could lead to new advances and challenges.

This Special Issue searches for the current state and trends in the diagnosis and clinical management of the rehabilitation of extremely resorbed maxilla, in order to provide guidance and recommendations for clinical treatment.

Background/Objectives: There is a need for alternative approaches to full-arch rehabilitation of atrophic maxillae. The aim of this short case series was to describe the technique and assess the short term-outcomes of atrophic maxillae rehabilitation using transnasal implants in conjunction with zygomatic implants. Methods: Three female patients (average age: 62 years) presenting comorbidities and atrophic maxillae preventing the insertion of standard maxillary anchored implants received a full-arch fixed prosthesis supported by transnasal implants together with zygomatic implants, using the ad modum all-on-4 concept. Patients were followed during the functional osseointegration period. Primary outcome measures were prosthetic and implant survival based on function. Secondary outcome measures were complication parameters (biological and mechanical), plaque and bleeding levels, and probing pocket depths > 4 mm. Results: No implant failures were registered, and all prostheses remained in function. The only complication was a fracture of a provisional crown that was resolved. Plaque and bleeding scores were mild during the follow-up period. Conclusions: The present manuscript describes the use of extra-long transnasal implants in combination with zygomatic implants in immediate function for full-arch fixed prosthetic rehabilitation of atrophic maxillae, with the objective of promoting more research into this relatively recent technique. More studies are needed to validate the technique. Full article

Background: Assessing the morphology of the superior airway space is a crucial diagnostic step in the treatment planning of patients with obstructive sleep apnea syndrome (OSAS) or prior to orthognathic surgery. The aim of this study is to evaluate the necessary scope of a two-dimensional cephalometric assessment and the necessity of three-dimensional imaging in the identification of superior airway space narrowing (SASN). Methods: The computed tomography studies of 100 non-obese, non-OSAS patients were evaluated and analyzed retrospectively. Multiplanar reconstructions were created and underwent cephalometric evaluation. The three-dimensional superior airway morphology was segmented and measured for the minimal cross-sectional area (Amin) and volume (V0). Patients were grouped according to Amin < 80 mm2 and V0 < 12 cm3. Cephalometric parameters (CPs) were analyzed according to Amin and V0 with an unpaired t-test, Pearson correlation, and ROC-curve analysis. Results: The CPs regarding sagittal airway space dimensions (IPAS, MPAS, SPAS) and mandibular body length (GoGn) show the strongest correlation to the three-dimensional minimal cross-sectional area (Amin). The ROC-curve analysis classifying for SASN led to an AUC of 0.86 for IPAS, 0.87 for MPAS, 0.88 for SPAS, and 0.63 for GoGn. Three-dimensional imaging may further improve the diagnostic accuracy in the identification of SASN for IPAS below 13.5 mm, MPAS below 10.2 mm, SPAS below 12.5 mm, and GoGn below 90.2 mm. Conclusions: Two-dimensional cephalometric sagittal airway space diameters and mandibular body length are useful initial screening parameters in the identification of superior airway space narrowing. Nevertheless, as the correlation of two-dimensional cephalometric parameters with three-dimensional upper airway space narrowing is varying and highly dependent on acquisition circumstances, indications for three-dimensional imaging, if possible, in the supine position to evaluate upper airway space morphology should be provided generously, especially in patients with low but normal airway space parameters in two-dimensional cephalometry.

Background: Bleeding within the orbit in the form of a subperiosteal or retrobulbar hematoma is a relatively common complication of trauma and surgery. It affects up to 30% of patients fractures involving the orbital bones. Most cases do not require surgical intervention because they do not cause retinal ischemia or optic nerve neuropathy. The above symptoms occur in only 0.5–1% of patients developing Orbital Compartment Syndrome (OCS). Due to the short period (60–100 min) of time in which the optic nerve and retina can tolerate increased intraocular pressure, it seemed reasonable to evaluate and standardize the surgical management protocol for this rare complication. Objective: The aim of this retrospective study was to retrospectively analyze cases of inframammary haematomas with clinically relevant correlations. Methods: Eighteen patients treated at the Department of Maxillofacial Surgery due to OCS, in Lodz and Poznan, Poland, between 2009 and 2022, were included. APTT, INR, systemic diseases, cause, location and size of hematoma, presence and number of fractures, visual disturbances and pupillary response on the day after surgery and one month after, the type of intervention and time between admission to the hospital and surgery were evaluated. Results: Statistically significant correlations were obtained between the size of the hematoma and the patients’ age, the degree of visual disturbance and the weakening of pupillary constriction, severe initial symptoms and poor postoperative outcomes at both postoperative periods studied, immediate and distant poor outcome after decompression surgery and good postoperative outcome persisting one month after. Conclusions: The results obtained in the study and the surgical protocol proposed by the authors are in line with the current state of knowledge regarding orbital hematomas. Some of the correlations described in the literature (such as OCS and anticoagulant treatment) were not demonstrated, but this is probably due to the small study group. Maintaining the 100 min limit as a standard was possible only in early postoperative diagnoses (only 1 of the patients was operated on up to 100 min after the appearance of symptoms). In other cases, the specialized diagnosis took an average of 2785 ± 4020 min or 46 ± 67 h. Full article
