BACKGROUND: This study investigates maxillofacial fractures in non-indigenous ethnic groups who were reviewed in the national maxillofacial unit in Ireland. The aim of this study was to highlight any potential trends in presentation of facial fractures in non-indigenous groups in comparison to previous reports which have included all ethnicities. This unique study is based on the fact that Ireland has only recently transformed into a diverse, multi-cultural country. This is unlike countries such as the UK and USA which have a long history of multicultural integration...

Kabuki syndrome (KS) is a rare congenital disorder with distinctive characteristics. Herein, we describe a KS patient carrying a novel mutation in the KMT2D gene, c.11785C > T (p.Gln3929*). The patient presented with typical eyelid deformities, including eversion of the lateral lower eyelids, long palpebral fissures, hypertelorism, and medial epicanthus. Orbital computed tomography revealed orbital bone malformation with temporally and inferiorly displaced zygomatic bone. The bilateral orbits were shallow with an enlarged angle between the lateral walls...

OBJECTIVE: To study the microanatomic structure of the subtemporal transtentorial approach to the lateral side of the brainstem, and to provide anatomical information that will assist clinicians to perform surgeries on the lateral, circumferential, and petroclival regions of the brainstem. METHODS: Anatomical investigations were conducted on 8 cadaveric head specimens (16 sides) using the infratemporal transtentorial approach. The heads were tilted to one side, with the zygomatic arch at its highest point...

Leiomyoma is the most prevalent benign tumor of the female reproductive system. Benign metastasizing leiomyoma (BML) is a rare phenomenon that presents at distant sites, typically the lungs, exhibiting histopathological features similar to the primary uterine tumor in the absence of malignancy features in both. Fumarate hydratase-deficient uterine leiomyoma (FH-d UL) is an uncommon subtype among uterine smooth muscle tumors (0.5-2%), showing distinctive histomorphology and FH inactivation. The majority of FH-d ULs are sporadic, caused by somatic FH inactivation, while a minority of cases occur in the context of the hereditary leiomyomatosis and renal cell carcinoma (HLRCC) syndrome caused by germline FH inactivation...

OBJECTIVE: The study's purpose was to compare the quality of life (QoL) in oncologic patients treated with different rehabilitation protocols following maxillary tumor resections. PATIENTS AND METHODS: The patients were divided into three groups. Group A: 18 Patients with maxillary obturator prosthesis. Group B: 17 Patients with simultaneous autologous tissue reconstruction. Group C: 12 Patients with prosthesis on zygomatic implants. The post-operative QoL was compared using standard questionnaires, investigating items like pain, mood, social relations, and specific functions that could potentially compromise the post-operative QoL...

Patients with facial trauma often experience a psychological burden from their injuries. This study aimed to identify risk factors for adverse mental health outcomes in patients affected by facial trauma, using the 'Integrating Mental and Physical Healthcare: Research, Training and Services' (IMPARTS) screening tool. All patients >18 years of age who completed more than one IMPARTS screening tool in the Oral and Maxillofacial Trauma Clinic between 2019 and 2021 were included in this study. This tool was used to assess the risk of post-traumatic stress disorder (PTSD), generalized anxiety disorder, and depression...

Knowledge of the structure of the face is of fundamental importance. In fact, the face is treated in many areas of medicine, from dermatology, to maxillofacial surgery, to otorhinolaryngology, to ophthalmology, etc. and anti-aging aesthetic treatments, and those for the resolution of blemishes are on the increase. For ethical reasons it is not possible to take biopsy samples for facial analysis in the aesthetic field. The main aim of this study was to demonstrate that a high-resolution bimodal ultrasound examination, combined with elastosonography, could be a valid tool for pre-treatment morphological evaluation...

BACKGROUND: It is now possible to predictably distalize maxillary first molars in nongrowing patients with the infra-zygomatic gear distalizer and to improve malocclusions without having to extract the premolars and regardless of the patient's compliance. The purpose of this study was to investigate the amount and rate of distal movement of the maxillary first molars using our proposed appliance after extraction of maxillary second molars. METHODS: Ten nongrowing female patients successfully treated with our proposed appliance were the subjects of this study...

STATEMENT OF PROBLEM: Dynamic computer-assisted zygomatic implant surgery (dCAZIS) has been reported to provide clinical efficacy with high accuracy and low risk of complications. However, the learning curve before performing dCAZIS effectively is unknown. PURPOSE: The purpose of this in vitro study was to explore the learning curve of dCAZIS in dentists with different levels of experience in implant dentistry and navigation surgery. MATERIAL AND METHODS: Six senior dental students were randomly divided into 3 groups for initial training (FH-CI group: pretraining on freehand conventional implant surgery; FH-ZI group: pretraining on freehand ZI surgery; DN-CI group: pretraining on conventional implant surgery under dynamic navigation)...

We present a case of craniofacial dermoid cyst in a 50-year-old female. The patient's complaint was persistent refractory headaches with no other significant neurological symptoms. Diagnostic imaging revealed the presence of a lesion in the left fronto-zygomatic region. Surgical intervention involved a craniotomy that led to a successful excision of the dermoid cyst. The diagnosis was subsequently confirmed by histopathological analysis. This case underscored the importance of considering DC as a potential diagnosis for any craniofacial lesion, given their diverse presentations and associated complications...

Attitudes towards healthcare in the NHS and in other Western healthcare systems have been changing dramatically in recent years. There is a significant movement calling for a shift from the traditional paternalistic model, with patients as passive recipients of treatments that are supported by objective and observable evidence, towards a more holistic approach, in which patients have agency, and treatments are tailored to the individual needs of a particular patient. Whilst patient safety and clinical effectiveness remain intrinsic to the traditional measurement of successful healthcare, Patient Reported Outcome Measures (PROMs) are increasingly being advocated as an important tool to uphold patient-centric care in the NHS...

Reconstruction of maxillary defects can be carried out by a variety of treatment modalities. The choice of modality depends on numerous factors including the size and extent of the defect, patient factors and existing comorbidities. One of the various options is reconstruction and rehabilitation using a fixed prosthesis supported over zygomatic implant. In maxillectomy cases, zygomatic implant can be used to improve the retention of the obturator prosthesis as loss of alveolar bone makes it impossible to use conventional endosseous implants...

AIM: Evaluate the frequency of occurrence of extreme inferior positioning of the Infraorbital foramen from the infra-orbital rim that can potentially interfere with the placement of Quad or Unilateral Double Zygomatic implants. MATERIALS AND METHODS: CBCT scans of 60 patients were read to identify the Infraorbital foramen (IOF)and Infra-orbital rim (IOR). The distances between the two were measured. In cases with increased values, virtual surgical planning was done to evaluate whether two Zygoma implants could be placed in one zygomatic bone...

Pigmented villonodular synovitis (PVNS) is a rare locally aggressive benign tumor in the temporomandibular joint (TMJ). This paper presents a patient with TMJ-PVNS involving masseteric space, temporal bone, zygomatic process, and mandibular ramus. Digital technique was used to determine the boundary of the lesion and reconstruct the normal glenoid fossa. The temporalis myofascial flap was transplanted between titanium mesh and condyle to reconstruct the disk after the complete resection of the tumor. The patient's facial profile is symmetrical, with a mouth ope-ning of 43 mm...

To determine the skeletal changes after midface surgery in patients with syndromic craniosynostosis who underwent Le Fort III (LFIII), monobloc (MB), or facial bipartition (FB). This was a retrospective study including 75 patients: 33 treated by LFIII, 29 by MB, and 13 by FB. Twenty-five had a diagnosis of Apert, 39 Crouzon, and 11 craniofrontonasal syndrome. A three-dimensional mesh was created from the preoperative scan and registered to the postoperative scan to visualise the advancement. LFIII at age 7-12 years effectuated a higher mean advancement in the maxillary (15...

The temporal fascia is a double lamina sandwiching a thick fat layer above the zygomatic bony arch. To characterize each lamina, their developmental processes were examined in fetuses. We observed histological sections from 22 half-heads of 10 mid-term fetuses at 14-18 weeks (crown-rump length, 95-150 mm) and 12 near-term fetuses at 26-40 weeks (crown-rump length, 215-334 mm). The superficial lamina of the temporal fascia was not evident at mid-term. Instead, a loose subcutaneous tissue was attached to the thin, deep lamina of the temporal fascia covering the temporalis muscle...
