ostectomy

BACKGROUND: The early identification of delayed bone healing or a non-union is vital for prompt treatment and superior patient outcomes. Current techniques rely heavily on operator skill for interpretation and hence their reliability and repeatability may be inconsistent. This study assessed the application of computed tomography (CT) derived densiometric measurements as a quantitative tool for the assessment of bone healing. METHODS: This prospective, longitudinal, method comparison study was performed using a recognised sheep tibial ostectomy model...

There are various types of chin deformities, and the least established surgical method for deformity correction may be reduction for anteroposterior macrogenia. Anteroposterior macrogenia is commonly corrected by either setback genioplasty or burring reduction, but these approaches are less likely to produce aesthetically pleasing results. Both procedures have poor reduction effects because of the low response rate of soft tissues to skeletal alterations. There is a high likelihood of chin ptosis and flattening...

This case report describes a 67-year-old woman who developed an extensive, slow-growing lesion occupying the whole of the palate in 10 years. Considering clinical and radiographic features, calcifying neoplasms were considered. Correlating microscopic features with clinical features, the lesion was diagnosed as peripheral ossifying fibroma, which seldom presents as an extensive lesion on the palate amongst the elderly age group. This case report will highlight clinicians and pathologists about a rare presentation of a commonly encountered lesion with a comprehensive view of the differential diagnosis of other comparable lesions...

Mesiodens, which emerge towards the nasal cavity, often require consultation in maxillofacial practice. Typically accessed through wide palatal flaps with ostectomy, this method involves limited visibility and poses the risk of damaging the roots and apex of adjacent dental structures. This study advocates a minimally invasive technique that involves vestibulotomy between the central incisors, facilitating direct and rapid access through nasal floor dissection, minimizing comorbidities. A systematic review was performed, following the PRISMA guidelines, apropos on ten clinical cases reported in this study...

Study Design: Technical note. Objective: The lower nasal architecture is dependent on caudal septal integrity. Deviations of the caudal septum can compromise nasal airflow. The presence of anterior nasal spine deviations contributes to septal and medial crural shifting with ipsilateral encroachment. It is essential to identify nasal spine deviation during surgery in order to reconstruct the septum in a midline position at its base. This allows an appropriate management plan that creates a better functional and aesthetically pleasing outcome...

Bimaxillary surgery is a painful invasive procedure in plastic surgery. Pain control is typically achieved using intravenous analgesics. We aimed to investigate the efficacy of a novel temperature-responsive hydrogel, PF72, mixed with ropivacaine, as a local pain management solution when applied directly to the surgical site following orthognathic surgery. The study was conducted from October 2022 to July 2023 and included a cohort of 40 candidates for orthognathic surgery, encompassing LeFort I maxillary ostectomy and sagittal split ramus osteotomy...

INTRODUCTION: Cone beam computed tomography (CBCT) is reliable in the assessment of structures related to teeth. The assessment of the inferior alveolar neurovascular (IAN) bundle location using CBCT is considered one of its prime uses in different mandibular surgeries. METHODOLOGY: Retrospective CBCT data of patients presented to the institute were assessed to measure relations of IAN. Measurements were taken to assess the bone thickness adjacent to IAN, the superior-inferior dimension between the canal and the teeth, and the dimension between the canal and the inferior border of the mandible...

Virtual surgical planning enables precise surgical planning and translation of this planning into the operating room. Preoperative maxillofacial computed tomography scans are compared to a reference skull to identify desired surgical changes. In facial feminization surgery, these include forehead recontouring/frontal table setback, gonial angle reduction, and possible chin repositioning/reshaping, while in facial masculinization surgery, this includes forehead augmentation and gonial angle/chin augmentation...

OBJECTIVE: This article presents technical guidelines for perio-restorative esthetic crown lengthening, along with a discussion of the biologic rationale. A classification system is proposed to assist in treatment planning and sequencing the surgical and restorative phases. CLINICAL CONSIDERATIONS: When esthetic crown lengthening is performed as an adjunct to restorative therapy, the surgical approach must be determined by the anticipated position of the restorative margins...

BACKGROUND: Wound dehiscence is a known postoperative complication, but in cervical spine surgery it is rare and there is a lack of documented literature. This case report discusses novel complications of wound dehiscence in three patients who were treated with spinous process ostectomies after posterior cervical surgeries. CASE DESCRIPTION: In total three cases are reported in these reports. Case one documents the management of a patient with full-thickness cervical wound dehiscence following a cervical paraspinal infection corrected with posterior spinal fixation and fusion...

Variants of the cranial closing wedge ostectomy (CCWO) may be used to manage cranial cruciate ligament deficient stifles by reduction of the tibial plateau angle (TPA). Concerns have been raised about predictability of achieving target TPA, limb shortening, axis shift, and distalization of the tibial tuberosity. Landmarks derived from tibial radiographs (n = 50) by 5 observers, along with outlines of the cranial and caudal proximal tibial cortices, were used to simulate six CCWO variants. Tested variants were Slocum-type (n = 2), modified (n = 2), isosceles, and anatomical-mechanical axis (AMA)-based CCWO...

A 9-month-old mixed-breed dog was presented for bilateral proximal tibial deformity resulting in an excessive tibial plateau angle and cranial cruciate ligament insufficiency. Initial surgical management of the right pelvic limb was done by performing a cranial closing wedge ostectomy. Inadequate leveling of the plateau resulted in a postliminal meniscal tear which was addressed during a revision tibial plateau leveling osteotomy. The left pelvic limb was managed in a single-session surgery using three-dimensional (3D) virtual surgical planning and custom 3D-printed surgical guides to perform a combined cranial closing wedge ostectomy and tibial plateau leveling osteotomy...

OBJECTIVE: To determine the effects of using either a linear or curvilinear oscillating, battery-powered saw blade on the extent of bone resection, bone fissure or fragmentation, soft tissue trauma, and surgical time for femoral head and neck excision (FHNE) in feline cadavers. ANIMALS: 18 feline cadavers. METHODS: Paired feline cadaveric femora were randomly assigned to either a 10 mm linear or 12 mm curvilinear blade for FHNE by 2 surgical residents...

Immediate and longer-term outcomes of a cranial closing wedge ostectomy variant for management of canine cranial cruciate ligament disease were assessed in this single-center retrospective consecutive study. Records and radiographs were retrieved and assessed by three independent observers to evaluate tibial plateau angle, anatomical-mechanical axis angle, tibial tuberosity distalization, and mechanical axis length before and after surgery. Kinetic gait analysis and owner questionnaires were used to assess clinical outcomes...

PURPOSE: Cortical porosis, secondary to either vascular injury or stress-shielding, is a comorbidity of fracture fixation using compression bone plating. Locking plate constructs have unique mechanics of load transmission and lack of reliance on contact pressures for fixation stability, so secondary cortical porosis adjacent to the plate has not been widely investigated. Therefore, this study aimed to assess the effects of long-term locking plate fixation on cortical dimensions and density in a caprine tibial segmental ostectomy model...

Our objective was to report the use of distraction osteogenesis at the site of angular limb deformity correction using external skeletal fixation for treatment of 1 femoral and 1 tibial angular limb deformity in 2 large-breed puppies. Medical records were reviewed from 2 dogs (a 7-month-old intact male golden retriever and a 4-month-old intact female German shepherd mixed breed) diagnosed with angular limb deformities and truncation of a pelvic limb. Surgical treatment consisted of neutral wedge ostectomy and distraction osteogenesis at the site of bone deformity with an external skeletal fixator (ESF)...

BACKGROUND: Patients with dysplastic bone diseases, including fibrous dysplasia (FD), represent a particular challenge for placement of dental implants. This is due to structural bony changes that may compromise the bone blood supply and plasticity, thus potentially affecting the process of osseointegration. This case report describes a novel approach for dental-implant-based rehabilitation of the posterior maxilla affected by craniofacial fibrous dysplasia (CFD), with 7 years of treatment follow-up...

BACKGROUND: Numerous surgical options for correcting prominent mandibular angles in East Asians have been reported. The objective of this study is to investigate the importance of remodeling physiological mandibular angle by comparing the surgical effects and complications of mandibular "V-line" ostectomy and long curved ostectomy. METHODS: A retrospective study was conducted on patients who underwent either mandibular "V-line" ostectomy (Group I) or long curved ostectomy (Group II)...

As the most prominent feature of the lower face, the chin is crucial to human facial morphology and it plays a large role in contributing to facial attractiveness and harmony. Although an increasing number of genioplasty procedures are being introduced for chin augmentation, chin reduction procedures are rarely performed. Due to the inevitable cervicomental angle (CA) widening and relaxation of the floor-of-mouth muscles caused by chin shortening and the elevation of the lower edge of the mandible, chin reduction remains a challenging procedure...

OBJECTIVES: This study explored the efficacy of collecting temporal fracture site compliance data via an advanced direct electromagnetic coupling (DEC) system equipped with a Vivaldi-type antenna, novel calibration technique, and multi-antenna setup (termed maDEC) as an approach to monitor acute fracture healing progress in a translational large animal model. The overarching goal of this approach was to provide insights into the acute healing dynamics, offering a promising avenue for optimizing fracture management strategies...
