상악골 Maxilla

Orthognathic surgery has long been successfully utilized to correct dentofacial deformities to help facilitate improved oral function and facial esthetics. The treatment, however, has been associated with a high degree of complexity and sev…

Reconstruction of defects of the jaws is mainly performed via free fibula flap. An incidence of 2-21% of overall flap failure is still described. We investigated the roles of volume, length and number of fibula flap segments on flap surviva…

The reconstruction of mandibular defects may be delayed or compromised for many reasons, especially in pediatric patients. With the growth of the remaining mandible and the maxilla in the malocclusion status, secondary dentomaxillofacial de…

[OBJECTIVES] To describe the experience of two tertiary academic centers with multiple, simultaneous free flaps for complex head and neck defect reconstruction. [METHODS] Patients undergoing multiple, simultaneous free flaps from 2017 to 2…

[BACKGROUND/AIM] A feline inductive odontogenic tumor (FIOT) is a rare type of tumor that is unique to young cats. [CASE REPORT] Herein, we report on three cats (aged 6 months to 2.5 years) that had a bulging mass on the maxilla. On diagno…

Head and neck free flap survival relies on adequate tissue perfusion from the external carotid artery (ECA), and vessel length is inversely proportional to blood flow rate. Investigate whether distance from the ECA (as a proxy for pedicle …

Total rhinectomy is ontologically necessary for large and locally invasive carcinomas of the nasal cavity owing to the complex three-dimensional structure of the nose. Reconstruction options include singular or combined options of local tis…

Ossification of vascular pedicle in free fibular flap for jaw reconstruction was a rare complication. The aim of our study is to evaluate its consequence and propose our clinical experience with surgical management and outcomes of this comp…

[PURPOSE] Postoperative pulmonary complications (PPCs) are one of the most significant complications following head and neck cancer surgery (HNCS). Patients requiring tracheostomy, free tissue transfer reconstruction, and postoperative vent…

[PURPOSE] Orthognathic surgery (OGS) using the surgery-first approach (SFA) can decrease treatment time and increase patient satisfaction. Clockwise rotation (CWR) of the maxillomandibular complex to correct mandibular prognathism leads to …

Maxillary growth inhibition in patients with cleft lip and palate (CLP) is an undesired effect that may occur in the teens despite proper primary care. Dental malocclusion and distortion of facial appearance can be treated with external dis…

Recently, the number of survivors that had oral cancer has increased, but deterioration in the quality of life of patients concerning oral function and cosmetic appearance has become problematic. Prosthodontic dentures usefully treat jaw de…

This is a monocentric, retrospective study of patients who underwent successful immediate or delayed maxilla or mandible reconstructions with FFF from January 2005 to December 2021. Panoramic radiograph, computed tomography scans, and cone-…

Ablative defects of the maxilla caused by malignant tumours create a multitude of difficulties for patients and the clinical teams looking after them. Tumours of the maxilla, while relatively uncommon, require significant multi-disciplinary…

Background: When maxillary transversal expansion is needed, two protocols of treatment can be used: a maxillary orthodontic expansion followed by a classical bimaxillary osteotomy or a bimaxillary osteotomy with maxillary segmentation. The …

Maxillectomies cause malocclusion, masticatory disorders, swallowing disorders and poor nasolabial projection, with consequent esthetic and functional sequelae. Reconstruction can be achieved with conventional approaches, such as closure of…

Traditionally patients can remain nil by mouth (NBM) for up to 12 days after oral tumour resection with free flap reconstruction to reduce the risk of flap dehiscence, poor healing and fistulae. The literature reports that patients could on…

[BACKGROUND] Surgical ciliated cysts, also known as postoperative maxillary cysts or implantation cysts, occur mainly in the posterior maxilla after radical maxillary sinus surgery; they rarely develop in the mandible. They are thought to o…

[BACKGROUND] There is a rare need for postoperative non-invasive positive pressure ventilation (NIPPV) following microvascular reconstruction of the head and neck. In midface reconstruction, the free flap vascular pedicle is especially vuln…

Smiles with excessive gingival display exceeding 3 mm are considered unattractive. Excessive muscular contraction of lip elevator muscles is the etiology in most cases, and other factors, such as excessive vertical dimension of the maxilla …
