Neuroendocrine and undifferentiated sinonasal and skull base tumors: An up-to-date narrative review
In conclusion, neuroendocrine and undifferentiated tumors arising from the nose, paranasal sinuses and the skull base represent a unique group of malignancies. A thorough understanding of their clinical features, molecular changes, diagnostic approaches, treatment modalities, and prognostic factors is critical for providing optimal patient care. Still, continued research efforts and multidisciplinary collaboration are warranted, in order to improve outcomes for patients diagnosed with these rare and aggressive tumors.

Scapula harvest in the supine position for immediate mandibular reconstruction
ConclusionHarvesting of the scapula in the supine position is a feasible option for immediate mandibular reconstruction. Although deep anatomic knowledge and technical expertise are necessary, this strategy can eliminate positional change and significantly reduce the operative time.

Influence of the maxillary third molars and the surrounding cortical plate during maxillary tooth movement with TADS- A CBCT Study
ConclusionThe integrity of the cortical plate and the relative position of the maxillary third molar to the second molar influence the amount of distal movement of the maxillary first permanent molar during distal movement of the maxillary teeth with TADS.Clinical relevanceThe amount of distal movement of the maxillary dentition appears to depend on the presence or absence of the third molars and the condition of the cortical plate in the region of the maxillary tuberosity and thereby greatly influence the outcome of treatment.

Pyodermatitis-pyostomatitis vegetans: a case report and systematic review focusing on oral involvement
ConclusionsSixty-two publications with 77 cases of PSV and an associated IBD were included. Features that are helpful in establishing the diagnosis of PSV are snail track appearance of oral lesions, an associated IBD (which is not always symptomatic), evidence of intraepithelial clefting on microscopic examination of oral lesions, and peripheral blood eosinophilia. A gold standard for the management of PSV does not exist and high-level evidence is limited. There is no established therapeutic protocol for PSV and management primarily consists of topical and/or systemic corticosteroids, antirheumatic drugs (sulfasalazine, me...

Speech following Le Fort I Maxillary Advancement in Cleft Maxillary hypoplasia – an objective and subjective outcome analysis
ConclusionThe primary cause for functional impairment and poor aesthetics in cleft deformity is the maxillary hypoplasia and therefore, should be the focus during correction. The pre-operative VP status or the amount of maxillary advancement could not predict the postoperative VP status. Maxillary advancement over 10 mm did not seem to significantly affect the final VP status. Articulation improves due to increased tongue space and favorable dental segment positioning. Mild to moderate immediate post op changes in nasality improves or even reverts to their preoperative status in the majority of the cases in ab out six mo...

Influence on marginal bone levels at implants equipped with blades aiming to control the lateral pressure on the cortical bone. An experimental study in dogs
ConclusionsThe lowest bone crest resorption and highest levels of osseointegration were observed in the 0.0 μm and + 50 μm groups. The cortical region where the blades had performed their cutting action showed regular healing with perfect hard and soft tissues sealing in all the groups. Cortical blades gathered bone particles, particularly in the + 200 μm group, which were incorporated into the newly formed bone. The results from the present experiment provide support to the use of blades that produce a marginal gap of 50 μm after implant insertion. (Source: Oral and Maxillofacial Surgery)

Influence of keratinized mucosa on peri-implant diseases: a retrospective cohort study in humans
ConclusionIn conclusion, in the present sample, keratinized buccal mucosa width was not associated with peri-implant diseases, suggesting that a band of keratinized mucosa may not be necessary to maintain peri-implant health. Prospective studies are required to better understand its role in the maintenance of peri-implant health. (Source: Oral and Maxillofacial Surgery)

Risk factor analysis for perioperative complications in impacted third molar surgery – a single center experience
ConclusionNext to the risk factors from above, the present study is one of the first showing that patients who were primarily operated on by an oral surgeon (DMD) and not a maxillofacial surgeon (MD, DMD) showed higher rates of OAC and IAN hypesthesia in impacted third molar extraction. The results of this study can serve as a baseline for further studies to investigate complication patterns in impacted third molar surgery. (Source: Oral and Maxillofacial Surgery)

Surgical and conservative treatment outcomes of medication-related osteonecrosis of the jaw located at tori: a retrospective study
ConclusionProphylactic and therapeutic surgical removal of tori are reliable treatments and should be considered if a patient ’s general health allows surgery.Trial registrationThe study was approved by the Regional Scientific Ethical Committee (H-6 –2013-010) on November 20, 2013, and was retrospectively registered.

Squamous cell carcinoma of mandibular gingiva producing both parathyroid hormone-related protein and granulocyte colony-stimulating factor: a case report
We describe a case of mandibular gingival carcinoma with hypercalcaemia and leukocytosis caused by tumour-derived parathyroid hormone-related protein (PTHrP) and granulocyte colony-stimulating factor (G-CSF). A 54-year-old man presented to our Department of Oral and Maxillofacial Surgery with a chief complaint of a left-sided mandibular gingival ulcer. A 42 mm × 20 mm sized ulcer was found on the left lower molar gingiva. Squamous cell carcinoma was pathologically diagnosed. The patient underwent a hemimandibulectomy, left-sided radical neck dissection, plate reconstruction, pectoralis major musculocutaneous flap recon...
