Objective: The aim of this study was to evaluate a multimodality approach to sentinel lymph node biopsy (SLNB) detection with lymphoscintigraphy and single-photon emission computed tomography (SPECT)/computed tomography (CT). When combined with intraoperative imaging by a portable gamma camera (PGC), improved SLNB accuracy and detection rate may r...

The standard of mandibular reconstruction has increased since the introduction of computer-assisted design (CAD) and rapid prototype modelling (RPM) for surgical planning. Between 2008 and 2013, a prospective pilot study of 20 patients was planned to compare the outcomes of patients treated by mandibular reconstruction who had CAD and RPM-guided op...

Purpose Many types of soft tissue grafts have been used for grafting or prelaminating bone flaps for intraoral lining reconstruction. The best results are achieved when prelaminating free flaps with mucosal grafts. The authors suggest a new approach to obtain keratinised mucosa over a fibula flap using full-thickness engineered autologous oral muco...

Microvascular surgery has become the preferred method for mandibular reconstruction. A neck incision frequently is required for malignant tumor resections to carry out the dissection. The authors suggest a rhytidectomy approach for mandibular reconstruction with microvascular free flaps after the resection of benign tumors. Seven patients with late...

The alveolar cleft is a bony defect that is present in 75% of the patients with cleft lip and palate. Although secondary alveolar cleft repair is commonly accepted for these patients, nowadays, controversy still remains regarding the surgical technique, the timing of the surgery, the donor site, and whether the use of allogenic materials improve th...

FAT1, which encodes a protocadherin, is one of the most frequently mutated genes in human cancers1–5. However, the role and the molecular mechanisms by which FAT1 mutations control tumour initiation and progression are poorly understood. Here, using mouse models of skin squamous cell carcinoma and lung tumours, we found that deletion of Fat1 accele...

Nasal amputation and nasomaxillary defects, need to reconstruct the internal lining, osteochondral structure, and external coating of the nose. Authors report a 70-year-old male and a 65-year-old female treated for nasomaxillary defects (Brown JS, Shaw RJ. The Lancet Oncology 2010;11:1001-1008) due to squamous cell carcinoma (SCC) where the tip of...
Article
In November 2014 the Spanish Society of Otolaryngology, the Spanish Sleep Society and the Spanish Society of Maxillofacial Surgery proposed and endorsed the development of a Clinical Practice Guideline on the physical examination of the upper airway in patients with obstructive sleep apnoea. The Guideline strictly followed the recommendations of th...

Background Oral premalignant lesions (OPML) are frequently extensive and multifocal leading high morbidity for patients. Although oral squamous carcinoma (OSCC) in non‐smoker patients is increasing, little is known about OPML and the carcinogenesis process in these patients. The aims of the study were to insight and compare the clinicopathological...

Background: Midface advancement is a keystone intervention in the treatment plan of syndromic hypoplasia of the midface. Although earlier authors had been using a combination of smaller incisions to acquire enough access to perform the different osteotomies, Tessier popularized the bicoronal incision. This approach can be time-consuming however an...
Conference Paper
Oral rehabilitation is the final objective of treatment in patients treated for maxillofacial microvascular reconstruction. Covering the defect is the primary objective, but function and aesthetics are completely achieved after dental rehabilitation. Peri-implant health is difficult to achieve and mantain due to the bulky soft tissue component of t...

La biopsia del ganglio centinela en el carcinoma escamoso de la cavidad oral es un tema controvertido aunque varios estudios hayan demostrado su viabilidad, probablemente por la elevada tasa de falsos negativos en los tumores del suelo de la boca. Presentamos el caso de un hombre de 54 años con carcinoma escamoso del suelo de la boca T1N0 que se so...
Article
The main objectives in mandibular reconstruction search to recover shape, function and aesthetics. To achieve these objectives free flaps are performed. Currently fibula and iliac crest free flap are the main options for mandibular reconstruction. Preoperative planning and rapid prototyping, let us achieve better results, obtaining a better tridime...
Article
Autologous fat grafts have gained popularity among Cranio-Maxillofacial surgeons within the past years, since clinical works by Coleman and others, have shown that it is possible by careful handling of the transplanted fat to improve the long term results . The main indication for structural fat grafting, lipostructure technique or Coleman techniqu...

The expression of cellular prion protein in the central nervous system of normal cats and in cases of kainic acid injections into the mediodorsal thalamic nucleus were studied. Cellular prion protein immunodetection varied in a rostrocaudal direction: the protein was less abundant in the brainstem than in the prosencephalon. Especially abundant wer...

We present a rare complication that appeared after an attempt to extract the included third molar with local anaesthesia at the odontologist office. The patient was admitted to the emergency room to have the tooth removed cervically under general anaesthesia and nasotracheal tubation because of its movement towards the submandibular fossa during th...

The first publication on Lemierre Syndrome appears in 1936 by Lemierre. It is defined as an "oropharynx bacterial infection characterized by the thrombophlebitis in the internal jugular vein, derived in a systemic septic embolism". In 81% of the cases, the Fusobacterium necrophorum is the most frequent etiologic agent. Fever is the most common symp...
