The buccinator flap is currently one of the best techniques for the reconstruction of defects in the oral cavity and other sites. Reconstruction of the palate is a major challenge because of the functional consequences of the excision of lesions in this area. The main goal is to maintain separation between the mouth and the nose. We have done a cross-sectional retrospective descriptive study of a series of cases reconstruction of palatal defects with buccinator flap at the University Hospital Miguel Servet in Zaragoza during a six-year period and compared our results, morbidity, and mortality with those of published series. The main complication was partial loss of the flap. We have analysed the reasons for this and report the steps needed to avoid it., (Copyright © 2016 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Prognostic stratification in squamous cell carcinoma (SCC) of the head and neck has traditionally relied on the pathological staging of a tumour, but it is increasingly being recognised that host-related factors have an important role in the assessment of survival and recurrence. We aimed to evaluate the prognostic value of systemic inflammation scores including the modified Glasgow Prognostic Score (mGPS) in patients undergoing potentially curative resection for oral SCC. We retrospectively identified 178 patients who had curative operations for cancer of the oral cavity and soft palate between January 2006 and April 2011. Among the inclusion criteria were preoperative estimates of C-reactive protein and serum albumin. We analysed established pathological prognostic factors and scores for systemic inflammation as predictors of cancer-specific and overall survival. On univariate analysis, the mGPS was a significant predictor of both cancer-specific (p<0.001) and overall survival (p<0.001), and it remained an independent predictor of cancer-specific (HR: 2.12, 95% CI 1.49 to 3.00; p<0.001) and overall survival (HR: 1.69, 95% CI 1.23 to 2.31; p=0.001) on Cox regression analysis. The mGPS of activated systemic inflammation seems to be a powerful adverse prognostic indicator in resectable oral SCC., (Copyright © 2014 The British Association of Oral and Maxillofacial Surgeons.

The purpose of this study was to define the incidence of cervical metastasis in squamous cell carcinoma (SCC) of the maxillary alveolus, hard palate and gingiva; to identify patterns of locoregional failure and to assess survival outcomes. We retrospectively analysed 30 patients treated for SCC of the maxillary alveolus and hard palate between 2000 and 2010. Parameters assessed included the incidence of cervical metastasis at presentation and recurrence, paying particular attention to tumour staging and survival outcomes. Of our 30 patients, 25 were confirmed to have T4 SCC of the maxillary alveolus and hard palate with bone invasion. Cervical metastases had been noted in 7 (23%) patients at initial presentation. A total of 9 (36%) patients developed regional failure in the pT4 SCC group shortly after primary resection. Patients with advanced primary SCC of the hard palate and maxillary alveolus (particularly when there was bone invasion) showed high rates of regional failure, and in most cases successful salvage was not achieved. Based on our findings and a review of the existing literature we strongly recommend elective neck dissection for patients with pT4 SCC of the maxillary alveolus and hard palate., (Copyright © 2013 The British Association of Oral and Maxillofacial Surgeons.

The coexistence of different types of malignancy in cervical lymph nodes has been reported previously. We report the first case, to the best of our knowledge, of concurrent metastatic adenoid cystic carcinoma and squamous cell carcinoma (SCC) in cervical lymph nodes. A primary SCC developed three decades after treatment for adenoid cystic carcinoma of the palate, and the synchronous metastases became clinically apparent the following year. The aetiology of the SCC may have been related to radiotherapy or smoking. Whether the adenoid cystic carcinoma would have remained dormant, or was reactivated after perturbation of host defence mechanisms, is not known., (Copyright © 2012 The British Association of Oral and Maxillofacial Surgeons.

This study evaluated the applicability of pedicled buccal fat pad grafting for the reconstruction of defects surgically created during oral surgery. A buccal fat pad graft was applied in 23 patients (5 males, 18 females; mean age 68.3 years) between 2003 and 2011. The graft was used to cover surgical defects of the palate, maxilla, upper gingiva, buccal mucosa, lower gingiva, oral floor, and temporomandibular joint region. Size of the surgical defects ranged from 15mm×12mm to 30mm×40mm; size of the buccal fat pad ranged from 15mm×12mm to 43mm×38mm. A pedicled buccal fat pad was prepared by incising the maxillary vestibule following primary surgery, and the surrounding connective tissue was preserved to supply nutrition to the pedicle during surgery. The buccal fat pad was placed on the raw surface of soft tissue or bone surface and sutured to the surrounding tissue of the defect. Complete epithelialization was observed within 4 weeks postoperatively. There were no complications or functional disorders during follow-up. Buccal fat pad grafting appears to be feasible for the reconstruction of surgically induced defects, and can be extended to the palate, mandible, mouth angle, and temporomandibular joint region., (Copyright © 2012 International Association of Oral and Maxillofacial Surgeons.

Adenoid cystic carcinoma is a tumour of glandular cells responsible for 10% of salivary gland neoplasms. It has a high rate of perineural spread but limited involvement of regional lymphatics even in late stage disease. Early survival is typically good (60-90%) although long term survival is poor with spread to distant sites in 40-60% of cases. The authors performed a retrospective review of clinical and pathological records for 24 patients managed by their institution over a 22-year period. The overall 5, 10 and 20-year survival rates in this study were 92%, 72% and 54%, respectively. Perineural invasion was seen in 63% and close or positive margins seen in 64% of all primary resection specimens although survival was not associated with any clinical factor other than the initial size of lesion. Most patients presented complaining of a lump, whilst a burning neuralgia-type pain was the second most common symptom. The study confirms the conclusion of previous studies that tumour size at diagnosis is the most important predictor of outcome., (Copyright © 2011 International Association of Oral and Maxillofacial Surgeons.

Teratomas of the head and neck are uncommon congenital lesions, which are rarely seen in the soft palate. We here reported a male neonate with a soft palate teratoma associated with soft palate cleft. The most common presenting symptom of oral teratoma is feeding problems. The tumour looks like a mushroom, and was successfully treated with surgery. Feeding returned to normal by removing the mass, and the patient is under follow up for selective operation of the cleft palate. This case is unique because teratoma in a mushroom shape was not reported before., (Copyright 2010 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

We retrospectively studied 17 patients with squamous cell carcinoma (SCC) of the maxillary gingiva, alveolus, and hard palate who were treated over a 7-year period (2000-2007) to investigate whether selective neck dissection is justified at an early stage. Four patients presented with metastases in the neck, and all developed early recurrence in the neck, with poor prognosis. Of the 13 patients who initially had no sign of metastases, two developed regional metastases within the first 18 months of initial treatment. Squamous cancers of the maxillary gingiva, alveolus, and hard palate should be treated aggressively, and elective neck dissection should be considered because of the high risk of occult metastases. Prospective studies are difficult because of the rarity of the tumour., (Copyright 2009 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.)

Congenital teratoma is a rare malformation, and few papers have been published about it. We present a large teratoma that arose from the hard palate in a neonate. The obstructive mass caused maternal polyhydramnios and was identified prenatally by ultrasonography. The mother went into labour at 35 week's gestation at home. The child was in respiratory distress as a result of airway obstruction, and a tracheostomy was done when she was 4hours old. She also had major cardiac abnormalities. The palatal mass was removed successfully at 4 weeks of age. The typical components of a teratoma were identified including immature neural glial tissue.

Here is described a modified technique of palatomaxillary reconstruction that combines the use of a free vascularized bone graft by osteotomy, soft-tissue flap, zygomatic implant as an anchorage and two standard implants simultaneously. The patient presented with deformity in the left face after subtotal maxillectomy (Brown 2b classification). Preoperative work up was performed by a rapid prototyping model using computer-aided manufacturing technology. The purpose of this model is to provide accurate measurements of the defect. The palatomaxillary three-dimensional buttress system can be managed by orienting the bone graft vertically and horizontally. Reconstruction of the palatomaxillary defect was successfully accomplished in a single surgical procedure. Dental implant restoration achieved good osseointegration without any significant resorption. This new modification represents a significant contribution to palatomaxillary reconstruction using zygomatic implants as anchorage.

The authors describe their experience with the submental island flap for the primary correction of head and neck deformities following oncologic surgery, over the past 5 years. The use of this flap is reported in 12 patients, with a mean age of 67 years, requiring facial or intraoral reconstruction. A brief review of the key points and some refinements in the operative technique are discussed. The reconstruction of defects with a submental island flap was successful in every patient. Complications encountered were one case of temporary palsy of the marginal mandibular branch of the facial nerve and one case of orocutaneous fistula. All the donor site defects were closed primarily. The submental island flap is an excellent choice for the reconstruction of head and neck defects because of its reliability, versatility, colour and texture match, and relative ease of application.

In this article a new method of closing palatal defects by means of buccal fat pad flaps is reported. A double buccal fat pad flap in association with Le Fort I osteotomy approach was adopted to remove tumours of the palate and nasal fossae. The technique is described in a case of adenocarcinoma arising from the nasal septum and its indications and advantages are discussed.

In the surgical management of oral cancer the resection and reconstruction of the mobile tongue and soft palate are most important if function is to be maintained. The present trend towards primary laryngeal surgery for early disease has emphasized the importance of primary surgery if good functional outcomes can be achieved. This study compares the functional and health-related quality of life outcomes for primary surgery and reconstruction of the anterior tongue and soft palate. From a cohort of 566 patients treated from 1992 to 2002, 118 fitted the criteria for anterior tongue and 44 for soft palate resection. University of Washington Quality of Life scores were available in around three quarters of patients. In terms of speech and swallowing a 3/4 or total anterior glossectomy had a worse outcome than a 1/4 or 1/2. In patients having a 3/4 or total resection of the soft palate however, the results showed a similar outcome to those with 1/4 or 1/2 resection. The functional results of 3/4 and total soft palate reconstruction were superior to 3/4 and total anterior tongue resections and were similar to the whole cohort. This finding extends the role of functional surgery in the oropharynx for which primary radiotherapy is often preferred to preserve function.

Oral malignant melanoma is extremely rare and carries a poor prognosis. The treatment of choice remains controversial. We retrospectively studied 35 patients with primary malignant melanoma of the oral cavity between 1970 and 2001 to define the clinical features of this disease and evaluate treatment methods. The main variables studied were clinical findings, response to therapy, and outcome. Surgery with complete macroscopic resection was performed at the primary site in 13 patients (surgery group) and radiotherapy was done without surgery in 17 (non-surgery group). The 5-year cumulative survival rate was 15.4% in the surgery group, 35.3% in the non-surgery group, and 21.8% overall. Distant metastasis was present in 64.7% (11/17) of the non-surgery group and 76.9% (10/13) of the surgery group. Improved outcome in oral malignant melanoma requires the development of new therapies and the prevention of distant metastasis.

Polymorphous low-grade adenocarcinoma (PLGA) is an uncommon tumour that usually affects the minor salivary glands, particularly in the palate. It is rare in young patients, and here we report a case in a teenage girl. She presented at the age of 16, although the lesion had been noticed 2 years previously. The tumour showed histopathological features of PLGA, but recurred locally, behaved aggressively, and ultimately metastasised to cervical lymph nodes. This was accompanied by an altered histological picture, with a papillary cystic pattern and necrosis becoming progressively more prominent. PLGA is not always a low-grade lesion and some tumours, notably those with a papillary cystic growth pattern, may require more aggressive treatment.

Hairy polyps (dermoids or oronasopharyngeal teratomas) are a type of congenital tumour that contain elements of bigerminal origin (ectoderm and mesoderm). We describe a baby who presented with a hairy polyp of the hard palate protruding from the mouth. This was not causing respiratory distress but she had feeding difficulties. She was successfully operated on the age of 5 days, the defect was reconstructed with hairless skin of the mass and she was able to suck after a month.

From March 1991 to February 2001, 80 cases of minor salivary gland tumours were diagnosed in the Department of Oral and Maxillofacial Surgery at the University of Maryland at Baltimore (Baltimore, MD, USA). Data extracted from a retrospective chart review included age, sex, symptoms, site, histological diagnosis. treatment and outcome. Pleomorphic adenoma was the most common benign tumour and makes up 89.5% of all benign tumours. The percentage of malignancy (76.3%) was much higher than that found in other studies. Of the malignant tumours, 54.1% were mucoepidermoid carcinomas. This study differs from many previous reviews that were published by pathologists rather than a surgical unit.

The present study was undertaken in order to determine whether surgical treatment of oral leukoplakia reduces the risk of the subsequent development of carcinoma. This study included 142 patients with oral leukoplakia who received or did not receive surgical treatment. All subjects were followed-up for more than 6 months with a mean follow-up period of 4 years. Malignant transformation rate was lower among patients who received surgical excision (1/75) than among those who did not receive surgical treatments (4/51). However, the malignant transformation rates were high in patients who received cryosurgery (3/12) or cryosurgery plus surgical excision (1/4). There was no obvious relation between the grade of epithelial dysplasia and the rate of malignant transformation. Our results suggest that surgical excision of oral leukoplakia may reduce the risk of the subsequent development of carcinoma.

Head and neck surgery may involve complex methods of composite reconstruction that do not replicate the volume and contour of the normal anatomy. 'Functional' reconstruction implies replication of the normal volume and contour of both hard and soft tissues to produce normal form and function of the face, mouth and jaws. Techniques such as stereoscopic lithography and computer-assisted design, and-manufacture (CAD-CAM) have been successfully used with computer-numerized control (CNC) milling to manufacture customized titanium implants for single-stage reconstruction of the maxilla, hemimandible and dentition without the use of composite flap cover after the removal of tumours. Reduction in theatre time and personnel, less need for intensive care, and earlier discharge from hospital, indicate possible savings of Pound Sterling 17,000-Pound Sterling 19,000 per patient. There are implications for surgery in general, and further research and development is advocated.

Malignant mucosal melanoma represents 0.3 to 10% of all melanomas. The majority of these lesions arise in the oral cavity or paranasal sinuses. Very few authors report reliable treatment results, however all suggest a uniformly poor outcome. A retrospective analysis of all cases of upper aero-digestive tract melanoma (UADT) treated since 1982 at our centre are presented. During the 15-year period, nine cases of UADT melanoma were identified. Three patients had a lesion in the palate, two in the maxillary alveolus, two in the oropharynx, while one each had a lesion in paranasal sinus and lower alveolus. Mean age was 43.25 years (28-62 years), with a male to female ratio of 1.6:1. Cervical lymphadenopathy was the commonest presenting symptom in seven patients. Radical surgery was carried out in three patients, wide excision in three and radical neck dissection in six, while no surgical intervention was undertaken in two patients. Median follow-up time was eleven months. In four patients, local recurrence occurred, while three developed pulmonary metastasis. One patient was lost to follow-up. We suggest that data from various centres be pooled together in order to carry out a meta-analysis to address the question of optimal treatment for malignant melanoma of the upper aero-digestive tract.

Three patients with oral malignant melanoma, who survived for at least ten years after initial examination, are presented. The depth of tumor invasion was 5 mm or less in all patients. The first patient received surgery and postoperative immunotherapy and she had no recurrence more than 18 years after treatment. The second patient underwent surgery but had local recurrence after 11 years. He underwent resection and postoperative chemotherapy and was still alive more than 14 years after initial examination. The third patient received radiotherapy and had metastasis nine months after treatment. Resection and radiotherapy were performed and the patient was alive more than 14 years after first presentation.

Ninety-one cases of adenoid cystic carcinoma (ACC) of the salivary glands with more than ten years' follow up were studied to investigate factors influencing the survival rate of patients, which vary according to site, histological type, clinical stage and nature of therapy. The data were statistically analysed for survival curves. Log rank tests were employed to assess the statistical significance of various groups. As a result, it may be concluded that tumour site, clinical stage and histological type are the important factors influencing the prognosis. ACC of the palate and parotid, early clinical stage, glandular/tubular histological type, and tumour without nerve involvement had the best prognosis. ACC in the submandibular gland, maxillary antrum and tongue, advanced clinical stage (stage III and IV), solid histological type, and tumour with nerve involvement had a poor prognosis.

While raising a standard radial forearm free flap, the ulnar artery was inadvertently cut. Therefore, the flap was raised, pedicled on the ulnar artery and vein. The case is discussed in the light of alternative solutions. Sommaire. Durant le prélèvement d'un lambeau radial libre classique, l'artère cubitale a été accidentellement sectionnée. Le lambeau a donc été prélevé, pédiculé sur les vaisseaux cubitaux. Les solutions alternatives possibles devant cette complication et les raisons de notre choix sont discutées.

A new bilayer membrane proved effective as a mucosal substitute. The membrane is composed of an outer layer of silicone and an inner layer of dehydrothermally cross linked composites of fibrillar and denatured collagen sponge. The membrane was placed on oral mucosal defects of five patients after operations for cancer. Ten to 14 days after application the outer silicone sheet was removed, leaving only the inner collagen sponge layer into which cellular tufts of fibroblasts and capillaries had infiltrated. The infiltrated collagen matrix became a new connective tissue that epithelialised rapidly by migration of peripheral epithelium 4-5 weeks after application. In all cases the postoperative course was unremarkable and the repair was effective.

A technique for resection of a palatal tumour via a Le Fort 1 maxillary access osteotomy is described. Access via the osteotomy allows intra-operative examination of the superior aspect of the palate and resection of the tumour without gross destruction of the nasal mucosa. The nasal mucosa provides a bed for a full-thickness skin graft to effect closure of the palatal defect.

The lateral vastus muscle flap has the potential to become one of the most appropriate free flaps for reconstructive surgery in the oral maxillofacial area in selected cases. The flap is relatively easy to harvest and gives rise to little donor site morbidity. The quality of the large diameter vessels allows for relatively easy microsurgical anastomosis. Nerve anastomosis is possible, which makes it extremely suitable for tongue reconstruction.

A method for primary reconstruction of the soft palate following radical tumor resection is described. The resulting defects can be repaired with 2 layers of tissue by combination of a cranial pedicled pharyngeal flap and a cranial pedicled intraoral cheek transposition (IOCT-) flap. For additional resection of the lateral pharyngeal wall the technique can be combined with a masseter crossover flap. The method allows satisfying restoration of swallowing and speech with relatively small operative effort.

Various surgical approaches to the region are discussed, and the procedure according to Hernandez Altemir (1986) described in detail. Six cases are presented to illustrate how this versatile osteoplastic technique may be adapted for individual patients.

Intraoral defects may be reconstructed in many ways following cancer resection. Following the advent of the myocutaneous flap, this has been very much the mainstay in intraoral reconstructive surgery. Although it has proved to be a reliable flap it has certain innate disadvantages which can often be attributed to the skin component of the flap. This paper attempts to make a case for using muscle-only pedicle flaps such as pectoralis major, masseter transfer and latissmus dorsi flaps.

7 patients with primary malignant melanoma of the oral mucosa treated during the past 15 years by extensive resection, and simultaneous neck dissection in 3 of them, are reported. 4 patients died. However, most of the patients stayed alive relatively long postoperatively.

A case of inverted papilloma (Ringertz tumour), which presented as a palatal swelling, is reported. The tumour involved the antral and nasoethmoidal complex. An approach to reconstruction of the palate after removal of the tumour is described.

The use of the masseter muscle cross-over flap is described for reconstruction in the floor of mouth, retromolar trigone, lateral pharyngeal wall and posterior palate areas. Various modifications are described which increase the versatility of this readily available flap. Case reports are used to illustrate the applications of this flap.

The functional deformity following removal of the maxilla is considerable. Rehabilitation used to be very difficult with prostheses or traditional flaps. Temporalis muscle flaps have been described for reconstruction following hemi-maxillectomy, but not total maxillectomy. A case is now presented to illustrate the use of bilateral temporalis muscle flaps following almost total removal of the maxilla at a Le Fort I level.

A case of a spindle cell lipoma of the hard palate of a 58-year-old male is reported. The histologic diagnosis is discussed. Conservative surgical removal is the treatment of choice.
