Alar cinch sutures in orthognathic surgery: scoping review and proposal of a classification.

Orthognathic surgery and the Le Fort I osteotomy result in noticeable alterations to the nasal/nasolabial anatomy. The alar base cinch technique is a surgical technique to control lateralization of the base of the nose and is well described in the literature. The aim of this scoping review was to identify every unique alar cinch suture technique reported in orthognathic surgery and to propose a classification for the different techniques described. A search was conducted in the PubMed, Cochrane Library, and Scopus electronic databases covering the period May 1980 to July 2020, which identified 10 articles that were eligible for this review. Among these, there were several proposals for modifications to the technique, and different studies to show the effectiveness of one type among all others. Despite observing multiple techniques and variations of these while performing this review, the lack of a classification for alar cinch suture was noticed. Therefore, we propose a classification of the alar cinch suture that includes four types, which cover all of the cinching techniques described. It is believed that the use of a standardized classification may be useful to avoid duplicate publishing of techniques and to set a standard for further studies.

Impact of COVID-19 epidemic on maxillofacial surgery in Italy.

Maxillofacial departments in 23 surgical units in Italy have been increasingly involved in facing the COVID-19 emergency. Elective surgeries have been progressively postponed to free up beds and offer human and material resources to those infected. We compiled an inventory of 32 questions to evaluate the impact of the SARS-COV2 epidemic on maxillofacial surgery in 23 selected Italian maxillofacial departments. The questionnaire focused on three different aspects: the variation of the workload, showing both a reduction of the number of team members (-16% among specialists, -11% among residents) due to reallocation or contamination and a consistent reduction of elective activities (the number of outpatient visits cancelled during the first month of the COVID-19 epidemic was about 10 000 all over Italy), while only tumour surgery and trauma surgery has been widely guaranteed; the screening procedures on patients and physicians (22% of maxillofacial units found infected surgeons, which is 4% of all maxillofacial surgeons); and the availability of Personal Protective Equipment, is only considered to be partial in 48% of Maxillofacial departments. This emergency has forced those of us in the Italian health system to change the way we work, but only time will prove if these changes have been effective.

Orofacial pain evaluation in children.

AIM: Pain evaluation in children and its diagnosis are problems not always easy to solve. Children, because of their immaturity, are not always able to well communicate or to describe the clear characteristics of the disease by which they are affected. Moreover, they are often unable to report the real intensity of the pain they experience. These problems are related to their immature, not fully evolved psyche. Such problems can create difficulties to the physician who is called to examine and evaluate the origin of orofacial pain, as well as hesitation regarding when it could be necessary to start a drug therapy. Aim of this work is to propose the basic tools for the evaluation and measurement of pain that are better suitable for children, as these instruments can be used together with an accurate anamnesis and a meticulous examination, in order to formulate a precise differential diagnosis among the pathologies that affect the head and neck. A list of the most common painful diseases affecting this area is also presented. METHODS: A systematic literature review about the methods for evaluation and measurement of pain in children was conducted. The commonly used scales of measurement were examined: VAS, VSN, CAS, FPS and the Oucher SCALE. The different pathologies of head and neck and their characteristics are described and the possible causes of orofacial pain have been divided into extracranial and intracranial, in order to easily direct diagnosis. RESULTS: Orofacial pain in children is an issue of great interest in consideration of its high frequency in paediatric dentistry. Its measurement and evaluation is possible despite the small compliance of paediatric patients. Thanks to the modern technique and knowledge this evaluation can be realistic and reproducible. CONCLUSION: Evaluation scales of pain are suitable at any age and skill of the child and, together with a careful anamnesis and a proper clinical examination, allow the clinician to conduct a precise differential diagnosis of the pain so as to set the ideal therapy for the little patient.

Tunnel technique through three vertical buccal incisions to reduce nasolabial changes due to surgically assisted rapid palatal expansion.

The aim of this technical note is to present a minimally invasive approach to the maxilla for segmental Le Fort I osteotomy in surgically assisted rapid palatal expansion (SARPE). This approach reduces the nasolabial changes that occur with the traditional circumvestibular approach.

Pedicled palatal flap for surgical repair of oro-nasal fistula.

Oronasal fistula can occur secondary to various pathologies, but cleft surgery is the most common. The authors propose a pedicled palatal flap technique for surgical repair of small oronasal fistula (0.5-0.8 cm), derived from their experience in the treatment of 7 patients between March 2003 and December 2007. In one case, the fistula was induced by prolonged snorting of cocaine. In the other cases, the fistulas developed after excision of a benign tumor of the palate. For the cocaine-induced fistula, failure of the repair attempt was apparent within 7 days of surgery. In all other cases, complete fistula closure was obtained, and no complications occurred.

Remodeling the neck and the lower jaw with dehoxycholate injections.

Nonsurgical cosmetic facial procedures have gained popularity in recent decades. These procedures are commonly referred to as facial rejuvenation, and only a few are performed in the neck region. Herein, the authors describe their experience with off-label use of deoxycholic acid (DC) injections on 18 patients for remodeling of the neck and lower jaw. The injection protocol was personalized for each patient, and lidocaine was always premixed with the DC. After the initial injection visit, at least 3 months passed before further injections were considered. All documented side effects, including swelling and dysesthesia, resolved spontaneously. All patients received follow-up for at least 3 months, and only 2 patients required a second session of injections. By personalizing the injection protocol for each patient, good outcomes were achieved, including aesthetic enhancement of the shape and contour of the jaw and neck. Although the study is limited by the relatively small sample size, the results are promising and warrant additional investigations.

Influence of Kinesiologic Tape on Post-operative Swelling After Orthognathic Surgery.

INTRODUCTION: Orthognathic surgery involves making several osteotomies that lead to varying degrees of post-operative swelling. The use of KT may be beneficial for postoperative treatment after head and neck surgery, accelerating drainage of tissue reaction or haemorrhages. The goal of this study was to find out if the application of KT prevents or improves swelling, pain and trismus after orthognathic surgery, improving patients' postoperative quality of life. MATERIALS AND METHODS: In this double-blinded, randomized, control trial, 24 patients in whom bimaxillary orthognathic surgery was indicated, were included. Before surgery each patient alternatively was randomly included in the study group (treated with K-Taping(®) and corticosteroid) or in the control group (treated with corticosteroid). In the present study a MakerBot(®) Digitizer 3D™ was used to assess accurate volume measurements. All swelling measurements were expressed as total 3-D area of the landmarks (cm(2) ) in T0 pre-operative, T1 fourth day after surgery. RESULTS: The differences T0-T1 are highly significant (p < 0.01) between group 1 or study group (treated with K-taping(®)) and group 2 (control group). DISCUSSION: The use of KT appears promising, because it is simple to carry out, less traumatic, economical, can be performed everywhere in the world, free from side effects on the body. Even when swelling persists, KT gives patients the impression of a minor swelling detracting them from their pain and morbidity. Further studies have to be performed to find out if KT can reduce or replace the need for additional medications such as the use of steroids.

A Prospective, Randomized, Double-Blind, Placebo-Controlled Clinical Trial Comparing the Efficacy of Anti-edema Drugs for Edema Control in Orthognathic Surgery Using Digitizer 3-D to Measure Facial Swelling.

INTRODUCTION: Orthognathic surgery involves making several osteotomies. Any osteotomies leads to varying degrees of post-operative swelling. The aim of this study was to evaluate the effectiveness of anti-edema drugs for the control of edema, using Digitizer 3D™ for measuring soft-tissue thickness, in patients who underwent bimaxillaryorthognathic surgery. MATERIALS AND METHODS: In this double-blinded, randomized, control trial, 24 patients (study group: 12 patients, control group: 12 patients) in whom bimaxillary orthognathic surgery was indicated, were included in this study. All swelling measurements were expressed as total 3-D area of the landmarks (cm(2)) in T0 pre-operative, T1 first day after surgery, T2 fourth day after surgery, T3 4 months after surgery. For each patient we compared, by adding left and right area, the increase of swelling between T1-T0, T2-T0 and T1-T3. RESULTS: The differences T0-T1 are highly significant (p < 0.01) between group 1 or study group (treated with Venoplant(®)) and group 2 (control group); the differences T0-T2 are significant (p < 0.05) between group 1 (treated with Venoplant(®)) and group 2 (control group). The differences T1-T3 are significant (p < 0.05) between group 1 (treated with Venoplant(®)) and group 2 (control group). DISCUSSION: The present study suggests that Venoplant(®) significantly decreases postoperative edema in orthognathic surgery, thus precluding long-term corticosteroid use.

Expression of p16 in squamous cell carcinoma of the mobile tongue is independent of HPV infection despite presence of the HPV-receptor syndecan-1.

BACKGROUND: Tongue squamous cell carcinoma (TSCC) is increasing in incidence, especially among young patients and preferably females. Infection with human papilloma virus (HPV) has been suggested as a cause of SCC in the head and neck, and the proportion of oropharyngeal cancers caused by HPV has steadily increased. METHODS: Samples from 109 patients with primary TSCC were analysed for the presence of HPV16 by in situ hybridisation and for expression of its surrogate marker p16 and the HPV receptor syndecan-1 by immunhistochemistry. RESULTS: No evidence of HPV16 DNA was observed in the tumours, although one-third showed p16 staining. There was no difference in the expression of the primary HPV receptor, syndecan-1, between TSCC and a group of tonsil SCC. CONCLUSION: Whereas p16 is expressed in some TSCCs, HPV16 is undetectable, therefore, p16 cannot be used as a surrogate marker for high-risk HPV-infection in this tumour. Despite presence of the HPV-receptor syndecan-1 in TSCC, HPV prefers the tonsillar environment. Lack of p16 associates with worse prognosis primarily in patients aged ⩽40 years with tongue SCC. The improved prognosis seen in p16-positive TSCC can be due to induction of a senescent phenotype or an inherent radiosensitivity due to the ability of p16 to inhibit homologous recombination repair.

Sialoendoscopy: a viable treatment for I(131) induced sialoadenitis.

To evaluate the viability, efficacy, and safety of sialoendoscopy for the diagnosis and management of radioiodine I(131-) related sialoadenitis, we retrospectively reviewed 30 patients referred between September 2007 and July 2013 from the Thyroid Surgery Unit to the Maxillofacial Unit of the Second University of Naples Hospital with persistent sialoadenitis after treatment with I(131). After the affected gland had been isolated, the endoscope was introduced into the duct under local anaesthesia with 2% lignocaine and continuous lavage with isotonic saline, and was advanced until it reached the ductal system. We studied 24 women and 6 men, mean (SD) age 52 (??) years. In 25 patients I(131) was given for papillary (83%), in 3 for medullary (10%), and in 2 for follicular thyroid carcinoma (7%). Stenosis alone was found in 30 glands (40%), mucous plugs alone in 35 (47%), and mucous plugs, stenosis, and kinks in 10 (13%). Of the 75 glands, dilatation of the ducts was successful in 70, and we completely removed all mucous plugs and kinks. We achieved symptomatic improvement in 23 patients (77%) during a follow-up ranging from 2 weeks to 84 months. Sialoendoscopy is a viable technique for the diagnosis of obstructive salivary disease, and is a safe and effective way to treat sialoadenitis, the most common complication of treatment with I(131).

Dynamic evaluation of benign neoplasm of parotid glands with multidetector row CT.

AIM: The aim of this paper was to evaluate the role of net-enhancement (NE) of benign salivary glands with multiphase multidetector row CT (MDCT). METHODS: Forty-eight patients (M=27, F=21), aged 35-76 years old (mean =57) with benign parotid neoplasms were examinated with 4 MDCT, at 20'', 40'', 70'' e 9' after intravenous administration of contrast medium. NE was calculated after subtracting precontrast phase to postcontrast phases. Final data were compared to the histopathology. RESULTS: Thirty-six cases were pleomorphic adenomas (PA), 24 Warthin (WT). PA had a medium NE values of 23 HU, 74 HU, 53 HU e 34 HU at 20'', 40'', 70'' e 9' respectively. WT had a medium NE of 52 HU, 54 HU, 40 HU e 39 HU respectively at the same times. After subtracting precontrast phase to the delayed phase, with NE at 9' and cut-off of 34 HU, we have differenziate PA from WT and normal gland with specifity (SP) 87%, sensibility (SE) 60%, positive predictive value (PPV) and negative predictive value (NPV) of 75% and 59%; with NE at 20'' and cut-off of 54HU we have distingueshed WT from AP with SP 83%, SE 50%, PPV 75% and NPV 63%. CONCLUSION: The study of NE can allow the characterization of benign parotid gland tumors.

Polyacrylamide gel for facial wasting rehabilitation: how many milliliters per session?

BACKGROUND: Facial lipoatrophy is most distressing for HIV patients in pharmacologic treatment. Nonabsorbable fillers are widely used to restore facial features in these patients. We evaluated the safety and aesthetic outcomes of two samples of HIV+ patients affected by facial wasting who received different filling protocols of the nonabsorbable filler Aquamid® to restore facial wasting. METHODS: Thirty-one HIV+ patients affected by facial wasting received injections of the nonabsorbable filler Aquamid for facial wasting rehabilitation. Patients were randomly divided into two groups: A and B. In group A, the facial defect was corrected by injecting up to 8 ml of product in the first session; patients were retreated after every 8th week with touch-up procedures until full correction was observed. In group B, facial defects were corrected by injecting 2 ml of product per session; patients were retreated after every 8th week until full correction was observed. RESULTS: Patients of group A noted a great improvement after the first filling procedure. Patients in group B noted improvement of their face after four filling procedures on average. Local infection, foreign-body reaction, and migration of the product were not observed in either group during follow-up. CONCLUSION: The rehabilitation obtained with a megafilling session and further touch-up procedures and that with a gradual build-up of the localized soft-tissue loss seem not to have differences in terms of safety for the patients. However, with a megafilling session satisfaction is achieved earlier and it is possible to reduce hospital costs in terms of gauze, gloves, and other items.

Chondroid syringoma: a rare tumor of orofacial region.

Chondroid syringoma is a rare tumor arising from the major and minor salivary glands. The incidence of chondroid syringoma is reported to be <0.01% among the primary skin tumors. Eighty percent of the chondroid syringomas are seen in older patients , commonly on head and neck region and mostly on the cheek and nose. The authors report a case discussing the surgical management of a chondroid syringoma and pointing out the importance of including this tumor in the differential diagnosis of small subcutaneous nodules in the head and neck region, in middle-age male patients.

Eccrine hidrocystoma: a neoformation to be considered in differential diagnoses of facial swellings.

Hidrocystomas are relatively rare cystic skin tumors. The precise histogenetic derivation and the cellular differentiation of these tumors has been largely debated. Usually, the mean age at diagnosis of the patients with eccrine hidrocystomas (EH) is 51.6 years, 54.0 years for females and 32.5 years for males. EH develop predominantly in females (sex ratio 1:6.5). Most patients are asymptomatic; predilection sites are the lower eyelids, nose and lateral canthus. The authors report a rare case of EH of the lower face in a 57-year-old Caucasian male patient presented with mandibular asymmetry due to an asymptomatic neoformation on the left mandibular region. The present report is relevant for the clinical differential diagnoses that a submandibular lesion requires, to exclude neoplasms of osteogenic, mesenchymal, epithelial, vascular or glandular origin. In the case described the histopathological findings, characterized by the presence of partially collapsed, unilocular cyst lined by small, monomoprhous cuboidal epithelial cells with eosinophilic cytoplasm and a highly vascular, slightly edematous stroma, suggested the diagnosis of EH. The standard treatments for EH is surgical excision, which is associated with a high cure rate and a low recurrence rate. In conclusion, in case of EH in the submandibular region, a specific clinical and instrumental diagnosis is very difficult to make, and histopathological diagnosis represents the standard diagnostic procedure.

An unusual oronasal fistula induced by prolonged cocaine snort. Case report and literature review.

In the last 50 years cocaine usage has had a growing incidence worldwide. Chronic nasal abuse of this drug can cause extensive oromaxillofacial destructive process as oronasal perforation. To author's knowledge the only type of oronasal fistula in cocaine abusers that has been reported to date has been perforation of the hard palate; a case of oronasal fistulas involving another region of oral cavity, the anterior gingival sulcus, has been reported only once. In this article authors present the first case of oronasal fistula involving hard palate and the right supero-lateral vestible induced by prolonged cocaine snort described in literature, review about the better surgical management for this lesion and the relationship between chronic cocaine abuse and elevated serum levels of c-ANCA.
