Summary: Background: Multicomponent defects of the head and neck involving the cervical skin pose a reconstructive challenge for microsurgeons and usually requires two flaps. However, many patients who undergo such surgical treatment had prior treatment with radiotherapy and the availability of recipient vessels for free flap reconstruction may be limited. The purpose of this study was to review our experience in the reconstruction of these extensive head and neck defects using a single ALT free flap. Methods: A total of 21 patients with complex defects of the head and neck involving multiple anatomical subunits, including the overlying cervical skin, underwent reconstruction with a single ALT flap. The clinical, functional, and aesthetic outcomes of these patients were reviewed. Results: The mean hospital stay was 24 days. There was one total flap loss due to pedicle thrombosis. The patient underwent a further ALT reconstruction with no postoperative complications. Cervical fistulas occurred in three patients, and all fistulas were healed by simple wound packing. Three patients with tracheal defect had a functional tracheostoma with adequate stomal patency. A modified barium swallowing study was performed on each patient, and all of them achieved total oral intake. Among them, two patients tolerated only a pureed diet. Conclusions: Complex neck reconstruction can be accomplished with a single ALT flap with good clinical and functional results, minimal morbidity and quick recovery.

Closure of a tracheoesophageal puncture site performed during voice prosthesis implantation may sometimes be required. Besides local techniques, more elaborate procedures, such as closure by means of free microvascular flaps, have been advocated. In this report, we describe a case of local treatment of a hard-to-heal fistula with local application of autologous platelet-rich fibrin matrix in a 77-year-old male patient. At one-week follow-up, the size of the fistula had decreased dramatically but some leakage remained when drinking. After one month, the patient was able to drink and eat normally without any leakage. There was no recurrence of the leakage at two years' follow-up. In summary, local application of platelet-rich fibrin seems to be a simple, safe and effective procedure for tracheoesophageal fistula closure.

The presence of melanin pigment and melanocytic markers expression have been rarely reported in salivary gland tumors. Herein, two cases of carcinoma arising in pleomorphic adenoma of the parotid gland and showing diffuse expression of myoepithelial and melanocytic markers are described. The clinical-pathological clues useful in the differential diagnosis with melanoma are discussed. In addition, a review of the pertinent literature is also proposed, discussing the pathologic mechanisms potentially involved in this phenomenon.

In particular, ITH in the noncleft side can be especially problematic, because it reduces the healthy nasal area, creating bilateral nasal obstruction that might affect the growth of the maxillofacial skeleton. Although these anatomic and functional changes are documented, few recommendations have been developed regarding the proper approach to ITH. The aim of the present study was to asses the ITH severity and determine the degree of nasal airway patency in patients who have undergone primary correction of the nasal septum during lip repair compared to patients operated on without primary septal correction. METHODS: The study population included two groups. One group consisted of twenty unilateral cleft lip palate UCLP patients who have previously undergone primary rhinoseptoplasty as part of their treatment plan. The control group consisted of twenty UCLP patients operated on without rhinoseptal correction. The Nasal Obstructive Symptom Evaluation (NOSE) scale and nasal endoscopy were used to assess nasal obstruction. RESULTS: The overall untreated group reported severe symptoms across all NOSE scale dimensions more frequently than children who have undergone primary rhinoseptoplasty. The difference was statistically significant for each dimensions (p

Objective Pediatric periorbital cellulitis represents a common disease complicating a nasal infection. Methods A ten–year retrospective review of fifty-seven children admitted to our institution with the diagnosis of periorbital cellulitis as a complication of sinus infections was carried out. Results The age varied from one month to eleven years (mean 3.9 years). Thirty-five were males (62%), while twenty-two were females (38%). Nine out of fifty-seven (15.8%) presented exophthalmos associated with eyelid erythema and edema, while the rest suffered mainly from eyelid erythema and edema. Twenty-two patients complaining of exophthalmos or not responding to medical therapy within 48 h were assessed with a computed tomography scan (38.6%). A subperiosteal orbital abscess was detected in nine cases and these patients underwent surgical drainage (15,8%). Recurrence of orbital infection occurred in three cases (5.3%). Conclusions Medical management is the main treatment for both preseptal and postseptal orbital cellulitis. Nevertheless, there is no universally accepted guideline for the treatment of subperiosteal abscesses and each case should be treated accordingly. Urgent surgical drainage should be considered in cases not responding to adequate medical management, or those cases presenting visual deterioration.

Obstructive sleep apnea represents a large burden of disease to the general population and may compromise patient quality of life; workplace and automotive safety; and metabolic, cardiovascular, and neurocognitive health. The disease is characterized by repetitive cycles of upper airway collapse resulting from a lack of pharyngeal airway structural support and loss of muscle tone among upper airway dilators. Polysomnography serves as the gold standard for diagnosis of obstructive sleep apnea and the apnea-hypopnea index is the most commonly used metric for quantifying disease severity. Conservative treatments include lifestyle modification, continuous positive airway pressure treatment, and dental appliance therapy. Surgical treatment options include pharyngeal and facial skeletal surgery. Maxillomandibular advancement has been shown to be the most effective surgical approach for multilevel expansion of the upper airway and may significantly reduce an obstructive sleep apnea patient's apnea-hypopnea index. Patient age, obesity, and the degree of maxillary advancement may be key factors contributing to treatment success.

Background:Madelung's disease is a rare disorder characterised by the presence of multiple, symmetric, non-capsulated fat masses in the face, neck and other areas of upper extremities. In some cases, severe clinical complications such as upper airway compression can occur.Case report:A 56-year-old man affected by Madelung's disease complained of snoring and severe daytime sleepiness. Polysomnography revealed severe obstructive sleep apnoea. An attempt to treat sleep apnoea by continuous positive airway pressure failed because of poor compliance. Functional expansion pharyngoplasty was carried out as an initial treatment. Marked improvement of neck movements and normalisation of somnographic parameters were observed at six months’ follow up.Conclusion:Patients with Madelung's disease should be examined carefully for potential obstructive sleep apnoea. Although continuous positive airway pressure remains the treatment of choice, specific surgery can be used in those patients who cannot tolerate continuous positive airway pressure therapy.

The endoscopic bidimensional vision offered by the endoscope during endoscopic sinus surgery involves difficulty in visualizing surgical field depth which makes it difficult to learn this surgical technique and makes it necessary for the endoscopic surgeon to mentally create a three-dimensional (3D) picture of the paranasal sinuses anatomy. In particular, frontal recess surgery requires good knowledge of its anatomic position, also since it is necessary to use angled endoscopes, which distort the view, and angular instruments which are difficult to use. Purpose of this project is to offer to the endoscopic surgeon a detailed 3D model of the nose and paranasal sinuses with particular attention to the frontal recess. A 3D reconstruction of the frontal recess and its related structures, starting from computer tomography scans of the human skull, was realized using a professional 3D graphics software. A detailed reconstruction of the main structures which contribute to form the frontal recess was obtained. Particular attention was paid when reproducing the agger nasi cells, uncinate process, ethmoidal bulla, anterior ethmoidal cells, frontoethmoidal cells and their anatomic variants. This is the first experience reported in literature regarding this new technique of iconographic didactics applied to endoscopic sinus surgery. It represents a new frontier, which surpasses and integrates the previous didactic techniques to help the surgeon to mentally create a 3D image of the paranasal sinuses.

Introduction Eyelid malignant melanoma represents less than 1 % of all skin melanomas and approximately 1 % of all malignant neoplasms of the eyelid skin. Because of its relative rarity, there is a paucity of descriptive papers reporting only small series of reconstructed patients. The repair of eyelid defects represents a reconstructive challenge. Ideally, the reconstruction of the defect must guarantee function with tissue of the same color, texture, and thickness of that of the removed skin and at the same time avoid complications such as ectropion and lagophthalmos. Materials and Methods We describe a consecutive series of 11 patients affected by cutaneous melanoma of the lower lid who underwent full-thickness excision of the neoplasm and subsequent wide excision. All the patients were treated in one-stage reconstruction modality with a modified monopedicle myocutaneous flap, harvested from omolateral upper eyelid, tunneled under the lateral canthus skin and armed with a conchal auricular cartilage framework. Four patients underwent the sentinel lymph node biopsy during reconstructive procedure. No major complications were reported. In our experience, the proposed myocutaneous flap allows to obtain excellent results, both aesthetically and functionally. Conclusions This technique has the advantage of avoiding multi-staged procedures, with respect for the oncological excision indication for head and neck melanoma, decreasing the incidence of associated major complications.

Many techniques have been described in the literature for the reconstruction of congenital or acquired defects of the earlobe. Most techniques for earlobe reconstruction use adjacent tissue to compose a pedicled or bilobed flap, but usually require a two-stage procedure, or need a skin graft; more rarely reconstructive methods that led to a satisfactory result and a pleasant appearance in one-stage procedure have been described. We describe a personal and geometrical modification of the double-lobed flap according to Gavello's original technique, which allows to shape the anatomical curvature of the earlobe and to reduce the skin retraction without adding any scars or skin graft. In our opinion, the revisited reconstructive technique provides lots of advantages, improves aesthetical results and provides more natural appearance.

Background Microsurgical reconstruction has become the worldwide gold standard for repairing surgical defects in head and neck cancer. The aim of this article is to describe a standardized reconstructive approach to the oral cavity and oropharynx soft tissue defects. Patients and methods Since 1992, the authors have treated 163 patients affected by oral cavity and oropharynx cancer, performing a total of 175 flaps. A systematic postoperative functional study prompted a surgical strategy, in terms of flap choice, shape, and insetting. A two-dimensional template was used to obtain a three-dimensional reconstruction for the best functional and aesthetic outcome. To simplify preoperative planning, surgical resections were divided into a set number of classes. The templates, flap choice, and insetting are described for each region. Results Complications consisted of seven partial necroses of the flap which easily resolved with a local toilette and 12 complete necroses of the flap due to vascular thrombosis, these patients required a secondary reconstruction with another free flap. Functional results were systematically evaluated in the first 60 patients of our series with particular attention to the swallowing function, which was analyzed by both videofluoroscopy and functional endoscopic evaluation of swallowing. Results showed a good functional recovery with the described reconstructive techniques. Conclusion A standardized surgical strategy based on reproducible templates might facilitate less experienced surgeons in analyzing the problem, choosing the best technical solution and foreseeing the functional outcomes.

The interferon-inducible DNA sensor IFI16 is involved in the modulation of cellular survival, proliferation, and differentiation. In the hematopoietic system, IFI16 is consistently expressed in the CD34+ stem cells and in peripheral blood lymphocytes; however, little is known regarding its regulation during maturation of B- and T-cells. We explored the role of IFI16 in normal B-cell subsets by analysing its expression and relationship with the major transcription factors involved in germinal center (GC) development and plasma-cell (PC) maturation.IFI16mRNA was differentially expressed in B-cell subsets with significant decrease inIFI16mRNA in GC and PCs with respect to naïve and memory subsets.IFI16mRNA expression is inversely correlated with a few master regulators of B-cell differentiation such asBCL6, XBP1, POU2AF1, andBLIMP1. In contrast,IFI16expression positively correlated withSTAT3, REL, SPIB, RELA, RELB, IRF4, STAT5B, andSTAT5A. ARACNE algorithm indicated a direct regulation ofIFI16byBCL6,STAT5B, andRELB, whereas the relationship betweenIFI16and the other factors is modulated by intermediate factors. In addition, analysis of the CD40 signaling pathway showed thatIFI16gene expression directly correlated with NF-κB activation, indicating that IFI16 could be considered an upstream modulator of NF-κB in human B-cells.

The recent evolution regarding the techniques of pharyngoplasty has been focused on the concept of obtaining the expansion and stabilization of the pharyngeal airspace through the treatment of lateral pharyngeal wall (LPW) collapse rather than through ablation of the redundant pharyngeal soft tissue. The role of LPW in the pathogenesis of obstructive sleep apnea syndrome has been demonstrated by radiologic and sleep endoscopy studies and the narrowing of the LPW appears to be the sole independent risk factor for obstructive sleep apnea syndrome. The functional expansion pharyngoplasty represents a conservative modification of expansion sphincter pharyngoplasty and can be used in patients with obstruction of the upper airway due to the LPWs collapse without altering physiological functions of the upper airway, including smell, taste, swallowing, and speech.

Objective. To correlate the presence of BRAF V600E mutation with clinicopathological parameters. Study Design. Case-control study. Setting. BRAF mutation represents the most common onco- genic event in sporadic papillary thyroid cancer (PTC). There are, however, significant discrepancies regarding the overall frequency and its relationship with clinicopathological para- meters of poor outcome. We analyzed BRAF mutation in a cohort of patients affected by PTCs to identify its association with clinical variables. Subjects and Methods. We analyzed retrospectively a series of 304 patients, treated for PTC from 1999 to 2011 at Bologna University Hospital. We searched BRAF mutation by reverse transcription polymerase chain reaction (PCR) fol- lowed by PCR and direct sequencing. Results. BRAF mutation was found in 77.4% of classical PTCs, 31.9% of the follicular variant, and 72.2% of high tall cell PTCs, being significantly associated, at univariate analysis, with recurrence, stage, multicentricity, histologic subtype, extrathyroidal extension, nodule dimension, body mass index, and American Thyroid Association (ATA) risk stratification. Furthermore, higher T, but not N or M, stage was associated with BRAF mutation. In the multivariate analysis, the BRAF mutation was significantly associated only with the ATA risk stratification, in turn showing a significant negative association with recurrence-free survival time with Cox multivariate analysis. Conclusion. Our results indicate that BRAF mutation identifies a subset of PTC with increased risk of recurrence. The presence of BRAF mutation might be a valuable diagnostic and prognostic marker of the disease. To confirm the diagnostic usefulness of this marker, further studies should be carried out.

Hyoid bone fractures are rare (0.002% of all fractures) and most result from strangulation or hanging. Other causes are direct trauma, mostly traffic accidents, sports injuries, gunshots, and induced vomiting. The diagnosis is often difficult, especially when associated with other soft tissue injuries or fractures, which may seem more worthy of treatment. Only one hyoid bone fracture caused by a helmet strap in a traffic accident has been reported. The case we present is unusual. A 65-year-old male motorcycle accident victim was brought to the emergency department of our hospital. On arrival, he was awake and oriented. He had significant bleeding from the mouth and was in respiratory distress; he also had neck swelling and subcutaneous crepitus without significant pain (spontaneous or provoked by pressure). Physical examination of the neck was difficult because of the presence of an orthopedic collar; he reported painful swallowing. The skin on the chin was lacerated. No nosebleed or other skin injury was present. He had dysphonia, with a guttural, helium-like voice. The patient wore superior and inferior removable dental prostheses: the inferior one had been broken and lost during the crash, while the superior one had been damaged, but not dislodged. After removing it, no mucosal wounds were seen in the oral cavity and no blood was seen draining from the pharynx posteriorly. Because bleeding from the nose and mouth were excluded, an ENT surgeon and anesthesiologist were consulted with regard to the respiratory distress, and the patient was intubated. Subsequently, fibre optic endoscopy was used to evaluate the upper aero-digestive tract (UADT): a large laceration was found in the glossoepiglottic region, with a hyoepiglottic ligament lesion and subsequent posterior epiglottis collapse on the glottic plane (Fig. 1). As the patient was stable and could be monitored, computed tomography (CT) was performed and showed fractures of the mandibular symphysis and left condyle, thyroid cartilage, and hyoid bone bilaterally, with disarticulation of the hyoid corpus from the greater horns (Fig. 2). Significant subcutaneous emphysema of the neck was also seen. A maxillofacial surgeon was asked to evaluate the mandibular fractures. The physical examination also revealed left wrist trauma; standard X-rays showed dislocation of the lunate bone and a temporary brace was applied to immobilise the wrist.
