ABSTRACT
OBJECTIVE: The extent to which mononuclear cells and TSH-receptor autoantibodies (TRAb) contribute to Graves' orbitopathy (GO) is not completely defined. Here we investigated the relationship between the immunohistochemical phenotype of orbital infiltrating cells and GO features in a large number of patients. METHODS: We conducted an observational cohort study in 76 consecutive patients with GO (16 men and 60 women) who underwent orbital decompression over a period of 18 consecutive months. An ophthalmological evaluation was performed in all patients, as well as immunohistochemistry for CD3, CD4, CD8, CD56 (T-cell markers), CD25 (T and B-cell marker), CD20, CD19 (B-cell markers), and CD138 (plasmacell marker) in specimens collected at decompressive surgery. RESULTS: Having established cutoff values for each marker, cell infiltrates were found in 60 patients (78.9%; CD3: 39.4%, CD4 55.2%, CD8 50%, CD56: 0%, CD25: 28.9%, CD20: 51.3%, CD19: 25%, CD138: 26.3%). Eleven (14.4%) stained exclusively for CD138 (plasmacells). Patients with CD4-positive mononuclear cells had a significantly greater GO clinical activity score (CAS) (mean difference 1.07, 95% CI - 0.33 to - 1.82, P = 0.004 by univariate, P = 0.05 by multivariate analysis). CAS as well as the remaining GO features were not affected significantly by the mononuclear cell subpopulations in multivariate analyses. CONCLUSIONS: Mononuclear cell infiltrates are present in the majority of GO patients, with a small percentage represented exclusively by plasmacells. CD4 cells exert a major role on GO activity. These findings may represent a further advancement in the comprehension of GO pathogenesis.

BACKGROUND: Intraoperative intraorbital bleeding is a rare but potentially catastrophic event that can lead even to blindness, if not treated promptly. The goal of surgery is to quickly reduce intraorbital pressure thus restoring normal visual function. Aim of our work is to propose a practical algorithm helping the surgeon in the setting of this critical event. METHODOLOGY: An Italian multi-institutional retrospective study was conducted. All the cases of intraoperative intra-orbital bleeding requiring at least some form of surgical management were analyzed. Cases simply managed conservatively were excluded from this analysis. RESULTS: Sixteen cases were collected. Of these, 12 were initially treated with a medial wall orbital decompression, while 4 were treated via a lateral canthotomy and inferior cantholysis (LCC). Ten patients recovered completely. Four patients presented post-op sequelae (diplopia, enophthalmous and/or eyelid malpositioning). Two major negative outcomes (blindness) were observed. CONCLUSIONS: Timely surgical intervention is critical. According to the setting in which the bleeding occurs, different options are available. LCC is probably the most rapid maneuver that can be done to reduce intraorbital pressure. Anyway, if the patient is still in the OR and a complete ethmoidectomy yet done we advise, as first step, to perform a medial orbital wall decompression.

BACKGROUND: Among chordoma patients, recurrent cases are by far more complex to be managed, and cranio-cervical junction (CCJ) localizations represent a particular challenge due to the complexity of the anatomical region which makes it difficult to obtain a radical resection. METHODOLOGY: We report our personal experience in treating four patients with recurrent CCJ chordoma with "personalized" multiportal and eventually multistage approaches. CONCLUSIONS: Endoscopic endonasal approaches have gained widespread acceptance and are considered the workhorse in most cases of craniocervical junction chordomas. Nonetheless, in some cases of recurrence, or in presence of very lateralized lesions/ anatomical variations midline approaches are either contraindicated or very difficult to perform. In all these cases it seems reasonable to consider a versatile strategy including different approaches, modulating the surgical needs with different answers and solutions offered by the different routes. In other words to personalize as much as possible the approach, being creative and not dogmatic.

BACKGROUND: The evolution of endoscopic skull base approaches has enabled surgeons to manage selected skull base tumors through a transnasal endoscope-assisted approach. On the other side, more extensive lesions may require a combined cranioendoscopic approach. In this paper, we analysed and compared the incidence of frontal lobe sagging after endoscopic multilayer (EM) reconstruction versus pericranial flap (PF) reconstruction. METHODOLOGY: Subjects were selected retrospectively according to specific inclusion and exclusion criteria. The degree of frontal lobe sagging after surgery was calculated based on the most inferior position of the frontal lobe relative to the nasion-sellar line defined on preoperative and postoperative imaging. A positive value signified upward displacement, and a negative value represented frontal lobe sagging. RESULTS: Twenty subjects were enrolled in our study. In the EM technique group the average frontal lobe displacement was -2,34 ± 1,55 mm. The average postoperative frontal lobe sagging was -0,45 ± 8,92 mm in subjects reconstructed with the PF. The skull base defect size correlated with the degree of frontal lobe sagging in subjects reconstructed with the PF, but not in the other group and when merging the two groups. CONCLUSIONS: In conclusion, the EM technique and the PF reconstruction showed a good reliability for the closure of anterior skull base defects. Moreover the PF seemed to prevent frontal lobe sagging but, for larger skull base defects, it could be useful to be combined with other autologous or heterologous materials to avoid the frontal lobe falling.

PURPOSE: Orbital decompression (OD) is a consolidated procedure for the treatment of exophthalmos in Graves' orbitopathy (GO). The efficacy of the various procedures remains unclear due to the variability of the techniques used. To address this issue, we performed a randomized clinical trial to compare the efficacy of two surgical techniques. The primary endpoint was the reduction in proptosis. Secondary aims were the risk of post-operative diplopia (POD) in primary gaze and other surgical complications. PATIENTS: 38 patients (76 orbits) affected with GO were enrolled and randomized into single lateral decompression (LD) (n = 19) or balanced medial plus lateral wall decompression (MLD) (n = 19). Following surgery, patients were seen for a follow-up ophthalmological evaluation at 6 months. Pre-operative diplopia in secondary gaze was present in 13/38 patients (34.2%, 8/19 treated with LD and 5/19 treated with MLD). RESULTS: The reduction of exophthalmos was greater in patients treated with MLD (5.1 ± 1.5 mm, range 2-8 mm) than in those treated with LD (3.5 ± 1.3 mm, range 1-6.5 mm) (p = 0.01). The overall incidence of POD in primary gaze was 5/38 (13.2%) and all of these patients had pre-operative diplopia in secondary gaze (5/13, 38.5%, vs patients with no pre-operative diplopia p = 0.005). Two of 19 patients (10.5%) treated with LD and 3/19 (15.8%) treated with MLD, developed POD in primary gaze, with no statistical difference between the two techniques. CONCLUSION: MLD provides a better result in terms of proptosis reduction compared to LD. The two techniques used here appear to have a similar safety profile in terms of POD. Pre-operative diplopia in the secondary gaze remains a major risk factor for development of POD.

OBJECTIVES: The aim of this study was to demonstrate in a prospective multicentre study that Barbed Reposition Pharyngoplasty (BRP) procedure is safe and effective in management of obstructive sleep apnoea/hypopnea syndrome (OSAHS) patients. DESIGN: Prospective study. SETTING: Multicentre study. PARTICIPANTS: Patients suffering from obstructive sleep apnoea. MAIN OUTCOMES MEASURES: Values of postoperative apnoea-hypopnea index (AHI), oxygen desaturation index (ODI), epworth sleepiness scale (ESS). RESULTS: 111 Barbed Reposition Pharyngoplasty procedures standing alone or as a part of multilevel surgery for OSAHS, performed between January and September 2016, were analysed in 15 different centres. The average hospitalisation period was 2.5 ± 0.5 days. The mean patient age was 46.3 ± 10.5 years. The average body mass index at the time of the procedure was 27.9 ± 3.2, and the majority of the patients were men (83%). The mean preoperative and postoperative apnoea/hypopnea index was 33.4 ± 19.5 and 13.5 ± 10.3, respectively (P < .001). The mean preoperative and postoperative ESS score was 10.2 ± 4.5 and 6.1 ± 3.6, respectively (P < .001). The mean preoperative and postoperative ODI were 29.6 ± 20.7 and 12.7 ± 10.8, respectively (P < .001). CONCLUSIONS: Patients undergoing BRP standing alone or as part of a multilevel approach for the treatment of OSAHS have a reasonable expectation for success with minimal morbidity.

BACKGROUND: The management of intraorbital lesions is challenging and it is strongly dependent to their nature, position and biological behaviour. Traditionally, the superior and lateral compartments of the orbit are addressed via lateral orbitotomy or transcranial approaches. Herein we present our preliminary experience in the management of selected supero-lateral intraorbital lesion through an endoscopic-assisted superior-eyelid approach. METHODOLOGY: All cases of intraorbital lesion treated in two Italian tertiary care referral centres using a superior eyelid endoscopic-assisted transorbital approach were retrospectively reviewed. RESULTS: Nine patients have been analysed. The aim of surgery was diagnostic in 5 cases and curative in the remaining 4 patients. Significant tissue biopsy was obtained in all the five diagnostic procedures. Complete resection was obtained in 3/4 lesions. No major intra- or postoperative complications have been observed. Mean surgical time was 68 minutes. Mean hospitalization time was 4.4 days. All patients were satisfied about the surgical procedure, as emerged by the post-operative counselling. At present, the mean follow-up time is 18 months, ranging from 11 to 25 months. CONCLUSIONS: Our preliminary results are promising with successful functional and cosmetic outcomes and reduced morbidity for the patient. This approach should be considered as an option for selected intraorbital lesions.

The current surgical trend is to expand the variety of minimally invasive approaches and, in particular, the possible application of robotic surgery in head and neck surgery. For this purpose, we explored the feasibility of a combined transcervical-transnasal approach to the posterior skull base, using the da Vinci Surgical System in 3 cadaver heads. Superb visualization of the sellar, suprasellar and clival regions was possible in all three specimens. The trocars` placement through a transcervical port made a more cephalad visualization possible, eliminating the need to split the palate. The advantages of robotic surgery applied to the posterior cranial fossa are similar to the ones already clinically experienced in other districts (oropharynx, tongue base), in terms of tremor-free, bimanual, precise dissection. The implementation of instruments for bony work will definitely increase the applicability of such a system in the forthcoming years.

BACKGROUND: The aim of this study was to illustrate the anatomy of the medial compartment of the orbit by comparing the endoscopic transnasal perspective with the external ones. METHODS: 8 orbits from 5 double-injected heads were carefully dissected. An endoscopic anterior transconjunctival dissection was performed in one orbit while an endoscopic transnasal intraconal dissection was conducted in 3 orbits. External dissections (from medial, superior and anterior perspective) were also performed. RESULTS: The role of the medial rectus muscle is emphasised. It represents the first important landmark encountered, covering all the other structures during transnasal approaches. By displacing it, the medial intraconal space with its contents becomes visible: the ophthalmic artery and related branches, the superior ophthalmic vein, the nasociliary nerve and, in the deepest part of the medial compartment, the optic nerve. CONCLUSION: The medial compartment of the orbit can be addressed transnasally. By displacing the medial rectus muscle, it is possible to gain adequate space for the instruments and to control all of the medial compartment, including the medial aspect of the optic nerve.

BACKGROUND: The aim of this study was to illustrate the endoscopic surgical anatomy of the infratemporal fossa (ITF) and upper parapharyngeal space and to provide useful landmarks by comparing transnasal perspectives with external ones. MATERIALS AND METHODS: 6 fresh double injected heads were dissected. External lateral dissection was performed through a pre-auricular skin incision while external anterior dissection started with a modified Weber-Ferguson incision. External medial to lateral dissection was performed starting from the rhinopharyngeal and pterygoid regions, after cutting the specimen in 2 halves passing through the nose. Endoscopic dissection was performed through an endonasal approach (0° and 45° scopes). RESULTS: Among all the structures identified during the dissection, the most useful landmark when dissecting the ITF in a lateral to medial direction is the lateral pterygoid muscle. In anterior approaches (mostly endoscopic) the role of the lateral pterygoid muscle is less important and the Eustachian tube (ET) represents the most important landmark to point out the upper portion of the parapharyngeal internal carotid artery (ICA). The role of the ET, in lateral dissection is, on the contrary, by far less important given the fact that it is very deep in the surgical field and that the ICA is encountered earlier during surgical approaches. Another crucial landmark during anterior endoscopic surgery is the vidian nerve because it points to the anterior genu of the internal carotid artery. CONCLUSION: The complex 3-dimensionality of the ITF and the upper parapharyngeal space needs a sound knowledge of the surgical anatomy. The role of the same landmarks changed in different approaches. The ability to orientate oneself in this complex area is related to an accurate knowledge of its anatomy through comparison of endoscopic and external perspectives.

OBJECTIVE: To evaluate the feasibility of endoscopic surgery in the management of selected nasopharyngeal cancers. Three different types of nasopharyngeal endoscopic resections (NER) are described. METHOD OF STUDY: From January 1997 to October 2008, 17 consecutive patients (mean age: 50 years) with previously untreated (5) or recurrent nasopharyngeal tumours (12) were treated with curative intent by pure endoscopic resection. The extent of surgical resection was classified as follows: type I NER: resection limited to the postero-superior nasopharyngeal wall; type 2 NER: resection superiorly extended to the sphenoid sinus; type 3 NER: resection with lateral extension including the cartilaginous portion of the Eustachian tube and parapharyngeal space. RESULTS: Type 1 NER was performed in 4 cases, type 2 in 6, and type 3 in 7. No intra- or post-operative complications were observed. Mean hospitalization time was 4 days (range: 1-7). Follow-up ranged from 10 to 138 months (mean: 41.2±38). At the time of writing, 12 (71/%) patients were free of disease, 3 (17%) alive with disease, and 2 (12%) dead of disease. CONCLUSIONS: NER is a feasible surgical technique that can be tailored in relation to tumour extension. Larger series and longer follow-up are needed to further validate the long-term results.

BACKGROUND: Ecchordosis physaliphora is a congenital, benign lesion originating from notochordal remnants along the craniospinal axis, most frequently located at the level of the clivus and sacrum. Sometimes ecchordosis physaliphora is difficult to recognise and treat, with a total of twenty-six cases described in the literature. METHODS: This study reports on three cases of previously undiagnosed ecchordosis physaliphora presenting with cerebrospinal fluid rhinorrhoea and meningitis. CONCLUSION: Endoscopic transclival or transsphenoid surgery including three-layer (fat, fascia and nasoseptal flap) reconstruction was used in all cases with complete resolution of the symptoms.

Various aetiopathological mechanisms have been postulated to be at the root of Menière's disease (MD), and some data suggest that there may be also an underlying autoimmune factor. In fact, Menière patients manifest certain characteristics that are typical of autoimmune involvement association of particular human leucocyte antigen haplotypes, the presence of antibodies against internal ear antigens. In this study, we evaluated the association between thyroid autoimmunity and MD in a non-selected group of patients. We recruited 50 consecutive MD patients and two groups as controls: group A, 82 healthy volunteers; and group B, 50 subjects suffering from acute unilateral peripheral vestibulopathy. All subjects were submitted to instrumental assessment of cochlear-vestibular function and analysis of thyroid-stimulating hormone (TSH), free triiodothyronine, free thyroxine, anti-TSH receptor antibody (TR-Ab), anti-thyroperoxidase antibody (TPO-Ab) and anti-thyroglobulin antibody (Tg-Ab) in the blood. The prevalence of autoimmune thyroiditis in group B [6/50 (12%); 66.7% TPO-Ab and 33.3% Tg-Ab] was superimposable with the healthy controls [6/82 (7%); 66.7% TPO-Ab and 33.3% Tg-Ab]. In contrast, 38% of the MD patients (P = 0.0001 versus group A and group B) had significant autoantibody levels (68.4% TPO-Ab; 15.8% TPO-Ab + TR-Ab; 10.5% Tg-Ab; 5.2% TPO-Ab + Tg-Ab). Furthermore, 14% of the MD patients were hyperthyroid under l-thyroxine therapy, while no dysfunction was seen in the control groups. Overall, our data demonstrate a significant association between MD and thyroid autoimmunity, which suggests that an autoimmune factor is involved in the aetiopathogenesis of this disease. These findings suggest that it should be useful to submit MD patients to multi-disciplinary clinical investigation.

BACKGROUND: Eosinophilic granulomatosis with polyangiitis and granulomatosis with polyangiitis show variable otorhinolaryngological involvement. Up to 14 per cent of granulomatosis with polyangiitis patients have subglottis involvement; little is known about the laryngeal involvement in eosinophilic granulomatosis with polyangiitis. METHOD: A literature review was conducted, together with a prospective cross-sectional analysis of 43 eosinophilic granulomatosis with polyangiitis patients. All patients underwent fibre-optic laryngoscopy with narrow-band imaging, and completed health-related questionnaires. RESULTS: The literature review showed only two cases of laryngeal involvement in eosinophilic granulomatosis with polyangiitis; in our cohort, no cases of subglottis stenosis were found, but local signs of laryngeal inflammation were present in 72 per cent of cases. Of the patients, 16.2 per cent had a pathological Reflux Finding Score (of 7 or higher). CONCLUSION: Laryngeal inflammation in eosinophilic granulomatosis with polyangiitis is frequent. It is possibly due more to local factors than to eosinophilic granulomatosis with polyangiitis itself. However, ENT evaluation is needed to rule out possible subglottis inflammation. These findings are in line with current literature and worthy of confirmation in larger cohorts.

Paradoxical vocal cord dysfunction is a nosographic entity that remains to be fully elucidated as far as concerns criteria required for diagnosis and underlying aetiopathogenesis. The disorder manifests with repeated episodes of acute dyspnoea associated with a series of symptoms that may include hoarseness, globus, chest pain and "shortness of breath". A retrospective analysis of cases with acute dyspnoea referred to our Department between June 2004 and June 2005 revealed 3 patients with paradoxical vocal cord dysfunction. In 2 of these 3 cases, concomitant psychiatric morbidity was observed and the third also presented gastro-oesophageal reflux. In one patient, the episodes of dyspnoea were triggered by inspiration of irritating substances. Diagnosis of the condition requires a high level of suspicion, which is confirmed by a laryngoscopic investigation that demonstrates hyperadduction of the true vocal cords and a reduction of at least 50% in the breathing space. From a therapeutic point of view, patients with paradoxical vocal cord dysfunction require, in our opinion, a multidisciplinary approach; in fact, only a team comprising otorhinolaryngologists, phoniatricians, pulmonologists, neurologists, allergologists, psychotherapists and speech therapists is capable of defining the appropriate treatment according to the clinical and psychological characteristics of each individual patient. Our results with speech therapy, focused on respiratory and speech retraining, are reported.

The treatment of choice for sudden sensorineural hearing loss is still lacking. Many drugs have been used over the years, with varying results and steroids have proven to be effective in clinical trials, albeit systemic administration is associated with untoward side-effects and cannot be used in all patients. The transtympanic approach presents two main advantages: first, it allows higher concentrations in the inner ear environment and, second, it minimizes systemic absorption. Aim of the present investigation was to establish the effectiveness of transtympanic steroid treatment for sudden sensorineural hearing loss in patients in whom conventional treatment had failed. For this purpose, a prospective, non-randomized study was designed to evaluate hearing improvement in sudden sensorineural hearing loss patients treated with transtympanic steroids. A solution of methyl-prednisolone and sodium bicarbonate was administered, via a transtympanic injection, in 10 patients. Hearing levels were evaluated before treatment and on days 1, 7 and 30, thereafter. Improvement in hearing was observed in 70% of patients, moreover, in patients not usually considered amenable to this kind of treatment. Transtympanic steroid treatment is an effective and safe option for patients with sudden sensorineural hearing loss when conventional treatment regimens have failed. Further studies are needed to define the optimal dosage, route of administration and type of steroids.

The objective of this study is to analyse the complications of orbital decompression in Graves' orbitopathy. The clinical records of 946 patients who had been operated on with orbital decompression for Graves' orbitopathy were reviewed and the intra- and post-operative complications with minimum follow-up of six months were analysed. An extensive review of the literature was carried out to compare results. In the case-series reported here the most frequent complications were: wasting of the temporal region (100%) in patients operated on using a coronal approach; permanent hypoesthesia of V2 (13%) and V1 (8%) in patients operated on with an upper eyelid incision. In only one patient was a total monolateral lesion of V2 reported. The most severe complications consisted in reduction of visual acuity in 5 patients, and CSF leak with cerebral complications in 2 patients, who were operated on with a non-endoscopic endonasal approach. Three patients had intra-operative haemorrhages and 3 patients had post-operative haemorrhages requiring further surgical intervention. The incidence of symptomatic sinusitis/mucoceles was 0.75%. In conclusion, orbital decompression carried out with endoscopic endonasal technique and via transpalpebral accesses appears to be associated with a low incidence of complications. Knowledge of the causes of the possible complications in the different surgical approaches can definitely help to reduce their incidence.

Drop attacks represent a significant problem during the natural course of Meniere's disease. They are characterized by a sudden fall to the ground without loss of consciousness. Diagnosis is clinical and based on the typical description of the patient. Involvement of vertical canal is possible during Meniere's disease and also after gentamicin application. Treatment of drop attacks is still a matter of discussion; most cases have a benign course with spontaneous remission and no treatment is necessary. In severe cases, aggressive treatment (surgical or pharmacological) is necessary. A case of drop attack associated with vertical vertigo is presented. Vestibular tests were performed in order to assess the involvement of inner ear. Caloric test and ice water test reveal no response. Vestibular Evoked Myogenic Potentials are present even after high doses of gentamicin. Drop attacks and vertical vertigo can occur after transtympanic gentamicin and can be well managed with high doses of local gentamicin.

Many types of approaches allow extra-capsular dissection in the deep parotid parenchyma in the treatment of benign tumours. A transcervical approach (TCA), transparotid approach (TPA) and a combined transcervical-transparotid approach (TPTCA) are the three main procedures performed to expose the deep parenchyma. We conducted a retrospective chart review enrolling 24 consecutive patients treated for benign tumours affecting the deep lobe of the parotid. Review of the surgical data was accompanied by careful follow-up to establish surgical morbidity, functional (Frey's Syndrome and first-bite syndrome) and aesthetical outcomes. A TPA was performed in the majority of cases; in 26% superficial parotidectomy was not required (selective deep parotidectomy). Minor's test showed a low rate of Frey's syndrome (3 cases of 23, 13%). No long-lasting first-bite syndrome was reported. Some additional procedures were easily performed in order to improve aesthetical results (rotational flap of sternocleidomastoid muscle, free abdominal fat transfer); these had the same results as selective deep parotidectomy. TCA (or TPTCA) ensures the best control of the facial nerve, providing good exposure and good functional and aesthetical results (without sparing the superficial parenchyma if additional techniques are performed with the aim of reducing skin depression in the treated area). The choice of the approach should have only the aim of safe resection and should not be influenced by aesthetical outcome; the craniocaudal level of the tumour seems to be the best indicator of the feasibility of the procedure also considering the branches of the facial nerve. In our experience, mandibulotomy can always be avoided.

The aim of this paper is to analyse, after clinical experience with a series of patients with established diagnoses and review of the literature, all relevant anamnestic features in order to build a simple diagnostic algorithm for vertigo in childhood. This study is a retrospective chart review. A series of 37 children underwent complete clinical and instrumental vestibular examination. Only neurological disorders or genetic diseases represented exclusion criteria. All diagnoses were reviewed after applying the most recent diagnostic guidelines. In our experience, the most common aetiology for dizziness is vestibular migraine (38%), followed by acute labyrinthitis/neuritis (16%) and somatoform vertigo (16%). Benign paroxysmal vertigo was diagnosed in 4 patients (11%) and paroxysmal torticollis was diagnosed in a 1-year-old child. In 8% (3 patients) of cases, the dizziness had a post-traumatic origin: 1 canalolithiasis of the posterior semicircular canal and 2 labyrinthine concussions, respectively. Menière's disease was diagnosed in 2 cases. A bilateral vestibular failure of unknown origin caused chronic dizziness in 1 patient. In conclusion, this algorithm could represent a good tool for guiding clinical suspicion to correct diagnostic assessment in dizzy children where no neurological findings are detectable. The algorithm has just a few simple steps, based mainly on two aspects to be investigated early: temporal features of vertigo and presence of hearing impairment. A different algorithm has been proposed for cases in which a traumatic origin is suspected.
