Over the last 20 years, the number of stapes operations performed has decreased steadily. This inadequate exposure to stapes surgery poses problems for both trainees and trainers. We retrospectively reviewed the outcomes of stapedotomy performed by a young physician at the ENT Clinic of the "A. Gemelli" Hospital of Rome. We used the technique of "one-shot" CO2 Laser stapedotomy using a titanium-Teflon piston. For data analysis, we considered the audiograms obtained 24 hours preoperatively and at the last follow-up examination (mean 45 months). Air conduction (AC) and bone conduction (BC) PTA were calculated for 0.25, 0.5, 1, 2 and 4 kHz thresholds. Air bone gap (ABG) were obtained from ACPTA and BCPTA. Postoperative hearing gain was calculated from the ABG before the operation minus the ABG at late follow-up examination. Analysis of outcomes did not show a clear endpoint for the learning curve; complete closure of the ABG was obtained in a large number of patients at the beginning followed by patients who showed a higher ABG. Fortunately, we did not observed any "dead ear". The study supports a learning curve in stapes surgery, but the results can vary widely among surgeries with excellent results followed by others that are not fully satisfactory. Stapes surgery should not be one of the first ear surgeries performed by a young otologist due to the functional outcome expected by patients and the lack of necessary surgical skills.Il numero di interventi per otosclerosi è progressivamente diminuito nel corso degli ultimi 20 anni. Questa riduzione crea difficoltà sia al chirurgo esperto ma soprattutto a quello giovane che inizia il suo percorso di formazione. Abbiamo analizzato in maniera retrospettiva i risultati funzionali ottenuti dopo stapedotomia effettuati da un giovane chirurgo presso la Clinica Otorinolaringoiatrica del Policlinico “A. Gemelli” di Roma. La tecnica impiegata è quella della stapedotomia con laser CO

SUMMARY In this series of patients, the underlay or overlay positioning of a graft achieves successful outcome for both repair of perforation and hearing function, with better hearing gain in the underlay group. In myringoplasty, the two most common techniques for positioning the graft relative to the remnant of both the tympanic membrane and the annulus are the "overlay" and the "underlay" techniques. 115 patients who underwent myringoplasty for tympanic membrane perforation secondary to chronic otitis media and/or trauma were included, and hearing function was evaluated. We prefer an overlay technique in subtotal perforations, in those involving the anterior and antero-inferior parts of the ear drum with respect to the handle of the malleus and in revision surgery. We reserve an underlay technique for smaller perforations and for those limited to the posterior part of the tympanic membrane. Of 115 cases, 63 underwent an overlay myringoplasty and 52 underlay myringoplasty. In the former group, five cases were anatomically unsuccessful, whereas in the second group there were three failures. The air bone gap improved significantly in both groups with a better hearing gain in the underlay group.

We reviewed our series of surgeries for paediatric cholesteatoma to assess outcomes and functional results considering the extension of disease and surgical techniques. Between January 2003 and December 2009, 36 patients (range 6-14 years) were operated on for cholesteatoma. We considered the sites involved by the cholesteatoma (mastoid, antrum, attic, middle ear, Eustachian tube), surgical techniques used (intact canal wall, canal wall down) and how our habits changed over the years; moreover, we evaluated ossicular chain conditions and how we managed the ossiculoplasty. As outcomes, we considered the percentage of residual and recurrent cholesteatoma for each technique and hearing function (air bone gap closure, high frequencies bone conduction hearing loss) at follow-up. Intact canal wall was performed in 20 patients and canal wall down in 13 patients, in 9 as first surgery. In both groups, we observed improvement of the air bone gap; in the intact canal wall group, a residual cholesteatoma was observed in 6 patients whereas, during follow-up, 2 patients who underwent a canal wall down showed a recurrent cholesteatoma that was treated in an outpatient setting. Eradication of cholesteatoma and restoration of hearing function in paediatric patients present unique surgical challenges. Our experience shows an increased choice of intact canal wall over the years. Therefore, it is important for the surgeon to counsel parents about the probable need for multiple surgeries, especially if an intact canal wall mastoidectomy is performed.Abbiamo analizzato i risultati nella nostra casistica riguardo al trattamento chirurgico del colesteatoma in età pediatrica considerando l'estensione della patologia e la tecnica chirurgica impiegata. Nel periodo compreso tra gennaio 2003 e dicembre 2009 abbiamo trattato 36 bambini e nell'analisi abbiamo valutato le sedi coinvolte dal colesteatoma (mastoide, antro, attico, cassa del timpano, tuba di Eustachio), la tecnica chirurgica impiegata (timpano plastica chiusa e aperta) e come il loro impiego si sia modificato nel corso degli anni; inoltre abbiamo valutato le condizioni della catena ossiculare e come abbiamo effettuato l'ossiculoplastica. Nell'analisi dei risultati abbiamo valutato il colesteatoma residuo e ricorrente per ciascuna tecnica e la funzionalità uditiva (riduzione dell'ipoacusia trasmissiva, ipoacusia neurosensoriale per le alte frequenze). La timpanoplastica chiusa è stata effettuata in 20 pazienti mentre quella aperta in 13 e per 9 di questi come primo intervento. Con entrambe le tecniche abbiamo ottenuto una riduzione dell'ipoacusia trasmissiva; un colesteatoma residuo è stato individuato in 6 pazienti trattati con timpanoplastica chiusa, mentre 2 patienti sottoposti a timpanoplastica aperta hanno presentetato durante il follow-up un coclesteatoma ricorrente. L'eradicazione del colesteatoma e il ripristino della funzionalità uditiva presentano maggiori problematiche nell'età pediatrica. La nostra esperienza fa emergere un maggior impiego della timpanoplastica chiusa nel corso degli anni. Perciò è importante che il chirurgo informi i genitori della possibilità di dover ricorrere a più interventi chirurgici durante la crescita del bambino, qualora si opti per una tecnica chiusa.

Meningoencephalic herniation (MEH) in the middle ear and mastoid is a rare pathological entity with possible life-threatening complications. We treated 24 patients with a trans-mastoid approach, and the bony defect was closed by heterologous materials positioned in a multilayer fashion. The cause of the bony defect were chronic otitis media with cholesteatoma, iatrogenic, spontaneous and post-traumatic. The major presenting symptoms were meningitis, headache, conductive hearing loss, cerebrospinal fluid (CSF leak), neurologic deficit and pneumoencephalus, and stenosis of a canal wall down cavity. During follow-up, no patient developed complications due to surgery or related to the pathology, and imaging showed a stable occlusion of the bony defect. Different surgical treatments have been proposed to repair MEH, and the choice is based on the localization and size of the bony defect, preoperative auditory function and the presence of a coexisting pathology. We propose the use of collagenous membranes and bone substitutes for reconstruction of the floor of the middle fossa.Le ernie meningoencefaliche nell'orecchio medio e nella mastoide rappresentato una rara entità patologica con complicanze anche mortali. Abbiamo operato 24 pazienti con un approccio trans-mastoideo e abbiamo chiuso il difetto osseo utilizzando più strati di materiale eterologo. Nella nostra casistica il difetto osseo era stato causato nel 42% dei casi da un'otite cronica colesteatomatosa, nel 33% da causa iatrogena, nel 17% il difetto era spontaneo e infine nell'8% post-traumatico. I principali sintomi sono stati: meningite, cefalea, ipoacusia trasmissiva, fistola liquorale, deficit neurologici e pneumoencefalo, stenosi di cavità di timpanoplastica aperta. Durante il follow up nessun paziente ha presentato complicanze legate alla chirurgia o correlate alla patologia e le indagini radiologiche hanno evidenziato una stabile chiusura del difetto osseo. Numerose tecniche chirurgiche sono state proposte per la risoluzione di questa patologia e la scelta si basa sulla localizzazione e la grandezza del difetto osseo, la funzione uditiva e la presenza di patologie concomitanti. Riteniamo pertanto che la tecnica da noi proposta, che si basa sull'utilizzo di una membrana di collagene e di un sostituto osseo, possa essere adatta per la riparazione del pavimento della fossa cranica media e per la risoluzione di questa patologia.

The authors report a clinical case of gas gangrene in a rare anatomic location in a 79-year-old woman, admitted because 3 days earlier she had developed a painful swelling with erythematous cutis in her right iliac fossa and suffered from a seriously increasing fever. The physical examination showed a large area of gas gangrene. In accordance with international literature, excellent results have been obtained by adopting an early multiple therapy (including surgical debridement, intensive therapy, antibiotic treatment and hyperbaric oxygen treatment).

Flexible fibroscopy is the method of choice in the diagnosis of upper airway (UA) pathologies. Some Authors believe that it should be carried out under local anaesthesia even in children less than one year of age. In this article, the Authors report on their experience with general anaesthesia, using an airway mask that simultaneously allows the flexible endoscope to be inserted and the patient to be ventilated. The study was carried out in the period 2000-2001 in 32 subjects, 18 males and 14 females between 2 and 12 months of age who presented different degrees of stridor and dyspnoea. 18 patients were affected by laryngomalacia, 6 presented bilateral paralysis of the vocal cords, 3 had a paralysis of the left vocal cord, 3 were suffering from congenital anomalies of the epiglottis and 2 had normal larynx from the point of view of morphology and motility. The method described is easy to perform and allows the subglottid area to be carefully evaluated, prolonging, if necessary, procedure time without risking hypoventilation-induced hypoxemia; carrying out the examination on a sedated patient furthermore reduces the likelihood of complications. The Authors therefore recommend that in all infants under one year of age, endoscopy of the upper airways be effected under general anaesthesia with an airway mask, reserving the execution of the same procedure under local anaesthesia to cases involving older children.

Background Management of vestibular schwannoma (VS) is a complex process aimed at identifying a clinical indication for fractionated stereotactic radiotherapy (sRT) or radiosurgery, microsurgical resection, or wait and scan (WS). We describe the experience of our VS multidisciplinary team (MDT) at a tertiary university referral center created for diagnosis, treatment, and follow-up of VS patients. Methods We conducted a retrospective study on 132 consecutive patients referred to the MDT and managed by observation (WS), microsurgery, or fractionated sRT. The analysis included patient age, tumor size, hearing level, facial nerve function, tumor control, complications, and quality of life questionnaires. Results Among the patients, 21% were subjected to microsurgery, 10% to sRT, and 69% to WS. The median follow-up time was 30 months. Outcomes based on different management modalities are described. Statistically significant differences among groups were detected in terms of quality of life (physical domain). Conclusions MDT may provide the best individualized therapy for VS patients compared with a single gold-standard strategy.

Objective: To investigate the role of inflammation in non-allergic rhinitis (NAR) patients in a large series to establish the prevalence of different NAR-subtypes, clinical features and the role of nasal cytology in the diagnostic algorithm. Methodology: Patients were selected out of 3650 individuals who spontaneously presented at our institution. We consecutively enrolled 519 NAR-patients in an analytical cross-sectional study between November 2007 and June 2013 (level of evidence: 3b). All patients underwent rhinological evaluation including symptoms questionnaire, endoscopy, CT scan, allergy tests and nasal cytology. Results: The inflammatory cell infiltrate affects the severity of symptoms differently, allowing for identification of different phenotypes of NAR. We distinguished two groups: “NAR without inflammation”(NAR-) and “NAR with inflammation”(NAR+), in addition to different NAR-subtypes with inflammation. A significant difference was observed in terms of clinical symptoms and association with comorbidities (previously diagnosed asthma and aspirin intolerance) between NAR–, NAR+ and between different NAR+ subtypes. Conclusion: Our data suggest that NAR- and NAR with neutrophils behave similarly, showing lower symptom score values and a lower risk of association with comorbidities compared to NAR with eosinophils and mast cells (singularly or mixed). In our belief it is very important to establish the presence and type of inflammation in non-allergic rhinitis patients and nasal cytology is a very useful test in correct differential diagnosis.

A number of studies have shown that cisplatin and gentamicin ototoxic effects may result from free radical-mediated damage due to the reduction of antioxidant substances and an increased lipid peroxidation. The authors summarize the results obtained evaluating the auditory and vestibular functions and the inner ear hair cell morphology and survival after administration of antioxidant agents against cisplatin and gentamicin. In the first experiment, albino guinea pigs were treated with gentamicin (100 mg/kg per day, i.m.) alone or gentamicin (100 mg/kg per day, i.m.) plus alpha-tocopherol (100 mg/kg per day, i.m.) for 2 weeks. In a second experiment, albino guinea pigs were injected with cisplatin (2.5 mg/kg per day) or cisplatin (2.5 mg/kg per day) plus tiopronin (300 mg/kg) for 6 days. Electrocochleographic recordings were made from an implanted round window electrode. In all experiments compound action potentials (CAPs) were measured at 2-16 kHz. Changes in cochlear function were characterized as CAP threshold shifts. To evaluate vestibular function, the animals underwent sinusoidal oscillations in the dark about their vertical and longitudinal axes to evoke horizontal and vertical vestibulo-ocular reflexes (VOR). Frequency stimulation parameters ranged from 0.02 to 0.4 Hz and peak-to-peak amplitude was 20 degrees. Morphological changes were analysed by light microscopy and scanning electron microscopy. Both hearing loss and vestibular dysfunction induced by gentamicin were significantly attenuated by alpha-tocopherol. However, tiopronin co-therapy slowed the progression of hearing loss in cisplatin-treated animals and significantly attenuated the final threshold shifts. Cisplatin had little effect on the hair cells of cristae ampullares and maculae. Vestibular function was completely preserved in tiopronin co-treated animals. In conclusion, antioxidants such as alpha-tocopherol or tiopronin interfere with gentamicin and cisplatin damage and this suggests that they may be useful in preventing oto-vestibulotoxicity. Therefore, it is important to develop protective strategies that permit the avoidance of the toxic side effects of these drugs without interfering with their therapeutic effects.

The aim of the present study was to investigate both vestibular and cochlear cisplatin toxicity. Twelve albino guinea pigs were divided into an experimental (n=8) and a control saline group (n=4) and were treated with cisplatin at a daily dose of 2.5 mg/kg for 6 consecutive days. Vestibular dysfunction was evaluated by computing the gain of the vestibular ocular reflex (VOR) evoked by stimulation in the horizontal (HVOR) and vertical (VVOR) planes. Changes in cochlear function were characterised as compound action potential threshold shifts. After the functional testing, tympanic bullae were removed and processed for morphological examination of the sensorineural epithelium. The onset of vestibular functional impairment was observed on the third day, although the VOR gain decrease was not significant. The impairment of the vestibular function progressed until the sixth day becoming statistically significant particularly at VVOR mid frequencies of stimulation. At these frequencies both macula and crista ampullaris functions are involved. Concomitantly a progressive auditory threshold shift was observed at all stimulus frequencies. The decline of the auditory function was statistically significant from the third day of treatment and it was more evident at high frequencies. Morphological observations showed a massive loss of outer hair cells and a degeneration of the organ of Corti in the basal/middle turns and only a slight loss of hair cells of the cristae ampullares and maculae. In conclusion, functional and morphological data provide evidence that the toxic effect of cisplatin is more pronounced in the organ of Corti than in the vestibular epithelium.
