Extracorporeal septoplasty with internal nasal valve stabilisation.

Among various septoplasty techniques, the extracorporeal one is used for severe deformities of the caudal septum and consists essentially in removal of the nasal septum followed by correction of deformities. Reconstruction of the neo-septum is carried out by repositioning the septal fragments in a straight position. The disadvantages of this surgical technique are the septal haematoma, oedema of the mucosa in the valve area and some types of abnormalities of the middle third of the nose such as saddling of the dorsum. All of these conditions can be associated with various degrees of functional disorders. To prevent these possible complications, we developed a suture technique to fix the caudal portion of the neo-septum and avoid alterations or narrowing of the internal nasal valve. The purpose of this study is to describe extracorporeal septoplasty results with this suture technique in stabilising the internal nasal valve. From January 2011 to December 2013, a retrospective review of adult patients treated with extracorporeal septoplasty was performed at the ENT department of Imola Hospital. Pre- and post-operative evaluations were carried out by rhinomanometry and acoustic rhinometry. Statistical analysis was performed with commercially available software (IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp). 133 cases fulfilled inclusion criteria and were enrolled. A significant improvement was evident after surgery based on the results of rhinomanometry and acoustic rhinology. Extracorporeal septoplasty with stabilisation of the internal nasal valve is an effective and reproducible surgical technique that yields optimal functional results.

EAACI Position paper on the standardization of nasal allergen challenges.

Nasal allergen challenge (NAC) is an important tool to diagnose allergic rhinitis. In daily clinical routine, experimentally, or when measuring therapeutic success clinically, nasal allergen challenge is fundamental. It is further one of the key diagnostic tools when initiating specific allergen immunotherapy. So far, national recommendations offered guidance on its execution; however, international divergence left many questions unanswered. These differences in the literature caused EAACI to initiate a task force to answer unmet needs and find a consensus in executing nasal allergen challenge. On the basis of a systematic review containing nasal allergen challenges of the past years, task force members reviewed evidence, discussed open issues, and studied variations of several subjective and objective assessment parameters to propose a standardized way of a nasal allergen challenge procedure in clinical practice. Besides an update on indications, contraindications, and preparations for the test procedure, main recommendations are a bilaterally challenge with standardized allergens, with a spray device offering 0.1 mL per nostril. A systematic catalogue for positivity criteria is given for the variety of established subjective and objective assessment methods as well as a schedule for the challenge procedure. The task force recommends a unified protocol for NAC for daily clinical practice, aiming at eliminating the previous difficulty of comparing NAC results due to unmet needs.

High-definition video telescopic rhinoplasty.

Optical magnification has become an essential tool in rhinologic practice, especially following the popularisation of endoscopic procedures for nasal sinus surgery. We describe the use of VITOM® technology in rhinoplasty, which to our knowledge has not been reported in the international literature to date. This approach to rhinoplasty markedly improves visualisation of the surgical field, thereby improving the understanding of the procedures and enhancing the teaching environment. Since VITOM® technology works by combining the telescope with a standard endoscopic setting, video telescopic rhinoplasty may be easily and inexpensively performed in any ENT department provided with this instrumentation.

Nasal valve surgery.

The nasal valve region plays a key role in nasal breathing. In the international literature, a variety of techniques have been described to rectify nasal valve compromise, but based on the present evidence it is impossible to counsel a patient as to which technique is most effective. The aim of this study was to evaluate the results of surgery of the nasal valve through a hemitransfixion incision objectively with nasal endoscopy and rhinomanometry. The study group consisted of 54 males and 15 females with a mean age of 41.8 ± 14.4 years, (range: 21-72 years). After a mean follow-up of 8 ± 4.1 months, nasal endoscopy demonstrated the favourable effects of surgical treatment with a normalization of the nasal valve angles. Only 5 patients showed persistent nasal valve stenosis, and were scheduled for revision surgery. Preoperatively, total decongested inspiratory NARs were 0.245 ± 0.091 Pa/cm3/s and decreased significantly after the operation (p < 0.0005) to 0.154 ± 0.059 Pa/cm3/s. Similarly, preoperatively total decongested expiratory NARs were 0.188 ± 0.068 Pa/cm3/s and decreased significantly after the operation (p < 0.0005) to 0.142 ± 0.059 Pa/cm3/s. Moreover, total dilated inspiratory and expiratory NARs resulted significantly (p < 0.0005) lower than the preoperatively total decongested NARs, with a mean value of 0.120 ± 0.059 Pa/cm3/s and 0.102 ± 0.057 Pa/cm3/s, respectively. Statistical analysis did not reveal any influence of sex and age in rhinomanometric measurements. Hemitransfixion incision allowed a wide access to the whole valve area for inspection and correction of the various components. Rhinomanometry, performed in a decongested condition and after dilation test, was thus a useful diagnostic tool for the preoperative diagnosis of nasal valve obstruction and permitted to assess quantitatively the favourable effect of surgical procedures.

Extranasopharyngeal angiofibroma of nasal septum. A controversial entity.

The term extranasopharyngeal angiofibroma has been applied to vascular, fibrous nodules occurring outside the nasopharynx. The maxillary sinus is the most common site involved, while the nasal septum represents an extremely rare localization. Computerized tomography scan and magnetic resonance imaging are used to determine the tumour site and its extension. Surgical excision of the mass is the treatment of choice, and recurrence is rare. Typically, clinical characteristics of extranasopharyngeal angiofibromas do not conform with that of nasopharyngeal angiofibromas and, for this reason, these tumours must be regarded as a separate entity. Due to these different features, extranasopharyngeal angiofibromas can present a diagnostic challenge and a meticulous evaluation with a high index of suspicion is essential in establishing the correct diagnosis and treatment. We report the case of a 57-year-old female with a 1-year history of a slowly progressing right nasal obstruction due to the presence of a whitish mass adhering to the posterior nasal septum. The patient was succesfully treated surgically. Histopathological findings were compatible with a diagnosis of angiofibroma. Extranasopharyngeal angiofibroma must be taken into consideration in the differential diagnosis of nasal vascular tumours and nasal septum should be regarded as a potential, though exceptional, localization of these neoplasms.

Study of nasal valvular stenosis by means of acoustic rhinometry using ognibene internal dilator.

The nasal valve represents the main region of nasal respiratory resistance; therefore, even small deformities in this area can result in breathing disorders. A total of 93 patients (55 male, 38 female, mean age 37 years, range 16-52) suffering from nasal respiratory impairment due to valvular stenosis were recruited to study nasal function by means of rhinomanometry and acoustic rhinometry. Examinations were made in basal conditions, after decongestion and using the Ognibene internal dilator. Of these patients, 75 underwent surgery for functional correction of valvular stenosis and were observed at follow-up 3 months later, to analyse the surgical outcome. A review of the data concerning acoustic rhinometry has proven that, on the basis of post-operative tests, Minimal Cross-sectional Area values almost match pre-operative findings, carried out with nasal dilator. The aim of the present study is to demonstrate that acoustic rhinometry, associated with rhinomanometry and carried out with the aid of Ognibene internal dilator, is a valid tool for the diagnosis of nasal valvular stenosis and can also be usefully employed in post-operative follow-up.

Paroxysmal positional vertigo: short- and long-term clinical and methodological analyses of 794 patients.

Between 1995 and 2001, eight Italian clinical centres used the same diagnostic and therapeutic protocol in order to assess the clinical progress of paroxysmal positional vertigo and the benefits of an appropriate follow-up in prevention of relapse. The study population comprises 794 patients affected by paroxysmal positional vertigo. The study protocol comprised diagnostic staging including a complete otoneurological test, an anamnestic questionnaire aimed at identifying any possible risk factor, a blood test in basal conditions and monitoring of blood pressure. If necessary, more specific instrumental tests have been carried out. Appropriate rehabilitative manoeuvres were performed from 1 to 3 times within the same session. The patient was checked 3-5 days later: in the presence of a positive result, the treatment was repeated; if negative, patients were seen at clinical follow-up 7, 30, 180 and 365 days after recovery. Wherever possible, patients have been contacted 2 years after the first treatment and asked to answer a questionnaire and to attend for a clinical check-up. The incidence of paroxysmal positional vertigo appeared to be higher in females and in patients aged 50-70 years, being low in patients under 30. In 88.8% of cases posterior semicircular canals showed a significant involvement; in 6.8% of cases, only involvement of lateral semicircular canals; monolateral (2.7%) and bilateral (1.7%) multicanalar forms were rare. Paroxysmal positional vertigo forms involving posterior semicircular canals have been treated with Semont (simplified by Toupet), Epley, Parnes Price-Jones manoeuvres; those, involving lateral semicircular canals with Vannucchi-Vicini forced position and "barbecue" or Gufoni manoeuvre. Whilst all these manoeuvres were equally effective, longer recovery times have been observed in paroxysmal positional vertigo forms involving lateral semicircular canals when the Vannucchi-Vicini forced position was ineffective. Any relapses have been evaluated at least 15 days after a negative clinical pattern. Possible involvement of other semicircular canals (recurrence) some time after the first onset has been considered separately. Follow-up at 6 months showed recurrence in 12.4% of cases, while being chronic in 1.5% of cases. Only 9.3% of cases showed recurrence at 6 months, no statistically significant difference being observed between vertical (8.9%) and lateral canal (9.6%), forms. Relapses occurred in 3.1% of cases, in one third of which at least two risk factors were detected.
