The role of the nose in snoring and obstructive sleep apnoea: an update

Multilevel anatomic obstruction is often present in snoring and obstructive sleep apnoea (OSA). As the nose is the first anatomical boundary of the upper airway, nasal obstruction may contribute to sleep-disordered breathing (SDB). A number of pathophysiological mechanisms can potentially explain the role of nasal pathology in SDB. These include the Starling resistor model, the unstable oral airway, the nasal ventilatory reflex and the role of nitric oxide (NO). Clinically, a number of case–control studies have shown that nasal obstruction is associated with snoring and mild SDB. However, there is not a linear correlation between the degree of nasal obstruction and the severity of SDB, while nasal obstruction is not the main contributing factor in the majority of patients with moderate to severe OSA. Randomised controlled studies have shown that in patients with allergic rhinitis or non-allergic rhinitis and sleep disturbance, nasal steroids could improve the subjective quality of sleep, and may be useful for patients with mild OSA, however, they are not by themselves an adequate treatment for most OSA patients. Similarly, nasal surgery may improve quality of life and snoring in a subgroup of patients with mild SDB and septal deviation, but it is not an effective treatment for OSA as such. On the other hand, in patients who do not tolerate continuous positive airway pressure (CPAP) well, if upper airway evaluation demonstrates an obstructive nasal passage, nasal airway surgery can improve CPAP compliance and adherence

The body dysmorphic disorder patient: to perform rhinoplasty or not?

By virtue of being a (primarily) aesthetic rather than a functional procedure, rhinoplasty is unique among rhinological operations. As such, it raises moral, philosophical and social issues that no other procedure does. The preoperative assessment of a rhinoplasty patient includes a number of considerations that are unique in this type of surgery; during the outpatient consultation, the patient's motivation for surgery, stability and overall psychological evaluation, with a special emphasis on body dysmorphic disorder, have to be taken into consideration. Body dysmorphic disorder is a relatively common obsessive-compulsive spectrum disorder defined by a constant and impairing preoccupation with imagined or slight defects in appearance. Body dysmorphic disorder is associated with poor quality of life, extremely high rates of suicide and—following cosmetic surgery—high rates of dissatisfaction, occasionally manifesting as aggressiveness. A combination of psychological and medical management is the treatment of choice and this review aims to address the frequently controversial rhinoplasty indications for these patients

Endoscopic nasal versus open approach for the management of sinonasal adenocarcinoma: a pooled-analysis of 1826 patients

Surgical resection represents the gold standard for the treatment of sinonasal malignancies. This study reviewed the published outcomes on endoscopic surgery or endoscopic-assisted surgery versus open approach for the management of sinonasal adenocarcinomas

Role of Echocardiography in Percutaneous Mitral Valve Interventions

Intraprocedural imaging continues to evolve in parallel with advances in percutaneous mitral valve interventions. This didactic review uses several illustrations and rich intraprocedural videos to further describe and demonstrate the role of the most up-to-date echocardiographic and advanced imaging technologies in the patient selection and intraprocedural guidance of percutaneous mitral valve interventions. We will focus on 3 interventions: 1) percutaneous balloon mitral valvuloplasty for mitral stenosis; 2) transcatheter edge-to-edge repair of mitral valve regurgitation; and 3) transcatheter closure of periprosthetic mitral regurgitation. In addition, we discuss potential pitfalls of 3-dimensional transesophageal echocardiography and show examples of this technique

Biphenotypic sinonasal sarcoma: European multicentre case-series and systematic literature review [Sarcoma bifenotipico nasosinusale: case-series europeo multicentrico e revisione sistematica della letteratura]

Obiettivo: Il sarcoma nasosinusale bifenotipico (SNSB) è un raro tumore a basso grado, incluso a partire dalla 4° edizione WHO dei tumori testa-collo. L’obiettivo di questo studio è analizzare i tassi di sopravvivenza e i pattern di recidiva di questa neoplasia. Metodi: Revisione retrospettiva dei pazienti affetti da SNSB, trattati mediante approccio endoscopico in 6 centri di riferimento europei. È stata condotta inoltre una revisione sistematica della letteratura dal 2012 ad oggi, secondo le linee guida PRISMA. Risultati: . Sono stati inclusi 15 pazienti (approccio endoscopico endonasale in 7 casi, craniectomia endoscopica transnasale in 4 casi, approccio combinato transcranico in 4 casi). In 2 casi è stata somministrata radioterapia adiuvante. Dopo un periodo di follow-up medio di 27,3 mesi, è stato riscontrato un caso di metastasi a distanza; i tassi di 5-year Overall Survival e Disease-Free Survival erano 100% e 80 ± 17,9%, rispettivamente. Conclusioni: . Il SNSB è un tumore localmente aggressivo con un basso tasso di recidiva e tassi di sopravvivenza incoraggianti se trattato con asportazione chirurgica radicale con radioterapia adiuvante per casi selezionati. La chirurgia endoscopica ha dimostrato di essere sicura ed efficace come trattamento iniziale all’interno di un protocollo di cura multidisciplinare.Objective: Biphenotypic sinonasal sarcoma (BSNS) is a rare low-grade cancer that was included from the 4th edition of WHO classification of head and neck tumours. The purpose of this study is to analyse clinical behaviour, pattern of recurrences and survival outcomes of this neoplasm. Methods: Retrospective review of patients affected by BSNS who were treated via an endoscopic-assisted approach in 6 European tertiary-care referral hospitals. Cases of BSNS described in literature since 2012 to date were fully reviewed, according to PRISMA guidelines. Results: A total of 15 patients were included. Seven patients were treated via an endoscopic endonasal approach, 4 with endoscopic transnasal craniectomy, and 4 via a cranio-endoscopic approach. Adjuvant treatment was delivered in 2 cases. After a mean follow-up of 27.3 months, systemic metastasis was observed in 1 case; the 5-year overall survival and disease-free survival rates were 100% and 80 ± 17.9%, respectively. Conclusions: BSNS is a locally aggressive tumour with a low recurrence rate and encouraging survival outcomes if properly treated with surgical resection and free margins followed by adjuvant radiotherapy for selected cases. Endoscopic-assisted surgery is safe and effective as an upfront treatment within a multidisciplinary care protocol

Gustatory rhinitis

Purpose of review This review aims to characterize gustatory rhinitis using recent advances in pathophysiology and novel surgical and medical management strategies. Recent findings A significant amount of research has recently focused on the role of capsaicin and its receptors (TRPV1 and VR1), which can be found on sensory c-fibers in human nasal mucosa and play a critical role in the development of nasal hyperresponsiveness to environmental factors. Blocking the nasal sensory nerve stimulation (via the use of capsaicin desensitization) or outgoing parasympathetic innervation (via endoscopic Vidian neurectomy) may control nasal hyperresponsiveness and therefore prevent the induction of rhinitis symptoms. Summary Gustatory rhinitis is a conspicuous type of food-associated rhinorrhea, which can occasionally be associated with significant quality-of-life impairment. It results from an abnormal gustatory reflex associated with a hyperactive, nonadrenergic, noncholinergic, or peptidergic neural system. The use of nasal ipratropium bromide may be effective, if avoidance is not possible or successful. We have had excellent results with the use of intranasal capsaicin or endoscopic vidian neurectomy (including removal of 4-5mm of the nerve between pterygopalatine fossa and the sphenoid floor) in patients with nonallergic rhinitis, and these could potentially be used as a last resort in patients with intractable gustatory rhiniti
