Oropharyngeal surgery for Obstructive Sleep Apnea (OSA) has evolved from a radical excision of "redundant" soft tissue for the enlargment of the airway to a minimally invasive reconstruction to fulfill both preservation of pharyngeal function and improvement of sleep apnea. Recently, Alianza surgical technique has been successfully introduced as a new, non-resective procedure aimed to treat concentric pharyngeal collapse at the velum using Barbed Sutures. The aim of this study was to show the effectiveness and safety of Alianza technique as standalone surgical treatment in selected patients with moderate-severe OSA and concentric pharyngeal collapse that refused or did not tolerate Continuous Positive Airway Pressure therapy.Effectiveness of the surgical procedure was assessed by means of the Epworth Sleepiness Scale (ESS), Home Sleep Test, and a 0-10 snoring VAS.At the end of our selection process, 26 patients were enrolled, with a mean age of 52.7 ± 9.2 years, that undergone Alianza tecnique. There was a statistically significant reduction in mean post-operative apnea-hypopnea indexes (34.1 ± 11.5-16.3 ± 10.3; p 0.01), mean oxygen desaturation index (29.0 ± 14.5-13.1 ± 9.2; p 0.01), and mean ESS scores (12.1 ± 5.8 and 5.8 ± 4.4; p 0.01).There was also a significant decrease in mean post-operative snoring VAS scores (7.85 ± 1.23 vs 3.2 ± 1.7, p 0.01). There were no major complications.Our preliminary results suggest that Alianza technique is a safe and repeatable surgery. Further studies on a larger scale are needed to confirm these encouraging data supporting the role of Alianza alone or in OSA multilevel surgery in selected OSA patients.

Background: The present article aims to introduce the endolymphatic duct and sac decompression technique (DASD) and to give a spotlight on its benefits in Ménière’s disease (MD) treatment. Methods: Eighty-two patients with intractable MD which met the inclusion criteria were recruited and underwent DASD. This technique allows a meningeal decompression of the duct and the sac from the posterior cranial fossa to the labyrinthine block. The authors considered as main outcomes, the change of the dizziness handicap inventory (DHI) results, with the evaluations of the three sub-scales (Functional scale, Physical scale, and Emotional scale); ear fullness and tinnitus change on the perceptions of the patient; and hearing stage with four-Pure Tone Average (500 hz-1000 hz-2000 hz-4000 hz). The differences between the preoperative and the postoperative score were evaluated. A comparison with the literature was conducted. Results: After a 14-month follow-up, patients that underwent DASD reported a remarkable improvement of the symptoms in all three functional scales, confirmed by the total DHI. The difference between preoperative and postoperative scores is statistically significant. The data describe an ear fullness and tinnitus improvement. The multi-frequency tonal average before and after the surgery does not suggest a worsening of the value for any of 82 patients. Conclusion: The modification of sac surgery includes the endolymphatic duct in the decompression area allowing inner ear functional improvement, vertigo control, ear fullness improvement with minimal risk of facial nerve paralysis, and hearing loss. DASD is an improved old surgical technique.

The use of barbed sutures (BS) for the treatment of retropalatal collapse and vibration in patients suffering from snoring and obstructive sleep apnea (OSA) has significantly increased in the last few years. Many surgeons have discovered the advantages and unique properties of the BS and allowed the popular surgical pharyngoplasty techniques to be updated and improved. A systematic review was performed to identify all the clinical studies concerning the different barbed pharyngoplasty (BP) techniques used for the treatment of palatal collapse in snoring and OSA patients. A qualitative analysis of data extracted was conducted. We included 12 studies of which 10 are prospective and 2 retrospective: 9 single-arm studies on the efficacy of a specific BP technique, 1 randomized clinical trial on the comparison between BP and control groups, and 2 studies on the correlation between two different BP techniques. To date, in the literature, 5 different types of BP techniques have been described: barbed snore surgery, barbed reposition pharyngoplasty, barbed expansion sphincter pharyngoplasty, barbed suture suspension, and barbed soft palate posterior webbing flap pharyngoplasty. All the studies showed an overall improvement in the primary efficacy parameters investigated (apnea-hypopnea index, oxygen desaturation index, and Epworth sleepiness scale) in each of the surgical techniques performed without any major complications. Given the extreme heterogeneity of the studies analyzed, it is necessary to perform more randomized and control studies on large samples aimed to define the best BP technique based on its effectiveness, surgical success rate, patient’s compliance, and complications.

Low back pain represents a significant socioeconomic burden. Several nonsurgical medical treatments have been proposed for the treatment of this disabling condition. Epidural steroid injections (ESIs) are commonly used to treat lumbosacral radicular pain and to avoid surgery. Even though it is still not clear which type of conservative intervention is superior, several studies have proved that ESIs are able to increase patients’ quality of life, relieve lumbosacral radicular pain and finally, reduce or delay more invasive interventions, such as spinal surgery. The aim of this narrative review is to analyze the mechanism of action of ESIs in patients affected by low back pain and investigate their current application in treating this widespread pathology.
