Endolymphatic duct and sac decompression: A new technique for Ménière’s disease treatment

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 efficacy of radiofrequency volumetric tissue reduction of hypertrophied inferior turbinate in simple snoring

Abstract BACKGROUND: Simple snoring represents a social problem, not only because it could affect the patient's married life, but it often goes along with sleep-disordered breathing. Chronic nasal obstruction has many sequel including snoring and the inferior turbinate hypertrophy (ITH) is its most common cause. The aim of the study is to evaluate the efficacy of video-assisted endoscopic radiofrequency volumetric tissue reduction (RFVTR) to reduce snoring in patients affected by chronic nasal obstruction due to ITH. PATIENTS AND METHODS: This prospective study was conducted over 48 habitual snoring with persistent nasal obstruction due to bilateral ITH refractory to medical management received one time RFVTR of both it. Nasal symptoms were assessed both subjectively, by Visual Analog Scale (VAS) and NOSE Scale, and objectively by videorhinohygrometer. Snoring was measured by Snoring severity rated by the bed partner, in a longitudinal fashion, using VAS. All patients were evaluated pre-operatively, and after 45th day (range 35-50 days) post-operatively. RESULTS: Thirty-two subjects completed study. All patients had significant symptomatic improvement in nasal breathing (5.53 ± 2.88 vs 1.87 ± 1.75; p < 0.05), confirmed by videorhinohygrometer values (p < 0.05). We had a significantly improvement of snoring in all patients (5.62 ± 2.80 vs 1.86 ± 1.43, p < 0.001) with a mean snoring Visual Analog Scale improvement of 77.4%. CONCLUSIONS: Based on this study and literature review, it seems that RFVTR represents a safe, minimal invasive, easy performed, and time and cost effective surgery, which may decrease symptoms of snoring in patients with ITH, at least, in short-term follow-up
