Retrolabyrinthine approach to the lateral skull base: The value of preoperative temporal bone CT analysis.

PURPOSE: The most used neurosurgical approach to reach cerebellar-pontine angle is the retrosigmoid route. This article describes the presigmoid approach which requires excellent knowledge of the labyrinthine block together with quantitative analysis of temporal bone CT. METHODS: CT-based quantitative measurements were obtained in patients undergoing vestibular neurectomy with a presigmoid approach. Eighteen patients were enrolled, and five measures were taken: Trautmann's area, the petro-clival angle, presigmoid dura length and its angle. The relationship between these measurements and hospitalization days, operating times, and complications was explored. RESULTS: The posterior semicircilar canal (PSC)-sigmoid sinus (SS) distance, presigmoid dura- internal auditory canal (IAC)-PSC angle, and duration of surgery are predictors of complications. Specifically, a PSC-sigmoid sinus distance <11 mm, a dura presig-IAC-PSC angle <14 are associated with the highest risk of complications. CONCLUSION: Preoperative temporal bone CT scan can guide the surgeon through the narrowest areas of the surgical approach. Trautmann's triangle area and petro-clival angle reduction are challenging and can be faced with combined microscopic-endoscopic technique, and with optics angulation-rotation. The retrolabyrinthine approach can enable hearing preservation and minimal cerebellar retraction.

Selective Vestibular Neurectomy through the Presigmoid Retrolabyrinthine Approach in the Treatment of Meniere's Disease.

BACKGROUND: Meniere's disease (MD) is a disabling disease, especially in patients who are refractory to medical therapy. Moreover, selective vestibular neurectomy (VN), in these selected cases, can be considered a surgical alternative which preserves hearing function and facial nerve. METHODS: We retrospectively studied 23 patients with MD diagnosis and history of failed extradural endolymphatic sac surgery (ELSS) who underwent combined micro-endoscopic selective VN, between January 2019 and August 2023, via a presigmoid retrolabyrinthine approach. All patients were stratified according to clinical features, assessing preoperative and postoperative hearing levels and quality of life. RESULTS: At the maximum present follow-up of 2 years, this procedure is characterized by a low rate of complications and about 90% vertigo control after surgery. No definitive facial palsy or hearing loss was described in this series. One patient required reintervention for a CSF fistula. Statistically significant (p = 0.001) difference was found between the preoperative and the postoperative performance in terms of physical, functional, and emotive scales assessed via the DHI questionnaire. CONCLUSIONS: Selective VN via a presigmoid retrolabyrinthine approach is a safe procedure for intractable vertigo associated with MD, when residual hearing function still exists. The use of the endoscope and intraoperative neuromonitoring guaranteed a precise result, saving the cochlear fibers and facial nerve. The approach for VN is a familiar procedure to the otolaryngologist, as is lateral skull base anatomy to the neurosurgeon; therefore, the best results are obtained with multidisciplinary teamwork.

Endolymphatic Duct and Sac Decompression: A New Life for an Old Technique.

BACKGROUND: Ménière's disease is an inner ear disorder causing recurrent vertigo, hearing loss, and tinnitus. Diagnosis is based on the variability of the symptoms over time and absence of radiological abnormalities. Medical therapy is effective only in a small percentage of patients. Surgical strategies remain controversial. In this article, we revisit a surgical technique neglected over the years: endolymphatic sac surgery. METHODS: Fifty-four patients affected by Ménière's disease underwent endolymphatic duct and sac decompression. According to the American Academy of Otolaryngology-Head and Neck Surgery criteria, vertigo control was evaluated with follow-up at 6 months, 1 year, and 2 years from the intervention. Hearing results were evaluated before the surgery and at 2 years of follow-up using the pure tone average. The results were compared with similar techniques of endolymphatic sac surgery described in the literature. RESULTS: According to the American Academy of Otolaryngology-Head and Neck Surgery criteria classification, 2 years after surgery, 87% patients achieved complete control of vertigo (class A). The hearing remained stable in 93.5% of patients. The results appear compatible with other publications data regarding endolymphatic sac surgeries. CONCLUSION: The duct and endolymphatic sac decompression allows the control of vertigo and preserves hearing from the pathological effects of Ménière's disease. The revised technique allows the functional restoration of endolymphatic homeostasis.

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.

Minimal invasive resurfacing: an innovative technique for the superior semicircular canal dehiscence. A case series.

The superior semicircular canal dehiscence is a vestibular disease recognized condition in recent years, and surgical therapy has been modeling itself over the years to ensure the control of vestibular symptoms and auditory symptoms. In this case series, the authors have experienced an intervention aimed at closing the superior semicircular canal dehiscence through the insertion of bone paté between the meninx and the residual middle cranial fossa bone wall. Seven patients underwent this intervention, they reported an improvement in all vestibular and auditory symptoms, and hearing threshold remained stable. Despite the small sample size, the difference was significant in the control of dizziness and the reduction of pulsatile tinnitus. The technique described in this article allows the control of symptoms in superior semicircular canal dehiscence, and it is a type of surgery familiar to the otosurgeon and easily replicable as it involves a modified mastoidectomy. More data are needed.

Could Music Minimize Discomfort and Pain During Office-Based ENT Surgery?

BACKGROUND: Video-assisted endoscopic radiofrequency inferior turbinate volume reduction (RFVTR) is one of the most common surgical therapies for inferior turbinate hypertrophy (ITH). Despite all the technical and surgical advancement, it is advisable to reduce as low as possible the intraoperative discomfort. The aim of this study is to evaluate the role of music in reducing patient discomfort during RFVTR. MATERIALS AND METHODS: Twenty-three patients with chronic nasal obstruction due to ITH and candidate to RFVTR are included. Before the procedure each patient filled in a completed Italian version of the state anxiety questionnaire (State-Trait Anxiety Inventory), SNOT 22 questionnaire, VAS, and chose their favourite music to be played during RFVTR. All patients evaluate the intraoperative discomfort with a visual analog scale (VAS) and for each patient, vital parameters such as blood pressure and heart rate were recorded 15 minutes before the procedure, during and after RFVTR. RESULTS: The intraoperative VAS scores during listening to music (5.7 ± 2.42 vs 6.7 ± 1.97; p< 0.05) were significantly lower, such as systolic BP (133.5 ±17.2 vs 136.78 ±16.8; p< 0.05) and heat rate (80.3 ±14.9 vs 81.7 ±15.5; p NS). During our survey, most of the patients preferred listening to classical music and none preferred rock music. No correlation was found between STAI 1-2 and intraoperative surgical discomfort evaluated both with VAS and cardiac parameters (systolic BP and HR). CONCLUSIONS: Music can be useful as a complementary method to control anxiety and reduce perception of pain in an office-based procedure, such as the RFVTR. The patient is more relaxed and experiences less discomfort; thus the surgeon and nurse can work with more confidence.

Mobile applications in otolaryngology for patients: An update.

OBJECTIVE: Recently smartphones and tablets have spread in developed countries, and healthcare-related apps are growing incredibly in different specialties. The aim of this study is to provide an up-to-date review of the current OtoHNS (otolaryngology-head and neck surgery) apps developed for patients. METHODS: This mobile applications review was conducted in September 2017. Relevant apps about OtoHNS were searched in the Apple Store and in the Google Play using various keywords. We included helpful apps for OtoHNS patients. Apps for medical students, physician (95 apps) and non-English apps (6 apps) were excluded. RESULTS: At the end of our selection process, 216 apps have been included for mobile applications review. The number of apps published per year in OtoHNS has increased each year. The most common apps were about hearing, in particular 63 of 216 (29%) were hearing test; 75 of 216 (35%) for tinnitus treatment; 10 of 216 (5%) for sounds measurement around the patients; and 7 of 216 (3%) to treat vertigo. One hundred thirty-seven of 216 (63%) apps were free of charge. Physicians were clearly involved in the app's development in only 73 of 216 (34%) apps. One hundred sixty-three of 216 (75%) had no user ratings. CONCLUSIONS: Apps are increasingly and easily accessible, although their use in clinical practice is not yet totally accepted. Our review showed that most apps have been created with no guidance from otolaryngologist. Further steps are needed to regulate apps' development. Hoping an "App Board," such as editorial board for scientific journal, to assess app quality, validity, and effectiveness before they can be fully incorporated into clinical practice and medical education. LEVEL OF EVIDENCE: N/A.

Vestibular rehabilitation in benign paroxysmal positional vertigo: Reality or fiction?

The objective of this article is to systematically review the evidence on the effectiveness of vestibular rehabilitation (VR) in patients with benign paroxysmal positional vertigo (BPPV). Relevant published studies about VR in BPPV were searched in PubMed, Google Scholar and Ovid using various keywords. We included trials that were available in the English language and did not apply publication year or publication status restrictions. Studies based on the VR in other peripheral and/or central balance disorders are excluded. Primary outcome was the effect on vertigo attacks and balance. Of 42 identified trials, only 12 trials fulfilled our inclusion criteria and were included in this review. Three of them investigated the role of VR in patients with BPPV comparing with no treatment, two of them evaluated the efficacy of VR versus medications, seven of them have highlighted the benefits of the VR alone or in combination with canalith repositioning procedure (CRP) compared to CRP alone. The studies differed in type of intervention, type of outcome and follow-up time. VR improves balance control, promoting visual stabilization with head movements, improving vestibular-visual interaction during head movement and expanding static and dynamic posture stability. CRP and VR seem to have a synergic effect in patients with BPPV, especially in elderly patients. VR does not reduce the recurrence rate, but it seems to reduce the unpleasantness. So VR can substitute CRP when spine comorbidities contraindicate CRP and can reduce the uptake of anti-vertigo drugs post CRP. Further studies are needed to confirm these encouraging results.

"Canalolabyrinthine Schwannoma," A Rare Variant of Intralabyrinthine Schwannoma: A Case Report.

Canalolabyrinthine schwannoma is a rare subtype of neuroma. Only 1 case has been described in the literature. We report the clinical case of a 51-year-old Caucasian female with Meniere's disease-like symptoms. Magnetic resonance imaging showed right VIII cranial nerve schwannoma that had different characteristics from the classical described types. The peculiar features of our case of intralabyrithine canalolabyrinthine schwannoma directed the surgeon and radiologist to tailored considerations for follow-up and therapy.

Cervical spine disorders and its association with tinnitus: The "triple" hypothesis.

Subjective tinnitus and cervical spine disorders (CSD) are among the most common complaints encountered by physicians. Although the relationship between tinnitus and CSD has attracted great interest during the past several years, the pathogenesis of tinnitus induced by CSD remains unclear. Conceivably, CSD could trigger a somatosensory pathway-induced disinhibition of dorsal cochlear nucleus (DCN) activity in the auditory pathway; furthermore, CSD can cause inner ear blood impairment induced by vertebral arteries hemodynamic alterations and trigeminal irritation. In genetically -predisposed CSD patients with reduced serotoninergic tone, signals from chronically stimulated DCNs could activate specific cortical neuronal networks and plastic neural changes resulting in tinnitus. Therefore, an early specific tailored CSD treatments and/or boosting serotoninergic activity may be required to prevent the creation of 'tinnitus memory circuits' in CSD patients.

Hyaluronic acid and upper airway inflammation in pediatric population: A systematic review.

BACKGROUND: Inflammatory disease of upper airway in pediatric population represents a social problem for both the pharmaco-economic impact and a burden for the family. To date, the use of topical therapies represents a significant therapeutic progress because they are able to reduce mucosal inflammation and improve tissue healing. Topical Hyaluronic Acid (HA) is a promising molecule that has been recently proposed as adjuvant treatment in the inflammatory disease of the upper aerodigestive tract (UADT) infections. AIMS: The aim of our work was to review the published literature regarding all the potential therapeutic effects of HA in the inflammatory disease of upper airway in pediatric population and evaluate the effectiveness of HA, alone or in combination, in children affected by cystic fibrosis. METHODS: Relevant published studies about use of HA in UADT in pediatrics were searched in Pubmed, Google Scholar, Ovid using various keywords with no limit for the year of publication. Studies based on the use of HA with nasal packing and with invasive administration of HA were excluded. RESULTS: At the end of our selection process, four publications have been included: one of them in children with recurrent upper respiratory tract infections, one of them in children with bacterial acute rhinopharyngitis, two of them in children affected by cystic fibrosis. CONCLUSIONS: Topical administration of HA plays a pivotal role in all the children suffering from UADT inflammatory disease, and positive results are generally observed in children with cystic fibrosis.

Hyaluronic acid: Perspectives in dentistry. A systematic review.

To date, topical therapies guarantee a better delivery of high concentrations of pharmacologic agents to the soft periodontal tissue, gingiva, and periodontal ligament as well as to the hard tissue such as alveolar bone and cementum. Topical hyaluronic acid (HA) has recently been recognized as an adjuvant treatment for chronic inflammatory disease in addition to its use to improve healing after dental procedures. The aim of our work was to systematically review the published literature about potential effects of HA as an adjuvant treatment for chronic inflammatory disease, in addition to its use to improve healing after common dental procedures. Relevant published studies were found in PubMed, Google Scholar, and Ovid using a combined keyword search or medical subject headings. At the end of our study selection process, 25 relevant publications were included, three of them regarding gingivitis, 13 of them relating to chronic periodontitis, seven of them relating to dental surgery, including implant and sinus lift procedures, and the remaining three articles describing oral ulcers. Not only does topical administration of HA play a pivotal key role in the postoperative care of patients undergoing dental procedures, but positive results were also generally observed in all patients with chronic inflammatory gingival and periodontal disease and in patients with oral ulcers.

A safe transoral surgical approach to parapharyngeal tumor arising from deep lobe of parotid gland.

The management of parapharyngeal tumor is surgical, but the approach remains a challenge. Attention should be paid to avoidance intra-operative bleeding or cranial nerves damage. We report a case of a 67-year-old male complaining of left-ear fullness. A submucosal mass arising from the lateral wall of oropharynx on the left side was observed. Magnetic resonance imaging detected a mass arising from the parotid gland, in particular from the deep lobe, and a fine needle biopsy was compatible with "Warthin tumor." We performed a mini-invasive transoral approach under magnification, previous isolation of homolateral vessels. The decision on which surgical approach to be used is determined by site, size vascularity, and histology of the tumor. A literature review of the main surgical approaches was performed. We performed a combined transoral dissection under magnification with cervicotomic exposure of the neck vascular bundle allowing to dissect the tumor and manage any intra-operative complications.

Hyaluronic Acid: Perspectives in Upper Aero-Digestive Tract. A Systematic Review.

BACKGROUND: To date, topical therapies guarantee a better delivery of high concentrations of pharmacologic agents to the mucosa of the upper aerodigestive tract (UADT). The use of topical drugs, which are able to reduce mucosal inflammation and to improve healing tissues, can represent a relevant therapeutic advance. Topical sodium hyaluronate (SH) has recently been recognized as adjuvant treatment in the chronic inflammatory disease of the UADT. AIMS: The aim of our work was to review the published literature regarding all the potential therapeutic effects of SH in the chronic inflammatory disease of UADT. METHODS: Relevant published studies were searched in Pubmed, Google Scholar, Ovid using keywords ("sodium hyaluronate" and "upper airways") or Medical Subject Headings. RESULTS: At the end of our selection process, sixteen publications have been included. Six of them in the post-operative period of nasal-sinus surgery, 2 of them in pediatric patients affected by recurrent upper respiratory tract infections, 4 of them in reducing symptoms and preventing exacerbations of chronic upper airways in adult population, 4 of them in patients with chronic inflammatory disease of UADT, including gastro-esophageal reflux disease (GERD). CONCLUSIONS: Topical administration of SH plays a pivotkey role in the postoperative phase of patients undergoing FESS and nasal surgery, and positive results are generally observed in all the patients suffering from UADT chronic inflammatory disease.

The potential role of hyaluronan in minimizing symptoms and preventing exacerbations of chronic rhinosinusitis.

BACKGROUND: This study was designed to prospectively evaluate the role of nebulized hyaluronic acid (HA) given for 10 days/mo over 3 months as adjunct treatment to minimize symptoms and preventing exacerbation of chronic rhinosinusitis (CRS). METHODS: Thirty-nine eligible patients were randomized to receive nebulized 9-mg sodium hyaluronate nasal washes plus saline solution (21 patients) or 5 mL of saline alone (18 patients), according to an open-label, parallel-group design, with blind observer assessment. A questionnaire about main CRS discomfort and nasal endoscopy for mucous discharge and/or mucosal edema of nasal cavities was used to assess primary outcomes of treatments. Secondary outcome measures included side effects and satisfaction. RESULTS: HA significantly improved quality of life in CRS patients according to the CRS questionnaire (16± 3.72 versus 11.52 ± 4.28; p < 0.001), contrary to saline group scores (18.92 ± 3.09 versus 18.21 ± 3.21; p = 0.55). The HA group showed significantly reduced osteomeatal edema (2.42 versus 1.52; p < 0.001) and secretions (0.95 versus 0.42; p < 0.001), whereas there was no statistically significant difference in the saline group. The compliance to the treatment was similar in both groups and no side effects were recorded. CONCLUSION: The results of this study suggested that intermittent treatment with topical 9-mg sodium hyaluronate plays a role in minimizing symptoms and could prevent exacerbations of CRS.
