Treatment of primary epiglottis collapse in OSA in adults with glossoepiglottopexy: a 5-year experience.

Objective: To review our 5-year experience with a modified version of glossoepiglottopexy for treatment of obstructive sleep apnoea syndrome (OSA) in two hospitals. Methods: A retrospective analysis was carried out on a cohort of adult patients affected by OSA suffering from primary collapse of the epiglottis who underwent a modified glossoepiglottopexy. All patients underwent drug-induced sleep endoscopy, polysomnographic and swallowing evaluation, and assessment with the Epworth Sleepiness Scale (ESS). Results: Forty-nine patients were retrospectively evaluated. Both the apnoea-hypopnoea index (AHI) (median AHIpost-AHIpre = -22.4 events/h; p < 0.001) and oxygen desaturation index (ODI) showed a significant postoperative decrease (median ODIpost-ODIpre = -18 events/h; p < 0.001), as did hypoxaemia index (median T90% post-T90% pre = -5%; p < 0.001). The ESS questionnaire revealed a significant decrease in postoperative scores (median ESSpost-ESSpre =- 9; p < 0.001). None of the patients developed postoperative dysphagia. Conclusions: Our 5-year experience demonstrates that modified glossoepiglottopexy is a safe and reliable surgical technique for treatment of primary epiglottic collapse in OSA patients.

Conventional approaches versus laser CO2 surgery in stapes surgery: a multicentre retrospective study.

PURPOSE: To analyze and compare surgical and audiological outcomes of conventional approaches versus laser CO2 surgery in stapes surgery. METHODS: 333 patients who underwent stapes surgery were enrolled in the study; the patient population was divided into three groups: group 1: 170 patients treated with conventional stapedotomy with manual microdrill (average age 49.13 years); group 2: 119 patients treated with conventional stapedotomy with electrical microdrill (average age 51.06 years); group 3: 44 patients (average age 50.4 years) who underwent CO2 laser stapedotomy. Intra-operative, postoperative outcomes and audiological results were investigated. RESULTS: The average surgical time of laser CO2 surgery was longer than for other surgical procedures. No statistical differences emerged in post-operative abnormal taste sensation. There was also no difference in postoperative dizziness. Air-bone gap (ABG) went down from 29.7 ± 10 dB (group 1) and 27.32 ± 9.20 (group 2) to 10 ± 6.9 dB (group 1) and 10.7 ± 6.03 dB (group 2). In group 3 the preoperative ABG was lowered from 28.3 ± 10.1 to 11.8 ± 10.9, with a statistical difference in auditory recovery (p = 0.0001); The group of patients treated with laser CO2 showed a percentage of patients with an ABG closure of between 0 and 10 dB higher than in the group treated with manual microdrills (77.2% vs. 60%, respectively; p = 0.03). CONCLUSION: Overall surgical results of CO2 laser and conventional stapedotomy are comparable without any significant difference; however, the group treated with CO2 laser appears to have a percentage of patients with an ABG closure 0-10 dB higher than the group treated using the conventional technique.

Outcome predictors for non-resective pharyngoplasty alone or as a part of multilevel surgery, in obstructive sleep apnea-hypopnea syndrome.

PURPOSE: Non-resective pharyngoplasty techniques have been shown to be effective to treat oropharyngeal collapse in patients affected by obstructive sleep apnea-hypopnea syndrome (OSAHS). The aim of our study is to evaluate outcome predictors in a cohort of patients affected by OSAHS and treated with non-resective pharyngoplasty, including variation of pharyngeal measures at the end of the surgical procedure. METHODS: A cohort of patients affected by OSAHS, with palatal or lateral pharyngeal wall collapse, who underwent non-resective pharyngoplasty, were enrolled between 2014 and 2017. Surgical procedures encompassed non-resective pharyngoplasty by expansion sphincter pharyngoplasty (ESP) or barbed antero-lateral pharyngoplasty with barbed reposition pharyngoplasty (BRP) or barbed suspension pharyngoplasty (BSP) techniques, eventually associated with nasal surgery. Pharyngeal measures were recorded intraoperatively and their variation at the end of the procedure was considered. Surgical success was evaluated at least 6 months after surgery with respiratory polygraphy and ESS questionnaire. Outcome predictors were examined by multivariable logistic regression and ROC curve analysis. RESULTS: Seventy patients met the study inclusion criteria. ESP, BRP, and BSP in a uni-/multilevel setting led to significant improvement of all respiratory polygraphic parameters and daily sleepiness (p < 0.0001). Outcome analysis showed that greater variation of antero-posterior pharyngeal measure was associated with success (p = 0.01), with an optimal cutoff value of 8.5 mm; low AHIpre, high ESSpre, and antero-lateral pharyngoplasty with barbed sutures were associated with a higher rate of cure (p < 0.05). CONCLUSIONS: Non-resective pharyngoplasty is effective in treating OSAHS patients affected by palatal or lateral pharyngeal wall collapse, and intraoperative variation of antero-posterior width may be a useful tool to predict surgical success.

Barbed suspension pharyngoplasty for treatment of lateral pharyngeal wall and palatal collapse in patients affected by OSAHS.

PURPOSE: The aim of this study is to analyze the efficacy of a new modified pharyngoplasty technique with barbed sutures: barbed suspension pharyngoplasty (BSP). METHODS: We enrolled patients affected by obstructive sleep apnea-hypopnea syndrome (OSAHS), having the main site of obstruction at the palatal and lateral pharyngeal walls, who refused or failed to tolerate CPAP therapy and underwent non-resective pharyngoplasty with barbed sutures between January 2014 and October 2017. Two surgical techniques with barbed sutures were used: barbed reposition pharyngoplasty (BRP) and BSP; the main characteristics of the latter are a double passage of the needle, each side, through the soft palate. RESULTS: Forty-two patients met the study inclusion criteria and were included in the analysis. Twenty-two patients underwent BRP and 20 BSP. Patients treated with both BRP and BSP achieved significant improvement in polysomnographic parameters: AHI, ODI, t90%, and daily sleepiness tested by the ESS questionnaire (p < 0.001). There were no significant differences between groups considering gender, age, or severity of OSAHS (p > 0.05). Outcomes were also comparable (p = 0.10) in the two groups; patients who underwent BSP had successful treatment in 100% of cases, compared to 86% with BRP, with a cure rate of 40% vs. 18%. CONCLUSIONS: BSP is a novel surgical technique that is effective in treating oropharyngeal collapse and can be tailored for patients with high collapsibility of the soft palate who might benefit from the palatal stiffness given by multiple passages of the suture inside it.

Subtotal petrosectomy: Surgical technique, indications, outcomes, and comprehensive review of literature.

OBJECTIVES/HYPOTHESIS: To describe the technique of subtotal petrosectomy (STP), to analyze the outcomes, and to review the literature STUDY DESIGN: A retrospective review. METHODS: Four hundred sixty cases of STP performed for various indications were included in the study, which was conducted at a quaternary referral center for otology and skull base surgery. Surgical and audiological parameters, and complications were evaluated. Our results were compared with the existing literature on the subject. RESULTS: Two hundred ninety-seven (64.6%) patients had been subjected to multiple surgeries before an STP was performed. The most common indication for STP was recurrent chronic otitis with or without cholesteatoma, with 165 (35.9%) patients. Difficult cases of cochlear implantation, temporal bone fractures, and class B3 tympanomastoid paragangliomas were the next most common indications, with 91 (19.8%), 43 (9.4%), and 38 (8.3%) cases, respectively. The median follow-up of the patient pool was 36 ± 19 months. Recidivism and postauricular wound fistula were the most common complications, seen in five (1.1%) patients each. This series of STP is the largest reported in the literature CONCLUSIONS: STP is a very useful and safe surgical tool in the management of a variety of problematic situations in otology, as it offers the possibility of a definitive cure by offering radical clearance. This procedure can be combined safely with hearing implantation procedures. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:2833-2842, 2017.

Sleep complaints and sleep breathing disorders in upper and lower obstructive lung diseases.

Upper and lower obstructive lung diseases can induce sleep complaints and can be part of the pathogenesis of sleep breathing disorders. In fact, the physiological changes of the pattern of respiration during sleep, added to the airways disease can lead to symptomatic worsening of rhinitis, asthma and chronic obstructive pulmonary diseases (COPD); moreover, their functional and anatomical features can lead to sleep breathing disorders such as obstructive sleep apnea syndrome (OSAS). This review highlights the above-mentioned relationships and the effect of disease management on its comorbidities and the patient's quality of life. Rhinitis, asthma and COPD represent causes of sleep complaints that may be reduced with optimal management of these obstructive airways diseases. Continuous positive airway pressure (CPAP) treatment of sleep apnea needs to be tailored after optimization of the therapy of concomitant diseases, but it can often ameliorate comorbid disease.
