Abstract. Pediatric sinonasal rhabdomyosarcoma (PSR) is a rare condition, with a limited number of previously reported cases. It is an aggressive malignancy associated with poor outcomes, and no consensus has been reached on the optimal therapeutic strategy. The present study reported the case of embryonal PSR in a 2-year old girl, presenting with unilateral nasal obstruction and a polypoid mass protruding from the left nasal cavity. The pediatric patient was initially treated with surgical resection, followed by adjuvant chemotherapy containing vincristine (1.5 mg/m 2 , weekly) and actinomycin-D (1.5 mg/m 2 , three times weekly). On the 10th month of follow-up, tumor recurrence was detected and a salvage surgery was performed, while the same chemotherapy regimen was resumed. Following the first cycle of chemotherapy, the patient developed a fungal bronchopneumonia and succumbed due to disease progression, acute respiratory distress syndrome and septic shock 12 months after diagnosis.
The aim of this study was to evaluate the effects of modified tongue base suspension (mTBS) procedure on continuous positive airway pressure (CPAP) levels in patients with severe obstructive sleep apnea (OSA). From November 2011 to December 2012, a total of 31 patients with severe OSA who underwent mTBS were included into this prospective case series with planned data collection. Prior to surgery, all the patients were subjected to a polysomnography (PSG) and CPAP titration on two separate nights. Following the surgery, patients were subjected to a control PSG and CPAP titration at the sixth month of follow-up period. The preoperative and postoperative mean apnea hypopnea index (AHI), CPAP titration values, AHI during CPAP use and amount of sleeping time with CPAP were compared. Median age was 48 years (range 31-66), and most patients were male (87.0 %). Postoperative mean AHI (44.73 ± 17.05 vs. 19.96 ± 19.52), optimal CPAP value (12.64 ± 1.60 vs. 8.00 ± 1.77) and AHI during CPAP use (3.79 ± 1.78 vs. 2.25 ± 1.81) were decreased, and the amount of sleeping time with CPAP (5.29 ± 0.84 vs. 6.52 ± 0.89) was increased significantly (p < 0.001 for all parameters). The surgery was considered to be successful when 50 % reduction in the mean AHI and/or the decrease of AHI below 20/h were obtained. A total of 24 patients (77.4 %) met the surgical success criteria. The mTBS is a safe and feasible procedure with favorable effects on CPAP levels in patients with severe OSA.
We aimed to evaluate existing research into the effectiveness and safety of two tongue base suspension (TBS) techniques (Repose(®) system and modified TBS) with or without uvulopalatopharyngoplasty (UPPP) in obstructive sleep apnea. The literature review was performed using PubMed database. Searched terms used included the keywords "sleep apnea", "surgery", "tongue", "tongue base", "suspension", "Repose", "uvulopalatopharyngoplasty", and "hypopharynx". Levels of evidences and grades of recommendations were determined according to the hierarchy proposed by Oxford Centre for Evidence-based Medicine. Seven studies including 113 patients met the eligibility criteria for TBS as a stand-alone procedure. Four of seven studies including 62 patients used the Repose(®), and three studies including 51 patients used the modified TBS. The success rates were higher in the studies that used modified technique (74.5 %) than those that used the Repose(®) (25.8 %), (p < 0.001). Ten studies including 300 patients met the eligibility criteria for TBS combined with UPPP. Seven of ten studies including 176 patients used the Repose(®), and three studies including 124 patients used the modified TBS. The success rates in this group were similar between the modified TBS (73.4 %) and Repose(®) (67.6 %), (p = 0.341). When aggregate data of 413 patients were compared, the modified TBS was found to be associated with significantly higher success rates (73.7 vs. 56.7 %, p < 0.001). The evidence supports primarily grade C recommendations for the benefits of both techniques with or without UPPP; although there is a trend toward improved outcome with modified technique.
The aim of this study was to evaluate the influence of multilevel upper airway surgery on subsequent continuous positive airway pressure (CPAP) use and tolerance in patients with moderate to severe obstructive sleep apnea (OSA). The study cohort enrolled 67 consecutive patients, who underwent septoplasty plus modified uvulopharyngopalatoplasty (mUPPP) with or without modified tongue base suspension (mTBS) due to CPAP intolerance, and who had residual OSA requiring CPAP therapy [non-responders to surgery, apnea-hypopnea index (AHI) >15 events/h] that had been confirmed by control polysomnography at the sixth month postoperatively. A questionnaire including questions on postoperative CPAP use, problems faced during CPAP use after the surgery, change in OSA symptoms, and satisfaction with the surgery was designed, and filled through interviews. Seventeen (25.4 %) patients had septoplasty plus mUPPP and 50 (74.6 %) had septoplasty plus mUPPP combined with mTBS. Postoperatively, mean AHI (45.00 ± 19.76 vs. 36.60 ± 18.34), Epworth sleepiness scale (ESS) score (18.00 ± 4.45 vs. 13.00 ± 4.72), oxygen desaturation index (ODI) (48.98 ± 16.73 vs. 37.81 ± 17.03), and optimal CPAP level (11.80 ± 1.40 vs. 8.96 ± 1.20) were decreased (p < 0.001 for all parameters). Fifty-nine percent of patients reported that they fairly satisfied with the surgery and 49.2 % reported that their symptoms were completely resolved. While none of the cases could tolerate CPAP before surgery, almost half (47.8 %) of the cases used CPAP without problems postoperatively. Postoperative CPAP users had significantly higher postoperative AHI (p = 0.001), supine AHI (p = 0.009), ESS (p = 0.019), and ODI (p = 0.014), and significantly lower postoperative minimum O2 saturation (p = 0.001) compared with non-users. Multilevel upper airway surgery with less invasive techniques may improve CPAP tolerance in well-selected patients.
Objectives/HypothesisOur primary objective was to evaluate the feasibility, morbidity, and efficacy of transoral robotic surgery (TORS) tongue‐base resection (TBR) combined with tongue‐base suspension (TBS) for obstructive sleep apnea (OSA) with tongue‐base collapse. Our secondary objective included evaluation of factors influencing treatment success.Study DesignSingle‐arm, prospective, observational cohort study.MethodsPatients were eligible if they had moderate‐to‐severe OSA (apnea hypopnea index [AHI] > 15) or positional OSA, had a tongue‐base collapse and glossoptosis identified by drug‐induced sleep endoscopy (DISE), and failed continuous positive airway pressure. All patients underwent TORS‐TBR combined with TBS. Additionally, concomitant epiglottoplasty, uvulopalatopharyngoplasty, or expansion pharyngoplasty were performed based on DISE findings.ResultsIn total, 64 patients were enrolled in the trial. The mean age was 45.9 years, mean body mass index was 30.5 kg/m2, and mean AHI was 41.7 events/hour. The mean robotic surgical time, total volume of tongue‐base tissue removed, and the length of hospital stay were 21.4 minutes, 15.16 mL, and 6.5 days, respectively. Postoperatively, almost all polysomnographic metrics improved significantly (AHI = 41.72 vs. 18.82 events/hour, lowest oxygen saturation = 80.43% vs. 85.14%, Epworth Sleepiness Scale = 10.49 vs. 4.09). The procedure provided an overall success rate of 75%, with minor morbidity. All patients experienced varying degrees of temporary lingual edema postoperatively. Tracheotomy was not required for any patient. Although no independent predictor of treatment success was determined, patients with more severe disease tend to exhibit lower response to the treatment.ConclusionsTORS‐TBR combined with TBS is a feasible, safe, and efficient procedure for OSA with tongue‐base collapse.Level of Evidence4 Laryngoscope, 130:2285–2291, 2020
