Management and postoperative use of double-cannula irrigation-drainage tube in cervical necrotizing fasciitis: a Chinese single-institution experience of 46 patients.

PURPOSE: This study aimed to analyze a Chinese institution's experience with managing cervical necrotizing fasciitis (CNF) and observe the effects of a new therapeutic approach for postoperative drainage system. METHODS: A retrospective study was established including a total of 46 CNF patients who underwent surgical debridement between April 2006 and April 2018. Analyses of demographic data, etiology, comorbidity, microbiology, complications, treatment methods, duration of treatment, and treatment outcomes were obtained. RESULTS: There were 16 kinds of microbes cultured in 29 patients. Diabetic patients were more commonly infected by microbes (P < 0.05). There was a significant reduction in the number of operative time (P < 0.05) and length of hospitalization (P < 0.01) with postoperative therapy of double-cannula irrigation-drainage (DCID) system. CONCLUSION: CNF management includes controlling for comorbidities especially glycemic control and reasonable utilization of antibiotics and aggressive postoperative therapy. DCID system can effectively reduce operative frequency and duration of hospitalization.

Associated predictors of therapeutic response to uvulopharyngopalatoplasty for severe obstructive sleep apnea hypopnea syndrome.

The aim of this study was to determine the associated factors affecting the outcome of uvulopharyngopalatoplasty (UPPP) in patients with severe obstructive sleep apnea hypopnea syndrome (OSAHS), and to investigate whether cephalometric measurements were predictive of the therapeutic response to UPPP in patients with severe OSAHS. We retrospectively studied 51 consecutive patients who underwent revised UPPP with uvula preservation (H-UPPP), or Z-palatopharyngoplasty (ZPPP) for severe OSAHS [apnea-hypopnea index (AHI) >30]. All patients were evaluated using physical examination, Epworth Sleepiness Scale (ESS), cephalometry, and nocturnal polysomnography (PSG) before surgery and at 6-12 months after surgery. Based on the success criteria defined as an AHI of <20 and a decrease >50 %, the overall success rate was 45.1 %. The preoperative distance from the posterior border of the uvula to the middle pharyngeal wall (U-MPW) was significantly longer in the responder group than in the nonresponder group, when considering the whole group or the H-UPPP group alone. Among all study subjects, U-MPW and change in body mass index (△BMI) were the significant predictors of surgical success. U-MPW was the key predictor for H-UPPP surgical success, whereas mandibular plane angle (MPA) and Friedman stage were the key predictors for ZPPP surgical success. In conclusion, U-MPW was a significant predictor of UPPP surgical success. Patients with U-MPW >10 mm who are unwilling to receive nasal continuous positive airway pressure (CPAP) therapy might be suitable candidates for UPPP surgery.

Primary maxillomandibular advancement with concomitant revised uvulopalatopharyngoplasty with uvula preservation for severe obstructive sleep apnea-hypopnea syndrome.

BACKGROUND: This study aimed to evaluate the efficacy and safety of primary maxillomandibular advancement (MMA) with concomitant adjunctive revised uvulopalatopharyngoplasty with uvula preservation (H-UPPP) in selected patients with severe obstructive sleep apnea-hypopnea syndrome (OSASH). METHODS: Eleven consecutive male patients with velo-orohypopharyngeal and hypopharyngeal narrowing underwent MMA with concomitant H-UPPP for severe OSAHS. All patients underwent a physical examination, Epworth Sleepiness Scale evaluation, cephalometry, nocturnal polysomnogram, and velopharyngeal insufficiency questionnaire survey before and at 6 to 12 months after surgery. RESULTS: On the basis of the success criteria, defined as an apnea-hypopnea index less than 20 and a decrease greater than 50%, the success rate was 91%. The apnea-hypopnea index decreased from 67.44 (13.30) to 9.41 (7.20) events per hour (P < 0.001) and the lowest oxygen saturation increased from 63.0% (10.70%) to 88.55% (4.59%) (P < 0.001) after surgery. All patients showed a significant decrease in mandibular plane to hyoid bone and increase in PAS after surgery. One patient reported regurgitation of liquids when drinking hastily after surgery. Two patients reported regurgitation as occasional occurrences. Half a year later, 2 patients reported complete resolution of the symptoms. One patient still complained of rare regurgitation of liquids when drinking quickly. Five patients had paresthesia of the lower lip; in 4 patients, the paresthesia had resolved by 12 months after surgery. One patient still complained of paresthesia of the lower lip after 2 years of follow-up. No major complication (eg, upper airway obstruction) occurred. CONCLUSIONS: Primary MMA with concomitant adjunctive H-UPPP is effective in selected patients with severe OSAHS without major complications.
