BACKGROUND:To the authors' knowledge, the question of whether human papillomavirus (HPV) infection is associated with outcomes in patients with sinonasal squamous cell carcinoma (SNSCC) is not well studied at this time. In the current study, the authors investigated patterns of HPV testing and its association with survival in patients with SNSCC using the National Cancer Data Base. METHODS:The authors selected all SNSCC cases diagnosed between 2010 and 2016. HPV testing practices, clinicodemographic factors, treatments, and survival were analyzed. Multivariable Cox regression and propensity score-matched survival analyses were performed. RESULTS:A total of 6458 SNSCC cases were identified. Of these, only 1523 cases (23.6%) were tested for HPV and included in the current study. The median patient age was 64 years and the majority had advanced stage tumors (overall AJCC stage III-IV, 721 patients; 62.1%). HPV-positive SNSCC comprised 31.5% (447 of 1418 cases) of the final study cohort. Among 15 hospitals that routinely tested nonoropharyngeal SCCs for HPV, the percentage of HPV-positive SNSCCs was smaller (24.6%; P = .04). Patients with HPV-positive SNSCC were younger (aged 60 years vs 65 years; P < .001), with tumors that were more likely to be high grade (55.3% vs 41.7%; P < .001), and attributed to the nasal cavity (62.2% vs 44.0%; P < .001). HPV-positive SNSCC was associated with significantly improved overall survival in multivariable regression analysis (hazard ratio, 0.45; 95% CI, 0.28-0.72 [P = .001]) and propensity score-matched (hazard ratio, 0.61; 95% CI, 0.38-0.96 [P = .03]) analyses controlling for clinicodemographic and treatment factors. CONCLUSIONS:Currently, only a minority of patients with SNSCC are tested for HPV. However, a sizable percentage of SNSCC cases may be HPV related; furthermore, HPV-positive SNSCC is associated with improved overall survival. Routine HPV testing may be warranted in patients with SNSCC.

OBJECTIVES:To assess the independent relationships of obesity and obstructive sleep apnea (OSA) with hypertension/elevated blood pressure (EBP) in adolescent patients. STUDY DESIGN:A retrospective cohort analysis was performed on 501 patients (age 13-21 years) with three separate blood pressure measurements within 6 months of polysomnography. EBP was defined as average systolic blood pressure (SBP) ≤120 mm Hg; obesity as body mass index Z-score ≤1.65; and OSA as obstructive apnea-hypopnea index <1. Pearson correlations and multivariable analyses were performed to assess the independent effects of the apnea-hypopnea index and body mass index Z-score on SBP. RESULTS:Of 501 patients (mean age 16 ± 2 years), 246 (49%) were male. OSA was present in 329 (66%) patients, obesity in 337 (67%), and EBP in 262 (52%). EBP was present in 70% of obese adolescents and 60% of adolescents with OSA. Univariable correlation showed a significant relationship between SBP, body mass index Z-score, and apnea-hypopnea index. Multivariable linear regression analysis showed blood pressure was significantly associated with body mass index Z-score (β = .46; P < .01), age (β = .25; P < .01), and height Z-score (β = .14; P < .01), but not apnea-hypopnea index (β = .01; P = .72). CONCLUSIONS:The relationship between OSA and EBP in adolescents is most closely associated with the degree of obesity. Further studies are needed to assess the effect of the treatment of obesity and OSA on blood pressure in adolescents.

Background/UNASSIGNED:Upper Airway Stimulation (UAS) is a well-established therapy option for obstructive sleep apnea (OSA). Aims/UNASSIGNED:There are no data on whether respiratory sensing contributes to successful UAS therapy. Materials & Methods/UNASSIGNED:After initial measurements of 3 implanted patients (M1), the sensing signal was inverted (M2) without changing other parameters. Two weeks later, the signal was converted back again, and the sensitivity of breathing cycle detection was turned to a very low state (M3). Results/UNASSIGNED:At M2 and M3, the apnea-hypopnea index and oxygen desaturation index increased. Discussion/UNASSIGNED:Correct respiratory sensing is important for controlling OSA using UAS. Conclusions/UNASSIGNED:Therefore, implant centers should should optimize respiratory sensing placement and adjustment.

OBJECTIVES/HYPOTHESIS/OBJECTIVE:Description of a novel use of a submandibular gland (SMG) flap pedicled on the facial vessels to restore facial volume after parotidectomy, and comparison of clinical outcomes with alternative modes of reconstruction. STUDY DESIGN/METHODS:Retrospective chart review. METHODS:The surgical technique for a SMG flap is described. Retrospective chart review of cases of parotidectomy at a single tertiary medical center was conducted (n = 43). Cases were grouped in three cohorts of consecutive patients depending on reconstruction technique: SMG flap (n = 13), sternocleidomastoid muscle (SCM) flap (n = 15), and no flap (n = 15). Cohort characteristics and complication rates are reported. RESULTS:The SMG flap was more often used for a malignant pathology (92%) and in conjunction with a neck dissection (100%), compared to the SCM flap (47% and 15%) or no flap (0% and 0%), respectively. The mean House-Brackmann score in the immediate postoperative period in the SMG-flap group was slightly elevated compared to the other groups: 1.6 (standard deviation [SD] ± 0.5) versus 1.1 (SD ± 0.3) and 1.0 (SD ± 0.0). Otherwise, the complication rate was similar across groups. CONCLUSIONS:The SMG flap is a safe and effective option for volume restoration after parotidectomy. It provides durable volume that will not atrophy and is already exposed in the field of dissection for patients undergoing concurrent level I neck dissection. LEVEL OF EVIDENCE/METHODS:3.

OBJECTIVE:We describe our experience using the extracorporeal video microscope, the "exoscope" for repair of a temporal bone encephalocele. METHOD/METHODS:The patient is a 69-year-old male with a right temporal lobe encephalocele herniating through a tegmen defect. He underwent definitive tegmen defect repair and bipolar cauterization of the encephalocele. The authors elected for a combined transmastoid and transtemporal approach in order to isolate the tegmen defect and provide watertight repair. The Synaptive robotic BrightMatter (Toronto, ON) drive video exoscope monitor system was used for the entirety of the case including both the transmastoid approach and transtemporal craniotomy. RESULTS:No intraoperative complications were encountered during either the transmastoid (mastoidectomy) or transtemporal craniotomy. The authors were able to complete the entire case without abandonment of the exoscope in favor of the traditional binocular microscope. Advantages of this technology in clinical practice includes high-resolution three-dimensional visualization, increased degrees of freedom for exoscope adjustment, and reduced surgeon fatigue in a fixed, unnatural posture. Limitations include decreased depth perception and increased operative time. CONCLUSION/CONCLUSIONS:The exoscope system is a safe and effective alternative or adjunct to the existing binocular operating microscope for lateral skull based procedures. The exoscope provides the surgeon with a comfortable, high-resolution visualization without compromising surgical exposure and patient safety.SDC video link: http://links.lww.com/MAO/A837.

OBJECTIVE:Cochlear implant (CI) technology and techniques have advanced over the years. There has not been the same degree of change in programming and there remains a lack of standardization techniques. The purpose of this study is to compare performance in cochlear implant subjects using experienced clinician (EC) standard programming methods versus an Artificial Intelligence, FOX based algorithm for programming. STUDY DESIGN/METHODS:Prospective, nonrandomized, multicenter study using within-subject experimental design SETTING:: Tertiary referral centers. PATIENTS/METHODS:Fifty-five adult patients with ≥ 3 months experience with a Nucleus 5, 6, Kanso, or 7 series sound processor. INTERVENTION/METHODS:Therapeutic Main Outcome Measures: CNC words and AzBio sentences in noise (+10 dB SNR) tests were administered in a soundproof booth followed by a direct connect psychoacoustic battery using the EC program. Tests were repeated 1 month later using the optimized FOX program. Subjective measures of patient satisfaction were also measured. RESULTS:Performance for the EC program was compared to the FOX program for both measures. Group mean results revealed equivalent performance (Kruskal-Wallis ANOVA p = 0.934) with both programming methods. While some patients had better performance with the FOX method and some performed more poorly, the majority had equivalent performance and preferred the FOX system. CONCLUSION/CONCLUSIONS:The study demonstrated that on average, FOX outcomes are equivalent to those using traditional programming techniques. In addition, the FOX programming method can effect standardization across centers and increase access for many individuals who could benefit.

Nasal septal perforations can cause issues of epistaxis, whistling, crusting, saddle deformity, and obstruction, which motivate patients to seek surgical repair. Numerous methods of septal perforation repair have been described, with surgical success rates ranging from 52% to 100%, but few studies address situations with concomitant septal deviation. In treating patients with septal perforation and deviation, both issues should be addressed for optimal outcomes. While routine septoplasty involves the removal of septal cartilage, septal perforation repair involves the addition of interposition grafts. The composite chondromucosal septal rotation flap harmoniously combines these seemingly conflicting goals as an effective and efficient technique for septal perforation repair. We present 3 patients successfully treated for their septal perforation and septal deviation concurrently with this technique.

OBJECTIVE:To identify risk factors and interventions affecting length of hospitalization (LOH) and clinical outcome in children with intracranial complications of rhinosinusitis. METHODS:Retrospective chart review of 12 children hospitalized at 2 academic medical centers for intracranial complications of rhinosinusitis over the past 5 years. RESULTS:12 patients were identified with an average age at presentation of 13 years old. 92% were male and 75% were African American. The most common presenting symptoms were fever and headache. Localizing neurological symptoms including hemiparesis and aphasia, in addition to seizures occurred in 33% of patients and increased LOH significantly (33 versus 15 days, p = 0.03). Epidural (EA) and subdural abscesses (SA) were the most common intracranial complications. 58% of patients were initially treated with a combination of open neurosurgical (ON) intervention and endoscopic sinus surgery (ESS) and LOH was significantly shorter for these patients compared to those treated otherwise (14 versus 31 days, p = 0.02). Streptococcus species were the most common group of bacteria identified in 75% of cases, with S. anginosus accounting for 42% of cases. The overall average LOH was 21 days with 92% of patients having complete resolution of symptoms by time of discharge. CONCLUSIONS:Treatment of intracranial complications of acute rhinosinusitis can have favorable outcomes after appropriate surgical management. Localizing neurologic symptoms and seizures portend longer hospital stay and recovery time. Shorter hospital stay was seen in those undergoing early combined ON and ESS interventions.
