RESUMEN

In facial reconstruction after skin cancer resection, management and optimization of postoperative scar is a complex paradigm. Every scar is unique and presents a different challenge-whether due to anatomic, aesthetic, or patient-specific factors. This necessitates a comprehensive evaluation and an understanding of the tools at hand to improve its appearance. How a scar looks is meaningful to patients, and the facial plastic and reconstructive surgeon is tasked with its optimization. Clear documentation of a scar is critical to assess and determine optimal care. Scar scales such as the Vancouver Scar Scale, the Manchester Scar Scale, the Patient and Observer Assessment Scale, the Scar Cosmesis Assessment and Rating "SCAR" Scale, and FACE-Q, among others, are reviewed here in the context of evaluating postoperative or traumatic scar. Measurement tools objectively describe a scar and may also incorporate the patient's assessment of their own scar. In addition to physical exam, these scales quantify scars that are symptomatic or visually unpleasant and would be best served by adjuvant treatment. The current literature regarding the role of postoperative laser treatment is also reviewed. While lasers are an excellent tool to assist in blending of scar and decreasing pigmentation, studies have failed to evaluate laser in a consistent, standardized way that allows for quantifiable and predictable improvement. Regardless, patients may derive benefit from laser treatment given the finding of subjective improvement in their own perception of scar, even when there is not a significant change to the clinician's eye. This article also discusses recent eye fixation studies which demonstrate the importance of careful repair of large and central defects of the face, and that patients value the quality of the reconstruction.

RESUMEN

BACKGROUND: Case-control studies from the early 2000s demonstrated that human papillomavirus-related oropharyngeal cancer (HPV-OPC) is a distinct entity associated with number of oral sex partners. Using contemporary data, we investigated novel risk factors (sexual debut behaviors, exposure intensity, and relationship dynamics) and serological markers on odds of HPV-OPC. METHODS: HPV-OPC patients and frequency-matched controls were enrolled in a multicenter study from 2013 to 2018. Participants completed a behavioral survey. Characteristics were compared using a chi-square test for categorical variables and a t test for continuous variables. Adjusted odds ratios (aOR) were calculated using logistic regression. RESULTS: A total of 163 HPV-OPC patients and 345 controls were included. Lifetime number of oral sex partners was associated with significantly increased odds of HPV-OPC (>10 partners: odds ratio [OR], 4.3 [95% CI, 2.8-6.7]). After adjustment for number of oral sex partners and smoking, younger age at first oral sex (<18 vs >20 years: aOR, 1.8 [95% CI, 1.1-3.2]) and oral sex intensity (>5 sex-years: aOR, 2.8 [95% CI, 1.1-7.5]) remained associated with significantly increased odds of HPV-OPC. Type of sexual partner such as older partners when a case was younger (OR, 1.7 [95% CI, 1.1-2.6]) or having a partner who had extramarital sex (OR, 1.6 [95% CI, 1.1-2.4]) was associated with HPV-OPC. Seropositivity for antibodies to HPV16 E6 (OR, 286 [95% CI, 122-670]) and any HPV16 E protein (E1, E2, E6, E7; OR, 163 [95% CI, 70-378]) was associated with increased odds of HPV-OPC. CONCLUSION: Number of oral sex partners remains a strong risk factor for HPV-OPC; however, timing and intensity of oral sex are novel independent risk factors. These behaviors suggest additional nuances of how and why some individuals develop HPV-OPC.

RESUMEN

BACKGROUND: Recursive partitioning analysis (RPA) from the Radiation Therapy Oncology Group (RTOG)-0129 has identified a low-risk group of patients with oropharynx cancer (OPC) who might benefit from therapeutic de-intensification. These risk groups have not yet been reproduced in an independent cohort treated heterogeneously. Therefore, the objective of this analysis was to validate the RPA risk groups and examine the prognostic impact of novel factors. METHODS: Patients with OPC were enrolled in a prospective study at 3 academic medical centers from 2013 to 2018. Medical record abstraction was used to ascertain clinical variables including staging and survival according to the 7th edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual. Human papillomavirus-positive tumor status was determined by p16 immunohistochemistry and/or HPV RNA in situ hybridization. Kaplan-Meier and log-rank methods were used to compare survival. Cox proportional hazards were used to generate univariate and multivariable hazard ratios (HRs). RESULTS: Median follow-up time was 3.2 years. The low-, intermediate-, and high-risk groups had significant differences in 2-year overall survival (OS, 99.1%; 95% CI, 94.4%-99.9% vs OS, 93.0%; 95% CI, 74.7%-98.2% vs OS, 80.0%; 95% CI, 40.9%-94.6%; Poverall = .0001) and 2-year progression-free survival (PFS, 97.5%; 95% CI, 92.4%-99.2% vs PFS, 89.3%; 95% CI, 70.3%-96.4% vs PFS, 80.0%; 95% CI, 40.9%-94.6%; Poverall < .002). After adjustment for age, sex, and level of educational attainment, OS and PFS were significantly lower for the intermediate- (OS adjusted hazard ratio [aHR], 5.0; 95% CI, 1.0-23.0; PFS aHR, 3.4; 95% CI, 1.0-11.5), and high- (OS aHR, 7.3; 95% CI, 1.4-39; PFS aHR, 5.0; 95% CI, 1.2-21.6) risk groups compared with the low-risk group. Lower education was also independently significantly associated with worse OS (aHR, 8.9; 95% CI, 1.8-44.3) and PFS (aHR, 3.1; 95% CI, 1.0-9.6). CONCLUSIONS: In patients with OPC, the RTOG-0129 RPA model is associated with OS and PFS in a heterogeneously treated cohort.

RESUMEN

In this review, the paramedian forehead flap indications and uses are reviewed, specifically examining clinical situations where patient selection is important. In these settings, a preoperative discussion with a patient regarding surgical expectations and goals in the setting of their defect is paramount. The authors review the literature regarding the psychosocial aspects of major nasal reconstruction and review preoperative discussion points that are key to a well-informed patient and improved patient satisfaction through the nasal reconstructive process.

RESUMEN

Background: Autologous costal cartilage (ACC) and irradiated homologous costal cartilage (IHCC) are commonly used in septorhinoplasty when there is insufficient septal cartilage for grafting. Objective: To assess the surgical outcomes of patients who underwent septorhinoplasty with either ACC or IHCC as measured by rates of infection, resorption, warping, and revision rate. Methods: A retrospective analysis of patients who underwent rhinoplasty with ACC or IHCC at a single academic institution was performed. Demographic data, surgical details, antibiotic use, and outcomes, including surgical duration, infection, resorption, warping, and revision rate, were analyzed using Fisher's exact test, chi-squared test, and logistic regression. Results: One hundred forty-three patients were identified. The median age was 48 years (interquartile range: 35-57.5) and 62.2% (n = 89) were female, 61 patients (42.7%) underwent ACC, and 82 (57.3%) IHCC. Revision rate in both groups was similar (ACC = 14.8%, IHCC = 14.6%; p = 0.98). There was no difference in infection rate (ACC = 4.9%, IHCC = 3.7%; p = 0.71). Postoperative deformity and nasal obstruction were the most common indications for revision surgery. Surgical time was shorter with IHCC (p < 0.01). Mean follow-up time was 26.5 months (±25) for ACC, and 16 months (±12) for IHCC. Conclusions: ACC and IHCC are similar in terms of effectiveness and safety in septorhinoplasty.

RESUMEN

BACKGROUND: A subset of patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (HPV-OSCC) experience poor clinical outcomes. The authors of this report explored prognostic risk factors for overall survival (OS) and recurrence-free survival (RFS). METHODS: Patients with incident HPV-OSCC who received treatment at the Johns Hopkins Hospital between 1997 and 2008 and who had tissue available for HPV testing as well as demographic and clinicopathologic information (N = 176) were included. Tissue was tested for HPV by in situ hybridization (ISH) and/or p16 immunohistochemistry. Demographic and clinicopathologic information was extracted from medical records. RESULTS: In total, 157 of 176 patients (90%) with OSCC had HPV-associated disease (HPV-OSCC). In the patients with HPV-OSCC, the 3-year and 5-year OS rates were 93% (95% confidence interval [CI], 88%-98%) and 89% (95% CI, 81%-97%), respectively. Shorter survival was observed among older patients (hazard ratio [HR], 2.33 per 10-year increase; 95% CI, 1.05-5.16 per 10-year increase; P = .038), patients with advanced clinical T classification (HR, 5.78; 95% CI, 1.60-20.8; P = .007), and patients who were currently using tobacco (HR, 4.38; 95% CI, 1.07-18.0; P = .04). Disease recurrence was associated with advanced clinical T-classification (HR, 8.32; 95% CI, 3.06-23; P < .0001), current/former alcohol use (HR, 13; 95% CI, 1.33-120; P = .03), and unmarried status (HR, 3.28; 95% CI, 1.20-9.00; P = .02). Patients who remained recurrence free for 5 years had an 8.6% chance of recurrence by 10 years (1-sided 95% CI upper bound, 19%; P = .088). CONCLUSIONS: In this study, prognostic risk factors were identified for patients with HPV-OSCC. The observed recurrence rates between 5 years and 10 years after definitive therapy need to be validated in additional studies to determine whether extended cancer surveillance is warranted in this cancer population.

RESUMEN

PURPOSE OF REVIEW: In revision or posttraumatic rhinoplasty, the quantity and quality of septal cartilage available for grafting is often deficient and auricular cartilage often provides insufficient strength for structural nasal reconstruction. Accordingly, rib cartilage serves as a reliable, abundant source of cartilage for grafting. However, the various sources of rib cartilage carry respective benefits and weaknesses. This review examines recent studies, novel applications and a comparison of the primary sources of rib cartilage, including autologous cartilage, irradiated cadaveric rib and fresh frozen cadaveric cartilage. RECENT FINDINGS: Options for rib cartilage include autologous, irradiated cadaveric rib, and more recently, reports on fresh frozen cadaveric cartilage. Studies continue to conclude that autologous and irradiated donor cartilage carry equivalent results, have similar rates of complication and have a comparable cost profile. SUMMARY: Regardless of the source, rib cartilage plays an important role in structural rhinoplasty, especially in revision cases. Although the risks, benefits and long-term results of autologous and radiated homologous cartilage have been evaluated in observational studies, fresh frozen rib cartilage will need further follow up before widespread use, although preliminary literature shows promise.

RESUMEN

OBJECTIVES/HYPOTHESIS: To create a model of the anatomic distribution, recurrence, and growth patterns of recurrent respiratory papillomatosis (RRP). STUDY DESIGN: Prospective, multi-institutional cohort study. METHODS: Adult patients with a diagnosis of RRP evaluated between August 1, 2018 and February 1, 2021 at six participating centers were invited to enroll. At each office or operating room encounter, laryngologists recorded the location and size of RRP lesions using a 22-region schematic. A generalized linear mixed effects model was used to compare region variations in lesion prevalence and recurrence. RESULTS: The cohort comprised 121 patients: 74% were male, 81% had been diagnosed with adult-onset RRP, and a plurality (34%) had undergone 0 to 3 RRP interventions prior to enrollment. Across the study period, the odds of a lesion occurring in the glottis was significantly higher (odds ratio [OR]: 26.51; 95% confidence interval [CI]: 11.76-59.75, P < .001) compared with all other areas of the larynx and trachea. Within the true vocal folds, the membranous vocal folds had significantly higher odds (OR: 6.16; 95% CI: 2.66-14.30, P < .001) of lesion occurrence compared to the cartilaginous vocal folds. Despite these strong trends in lesion distribution, there were no differences in the odds of lesion recurrence, growth, or in the time to recurrence, between anatomic subsites. CONCLUSIONS: RRP lesions are most likely to occur in the glottis, particularly the membranous vocal folds, compared with other regions of the larynx or trachea. However, all lesions demonstrate similar behavior with respect to recurrence, growth, and time to recurrence regardless of anatomic location. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:2403-2411, 2022.

RESUMEN

PURPOSE OF REVIEW: The strain on healthcare resources in light of the COVID-19 pandemic has forced many head and neck surgeons to explore reconstructive options that may decrease length of stay. Here, we review three common and versatile regional flaps used in head and neck reconstruction that are comparable alternatives to free tissue transfer. RECENT FINDINGS: Initial anatomic descriptions of the facial artery musculocutaneous (FAMM) flap, the supraclavicular artery island flap and the submental artery island flap were published decades ago. Since then, many have proposed modifications to these descriptions to improve technical ease and patient outcomes. Benefits of regional flaps include ease of harvest, comparable outcomes to free tissue microvascular flaps, shorter operative time and hospital length of stay. Drawbacks to regional flaps include limitations to size and reach, partial necrosis, wound dehiscence and surgeon experience. The integrity of the vascular pedicle is also contingent upon vessel preservation during the cancer ablation. SUMMARY: Although a resurgence of regional flaps began well before the COVID-19 pandemic, many institutions began looking for alternatives to free flap reconstruction to conserve healthcare resources and minimize patient hospitalization time in the past year. There has been a revival of regional flaps such as the FAMM, supraclavicular and submental flaps that are valuable reconstructive options for many defects of the head and neck.

RESUMEN

OBJECTIVE: To evaluate inheritance patterns and define the familial clustering rate of idiopathic subglottic stenosis (iSGS). STUDY DESIGN: Retrospective observational study. SETTING: International multicenter collaborative of >30 tertiary care centers. METHODS: Patients with a clinically confirmed iSGS diagnosis within the North American Airway Collaborative's iSGS1000 cohort consented between 2014 and 2018 were eligible for enrollment. Patient demographics and disease severity were abstracted from the collaborative's iSGS longitudinal registry. Pedigrees of affected families were created. RESULTS: A total of 810 patients with iSGS were identified. Positive family history for iSGS was reported in 44 patients in 20 families. The rate of familial clustering in iSGS is 2.5%. Mean age of disease onset is 42.6 years. Of the 44 patients with familial aggregation of iSGS, 42 were female and 2 were male; 13 were mother-daughter pairs and 2 were father-daughter pairs. There were 3 sister-sister pairs. There was 1 niece-aunt pair and 2 groups of 3 family members. One pedigree demonstrated 2 affected mother-daughter pairs, with the mothers being first-degree paternal cousins. Inheritance is non-Mendelian, and anticipation is present in 11 of 13 (84%) parent-offspring pairs. The mean age of onset between parents (48.4 years) and offspring (36.1 years) was significantly different (P = .016). CONCLUSION: This study quantifies the rate of familial clustering of iSGS at 2.5%. Inheritance is non-Mendelian, and disease demonstrates anticipation. These data suggest that there may be a genetic contribution in iSGS.

RESUMEN

We introduce a novel computer-based method to digitally fixate midfacial fractures to facilitate more efficient intraoperative fixation. This article aims to describe a novel computer-based algorithm that can be utilized to model midface fracture reduction and fixation and to evaluate the algorithm's ability to produce images similar to true postoperative images. This is a retrospective review combined with cross-sectional survey from January 1, 2010, to December 31, 2015. This study was performed at a single tertiary care, level-I trauma center. Ten patients presenting with acute midfacial traumatic fractures were evaluated. Thirty-five physicians were surveyed regarding the accuracy of the images obtained using the algorithm. A computer algorithm utilizing AquariusNet (TeraRecon, Inc., Foster City, CA) and Adobe Photoshop (Adobe Systems Inc., San Jose, CA) was developed to model midface fracture repair. Preoperative three-dimensional computed tomographic (CT) images were processed using the algorithm. Fractures were virtually reduced and fixated to generate a virtual postoperative image. A survey comparing the virtual postoperative and the actual postoperative images was produced. A Likert-type scale rating system of 0 to 10 (0 being completely different and 10 being identical) was utilized. Survey participants evaluated the similarity of fracture reduction and fixation plate appearance. The algorithm's capacity for future clinical utility was also assessed. Survey response results from 35 physicians were collected and analyzed to determine the accuracy of the algorithm. Ten patients were evaluated. Fracture types included zygomaticomaxillary complex, LeFort, and naso-orbito-ethmoidal complex. Thirty-four images were assessed by a group of 35 physicians from the fields of otolaryngology, oral and maxillofacial surgery, and radiology. Mean response for fracture reduction similarity was 7.8 ± 2.5 and fixation plate similarity was 8.3 ± 1.9. All respondents reported interest in the tool for clinical use. This computer-based algorithm is able to produce virtual images that resemble actual postoperative images. It has the ability to model midface fracture repair and hardware placement.

RESUMEN

OBJECTIVE: Inflammatory pseudotumor of the temporal bone is a benign, idiopathic inflammatory process that is locally invasive and a cause of significant morbidity. This study reviews our experience with seven patients and is currently the largest series to date. STUDY DESIGN: Retrospective review from January 1, 2014 to January 1, 2016. SETTING: Single tertiary medical center. PATIENTS: There were five male and two female (n = 7) subjects with a diagnosis of temporal bone inflammatory pseudotumor. The mean age at presentation was 41 years old. The most common presenting symptoms were hearing loss (7/7) and headache (4/7). Four patients demonstrated an inflammatory aural polyp. Two patients experienced facial nerve paralysis. INTERVENTION(S): Seven patients underwent computed tomography and six underwent magnetic resonance imaging. Corticosteroids and antibiotics were the initial treatment of choice. Five patients also underwent surgery. As adjuvant therapy, two patients received Rituximab, one patient received radiation, and one received mycophenolate mofetil. MAIN OUTCOME MEASURE(S): Clinical courses were followed with focus on symptoms, disease recurrence, duration, and treatment. Mean follow-up was 17.8 months. RESULTS: The primary lesions demonstrated T2 hypo-intensity and enhancement as well as diffuse dural thickening on magnetic resonance imaging in five of six patients. Histopathology demonstrated chronic inflammation in the setting of hyalinized fibrosis (7/7). All the patients are currently symptomatically stable. CONCLUSION: Inflammatory pseudotumor of the temporal bone can cause devastating effects on neurological function and quality of life. Recognition of characteristic imaging and histopathology can expedite appropriate treatment. Patients may require chronic steroid therapy. Adjunctive therapy with radiation and immuno-modulation are currently being explored.

RESUMEN

BACKGROUND: Eosinophils are thought to play a significant role in nasal polyposis, but the exact mechanism by which they contribute to polyposis remains unclear. Therefore, we proposed to test the hypothesis that peripheral blood eosinophilia (PBE) is a surrogate and biomarker for polyp load. To do this, we examined whether PBE levels correlate with nasal polyp load in a longitudinal manner. METHODS: We retrospectively analyzed the fluctuation of PBE and nasal polyp load in each patient (n = 61) assessed preoperatively, 1-2 months postoperatively, and 3-12 months postoperatively. Nasal polyp load was assessed using computed tomography (CT) scan preoperatively and nasal endoscopy postoperatively. Correlation coefficients were analyzed using parametric statistics. RESULTS: There was a positive correlation between initial preoperative baseline PBE and CT scan staging of polyp load (r = 0.35, p < 0.01). When patients were analyzed longitudinally, we found that the change in PBE correlated with the change in nasal endoscopy scores obtained at or near the same timepoint (r = 0.82, p < 2.0 × 10(-10) ). When nasal polyp load increased with time, we observed a stepwise increase in eosinophil counts (r = 0.37, p < 0.02). CONCLUSIONS: PBE correlates with nasal polyp load. PBE levels may be used along with nasal endoscopy to prospectively follow nasal polyp load postoperatively in chronic rhinosinusitis patients with hyperplastic nasal polyposis who have eosinophilia, asthma, and/or aspirin-exacerbated respiratory disease.
