Head and Neck Cancer in Haiti: A Case Series from Hopital de L'Universite d'Etat d'Haiti.

This manuscript characterizes the demographics, presenting symptoms and risk factors of patients diagnosed with head and neck cancer at Hopital de L'Universite d'Etat d'Haiti (HUEH), Haiti's single largest healthcare facility. We conducted a prospective study of patients who presented to HUEH between January and March of 2016 with a lesion of the head or neck suspicious for cancer. All patients who met eligibility criteria received a biopsy, which was interpreted by a Haitian pathologist and when the specimen was available was confirmed by a team of pathologists from Stanford University. A total of 34 participants were identified. The biopsy-confirmed diagnoses were squamous cell carcinoma (n=7), benign (n=7), large cell lymphoma (n=2), ameloblastoma (n=2), pleomorphic adenoma (n=1), and adenocarcinoma (n=1). Fourteen patients were unavailable for biopsy. Patients with head and neck cancer had a mean age of 63.4 years, were majority male (62.5%), waited on average 10.9 months to seek medical attention, and most commonly presented with T-stage 3 or higher disease (87.5%). By characterizing patterns of head and neck cancer at HUEH we hope to facilitate efforts to improve early detection, diagnosis, and management of this important public health condition.

Otorhinolaryngology/Head and Neck Surgery in a low income country: The Haitian experience.

OBJECTIVE: Little is known regarding the diagnosis and management of pediatric surgical conditions of the head and neck in low-income countries. Haiti, the western hemisphere's poorest country, recently developed its first Otorhinolaryngology (ORL) department at the Hopital de L'Universite d'Etat d'Haiti (HUEH). This manuscript assesses the caseload at HUEH with a special emphasis on pediatric cases, with the aim of characterizing ORL related conditions and their treatments in low-income countries. METHODS: We conducted a retrospective chart review of surgical case logs at HUEH for the calendar year of 2014 and recorded patient age, diagnosis, and surgical intervention for all ORL surgeries. RESULTS: A total of 229 ORL surgeries were performed at HUEH during this time. The average age of the patient was 21.8 years and 54.2% of patients were 18 years or younger. The five most common diagnoses were tonsillar hypertrophy (23.6%), ingested foreign body (18%), mandibular fracture (9.2%), unspecified head or neck mass (6%), and thyroid goiter (4.8%). The five most common surgeries performed were tonsillectomy (23.6%), foreign body retrieval (17.9%), open reduction of mandibular fracture with direct skeletal fixation (6.9%), thyroidectomy (7.9%), and excision of unspecified mass. Trauma accounted for 33.6% of all ORL surgeries. CONCLUSIONS: Diseases related to the head and neck constitute a common yet underserved surgical problem. Strengthening ORL surgical capacity in Haiti should focus on improving capacity for the most common conditions including tonsillar disease, ingested foreign bodies, and facial trauma, as well as improving capacity for rarely performed surgeries, such as ear surgery, nose and sinus surgery, and cancer resections.

Barriers to Surgical Care and Health Outcomes: A Prospective Study on the Relation Between Wealth, Sex, and Postoperative Complications in the Republic of Congo.

BACKGROUND: Approximately thirty percent of the global burden of disease is comprised of surgical conditions. However, five billion people lack access to surgery, with complex factors acting as barriers. We examined whether patient demographics predict barriers to care, and the relation between these factors and postoperative complications in a prospective cohort. METHODS: Participants included people presenting to a global charity in Republic of Congo with a surgical condition between August 2013 and May 2014. The outcomes were self-reported barrier to care and postoperative complications documented by medical record. Logistic regression was used to adjust for covariates. RESULTS: Of 1237 patients in our study, 1190 (96.2 %) experienced a barrier to care and 126 (10.2 %) experienced a postoperative complication. The most frequently reported barrier was cost (73 %), followed by lack of provider (8.2 %). Greater wealth was associated with decreased odds of cost as a barrier (OR 0.72 [0.57, 0.90]). Greater wealth (OR 1.52 [1.03, 2.25]) and rural home location (OR 3.35 [1.16, 9.62]) were associated with increased odds of no surgeon being available. Cost as a barrier (OR 2.82 [1.02, 7.77]), female sex (OR 3.45 [1.62, 7.33]), and lack of surgeon (OR 5.62 [1.68, 18.77]) were associated with increased odds of postoperative complication. Patient wealth was not associated with odds of postoperative complication. CONCLUSIONS: Barriers to surgery were common in Republic of Congo. Patient wealth and home location may predict barriers to surgery. Addressing gender disparities, access to providers, and patient perception of barriers in addition to removal of barriers may help maximize patient health benefits.

Head and neck cancer in South Asia: Macroeconomic consequences and the role of the head and neck surgeon.

BACKGROUND: Head and neck cancer constitutes a substantial portion of the burden of disease in South Asia, and there is an undersupply of surgical capacity in this region. The purpose of this study was to estimate the economic welfare losses due to head and neck cancer in India, Pakistan, and Bangladesh in 2010. METHODS: We used publicly available estimates of head and neck cancer morbidity and mortality along with a concept termed the value of a statistical life to estimate economic welfare losses in the aforementioned countries in 2010. RESULTS: Economic losses because of head and neck cancer in India, Pakistan, and Bangladesh totaled $16.9 billion (2010 US dollars [USD]), equivalent to 0.26% of the region's economic output. Bangladesh, the poorest country, experienced the greatest proportional losses. CONCLUSION: The economic consequences of head and neck cancer in South Asia are significant, and building surgical capacity is essential to begin to address this burden. © 2016 Wiley Periodicals, Inc.

Head and neck cancer in South Asia: macroeconomic consequences and the role of surgery.

BACKGROUND: Head and neck cancer, for which the diagnosis and treatment are often surgical, comprises a substantial proportion of the burden of disease in South Asia. Further, estimates of surgical volume suggest this region faces a critical shortage of surgical capacity. We aimed to estimate the total economic welfare losses due to the morbidity and mortality of head and neck cancer in India, Pakistan, and Bangladesh for 1 year (2010). METHODS: We used publicly available estimates from the Institute for Health Metrics and Evaluation regarding the morbidity and mortality of head and neck cancer in India, Pakistan, and Bangladesh, along with an economic concept termed the value of a statistical life, to estimate total economic welfare losses due to head and neck cancer in the aforementioned countries in the year 2010. The counterfactual scenario is absence of disease. Sensitivity analyses were done with regard to how the value of a statistical life changes with income. FINDINGS: In 2010, the most conservative estimate of economic welfare losses due to head and neck cancer in the three studied countries is US$16·9 billion (2010 USD, PPP), equivalent to 0·26% of their combined gross domestic product (GDP). The welfare losses experienced by the population younger than 70 years of age accounted for US$15·2 billion (90% of the total losses). When adjusted for the size of their respective economies, Bangladesh, the poorest of the three countries, incurred the greatest loss (US$930 million), equivalent to 0·29% of its GDP. India and Pakistan experienced welfare losses of US$14·1 billion and US$1·9 billion, respectively. These figures are equivalent to 0·26% of the GDP for both countries. Oropharyngeal and hypopharyngeal cancer made up the largest share of the total burden at 39% (US$6·6 billion), followed closely by oral cavity cancer at 34% (US$5·7 billion). INTERPRETATION: The burden of non-communicable diseases, to which cancer contributes greatly, is growing at a rapid pace in South Asia. Head and neck cancer is a leading cause of cancer-related mortality in this region, and this study suggests that the associated economic welfare losses, estimated to be US$16·9 billion in 2010 alone, are substantial. A number of strategies are available to address this burden. Surgery, as part of a multidisciplinary approach that includes radiation therapy and chemotherapy, plays a central part in the diagnosis and treatment of head and neck cancer, and building surgical capacity, which offers large economies of scope and scale, can not only address the burden of head and neck cancer, but also create a platform for beginning to confront the rising tide of non-communicable diseases. FUNDING: None.

Ovine model for auricular reconstruction: porous polyethylene implants.

OBJECTIVES: We developed a large animal model for auricular reconstruction with engineered cartilage frameworks and evaluated the performance of porous polyethylene auricular implants in this model. METHODS: Eighteen high-density porous polyethylene auricular frameworks were implanted subcutaneously in the infra-auricular areas of 9 sheep. The implants were harvested 17 weeks later for gross and histologic examination. The perioperative and postoperative courses were carefully documented. RESULTS: Five implants became exposed, and 2 implants needed to be removed at 7 weeks. Additionally, 1 infected implant was removed at 2 weeks. Seromas developed in 2 implants because of drain failures and were drained successfully during the first postoperative week. There were no other surgical site complications. The remaining 10 implants had an acceptable cosmetic appearance at 17 weeks. CONCLUSIONS: The perioperative complication rate in the ovine porous polyethylene auricular implant model was higher than that reported for auricular reconstructions in humans. The implant exposures were likely caused by ischemia and excessive stress on the thin overlying skin, because vascularized flap coverage was not used. The histologic findings were comparable to the results reported for other animal models. This large animal model is appropriate for auricular reconstruction experiments, including engineered constructs.

Objective outcomes analysis following microvascular gracilis transfer for facial reanimation: a review of 10 years' experience.

IMPORTANCE Objective assessment of smile outcome after microvascular free gracilis transfer is challenging, and quantification of smile outcomes in the literature is inconsistent. OBJECTIVE To report objective excursion and symmetry outcomes from a series of free gracilis cases and investigate the predictive value of intraoperative measurements on final outcomes. DESIGN, SETTING, AND PARTICIPANTS A retrospective medical chart review was undertaken of all patients who underwent microvascular free gracilis transfer for smile at our institution over the past 10 years. MAIN OUTCOMES AND MEASURES Outcome measures included the following: smile excursion, angle of smile with respect to the vertical midline, and facial symmetry during repose and with smile. Measurements were obtained using an automated tool for assessment of facial landmarks (FACE-Gram). An exhaustive set of intraoperative parameters including degree of recoil of the gracilis muscle following harvest, the degree to which the muscle foreshortened during stimulation of the obturator nerve, final stretched length of the inset muscle, surgeon assessment of neurorrhaphy and pulse pressure, ischemia time, number of sutures used during neurorrhaphy, nerve used to innervate the flap, and surgeon assessment of oral commissure overcorrection were recorded and placed into a linear regression model to investigate correlations with smile. RESULTS From March 2003 to March 2013, 154 microvascular free gracilis transfers were performed for facial reanimation at our institution, 14 (9%) of which were deemed failures. Of the remaining 140 flaps, 127 fulfilled inclusion criteria and constituted the study cohort. Smile excursion, angle excursion, and symmetry of the oral commissure at repose and with smile all improved following gracilis free flap (P < .05). Associations between selected outcomes measures and intraoperative gracilis measurements were identified. CONCLUSIONS AND RELEVANCE Facial reanimation using free gracilis transfer results in quantifiable improvements in oral commissure excursion and facial symmetry both at rest and with smiling. Associations between contractility and internal recoil of the flap and final outcome were identified. LEVEL OF EVIDENCE 4

A comparison of facial nerve grading systems.

PURPOSE: This study aimed to compare a computerized tool to standard objective clinical scales for global and zone-specific assessment of facial nerve function. METHODS: This was a retrospective review of 77 patients with facial paralysis who underwent facial videography. Videos were independently scored by 3 facial nerve specialists using the House-Brackmann Scales (HBI and HBII). Digital scoring was performed with Facogram software. Scores were recorded and compared using intraclass and Pearson (r) correlations. RESULTS: Interobserver correlation was high with HBII, with overall scores in excellent agreement (intraclass correlation range, 0.78-0.95; P ≤ 0.0001). There were strong correlations between Facogram and HBII (r ≥ 0.67, P ≤ 0.0001) and strong intraobserver correlations between HBI and HBII (r ≥ 0.71, P ≤ 0.0001). The HBII required more clinician time [mean (SD), 72 (21) seconds per case], compared with Facogram, which did not require any clinician time. CONCLUSIONS: An automated, zone-specific facial analysis tool can eliminate clinician subjectivity and allow standardized assessment of facial paralysis.

Surgical site infections after gracilis free flap reconstruction for facial paralysis.

Compared with other free tissue transfer procedures, the gracilis free muscle transfer (GFMT) for facial reanimation is unique in that the recipient site is typically uninvolved by malignancy or infection. In this study, the authors examined the incidence, bacteriology, and outcomes of surgical site infection (SSI) after gracilis free muscle transfer for facial reanimation. From 2003 to 2011, 105 patients underwent 107 GFMT operations, with 6 SSIs. All cases of infection occurred in patients receiving clindamycin, levofloxacin, and/or cefazolin perioperatively. None of the patients who received ampicillin-sulbactam developed an SSI. Surgical site cultures grew oral flora, including α-hemolytic streptococci, Haemophilus parainfluenzae, Fusobacterium and Neisseria species, and coagulase-negative staphylococci. Notably, there were no methicillin-resistant Staphylococcus aureus (MRSA) infections. These data may have implications for the optimal perioperative antibiotic choice in facial reanimation cases. Further study is needed to determine the ideal antibiotic regimen for this category of free flap surgeries.

Platysmectomy: an effective intervention for facial synkinesis and hypertonicity.

OBJECTIVES: To describe a procedure to permanently address platysmal synkinesis and hypertonicity and to report changes in quality of life associated with platysmectomy using the Facial Clinimetric Evaluation instrument. METHODS: Chemodenervation significantly relieves platysmal synkinesis in almost all patients with significant face and neck synkinesis associated with dynamic facial expressions. We recently began to offer platysmectomy as part of a permanent solution to chronic superficial torticollis-like neck symptoms. For a 10-month period, 24 patients underwent the procedure, and preoperative and postoperative Facial Clinimetric Evaluation data were obtained from 21 patients (88%). RESULTS: In 19 patients, platysmectomy was performed using local anesthesia without sedation. In the remaining 5 patients, platysmectomy was performed using general anesthesia concurrent with free gracilis transfer for smile reanimation. No intraoperative or postoperative complications occurred. Overall, the patients' quality of life significantly improved after platysmectomy (P = .02). CONCLUSION: Platysmectomy is straightforward and seems effective in treating neck synkinesis associated with chronic hypertonic platysmal activity.

Free gracilis transfer for smile in children: the Massachusetts Eye and Ear Infirmary Experience in excursion and quality-of-life changes.

BACKGROUND: Free muscle transfer for facial reanimation has become the standard of care in recent decades and is now the cornerstone intervention for dynamic smile reanimation. We sought to quantify smile excursion and quality-of-life (QOL) changes in our pediatric free gracilis recipients following reanimation. METHODS: We quantified gracilis muscle excursion in 17 pediatric patients undergoing 19 consecutive pediatric free gracilis transplantation operations, using our validated SMILE program, as an objective measure of functional outcome. These were compared against excursion measured the same way in a cohort of 17 adults with 19 free gracilis operations. In addition, we prospectively evaluated QOL outcomes in these children using the Facial Clinimetric Evaluation (FaCE) instrument. RESULTS: The mean gracilis excursion in our pediatric free gracilis recipients was 8.8 mm ± 5.0 mm, which matched adult results, but with fewer complete failures of less than 2-mm excursion, with 2 (11%) and 4 (21%), respectively. Quality-of-life measures indicated statistically significant improvements following dynamic smile reanimation (P = .01). CONCLUSIONS: Dynamic facial reanimation using free gracilis transfer in children has an acceptable success rate, yields improved commissure excursion, and improves QOL in the pediatric population. It should be considered first-line therapy for children with lack of a meaningful smile secondary to facial paralysis.

Surgical treatment of the periocular complex and improvement of quality of life in patients with facial paralysis.

OBJECTIVE: A devastating sequela of facial paralysis is the inability to close the eye. The resulting loss of corneal protection can potentially lead to severe consequences. Eyelid weight placement, lower eyelid suspension, and brow ptosis correction are frequently performed to protect the eye. We sought to measure and report the change in quality of life (QOL) after surgical treatment of the periocular complex, using the validated Facial Clinimetric Evaluation (FaCE) QOL instrument. METHODS: From March 2009 to May 2010, 49 patients presenting to the Facial Nerve Center with paralytic lagophthalmos requiring intervention were treated with static periocular reanimation. Thirty-seven of the patients completed preoperative and postoperative FaCE surveys. RESULTS: Overall QOL, measured by the FaCE instrument, significantly improved following static periocular treatment. Mean FaCE scores increased from 44.1 to 52.7 (P < .001). Patients also reported a significant decrease in the amount of time their eye felt dry, irritated, or scratchy (P < .001). The amount of artificial tears and/or ointment also significantly decreased (P = .03). There were 2 cases of localized cellulitis with 1 eyelid weight extrusion. CONCLUSIONS: We report the first series of postoperative QOL changes following static periocular treatment for paralytic lagophthalmos. Patients report a notable improvement in periocular comfort and overall QOL.

A systematic algorithm for the management of lower lip asymmetry.

PURPOSE: An asymmetric smile, caused by loss of function of the lip depressors, can be functionally and cosmetically debilitating. Although some surgeons report excellent results with muscle transfer to the lower lip, many facial reanimation surgeons find that dynamic techniques do not consistently address the lower lip. Our objectives were to retrospectively review our outcomes after treatment of the asymmetric lower lip, and to propose a progressive, stepwise algorithm for the management of lower lip asymmetry in facial paralysis. MATERIAL/METHODS: Retrospective chart review was performed on all patients treated in a multidisciplinary facial nerve center with lower lip asymmetry over an eighteen month period. Treatment ranged from a temporary trial of lidocaine, to chemodenervation with botulinum toxin, to pedicled digastric muscle transfer, and/or resection of the nonparetic depressor labii inferioris (DLI). RESULTS: Fifty-seven patients were treated with chemodenervation with botulinum toxin, four with anterior belly of the digastric transfer, and 3 with DLI resection. All patients with DLI resection had undergone chemodenervation to the contralateral lower lip with botulinum toxin and were pleased with the appearance of their smile. CONCLUSIONS: We have found that lower lip asymmetry is optimally managed by adherence to a standardized protocol that offers patients insight into the likely outcome of chemodenervation or surgery and progresses systematically from the reversible to the irreversible. We present our algorithm for the management of the asymmetric lower lip, which reflects this graduated approach and has resulted in high patient satisfaction.

Good correlation between original and modified House Brackmann facial grading systems.

OBJECTIVES/HYPOTHESIS: Subjective scales of facial function were plagued with reporting variations until the House-Brackmann scale was described in 1985. Despite its utility, weaknesses were identified, including noninclusion of synkinesis phenomena and insensitivity to segmental weakness. Therefore, the scale was recently revised to address these weaknesses. The objective of this investigation was to determine agreement between the original and the updated House-Brackmann scales. STUDY DESIGN: Prospective clinical trial. METHODS: Fifty consecutive new facial paralysis patients underwent standardized facial videography while performing facial movements. Video clips were scored by three independent facial nerve clinicians. The time it took to produce a score for each method was tracked. Interobserver correlations were calculated, and comparisons were made between scores by using the original and modified House-Brackmann scales. RESULTS: : Interobserver correlation was high for both House-Brackmann scales. Overall scores were in excellent agreement (difference of 0.1 ± 0.5, no statistical difference), although the modified scale took substantially longer to calculate (120 seconds ± 20 seconds vs. 30 seconds ± 10 seconds, P < .001). CONCLUSIONS: We found substantial grading correlation between the original and the newly modified House-Brackmann scales. Because of specific zonal and synkinesis scoring, the modified scale took longer to score.

Thin-profile platinum eyelid weighting: a superior option in the paralyzed eye.

BACKGROUND: A devastating sequela of facial paralysis is the inability to close the eye. The resulting loss of corneal protection can lead to exposure keratitis, corneal ulceration, and potentially permanent vision loss. Methods to address lagophthalmos historically have included tarsorrhaphy, lid weighting, levator palpebrae superioris lengthening, chemodenervation to yield protective ptosis, and the placement of magnetic eyelid springs. The gold eyelid weight, introduced nearly 50 years ago, continues to enjoy immense popularity, despite high complication rates and nearly uniform visibility under the skin. The authors hypothesized that a commercially available, thin platinum weight would combat the visibility of the thicker gold weights and herein compare complication rates and visibility rates with literature-reported data for gold weights. METHODS: Beginning in 2004, 100 consecutive patients presenting to the authors' Facial Nerve Center with paralytic lagophthalmos requiring intervention were treated with thin-profile platinum eyelid weights. Ninety-six percent of cases were performed under local anesthesia in the office setting. RESULTS: Median follow-up was 22 months. In 102 weights placed, there have been six complications (5.9 percent): three extrusions, two capsule formations, and one case of astigmatism. All of the extrusions involved irradiated patients with parotid malignancies. CONCLUSIONS: The authors report the first large series of thin-profile platinum eyelid weight implantations for the treatment of lagophthalmos. This implant significantly reduces both capsule formation phenomena and extrusion compared with gold weights and should be considered as alternative to the more conventional gold implants.

Bilateral simultaneous free gracilis muscle transfer: a realistic option in management of bilateral facial paralysis.

OBJECTIVES: Bilateral facial paralysis patients have oral incompetence, poor articulation, and dental caries. This problem is frequently addressed by performing staged gracilis transplants without specific oral sphincter reconstruction. The purpose of this study is to describe the technique of bilateral simultaneous free gracilis muscle transfer with oral sphincter reconstruction, for one-stage facial reanimation in patients with bilateral facial paralysis. STUDY DESIGN: Case series. METHODS/RESULTS: One-stage bilateral gracilis transfer was performed in three patients with bilateral facial paralysis. Muscle transplants produced a meaningful smile in all transferred muscles. All patients reported improved speech and decreased drooling. CONCLUSIONS: Bilateral gracilis transplants with reconstruction of the oral commissure is a realistic option in management of the bilaterally paralyzed face. In this small series, it appears to improve oral competence, restore smiling, and contribute favorably to lower lip support. This technique has been made more feasible because the operative time for free tissue transfer has continuously declined with the use of two-team surgery, improved microsurgical techniques, and the advent of venous coupling devices.
