RESUMEN
Due to respiratory weakness, late-stage Duchenne muscular dystrophy (DMD) patients may suffer from chronic aspiration, which is sometimes treated using tracheostomy. However, definitive laryngectomy has not been described in the literature as an aspiration prevention modality in DMD, especially in patients with contraindications to tracheostomy. A case is presented for a patient with advanced stage Duchenne muscular dystrophy suffering from chronic aspiration pneumonia and excessive oral secretions who became ventilator dependent. A tracheostomy was placed, but was noted to have excessive secretions and high cuff pressures, which have been known to be associated with worsened swallow dysfunction as well as tracheoinnominate fistula. The patient therefore was considered for total laryngectomy, which he underwent successfully. Post-operatively, the patient was noted to have improved subjective quality of life, engaged in an oral diet, and had less secretions surrounding his tracheostoma post-operatively. Aspiration prevention surgeries are done to improve quality of life by improving oral intake, decreasing the need for frequent suctioning, and can sometimes allow for speech. It is important to consider quality of life for DMD patients as more of these patients are living into their 30s with the aid of mechanical ventilation. Laryngectomy is a surgery that can definitively correct chronic aspiration while allowing for oral intake. Laryngoscope, 134:3677-3678, 2024.

STUDY OBJECTIVES: Previous studies reported that the apnea-hypopnea index was similar in young adult Black and White participants. However, whether this similarity reflects an analogous combination of apneas and hypopneas is unknown. Likewise, the physiological mechanisms underlying this similarity has not been explored. METHODS: 60 Black and 48 White males completed the study. After matching for age and body mass index, 41 participants remained in each group. All participants completed a sleep study. Subsequently, standard sleep indices along with loop gain and the arousal threshold were determined. In addition, airway collapsibility (24 of 60 and 14 of 48 participants) and the hypoxic ventilatory response during wakefulness (30 of 60 and 25 of 48 participants) was measured. RESULTS: The apnea-hypopnea index was similar in Blacks and Whites (p = .140). However, the index was comprised of more apneas (p = .014) and fewer hypopneas (p = .025) in Black males. These modifications were coupled to a reduced loop gain (p = .0002) and a more collapsible airway (p = .030). These differences were independent of whether or not the groups were matched. For a given hypoxic response, loop gain was reduced in Black compared to White males (p = .023). CONCLUSIONS: Despite a similar apnea-hypopnea index, more apneas and fewer hypopneas were evident in young adult Black compared to White males. The physiological mechanisms that contribute to these events were also different between groups. Addressing these differences may be important when considering novel therapeutic approaches to eliminate apnea in Black and White participants.

BACKGROUND: Initial primary head and neck cancer (IPHNC) is associated with second primary lung cancer (SPLC). We studied this association in a population with a high proportion of African American (AA) patients. METHODS: Patients with IPHNC and SPLC treated between 2000 and 2017 were reviewed for demographic, disease, and treatment-related characteristics and compared to age-and-stage-matched controls without SPLC. Logistic and Cox regression models were used to analyze the relationship of these characteristics with the development of SPLC and overall survival (OS). RESULTS: Eighty-seven patients and controls were compared respectively. AA race was associated with a significantly higher risk of developing SPLC (OR 2.92, 95% CI 1.35-6.66). After correcting for immortal time bias, patients with SPLC had a significantly lower OS when compared with controls (HR 0.248, 95% CI 0.170-0.362). CONCLUSIONS: We show that AA race is associated with an increased risk of SPLC after IPHNC; reasons of this increased risk warrant further investigation.

Introduction: Resting minute ventilation and ventilation during and following hypoxia may be enhanced following daily exposure to mild intermittent hypoxia (MIH). In contrast, resting systolic blood pressure (SBP) is reduced following daily exposure to MIH. However, it is presently unknown if the reduction in resting SBP following daily exposure, is coupled with reduced SBP responses during and after acute exposure to MIH. Methods: Participants with obstructive sleep apnea (OSA) and hypertension (n = 10) were exposed to twelve 2-min bouts of MIH (oxygen saturation-87%)/day for 15 days. A control group (n = 6) was exposed to a sham protocol during which compressed air (i.e., FIO2 = 0.21) was inspired in place of MIH. Results: The hypoxic ventilatory response (HVR) and hypoxic systolic blood pressure response (HSBP) increased from the first to the last hypoxic episode on the initial (HVR: 0.08 ± 0.02 vs. 0.13 ± 0.02 L/min/mmHg, p = 0.03; HSBP: 0.13 ± 0.04 vs. 0.37 ± 0.06 mmHg/mmHg, p < 0.001) and final (HVR: 0.10 ± 0.01 vs. 0.15 ± 0.03 L/min/mmHg, p = 0.03; HSBP: 0.16 ± 0.03 vs. 0.41 ± 0.34 mmHg/mmHg, p < 0.001) day. The magnitude of the increase was not different between days (p ≥ 0.83). Following exposure to MIH, minute ventilation and SBP was elevated compared to baseline on the initial (MV: 16.70 ± 1.10 vs. 14.20 ± 0.28 L/min, p = 0.01; SBP: 167.26 ± 4.43 vs. 151.13 ± 4.56 mmHg, p < 0.001) and final (MV: 17.90 ± 1.25 vs. 15.40 ± 0.77 L/min, p = 0.01; SBP: 156.24 ± 3.42 vs. 137.18 ± 4.17 mmHg, p < 0.001) day. The magnitude of the increases was similar on both days (MV: 3.68 ± 1.69 vs. 3.22 ± 1.27 L/min, SBP: 14.83 ± 2.64 vs. 14.28 ± 1.66 mmHg, p ≥ 0.414). Despite these similarities, blood pressure at baseline and at other time points during the MIH protocol was reduced on the final compared to the initial day (p ≤ 0.005). Conclusion: The ventilatory and blood pressure responses during and following acute MIH were similar on the initial and final day of exposure. Alternatively, blood pressure was down regulated, while ventilation was similar at all time points (i.e., baseline, during and following MIH) after daily exposure to MIH.
RESUMEN
Rationale: Daily exposure to mild intermittent hypoxia (MIH) may elicit beneficial cardiovascular outcomes. Objectives: To determine the effect of 15 days of MIH and in-home continuous positive airway pressure treatment on blood pressure in participants with obstructive sleep apnea and hypertension. Methods: We administered MIH during wakefulness 5 days/week for 3 weeks. The protocol consisted of twelve 2-minute bouts of hypoxia interspersed with 2 minutes of normoxia. End-tidal carbon dioxide was maintained 2 mm Hg above baseline values throughout the protocol. Control participants were exposed to a sham protocol (i.e., compressed air). All participants were treated with continuous positive airway pressure over the 3-week period. Results are mean ± SD. Measurements and Main Results: Sixteen male participants completed the study (experimental n = 10; control n = 6). Systolic blood pressure at rest during wakefulness over 24 hours was reduced after 15 days of MIH (142.9 ± 8.6 vs. 132.0 ± 10.7 mm Hg; P < 0.001), but not following the sham protocol (149.9 ± 8.6 vs. 149.7 ± 10.8 mm Hg; P = 0.915). Thus, the reduction in blood pressure from baseline was greater in the experimental group compared with control (-10.91 ± 4.1 vs. -0.17 ± 3.6 mm Hg; P = 0.003). Modifications in blood pressure were accompanied by increased parasympathetic and reduced sympathetic activity in the experimental group, as estimated by blood pressure and heart rate variability analysis. No detrimental neurocognitive and metabolic outcomes were evident following MIH. Conclusions: MIH elicits beneficial cardiovascular and autonomic outcomes in males with OSA and concurrent hypertension. Clinical trial registered with www.clinicaltrials.gov (NCT03736382).

INTRODUCTION: This article reports on the effects of an early outbreak during the COVID-19 pandemic on visit volume and telehealth use by various specialists at a comprehensive cancer center. MATERIALS AND METHODS: The number of on-site and telehealth visits (THV) for medical and surgical specialties were obtained from scheduling software. RESULTS: Total visits were most drastically limited in April 2020 to a low point of 3139; THV made up 28% of all visits. For head and neck surgery, THV made up 54% and 30% of visits in April and May, respectively. Other specialties, such as psychiatry and palliative care, had higher levels of THV. For most specialties, the rebound in June through September did not make up for visits lost during the outbreak, and fiscal year (FY) 2020 had a 9% loss from FY 2019 with 5786 fewer total annual visits across all specialties. CONCLUSIONS: While telemedicine was a helpful part of this cancer center's response to the initial COVID-19 surge, it was not able to replace the in-person services offered at the same center. The main strategy of physicians at this cancer center was to defer care, with telemedicine being an auxiliary response.

OBJECTIVES/HYPOTHESIS: To determine the association between findings of blinded reviews of preoperative drug-induced sleep endoscopy (DISE) and outcomes of hypoglossal nerve stimulation (HNS) for obstructive sleep apnea (OSA). STUDY DESIGN: Cohort study. METHODS: A retrospective, multicenter cohort study of 343 adults who underwent treatment of OSA with HNS from 10 academic medical centers was performed. Preoperative DISE videos were scored by four blinded reviewers using the VOTE Classification and evaluation of a possible primary structure contributing to airway obstruction. Consensus DISE findings were examined for an association with surgical outcomes based on therapy titration polysomnogram (tPSG). Treatment response was defined by a decrease of ≥50% in the apnea-hypopnea index (AHI) to <15 events/hour. RESULTS: Study participants (76% male, 60.4 ± 11.0 years old) had a body mass index of 29.2 ± 3.6 kg/m2 . AHI decreased (35.6 ± 15.2 to 11.0 ± 14.1 events/hour; P < .001) on the tPSG, with a 72.6% response rate. Complete palate obstruction (vs. none) was associated with the greatest difference in AHI improvement (-26.8 ± 14.9 vs. -19.2 ± 12.8, P = .02). Complete (vs. partial/none) tongue-related obstruction was associated with increased odds of treatment response (78% vs. 68%, P = .043). Complete (vs. partial/none) oropharyngeal lateral wall-related obstruction was associated with lower odds of surgical response (58% vs. 74%, P = .042). CONCLUSIONS: The DISE finding of primary tongue contribution to airway obstruction was associated with better outcomes, whereas the opposite was true for the oropharyngeal lateral walls. This study suggests that the role for DISE in counseling candidates for HNS extends beyond solely for excluding complete concentric collapse related to the velum.

OBJECTIVE: To compare patients with moderate-severe obstructive sleep apnea (OSA) undergoing traditional single and multilevel sleep surgery to those undergoing upper airway stimulation (UAS). STUDY DESIGN: Case control study comparing retrospective cohort of patients undergoing traditional sleep surgery to patients undergoing UAS enrolled in the ADHERE registry. SETTING: 8 multinational academic medical centers. SUBJECTS AND METHODS: 233 patients undergoing prior single or multilevel traditional sleep surgery and meeting study inclusion criteria were compared to 465 patients from the ADHERE registry who underwent UAS. We compared preoperative and postoperative demographic, quality of life, and polysomnographic data. We also evaluated treatment response rates. RESULTS: The pre and postoperative apnea hypopnea index (AHI) was 33.5 and 15 in the traditional sleep surgery group and 32 and 10 in the UAS group. The postoperative AHI in the UAS group was significantly lower. The pre and postoperative Epworth sleepiness scores (ESS) were 12 and 6 in both the traditional sleep surgery and UAS groups. Subgroup analysis evaluated those patients undergoing single level palate and multilevel palate and tongue base traditional sleep surgeries. The UAS group had a significantly lower postoperive AHI than both traditional sleep surgery subgroups. The UAS group had a higher percentage of patients reaching surgical success, defined as a postoperative AHI <20 with a 50% reduction from preoperative severity. CONCLUSION: UAS offers significantly better control of AHI severity than traditional sleep surgery. Quality life improvements were similar between groups.

PURPOSE: To determine the factors that sleep medicine/surgery fellowship program directors look for in applicants. METHODS: Program directors from 9 sleep medicine/surgery fellowship programs in the USA were sent an anonymous online survey. They were asked to select the five most important academic factors (of a list of 17) when evaluating potential fellowship candidates, then rank those five in order of importance. They were then asked to do the same for the most important subjective criteria (of a list of 12). RESULTS: Eight of 10 survey responses met inclusion criteria. Of the academic factors, strength of letters of recommendation, reputation of letter writer, and letters from sleep surgeons ranked highest. As for the subjective criteria, faculty assessment of the applicant on interview was ranked highest, followed by initiative and personality "fit" with the program. The reputation of an applicant's residency was ranked as more important than the reputation of their medical school. An applicant's performance in residency was assessed as more predictive of their performance in fellowship than performance during the interview process or position on the rank order list for the match. Only one program has a United States Medical Licensing Examination (USMLE) Step, and a different program has an Otolaryngology Training Examination (OTE) score cutoff. CONCLUSION: Letters of recommendation and interview are the most important factors in the selection process for hybrid sleep medicine and surgery fellowship programs, followed by research and residency program reputation. Sleep surgery-specific experience is helpful.

Abstract Introduction The COVID-19 pandemic has led to a reduction in surgical and clinical volume, which has altered the traditional training experience of the otolaryngology resident. Objective To describe the strategies we utilized to maximize resident education as well as ensure patient and staff safety during the pandemic. Methods We developed a system that emphasized three key elements. First and foremost, patient care remained the core priority. Next, clinical duties were restructured to avoid unnecessary exposure of residents. The third component was ensuring continuation of resident education and maximizing learning experiences. Results To implement these key elements, our residency divided up our five hospitals into three functional groups based on geographical location and clinical volume. Each team works for three days at their assigned location before being replaced by the next three-person team at our two busiest sites. Resident teams are kept completely separate from each other, so that they do not interact with those working at other sites. Conclusions Despite the daily challenges encountered as we navigate through the COVID-19 pandemic, our otolaryngology residency program has been able to establish a suitable balance between maintenance of resident safety and well-being without compromise to patient care.

RESUMEN
We investigated whether time of day affects loop gain (LG) and the arousal threshold (AT) during non-rapid eye movement (NREM) sleep. Eleven men with obstructive sleep apnea (apnea-hypopnea index > 5 events/h) completed a constant-routine protocol that comprised 3-h sleep sessions in the evening [10 PM (1) to 1 AM], morning (6 AM to 9 AM), afternoon (2 PM to 5 PM), and subsequent evening [10 PM (2) to 1 AM]. During each sleep session LG and the AT were measured during NREM sleep with a model-based approach. Our results showed the presence of a rhythmicity in both LG (P < 0.0001) and the AT (P < 0.001) over a 24-h period. In addition, LG and the AT were greater in the morning compared with both evening sessions [6 AM vs. 10 PM (1) vs. 10 PM (2): LG (1 cycle/min): 0.71 ± 0.23 vs. 0.60 ± 0.22 (P = 0.01) vs. 0.56 ± 0.10 (P < 0.001), AT (fraction of eupneic breathing): 1.45 ± 0.47 vs. 1.28 ± 0.36 (P = 0.02) vs. 1.20 ± 0.18 (P = 0.001)]. No difference in LG and the AT existed between the evening sessions (LG: P = 0.27; AT: P = 0.24). LG was correlated to measures of the hypocapnic ventilatory response (i.e., a measure of chemoreflex sensitivity) (r = 0.72 and P = 0.045) and the critical closing pressure (i.e., a measure of airway collapsibility) (r = 0.77 and P = 0.02) that we previously published. We conclude that time of day, independent of hallmarks of sleep apnea, affects LG and the AT during NREM sleep. These modifications may contribute to increases in breathing instability in the morning compared with other periods throughout the day/night cycle in individuals with obstructive sleep apnea. In addition, efficaciousness of treatments for obstructive sleep apnea that target LG and the AT may be modified by a rhythmicity in these variables.NEW & NOTEWORTHY Loop gain and the arousal threshold during non-rapid eye movement (NREM) sleep are greater in the morning compared with the afternoon and evening. Loop gain measures are correlated to chemoreflex sensitivity and the critical closing pressure measured during NREM sleep in the evening, morning, and afternoon. Breathing (in)stability and efficaciousness of treatments for obstructive sleep apnea may be modulated by a circadian rhythmicity in loop gain and the arousal threshold.

A literature review was conducted regarding the assessment and treatment of postoperative pain following surgery for obstructive sleep apnea (OSA). Given the risks of opioid use by patients with OSA, special attention to opioid risk reduction and avoidance is warranted in this population. The results of this review demonstrate the existence of a body of evidence that supports the use of nonopioid analgesics and nonpharmacologic approaches pain management. Strategies for managing postoperative pain should emphasize the use of local anesthetic infiltration, nonsteroidal antiinflammatory drugs, acetaminophen, topical analgesics, surgical wound cooling, and when necessary, safer opioid medications, such as tramadol and intranasal butorphanol.

OBJECTIVE: To perform an evidence-based systematic review evaluating perioperative analgesia, including opioid alternatives, used for patients undergoing thyroidectomy and parathyroidectomy. METHODS: A comprehensive literature search from 1997 to January 2018 of Pubmed, Cochrane, and EmBase libraries was performed for studies reporting analgesic administration following thyroid or parathyroid surgery. This systematic review was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Studies were evaluated for level of evidence and given a Jadad score to assess for risk of bias. Outcomes gathered included postoperative pain scores, time to rescue analgesia, rescue analgesic consumption, and adverse events. RESULTS: Thirty-eight randomized controlled trials met inclusion criteria. The GRADE criteria determined the overall evidence to be moderate-high. Studies utilizing NSAIDs reported reduced requirements for rescue analgesics. Acetaminophen studies presented with conflicting data on effectiveness. Gabapentinoid studies demonstrated lower pain scores and an increased time to rescue analgesic. Local anesthetics were effective at decreasing Visual Analogue Scale (VAS) and Numeric Rating Scale (NRS) pain scores while also reducing rescue analgesic consumption. Ketamine was shown to increased postoperative nausea and vomiting. NSAIDs and local anesthetic studies had an aggregate grade of evidence A, while all others had grade B evidence. CONCLUSION: There is significant evidence supporting the use of NSAIDs and local anesthetics in the perioperative period for pain management for thyroid and parathyroid surgeries. Acetaminophen, gabapentinoid and ketamine have some supporting evidence and may serve as adequate alternatives. Further multi-institutional RCTs are warranted to delineate optimal analgesic regimens. LEVEL OF EVIDENCE: NA.

Anaplastic thyroid carcinoma (ATC) is a rare type of thyroid neoplasm. However, it is one of the most aggressive forms of malignancy accounting for approximately 50% of mortality associated with all thyroid cancers. Here we report two cases of ATC treated with immune checkpoint inhibitors. Next generation sequencing identified BRAFV600E mutation in one of the patients who also derived benefit from BRAF targeted therapy. We here discuss these cases highlighting the importance of expert pathological review, utilizing molecular testing to identify the underlying genetic targets for personalized therapy, and the potential role of PD-1 inhibitors for the treatment of ATC.

Importance: Human papillomavirus-associated (HPV+) oropharyngeal squamous cell carcinoma (OPSCC) is a distinct form of head and neck squamous cell carcinoma (HNSCC) with its own American Joint Committee on Cancer staging system. However, pathologic risk stratification for HPV+ OPSCC largely remains based on the experience with HPV-unassociated HNSCC. Objective: To compare the survival discrimination of traditional pathologic risk stratification for both HPV+ OPSCC and HPV-unassociated HNSCC and derive a novel pathologic risk stratification system for HPV+ OPSCC with improved survival discrimination. Design, Setting, and Participants: In this retrospective cohort study, we used the National Cancer Database to identify 15â¯324 patients diagnosed with nonmetastatic HNSCC between January 1, 2010, and December 31, 2013, who were treated with upfront surgery and neck dissection. We compared traditional pathologic risk stratification for HPV+ OPSCC and HPV-unassociated HNSCC and then derived a novel pathologic risk stratification system. Analyses were performed from July 1, 2018, to January 31, 2019. Exposures: Definitive primary surgical resection and neck dissection. Main Outcomes and Measures: Survival discrimination of pathologic risk stratification systems measured with concordance indices. Results: This retrospective cohort study included 15â¯324 patients (10â¯779 men and 4545 women; mean [SD] age, 59.9 [11.8] years) with surgically treated nonmetastatic HNSCC. Separation of survival curves for HPV-unassociated HNSCC using traditional pathologic risk stratification (5-year overall survival for the low-, intermediate-, and high-risk groups) were 76.2%, 54.5%, and 40.9%, respectively. Separation curves for HPV+ OPSCC were 93.2%, 88.9%, and 83.7%, respectively. Human papillomavirus-unassociated HNSCC had a concordance index of 0.68, whereas HPV+ OPSCC had a concordance index of 0.58. A novel risk stratification system for HPV+ OPSCC that more closely fits actual survival rates for HPV+ OPSCC was derived. The system incorporated the composite number of pathologic adverse features. This composite risk stratification system was associated with an improved concordance index of 0.67 for HPV+ OPSCC. Adjuvant treatment with radiation was not associated with improved survival for patients categorized as low risk according to the new risk stratification system, but this treatment was associated with improved survival for patients in the intermediate- and high-risk groups. Conclusions and Relevance: Traditional pathologic risk stratification shows poor survival discrimination for HPV+ OPSCC and classifies many patients with an excellent prognosis as high risk. We derived a novel composite pathologic risk stratification system for HPV+ OPSCC that may be associated with improved survival discrimination.

OBJECTIVE: The submandibular gland (SMG) is typically included in level I neck dissection specimens despite limited data demonstrating SMG invasion. The main objective of this article is to determine the rate and pathways of SMG invasion by squamous cell carcinoma of the oral cavity and oropharynx. DATA SOURCES: A systematic review of relevant studies was performed, evaluating articles identified via the PubMed, Cochrane, and Medline databases. REVIEW METHODS: Descriptive features of primary tumors, primary treatment modalities, the rate and pathway of SMG invasion, and survival outcomes, if present, were reported following the PRISMA guidelines. RESULTS: The initial literature search yielded 273 articles, of which 17 met inclusion criteria. A total of 2306 patients with 2792 SMG resections were analyzed. Fifty-eight resections (2.0%) were revealed to have tumor involvement. Among patients with SMG tumor involvement, the most common invasion pathway was direct SMG invasion by primary tumor (43 of 58, 74.1%). The second-most common mode of SMG invasion was from involved adjacent lymph nodes (10 of 58, 17.2%). Only 3 SMG resections out of 2792 (0.1%) had isolated metastatic parenchyma without evidence of direct tumor invasion or invasion by involved lymph nodes. CONCLUSION: Given this rarity of SMG involvement, preservation of SMG might be feasible in selected patient population. However, additional studies need to examine the functionality of preserved SMGs among patients who receive postoperative adjuvant radiation therapy.

OBJECTIVE: To evaluate the association between findings of blinded reviews of preoperative drug-induced sleep endoscopy (DISE) examinations using the VOTE Classification and obstructive sleep apnea (OSA) surgical outcomes in a large multicenter, international cohort. METHODS: Retrospective, multi-center cohort study of adults without tonsillar hypertrophy who underwent pharyngeal surgery for OSA. The study included only participants without enlarged tonsils. Four independent reviewers performed blinded review of preoperative DISE videos using the VOTE Classification system and scoring of a primary structure contributing to airway obstruction. DISE findings were examined for an association with surgical outcomes with univariate analyses and multiple regression. RESULTS: Two hundred seventy-five study participants were included from 14 centers. Mean age was 51.4 ± 11.8 years, and body mass index was 30.1 ± 5.2 kg/m2 . There was moderate interrater reliability (kappa = 0.40-0.60) for DISE findings. Oropharyngeal lateral wall-related obstruction was associated with poorer surgical outcomes (adjusted odds ratio (AOR) 0.51; 95% CI 0.27, 0.93). Complete tongue-related obstruction was associated with a lower odds of surgical response in moderate to severe OSA (AOR 0.52; 95% CI 0.28, 0.98), with findings that were similar but not statistically significant in other analyses. Surgical outcomes were not clearly associated with the degree and configuration of velum-related obstruction or the degree of epiglottis-related obstruction. Surgical response was associated with tonsil size and body mass index (inversely). CONCLUSION: DISE findings concerning the oropharyngeal lateral walls and tongue may be the most important findings of this evaluation technique. LEVEL OF EVIDENCE: 2B Laryngoscope, 129:761-770, 2019.

OBJECTIVE: To perform an evidence-based review with recommendations that evaluates the indications and utility of negative pressure wound therapy (NPWT) in the head and neck. METHODS: The authors searched the PubMed, Medline, Embase, Web of Science, and Cochrane Library databases for relevant literature. The primary outcome was successful intended use of NPWT, be it for granulation tissue formation, infection control, or complete wound closure. Patient demographics, etiology, and other clinical characteristics were explored. Meta-analysis of observational studies was used to examine response rates and wound sizes. RESULTS: Fifty-seven articles encompassing 522 patients were included. The most common etiologies reported included: neoplasm (343 patients [65.7%]), oro-/pharyngocutaneous fistula (9.8%), infection (10.5%), and trauma (9.6%). The majority of wounds treated were in the neck (61.6%). Potential risk factors that may compromise wound healing were noted in 217 of 522 patients (41.6%). Of these 217 patients, 135 had properly documented risk factors, with the most common being prior irradiation (63%). The overall mean response across studies was 85.7% (95% confidence interval: 0.806-0.896, P < 0.001, I2 = 0 %). CONCLUSION: Negative pressure wound therapy is useful for the management of head and neck wounds and should be considered for patients in whom wound healing is progressing insufficiently, including those with a history of head and neck cancer, oro-/pharyngocutaenous fistula, and trauma. Randomized controlled trials further comparing NPWT versus other modalities may be invaluable in further delineating its appropriate role. Laryngoscope, 129:671-683, 2019.
