The internal mammary artery perforator flap in pharyngoesophageal, cervical tracheal, and cutaneous neck reconstruction.

The internal mammary artery perforator (IMAP) flap is an evolution of the deltopectoral flap that is harvested based upon a single perforator from the internal mammary artery. Its favorable characteristics include pliability as a fasciocutaneous flap, ease of harvest, and minimal donor site morbidity. In this paper, we report our harvest technique and the versatility of the IMAP flap for pharyngoesophageal, cervical tracheal, and cutaneous neck defects. We seek to highlight the IMAP as a useful regional reconstructive option in both the primary and salvage reconstructive setting. As such, this flap is an important option in the head and neck reconstructive surgeon's armamentarium.

Surgical clinical trials for HPV-positive oropharyngeal carcinoma.

The treatment of HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) continues to evolve as multiple ongoing and recently completed clinical trials investigate the role of surgery, radiation therapy, chemotherapy, and immunotherapy. Current trials are investigating transoral robotic surgery (TORS) in treatment de-escalation protocols in an effort to optimize quality of life, while maintaining historical survival rates. The advantage of TORS is its minimally invasive approach to primary resection of the tumor as well as valuable pathologic staging. The ORATOR trial reported poorer quality of life in patients treated with TORS compared to primary radiotherapy though this was not a clinically meaningful difference. The recently published ECOG 3311 trial showed that surgery can be used to safely de-escalate the adjuvant radiation dose to 50 Gy in intermediate-risk patients. In this review, we summarize and discuss the past and current clinical trials involving surgery in the treatment of HPV-positive OPSCC.

Multimodal Virtual 3D Representation of a Giant Cell Tumor of the Thyroid Cartilage.

Virtual three-dimensional (3D) scanning of pathologic specimens may allow for improved communication between the surgeon and pathologist, as well as enhanced patient counseling and engagement. We report the rare case of a giant cell tumor of the thyroid cartilage and present a multimodal 3D representation. Preoperative 3D printing of the anatomic structures from cross-sectional imaging, as well as novel ex vivo 3D scanning of the fresh pathologic specimen for virtual 3D specimen mapping, was performed.

Transcervical arterial ligation for prevention of postoperative hemorrhage in transoral oropharyngectomy: Systematic review and meta-analysis.

BACKGROUND: Transcervical arterial ligation has been studied as a useful procedure to prevent bleeding events after transoral robotic surgery (TORS). METHODS: A systematic review of English-language literature on arterial ligation in TORS from 2005 to 2019 was conducted using Cochrane, PubMed, Web of Science (WoS), and ScienceDirect databases. Studies evaluating ligation and rates of postoperative hemorrhage were included. Meta-analysis of included studies was performed to assess impact of ligation on postoperative hemorrhage. RESULTS: Five studies with 2008 patients were included. History of radiation (odds ratio [OR] = 2.26, P = .02) and advanced tumor stage (OR = 1.93, P = .02) were found to predispose patients to postoperative hemorrhage. Arterial ligation was protective against severe hemorrhage in the mixed primary surgical modality cohort (OR = 0.33, P = .03) and in the TORS-only subgroup (OR = 0.21, P = .02), but did not significantly impact overall odds of postoperative hemorrhage. CONCLUSION: Transcervical arterial ligation offers protection against major/severe postoperative hemorrhage in patients undergoing TORS. LEVEL OF EVIDENCE: II.

Occult Metastasis in Laryngeal Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis.

OBJECTIVE: The incidence of occult metastasis (OM) in laryngeal squamous cell carcinoma (SCC) is still widely debated. In this systematic review, we aim to determine the rate of OM in laryngeal SCC, its impact on recurrence, and the role of elective neck dissection (END) in the management of the clinically negative neck. METHODS: A systematic review of the English-language literature in Web of Science, PubMed, MEDLINE, and Cochrane Library databases on occult metastasis in laryngeal SCC from 1977 to 2018 was conducted. Studies evaluating occult metastasis (OM) in patients with laryngeal SCC with clinically negative necks undergoing surgery were included. Studies evaluating other head and neck subsites, clinically node positive, and salvage patients were excluded. RESULTS: Twenty-one articles with a total of 5630 patients were included. The overall rate of OM was 20.5% and was 23% and 12.2% in supraglottic and glottic tumors, respectively. The OM rate in T1-T2 tumors was 13% and 25% in T3-T4 tumors. T3-T4 tumors had significantly greater odds of developing OM compared to T1-T2 tumors (Odds Ratio [OR] = 2.61, 95% Confidence Interval [CI] = 1.92-3.55, P < .00001). Patients with OM were more likely to develop distant metastasis (OR = 5.65, 95% CI = 3.36-9.51, P < .00001). CONCLUSIONS: Patients with advanced T-stage laryngeal SCC should undergo elective neck treatment. More aggressive treatment for patients with history of OM should be considered due to the risk of subsequent regional and distant metastasis. LEVEL OF EVIDENCE: II.

Symptoms and Clinical Findings in Primary Headache Syndrome Versus Chronic Rhinosinusitis.

BACKGROUND: Primary headache syndrome (PHS) patients frequently present to otolaryngologists with sinonasal complaints and diagnosis of chronic rhinosinusitis (CRS) due to symptomatic overlap. In this study, we compare demographic, subjective, and objective clinical findings of patients with PHS versus CRS. METHODS: We retrospectively reviewed a database of patients presenting to a single tertiary care Rhinology clinic from December 2011-July 2017. Sino-Nasal Outcome Test-22 (SNOT) scores and Lund-Kennedy endoscopy scores were obtained. Lund-MacKay CT scores were calculated, if available. Requirement of headache specialist management was compared between PHS and CRS groups. Patients with both CRS and PHS (CRScPHS) that required headache specialist management were compared to patients with CRS without PHS (CRSsPHS) and patients with PHS alone using Kruskal-Wallis analysis of variance. Receiver operating characteristic (ROC) analyses were carried out to determine significant diagnostic thresholds. RESULTS: One-hundred four PHS patients and 130 CRS patients were included. PHS patients (72.1%) were more likely than CRS patients to require headache specialist management (6.9%, p<0.0001). CRSsPHS patients had significantly higher Nasal domain scores compared to PHS patients (p = 0.042) but not compared to CRScPHS patients (p>0.99). CRScPHS (p = 0.0003) and PHS (p<0.0001) subgroups of patients had significantly higher Aural/Facial domain scores compared to CRSsPHS patients. PHS patients also had significantly higher Sleep domains scores compared to CRSsPHS patients (p<0.0001). Both CRScPHS and CRSsPHS subgroups had significantly higher nasal endoscopy scores (p<0.0001) and CT scores (p = 0.04 & p<0.0001, respectively) compared to the PHS group. Aural/Facial domain score of 4, nasal endoscopy score of 4, and CT score of 2 were found to be reliable diagnostic thresholds for absence of CRS. CONCLUSIONS: The SNOT-22 may be used to distinguish PHS from CRS based upon the Aural/Facial and Sleep domains. Patients with CRS have more severe Nasal domain scores and worse objective endoscopy and CT findings.

Cost comparison between surgical and conservative management for pediatric sinogenic subperiosteal abscesses.

BACKGROUND: There remains variation in management of orbital complications of acute bacterial rhinosinusitis (ABRS); specifically, those subperiosteal abscesses that present without immediate surgical indication. Recent systematic reviews on management and proposed treatment algorithms are helpful but do not consider the financial implications for healthcare systems and patients. METHODS: A retrospective chart review of pediatric patients from a tertiary care children's hospital between 2002 and 2020 was performed, identifying patients via ICD coding corresponding to acute bacterial sinusitis and orbital involvement classified as Chandler 3 confirmed by contrasted computed tomography (CT). Two groups of patients were identified: intravenous (IV) antibiotics alone and IV antibiotics plus surgery. Billing records of total hospital charges and physician fees were recorded for financial analysis. Demographic, length of stay, and charges were analyzed. RESULTS: 58 patients with ABRS and Chandler 3 orbital involvement were confirmed by CT imaging. Twenty-nine (50%) were treated with IV antibiotics alone, and twenty-nine (50%) underwent surgery in addition to IV antibiotics. There were no significant differences in patient demographics. The average total hospital charges for the medically managed group were $9262 ± 4831 compared to $30,830 ± 11,397 for the surgical group (p < 0.0001). In the medically managed group, the average hospital fees were $7305 ± 4048 and the average physician fees were $1543 ± 799. In the surgical group, the average hospital and physician fees were also significantly higher at $23,071 ± 7305 (p < 0.0001) and $7763 ± 3335 (p < 0.0001), respectively. Patients who were treated medically and had a longer than average LOS still had significantly fewer charges than those treated with antibiotics plus surgery and a shorter than average length of stay [$15,311 and $27,723, respectively (p = 0.02)]. CONCLUSION: Pediatric ABRS with orbital involvement requires prompt attention and management. Controversy persists over subperiosteal abscess management that present without overt surgical indications. Surgical intervention is expensive. Our subgroup analysis demonstrates the magnitude of this cost difference. Specifically, longer inpatient stays with IV antibiotics alone appear to be significantly cheaper than shorter ones that include surgery. Not all Chandler 3 patients are candidates for non-surgical management; however, clinicians are encouraged to keep these data in mind for those patients where further medical management is safe and may yield less expensive clinical resolution.

Use of mucosal eosinophil count as a guide in the management of chronic rhinosinusitis.

BACKGROUND: Chronic rhinosinusitis (CRS) is a local inflammatory process driven by eosinophils. Mucosal eosinophil count (MEC) has previously been demonstrated to be a reliable indicator of disease severity. We aim to evaluate use of MEC in guiding medical management of CRS after functional endoscopic sinus surgery (FESS). METHODS: We retrospectively reviewed patients with CRS who underwent FESS from 2004 to 2017. Tissue MEC per high-power field (HPF) was determined by pathologic examination. MECs were compared by polyp status, postoperative medication requirements, and revision surgery. Patients received normal saline (NS) nasal irrigations with additional treatment as needed for disease control: 1-drug therapy (1-DT) intranasal steroid spray (ISS), 2-drug therapy (2-DT) ISS plus budesonide nasal irrigations (BNI) or leukotriene receptor antagonist (LRA), or 3-drug therapy (3-DT) ISS plus BNI and LRA. Correlations between MEC and 22-item Sino-Nasal Outcome Test (SNOT-22), preoperative computed tomography (CT), and nasal endoscopy scores were evaluated. RESULTS: A total of 156 patients were included. Fifty-seven were managed with 1-DT, 35 with 2-DT, and 62 with 3-DT. Across all patients, mean postoperative 6-month and 1-year SNOT-22 (18.1 ± 17.0, 18.1 ± 20.2, respectively) and nasal endoscopy (3.6 ± 3.8, 3.6 ± 4.1, respectively) scores were significantly lower than preoperative scores (37.4 ± 22.8, 6.5 ± 4, respectively). With increasing MEC, odds of requiring 2-DT (odds ratio [OR] = 1.1, p = 0.0002), 3-DT (OR = 1.12, p < 0.0001), and revision surgery (OR = 1.11, p < 0.0001) were significantly increased. Preoperative endoscopy (ρ = 0.44, p < 0.0001) and CT scores (ρ = 0.51, p < 0.0001) and postoperative 6-month (ρ = 0.55, p < 0.0001) and 1-year (ρ = 0.4, p < 0.0001) endoscopy scores demonstrated good correlation with MEC. CONCLUSION: MEC correlates with objective clinical disease severity and may guide aggressiveness of management for the individual patient.

Preoperative Stellate Ganglion Block for Perioperative Pain in Lateralized Head and Neck Cancer: Preliminary Results.

Patients with head and neck cancer represent a vulnerable population at particular risk of opioid dependence due to frequent histories of substance abuse, requirement of extensive surgery, and the synergistic toxicity of multimodal therapy. Regional anesthetic techniques have been used by other surgical disciplines to facilitate early recovery after surgery and decrease postoperative patient narcotic requirements. This pilot study investigates the efficacy of a preoperative regional analgesia using stellate ganglion block in lateralized head and neck cancer surgery. From our early results, stellate ganglion blockade may hold promise as an effective preoperative intervention for controlling early postoperative pain, lessening narcotic requirements, and improving quality of life.

Salivary Clear Cell Carcinoma Clinicopathologic Characteristics and Outcomes: A Population-Based Analysis.

BACKGROUND: Salivary clear cell carcinoma is an uncommon, low-grade malignancy for which limited data describing predictive clinicopathologic factors and treatment outcomes exist because of rarity. METHODS: The authors queried the Surveillance, Epidemiology, and End Results database from 1982 to 2014. Multivariate Cox and Kaplan-Meier analyses were performed to determine disease-specific survival (DSS) and predictive clinicopathologic factors. RESULTS: One hundred ninety-eight patients with salivary clear cell carcinoma were included. Overall incidence was 0.011 per 100 000 individuals, with no significant annual percentage change across years (-0.93%, P = .632). Five-, 10-, and 20-year DSS rates were 81.3% (n = 117), 69.6% (n = 94), and 55.3% (n = 68), respectively. Men (hazard ratio, 4.74; P = .0087) and patients with regional (hazard ratio, 5.59; P = .018) or distant (hazard ratio, 8.9; P = .01) metastases carried a worse prognosis. Five-year DSS was greater in patients with localized disease (96.36%, P < .0001) than those with regional or distant metastases. Treatment with surgery alone had better 10-year DSS (86.3%) compared with treatment with combination radiation and surgery (57.6%) or radiation monotherapy (18.75%, P < .0001). CONCLUSIONS: Salivary clear cell carcinoma carries an overall good prognosis. Patients with localized disease and those treated with surgery alone have more favorable prognoses. Male patients and those with regional or distant metastatic disease at time of presentation carry a worse prognosis. LEVEL OF EVIDENCE: N/A.

Workup of Suspected Chest Metastases on 18F-FDG-PET/CT in Head and Neck Cancer: Worth the Wait?

The objective of our study is to assess the impact of equivocal or positive positron emission tomography combined with low-dose noncontrast computed tomography (PET/CT) findings in the chest on treatment for head and neck cancer (HNC). We reviewed charts of patients presented at Augusta University's Head and Neck Tumor Board (AUTB) between 2013 and 2016 with the following exclusion criteria: <18 years, Veterans Affairs patients, those with incomplete data, and those without a history of head and neck squamous cell carcinoma. The lung/thorax sections of the radiologists' PET/CT reports were graded as "Positive, Equivocal, or Negative" for chest metastases. Patients who underwent workup for suspected chest metastases were assessed for treatment delays, changes in treatment plans, and complications. In addition, we evaluated the time between AUTB presentation and peri-treatment PET/CT to primary treatment initiation were calculated between groups. There was a total of 363 patients with PET/CT prior to treatment, the read was "Negative" in 71.3% (n = 259), "Equivocal" in 20.9% (n = 76), and "Positive" in 5.8% (n = 21). Of 272 patients with complete treatment data, 22 underwent workup for suspected chest metastases. Mean time from PET/CT to treatment initiation was 27.5 days without workup and 64.9 days with workup ( P < .0001), and from AUTB presentation was 29.1 days without workup and 62.5 days with workup ( P < .0001). Five (19.2%) patients experienced a complication from workup. Twenty (76.9%) patients had no changes in their treatment plan after workup. In conclusion, our results for potential chest metastases on PET/CT in patients with HNC are often not clear-cut. Workup of suspected chest metastasis based on PET/CT findings significantly delays primary treatment initiation and may cause serious complications.

Cervical nodal metastasis after malignant conversion of sinonasal inverted papilloma: Report of a rare case and literature review.

Malignant conversion of sinonasal inverted papilloma (SNIP) occurs in approximately ten percent of cases. These tumors are classically described as locally destructive, but without metastatic potential. Only four cases of malignant conversion with cervical nodal metastases have been described in the English literature. We present the rare case of a 61-year-old Caucasian male with a nasopharyngeal recurrence of malignant SNIP with cervical and retropharyngeal nodal metastases. The patient underwent endoscopic transpterygoid with nasoseptal flap reconstruction, followed by staged bilateral and retropharyngeal node dissection. Histopathology of the specimens demonstrated poorly differentiated invasive nonkeratinizing squamous cell carcinoma with inverted-type features. Three months after surgery, the patient suffered from C1-C2 fractures consistent with osteoradionecrosis and expired. Although the rate of malignant conversion of SNIP is low, this case highlights the need for aggressive, definitive treatment and surveillance.

Reliability of the supraorbital ethmoid cell vs Keros classification in predicting the course of the anterior ethmoid artery.

BACKGROUND: We previously showed that the supraorbital ethmoid cell (SOEC) is a reliable landmark for identifying the anterior ethmoid artery (AEA). Recent data have suggested that Keros classification is also a dependable predictor. We aim to characterize the location of the AEA and its relation to the skull base in patients with and without SOEC using the Keros classification. METHODS: Retrospective radiographic evaluation of computed tomography (CT) scans of 76 patients (40 with SOEC, 36 without) was conducted. Distance of AEA from skull base and prevalence of AEA outside of the skull base were measured on each side and compared between groups using the 2-sample t test and χ2 test, respectively. Subgroup analysis was carried out based on the Keros classification. RESULTS: Mean distance of AEA from the skull base was 1.32 ± 1.5 mm in patients with SOEC and 0.47 ± 1.08 mm in those without (p < 0.001). Prevalence of AEA outside of the skull base was 53.8% in those with SOEC and 18.1% in those without (p < 0.001). Comparing patients with SOEC to those without, AEA was found below the skull base in 30% vs 0% of cases with Keros type 1 (p = 0.45), 58% vs 14.5% with Keros type 2 (p < 0.001), and 60% vs 50% with Keros type 3 (p = 0.72). CONCLUSION: The presence of SOEC is associated with a higher prevalence of the AEA coursing below the level of the skull base in all Keros types, thus placing the artery at greater risk for injury. Careful surgical planning is needed to avoid potential orbital complications.

In vitro analysis of growth patterns of invasive fungal species on commonly used endonasal hemostatic agents.

OBJECTIVE: Previous studies have not examined the potential role of endonasal hemostatic agents in facilitating growth of fungal species. We aim to determine the possibility of these to serve as a nutrient source for fungal growth. METHODS: Cultures of Aspergillus, Fusarium, and Mucor were harvested and placed in solution in sterile saline at standardized high and low concentrations. Thrombin gelatin matrix, carboxyl methylcelluose, and potato starch derivative agents were prepared following manufacturer instructions and applied to two separate Petri dishes per agent. Each substrate was then inoculated with either high or low concentrations of fungal species. Negative and positive control plates with each organism were included. Dishes were sealed, incubated, and examined daily for fourteen days for microscopic and macroscopic growth. RESULTS: Thrombin gelatin matrix was relatively resilient to growth, although Fusarium growth was noted on all packing material by day three. Carboxyl methylcellulose also supported growth of high-concentration Mucor appreciated on day five. The potato starch derivative supported fulminant growth of all fungal species. CONCLUSIONS: Endonasal hemostatic agents may be nutrient sources that facilitate growth of fungal species. This may be a consideration in a surgeon's decision to use a hemostatic agent. Prompt initial post-operative debridement may be warranted in select patients. Our findings serve as a model for further testing of fungal growth on other hemostatic materials. Future studies are needed to confirm the clinical significance of these findings in vivo.

Peri-implant bony overgrowth as a cause of revision surgery in auditory osseointegrated implantation.

Implantation of auditory osseointegrated implants, also known as bone-anchored hearing systems (BAHS), represents a surgical option for select pediatric patients aged 5 years or older with hearing loss. Functional indications in this patient population include conductive or mixed hearing loss. Common complications of implantation include skin infections, chronic skin irritation, hypertrophic skin overgrowth, and loose abutments. In a case series of 15 pediatric patients, we discovered an unexpectedly high skin-related complication rate requiring surgical revision of 53%. During revision surgery, we discovered 5 patients who exhibited significant bony overgrowth at the abutment site, a complication infrequently noted in past literature.
