RESUMO

OBJECTIVE: To characterize and compare microbiological profiles in tympanostomy tube otorrhea for children with and without cleft palate. DESIGN: Retrospective cohort study. SETTING: Pediatric otolaryngology and multidisciplinary cleft/craniofacial clinic at a single tertiary care center. PATIENTS: Children with and without cleft palate <18 years of age who underwent tympanostomy tube placement between 2017-2021. MAIN OUTCOME MEASURES: Otopathogen profiles and antibiotic resistance patterns in ear culture specimens obtained in children presenting for treatment of recalcitrant post-tympanostomy tube otorrhea. RESULTS: Of the 886 children with tympanostomy tubes placed between 2017-2021, 345 (38.9%) had clinically significant otorrhea defined as requiring at least one otolaryngology visit for treatment. Children with cleft palate had higher rates of otorrhea (50.0% versus 35.7%; P < .01). In the 128 cultures obtained, Staphylococcus aureus was the most common organism in both groups present in 39.8% of cultures; 49% were methicillin-resistant (MRSA). Pseudomonas aeruginosa was also frequently isolated (20.0% versus 23.4%, P = .69) in children with and without cleft palate. Collectively, fluoroquinolone resistance was observed in 68.6% and 27.6% of the S. aureus and P. aeruginosa isolates, respectively, however, no differences in fluoroquinolone resistance were observed between cleft and non-cleft cohorts. Corynebacterium species were isolated more frequently in children with cleft palate (26.7% versus 6.1%, P < .01), a finding of unclear significance. CONCLUSIONS: Recalcitrant post-tympanostomy tube otorrhea is more common in children with cleft palate. MRSA was the most common isolate, which was commonly resistant to first-line fluoroquinolone therapy.

RESUMO

Though specific growth rate (SGR) has potential prognostic value for oropharyngeal squamous cell carcinoma (OPSCC), there is sparse literature defining these rates. Our aims were to establish the SGRs of primary tumors (PTs) and lymph nodes (LNs) in OPSCC and to correlate SGR with oncologic outcome. A pilot study was designed with a retrospective analysis examining 54 patients from the University of California, Davis with OPSCC (diagnosed 2012-2019). Radiation oncology software and pretreatment serial CT scans were used to measure PT and LN volumes to calculate SGR and doubling time (DT). The mean PT-SGR was 1.2 ± 2.2%/day and the mean LN-SGR was 1.6 ± 1.9%/day. There was no statistically significant difference between slow-growing and fast-growing cohorts in terms of age, gender, smoking status, tumor subsite, HPV status (as determined with p16 staining), initial volume, or overall stage. SGR had no impact on 2-year overall survival, disease-free survival, or disease-specific survival. We found the average daily growth rates for OPSCC to be 1.2%/day and 1.6%/day. Our findings suggest PT- and LN-SGR are independent factors, not heavily influenced by known biomarkers and patient characteristics, without a statistical impact on prognosis. This information has value in patient counseling regarding tumor growth and in providing patients worried about fast-growing tumors the appropriate reassurance.

RESUMO

OBJECTIVE: To identify patient factors in older patients associated with making posttreatment visits in the first year after major head and neck oncologic surgery. STUDY DESIGN: Retrospective cohort study. SETTING: Academic institution. METHODS: Patients aged ≥60 years who underwent a neck dissection with or without a free flap reconstruction were retrospectively analyzed. Data collected included patient demographics, comorbidities, social variables, perioperative course, and clinical visits. RESULTS: Within a 1-year postoperative period, the 181 patients in our cohort had a mean ± SD 6.37 ± 3.6 postoperative clinic visits; 70% attended at least 4 visits. Multivariable regression analysis showed a significant association with distance closer to the hospital (P = .013): for every 10-mile increase in distance, the number of visits decreased by 0.15 (SE = 0.06). Additionally, receiving adjuvant radiation therapy (P = .0096) demonstrated significant associations: when compared with no adjuvant therapy, radiation therapy had on average 1.5 (SE = 0.56) more visits, and chemoradiation had 0.04 (SE = 0.73) more visits. CONCLUSION: Older patients who undergo major head and neck oncology surgery are more likely to attend posttreatment visits in the 1 year following surgery if they are discharged home rather than to a skilled nursing facility, live closer to the hospital, and undergo adjuvant radiation therapy.

RESUMO

OBJECTIVE: To determine the accuracy of the Pediatric Sleep Questionnaire (PSQ) as a screening tool for obstructive sleep apnea in children with craniofacial anomalies. DESIGN: Retrospective cohort study. SETTING: Multidisciplinary cleft and craniofacial clinic at a tertiary care center. PATIENTS: Children with craniofacial anomalies 2 to ≤18 years of age who both completed a PSQ screen and underwent polysomnography (PSG) without interval surgery. MAIN OUTCOME MEASURES: Sensitivity and specificity of the PSQ in detecting an obstructive apnea-hypopnea index (AHI) ≥ 5 events/hour. RESULTS: Fifty children met study criteria, with 66% (n = 33) having an associated syndrome. Mean patient age at time of PSQ was 9.6 + 4.0 years. Overall, 33 (64%) screened positive on the PSQ, while 20 (40%) had an AHI ≥ 5. The sensitivity and specificity for identifying AHI ≥ 5 was 70% and 40%, respectively. With subgroup analysis, the sensitivity and specificity were higher (100% and 50%) in children with non-syndromic palatal clefting but lower (65% and 31%) in children with a syndrome or chromosomal anomaly. There was no correlation detected between PSQ score and AHI severity (p = 0.25). The mean obstructive AHI in the study population was 10.1 ± 22.7 despite 44% (n = 22) undergoing prior adenotonsillectomy. CONCLUSIONS: The PSQ was less sensitive and specific in detecting an AHI ≥ 5 in children with craniofacial anomalies than in a general population, and particularly poor in for children with syndrome-associated craniofacial conditions. Given the high prevalence of OSA in this patient population, a craniofacial-specific validated screening tool would be beneficial.

RESUMO

PURPOSE: The purpose of this study is to characterize deficits in olfactory-specific and sinonasal-specific QoL after total laryngectomy (TL) with validated patient reported outcome measures. METHODS: Thirty patients who had a TL were prospectively enrolled. Patient demographics, as well as scores from the Questionnaire of Olfactory Disorders Negative Statements (QOD-NS) and the Sino-nasal Outcome Test-22 (SNOT-22) were collected. Univariate analysis was performed to assess associations between patient characteristics and QoL scores. RESULTS: The average QOD-NS score was 37.9 ± 11.4 (<38.5 is considered abnormal) and average SNOT-22 score was 32.0 ± 3.8 (>20 indicates a moderate/severe impact on QoL). The abnormal QOD-NS group had a greater percentage of former smokers compared to the normal group (77.8% vs. 58.1%; P = 0.56) and more median days from surgery compared to the normal group (904 vs. 477 days; P = 0.24). CONCLUSIONS: Olfactory dysfunction associated with TL results in blunting of olfactory-specific QoL.

RESUMO

OPINION STATEMENT: As the field of oncology enters the era of precision medicine and targeted therapies, we have come to realize that there may be no single "magic bullet" for patients with head and neck cancer. While immune check point inhibitors and some targeted therapeutics have shown great promise in improving oncologic outcomes, the current standard of care in most patients with head and neck squamous cell carcinoma (HNSCC) remains a combination of surgery, radiation, and/or cytotoxic chemotherapy. Nevertheless, advances in precision medicine, next-generation sequencing (NGS), and targeted therapies have a potential future in the treatment of HNSCC. These roles include increased patient treatment stratification based on predictive biomarkers or targetable mutations and novel combinatorial regimens with existing HNSCC treatments. There remain challenges to precision medicine and NGS in HNSCC, including intertumor and intratumor heterogeneity, challenging targets, and need for further trials validating the utility of NGS and precision medicine. Additionally, there is a need for evidence-based practice guidelines to assist clinicians on how to appropriately incorporate NGS in care for HNSCC. In this review, we describe the current state of precision medicine and NGS in HNSCC and opportunities for future advances in this challenging but important field.

RESUMO

OBJECTIVE: To investigate a possible link between breast and thyroid cancer. METHODS: A multicenter retrospective review of patients in the electronic medical records of six Accrual to Clinical Trial (ACT) institutions with both breast cancer and thyroid carcinoma. Each center queried its data using a predefined data dictionary. Information on thyroid and breast cancer included dates of diagnosis, histology, and patient demographics. RESULTS: A random-effects model was used. There were 4.24 million women's records screened, 44 605 with breast cancer and 11 846 with thyroid cancer. The relative risks observed at each institution ranged from 0.49 to 13.47. The combined risk ratio (RR) estimate was 1.77 (95% confidence interval: 0.50-5.18). CONCLUSION: There was no association between the risk of developing thyroid cancer and being a breast cancer survivor compared to no history of breast cancer, but the range of relative risks among the participating institutions was wide. Our findings warrant further study of more institutions with larger sample size. Additionally, further analysis of the significance of regional RR differences may be enlightening.

RESUMO

OBJECTIVES: Head and neck cancer surgeons frequently interact with dying patients with advanced disease and their families, but little is known about their bereavement practices after a patient's death. The aim of this study is to elucidate the frequency of common bereavement practices, cited barriers to bereavement, and predictive physician factors that lead to an increase in bereavement practices among head and neck cancer surgeons. METHODS: A 20-item survey was sent to 827 active surgeons of the American Head and Neck Society. Approval was obtained and the survey was distributed through the American Head and Neck Society. Demographics, frequency of common bereavement practices, empathy, and barriers were assessed. Multiple linear regression was performed to determine physician factors associated with more frequent bereavement follow-up. RESULTS: There were 156 respondents (18.9% response rate). Overall, surgeons were more likely to usually/always call (48.5%) or send a letter (42.4%) compared with other practices such as attending funerals (0%), offering family meetings (18.6%), or referring family members to counseling (7.7%). Many barriers were cited as being at least somewhat important: being unaware about a patient's death (67.3%) was the most cited, whereas 51.3% cited a lack of mentorship/training in this area. Scoring higher on empathy questions (P ≤ .001) was associated with more frequent surgeon bereavement follow-up with the family of deceased patients. CONCLUSION: There is substantial practice variation among surgeons suggesting a lack of consensus on their roles in bereavement follow-up. Having higher empathy was predictive of higher engagement. LEVEL OF EVIDENCE: NA Laryngoscope, 132:1971-1975, 2022.

RESUMO

Otolaryngology is a small and highly sought-after surgical subspecialty with sparse residency positions, making it competitive to match into. Allopathic (MD) students without home otolaryngology residency programs, osteopathic (DO) medical students, and underrepresented minorities have historically faced additional challenges in matching into otolaryngology. These specific populations generally experience limited opportunities in establishing mentors, engaging in scholarly activity, and gaining early exposure to clinical settings. Even though the American Osteopathic Association and the Accreditation Council for Graduate Medical Education merger was in part established to create equity among applicants, there remains a substantial disparity among the match rates of medical students of various educational and cultural backgrounds. The National Otolaryngology Interest Group is a student-led interest group created to provide all medical students, especially those facing barriers, with the resources needed to best prepare for matching into an otolaryngology residency program and ultimately a career in otolaryngology.

RESUMO

OBJECTIVE: Applicant demographics during the 2019-2020 residency cycle were evaluated to determine if strict utilization of United States Medical Licensing Examination (USMLE) scores in applicant selection could lead to a restriction in diversity. STUDY DESIGN: Cross-sectional study. SETTING: Otolaryngology residency applicants to a single institution. METHODS: A total of 381 applicants were analyzed by age, gender, applicant type, race/ethnicity, USMLE scores, permanent zip code, and graduating medical school. RESULTS: Among applicants, 37% were women; 9% were ≥30 years of age; 12% were underrepresented minorities (URMs); 71% to 81% had above-average socioeconomic surrogate markers; 22% were from a top 25 US News & World Report-ranked institution; and 81% were from an institution with an otolaryngology residency program. There was no increase in applicants who identified as URM from the 2015-2020 cycles. Multivariable regression analysis showed that applicants who were international medical graduates, URMs, and ≥30 years of age had lower Step 1 and Step 2 scores (P < .05). Applicants who identified as women had a lower Step 1 score, and those from top 25 National Institutes of Health-funded institutions had a higher Step 1 score; however, there was no difference when Step 2 scores were compared (P > .05). CONCLUSION: Our data suggest that in the pre-USMLE Step 1 pass/fail setting, strict adherence to USMLE scores may lead to disproportionally low recruitment of applicants who are women, ≥30 years of age, URMs, and from institutions without an otolaryngology residency program. We must implement measures against overemphasizing the absolute values of USMLE scores for a true holistic review of applicants, specifically to prevent an overemphasis on the USMLE Step 2 score.

RESUMO

OBJECTIVE: We analyzed the incidence of facial nerve sacrifice during parotidectomy for metastatic cutaneous squamous cell carcinoma (CSCC). STUDY DESIGN: We retrospectively reviewed the charts of patients with cutaneous squamous cell carcinoma. SETTING: We used our CSCC institutional database, which includes patients treated at the University of California-Davis from 2001 to 2018. METHODS: We evaluated patients who presented with biopsy-proven head and neck CSCC who underwent parotidectomy as a part of surgical treatment. We assessed the frequency of facial nerve sacrifice required in patients with normal preoperative facial nerve function with metastatic disease to the parotid. We evaluated the association between sacrifice and high-risk tumor variables using multivariate analysis. RESULTS: We identified 53 patients with parotid metastasis and normal preoperative facial nerve function. Thirteen percent of patients required sacrifice of the main trunk of the facial nerve and 27% required sacrifice of a branch of the facial nerve. All patients who underwent facial nerve sacrifice had extracapsular spread (ECS). Perineural invasion (PNI) in the primary tumor (odds ratio [OR], 9.11; P = .041) and location of metastasis within the parotid body (OR, 6.6; P = .044) were independently associated with facial nerve sacrifice. CONCLUSION: Patients with regionally metastatic CSCC to the parotid gland frequently require sacrifice of all or a component of the facial nerve despite normal preoperative function. The likelihood of nerve sacrifice is highest for tumors with PNI and metastatic disease within the body of the parotid.

RESUMO

OBJECTIVES: To describe the impact that the coronavirus disease 2019 (COVID-19) pandemic had on the presentation of patients with head and neck cancer in a single tertiary care center. STUDY DESIGN: Retrospective cohort study. SETTING: Academic institution. METHODS: We performed a retrospective review of patients with newly diagnosed head and neck squamous cell carcinoma (HNSCC) who presented as new patients between September 10, 2019, and September 11, 2020. Patients presenting during the 6 months leading up to the announcement of the pandemic (pre-COVID-19 period) on March 11, 2020, were compared to those presenting during the first 6 months of the pandemic (COVID-19 period). Demographics, time to diagnosis and treatment, and tumor characteristics were analyzed. RESULTS: There were a total of 137 patients analyzed with newly diagnosed malignancies. There were 22% fewer patients evaluated during the COVID-19 timeframe. The groups were similar in demographics, duration of symptoms, time to diagnosis, time to surgery, extent of surgery, and adjuvant therapy. There was a larger proportion of tumors classified as T3/T4 (61.7%) in the COVID-19 period vs the pre-COVID-19 period (40.3%) (P = .024), as well as a larger median tumor size during the COVID-19 period (P = .0002). There were no differences between nodal disease burden (P = .48) and distant metastases (P = .42). CONCLUSION: Despite similar characteristics, time to diagnosis, and surgery, our findings suggest that there was an increase in primary tumor burden in patients with HNSCC during the early COVID-19 pandemic.

RESUMO

PURPOSE OF REVIEW: This article reviews recent literature on repair of peripheral nerve injuries in the head and neck with a focus on autografts, allografts, nerve conduits, and technical considerations. RECENT FINDINGS: Contemporary nerve grafting techniques offer the potential to improve peripheral nerve outcomes and reduce donor site morbidity. A variety of donor nerves autografts have been described that offer favorable outcomes for segmental reconstruction of facial nerve defects. Recent studies have demonstrated promising results in repair of inferior alveolar nerve injuries with human allografts. Animal models describe successful reinnervation of small defects with neural conduits. The latest data do not favor protocolled nerve graft polarity or use of a motor versus sensory donor nerves. SUMMARY: Interposition nerve grafting is the gold standard for repair of peripheral nerve injuries when a tension-free primary neurorrhaphy is not possible. Autografts are the work-horse for the majority of head and neck neural defects, however, can result in some degree of donor site morbidity. Recent developments in allografting and neural conduits have the potential to further diversify the head and neck reconstructive surgeon's armamentarium. It is unclear if nerve graft makeup or polarity affect functional outcome.

RESUMO

OBJECTIVES: To elucidate the frequency and types of pre- and post-interview communication that applicants engage with programs, to garner the perceptions of both applicants and program directors (PDs), and determine if communication influences outcomes. SUBJECTS AND METHODS: Electronic surveys were distributed to otolaryngology residency applicants, and to PDs of ACGME-accredited otolaryngology programs after the 2018 to 2019 application cycle. RESULTS: 93 of 324 applicants (28.7%) and 33 of 106 PDs (31.3%) responded. In the pre-interview period, 58.1% of applicants sent emails of interest, and 41.9% had a mentor initiate communication. In the post-interview period, the majority of applicants (82.8%) sent notes of intent to their number one choice, and 32.3% had a faculty mentor communicate this on their behalf. The majority of PDs (84.8%) were undecided or did not believe that emails of interest influence decisions to offer an interview, whereas 81.8% believed that communication initiated by an applicant's mentor has an impact on interview offers. No PD agreed that declarations of intent from applicants have an impact on their rank lists, while only 33.3% of PDs believed that a mentor communicating this for an applicant has some impact. Our statistical findings are in agreement with these perceptions as neither applicant-initiated pre-interview (P = .54), mentor-initiated pre-interview (P = .62), applicant-initiated post-interview (P = .11) nor mentor-initiated post-interview (P = .78) communications influenced the number of interviews received or ultimate match outcome. CONCLUSION: Pre- and post-interview communication practices vary widely among otolaryngology applicants. Applicant-initiated communication has no impact on outcomes, while mentor-initiated communication is perceived to have more benefit, despite not impacting interview or match outcomes in this study.

RESUMO

The escalation of the COVID-19 pandemic has affected health care at every level, including medical education. As some fourth-year medical students graduate early to join the front lines, we must now turn our attention to those trainees in their penultimate year. In this commentary, we address the unique dilemmas facing otolaryngology residency candidates for the 2020-2021 cycle, with a focus on those applicants with no institutional otolaryngology department.

RESUMO

Rhinoplasty for cleft lip nasal deformities challenges all cleft surgeons. There is great variability of phenotypical anatomy, but iatrogenic changes and scarring from the previous surgeries add another layer of complexity. Rhinoplasties on a patient with cleft lip-palate are technically and intellectually challenging to master requiring a patient-tailored approach. The shape and structure of the nose are changed to improve both function and aesthetic appearance. In the primary setting, nasoalveolar molding is a form of presurgical infant orthopaedics used for preparation before the cleft lip and nose repair. Intermediate stages should be conservative to minimize scarring, while the definitive cleft rhinoplasty utilizes cartilage grafts from septum, ear, or rib to sculpt the nose. Hereinto, we will outline the controversies, the evidence supporting certain techniques, and our preferences.

RESUMO

OBJECTIVE: Dental implant placement in scapular free flaps is challenging. This study examines the scapula with computed tomography to identify ideal locations for predictable implant placement during preoperative planning. METHODS: Sixty-eight adult patient chest CT scans (34 men, 34 women) captured for various medical indications, were analyzed for age, height, weight, and scapula length. The lateral border of the scapula was divided into six equal segments; the midpoints of each segment (labeled proximally to distally as 1M-6M) were analyzed in cross-section as potential recipient sites for 3.5 × 8 mm implants. Also, we present a case of a 77-year-old male with ameloblastoma of the mandible who underwent patient specific planning and received a scapular free flap with dental implant placement. RESULTS: There was greater bone availability in males with a mean depth of 8.3 ± 2.8 versus 5.1 ± 3.3 mm in females (p < .01). The proximal portion (1M) of the scapula in males and females had depths of 11.3 ± 1.5 and 9.5 ± 2.3 mm, respectively. Males had depths of 8.4 ± 3.0 in M3, 9.7 ± 1.7 in M4, and 8.9 ± 1.2 mm in M6. Depth of bone available for patients with heights ≥165 cm versus <165 cm had means of 10.4 ± 1.3 and 8.0 ± 1.6 mm (p < .01), respectively; but showed no significant differences between BMI (BMI <25 vs. ≥25) and bone availability (6.8 ± 1.7 vs. 6.8 ± 1.6, p = .07), or age (<55 years vs. ≥55 years) and bone availability (9.8 ± 1.6 vs. 9.8 ± 1.6, p = .11). In our case, the patient received 6 cm length of scapular bone with four 4.1 × 14 mm endosteal implants, which upon osseointegration was able to receive a fixed dental prosthesis. Three years after the initial surgery, the patient has had no difficulty with his prosthesis. CONCLUSION: In females the most proximal portion of the scapula will predictably accommodate a dental implant, while males have multiple sites including the proximal, middle, and distal portions.
