RESUMO
OBJECTIVES/HYPOTHESIS: With the increasing emphasis on developing effective telemedicine approaches in Otolaryngology, this study explored whether a single composite image stitched from a digital otoscopy video provides acceptable diagnostic information to make an accurate diagnosis, as compared with that provided by the full video. STUDY DESIGN: Diagnostic survey analysis. METHODS: Five Ear, Nose, and Throat (ENT) physicians reviewed the same set of 78 digital otoscope eardrum videos from four eardrum conditions: normal, effusion, retraction, and tympanosclerosis, along with the composite images generated by a SelectStitch method that selectively uses video frames with computer-assisted selection, as well as a Stitch method that incorporates all the video frames. Participants provided a diagnosis for each item along with a rating of diagnostic confidence. Diagnostic accuracy for each pathology of SelectStitch was compared with accuracy when reviewing the entire video clip and when reviewing the Stitch image. RESULTS: There were no significant differences in diagnostic accuracy for physicians reviewing SelectStitch images and full video clips, but both provided better diagnostic accuracy than Stitch images. The inter-reader agreement was moderate. CONCLUSIONS: Equal to using full video clips, composite images of eardrums generated by SelectStitch provided sufficient information for ENTs to make the correct diagnoses for most pathologies. These findings suggest that use of a composite eardrum image may be sufficient for telemedicine approaches to ear diagnosis, eliminating the need for storage and transmission of large video files, along with future applications for improved documentation in electronic medical record systems, patient/family counseling, and clinical training.

The objective of our study was to assess the relationship between postoperative opioid prescribing patterns and opioid consumption among patients who underwent septoplasty or rhinoplasty. A chart review of patients who underwent either septoplasty or rhinoplasty by 3 surgeons between July 2016 and June 2017 was performed, and pertinent clinical data were collected including the amount of narcotic pain medications prescribed. A telephone interview was then conducted to assess opioid usage and pain control regimen postoperatively. The number of opioid tablets prescribed and the number consumed were converted to total morphine milligram equivalent (MME) for uniform comparison. A total of 75 patients met the inclusion criteria, and 64 completed the telephone survey. Among these 64 patients, the mean (standard deviation [SD]) prescribed MME was 289.7 (101.3), and the mean (SD) consumed MME was 100.6 (109). Similarly, the mean (SD) number of opioid tablets prescribed was 42.4 (9.7), and the mean number of tablets consumed was 14.7 (16.3). Gender, procedure performed (septoplasty or rhinoplasty), use of Doyle splints, and surgeon were not associated with the amount of opioids prescribed or used. Subjective pain control was the only factor associated with an increase in opioid use (P = .0288). There was an overabundance of opioid pain medications prescribed compared to the amount consumed for pain control after septoplasty or rhinoplasty. Abuse of prescription opioids represents an important component of the nation's opioid crisis. Surgeons must be cognizant of the problem and adjust prescribing practices accordingly.

Acute infections of the middle ear are the most commonly treated childhood diseases. Because complications affect children's language learning and cognitive processes, it is essential to diagnose these diseases in a timely and accurate manner. The prevailing literature suggests that it is difficult to accurately diagnose these infections, even for experienced ear, nose, and throat (ENT) physicians. Advanced care practitioners (e.g., nurse practitioners, physician assistants) serve as first-line providers in many primary care settings and may benefit from additional guidance to appropriately determine the diagnosis and treatment of ear diseases. For this purpose, we designed a content-based image retrieval (CBIR) system (called OtoMatch) for normal, middle ear effusion, and tympanostomy tube conditions, operating on eardrum images captured with a digital otoscope. We present a method that enables the conversion of any convolutional neural network (trained for classification) into an image retrieval model. As a proof of concept, we converted a pre-trained deep learning model into an image retrieval system. We accomplished this by changing the fully connected layers into lookup tables. A database of 454 labeled eardrum images (179 normal, 179 effusion, and 96 tube cases) was used to train and test the system. On a 10-fold cross validation, the proposed method resulted in an average accuracy of 80.58% (SD 5.37%), and maximum F1 score of 0.90 while retrieving the most similar image from the database. These are promising results for the first study to demonstrate the feasibility of developing a CBIR system for eardrum images using the newly proposed methodology.

OBJECTIVE: To provide preclinical medical students early access to otolaryngologists to learn about the specialty, facilitate acquisition of clinical skills, and provide one-on-one mentorship. METHODS: Students are matched with a single otolaryngology faculty mentor from The Ohio State University/Nationwide Children's Hospital and attend 8 hours per month in the clinic or operating room, monthly lectures, and rounds, and they give a final presentation. Mentors complete performance evaluations, and surveys are administered longitudinally until Match Day. RESULTS: Thirty-five students and 17 faculty members have participated in the program since 2015. All mentors and students found the program to be a valuable experience. When compared to nonparticipating students, participants had significantly higher confidence scores for clinical performance, knowledge of anatomy, and familiarity with the department of interest. All students felt the program prepared them well for third and fourth years, and all 8 of the initial program participants successfully matched into residency with 4 entering otolaryngology. DISCUSSION: Medical students face a competitive residency application process in otolaryngology with limited exposure, which creates an opportunity for guidance in the pursuit of matching into this field. This novel preclinical mentorship program prepares students for their clinical years and residency by facilitating acquisition of various competencies. Students gain hands-on clinical exposure in a field of interest and support for navigating the application process. IMPLICATIONS FOR PRACTICE: The structure of this program can be applied to other medical schools or specialties if the individual departments contain adequate resources of teaching faculty willing to participate.

OBJECTIVE: To assess factors associated with repair of facial dog bites in the emergency department (ED) versus the operating room (OR) and to compare rates of surgical site infection and reoperation for each venue. STUDY DESIGN: Case series with chart review. SETTING: Single institution. SUBJECTS AND METHODS: All patients younger than 18 years of age who underwent surgical repair by a consulting surgical service within 24 hours of presentation for facial dog bites between 2010 and 2013 were included. Demographics, site of injury, associated evidence of complex injury, surgical site infections within 30 days, and reoperation within 2 years were compared between patients undergoing surgical repair in the ED versus the OR. RESULTS: One hundred sixty-five patients were evaluated; 75 patients underwent repair in the ED, and 90 patients were treated in the OR. Patients treated in the ED underwent surgery more promptly than patients treated in the OR (median time from arrival to procedure start 3.3 vs 6.8 hours, P < .001). Patients treated in the OR were more likely to have longer lacerations (3.0 cm vs 7.8 cm, P < .001), lacerations of the eyelid (17% vs 42%, P = .001), involvement of multiple regions of the face (11% vs 22%, P = .039), and multiple indicators of severe injury (3% vs 12%, P = .024). There were no differences in surgical site infections (1% vs 1%, P = .721) or reoperation rates (5% vs 13%, P = .071). CONCLUSIONS: Surgical management of pediatric facial dog bites may be successfully performed in both the ED and OR settings. Severity of the injury should dictate the choice for management.
RESUMO
OBJECTIVE: To assess the utility of rapid parathyroid hormone (PTH) values in predicting transient post-operative hypocalcemia in patients with unplanned parathyroidectomy during total or completion thyroidectomy. METHODS: All patients who underwent total or completion thyroidectomy between January 2010 and January 2015 were reviewed. Incidences of post-operative hypocalcemia were compared in patients with and without unplanned parathyroidectomy. Unplanned parathyroidectomy was defined as intra-operative incidental or intentional parathyroidectomy. Logistic regression assessed for predictors of hypocalcemia and optimum amount of calcium supplementation. RESULTS: Thirty-eight (13.6%) patients had evidence of incidental parathyroidectomy and 39/280 (13.9%) patients had parathyroid autotransplantation intra-operatively. Central neck dissection and malignancy were identified as risk factors for unplanned parathyroidectomy (pâ¯=â¯0.001, pâ¯=â¯0.060). Patients with unplanned parathyroidectomy were more likely to have hypocalcemia (pâ¯=â¯0.002) and hypoparathyroidism (pâ¯<â¯0.0005). PTH value was the only significant predictor of hypocalcemia in these patients. In patients with a post-operative PTH of ≤15, initial calcium supplementationâ¯≥â¯1000â¯mg decreased the risk of hypocalcemia (pâ¯<â¯0.05). CONCLUSION: Post-operative PTH value predicts hypocalcemia in patients undergoing total and completion thyroidectomy with unplanned parathyroidectomy. In patients with a post-operative PTHâ¯<â¯15, initial calcium supplementation with ≥1000â¯mg of elemental calcium is recommended.

OBJECTIVE: To test the null hypothesis that there is no difference in patient cost savings between the telemedicine and traditional face-to-face approach. The second objective was to assess the financial impact on the peripheral healthcare system, as compared with staffing a conventional clinic with "on-site" otolaryngologist. METHODS: Twenty-one patients were enrolled. To assess "patient-benefit" cost savings, a model was formulated that would utilize a certified nurse practitioner (CNP) to conduct a general otolaryngology clinic at the peripheral site, as compared with having to travel to the tertiary referral center. A "peripheral site-benefit" cost analysis was performed to assess costs of initiating and operating a telemedicine clinic at the peripheral site, compared with having an on-site otolaryngologist. RESULTS: The total patient-benefit cost savings would be $182.09 per patient per encounter and $333.22 per patient annually. The fixed cost to the peripheral site to initiate the telemedicine system was $9,895. Two hundred sixty telemedicine encounters would be needed to offset the initial cost, and 537 encounters would be needed to surpass revenue of the conventional clinic. CONCLUSION: A real-time telemedicine otolaryngology clinic provides significant cost savings for both patients and the peripheral healthcare system. This pilot study supports telemedicine as a cost-effective approach to providing general otolaryngology care to rural patients. LEVEL OF EVIDENCE: 4.
RESUMO
OBJECTIVES/HYPOTHESIS: To assess the confidence and abilities of medical students to diagnose specific types of otologic pathology, and to determine how different training experiences in medical school impact these outcomes. STUDY DESIGN: Survey analysis. METHODS: Sixty third- and fourth-year medical students completed a computerized online survey. Participants answered questions about their otoscopic training experience and confidence, and provided diagnoses for 72 digital images taken with a high-definition video otoscope that showed common otologic pathologies of the tympanic membrane and middle ear space. RESULTS: Most participants (65%) had received less exposure to otoscopic training in medical school than they expected. Confidence in diagnostic ability was low. For diagnostic ability, the mean percent correct across pathologies was 54% ± 7.7%. Medical school year (P = .006), intended specialty (P = .022), and total number of otolaryngology rotations (P = .048) were predictive of diagnostic accuracy on univariable logistic regression analyses, but medical school year (P = .039) was the only significant independent predictor in multivariable analysis. Intended specialty (P = .047) and total number of otolaryngology rotations (P = .035) were predictive of prequiz diagnostic confidence on univariable logistic regression analyses. CONCLUSIONS: Medical students were not satisfied with their exposure to otoscopic training. Intended specialty, total number of otolaryngology rotations, and year in medical school predicted diagnostic accuracy. Intended specialty and total number of otolaryngology rotations predicted diagnostic confidence. Additional studies are needed to investigate how training experiences can be improved to optimize otoscopy training during medical school. LEVEL OF EVIDENCE: NA Laryngoscope, 129:1891-1897, 2019.

INTRODUCTION: Dog bite injuries to the face are a serious, yet modifiable public health concern. This study explores the relationship between dog breed and the risk of biting and injury. The objective of this study is to determine the relative risk and severity of dog bite injuries to the face by breed. METHODS: Retrospective chart review of facial dog bite injuries presenting to the University of Virginia Health System and Nationwide Children's Hospital. Additionally, descriptive data was collected from 240 patients over the last 15 years. Bite risk by breed was assessed by a literature search from 1970 to current. A composite measure was used to determine the severity of injury, and characterize each patient into an ordinal scale of bite severity. An average of each breed bite rate within each study was calculated and combined to create an empiric bite risk by breed. Dog breeds were also further characterized morphologically. RESULTS: Bite risk by breed from the literature review and bite severity by breed from our case series were combined to create a total bite risk plot. Injuries from Pitbull's and mixed breed dogs were both more frequent and more severe. This data is well-suited for a bubble plot showing bite risk on the x-axis, bite severity on the y-axis, and size of the bubble by number of cases. This creates a "risk to own" graphic for potential dog owners. CONCLUSIONS: Breeds vary in both rates of biting and severity. The highest risk breeds had both a high rate of biting and caused significant tissue injury. Physical characteristics can also help determine risk for unknown or mixed dog breeds. Potential dog owners can utilize this data when assessing which breed to own.

OBJECTIVE: To evaluate diagnostic concordance of a synchronous telemedicine otolaryngology clinic with use of currently available technology. STUDY DESIGN: Prospective. METHODS: Patients in a rural otolaryngology clinic were enrolled in a pilot telemedicine clinic. To assess system fidelity, an on-site and remote (consulting) otolaryngologist conducted simultaneous patient evaluations using streaming telecommunication technology for all aspects of the clinical encounter, including high-definition examination and endoscopic images. Both physicians and patients were blinded and diagnoses recorded. Post-encounter physician surveys and an original patient-centered TeleENT Satisfaction Questionnaire (TESQ) were used to assess overall satisfaction. RESULTS: Twenty-one patients were enrolled consecutively. Visual technology was found acceptable in all cases, and audio technology was acceptable in 20 of 21 encounters. Patient satisfaction was 96%, and patients felt comfortable using a telemedicine system in the future. Encounters were not significantly longer than traditional encounters. Physician diagnostic agreement was found in 95% of cases, and the consulting physician indicated that all encounters provided sufficient history, examination, and high-quality images to generate an accurate diagnosis, order additional workup, and/or make an appropriate referral. CONCLUSION: A synchronous otolaryngology telemedicine clinic is comparable to a standard clinic in terms of diagnostic concordance and patient satisfaction when using streaming technology and high-definition images. Using telemedical technology may be a viable way to increase otolaryngology access in remote or underserved areas. With system validity now established, future studies will assess the feasibility of using trained on-site physician extenders (nurse practitioners or physician assistants) to conduct in-person patient encounters with remote otolaryngologist support.

Introduction With the growing popularity of telemedicine and tele-diagnostics, clinical validation of new devices is essential. This study sought to investigate whether high-definition digital still images of the eardrum provide sufficient information to make a correct diagnosis, as compared with the gold standard view provided by clinical microscopy. Methods Twelve fellowship-trained ear physicians (neurotologists) reviewed the same set of 210 digital otoscope eardrum images. Participants diagnosed each image as normal or, if abnormal, they selected from seven types of ear pathology. Diagnostic percentage correct for each pathology was compared with a gold standard of diagnosis using clinical microscopy with adjunct audiometry and/or tympanometry. Participants also rated their degree of confidence for each diagnosis. Results Overall correctness of diagnosis for ear pathologies ranged from 48.6-100%, depending on the type of pathology. Neurotologists were 72% correct in identifying eardrums as normal. Reviewers' confidence in diagnosis varied substantially among types of pathology, as well as among participants. Discussion High-definition digital still images of eardrums provided sufficient information for neurotologists to make correct diagnoses for some pathologies. However, some diagnoses, such as middle ear effusion, were more difficult to diagnose when based only on a still image. Levels of confidence of reviewers did not generally correlate with diagnostic ability.

INTRODUCTION: Dexmedetomidine is a novel pharmacologic agent that has become a frequently used adjunct during care of pediatric patients with obstructive sleep apnea (OSA) undergoing tonsillectomy. While generally safe and effective, dexmedetomidine is associated with adverse effects of hypotension and bradycardia from its central sympatholytic effects. Due to safety concerns, our institution routinely admits patients with OSA for overnight cardiorespiratory monitoring following tonsillectomy. With such monitoring, we have anecdotally noted bradycardia in our patients and sought to investigate whether this was related to the increased use of intra-operative dexmedetomidine. METHODS: We retrospectively reviewed records over an 11-month period to compare the incidence of postoperative bradycardia following hospital admission for tonsillectomy in patients who received dexmedetomidine versus those who did not. RESULTS: The study cohort included 921 patients (371 received dexmedetomidine and 550 did not). Bradycardia was asymptomatically noted in 66 patients (7.2%). No patient required medical intervention for the bradycardia or developed clinical symptoms. There was no association of bradycardia with the intra-operative administration of dexmedetomidine (8.9% of patients who received dexmetomidine vs. 9.4% who did not). In multivariable analysis, bradycardia was more common among older patients, with the administration of topical or injected lidocaine, and with specific associated procedures (inferior turbinate coblation with out-fracture or direct laryngoscopy and bronchoscopy). CONCLUSION: The increased incidence of asymptomatic bradycardia in our post-adenotonsillectomy patients seemed to relate more to increased utilization of postoperative cardiac telemetry, and did not appear associated with the use of dexmedetomidine use intra-operatively.

IMPORTANCE: Traditional facial trauma laboratories are used for teaching basic concepts of fracture reduction and hardware manipulation. Facial trauma simulation laboratories allow training physicians the opportunity to develop unique treatment plans as they would in real patient encounters. OBJECTIVE: To assess the value of a novel facial trauma simulation course requiring residents to practice advanced decision making. DESIGN, SETTING, AND PARTICIPANTS: Data were prospectively collected July 23 and August 23 and 24, 2016, in a survey study during a resident physician trauma simulation course. Fresh frozen cadaver heads were fractured using an impactor that applied a measurable amount of force. Each head was scanned with high-resolution computed tomography. Residents were paired and tasked with evaluating their specimen's imaging findings and developing a treatment plan. MAIN OUTCOMES AND MEASURES: Before the course, residents were asked their postgraduate year level, number of facial fractures treated as a resident surgeon, and their comfort level based on the Otolaryngology Milestone for Facial Trauma (OMFT; ratings range from 0-5, with 5 indicating equivalent to fellow-level experience). After the course, residents were asked to assess the course's value relative to a theoretical number of actual operative cases, and a posttraining OMFT assessment was obtained. RESULTS: Thirty resident physicians completed the course at 2 institutions. Residents represented an equivalent distribution of postgraduate year levels. The residents stated that the course was worth a mean (SD) of 6.4 (2.8) operative cases of facial trauma in terms of surgical learning. The mean change in self-reported OMFT rating after the course was 0.87 (95% CI, 0.67-1.07; P < .001, paired t test). On the basis of this change in self-perceived OMFT rating, the course was deemed to be worth 1.5 years of residency training in the management of facial fractures. CONCLUSION AND RELEVANCE: Conducting a facial trauma simulation course increases resident experience with advanced surgical decision making. LEVEL OF EVIDENCE: NA.

OBJECTIVE: To determine the clinical impact of an initiative to use ultrasound (US) as the primary diagnostic modality for children with superficial face and neck infections versus use of computed tomography (CT). METHODS: Children with a diagnosis of lymphadenitis, face or neck abscess, or face and neck cellulitis were retrospectively evaluated by the otolaryngology service. Patients were separated into two groups based on implementation of a departmental initiative to use US as the primary diagnostic modality. The pre-implementation cohort consisted of patients treated prior to the initiative (2006-2009) and the current protocol cohort consisted of patients treated after the initiative was started (2010-2013). Demographics, use of US or CT, necessity of surgical intervention, and failure of medical management were compared. RESULTS: Three hundred seventy three children were evaluated; 114 patients were included in the pre-implementation cohort and 259 patients were included in the current protocol cohort for comparison. Patients presenting during the current protocol period were more likely to undergo US (pre-implementation vs. current protocol, p-value) (12% vs. 49%, p < 0.0001) and less likely to undergo CT (66% vs. 41%, p < 0.0001) for their initial evaluation. There were no differences in the percentage of children who underwent prompt surgical drainage, prompt discharge without surgery, or trial inpatient observation. There were also no differences in the rate of treatment failure for patients undergoing prompt surgery or prompt discharge on antibiotics. For those patients who underwent repeat evaluation following trial medical management, US was used more frequently in the current protocol period (4% vs. 20%, p = 0.002) with no difference in CT use, selected treatment strategy, or treatment failure rates. CONCLUSION: Increased use of US on initial evaluation of children with superficial face and neck infections resulted in decreased CT utilization, without negatively impacting outcome. Decreasing pediatric radiation exposure and potential long-term effects is of primary importance.

BACKGROUND: Current surgical standard of care in sporadic medullary thyroid carcinoma (sMTC) consists of a minimum of total thyroidectomy with central neck dissection. Some have suggested thyroid lobectomy with isthmusectomy and central neck dissection for patients with sMTC, given their lower frequency of bilateral disease, although this topic has not been thoroughly studied. This study assessed the prevalence of multifocality in sMTC via a large international multi-institutional retrospective review to quantify this prevalence, including the impact of geography, to assess more accurately the risks associated with alternative surgical approaches. METHODS: A retrospective chart review of sMTC patients from 11 institutions over 29 years (1983-2011) was undertaken. Data regarding focality, extent of disease, RET germline analysis plus family and clinical history for multiple endocrine neoplasia type 2 (MEN2), and demographic data were collected and analyzed. RESULTS: Patients from four continents and seven countries were included in the sample. Data for 313 patients with documented sMTC were collected. Of these, 81.2% were confirmed with negative RET germline testing, while the remaining 18.8% demonstrated a negative family history and no manifestations of MEN2 syndromes other than MTC. Bilateral disease was identified in 17/306 (5.6%) patients, while multifocal disease was noted in 50/312 (16.0%) sMTC patients. When only accounting for germline negative patients, these rates were not significantly different (5.6% and 17%, respectively). Among them, when disease was unifocal in the ipsilateral lobe and isthmus, bilateral disease was present in 6/212 (2.8%) cases. When disease was multifocal in the ipsilateral lobe or isthmus, then bilateral disease was present in 8/37 (21.6%) cases (p < 0.001). No geographic differences in focality were identified. CONCLUSIONS: The 5.6% prevalence of bilateral foci in sMTC suggests that total thyroidectomy should remain the standard of care for initial surgery, as less complete thyroid surgery may fail to address fully the primary site of disease. Whether ipsilateral tumor focality should be an independent factor determining the need for completion thyroidectomy when sMTC is diagnosed after hemithyroidectomy remains to be determined.

PURPOSE: To compare outcomes in pediatric patients suffering forceful head impact during recreational vehicle use to patients with forceful head impact from other mechanisms. METHODS: Retrospective cohort study of all patients 3-18 years old who suffered forceful head impact (any traumatic mechanism strong enough to result in a face or skull fracture) in our institutional trauma registry between January 2011 and September 2013. RESULTS: Out of 252 events involving forceful head impact, 64 events were a result of riding a recreational vehicle. Although there is no difference in rates of temporal bone fractures, recreational vehicle accidents have higher rates of otic capsule violation (21% vs. 5%) and higher rates of hearing loss (30% vs 16%) compared to patients with forceful head impact from other mechanisms. All incidents of otic capsule violation and sensorineural hearing loss in recreational vehicle accidents were associated with a temporal bone fracture. CONCLUSION: Despite the increasing use of head protective gear while operating a recreational motor vehicle there is still heightened risk for temporal bone fractures and subsequent hearing loss. The comparative associations in this study suggest that helmets used with recreational vehicles do not protect the temporal bone thus leaving vital structures within the otic capsule at risk for damage and long term consequences. When treating these patients Otolaryngologists should be aware of the elevated risk of otic capsule violation and late hearing loss with temporal bone fractures.

OBJECTIVES: To evaluate the diagnostic accuracy of fine-needle aspiration biopsy (FNAB) to preoperatively diagnose medullary thyroid cancer (MTC) among multiple international centers and evaluate how the cytological diagnosis alone could impact patient management. METHODS: We performed a retrospective chart review of sporadic MTC (sMTC) patients from 12 institutions over the last 29 years. FNAB cytology results were compared to final pathologic diagnoses to calculate FNAB sensitivity. To evaluate the impact of cytology sensitivity for MTC according to current practice and to avoid confounding results by local treatment protocols, changes in treatment patterns over time, and the influence of ancillary findings (e.g., serum calcitonin), therapeutic interventions based on FNAB cytology alone were projected into 1 of 4 treatment categories: total thyroidectomy (TT) and central neck dissection (CND), TT without CND, diagnostic hemithyroidectomy, or observation. RESULTS: A total of 313 patients from 4 continents and 7 countries were included, 245 of whom underwent FNAB. FNAB cytology revealed MTC in 43.7% and possible MTC in an additional 2.4%. A total of 113 (46.1%) patients with surgical pathology revealing sMTC had FNAB findings that supported TT with CND, while 37 (15.1%) supported TT alone. In the remaining cases, diagnostic hemithyroidectomy and observation were projected in 32.7% and 6.1%, respectively. CONCLUSION: FNAB is an important diagnostic tool in the evaluation of thyroid nodules, but the low sensitivity of cytological evaluation alone in sMTC limits its ability to command an optimal preoperative evaluation and initial surgery in over half of affected patients.

Objective To evaluate lateral temporal bone resection (LTBR) in the management of advanced cutaneous squamous cell carcinoma (SCC) with temporal bone invasion and patterns of failure. Methods This is a retrospective study of 35 patients undergoing lateral temporal bone resection for advanced cutaneous SCC at a tertiary care center between 1995 and 2006. Results The Pittsburgh tumor stage was T4 in 18 patients (51%), T3 in 5 (14%), T2 in 9 (26%), and T1 in 3 (9%). Clear margins were reported in 22 (63%) patients. Resection of the mandible and/or temporomandibular joint (TMJ) was required in 11 (31%) patients. Facial nerve involvement was seen in 10 (29%) patients. Survival outcomes at 2 and 5 years for overall survival were 72% and 49%; disease-free survival, 68% and 59%; and disease-specific survival, 79% and 62%, respectively. Pittsburgh T stage correlated significantly with disease-specific survival (p = 0.015) and margin status was significant for both disease-free survival (p = 0.0015) and disease-specific survival (p < 0.001). Conclusions Surgery with curative intent is justified for cutaneous SCC invading the temporal bone with extended LTBR. Margin status was a significant predictor of outcome. Surgeons should plan preoperatively to achieve clear margins by extending the LTBR with possible nerve resection.
RESUMO
BACKGROUND: Ectopic mediastinal goiter is a rare entity that presents diagnostic and treatment challenges to the clinician. METHODS: A case of primary ectopic mediastinal goiter is presented and use of a cervical approach for excision is described herein. Additionally, precedent literature highlighting surgical treatment approaches is reviewed. RESULTS: The distinction between primary and secondary ectopic mediastinal goiter is significant as this indicates the vascular supply to the ectopic mass. Previous authors suggested open thoracic procedures for all primary mediastinal goiters to safely divide intrathoracic vascular supply, but favorably positioned anterior mediastinal goiter may be safely removed via cervical approach. This is the second case of primary ectopic mediastinal goiter successfully resected via cervical approach. CONCLUSION: Select cases of primary mediastinal goiter may be amenable to excision via cervical approach, avoiding potential complications of open thoracic procedures. Additionally, CT-guided biopsy is an effective tool in preoperative diagnosis of anterior mediastinal masses.
