Abstract
OBJECTIVE Temporal bone squamous cell carcinoma (TBSCC) is rare and often confers a poor prognosis. The aim of this study was to synthesize survival and recurrence outcomes data reported in the literature for patients who underwent temporal bone resection (TBR) for curative management of TBSCC. We considered TBSCC listed as originating from multiple subsites, including the external ear, parotid, and external auditory canal (EAC), or nonspecifically from the temporal bone. DATA SOURCES PubMed, Cochrane Library, Embase, and manual search of bibliographies. REVIEW METHOD A systematic literature review conducted in December 2020 according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS Survival data were collected from 51 retrospective studies, resulting in a pooled cohort of 501 patients with TBSCC. Compared to patients undergoing lateral TBR (LTBR), patients undergoing subtotal (SBTR) or total (TTBR) TBR exhibited significantly higher rates of stage IV disease (P < .001), positive surgical margins (P < .001), facial nerve involvement (P < .001), and recurrent disease (P < .001). A meta-analysis of 15 studies revealed a statistically significant 97% increase in mortality in patients who underwent STBR or TTBR. On multivariate analysis, recurrent disease was independently associated with worse overall survival (P < .001). On univariate analysis, facial nerve involvement was also associated with decreased overall survival (P < .001). CONCLUSION Recurrent disease was associated with risk of death in patients undergoing TBR. Larger prospective multi-institutional studies are needed to ascertain prognostic factors for a wider array of postoperative outcomes, including histology-specific survival and recurrence outcomes.

Abstract
Multidisciplinary treatments with surgery, radiation therapy, and chemotherapy are the cornerstones in the management of locally advanced head and neck malignancies. In most cases, radiation is delivered via external beam radiation therapy (EBRT). Intraoperative radiation therapy (IORT), on the other hand, is the delivery of precise doses of radiation to selected target volumes within the exposed surgical field while at the operating room. Most studies on its use on head and neck cancers are limited to single-institutional retrospective case series. We performed a systematic review to consolidate the existing literature on IORT for head and neck malignancies. Fifty-two studies representing a mixed population of 2,389 patients were included in this review. IORT via electrons (intraoperative electron radiation therapy), brachytherapy (intraoperative high dose-rate brachytherapy) or photons was administered in numerous settings, but most commonly as part of a reirradiation regimen following salvage surgery for recurrent tumours. Often, additional EBRT was also planned postoperatively. This review illustrates that IORT is a promising treatment modality in head and neck cancer. Multiple single-institutional studies spanning several decades have demonstrated benefit in terms of local control with reasonable toxicity. However, randomised trials comparing it with current standards of care are still needed.

Treatment of advanced squamous cell carcinoma of the external auditory canal: Critical analysis of persistent failures in diagnosis and surgery with a competing-risk model. Head Neck 2022; 44:1918-1926.

Abstract
BACKGROUND A series of temporal bone squamous cell carcinomas (TBSCCs) was analyzed with the aim of (i) better understanding the causes for the persistent high failure rate in advanced SCCs and (ii) discussing a possible way out from this stalemate in treatment. METHODS Forty-five TBSCCs consecutively treated surgically were reviewed. RESULTS The 5-year cumulative incidence for postoperative local recurrence was 41.8%. At multivariable analysis, pT3-4 stages were associated with eightfold relative incidence of developing local recurrence during follow-up (sHR = 9.06, 95% confidence interval [CI] = 1.18-69.46, p = 0.034) and cause-specific death (sHR = 7.95, 95%CI = 1.01-62.27, p = 0.048). CONCLUSIONS The poor outcome in advanced TBSCC occurred because of local recurrence due to defective resection. The fundamental pitfall of surgery on advanced TBSCC appeared to be the insufficient knowledge of microscopic tumor growth in the different sites and subsites of the temporal bone. The serial histopathological study of the en bloc surgical specimen and autopsy temporal bones seems to represent a way to enhance our understanding of these tumors.

Abstract
PURPOSE Primary: To determine the rate of occult cervical metastases in primary temporal bone squamous cell carcinomas (TBSSC). Secondary: to perform a subgroup meta-analysis of the risk of occult metastases based on the clinical stage of the tumour and its risk based on corresponding levels of the neck. METHODS A systematic review and meta-analysis of papers searched through Medline, Cochrane, Embase, Scopus and Web of Science up to November 2021 to determine the pooled rate of occult lymph node/parotid metastases. Quality assessment of the included studies was assessed through the Newcastle-Ottawa scale. RESULTS Overall, 13 out of 3301 screened studies met the inclusion criteria, for a total of 1120 patients of which 550 had TBSCC. Out of the 267 patients who underwent a neck dissection, 33 had positive lymph nodes giving a pooled rate of occult metastases of 14% (95% CI 10-19%). Occult metastases rate varied according to Modified Pittsburg staging system, being 0% (0-16%) among 12 pT1, 7% (2-20%) among 43 pT2 cases, 21% (11-38%) among 45 pT3, and 18% (11-27%) among 102 pT4 cases. Data available showed that most of the positive nodes were in Level II. CONCLUSION The rate of occult cervical metastases in TBSCC increases with pathological T category with majority of nodal disease found in level II of the neck.

Abstract
Objective: Repeated computed tomography (CT) is essential for diagnosis, surgical planning and follow-up in patients with middle and inner ear pathology. Dose reduction to “as low as diagnostically acceptable” (ALADA) is preferable but challenging. We aimed to compare the diagnostic quality of images of subtle temporal bone structures produced with low doses (LD) and reference protocols (RP). Methods: Two formalin-fixed human cadaver heads were scanned using a 64-slice CT scanner and cone-beam CT (CBCT). The protocols were: RP (120 kV, 250 mA, CTDIvol 83.72 mGy), LD1 (100 kV, 80 mA, CTDIvol 26.79 mGy), LD2 (100 kV, 35 mA, CTDIvol 7.66 mGy), LD3 (80 kV, 40 mA, CTDIvol 4.82 mGy), and CBCT standard protocol. Temporal bone structures were assessed using a 5-point scale. Results: A median score of ≥2 was achieved with protocols such as the tendons of m. tensor tympani (RP/LD1/LD2/CBCT) and m. stapedius (CBCT), the incudostapedial joint (RP/LD1/CBCT), the incudomalleolar joint (RP/LD1/LD2/CBCT), the stapes feet (RP/LD1/CBCT), the stapes head (RP/LD1/LD2/CBCT), the tympanic membrane (RP/LD1/LD2/CBCT), the lamina spiralis ossea (none), the chorda tympani (RP/LD1/CBCT), and the modiolus (RP/LD1/LD2/CBCT). Adaptive statistical iterative reconstructions did not show advantages over the filtered back projection. Conclusions: LD protocols using a CTDIvol of 7.66 mGy may be sufficient for the identification of temporal bone structures.

Abstract
Objective Evaluation of the management and survival in patients treated for temporal bone squamous cell carcinoma (TBSCC) in a tertiary referral centre. Methods Forty-nine patients underwent primary treatment for TBSCC. Thirty-six patients underwent a lateral temporal bone resection (LTBR) or subtotal temporal bone resection (STBR). Overall survival (OS) and disease-specific survival (DSS) analysis were assessed. Results Five-year OS of the 49 patients was 39%. Five-year OS of the 36 patients who underwent LTBR or STBR was 46%. Tumour-free margins were achieved in all patients with T1 and T2 disease, in 59% patients with T3 tumours and 0% patients with T4 disease. Five-year DSS was 85% for all T1/T2 tumours, 53% for T3 tumours and 0% for T4 tumours. Clear resection margins was the only significant predictor of DSS in our cohort. Conclusions The mainstay of treatment for TBSCC is temporal bone resection with tumour free resection margins, with or without adjuvant radiotherapy. Survival is negatively influenced by non-radical resection. T1 and T2 tumours can be managed safely with LTBR. More advanced disease requires a more extensive resection, with a higher likelihood of non-radical resections and decreased survival rates.

Abstract
BACKGROUND The importance of elective parotidectomy in early-stage squamous cell carcinoma (SCC) of the external auditory canal (EAC) is not well established. METHODS A retrospective study of 43 patients with early-stage SCC of the EAC who underwent parotidectomy in conjunction with lateral temporal bone resection at three centers. RESULTS Overall occult parotid involvement (OPI) rate in early-stage SCC of the EAC was 13.9% (6/43). When considering both the anteroposterior position and the bony-cartilaginous position, patients with SCC in both the anterior wall and cartilaginous portion exhibited significantly higher OPI than other locations (37.5% vs. 0%, p = 0.001), with an increase in the OPI predictive value. CONCLUSION SCC located in either the anterior wall of the EAC or the cartilaginous portion of the EAC or both simultaneously showed a high prevalence of OPI, and elective parotidectomy should be considered in those patients.

Abstract
OBJECTIVE This study aimed to provide a systematic review on survival outcome based on Pittsburgh T-staging for patients with primary external auditory canal squamous cell carcinoma. METHOD This study was a systematic review in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines performed until January 2018; pertinent studies were screened. Quality of evidence was assessed using the grading of recommendation, assessment, development and evaluation working group system. RESULTS Eight articles were chosen that reported on 437 patients with external auditory carcinoma. The 5-year overall survival rate was 53.0 per cent. The pooled proportion of survivors at 5 years for T1 tumours was 88.4 per cent and for T2 tumours was 88.6 per cent. For the combined population of T1 and T2 cancer patients, it was 84.5 per cent. For T3 and T4 tumours, it was 53.3 per cent and 26.8 per cent, respectively, whereas for T3 and T4 tumours combined, it was 40.4 per cent. Individual analysis of 61 patients with presence of cervical nodes showed a poor survival rate. CONCLUSION From this review, there was not any significant difference found in the survival outcome between T1 and T2 tumours. A practical classification incorporating nodal status that accurately stratifies patients was proposed.

Abstract
Background and aims Squamous cell carcinoma (SCC) of the temporal bone is a rare malignancy accounting for only 0.2% of head and neck cancers. There is currently no clear consensus on staging or common approach to management. It is the aim of this work to provide the readers with a review of the current literature on this malignancy. Methods A literature review was performed identifying 16 case series with patient numbers ranging from 12 to 124. A total of 708 patients were included in this review, 67% presented with advanced disease. 578 cases were managed operatively with lateral temporal bone resection, some underwent local resection alone in early stage disease. In all studies radiation therapy was used as an adjunct to some degree. Results More than half of studies reported 100% either 2-, 3- or 5-year survival for T1 and T2 disease with no nodal involvement. Survival correlated with disease stage and in five studies SCC differentiation was found to be a significant prognostic factor. Post-operative radiotherapy was found to improve survival in only one study. Conclusions Temporal bone SCC is a readily treatable malignancy in early stage disease, however late stage disease has a poor prognosis. Differentiation of the SCC and stage of disease at presentation appear to have the greatest influence on 5-year survival rates. Further work is required in both the identification of early stage disease and in the treatment of later T3 and T4 lesions.

Abstract
Adenoid cystic carcinoma (ACC) of the external auditory canal (EAC) is a rare tumor. The present study aimed to describe the clinical features and survival of patients with ACC of the EAC. The present retrospective study included 23 patients (mean age, 51.4±15.4 years; 12 males) diagnosed with ACC of the EAC between January 2010 and September 2017 at The First Affiliated Hospital of The Third Military Medical University (Chongqing, China). The median disease course was 24 months. The presenting features were earache in 16 patients, otorrhea in 7 patients, hearing loss in 5 patients, feeling of aural fullness in 2 patients and EAC mass in 4 patients. Tumor stage was T1 in 13 patients, T2 in 3 patients, T3 in 3 patients and T4 in 4 patients. Among patients with T1 tumors, 5 underwent en bloc external EAC resection; 3 underwent local EAC resection; 1 underwent en bloc EAC resection and superficial parotidectomy; 1 underwent subtotal temporal bone resection for postoperative recurrence; Among patients with T4 tumors, 1 underwent extended temporal bone resection, right parotidectomy, right resection of middle cranial fossa tumors and right resection of temporomandibular joint capsule. 1 underwent subtotal temporal bone resection. Among these 15 patients who underwent surgery, 2 received postoperative radiotherapy, 1 received postoperative chemotherapy, 5 received postoperative chemo-radiotherapy, and 7 did not receive postoperative chemo-radiotherapy. The 3- and 5-year cumulative survival rates of the 23 patients were 47.8% and 17.4%, respectively. Survival may have been improved in patients who received postoperative chemo-radiotherapy and early diagnosis may be the key to improving survival.

Abstract
OBJECTIVES The rarity of temporal bone squamous cell carcinoma (TBSCC) precludes a clear understanding of the disease and approach to its management. This review provides general background on the disease and discusses the current and emerging oncologic and rehabilitative management options. DATA SOURCES PubMed literature review. METHODS A review of the current literature was conducted to assess and collate up-to-date information regarding TBSCC management. RESULTS TBSCC is a rare and aggressive disease arising in the ear canal, temporal bone, or extratemporal sites. Prior radiation, chronic ear disease, or habitual ear picking may contribute to primary disease development. Because the symptoms of TBSCC and benign otologic disease are similar, TBSCC diagnosis may be delayed, allowing the tumor time to spread throughout the anatomically intricate temporal bone. The extent of the disease is determined based on imaging and is usually staged with the Pittsburgh Staging System. Temporal bone resection with parotidectomy and neck dissection is the current standard of care. Survival is generally good for early disease and poor for advanced disease, but chemotherapy is emerging as a promising treatment option. Auditory rehabilitation with osseointegrated hearing aids is recommended at initial oncologic resection. CONCLUSIONS The knowledge of and outcomes for TBSCC have improved with time, but because of the aggressive nature of the disease and the anatomic intricacy of the temporal bone, TBSCC treatment is complex and should be delivered by a multidisciplinary team. Inter-institutional collaboration may accelerate research for this rare disease. LEVEL OF EVIDENCE 5.

Abstract
The International Collaboration on Cancer Reporting (ICCR) was established to internationally unify and standardize the pathologic reporting of cancers based on collected evidence, as well as to allow systematic multi-institutional intercountry data collection to guide cancer care in the future. Such collaborative efforts are particularly essential for developing an evidence base for rare neoplasms or those with marked geographic variation in incidence, such as the tumors of the ear and the temporal bone. The ear and the temporal bone, including the external auditory canal and the middle and inner ear, with the closely associated facial nerve, internal carotid artery, and internal jugular vein, is one of the most complex anatomic structures in the head and neck. A wide range of benign and malignant neoplasms arise in this region. The management of these neoplasms involves complex surgery because of the anatomic confines, and as such, both benign and malignant tumors are included in this data set, as the oncologically equivalent management requires a multidisciplinary approach and standardized nomenclature and terminology. Surgical procedures at this site result in multifaceted 3-dimensional specimens that can be difficult to handle at macroscopic exam. A comprehensive macroscopic examination is important for identifying critical prognostic factors and often requires clinical and radiologic correlation. Histologic examination is straightforward for basal cell or squamous cell carcinoma but can be quite challenging for other neoplasms. A summary of the ICCR guidelines for ear tumors is presented, along with discussion of the salient evidence and practical issues.

Abstract
OBJECTIVE In advanced temporal bone carcinoma cases, we attempted to preserve as much of the auricle as possible from a cosmetic and functional perspective. Difficulties are associated with selecting an adequate position for reconstructed auricles intraoperatively. We improved the surgical procedure to achieve a good postoperative auricle position. METHODS Nine patients were included in this study. All patients underwent subtotal removal of the temporal bone and resection of the external auditory canal while preserving most of the external ear, and lateral skull base reconstruction was performed with anterolateral thigh flaps. We invented a new device, the auricle localizer, to select the correct position for the replaced external ear. The head skin incision line and two points of three-point pin fixation were used as criteria, and a Kirschner wire was shaped as a basic line to match these criteria. Another Kirschner wire was shaped by wrapping it around the inferior edge of the external ear as the positioning line, and these two lines were then combined. To evaluate the postoperative auricle position, the auricle inclination angle was measured using head frontal cephalogram imaging. RESULTS The external ear on the affected side clearly drooped postoperatively in nonlocalizer cases, whereas this was not obvious in localizer cases. Auricle inclination angles 1 year after surgery significantly differed between these two cases (P = 0.018). CONCLUSION The surgical device, the auricle localizer, is useful for selecting intraoperative accurate auricle positions. The assessment index, the auricle inclination angle, is useful for quantitatively evaluating postoperative results. LEVEL OF EVIDENCE 4 Laryngoscope, 2605-2610, 2018.

Abstract
AIM Prognostic factors, rational management, and the ongoing investigations regarding temporal bone squamous cell carcinoma (TBSCC) have been critically reviewed. BACKGROUND TBSCC is an uncommon, aggressive malignancy. Although some progress has been made in treating this aggressive tumor, the prognosis in advanced cases remains poor. MATERIALS AND METHODS A systematic search of the literature for articles published between 2009 and October 2014 was performed using the PubMed (http://www.pubmed.gov) electronic database. RESULTS Given the particular anatomical site of TBSCC, its prognosis is significantly influenced by any direct involvement of nearby structures. The extent of the primary tumor is generally considered one of the most important prognostic factors and it is frequently related to prognosis even more strongly than N stage. For TBSCC, biomarker investigations in surgical specimens are only just beginning to appear in the oncological literature. CONCLUSION Given the particular features of TBSCC, the sub-specialty of otologic oncology seems to be emerging as a defined area of practice involving multidisciplinary team comprising oto-neurosurgeons, head and neck surgeons, plastic surgeons, oncologists, radiotherapists, dedicated radiologists, and pathologists.

Abstract
The objective of this study was to evaluate the safety, effectiveness and functional outcomes of intraoperative radiotherapy (IORT) followed by intensity-modulated radiation therapy (IMRT) in locally advanced stage tumours involving the middle ear. Data on 13 consecutive patients treated for malignant tumor of external auditory canal involving the middle ear were retrospectively reviewed. Median follow-up was 33 months (range 6-133). Five (38%) patients were stage III and 8 (62%) were Stage IV according to the University of Pittsburgh staging system. Lateral temporal bone resection (LTBR) was performed in all cases. LTBR was associated with parotidectomy in 5 (38%) cases, and with neck dissection and parotidectomy in 6 (46%) cases. No patients had gross residual tumour. Surgical treatment was followed by IORT (12 Gy) and IMRT (50 Gy). Adjuvant chemotherapy was used in 4 (30%) cases. Preoperative and postoperative audiometric tests were performed to assess hearing loss. 5-year local-control (LC), 5-year distant-metastasis (DM), 5-year disease-free-survival (DFS) and 5-year overall-survival (OS) were calculated with Kaplan-Meyer method. Significant changes in bone conduction were reported after treatment. Partial flap necrosis was the only early complication observed in three (23%) cases, while meningeal fistula was seen in one (7.6%) case as a late complication. The 5-year LC-rate was 68%. The 5-year DM-rate was 90%. The 5-year DFS-rate was 61%. The 5-year OS-rate was 69%. IORT followed by IMRT for the treatment of advanced external auditory canal and middle ear tumours seems to be safe. No intraoperative death was reported. IORT may reduce the postoperative irradiation of remnant tissue obtaining the same full dose on the tumour bed. No complications of the residual external ear were observed. Detriment of neurosensory hearing may be expected. Future studies are required to confirm the benefit of this procedure in the ear.

Abstract
OBJECTIVE To report a rare case of recurrent temporal bone carcinoma encasing the carotid artery. PATIENT A 54-year-old man underwent mastoidectomy combined with adjuvant chemoradiotherapy of squamous cell carcinoma of the temporal bone. He developed metastatic disease and received parotidectomy and lymph node dissection. Three months later, the magnetic resonance imaging scan showed that the tumor had relapsed and invaded the carotid artery. INTERVENTION The patient completed TPF-C induction chemotherapy (docetaxel, cisplatin, 5-fluorouracil, cetuximab), followed by concurrent chemotherapy with reirradiation. RESULTS Magnetic resonance imaging revealed a complete response of tumor 1 month after treatment. The patient had no detectable recurrence after 53 months of follow-up. CONCLUSION Concurrent chemotherapy with reirradiation is a potential curative treatment option for patients who have unresectable recurrent squamous cell carcinoma of the temporal bone.

Abstract
BACKGROUND Subtotal temporal bone resection (STBR) has been used for half a century to remove temporal bone malignancies. However, there are few reports on the detailed anatomy involved in the resection. OBJECTIVE To describe the microsurgical anatomy of STBR combined en bloc with the resection of the parotid gland and temporomandibular joint (TMJ). METHODS Cadaveric specimens were dissected in a stepwise manner using 3× to 40× magnification. RESULTS STBR can be combined with the total parotidectomy and the resection of the TMJ if the tumor extends into the parotid gland, TMJ, or facial nerve. In this study, we describe the step-by-step microsurgical anatomy of STBR en bloc with the parotid gland and TMJ. The surgical technique described combines 3 approaches: the high cervical, subtemporal-infratemporal fossa, and retromastoid-paracondylar approaches. Combining these 3 approaches aided in efficiently completing this modified approach. CONCLUSION STBR is a complicated and technically challenging procedure. This study highlights the importance of understanding the surgical anatomy of STBR and will serve as a catalyst for improvement of the surgical technique for temporal bone resection.

Abstract
BACKGROUND The standard treatment for advanced external auditory canal squamous cell carcinoma (SCC) is subtotal temporal bone resection and postoperative radiation therapy (RT), whereas chemoradiation therapy (CRT) is used in some institutions to improve patient prognosis. The purpose of this study was to evaluate the efficacy of CRT in external auditory canal SCC treatment. METHODS Meta-analyses of external auditory canal SCC studies were performed. We extracted 5-year overall survival rates and number of patients for aggregate patient data, and types of treatment and outcomes for individual patient data. RESULTS The 5-year overall survival rate of 752 patients was 57%. In the individual patient data meta-analysis, the 5-year overall survival rates of patients who received surgery ± RT, preoperative CRT, definitive CRT, and postoperative CRT were 53.5%, 85.7%, 43.6%, and 0%, respectively. CONCLUSION Our data suggest that preoperative CRT may improve the survival of surgically treated patients with external auditory canal SCC and that definitive CRT may be equivalent to surgical resection.

Abstract
BACKGROUND The correlation between the survival rate and various invasion patterns of patients with temporal bone squamous cell carcinoma (SCC) is unclear. This study was performed to compare the survival outcomes of these patients to disclose the correlation. METHODS The cases of 39 patients with temporal bone SCC who underwent surgery between January 2004 and December 2012 were reviewed. RESULTS The 2-year overall survival rate was 56.9%, and it was 22.3% for patients with stage IV disease, and 100% for patients with stage I-III disease. Patients with parotid invasion (n = 11), temporomandibular joint (TMJ) involvement (n = 8), and middle ear surgery (n = 7) before temporal bone malignancies were diagnosed had poor survival with statistical difference. CONCLUSION Patients with parotid gland, TMJ involvement, and previous middle ear surgery for chronic otitis media had poor outcomes.

Abstract
AbstractObjective:This study aimed to investigate the computed tomography and magnetic resonance imaging findings of primary middle-ear carcinoma.Methods:In this retrospective study of 13 patients with primary middle-ear carcinoma, we collected pre- and post-contrast magnetic resonance images for all 13 cases, high-resolution computed tomography scans for 11 cases, and conventional computed tomography scans with contrast for 2 cases.Results:Soft-tissue masses were mainly located in the tympanum, tympanic sinus and deep within the external auditory canal, and involved the jugular fossa (9 of 13 patients), middle cranial fossa (5/13), parotid gland (2/13) and temporomandibular joint fossa (1/13). An irregular, ‘moth-eaten’ bone destruction pattern was seen on high-resolution computed tomography images, most commonly in the eustachian tube (9/13), jugular foramen (9/13) and facial nerve canal (7/13). On non-contrast magnetic resonances images, masses were isointense or slightly hypointense on T1-weighted images, and isointense or slightly hyperintense on T2-weighted images. On post-contrast images, lesions were moderately and homogeneously enhanced in seven cases and inhomogeneously enhanced in six.Conclusion:High-resolution computed tomography precisely detects regions of bone destruction, whereas MRI can better assess soft-tissue tumour margins, intracranial extension and vessel patency. Eustachian tube erosion is an important characteristic of primary middle-ear carcinoma.

Abstract
External auditory canal (EAC) carcinomas are frequently misdiagnosed. The aim of this study was to conduct a review of misdiagnosed cases and analyze the factors involved. This study was a retrospective assessment. Eighteen of 44 EAC carcinoma cases seen at the Eye and ENT Hospital were misdiagnosed. All medical records were retrospectively analyzed for the age, sex, presenting symptoms, type of misdiagnosis, computed tomographic (CT) or magnetic resonance imaging (MRI) findings, stage of the cancer, surgical approach, histopathological examination, adjunctive therapy (postoperative radiotherapy) and outcomes of treatment. Six cases were misdiagnosed as otitis media, five cases were misdiagnosed as otitis externa, and two cases were misdiagnosed as external auditory canal cholesteatomas. Other misdiagnoses were stenosis of the EAC, ear neuralgia, furuncle of the EAC, benign neoplasm of the EAC and pre-auricular fistula. Our analyses suggest that a biopsy should be conducted to obtain a histopathological diagnosis if an EAC carcinoma is suspected, in case otitis media or otitis externa does not respond to routine anti-bacterials. Head and neck MRI should be used to explore the involvement of soft tissues. Patients with bloody ear discharge and otalgia, particularly with temporal bone erosion seen in a CT scan, are highly likely to have a malignant carcinoma of the temporal bone.

Abstract
OBJECTIVE To evaluate surgical outcomes for squamous cell carcinoma of the temporal bone. STUDY DESIGN Retrospective study. SETTING Eye and ENT Hospital. METHODS Seventy-two patients with squamous cell carcinoma of the temporal bone were analyzed for survival. The patients were staged according to the modified Pittsburgh staging system. Five patients with T1 cancers underwent local resection (LR), and 10 patients with T1 cancers underwent lateral temporal bone resection (LTBR). Two patients with T2 cancers underwent LR, and 1 patient with T2 cancer underwent LTBR. One patient with T3 cancer underwent LR, 8 patients with T3 cancers underwent LTBR, and 10 patients with T3 cancers underwent subtotal temporal bone resection (STBR). Ten patients with T4 cancers underwent LTBR, and 25 patients with T4 cancers underwent STBR. RESULTS Of all patients that underwent surgery, 18 died of their disease during the follow-up time. The 5-year survival rates of patients with T stages 1 through 4 were 100%, 67%, 21%, and 14%, respectively. There was no statistically significant difference in 5-year survival rate between T3 and T4 using the log-rank test (p > 0.05). The 5-year survival rates after LTBR and STBR for T3 were 26% and 16% (p > 0.05), respectively, and those for T4 were 17% and 11% (p > 0.05), respectively. CONCLUSION An en bloc resection is favored in an effort to produce negative surgical margins for squamous cell carcinoma of the temporal bone. Adjunctive radiotherapy is used for advanced lesions.

Abstract
BACKGROUND The purpose of this study was to identify factors predictive of outcome in patients undergoing temporal bone resection (TBR) for head and neck cancer. METHODS This was a retrospective study of 72 patients undergoing TBR. Factors associated with survival and recurrence were identified on multivariable regression. RESULTS Most tumors were epithelial (81%), commonly (69%) involving critical structures. Cervical metastases were uncommon (6%). Squamous cell carcinoma (SCC) of the external auditory canal carried a high rate of parotid invasion (25%) and parotid nodal metastases (43%). The 5-year rate of overall survival (OS) was 62%; disease-specific survival (DSS), 70%; recurrence-free survival (RFS), 46%. Factors independently associated with outcome on multivariable analysis were margin status and extratemporal spread of disease to the parotid, mandible, or regional nodes. Recurrence was common (72%) in cT3-4 tumors. CONCLUSIONS Margin status and extratemporal disease spread are the strongest independent predictors of survival and recurrence. In SCC of the external auditory canal, high rates of parotid involvement support adjunctive parotidectomy. Risk of recurrence in T3-T4 tumors may support a role for adjuvant therapy.

Abstract
OBJECTIVES/HYPOTHESIS To evaluate survival outcomes in patients undergoing temporal bone resection. STUDY DESIGN Retrospective review. METHODS From 2002 to 2009 a total of 65 patients underwent temporal bone resection for epithelial (n = 47) and salivary (n = 18) skull base malignancies. Tumor characteristics, defect reconstruction, and postoperative course were assessed. Outcomes measured included disease-free survival and cancer recurrence. RESULTS The majority of patients presented with recurrent (65%), advanced stage (94%), cutaneous (72%), and squamous cell carcinoma (57%). Thirty-nine patients had perineural invasion (60%) and required facial nerve resection; 16 (25%) had intracranial extension. Local (n = 6), regional (n = 2), or free flap (n = 46) reconstruction was required in 80% of patients. Free flap donor sites included the anterolateral thigh (31%), radial forearm free flap (19%), rectus (35%), and latissimus (4%). The average hospital stay was 4.9 days (range, 1-28 days). The overall complication rate was 15% and included stroke (n = 4), cerebrospinal fluid leak (n = 2), hematoma formation (n = 1), infection (n = 1), flap loss (n = 1), and postoperative myocardial infarction (n = 1). A total of 22 patients (34%) developed cancer recurrence during the follow-up period (median, 10 months), 17 (77%) of whom presented with recurrent disease at the time of temporal bone resection. Two-year disease-free survival was 68%, and 5-year disease-free survival was 50%. CONCLUSIONS Aggressive surgical resection and reconstruction is recommended for primary and recurrent skull base malignancies with acceptable morbidity and improved disease-free survival.

Abstract
Verrucous carcinoma is a rare tumor that presents in the head and neck with the most common sites being the oral cavity and larynx. Fourteen cases of verrucous carcinoma of the temporal bone have been described in literature; this study aims to examine treatment outcomes and discuss the controversy surrounding postoperative radiation. The study design included a literature review along with individual case report in the setting of a tertiary care medical center. Outcome analysis of all cases of verrucous carcinoma of the temporal bone, which are documented in the English literature, and presentation of a single patient report including gross, histologic and radiologic analyses were performed. The longest recorded survival for verrucous carcinoma of the temporal bone occurs in patients treated with surgery alone. Poorer outcomes for patients treated with adjuvant (chemo)radiation may be due to more advanced stage of disease at the time of treatment. Early reports of radiation leading to tumor dedifferentiation or early recurrence are not supported by more recent studies. Whether adjuvant radiation therapy is indicated in verrucous carcinoma of the temporal bone remains controversial.

Abstract
The ear canal, middle ear and temporal bone are rare sites of primary cancer. However, given its central location within the skull base, the tumors from these sites often extend to involve the parotid, overlying skin and even the dura or carotid artery. Squamous cell carcinoma is the most common histology for both primary and secondary tumors. The rarity of temporal bone cancers and the complexity of the region's anatomy make treating temporal bone malignancies difficult. While early-stage cancers can be effectively treated by complete resection, multimodal therapy is imperative for most of these tumors. A contemporary review of the literature is presented with present-day controversies outlined.
