OBJECTIVE: The aim of this study was to assess the surgical results of a series of patients from this unit who underwent extended temporal bone resection for recurrent squamous cell carcinoma as a salvage procedure. DESIGN: The surgical records of 15 patients were analyzed in detail. Each patient had salvage surgery in the form of an extended temporal bone resection with supraomohyoid block dissection, dural grafting, and free microvascular forearm or scalp rotation flap repair for recurrent squamous cell carcinoma in a radical mastoid cavity. RESULTS: Radical surgery yielded a 47% 5-year survival. Twenty-nine percent of the survivors had temporal lobe involvement that necessitated a partial excision of the temporal lobe of the brain. Histologic evidence of local lymph node involvement in the supraomohyoid neck dissection was present in 13% of cases. Those who died did so in the first postoperative year. All those with poorly differentiated tumors died. The survivors had well or moderately differentiated tumors. CONCLUSIONS: Radiotherapy alone or partial temporal bone resection, most commonly a radical mastoidectomy with or without preoperative or postoperative radiotherapy is used by the majority of otolaryngologists in treating squamous cell carcinoma of the temporal bone. The 5-year survival rate after this treatment remains depressingly low and the prognosis gloomy, particularly for advanced tumors. The findings in this series of extended temporal bone resections as salvage surgery in recurrent disease is encouraging, and radical surgery combined with radiotherapy from the outset may give much better 5-year survival figures in the future than the conventional partial temporal bone resection and radiotherapy.

Temporal Bone Resection

A retrospective study of 35 patients with squamous cell carcinoma of the external auditory meatus treated at the Eye and Ear Hospital of the University of Pittsburgh was performed. The standard treatment was a temporal bone resection that corresponded to the extent of the lesion, followed by postoperative radiation therapy. The tumor extensions, symptoms, treatments, survival rates, and prognostic variables were reviewed. Overall, 12 of 35 patients survived. Lesions limited to the external auditory meatus with no erosion had excellent prognoses. Survival in intermediate lesions with bony erosion or middle ear Involvement was related to the status of surgical margins after partial or subtotal temporal bone resections. Extensive lesions that involved the surrounding soft tissue or dura had poor prognoses. The survival value of total temporal bone resection remains unproved.

Abstract Objectives To evaluate the outcomes for patients after lateral temporal bone resection surgery for cutaneous squamous cell carcinoma and basal cell carcinoma, and to ascertain predictors of survival and treatment failure. Methods A retrospective review was conducted of the medical records for all patients who underwent lateral temporal bone resection for cutaneous squamous cell carcinoma or basal cell carcinoma between 2007 and 2019 in Western Australia. Results Thirty-seven patients underwent lateral temporal bone resection surgery. Median follow-up duration was 22 months. Twenty-five patients had squamous cell carcinoma and 12 had basal cell carcinoma. The overall survival rate at two years for patients with squamous cell carcinoma was 68.5 per cent. Pre-operative facial nerve involvement (determined via clinical or radiological evidence) was identified as a predictor of mortality (hazard ratio = 3.411, p = 0.006), with all patients dying before two years post-operatively. Locoregional tumour control was achieved in 81 per cent of cases (n = 30). Conclusion Lateral temporal bone resection offers acceptable local control rates and survival outcomes. Caution should be used in offering this surgery to patients with clinical or radiological evidence of facial nerve involvement because of the relatively poorer survival outcomes in this subgroup.

Abstract Objective En bloc and margin-negative surgical resection seems to offer the best prognosis for patients with temporal bone squamous cell carcinoma (TB-SCC). In this study, we summarize the outcomes of surgical cases of advanced TB-SCC (T3–T4) that were managed in two institutions, with an accompanying description of the surgical procedure that was utilized: modified subtotal temporal bone resection (STBR), which involves the en bloc removal of the temporal bone including or transecting the otic capsule. Design This is a case series study with chart review. Setting The study was conducted at two academic tertiary care medical centers. Participants Chart information was collected for all patients who underwent surgical resection of advanced TB-SCC between July 1998 and February 2019. The resulting dataset contained 43 patients with advanced TB-SCC who underwent en bloc resection during the review period. Tumor staging followed the modified Pittsburgh classification. Disease-specific survival (DSS) rates were calculated according to the Kaplan–Meier method. Main Outcome Measure This study shows disease-specific 5-year DSS rate. Results The 5-year DSS rate of the cases who underwent en bloc resection was 79.7%. En bloc lateral temporal bone resection was employed in a total of 25 cases (DSS: 79.0%). En bloc modified STBR was utilized in 18 cases (DSS: 81.7%). Conclusion En bloc margin-negative resection is a reliable treatment strategy for advanced TB-SCC. Modified STBR can be a treatment option for TB-SCC without marked posterior extension.

Temporal Bone Resection

Currently, only lateral temporal bone resection (LTBR) and subtotal temporal bone resection (STBR) are widely utilized for the surgical treatment of advanced squamous cell carcinoma of the external auditory canal (EAC-SCC). However, there are few descriptions of variations on these surgical approaches. This study aimed to elucidate the variations of en bloc resection for advanced EAC-SCC. We dissected the four sides of cadaveric heads to reveal the anatomical structures related to temporal bone resection. From the viewpoint of surgical anatomy, surgical patterns of temporal bone cutting can be divided into four categories: conventional LTBR, extended LTBR, conventional STBR, and modified STBR. Extended LTBR is divided into four types: superior, inferior, anterior, and posterior extensions. Several extension procedures can be combined based on the extension of the tumor. Furthermore, en bloc resection with the temporomandibular joint or glenoid fossa increases the technical difficulty of a surgical procedure because the exposure and manipulation of the petrous segment of the internal carotid artery are limited from the middle cranial fossa. Surgical approaches for advanced SCC of the temporal bone are diverse. They require accurate preoperative evaluation of the tumor extension and preoperative consideration of the exact line of resection to achieve marginal negative resection.
