Temporal Bone Resection

Abstract: Objective: Sacrificing the auricle has severe postoperative impacts on patients with temporal bone malignancy who have undergone en bloc temporal bone resection. The auricular complications following en bloc temporal bone resection remain unclear. Therefore, this study aimed to examine auricular complications following en bloc temporal bone resection and reveal the associated risk factors. Study Design: Case series with chart review. Setting: Single tertiary care medical center Participants: Our study includes all cases who underwent en bloc temporal bone resection with preserved auricle for temporal bone malignancy from January 1993 to July 2020. The resulting dataset contained 64 patients during the review period. Main outcome measures: We examined the relationship of auricular complications with surgical procedures and patient profiles. Results: Three of 64 cases (4.7%) showed postoperative auricular complication. The cause in all three cases was venous congestion. Postoperative bloodletting to relieve the congestion effectively salvaged the auricle in two of these cases. Insufficient bloodletting to relieve the auricular congestion in the remaining case led to auricular necrosis. Pre-/infra-auricular lymph node dissection is correlated with auricular complications with statistical significance. Conclusions: Temporal bone resection causes auricular congestion due to vascular insufficiency, particularly insufficient venous outflow. An immediate and continuous application of bloodletting can improve venous drainage after temporal bone resection to prevent auricle necrosis.

A New Technique

The purpose of this study is to describe a new technique for en bloc temporal bone resection using a diamond threadwire saw (T-saw) as an alternative to cutting the temporal bone with an osteotome. This technique has been performed in 10 patients with external auditory canal and middle ear cancers without any injury to the internal carotid artery or jugular vein. The authors conclude that the use of a diamond threadwire saw after transposing the internal carotid artery anteriorly is a safe, simple, and reliable technique for en bloc temporal bone resection.

✓ The authors report their technical experience with the en bloc subtotal temporal bone resection of cancer of the external ear involving the temporal bone. With the cooperation of an experienced plastic surgery team, coverage of the large defect with a rotation flap makes this procedure successful by wound healing per primam. Complications such as hemorrhage, vascular thrombosis, and brain abscess can be minimized by strict application of neurosurgical and plastic surgery techniques. Two successful cases are described in detail.

Eighteen temporal bones, 20 sets of polytomograms, and two sets of histologically sectioned temporal bones were studied and the literature was reviewed in order to describe the evolution and anatomic detail of the medial limits of the subtotal temporal bone resection used when malignant neoplasia has invaded the middle ear. An en bloc resection requires incisions medial to the pneumatized spaces involved. The anatomy of the lines of resection through the glenoid fossa, medial to the lateral wall of the carotid canal, through the cochlea, internal auditory canal, and jugular bulb, and just lateral to cranial nerves IX, X, and XI was described in detail. Regardless of the techniques employed, or the feasibility of the task, the concept of en bloc resection must conform to the anatomy of the region.

Abstract Temporal bone cancer is extremely rare; thus, the optimal surgical strategy for advanced tumors, en bloc vs piecemeal resection, remain controversial. Some authors have favored piecemeal resection and reported comparable outcomes.1 Other authors recommend the use of en bloc subtotal temporal bone resection (STBR) for advanced tumors and reported better outcomes, although long-term cancer control remains uncertain.2 Because of the technical difficulty and the lack of demonstrative surgical videos, STBR has not been sufficiently distributed. This video demonstrates en bloc STBR in a stepwise manner with particular focus on the neurosurgeon's role and aims to improve its safety, feasibility, and distribution. This video conforms to the description of Osawa et al3 in the designations for each segment of the petrous ICA. A 67-yr-old man suffered from consistent otorrhea and underwent tympanoplasty at an outside hospital 1 yr earlier. Following a histopathological diagnosis of squamous cell carcinoma in the specimen, he underwent chemoradiotherapy (cisplatin + 70 Gy). However, a current imaging revealed a recurrent tumor and he was admitted to our hospital for radical resection. Computed tomography revealed a disrupted external auditory canal and magnetic resonance imaging indicated a carcinoma equivalent to Pittsburg stage T3. The patient underwent radical STBR without complications. His postoperative course was uneventful. At 2 yr postoperative, his modified Rankin scale score was 1, no recurrence was noted, and his facial nerve function was restored to House-Brackmann Grade IV. This video was reproduced with informed consent from the patient.

Objective To identify the sociodemographic characteristics and risk factors associated with suspected foreign bodies in the ear, nose, throat, airway, and esophagus among Polish children. Study Design Case series with chart review. Setting Tertiary care medical center. Subjects and Methods A retrospective analysis of the medical records of patients hospitalized for a suspected foreign body (FB) between 1998 and 2008 was conducted. Data regarding place of residence, presence of siblings, parents’ educational status, seasonality, psychomotor development, age, and sex were collected and statistically analyzed. Results Of the 1011 patients with suspected foreign body insertion, 849 (84%) had a positive diagnosis. Of the confirmed foreign bodies, 96 were found in the tracheobronchial tree, 142 were found in the esophagus, and 611 were located in the external auditory canals, nasopharyngeal passage, tonsils, auricles, or lips. Sociodemographically, 596 of the children came from urban areas, with a preponderance of males (55%). Objects were removed more frequently in summer and autumn (60%). Children with siblings (53%) predominated. The majority of patients (52%) had parents with an elementary education. Food was the most frequent foreign body in children under 3 years of age. Patients with delayed psychomotor development constituted 1.6% of the analyzed population. Conclusions Being male, 1 to 3 years of age, belonging to an urban family with siblings, and having parents with an elementary education increased the risk of foreign body insertion. Training caregivers about proper nutrition and safety rules when playing with children can reduce the risk of accidents related to foreign body insertion.

Temporal Bone Resection

Object Primary temporal bone malignancy is a rare form of tumor for which the therapeutic strategy remains controversial. In this study, the authors reviewed their experience with radical temporal bone resection (TBR) of such lesions and analyzed the long-term results to provide treatment recommendations. Methods Between 1994 and 2006, 17 patients (10 men and 7 women) underwent total or subtotal TBR for primary temporal bone malignancies. Tumors were graded according to the University of Pittsburgh system. The effects of surgical margins and tumor extensions on patient survival were analyzed using the Kaplan–Meier method. Results All tumors, except 1, were graded T4 (most advanced). Subtotal TBR was performed in 14 patients, and total TBR was performed in 3. The surgical margin was tumor negative in 10 patients and tumor positive in 7. For large tumors extending into the infratemporal fossa or encroaching on the jugular foramen, orbitozygomatic (3 patients) and posterior transjugular (4 patients) approaches were combined with the standard approach, and en bloc resection with a negative margin was achieved in all cases but 1. The follow-up time ranged from 0.3–11.6 years (mean 3.3 years). The 5-year recurrence-free and disease-specific survival rates were 67.5 and 60.1%, respectively. When a negative surgical margin was achieved, the survival rates improved to 100 and 89%, respectively. Conclusions The neurosurgical skull base technique could improve the probability of en bloc resection with a tumor-free margin for extensive temporal bone malignancies, which would cure a subset of patients. The active participation of neurosurgeons would improve patient care in this field.
