    面神经神经鞘瘤很少见,良性,缓慢生长的肿瘤,可以发生在面神经的任何部分,尽管71%的病例是颞内。手术切除可导致面神经损伤。复活后的面部功能恢复通常不比House-Brackmann(HB)III级更好。因此,对于具有良好面部功能(HBI级或II级)的颞内面神经神经鞘瘤(IFNSs)的病例,定期磁共振成像观察是管理的主要手段。这里,我们介绍了一个具有正常面部功能的大型IFNS病例,其中肿块完全阻塞了外耳道。闭塞导致鳞状碎片积聚,可能导致胆脂瘤.面对这种治疗困境,我们在患者知情同意的情况下选择手术切除。剥离术后面部功能正常。随访2年无术后面瘫或复发。我们描述了这种情况的诊断和治疗过程的经验,并讨论保留面神经完整性的肿瘤全切除的可能性。
    Facial nerve schwannomas are rare, benign, slow-growing tumors that can occur in any segment of the facial nerve, although 71% of cases are intratemporal. Surgical resection can lead to facial nerve injury. Facial function recovery after reanimation is usually not better than House-Brackmann (HB) grade III. Thus, for cases of intratemporal facial nerve schwannomas (IFNSs) with favorable facial function (HB grade I or II), observation by periodic magnetic resonance imaging is the mainstay of management. Here, we present a case of a large IFNS with normal facial function in which the mass fully occluded the external auditory canal. The occlusion caused squamous debris to accumulate, potentially leading to cholesteatoma. Faced with this therapeutic dilemma, we chose surgical resection with the patient\'s informed consent. Stripping surgery was achieved with normal postoperative facial function. There was no postoperative facial paralysis or recurrence at 2-year follow-up. We describe the experience of diagnosis and treatment process for this case, and discuss the possibility of total resection of the tumor with preserving the integrity of facial nerve.

    Most cases of acute otitis media resolve with antibiotics and imaging is not required. When treatment fails or a complication is suspected, imaging plays a crucial role. Since the introduction of antibiotic treatment, the complication rate has decreased dramatically. Nevertheless, given the critical clinical relevance of complications, the importance of early diagnosis is vital. Our objective was to review the clinical and radiological features of acute otitis media and its complications. They were classified based on their location, as intratemporal or intracranial. Imaging makes it possible to diagnose the complications of acute otitis media and to institute appropriate treatment. Computed tomography is the initial technique of choice and, in most cases, the ultimate. Magnetic resonance is useful for evaluating the inner ear and when accurate evaluation of disease extent or better characterization of intracranial complications is required.

    Facial nerve schwannoma is the most common facial nerve tumor, but its therapeutic strategy remains debated. The aim of this study is to analyze the facial nerve function and the hearing outcomes after surgery or wait-and-scan policy in a facial nerve schwannoma series. A monocentric retrospective review of medical charts of patients followed for an intratemporal facial nerve schwannoma between 1988 and 2013 was performed. Twenty-two patients were included. Data were extracted pertaining to the following variables: patient demographics, tumor localization, clinical and imaging features, facial nerve function and hearing levels, and details of surgical intervention. The majority of tumors were located at the geniculate ganglion. Initial symptoms were mainly facial palsy and hearing loss. The average follow-up was 4.8 ± 4.5 years. Nineteen patients underwent surgery, and three patients were observed. After surgery, 11 patients had a stable or improved facial nerve function (57.9 %), and 8 patients had a worsened facial nerve function (42.1 %). Facial nerve function was in the majority of cases a HB grade III, depending on surgical strategy. No patient presented a postoperative HB grade V or VI. Regarding the hearing, it remained stable after surgery in 52.6 % of cases, and improved in 10.5 % of cases. Among monitored patients, facial nerve function and hearing remained stable. Surgery for facial nerve schwannoma is a safe and effective option in the treatment of these tumors.

    OBJECTIVE: To review all cases intratemporal and intracranial complications of acute otitis media (AOM) in infants and children from 1998 to 2013.
    METHODS: Retrospective chart review of 109 consecutive patients admitted for complications of AOM during a 15-year period at a tertiary-care children\'s hospital. The main outcomes are: (1) complications of AOM, (2) bacteriology, (3) management strategies.
    RESULTS: In our population, complications included mastoiditis (86.1%), subperiosteal abscess (38%), facial nerve palsy (16.7%), sigmoid sinus thrombosis (8.3%) and epidural abscess (7.4%). Other complications included post-auricular cellulitis, otic hydrocephalus and elevated intracranial pressure, internal jugular thrombosis, cranial nerve VI palsy and Gradenigo\'s syndrome, labyrinthine fistula, sensorineural hearing loss, and cerebellar infarct. Sixty-one patients (56%) received antibiotics prior to presentation. Cultures revealed Streptococcus pneumoniae in 36 patients (33.3%), other bacteria in 30 patients (27.8%), and \"no growth\" in 33 patients (30.5%). Nine patients (8.3%) did not undergo culture. Of the patients with S. pneumoniae, 20 cultures (55%) were found to be multidrug-resistant. Eleven patients (10.2%) were treated non-surgically, 31 (31%) were treated with myringotomy and intravenous antibiotics. Forty patients (97.5%) presenting with subperiosteal abscess required mastoid surgery. Thirteen of 18 (72.2%) patients with facial paralysis had full recovery. Eight of 10 (80%) patients with epidural abscess empyema required mastoid surgery and incision and drainage of the abscess.
    CONCLUSIONS: Complications of AOM are uncommon, yet continue to have potentially serious consequences. The bacteriology in this population reveals an increasing trend of multi-drug resistant S. pneumoniae as the causative organism.

    An intimate knowledge of facial nerve anatomy is critical to avoid its inadvertent injury during rhytidectomy, parotidectomy, maxillofacial fracture reduction, and almost any surgery of the head and neck. Injury to the frontal and marginal mandibular branches of the facial nerve in particular can lead to obvious clinical deficits, and areas where these nerves are particularly susceptible to injury have been designated danger zones by previous authors. Assessment of facial nerve function is not limited to its extratemporal anatomy, however, as many clinical deficits originate within its intratemporal and intracranial components. Similarly, the facial nerve cannot be considered an exclusively motor nerve given its contributions to taste, auricular sensation, sympathetic input to the middle meningeal artery, and parasympathetic innervation to the lacrimal, submandibular, and sublingual glands. The constellation of deficits resulting from facial nerve injury is correlated with its complex anatomy to help establish the level of injury, predict recovery, and guide surgical management.
