Cholesteatoma is one of the common disorders encountered
by the otorhinolaryngologist. However, there are few cases
with an atypical clinical presentation and computed
tomography scan findings which make cholesteatoma
difficult to diagnose. We report a rare case of congenital
mastoid cholesteatoma that presented as a mass
obstructing the external auditory canal. The disease was
successfully treated with a mastoidectomy and
histopathological examination confirmed the diagnosis of
cholesteatoma. Clinicians should consider congenital
mastoid cholesteatoma in the differential diagnosis of
patients with a mass in the external auditory canal. The
diagnosis is likely to be made based on surgical and
histopathological findings.

The combination of vestibular schwannoma (VS) and hemifacial spasm (HFS) caused by a vascular loop is not frequently encountered. Surgical intervention using the retrosigmoid approach may enable the two diseases to be treated simultaneously. A 68-year-old male presented with progressive right HFS. MRI revealed a concurrent vascular loop and 3.2-mm intracanalicular VS. The retrosigmoid approach, together with microvascular decompression, was used to remove VS. Intraoperatively, compression by the vascular loop alone induced HFS although it was not related to VS. This finding is in contrast to the literature reports in which VS has been implicated in HFS. In our patient, when VS was completely removed, HFS immediately disappeared postoperatively.

OBJECTIVES: This case-controlled study aimed to identify the association of tumor necrosis factor (TNF)α-1031 and TNFβ+ 252 gene polymorphisms between chronic rhinosinusitis (CRS) and healthy controls. Another purpose of this study was to investigate the associations of these gene polymorphisms with factors related to CRS. METHODS: All deoxyribonucleic acid (DNA) samples were genotyped for TNFα-1031 and TNFβ+252 genes by mean of polymerase chain reaction (PCR) and restriction fragment length polymorphisms (RFLP). The statistical analysis were carried out using chi-square test or Fisher exact test to determine the associations of these gene polymorphisms in CRS. Multiple logistic regression was performed to evaluate the associations of these gene polymorphisms in CRS and its related risk factors. RESULTS: The genotype and allele frequencies of TNFα-1031 and TNFβ+252 gene did not show any significant associations between CRS and healthy controls. However, a significantly statistical difference of TNFα-1031 was observed in CRS participants with atopy (P-value, 0.045; odds ratio, 3.66) but not in CRS with asthma or aspirin intolerance. CONCLUSION: Although the presence of TNFα-1031 and TNFβ+252 gene polymorphisms did not render any significant associations between CRS and healthy control, this study suggests that TNFα-1031 gene polymorphisms in CRS patients with atopy may be associated with increase susceptibility towards CRS.

Cochlear schwannomas, which are categorized into intracochlear and intravestibulocochlear schwannomas (ICs and IVCs, respectively) are rare and may cause hearing loss (HL). The affected region is invariably correlated with tumor location, which can be detected on magnetic resonance imaging (MRI). We describe the cochleovestibular manifestations of ICs and IVCs. Subjects and Methods: The study included 31 patients with ICs or IVCs. Tumor extent and exact locations were delineated using MRI. Types of HL were subcategorized into the low-to-mid frequency (250 Hz to 1 kHz), mid-to-high frequency (>1 kHz), and all-frequency (universal) HL groups. Results: The tumors involved the entire cochlear turn (two ICs) or extended beyond the cochleae (nine IVCs) in 11 patients, and 20 ICs were located in specific locations as follows: 14 in the basal, 3 in the middle, and 3 in the middle and apical turns. No patient showed tumor invasion of the internal auditory canal or middle ear. The pattern of HL usually reflects the location or extent of a tumor. We observed HL at all frequencies, at low-to-mid frequencies, and at mid-to-high frequencies in 13, 4, and 14 patients, respectively. Dizziness or tinnitus was observed in >50% of patients. Surgical tumor removal was performed in 10 patients, and the remaining patients are undergoing annual monitoring. Conclusions: Cochlear schwannomas may be associated with HL, which may worsen over time and reflect tumor location. Therefore, these lesions should be considered in the differential diagnosis in patients who present with idiopathic, fluctuating, progressive or sudden HL.

Malignant otitis externa (MOE) is a rare and potentially life-threatening disease of the ear and temporal bone. Bilateral simultaneous MOE is extremely rare. Due to bilaterally symmetrical facial nerve palsy, it can easily be missed at the initial presentation, causing delay in management. Here, we report a case of bilateral MOE managed aggressively with regular ear toileting, ear packing with a ribbon gauze soaked with topical antimicrobials, and long-term intravenous and oral antibiotics. The patient showed good improvement in pain control, facial nerve status, and ear findings.
