    Case Report

    We present two clinical cases to illustrate that we are currently in a position to accurately locate the site of the lesion in vestibular system diseases thanks to advances in complementary tests.

    The solitary fibrous tumor (SFT) is a mesenchymal, spindle cell neoplasm. It was originally described as a tumor of the mesothelial tissue of the pleura. However, numerous extrathoracic sites have been described recently. Nowadays,is accepted that the SFT has a mesenchymal origin and that the extrathoracic localization is at least as common as the pleural disease.
    The SFT in the nasal cavity and perinasal sinuses is extremely rare and only 25 case-reports have been described in the literature.
    We present a case of a male patient with a SFT of the nasal cavity and provide a review of the literature.

    Case history: A 41-year-old patient suffered from hearing loss and tinnitus on his right ear, following a car accident with airbag deployment. Hearing loss recovered partially, Tinnitus and difficulties in speech discrimination sustained.
    Findings: Audiometry showed typical high frequency hearing loss (40 dB) and tonal tinnitus (8kHz). However, DPOAE and ABR-potentials (Wave III and V) were completely normal, but there was no detectable CAP in ECochG.
    Discussion: These findings indicate a recovery of the initial hair cell damage, whereas the synaptic transformation remains reduced and a slight hearing loss persists. This phenomena has been described as hidden hearing loss in the newer literature.
    Conclusion: Noise trauma initially results in hair cell damage, but after recovery hearing loss can persist that can be due to synaptic lesions in the first neuron.

    Laryngeal chondromas are very uncommon cartilaginous benign tumors of the larynx. Although, total laryngectomy is reserved for high-grade laryngeal chondrosarcomas, some studies indicate that conservative approach in typical chondrosarcoma has increased the occurrence of local recurrence. Two cases of cricoid chondrosarcoma and chondroma is reported in young adult men with obstructing the laryngeal lumen without vocal cord paralysis. The chondroma and chondrosarcoma were totally excised through a laryngo-fissure approach to protect laryngeal function. Minimal invasive operation through a laryngo-fissure approach may yield a proper laryngeal function without any recurrence of the chondroma and chondrosarcoma for more than 2 years after operation time.

    Objectives: The objectives are to develop the Hearing Handicap Inventory for Elderly Thai version (HHIE-Thai), to validate its content and construct validity, and to assess the test-retest reliability.
    Design: The HHIE was translated into Thai language and was tested for content and construct validity. Ten subjects were tested by self-administration and interview. The test-retest reliability was conducted in 50 hearing impaired elderly adults tested one month apart by interview without any hearing rehabilitation.
    Results: The Pearson's product-moment correlation of the total score was r = 0.90 (95% CI 0.63 - 0.98, p< 0.001), the social items r= 0.90 (95% CI 0.73 - 0.98, p< 0.001) and the emotional items r= 0.93 (95% CI 0.63 - 0.98, p< 0.001). Fifty subjects mean age 74.12 ± 7.66 years, 31 males (62%) 19 females (38%).Most subjects had primary school education and lower income. The test-retest reliability Cronbach's alpha of 0.82 for the total score and intra-class correlation (ICC) was 0.63. Each of the 25 items had high correlation alpha ranging from 0.81 to 0.83.
    Conclusions: The Hearing Handicap Inventory for Elderly Thai version (HHIE-Thai) has a good internal consistency, good construct validity and test-retest reliability. It can be used either by self-administration in literate subjects or by face to face interview in less literate subjects.
