RESUMEN
Myringoplasty is a procedure which deals on repair of the tympanic membrane. This procedure can be done via postaural, endaural or endomeatal route. Various grafts such as temporalis fascia, vein graft, perichondrium are used. The technique can be categorized as underlay, overlay, interlay or its combination depending on the placement of the graft material. This study was done to compare underlay, overlay and combined technique in terms of the closure of the membrane defect, postoperative complications and over all success rates. Apart from few complications, this study revealed over all success rate was best with combined technique but the difference was not significant statistically when the methods are comparable among them.
RESUMEN
Granular cell tumours are uncommon lesions, although the head and neck region accounts for approximately 50% of all lesions. It is not clear whether or not granular cell tumour is a true neoplasm, a developmental anomaly, or a trauma-induced proliferation. The basic cell of origin is now thought to be neural, although past reports frequently indicated an origin from striated muscle, or less frequently an origin from histiocytes, fibroblasts or pericytes. The tongue and the buccal mucosa are common intraoral sites. The other head and neck site likely to be involved is the larynx. The tumour generally occurs in middle or older aged adults. More than a third of all granular cell tumours occur on the lingual dorsum, usually as a sessile, painless, somewhat firm, immoveable nodule less than 1.5 cm in greatest diameter. Lesions often demonstrate a pallor or a yellowish discolouration and typically have a smooth surface. Histochemical and ultrastructural studies propose the origin of the lesion from Schwann cells, striated muscle, mesenchymal cells, histiocytes and epithelial cells. As most of the granular cell tumours are benign, surgical excision of the lesion is the treatment of choice.
