Nerve Paresis

Sporadic vestibular schwannoma (VS) is the commonest tumour of the cerebellopontine angle and comprise 6–8% of all intracranial tumours. The incidence varies between 12 and 20 cases per million inhabitants and years in different reports; a large minority of these tumours grow during follow-up. Treatment options include wait and scan, microsurgery, radiosurgery, and radiotherapy. Micro- and radiosurgery are well validated to offer long-term tumour control, but patients may suffer from hearing deficit and facial nerve paresis. Unexpectedly, long-term life quality is more affected by vertigo and headaches. Other cranial nerve schwannomas cause symptoms depending on the affected nerves and respond to the same therapies when treatment is indicated.

Cavernous angiomas of the internal auditory canal are rare lesions. The authors present a case of a 29-year-old lady with multiple infratentorial cavernous angiomas, whose sister had previously undergone surgery for a similar supratentorial lesion. She initially presented with an acute brainstem haematoma, secondary to a pontine cavernous angioma. Three years later she developed progressive right-sided sensorineural hearing loss and facial nerve paresis due to an internal auditory canal lesion. This was removed via the translabyrinthine approach and was found to be a cavernous angioma. This report underlines the multiple and dynamic nature of familial cavernous angiomas, as well as the importance of follow up to determine whether new symptoms are due to the enlargement of known angiomas or the development of new ones. As far as the authors are aware, this is the first report describing a cavernous angioma of the internal auditory canal in the context of familial and multiple infratentorial angiomas.

<p class="abstract"><strong>Background:</strong> The pleomorphic adenoma comprises 45-60% of all salivary gland tumors most often in parotid gland up to 80%.

Background The surgical management of benign lesions of the parotid gland is focused on the complete removal of the lesion, minimizing the chances of recurrence and to preserve facial nerve function. There is a relative paucity of literature regarding the post-operative complications of the surgical procedures for benign parotid lesions. The aim of this study is to evaluate the post- operative complications of a limited surgical procedure, namely partial superficial parotidectomy. Material and Method This retrospective cohort study included all parotid surgeries performed for benign parotid pathology from January 2008 to December 2018. The patient’s demographic data, presenting symptoms, type of surgery performed, complications, presence of post operative facial nerve paralysis and grade, histopathology type and follow up period were collected from hospital records of Al Shifa system. The mean follow-up time was 12.5 months. Results The study yielded a total of 125 partial superficial parotidectomies performed on 123 patients with a mean age of 44.5 years (range 8-87 years). Pleomorphic adenoma (n= 68, 54.4%) and Warthins tumor (n=32, 25.6%), were the most common neoplastic lesions. Non-neoplastic lesions were 18 (14.4%). Temporary facial nerve weakness occurred in 11 patients (8.8%). All cases of facial nerve weakness improved within three months post-operatively. The rate of salivary fistula and sialocele were 5.5% and 1.5% respectively. One patient who had histologically proven pleomorphic adenoma had recurrence of tumor (0.8%). Conclusion Partial superficial parotidectomy was associated with low incidence of facial nerve dysfunction which was mostly transient, and no permanent facial nerve dysfunction was reported. Other complications like sialocele, salivary fistula and Frey’s syndrome were reported at lower rates than the reported rates in the literature for the conventional superficial parotidectomy. The findings support partial superficial parotidectomy approach for the treatment of benign parotid pathology, which entails less extensive resection of parotid parenchyma and less extensive dissection of facial nerve branches thereby minimizing the risk of post-operative complications.

Canal Wall Down Mastoidectomy

This study reviewed 299 patients who underwent canal wall down mastoidectomy between April 1997 toApril 2000 in the Department of Ear, Nose & Throat (ENT), Tribhuvan University Teaching Hospital,Maharajgunj, Kathmandu. Sixty four patients had complications of chronic suppurative otitis mediaatticoantral type and five patients did not come for follow up. Out of remaining 230 patients, modifiedradical mastoidectomy was the commonest type of mastoid surgery which was done in 202 (87.83%)patients. Two hundred twenty four (96.39%) patients had a dry cavity. Nine (3.91%) patients developedwound infection, the commonest postoperative complication seen. Although 6 (2.61%) patients developedfacial nerve paresis/paralysis, 5 (2.18%) patients had total recovery of the facial nerve function and onlyone patient had persistent facial nerve palsy. Intracranial complications were seen in 3 (1.30% ) patientsand recurrence of disease in 2 (0.87%) patients. One patient died of septicemia. Proper aseptic precautionduring and after surgery and adequate knowledge of surgical landmarks is necessary to reducecomplications of surgery.

Main Components

Scanning microscopy was used to study the surface of human gallstones and the surface of fractures. The specimens were obtained by operation, washed with water, dried at room temperature and shadowcasted with carbon and aluminum. Most of the specimens belong to patients from a series of X-ray follow-up study, examined during the last twenty years. So it was possible to evaluate approximately the age of these gallstones and to get information on the intensity of growing and solving.Cholesterol, a group of bile pigment substances and different salts of calcium, are the main components of human gallstones. By X-ray diffraction technique, infra-red spectroscopy and by chemical analysis it was demonstrated that all three components can be found in any gallstone. In the presence of water cholesterol crystallizes in pane-like plates of the triclinic crystal system.
