ABSTRACT
The use of anticoagulants, for whatever indication, may carry a high risk of hematoma formation following surgery. Obstructive uropathy is a very rare but possible example of complication secondary to an extensive pelvic hematoma. We describe a case of a patient with rheumatic heart disease and aortic valve replacement, who developed a massive postoperative pelvic hematoma following bilateral tubal ligation, resulting in bilateral ureteric obstructions. This was treated with bilateral ureteric stent through cystoscopy

This study was directed to evaluate the ultrasonographic examination of the paranasal sinuses, compared with conventional plain radiography after confirming the diagnosis endoscopically. Computerized tomography was the standard diagnostic tool. The study comprised 20 patients [13 males and 7 females], attending the Ear, Nose and Throat Department of Assiut University Hospital. The majority of the patients were in the 2nd decade of life. The most common symptoms were post nasal discharge, nasal obstruction and headache. Conventional radiographic study was more sensitive than ultrasonography in disease detection [88.88% versus 65.59%], while ultrasound [US] and endoscopy were nearly of the same sensitivity. Ultrasound was found to have higher specificity value in the detection of mucosal thickening and polyp formation, but less specific for fluid level detection. Ultrasonography may be considered as a specific diagnostic tool of the sinusitis

This study aimed to investigate the mechanism of obstructive sleep apnea syndrome [OSAS] in patients with retrognathia resulting from long-standing temporomandibular joint [TMJ] ankylosis to establish their correct management. Six patients suffering from retrognathia caused by long-standing TMJ ankylosis were subjected to polysomnography. These patients were offered mandibular or maxillomandibular and hyoid advancement. In addition, vulopalatopharyngeoplasty was done in one patient. All patients were clinically, radiologically, polysomnographically and endoscopically evaluated before and after surgery. The clinical preoperative evaluation proved that three patients were mainly presented with snoring and sleep apnea, while the remaining three patients were mainly presented with facial deformity, limitation of mouth opening or both. All patients were proved to have snoring and repetitive apneic attacks, but only three had excessive day somnolence. They also had facial deformity and limitation of mouth opening. Cephalometric analysis proved the presence of mandibular retrusion, shortening of the lower face height, narrowing of the posterior airway space and lengthening of the soft palate and uvula. Endoscopic evaluation showed that such patients had narrowing of the upper airway at three levels [retropalatal, the vertical space between the soft palate and tongue and the retroglossal airway], except one patient who had wide retropalatal airway. A collapse occurs due to backward and upward displacement of the tongue, which does not only cause airway narrowing at the retroglossal but also at the retropalatal airway. This creates a collapsing segment that extends from below the base of the tongue as high as the soft palate. All patients had surgical planning that included presurgical orthodontic evaluation, prediction tracing and model surgery with preparation of occlusal splints. All patients had mandibular advancement that was accompanied by maxillary advancement in three patients. Advancement genioplasty was done in two of them. One patient needed uvulopalatoplasty, in addition to the advancement procedure. According to postoperative polysomnography, five patients had a successful result and one patient had worsening of sleep apnea. Widening of the airway was demonstrated by cephalometric and endoscopic evaluation, except that patient with worsening of the sleep apnea that had more bulging of the lateral pharyngeal walls during endoscopic examination. The complications included infection, salivary fistula, recurrence of ankylosis, injury of the marginal branch of the facial nerve, malocclusion and worsening of sleep apnea

Fine needle aspiration biopsy [FNA] of superficial and deep-seated lesions of the head and neck has been used extensively with high sensitivity and specificity. Several articles have stressed the role of computed tomography in detecting and staging head and neck tumors. FNA has been paired with imaging guided localization for the cytologic assessment of lesions in the parapharyngeal space. This work presented a series of 30 CT-guided percutaneous biopsies performed between January 1997 and January 2000 at Assiut University Hospital. The age of the patients ranged from 13 to 60 years [mean 37] with 21 males and 9 females. Analysis of the results showed 8 inflammatory lesions, 12 benign tumors and 10 malignant neoplasms. Correlation with histopathology of true-cut needle or incisional biopsy showed a diagnostic accuracy of 88.0% but certain lesions could not be diagnosed by this procedure. FNA can replace incisional biopsy, which may be hazardous in this area. Surgery can be avoided for inflammatory lesions

The study included 30 patients with middle ear cholesteatoma; the specimens were obtained from patients undergoing ear surgery for cholesteatoma. The examination also included seven samples of normal external auditory canal skin, five samples of the middle ear mucosa adjacent to cholesteatoma. The specimens were processed for both light and transmission electron microscopy. Flattening of the cells and morphological characteristics resemble that of the external canal skin was found. The mucosa adjacent to the cholesteatoma was found diseased with impaired mucociliary function. The ultrastructural arrangement of the basement membrane is like that of skin. The study showed the role of retraction pockets in cholesteatoma development. Because of the inflammatory reaction in the mucosa adjacent to cholesteatoma, thorough irrigation during surgery and antimicrobial therapy after surgery are warranted

The nasal lacrimal apparatus is intimately related to the lateral nasal wall and may readily be approached using an endoscopic technique. Endoscopic laser assisted lacrimal surgery is a new technology, which was applied in our patients. The studied group included 10 patients [7 females and 3 males] ranging in age from 6 to 66 years. The main symptoms were epiphora and discharge. The main site of obstruction was at the nasolacrimal duct [determined by the dye test and dacryocystography]. Laser was applied under general anesthesia to evaporate the nasal mucosa opposite the lacrimal sac, ablate the under lying bone and excise the medial wall of the lacrimal sac. The patients were followed up for one year. The patients maintained a patent opening and had no recurrence of epiphora. The technique avoids a cutaneous scat and causes less surgical trauma and bleeding without major complications

The effect of nasal packing and tonsillectomy on the middle ear pressure was investigated. Forty% of patients with bilateral anterior nasal packs had a negative pressure corresponding to type C1 and C2. However, the incidence of negative middle ear pressure with posterior packing was high [80%]. 53% of tonsillectomy patients developed negative middle ear pressure. No patients in this series developed middle ear effusion probably because the tubal dysfunction was partial and of short duration. Patients after tonsillectomy and nasal packing were advised to be examined otologically to exclude persistent negative middle ear pressure
