Abstract
Inverted papilloma is an uncommon benign neoplasm originating from lateral nasal wall. It commonly invades paranasal sinuses and sometimes invasion to orbit and intracranial structures are seen. There are many surgical methods for its treatment, one of them is endoscopic transnasal approach.
Materials and Methods: Between 1997 and 2001, 11 patients with this tumor were operated in Amiralam hospital in Tehran and Shahid Rahnemun in Yazd. Nine patients were operated by endoscopic transnasal route and two patients by combined Caldwell-luc and endoscopic transnasal routes.
Results: Tumors were on the right side in 3 patients, on the left side in 7 patients, and bilateral in one patient. There were no intracranial or orbital extensions. No pathologic report of malignancy was made. Surgical technique included complete tumor resection, anterior and posterior ethomidectomies, sphenoidectomy, frontal recess tumor resection and wide maxillary antrostomy, in cases in whom tumor was attached to lamina papyracea, the lamina was removed without any manipulation to orbital periosteum. Mean follow-up time was 29.8 months. There was no recurrence in 82% of cases. Tumor recurred in 18% of cases. No complications were seen.
Conclusion: Although the standard treatment for this tumor is medial maxillectomy but endoscopic resection is an effective method in surgery of this tumor. It seems that if tumor does not extend to areas unreachable by endoscopic surgery, due to lower morbidity and excellent visualization of tumor, this method is preferable.

Abstract
Background and Aim: It seems that diabetes mellitus affects hearing system by several mechanisms including microangiopathy ,sorbitol deposition and glycosilation ,dealing to progressive bilateral sensorineural hearing loss which is related duration of diabetes.
Materials and Methods: This is a descriptive cross-sectional study performed on 300 patients with type 2 diabetes mellitus aged 30 to 50 years and a control group of 300 persons matched regarding age and gender .The cases were selected randomly and they were assessed by a quastionaire before performing audiogram. The exclusion criteria were conductive hearing loss sensorineural hearing loss with any other cause and other metabolic diseases .Audiometric test battery consisting of pure tone audiogram (PTA) and impedance were perfumed on both case and control groups.
Reasults: In this study the hearing threshold in low and high frequencies in case group was higher than control group. In different age groups, the mean high and low frequencies hearing threshold in case group was higher than control groups. Based on duration of diabetes , the mean hearing threshold in the group with 8 to 18 years duration of diabetes was higher than the other two groups with 1 to 3 years and 4 to 7 years diabetes duration. The hearing level of hypertensive and normotensive diabetic patients were not significantly different. The mean hearing threshold was not significantly different between male and female diabetic patients.
Conclusion: In general, diabetic patients have a poorer hearing compared with normal population and there is a significant relationship between duration of diabetes and incidence of sensorineural learning loss.

Abstract
Background: Traumatic tympanic membrane (TM) perforation is a common injury of the ear with a high rate of spontaneous healing if the patients strictly adhere to water precautions. The purpose of this study was to determine the factors involved in the spontaneous healing of traumatic TM perforations in order to ascertain the best treatment plan including observation, paper patch and finally surgery.
Methods: In this correlative–descriptive study, we recorded the outcome of each patient with three-month follow up. Included in this study were a total of 202 forensic medicine patients from the Dept. of Otolaryngology Head & Neck Surgery at the Yazd University of Medical Sciences, Yazd, Iran. All patients included in this study had traumatic TM perforation. Based on otoscopic examination, the perforations were classified as pinpoint or large. All patients received an audiometry exam and were followed for three months. The data was collected using a special form and analyzed by chi-square test, Fisher exact test and ANOVA.
Results: This study consisted of 118 male and 84 female patients with a mean age of 23.6 years (6-48 years). The types of trauma included compression injury (104 patients), instrumental injury (59 patients), burn–slag injury (2 patients) and blast injury (1 patient). One hundred and eighty patients had pinpoint TM perforations, 99.4% of which healed spontaneously by the second month, and 32 patients had large TM perforations, 50% of which healed spontaneously by the second month. During the first month, 87.3% of the patients observing water precautions had healed, however the healing rate was only 5.6% in patients not adhering to water precautions, who suffered from otorrhea. Therefore, during this study, 185 (91.58%) patients had spontaneous healing by two months and only 6 patients of remaining 17 patients healed with paper patch. The mean hearing loss at 500, 1000 and 2000 Hz was 10.55 dB (5-30 dB).
Conclusion: In our experience, patients with traumatic TM perforations have higher spontaneous healing rate when observing water precautions. Furthermore, we recommend observation and paper patching for three months before attempting any surgical intervention in such patients.

Abstract
Background: In rhinoplasty, periorbital edema and ecchymosis is due to soft tissue trauma and small vessel injury with subsequent exudation and bleeding. The main purpose of this study is to determine the effect of dexamethasone in reducing periorbital edema and ecchymosis and intraoperative bleeding in rhinoplasty patients.
Methods: This double-blind study included 90 patients who underwent rhinoplasty from October 2004 to March 2005. In group A, 8 mg of intravenous dexamethasone was administered only preoperatively. In group B, 8 mg of dexamethasone was administered preoperatively and continued every 8 hours postoperatively. Group C, the control group, received no dexamethasone.
Results: The degree of upper lid edema in groups A and B was significantly less than that of group C. During the first and second day the severity of upper lid edema in group B was less than that of group A, but the difference was not significant. The degree of lower lid edema during the first and second days in groups A and B was significantly less than that of group C, although it was identical in all groups during the fifth and seventh days. The degree of upper lid ecchymosis during the first and fifth days in group C was significantly more than that of groups A and B, but it was similar on the seventh day in all groups. The degree of lower lid ecchymosis on the first day in groups A and B was significantly less than that of group C however, it was similar in all groups during the second, fifth and seventh days. The volume of intraoperative bleeding in the three groups was similar. The mean period of recovery (12 days) was comparable in all groups.
Conclusions: Dexamethasone administration leads to the reduction of upper lid edema, ecchymosis and lower lid edema during the first and second postoperative days, and reduction of lower lid ecchymosis on the first postoperative day.
