ABSTRACT
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. 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 and 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. 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]. 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

The presence of anatomic variations of paranasal sinuses must be noted in order to attain a full understanding and accurate diagnosis of chronic sinusitis. The frequency of anatomic variations in chronic sinusitis is different in various studies. The purpose of this study is to assess the frequency of anatomic variations in chronic sinusitis patients admitted to Otolaryngology ward of Shahid Sadoughi hospital in the year 2004 and underwent functional endoscopic sinus surgery. Based on preoperative paranasal sinus CT scan the extent of patients diseases on a scale of 0-IV and the presence of anatomic variations was determined. A total of 120 patients were included. We found Agger Nasi cells in 43[36%], Haller cells in 5 [4.17%] conchae bullosa in 15[12.5%], paradoxical middle turbinate in 2 [1.67%] and septal deviation in 54 patients [45%]. Patients with Agger Nasi [P value: 0.015] and conchae bullosa [P Value: 0.024] demonstrated significantly higher scores on sinus CT scan compared with patients without Agger Nasi cells and conchae bullosa respectively. Three months postoperatively we observed significantly less resolution of nasal congestion [P Value: 0.006] in patients with septal deviation than patients without it. No significant difference was seen among patients with and without other anatomic variations with regard to resolution of rhinorrhea and nasal congestion three months postoperatively
