[Pathologic findings in sinonasal polyposis and predisposing factors]

The aim of this study was to evaluate the pathologic findings in patients with sinonasal polyposis after functional endoscopic sinus surgery, and to assess the relationship between these findings and the predisposing factors of polyposis. This prospective study was conducted from March 2004 to November 2006 among 30 patients. All patients underwent endoscopic sinus surgery after a detailed history and physical examination. The biopsy specimen were evaluated in two groups of eosinophilic and neutrophilic polyposis; then pathologic findings were compared with other findings. Overall, 20 patients [66.67%] were male and 10 [23.33%] were female. The highest frequency was seen in the 50-60-year age group. Allergic rhinitis and septal deviation were the most co-existing conditions. Eosinophilic polyposis was more prevalent than neutrophilic polyposis [18% vs. 12%, respectively, p=0. 04]. Eosinophilic polyposis was more common than neutrophilic type. Males are more frequently affected than females. Allergic diseases and nasal structural abnormalities were the most important factors associated with nasal polyposis

Evaluating serum levels of IgM, IgA, IgG, changes after adenotonsillectomy

Adenoids and tonsils, which are major components of secondary lymphoid organs, appear to function as the host's first line of defense against exogenous microorganisms. The purpose of this study was to investigate possible impacts of Adenotonsillectomy in serum levels of IgA, IgG, 1gM as indicators of humoral immunity, but there is a controversy about immunologic effect of tonsillectomy and adenoidectomy. Pre and post operative serum samples were collected from 40 patients [7-11 years old] referred for adenotonsillectomy. Serum samples were analyzed, using Radial Immune Diffusion [RID] method to determine levels of IgA, IgG, IgM, before and 3 week after surgery. The level of IgA and IgM were reduced in post operative period. But this was not statistically significant. However, it was found that the level of IgG was reduced in the post operative period and this reduction was statistically significant [P<0.01]. The results of this study indicate that adenotonsillectomy had not a significant effect on two major parts of humoral immunity [IgA and IgM] but it reduced IgG levels

Study of effect of resection of cephalic portion of nasal alar cartilage on nasal tip rotation

One of the most common techniques of nasal tip surgery in rhinoplasty is conservative resection of cephalic portion of nasal alar cartilage; although, there is a controversy about its effectiveness on nasal tip rotation in textbooks and articles. Therefore, in this research, we have studied the effect of conservative resection of cephalic portion of alar cartilage on nasal tip rotation. 35 patients were selected from the patients who were candidates for septoplasty, after getting their agreement. In surgery we performed conservative resection of cephalic portion of alar cartilage. Nasolabial angles were calculated, using the lateral photographs of the patients before and six monthes after surgery. The means of these angles were analyzed with t-paired test. The means and standard deviations of nasolabial angles before and six months after surgery were 91.49 +/- 7.35 and 91.57 +/- 7.04, respectively. Calculated P-value was 0.52. There was no meaningful difference between means of nasolabial angles before and six months after surgery [P-value was greater than 0.05]. Therefore, in this research we concluded that conservative resection of cephalic portion of alar cartilage has no effect on nasal tip rotation

Evaluatin and comparison of the complications rate and the number of epley and semont maneuvers needed in treatment of benign positional vertigo

Introduction: Benign positional vertig in one of the most common causes of patient referrence to the otolaryngologist. Maneuver therapy [Epley and Semont] was effective and with few complications. The object of this study was evaluation and comparison of the complications and the number of maneuver needed for recovery in BPPV patients

Methods: Center from April 2001 to September 2002 in 130 patients with The study performed in Ayatollah Kashani Medical confirmed diagnosis of posterior canal Benign positional vertigo with history taking and hall pick testing . The patients were randomely placed in two groups of 65 cases. For these groups respectively Epley and Semont maneuver performed by researcher and during a three months of follow up, each week the patients evaluated for recovery by performing hall pick maneuver and history taking

Results: [P < 0.05]. Theses two groups were matched for gender and age The recovery rate of Epley and Semont group at the end of follow up Were respectively [93.84% - 76.92%] [P = 0.01]. 0.082]. The complicaion rate were respectively [4.61% - 0%][P = The mean number of maneuver implemented were respectively [1.93 +/- 1.09 and 2.1 +/- 0.88] [P = 0.09]

Conclusion: This study showed that both maneuvers were effective, with more efficacy of Epley. These maneuvers have no meaning full difference in complication rate / and the number of maneuvers needed for recovery

[ case report of paranasal sinus Ewing's sarcoma. Al-Zuhra Hospital, Isfahan University of medical Siceences Iran]

Sarcomas, especially Ewing's sarcomas, are very rare in nose and paranasal sinuses [PNS]. Experiences about diagnosis and treatment of ewing's sarcoma in this region are very limited; and it seems, that a multidisciplinary team approach [surgical, chemo-radiotherapy] in management of this malignancy is needed. In this article, we have reported a 16-Year old boy with symptoms and signs of nose and PNS tumor [malignancy]. A tumor [in the right nostril and maxillo-ethmoidal sinuses] was resected by means of a facial degloving approach with preservation of orbital contents; and according to the histopathological report, the patient was referred to an oncology and chemo-radiotherapy center for further control
