RESUMEN
The aim of this study is to evaluate the long-term results of endoscopic sinus surgery in the treatment of antrochoanal polyps and the role of extending the middle meatal antrostomy on the expense of the inferior meatus in providing wide exposure and accessibility within the maxillary sinus to ensure complete removal of its antral portion. Thirty-six patients were reviewed. Two groups were identified: Group A including patients with antrochoanal polyps that were resected endoscopically through a classical wide middle meatal antrostomy and Group B which included those who underwent endoscopic removal via an extension of the antrostomy inferiorly through submucosal resection of the lateral bony skeleton of the inferior meatus. There were 13 female and 23 male patients with a mean age of 28 ± 9.4 years. The mean follow-up period was 20.4 ± 6.7 months. Six patients were recurrent after previous endoscopic surgery. Group A included 17 patients and the remaining 19 patients were assigned to Group B. Two patients from Group A developed symptomatic recurrence and were cured with revision extended antrostomy. Three patients showed endoscopic evidence of a developing cystic lesion within the maxillary sinus that was punctured through the wide antrostomy. Endoscopic resection is considered the main treatment modality of antrochoanal polyps. Modification of the technique through removal of the lateral bony skeleton of the inferior meatus with downward displacement of the inferior turbinate provided accessibility to the inferior and prelacrimal recesses of the maxillary sinus.

OBJECTIVE: Contradictory results have been reported regarding Helicobacter pylori (H. pylori) detection in adenotonsillar tissue. The aims of this study were to investigate whether adenotonsillar tissue of symptomatic children with chronic adenotonsillitis harbors the H. pylori organism, using two biopsy-based invasive methods namely; rapid urease test (RUT) and polymerase chain reaction (PCR) as well as blood serology and to compare the results obtained from each of these methods to the "gold standard". METHODS: This prospective clinical study was carried out on 20 children aged between 2 and 10 years scheduled for tonsillectomy +/- adenoidectomy in a tertiary referral center. Exclusion criteria included: use of antacids, H(2) blockers or antibiotics during the previous month before surgery and adenotonsillectomy for obstructive sleep apnea. Core biopsy samples from resected adenotonsillar tissue was tested for H. pylori detection using both RUT and PCR assay for the ureC gene. Preoperative patient venous blood samples were also tested for H. pylori IgG antibodies. As a "gold standard", examined tissue was considered to be H. pylori infected if the two biopsy specimen-based methods (RUT and PCR) yielded positive results. RESULTS: Thirty adenotonsillectomy specimens were tested (20 tonsils and 10 adenoids). RUT was positive in 16 (53.3%) specimens (12 tonsils and 4 adenoids). According to the "gold standard", 11/16 were considered false-positive, yielding this test sensitivity 100% and specificity 56%. The ureC gene sequence was detected by PCR in 5 (16.6%) specimens (3 tonsils and 2 adenoids), all of which were also positive by RUT, thus were considered H. pylori infected. Accordingly, PCR had a 100% sensitivity and specificity. Serology testing was positive for H. pylori IgG antibodies in 4/20 patients (20%), only two of them were found to have H. pylori infected adenotonsillar tissue. CONCLUSIONS: Based on our findings it seems that adenotonsillar tissue may constitute an extra-gastric reservoir for H. pylori in symptomatic children with chronic adenotonsillitis. RUT was found to be of less accuracy than PCR in H. pylori detection in an extra-gastric location, thus results of previous studies using this test alone for detection of oral H. pylori should be treated with caution.

CONCLUSION: Rhinoscleroma is a chronic, specific, granuloma of the nose and other parts of the respiratory system. The disease is endemic in Egypt and many other countries. The causative organism is Klebsiella rhinoscleromatis bacillus, proved by fulfilling Koch's postulates. The mode of infection is not known and its worldwide irregular geographical distribution is not understood. Lines of treatment are unsatisfactory and a tendency for recurrence is the rule. OBJECTIVES: Our aim was to study the clinical presentation, microbiology, pathological staging, follow-up, and lines of treatment of new rhinoscleroma patients admitted or seen at Alexandria Main University Hospital from January 1999 until January 2009. METHODS: Demographic data and the results of clinical, bacteriological, and histological examinations were reviewed. Medical and surgical treatments were evaluated. Follow-up as regards the results of treatment and incidence of recurrence was assessed. RESULTS: Fifty-six patients were included in the study. There were 26 males and 30 females, and 85% of patients presented in the third and fourth decades of life. The nose was affected in 100% of patients. Other regions affected were the nasopharynx in 13 patients, palate in 7 patients, skin in 2 patients, larynx in 3 patients, trachea in 17 patients, nasolacrimal duct in 2 patients, and premaxilla in 1 patient. No lymph node affection was reported. Klebsiella rhinoscleromatis strain III was isolated from 100% of patients. Antibiotics used were a combination of trimethoprim-sulfamethoxazole 400 mg and rifampicin 300 mg twice daily for 3 months. Since 2003, this was replaced by ciprofloxacin 500 mg twice daily for 3 months. Surgical procedures performed were removal of nasal granulations, bronchoscopic dilatation, bipolar coagulation of skin lesions, tracheostomy, and repair of pharyngeal stenosis. Results were disappointing, as a large number of patients did not attend for follow-up. A high incidence of recurrence was found, reaching up to 25% within 10 years.

OBJECTIVE: To evaluate the use of the temporalis myofascial flap in primary cranial base reconstruction following surgical tumor ablation and to explain technical issues, potential complications, and donor site consequences along with their management. DESIGN: Retrospective case series. SETTING: Tertiary referral center. PARTICIPANTS: Forty-one consecutive patients receiving primary temporalis myofascial flap reconstructions following cranial base tumor resections in a 4-year period. MAIN OUTCOME MEASURES: Flap survival, postoperative complications, and donor site morbidity. RESULTS: Patients included 37 males and 4 females ranging in age from 10 to 65 years. Two patients received preoperative and 18 postoperative radiation therapy. Patient follow-up ranged from 4 to 39 months. The whole temporalis muscle was used in 26 patients (63.4%) and only part of a coronally split muscle was used in 15 patients (36.6%). Nine patients had primary donor site reconstruction using a Medpor((R)) (Porex Surgical, Inc., Newnan, GA) temporal fossa implant; these had excellent aesthetic results. There were no cases of complete flap loss. Partial flap dehiscence was seen in six patients (14.6%); only two required surgical débridement. None of the patients developed cerebrospinal leaks or meningitis. One patient was left with complete paralysis of the temporal branch of the facial nerve. Three patients (all had received postoperative irradiation) developed permanent trismus. CONCLUSIONS: The temporalis myofascial flap was found to be an excellent reconstructive alternative for a wide variety of skull base defects following tumor ablation. It is a very reliable, versatile flap that is usually available in the operative field with relatively low donor site aesthetic and functional morbidity.
