ObjectiveChoanal atresia is a rare congenital disorder due to failed recanalization of the nasal fossae during fetal development. This article focuses on our experience in dealing with choanal atresia and its management. Here we discuss the varied clinical symptoms that the patients presented with, the clinical tests and investigations that were specific in diagnosing this condition and surgical management of these cases with endoscopic transnasal choanaplasty with stenting and follow up topical Mitomycin C application.Material and methodsThis is a retrospective study based on computerized medical record review of the patients born in Department of ENT of Sur Hospital between 2002 and 2017. The patients were assessed with detailed history, presentation of clinical symptoms and all underwent nasal endoscopy and CT scans for assessing the atretic type. These patients underwent transnasal endoscopic choanaplasty under general anesthesia using microdebrider and stented using endotracheal tube. The patients were regularly followed up for review with nasal endoscopy after discharge between 4th and 7th postoperative period. The parents were educated on nursing care and the stent was removed in 4 weeks, all patients had Mitomycin C applied to the neochoana and were on regular follow up for a year with no recurrence.ResultsFifteen patient records were analyzed, 10 females and 5 males, ages varying from newborns up to 14 years old. Unilateral to bilateral choanal atresia was 4:1 ratio and female‐male showed 2:1 ratio. Right malformation was predominant in both sexes in unilateral atresia. Mixed imperforation (bone‐membranous) was the most frequently observed type, followed by bone malformation. The commonest symptom during diagnosis was rhinorrhea and the least one was respiratory failure. Majority of cases were diagnosed by CT scans of sinuses. Around 10% patients presented with cardiac problems. None had restenosis in one year follow up.ConclusionsNeonates with acute respiratory insufficiency due to choanal atresia can be diagnosed with simple bedside tests like cold spatula test, less invasive tests like failure to pass intranasal catheter, CT scan. Surgical correction with endoscopic intranasal choanaplasty is the way to address this problem and could avoid radical palatal approach, less morbidity and high success rate.

ObjectiveTo find out the type of bacteria colonising the tracheostomy tube and to determine the antibiotic sensitivity pattern and resistance in patients who have had tracheostomy in intensive care unit (ICU) set up and to initiate proper empirical treatment in such patients.MethodsThe study was a retrospective review of patients who underwent tracheostomy at Ministry of Health, Sur Hospital, Oman January 2005 and December 2015. The Hospital has 4 bedded pediatric intensive care unit (PICU) and 10 bedded adult ICU which is headed by consultant anaesthetists, consultant physicians, ICU trained nurses and respiratory therapists. All patients who required mechanical ventilation and were therefore subject to an orotracheal intubation and those who underwent a conventional tracheostomy were considered for inclusion. Patients who had been intubated in other hospitals or ICUs, other airways infection issues were excluded from this study. Data's were collected from computer based hospital management system, operation theatre and registers in Medical records department and entered in a preformed questionnaire before thorough analysis. The specimens for swab was obtained from the cut tracheostomy tube tips and the samples were sent to microbiology laboratory for isolation of the organism and obtain an antibiogram to know the susceptibility and resistance to antibiotics. Data were analyzed by Statistical Package for Social Sciences (SPSS, version 16, Chicago, Inc) and the values are reported as number (%). The commonest isolated organism was Pseudomonas followed by Acinetobacter.ResultsDuring the ten year retrospective study, there were 108 patients included in our study with 56 males and 51 females. Fourteen different microorganisms were isolated during our study which included Pseudomonas aeruginosa (n = 39), Acinetobacter baumanii (n = 28), Klebsiella (n = 10) and coagulase negative staphylococcus (n = 6). The most commonest organisms in both genders was Pseudomonas aeruginosa closely followed by Acinetobacter baumanii. In children under age of 12, it was Pseudomonas aeruginosa and in adults the impending organism was Acinetobacter baumanii. In terms of antiobiograms, 89% of Acinetobacter, 38% of Staphylococcus aureus, 37% of Klebsiella and 54% of Proteus mirabilis were resistant to ciprofloxacin. These organisms were resistant to ceftazidime in 97%, 83%, 89% and 57% of the cases, respectively and resistant to imipenem in 7.4%, 18.2%, 1.8% and 8.1%.ConclusionsIn summary, this study presents the most common microorganisms colonized from tracheostomy of hospitalized patients and their pattern of antibiotic resistance. As our study showed, Pseudomonas is the most common microorganism isolated from tracheostomy tube. Ciprofloxacin was also the most prevalent antibiotic revealing resistant pattern. Moreover, most of the microorganisms were sensitive to imipenem and pipracillin‐tazobactam.
