Endoscopic Management of Chronic Frontal Sinusitis: Prospective Quality of Life Analysis.

BACKGROUND: Previous studies of endoscopic frontal sinus surgery have been primarily retrospective and focused on symptom relief only. OBJECTIVES: To prospectively assess the impact of endoscopic frontal sinus surgery on frontal sinus ostium patency and disease-specific quality of life as measured by the Rhinosinusitis Disability Index (RSDI). STUDY DESIGN: A 60-patient cohort with chronic frontal sinusitis (100 diseased frontal sinuses) was prospectively evaluated using the RSDI, computed tomography (CT) imaging, and endoscopic examination. Image-guided endoscopic frontal sinusotomy (Draf 2a) was performed in each case. Patients were assessed with RSDI and endoscopic assessment at least 6 months postoperatively. RESULTS: At a mean follow-up of 10 months, endoscopic assessment revealed patent frontal recesses in 90 of 100 frontal sinuses (90%), with significant improvement in the total RSDI score (41.98 ± 26.48 preoperatively to 17.15 ± 15.66 postoperatively) as well as each of its physical, emotional, and functional subscales from 16.3 ± 9.03, 12.23 ± 10.55, 13.45 ± 9.59 preoperatively to 5.95 ± 5.71, 5.55 ± 5.66, 5.65 ± 5.72 postoperatively, respectively. Similar improvement was seen in patients with asthma, polyps, and those undergoing revision sinus surgeries. CONCLUSIONS: With frontal recess mucosal preservation and meticulous postoperative endoscopic surveillance, endoscopic frontal sinusotomy results in high rates of frontal sinus ostium patency with significant improvement in quality of life.

Telescopic-assisted radiofrequency adenoidectomy: a prospective randomized controlled trial.

OBJECTIVES/HYPOTHESIS: The objective was to conduct a prospective randomized controlled trial describing and investigating the efficacy and safety of transoral telescopic-assisted radiofrequency adenoidectomy in young children. STUDY DESIGN: Prospective randomized controlled trial. METHODS: One hundred twenty patients who were 36 months of age or less and planned to undergo adenoidectomy or adenoidectomy with insertion of tympanostomy tubes were included in the study. Children were prospectively and randomly assigned into two equal treatment groups: the telescopic-assisted adenoidectomy using radiofrequency curette and the conventional adenoid-curette adenoidectomy. The main parameters included visual analogue scale score for nasal breathing, amount of blood loss, operating time, completeness of adenoid resection, smoothness of postoperative recovery, and complications. RESULTS: Both groups had a significant improvement in the visual analogue scale score after surgery with no evidence for a significant difference between the conventional adenoid-curette and radiofrequency groups. The amount of blood lost during radiofrequency adenoidectomy was minimal, with a mean difference of 31 mL and a median difference of 26 mL. There was a tendency for shorter operative time in the radiofrequency group, but this did not reach a statistical significance. No evidence for a significant difference was noticed in the smoothness of postoperative recovery or complication rate. CONCLUSION: Telescopic-assisted radiofrequency-curette adenoidectomy allows removal of huge adenoids completely in a precise, easy, and cost-effective procedure, with minimal blood loss and short operating time. The use of transoral telescopes provides a clear visualization that helps complete removal of the adenoids, reduction of unnecessary trauma, and effective control of bleeding.

Epidemiology, causative agents, and risk factors affecting human otomycosis infections.

BACKGROUND/AIM: Otomycosis, or fungal otitis externa, has typically been described as fungal infection of the external auditory canal, with infrequent complications involving the middle ear. This study assessed a mycological analysis of fungal debris from externalauditory canals of patients at Tanta University Hospital, Gharbia Governorate, Egypt. MATERIALS AND METHODS: The samples were collected over a year from the 110 patients that were clinically diagnosed to have otomycosis. The samples were then inoculated and culture plates were examined for the presence of fungal growth. RESULTS: The results showed that Aspergillus niger was the most common fungus causing otomycosis. It was more common among males aged 21-40 years. The incidence was higher in the summer and spring seasons. Manual workers and students had the highest frequency based on occupational incidence. The most common presenting complaint was itching. Trauma to the external auditory canal was the most common predisposing factor. CONCLUSION: The epidemiological profile of otomycosis infection varied according to different factors in the study population.

Mitomycin C-enhanced revision endoscopic dacryocystorhinostomy: a prospective randomized controlled trial.

OBJECTIVES: (1) To conduct an adequately powered randomized controlled trial investigating the safety and efficacy of mitomycin C-enhanced revision endoscopic dacryocystorhinostomy (DCR) and (2) to analyze causes of failure after primary endoscopic DCR. STUDY DESIGN: A randomized controlled study. SETTING: General hospital. SUBJECTS AND METHODS: Seventy-six revision endoscopic DCRs were randomized into 2 groups: endoscopic DCR with mitomycin (group I), where 0.5 mg/mL mitomycin C was applied for 10 minutes, and endoscopic DCR without mitomycin (group II). Follow-up settings were done to document the patient's subjective improvement, to judge ostium patency on irrigation, and to record any complications. RESULTS: Causes of failure in the original 92 patients included canalicular obstruction (14%), small misplaced bony window (43%), very small nasolacrimal stoma due to development of synechia (23%), and complete closure of nasolacrimal stoma with tough fibrous tissue (63%). There was no significant difference between the 2 groups in subjective and objective success rates and adverse events. Group I demonstrated a significantly longer operative time and a significantly lower number of debridement sessions (mean of 1.2 vs 1.9). CONCLUSIONS: Recurrent nasolacrimal duct obstruction after primary endoscopic DCR is mainly due to reclosure of the nasolacrimal stoma with synechia and fashioning of the small misplaced bony window. Mitomycin C does not increase the success rate of revision endoscopic DCR. It is a safe procedure and may be of value only in patients inaccessible to strict follow-up because it induces a better healing profile in terms of mucosal recovery, wound healing, and less need for debridement sessions.
