Direct maxillary irrigation therapy in non-operated chronic sinusitis: a prospective randomised controlled trial.

OBJECTIVE: This study aimed to compare the effectiveness of pharmacological therapy with and without direct maxillary sinus saline irrigation for the management of chronic rhinosinusitis without polyps. METHODS: In this prospective randomised controlled trial, 39 non-operated patients were randomly assigned to be treated with direct maxillary sinus saline irrigation in conjunction with systemic antibiotics and topical sprays (n = 24) or with pharmacological therapy alone (n = 15). Endoscopy, Sino-Nasal Outcome Test and Lund-MacKay computed tomography scores were obtained before, six weeks after and one to two years after treatment. RESULTS: Post-treatment Lund-Mackay computed tomography scores were significantly improved in both cohorts, with no inter-cohort difference identified. Post-treatment nasal endoscopy scores were significantly improved in the study group but were similar to those measured in the control group. The Sino-Nasal Outcome Test-20 results showed improvement in both cohorts, with no difference between treatment arms. CONCLUSION: Maxillary sinus puncture and irrigation with saline, combined with pharmacological treatment improves endoscopic findings in patients with chronic rhinosinusitis without polyps, but has no beneficial effect on symptoms and imaging findings over conservative treatment alone.

Intercostal chest drain fixation strength: comparison of techniques and sutures.

OBJECTIVE: The accidental removal of an intercostal chest drain (ICD) is common and may result in serious complications. A number of fixation techniques and suture material are in use, and the selection is often based on personal preferences and equipment availability. This study is designed to determine which of the common techniques provides the strongest ICD fixation. METHODS: This study compared the mechanical strength of eight different ICD fixation techniques (purse string, 'Roman sandal', 'Jo'burg' (JO) technique, a suture through the tube, one and two passes through a locking plastic tie, tape fixation and a commercial disposable drainage tube holder) and two silk suture sizes using porcine cadavers and a digital push-pull dynamometer to simulate accidental removal of an ICD. A total of 14 different experimental set-ups produced 280 measurements. RESULTS: Significant differences in ICD fixation strength were observed. A modified JO technique using a size 1 silk suture was nearly three times stronger than a purse-string fixation using a size 0 silk and 10 times stronger from a commercial, adhesive-based device (180, 70 and 22, respectively). CONCLUSION: In situations where the mechanical strength of ICD fixation is important, using a size 1 silk and a modified JO technique may provide the strongest fixation.
