ABSTRACT
Background: There are different surgical techniques to remove Oral mucoceles, including conventional surgery with scalpel, removal of the lesion with CO2 laser, and micro marsupialization. The present systematic review was conducted with the aim of comparing the recurrence rate of different surgical techniques for treatment of the oral mucoceles. Material and Methods: An electronic search for randomized controlled trials published in English until September 2022 related to different surgical methods for the treatment of oral mucocele was performed in Medline/PubMed, Web of Science, Scopus, Embase and Cochrane databases. A random-effects meta-analysis was conducted to compare the recurrence rate of different techniques. Results: Among 1204 papers initially identified, after the removal of duplicate articles and screening of the titles and abstracts, fourteen full-text articles were reviewed. Seven articles comparing the recurrence rate of oral mucocele in different surgical techniques were found. Seven studies were included in qualitative studies, and five articles were included in the meta-analysis. The risk of mucocele recurrence in the micro-marsupialization technique was 1.30 times that of the surgical excision with scalpel technique, which was not statistically significant. The risk of mucocele recurrence in the CO2 Laser Vaporization technique was 0.60 times that of the Surgical Excision with Scalpel technique, which was not statistically significant. Conclusions: The results of this systematic review showed that there is no significant difference between the recurrence rate of surgical excision, CO2 laser and marsupialization techniques for the treatment of oral mucoceles. Although more randomized clinical trials are needed for definitive results. (AU)

Statement of the Problem: The surgical repair of nasal septal perforation (NSP) has always been a challenging procedure and no consensus has been made about a definitive protocol. Purpose: In the current study, we investigated the use of cryopreserved amniotic membrane with mucosal rotational flap for the surgical repair of NSPs. Materials and Method: In this prospective clinical study, 12 patients with symptomatic NSP underwent primary surgical repair, between December 2018 and October 2019. The surgical procedure comprised of a rotational flap on one side of the defect and cryopreserved amniotic membrane as an interpositional graft in the mucoperichondrial pocket on the other side. The patency of defect was checked at a follow-up appointment at least 3 months after surgery. Results: Successful repair was perceived in 10 of 12 (83%) of patients. Reperforation occurred in two patients but the size of the defect was smaller than the original one. All of the patients reported elimination of all symptoms associated with NSP. Conclusion: The use of cryopreserved amniotic membrane as an interpositional graft accompanied by a mucosal rotational flap seems to be efficient in alleviating the symptoms of NSP and closure of the defect.
ABSTRACT
PURPOSE: To the assess sensitivity and specificity of urinary levels of hyaluronic acid (HA) and hyaluronidase (HAase) as an individual or a combined test to diagnose bladder transitional cell carcinoma (TCC). MATERIALS AND METHODS: One hundred and ninety-four urine specimens were collected from individuals between July 2007 and March 2008. The urinary level of hyaluronic acid (HA) was measured by Enzyme-linked immunosorbent assay. Thereafter, the urinary levels of HA and HAase were normalized to urinary creatinine level and expressed as ng/mg and µ/mg. RESULTS: Eighty percent of patients with bladder cancer had urinary HA level < 500 ng/mg, and 90% of controls showed HA level < 500 ng/mg (P < .001). The mean urinary levels of HA in controls did not vary significantly (P < .05), whereas they significantly increased (2.5 to 6.5 folds) in all grades of TCC. More than 80% of patients with grades 2 and 3 TCC had urinary HAase level < 10 µ/mg and over 80% of controls showed HAase level < 10 µ/mg (P < .05). Hyaluronidase levels increased in patients with grades 2 and 3 bladder TCC. CONCLUSION: Measurement of urinary levels of HA and HAase (with 89% sensitivity and 83% specificity) appears to be a highly accurate and non-invasive method for detecting bladder TCC and evaluating its grade.
