Impact of Intranasal Splint Removal Time on Postoperative Complications after Septoplasty.

BACKGROUND: Various types of nasal tampons are used for packing after septoplasty. Intranasal splints are widely used as they are more advantageous than other materials regarding the lower complication rates of synechia, and lesser pain during removal. However, there is no consensus on the timing of intranasal splint removal after septoplasty operations. AIM: In this study, we aimed to investigate the effects of removal time of intranasal splints on postoperative complications after septoplasty. METHODS: One hundred patients who had septoplasty were randomly divided into two groups according to splint removal time. In group I, the splints were removed on the third postoperative day and in group II, splints were removed on the seventh postoperative day. Pain during splint removal was evaluated by visual analog scale (VAS). Complications of hemorrhage, septal hematoma, crusting, mucosal injury, and infection were recorded during splint removal and compared. In the first postoperative month, hemorrhage, crusting, mucosal injury, infection, synechia, and in the second postoperative month, synechia and perforation rates were compared between two groups. RESULTS: Mucosal crusting was significantly higher in group II during splint removal. There was no statistically significant difference between the two groups regarding the complication rates and pain scores. Our findings showed no significant difference in pain scores during splint removal and postoperative complications between the two groups except for mucosal crusting. CONCLUSION: Based on our findings, although there is no consensus on the optimal time for splint removal, earlier removal of splints can be considered a favorable option after septoplasty operations.

Impact of titanium-prepared platelet-rich fibrin in type 1 fascia graft tympanoplasty on graft survival and hearing outcomes.

Background: Type 1 fascia graft tympanoplasty (T1FGT) is the mainstay surgical approach for the treatment of tympanic membrane perforations. The most widely used graft material is temporal muscle fascia, and graft take rates are reported differently. The methods to enhance graft take are still being investigated. Aim: The aim of our study was to investigate the effect of titanium-prepared platelet-rich fibrin (T-PRF) on graft take and hearing outcomes in T1FGT. Materials and Methods: Fifty-seven ears eligible for T1FGT were involved in the study and prospectively evaluated. T-PRF was applied with T1FGT in 27 ears. Thirty ears in the other group underwent only T1FGT. The patients underwent an otomicroscopic and audiometric examination in preoperative and postoperative 2nd week, 1st month, and 6th month. Both groups were evaluated in terms of hearing levels, infection, and graft take rates. Results: Two patients in the T1FGT + T-PRF group and seven patients in the T1FGT group had postoperative perforation (graft take rate: 92.6% versus 76.7%). The graft take rate was found to be increased in the T-PRF group although the difference was not statistically significant. In the T1FGT group, the percentage of infection was higher than in the T1FGT + T-PRF group. When the preoperative and postoperative 6th-month audiometry was compared, a statistically significant hearing gain was obtained for both groups. Conclusion: In the treatment of tympanic membrane perforations, T-PRF applied over the fascia graft was shown to increase graft take rates and decrease the probability of infection. Further studies with larger samples are needed to demonstrate the effects of PRF.

A 15-year retrospective study of 160 cases of benign lip lesions.

OBJECTIVE: This study aimed to describe the results of a retrospective analysis of a specific cohort of patients with benign lip lesions encountered in the last 15 years in the School of Medicine at Karadeniz Technical University. METHOD: A total of 312 patients were managed for lip lesions during the period 2000-2014. Data from 160 samples of benign lip biopsies were retrieved from the pathology laboratory records. RESULTS: The study group included 20 different histopathological types of lesions, with mucocele being the most frequent lesion (43.13 per cent). The other frequent lesions were chronic inflammatory infiltrate (11.25 per cent), intradermal naevus (5.63 per cent), pyogenic granuloma (5.63 per cent), fibroma (5 per cent) and papilloma (5 per cent). Mucocele was significantly more common in younger patients (p < 0.001). CONCLUSION: Knowledge of the epidemiology and distribution of oral mucosal lesions is essential to promote early diagnosis and treatment. Further epidemiological studies exploring the causal relationships and risk factors for lip lesions are necessary for a better understanding of lip diseases.

Universal newborn hearing screening; automated transient evoked otoacoustic emissions.

OBJECTIVE: The purpose of this study is to describe the results of universal newborn hearing screening (UNHS) in 2229 newborns and to assess the effectiveness of a two-stage automated transient evoked otoacoustic emission (a-TEOAE) test protocol. MATERIALS AND METHODS: Between May 2007 and January 2008, a universal newborn hearing screening program, instituting two-stage a-TEOAE, was evaluated. The hearing status of the newborns who failed the two-stage screening tests were evaluated with the auditory brainstem response (ABR) test during the diagnostic stage. The risk factors for hearing loss determined by the Joint Committee on Infant Hearing Loss (JCIH) and prematurity, consanguineous marriage, and birth type as presumptive risk factors were recorded. RESULTS: During the study period, 2229 newborns were screened. Sensorineural hearing loss (SNHL) was identified in 8 newborns. Fourteen newborns were lost to follow-up. One hundred thirty six newborns were high-risk neonatal intensive care unit (NICU) patients. The prevalence of SNHL was 2.9% (4/136) in NICU newborns, and 0.19% (4/2079) in the well-baby nursery. SNHL prevalence in the study group overall was found to be 0.36% (8/2215). Craniofacial anomalies and family history of hearing loss were found to be significantly related to SNHL in newborns. Prematurity and consanguinity that are not listed among JCIH risk factors were also found to be statistically significantly related with SNHL. CONCLUSIONS: This is the first report of a universal hearing screening program in the Eastern Black Sea region of Turkey. Two-stage a-TEOAE is an efficient and feasible hospital-based screening protocol in newborns.

Fat-plug and paper-patch myringoplasty in rats.

OBJECTIVE: The purpose of this study is to investigate the recovery rate in paper-patch and fat-plug myringoplasty in rats. METHOD: Small and large perforations were inflicted on the tympanic membranes of 60 rats. Fat-plug and paper-patch myringoplasties were performed to different groups and another group was left for spontaneous healing. RESULTS: We found that for small perforations, the recovery rate was 94.7% in fat-plug myringoplasty, 94.4% in paper-patch myringoplasty, and 66.6% in control group. The recovery rates in large perforations were 52.9%, 56.2%, and 26.6%, respectively. On the other hand, in larger perforations, paper-patch or fat-plug myringoplasty have not been found effective. CONCLUSION: We believe that due to significant operational advantages, fat-plug or paper-patch myringoplasty can be suggested for the reconstruction of small and dry perforations of the tympanic membrane.

Serum adenosine deaminase and total superoxide dismutase activities before and after surgical removal of cancerous laryngeal tissue.

In this study, pre- and post-operative serum activities of adenosine deaminase (ADA) and total superoxide dismutase (SOD) enzymes were measured in patients with squamous cell laryngeal cancer. Activities of both enzymes were found to be higher in cancerous patients compared to the controls. No significant differences were found however between pre- and post-operative values for both enzymes in the patient group. It has been suggested that ADA and SOD enzymes leak from the cancerous laryngeal tissues into the blood stream. The absence of differences between pre- and post-operative serum enzyme activities has two possible explanations: Firstly, removal of previously released enzymes from the blood stream takes a much longer period than one month; and secondly, cancerous laryngeal tissue is not the only source of the enzymes mentioned even after removal of cancerous tissue by surgical operation, other sources such as adjacent tissues and/or metastatic tissues etc, still release these enzymes into the blood stream.

Concentrations of some major and minor elements in larynx tissues with and without cancer.

In this study, concentrations of some major and minor elements were determined in the larynx tissues with and without cancer, and results obtained were statistically compared. No meaningful differences were found between sodium, potassium, calcium and copper concentrations in cancer tissues, corresponding cancer-free adjacent tissues and in control larynx tissues. Phosphate concentrations of the cancer tissues were higher compared with cancer-free adjacent tissues and control tissues. Iron, zinc and magnesium concentrations were found increased in both cancer and corresponding cancer-free adjacent tissues relative to control values. Intra- and inter-element correlations established within and between groups indicated that relations between elements were also disordered in the cancer tissues. We suggest that the changed element status of cancerous larynx tissues may arise from increased requirements of cancer tissues for some elements such as iron, zinc, magnesium and phosphate.
