Teratomas are benign tumours containing tissues derived from ectoderm, endoderm and mesoderm Epignathus is a rare congenital teratoma and originates from oropharyngeal region. We present a case of giant epignathus arising from tonsillar region in a neonate. A male neonate that was born with a 38-week cesarean section presented with a pedunculated mass from left tonsilla palatina and protruding outside the mouth. The patient did not have any airway problem. Magnetic resonance imaging and computed tomography scan showed no intracranial extension. The patient was operated on the postpartum 3rd day and the mass was excised successfully. After histopathological examination, mature teratoma was diagnosed. During post-operative 6 months control visit, there was no recurrence. Epignathus is a rare congenital oropharyngeal teratoma, it should be diagnosed in the fetus as early as possible. Teratomas of the tonsilla palatina are extremely rare. In such cases, the mass may cause airway obstruction and feeding difficulties so complete resection is curative in most cases during the early neonatal period.

Objective: Noise-induced hearing loss (NIHL) is one of the most important problems affecting both social and professional life of patients. There is no treatment method considered to be successful on the hearing loss that has become a permanent nature. Aim of this study is to evaluate protective effect of Korean Red Ginseng (KRG) against NIHL in an animal model.

Methods: Twenty-eight rats were separated into four groups [control saline (group I), control KRG (group II), saline + noise (group III), KRG + noise (group IV)]. Rats in the saline and KRG groups were fed via oral gavage with a dose of 200 mg/kg/day throughout for 10 days. Fourteen rats (group III and IV) were exposed to 4 kHz octave band noise at 120 dB SPL for 5 hours. Hearing levels of rats were evaluated by distortion product otoacoustic emissions (DPOAE) and auditory brainstem responses (ABR) at 4, 8, 12, 16 and 32 kHz frequencies prior to and on days 1, 7 and 10 after the noise exposure. Rats were sacrificed on 10th day, after the last audiological test. Cochlea and spiral ganglion tissues were evaluated by light microscopy.

Results: Audiological and histological results demonstrated that after noise the group IV showed better results than group III. In the noise exposed groups, the most prominent damage was seen at the 8 kHz frequency region than other regions. After the noise exposure, DPOAE responses were lost in 1st, 7th and 10th measurements in both group III and IV. Thus, we were not able to perform any statistical analyses for DPOAE results.

Conclusion: Our findings suggest that KRG seems to be an efficient agent against NIHL. There is need for additional research to find out about the mechanisms of KRG's protective effect.

Objective: The aim of our study was to assess the possible short-term effects of topical and oral eugenol on the suppression of experimentally developed myringosclerosis (MS).

Methods: Four groups of seven male Wistar albino rats were used in the study. The tympanic membranes (TMs) of all subjects were myringotomized, and group 1 was given no treatment (as control group), group 2 received saline, group 3 had received topical eugenol and group 4 received oral eugenol.

Results: In macroscopic evaluation the control and saline groups showed much more MS compared to the topical and oral eugenol groups which had statistically significantly less changes (p<0.05). Fibrosis and inflammation regarding the lamina propria (LP) of the eardrums of the topical and oral eugenol groups were significantly less than those of the control and saline groups (p<0.001). In microscopic evaluation, TMs were found to be thicker in the control and saline groups (p<0.001).

Conclusion: Our study showed that the application of topical and oral forms of eugenol reduced fibrosis and prevented the advancement of MS in the LP of the TMs in the short-term. More studies with different extracts are needed to investigate the efficacy of phytotherapeutic agents for preventing MS development following myringotomy.

As the aerospace industry has grown rapidly over the years, aviators and astronauts have been exposed to some abnormal physiological changes arising from the dynamics of the aerospace environment. The vestibular system, encoding linear and angular movements of the head, is one of the main affected systems in which those abnormal changes can occur during flight. Despite the intricate and solid organization, vestibular units are such delicate structures that they can easily be deceived by aerial dynamics and gravity changes. Therefore, it is of vital importance for the continuity of flight safety to be aware of the detrimental alterations and impairments regarding the vestibular system and its reflex pathways. The aim of this paper was to present a review about how a healthy vestibular system is negatively affected within the aerospace environment and how some vestibular disorders become exaggerated or impaired during aviation and space activities.

We report the case of a 54-year-old woman who presented to the ear, nose, and throat (ENT) outpatient clinic with hearing loss, tinnitus, and fullness in her right ear. In the first clinical examination, a pouch hanging in the anterior upper quadrant was detected in the tympanic membrane of the right ear. A tick larva was found in the cyctic lesion located on the tympanic membrane. Our case was unique due to this unexpected diagnosis.

Objective: The primary aim of the study was to perform sequential analyses together with a citation analysis on the characteristics of the studies published in the Turkish Archives of Otorhinolaryngology (TAO) in the periods of 2010-2014 and 2015-2019.

Methods: The studies published in the indicated periods were reviewed for study type, study topic, language and country of origin. Then, the citation analysis of the articles was performed through the Google Scholar and Web of Science (WoS) databases for the indicated periods. The estimated annual impact factors (EIF) of TAO from 2017 to 2020 were calculated by dividing the total number of citations performed in the projected year to the total number of citable articles published in the preceding two years.

Results: The total numbers of articles published from 2010 to 2014 and from 2015 to 2019 were 144 and 214, respectively. In 2010 to 2014, the most frequent study topic was head and neck with case reports ranking highest among study types. In 2015-2019, the most frequent study type had changed to original investigation and topic to general otorhinolaryngology. There was a remarkable increase in the total number of citations in 2015-2019 according to Google Scholar and WoS databases. Also, there was a remarkable increase in the EIF values for 2019 and 2020.

Conclusion: Although the increase in the number of citations and impact factor values cannot be appreciated as a single indicator for the success of a journal, the results of the presented study showed a promising advancement in the scientific quality of the TAO, driven by the inclusion of the journal to national and international indexes and by changing the language of the journal to English, as well as the well-orchestrated editorial efforts.

Objective: To determine flap success rate and complications in patients who underwent microvascular free tissue reconstruction after major head and neck ablative surgery and to report the improvement in the results.

Methods: Medical records of 124 patients who were operated on in 2012 to 2019 were retrospectively reviewed. Indications for different free flap types, success rates and re-exploration rates, donor site morbidities, and reasons for flap loss were analyzed. Patients were divided into two groups to identify the effects of the anticoagulant and the antiaggregant treatments on postoperative results.

Results: There were 127 flaps in 124 patients, including two different free flaps each in three patients that were harvested and used in the same surgical session. Of the total 127 flaps, 82 (64.6%) were radial forearm flaps, 39 (30.7%) were fibula flaps, and 6 (4.7) were rectus abdominis flaps. Four patients were re-explored for flap perfusion problems, and 18 patients were re-explored for hematoma drainage (n=22/124, %17.3). The rate of hematoma and re-exploration was higher in patients who received anticoagulant and antiaggregant treatments synchronously (p=0.02). Three flaps were lost, and the overall success rate was 97.6%. Two patients died from perioperative complications. No major complications were observed at the donor site; minor complications were observed in 30 patients.

Conclusion: The success rate for the 127 flaps in 124 patients were found comparable to those reported in the literature. These results show that successful outcomes can be achieved with experience and a head and neck team dedicated to improving the results in microsurgical reconstruction, and flap failure rarely occurs if perioperative care of the patients is given meticulously.

Object: To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients.

Methods: The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors. A workshop was organized at the very beginning to explain the details of the study to the team. Advisors took the chance to meet their coworkers in their subgroups and determined the main headings and subheadings of the guideline, together with the authors. After key words were determined by the authors, literature search was done in various databases. The authors keep in touch with the advisors and the advisors with the advisory committee and the support group at every stage of the study. National and International published articles as well as the abstracts of unpublished studies, imperatively presented in National Congresses, were included in this guideline. Only Guideline and meta-analyses published in last seven years (2013-2017) and randomized controlled studies published in last two years (2015-2017) were included. After all work was completed by the subgroups, support team brought all work together and edited the article.

Results: A detailed guideline about all aspects of allergic rhinitis was created.

Conclusion: The authors believe that this guideline will enable a compact and up-to-date information on allergic rhinitis to healthcare professionals. This guideline is the first in the field of Otolaryngology in Turkey. It should be updated at regular intervals.

Pseudoaneurysm is a rare vascular complication of trauma, causing an incomplete tear of the vessel wall. We present a clinical case report arising from the distal branch of facial artery in an infant. Facial artery pseudoaneurysm is a rare complication of facial trauma and can easily be misdiagnosed especially in the paediatric age group. Prompt investigation and diagnosis with timely and apt intervention is the key to the successful management of facial artery pseudoaneurysm.

Objective: Septal mucosal-perichondrial flaps can be lacerated during the elevation of the flaps. Appropriate repair of the lacerations is essential to prevent the development of septal perforation during the healing process. We aimed to determine the superior suture type and suture distance to use in repairing the lacerations of nasal septal mucosal-perichondrial flaps.

Methods: The study used 128 nasal septal mucosal-perichondrial flaps prepared from sheep heads. Experimentally induced lacerations on the mucosal-perichondrial flaps were sutured with two interrupted sutures using one of four suture materials (4-0/5-0 Polyglactin 910, 4-0/5-0 Polydioxanone) and leaving either 5 mm or 10 mm distance between the sutures. Maximum tissue holding strength (HS_max) was measured for each suture material and suture distance used.

Results: Mean HS_max values were higher for Polyglactin 910 sutures (p<0.001) and 10 mm suture distance (p=0.008) when the groups were compared in terms of suture material and suture distance, respectively. There was no statistically significant difference between the mean HS_max values of sutures with 4-0 and 5-0 diameters (p=0.057).

Conclusion: Polyglactin 910 suture material with 10 mm space between two adjacent sutures may be more durable than the other suture materials when repairing nasal septal mucosal lacerations.
