Background:  Salivary gland neoplasms represent rare cancers. Bilateral tumors of the parotid gland is very rare.

Case Presentation: An old man with bilateral parotid mass starting from 3 months ago, he had a history of SCC of scalp.

Background:  Cholesterol granuloma is a histological term used for the description of a tissue response to the presence of an irritant foreign body, i.e. a cholesterol crystal.  we report a cholesterol granuloma occupying the EAC of a17 year old teenage girl.

Case Presentation: A 17 years old teenage girl presented with active otorrhea in the right ear. On physical examination the pink mass was visible in the right ear canal and the radiologist reported an expansile well-marginated lesion.

Background: Laryngomalacia is one of the most common causes of neonatal dyspnea and inspiratory stridor. In 20% of the cases laryngomalacia in newborns may lead to respiratory failure, feeding difficulties and failure to thrive. The aim of this study was to assess the changes in the quality of life of the patients with laryngomalacia in the first year following ultra-dream pulse laser supraglottoplasty.

Case presentation:  the assessment relevant parameters of 6 newborn patients with laryngomalacia (4:2 male:female, average age at the time of operation 12,5 days) who underwent ultra-pulse laser supraglottoplasty.

Conclusion: Ultra-dream pulse laser supraglottoplasty for laryngomalacia is a safe and effective surgical modality, even if it is performed in the neonatal age.

The treatment of upper airway stenosis is considered to be one of the most difficult fields in laryngology. In the 100-year-old history of airway stenosis surgery several important works of Hungarian authors (Rethi, Lichtenberger, Pytel) are found.

At the Department of Oto-Rhino- Laryngology and Head- Neck Surgery, University of Szeged our workgroup has been working on the treatment of upper airway stenosis for more than 30 years.

Hereby we introduce our surgical concept for bilateral vocal fold paralysis, the minimally invasive endoscopic arytenoid abduction lateropexy (EAAL), which provides an immediate adequate airway with acceptable voice quality, and good swallow function.

A new Endolaryngeal Thread Guide instrument (ETGI) is also presented here, which is essential for a safe, accurate, and fast suture loop creation around the arytenoid cartilage for this surgical procedure.

Background: Today, hearing disorders are one of the most common problems in an industrial society. High-intensity sounds can induce apoptosis and metabolic changes in the auditory neural pathway and auditory cortex.

Aim: In this study, we investigated the effect of chronic noise exposure on Bax, Bcl-2 and Caspase-3 genes expression in the auditory cortex of rats.

Methods: Chronic exposure to 110 dB white noise was applied in male rats for 6 hours for 5 consecutive days. Superoxide dismutase (SOD) activity was measured in the serum of rats prior to and following noise exposure. Bax, Bcl-2 and Caspase-3 genes expression in the auditory cortex was determined by Real time PCR assay. 

Results: Our results showed that the serum SOD level was significantly decreased in rats exposed to noise. In addition, the gene expression of Caspase-3 and Bax/Bcl-2 ratio was markedly increased in the auditory cortex of rats were subjected to chronic noise exposure compared to control rats.

Background and Aim:The internal nasal valve is the narrowest area of nasal airway bounded by the nasal septum, the caudal edge of upper lateral cartilage and the anterior head of the inferior turbinate. Knowledge about this area is of utmost importance for every nasal surgeon.

This study was done to evaluate the internal nasal valve angle and cross sectional area in Iranians.

methods:

This is a retrospective study done using data from cross sectional imagings available from patients who underwent image guided endoscopic skull base surgery between 2013 and 2017. An image navigation software [Osiri- x: 8.5.2] was used for display of the multidimensional images.

Results:Collectively 43 cases (i.e. 86 nasal passages) including 24 males and 19 females in the age range 21 – 74 years (48 ± 13.6) participated in the study.

The internal nasal valve angle of naval cavities of the 86 subjects was averaged and the mean value of 17.70º (±3.72) was obtained. Mean value for cross sectional area was of 1.40 cm²(±0.38).

There was not a statistically significant difference between males and females in terms of the nasal valve angle and nasal valve cross sectional area.

Conclusion: We found some differences between the nasal valve angle and cross sectional area between Iranians and values of Asians / Japanese and Caucasians reported in previous studies. Despite these findings, reaching a conclusion needs further large sample studies in different ethnic groups paying special attention to similar case selection and study design.

Background: nasal tip ptosis is believed to be one of the most common nasal malformations with a relatively high prevalence in patients who underwent rhinoplasity operation. A variety of techniques has been defined for the surgical modification of tip ptosis. The TIG technique seems to be a multipurpose surgical approach for the modification of nose in the lower third region. TIG could be appropriate in the primary and most modified cases and to show better results, it has been integrated with other surgical systems.

Aim: The aim of this study is to investigate TIG technique in patients with nasal tip ptosis after Rhinoplasty, referring to Loghman-E- Hakim hospital, Tehran, Iran.

Methods: In following descriptive cross-sectional study, surgical operation was carried out in thirty-three patients suffering from nasal tip ptosis between 2012 and 2013 using the described technique. The data were gathered in a questionnaire designed for this purpose. At the end, the degree of nasal ptosis was determined in these patients.

Results: In this study, nasal shape was desirable in 75.7% of patients and there was no case of nasal ptosis. 82.8% of the patients were satisfied with the results. 81.1% of patients have not any complications. Other factors did not associate with nasal ptosis (P> 0.05).

Conclusion: based on the results of this study and their comparison with other studies conducted in this field, TIG method after rhinoplasty can reduce nasal ptosis. Thus, it can be deduced they will be proper in the both primary and most revision cases.

Background: It is a well-known fact that deviation of bony or cartilaginous septum can induce airway obstruction. Therefore, fixing the deviated part in a refined and straight line is one of the substantial challenges in otolaryngology. There are huge varieties of methods to eliminate this deviation.

Aim: In this study, we desire to assess the efficiency of polydioxanone plate (PDS), fixed to the cartilage of nasal septum, to determine the mechanical safety over septoplasty, as the components of cartilage had been healed.

Methods: In the following study, 48 patients with septal deviation, referring to an academic hospital in Iran for one year, were investigated. They underwent external and endoscopic septoplasty combined with the polydioxanone plate. The data was gathered in a questionnaire including the deviation of nasal septum, infection, septal hematoma, saddle nose, columella retraction and polly beak deformity.

Results: Due to the septal injury resulted from trauma, a total of 27.1% patients was transferred to our hospital. Our results showed the cause and type of septal deviation had no effect on surgical results (p = 0.3), and acute complications were observed in only two patients (4.2%). After 3-6 months of follow up, 5 patients (10.42%) had long-term complications, while satisfactory results were obtained in 39 subjects (83%).
