RESUMO
BACKGROUND: Nostril sill asymmetry is one of the most challenging problems in rhinoplasty. Some studies have been performed regarding nostril shape; however, no studies have been conducted on nostril shape in the Persian population. Additionally, the shape of the nostril in frontal view has rarely been evaluated. This study has two aims. The first is to evaluate nostril shape in Persian patients who were candidates for primary rhinoplasty in basal and frontal views. The second is to assess augmentation silloplasty in patients with different sill heights to resolve nostril asymmetry. METHODS: This research was performed in two phases. The first phase was a cross-sectional study carried out on the deidentified photographs of 122 patients nominated for rhinoplasty surgery at the facial plastic clinic of a tertiary university hospital. The second phase of the research was an interventional study without a control group consisting of 22 patients. The subjects were categorized as Phase 1. Next, an attempt was made to symmetrize nostril heights by sill augmentation surgery. One year after silloplasty surgical outcome was evaluated by measuring the differences in sill heights. RESULTS: In the first phase, classification was performed of the nostril shapes of the patients using two views: frontal and basal. Morphologic study has revealed that there are two types of nostrils in the frontal view and three types in the basal view. In the second phase of this research, augmentation silloplasty was employed for the correction of asymmetric sill heights between the right and left sides. The results show that the height differences in the two sills decreased by 44.26% one year after surgery compared to before surgery (CI: 95%, range - 20.59 to - 67.93), which is statistically significant (p = 0.0002) CONCLUSIONS: Classification of nasal base and nostrils relying on visual inspection is still an important tool for clinical evaluation and communication among physicians. This classification is also crucial in selecting the proper method for correcting nasal base asymmetry. Augmentation silloplasty can help surgeons correct nostril asymmetry due to sill height discrepancy.

PURPOSE: To investigate associations between polysomnographic findings and the severity of upper airway obstructions during Muller's Maneuver (MM) and Drug-Induced Sleep Endoscopy (DISE) in patients with obstructive sleep apnea syndrome (OSAS). METHODS: This was a prospective cohort study. Adult patients newly diagnosed with OSAS in a tertiary sleep center were included consecutively and evaluated by polysomnography and MM. They then underwent DISE in an operating room. The associations between polysomnographic findings and the severity of upper airway obstructions during MM and DISE were assessed. Also, the degree and pattern of obstructions were compared using a modified VOTE questionnaire. RESULTS: 145 patients (mean age 41.5 ± 10.1 years) were enrolled. There were no associations between Respiratory Disturbance Index (RDI), mean and lowest O2 saturation, and body mass index on the one hand, and obstruction degree in MM and DISE (p > 0.05). However, a significant positive correlation was observed between RDI and total VOTE scores in DISE and MM (r = 0.179, p = 0.031 and r = 0.221, p = 0.008 respectively). There were no differences between MM and DISE in diagnosing the degree of obstruction in the velum area (p = 0.687) and the epiglottis (p = 0.50). However, a significant difference was observed between the two techniques in the oropharynx lateral wall (p < 0.001) and tongue base (p = 0.017). CONCLUSION: Although there was no association between polysomnographic findings and the severity of obstruction in MM and DISE for the separate levels of the upper airway, obstruction severity may be assessed more accurately by total VOTE score, which is representative of RDI severity.
RESUMO
Garcin syndrome is characterized by progressive unilateral multiple cranial nerve palsy without the presence of intracranial hypertension. In this case, we present a patient who experienced lower cranial nerve (CN 9-12) involvement attributed to post-mucormycosis osteomyelitis of the skull base. The osteomyelitis resulting from mucormycosis led to the development of Garcin syndrome, which manifested as progressive paralysis of the cranial nerves. It is important to recognize this rare complication and consider it in the differential diagnosis when evaluating patients with lower cranial nerve palsy following mucormycosis-related skull base osteomyelitis.
RESUMO
Introduction: The best strategy to treat otitis media with effusion in cleft lip/palate patients is still under debate. This research aimed to evaluate the otologic outcomes in children at least five years post-repair. Materials and Methods: A retrospective study was conducted on 40 children who underwent palatoplasty between January 1, 2012, and January 1, 2014, at Children's Medical Center (Tehran, Iran). Patients had intervelar veloplasty under magnification (Sommerlad's Technique). Based on patients' charts, their age, gender, cleft type, date of palatoplasty, as well as the date and the frequency of ventilation tube (VT) insertion, were recorded. Furthermore, otomicroscopy, middle ear status, and tympanometry were assessed five years postoperatively. Results: There was no significant difference in middle ear status between children with complete and incomplete cleft palates. The mean age at the time of study and the mean follow-up duration were significantly higher in the normal middle ear group, compared to the abnormal middle ear group (7.7±1.6 vs. 6.8±0.9, P=0.03 and 6±1.15 vs. 5.42±0.9, P=0.04, respectively). Middle ear status was not significantly different between early or late palatoplasty patients. In addition, the frequency and timing of VT insertion were not significantly different between the two groups. Conclusions: Middle ear status improved as patients grew older; however, the age of palatoplasty and the frequency of VT insertion were not significant prognostic factors in patients who underwent intervelar veloplasty under magnification.
RESUMO
To assess the efficacy of intralesional injection of bleomycin for treatment of pediatric lymphangiomas in head and neck region in Iranian population. This prospective study was conducted from February 2017 to March 2019. All consecutive patients presented to pediatric otolaryngology clinic in Children Medical Center Hospital in Tehran with macrocystic lymphangiomas of head neck were enrolled in this study. Informed consent was taken from parents. Bleomycin was diluted to a concentration of 1 mg/ml by normal saline and a dose of 0.5 mg/kg was injected into the lymphangioma. Ultrasonography was performed before and after each injection at 1, 3, 6 and 12 months. Age, gender, number of injections, size of lymphangioma and complications including fever, discoloration and respiratory problems were recorded. A total of 20 patients were assessed. Mean age at first injection was 31.9 months. Average reduction in size was 84%. Complete disappearance of mass was observed in 65% (13/20) of patients. Twenty-five percent (5/20) of patients had more than 50% reduction in size. Ten percent (2/20) had unsatisfactory results. Three patients developed transient erythema or swelling of injection site, but none of the patients had any respiratory problem. Intralesional injection of bleomycin is an effective modality to use as a first-line treatment of macrocystic head and neck lymphangiomas in Iranian pediatric population.
RESUMO
INTRODUCTION: The present study aimed to compare the effects of paracetamol and ibuprofen on pain, bleeding, nausea, and vomiting following adenotonsillectomy in children. MATERIALS AND METHODS: This was a prospective, double-blinded, randomized clinical trial. Block randomization was used to assign 50 patients to two groups of paracetamol and ibuprofen. In the paracetamol group, subjects received 15 mg/kg oral paracetamol 30 minutes before the induction of anesthesia, followed by the same dosage every 6 hours postoperatively. Meanwhile, the ibuprofen-treated group took 10 mg/kg oral ibuprofen 30 minutes before and every 6 hours after the operation. The subjects in both groups received the medication for three postoperative days. The postoperative pain score was assessed 6 hours after the surgery and during the second and the third postoperative days. Nausea and vomiting episodes were recorded in the first postoperative day and first postoperative week. RESULTS: Based on the results, intraoperative and postoperative bleeding in both groups was not significantly different. The mean score of pain in the first postoperative day (6 hours after the surgery) and the second and the third postoperative days did not show any statistical difference. The ibuprofen group experienced fewer vomiting episodes, compared to the paracetamol group during the first postoperative day (P=0.011). Vomiting episodes in the first postoperative week did not illustrate any significant difference. CONCLUSION: As evidenced by the results of the current study, Ibuprofen had the same effect on the alleviation of postoperative pain, caused fewer vomiting episodes, and did not cause excessive bleeding as an NSAID. Therefore, oral administration of ibuprofen is suggested for pain relief and management of other complications following adenotonsillectomy in children.
RESUMO
OBJECTIVE: The aim of this study was to assess aesthetic result and parents' satisfaction of primary rhinoplasty in unilateral incomplete cleft lip patients. METHODS: Thirty-two consecutive unilateral incomplete cleft lip nose patients were operated in the tertiary hospital from 2012 to 2014. Primary rhinoplasty was done following the principle of the modified McComb repair. Nostril height, dome height, alar base width, nostril height to width ratio, dome height to nostril width ratio, nasolabial angle and columella deviation were measured on preoperative and 4-year postoperative photographs. Visual analogue scale (VAS) was assessed for each parent before the surgery and 4-year postoperatively. RESULTS: The preoperative and postoperative photographic analysis revealed significant improvement in nostril height ratio and dome height ratio. Nostril height to width ratio and dome height to nostril width ratio significantly increased. Alar base width significantly decreased. The nasolabial and columella deviation angles improved significantly. The mean parent-related satisfactory assessment based on the VAS showed statistically improved scores postoperatively. CONCLUSION: We believe this technique with minimal dissection could improve symmetry and satisfaction, although every individual surgeon could choose his preferable technique based on the components of correction that he is capable of executing reliably while considering the long-term outcomes.

INTRODUCTION: This study aimed to assess the long-term effects of postoperative debridement on the 4th and 8th postoperative weeks versus no debridement in terms of subjective and objective outcomes. MATERIALS AND METHODS: The statistical population of this study (n=80) consisted of 40 patients having chronic rhinosinusitis with nasal polyposis (CRSwNP) and 40 patients having chronic rhinosinusitis without nasal polyposis (CRSsNP). These samples were randomly divided into two groups of debridement and control. RESULTS: According to the results, 8 weeks after endoscopic sinus surgery (ESS), the 22-item Sino-Nasal Outcome Test questionnaire score (P =0.03), Lund-Kennedy score (P<0.001), nasal blockage (P=0.02), and loss/decrease in sense of smell (P=0.02) in CRSwNP were significantly lower in the debridement group than in the control group. Moreover, 6 months after ESS, in both CRSwNP and CRSsNP, no significant difference was observed between the two groups considering the outcomes (P>0.05). CONCLUSION: This study showed that debridement could lead to short-term improvements in CRSwNP patients; however, no long-term benefit was observed.
RESUMO
Parapharyngeal abscess is a life-threatening disease. Upper respiratory tract infection is the main cause in children. We present a 15-month-old boy admitted to the emergency ward with the chief complaint of difficulty in breathing caused by parapharyngealabscess. His condition deteriorated gradually, and he transferred to the operation theater quickly for abscess drainage and because of the difficulty in orotracheal intubation; a tracheostomy was performed. His respiratory condition deteriorated 2 days after PICU admission, and the medical team noticed an unexplainable respiratory distress. A chest x ray obtained and showed a right side pneumothorax and subcutaneous emphysema around theneck area. The case presented here, had not been diagnosed at the first examination; however, there were enough clinical clues (such as respiratory distress, drooling, torticollis, bulging of theneck, previous viral respiratory infection, possible pharyngeal trauma). The story of this case reminds us the importance of the precise physical exam and history taking which could be life-saving.

The aim of this article was to evaluate the expression of E-cadherin and CD44 adhesion molecule in oral tongue squamous cell carcinoma (SCC) since inappropriate expression of adhesion molecules raises the metastatic ability of the tumor cells. Biopsy specimens from 92 patients with tongue SCC were examined for the expression of E-cadherin and CD44 by immunohistochemistry. The relationship of immunoreactivity with tumor stage and cervical lymph node metastasis was then analyzed. Sixty-one patients (66.3%) had reduced or negative staining for CD44. Weak or absent staining for E-cadherin was seen in 14 patients (15.21%). Cervical lymph node metastasis is associated with decreased or negative staining for CD44, but no association was found between E-cadherin immunoreactivity and nodal metastasis. Our study reveals that reduced expression of CD44 could be an indicator of high invasiveness of tumor by increasing cervical lymph node metastasis.

In this study, we investigated the prevalence of human papilloma virus (HPV) infection and TP53 expression in patients with squamous cell carcinoma (SCC) of the tongue and, subsequently, its significance in cervical lymph node metastases and tumor differentiation. Sections of formalin-fixed, paraffin-embedded tissue blocks from 94 histologically confirmed tongue SCC cases were investigated in this study. Immunohistochemistry was used to study TP53 expression, and polymerase chain reaction (PCR) was performed for the detection of high risk HPV types (16 and 18). The frequency of HPV-16 and HPV-18 infection was 10.6% and 16%, respectively. Overexpression of TP53 was observed in 70.2% of patients. Young patients (aged below 45 years) comprised 20% of all patients. There was no significant association between TP53, HPV-16, or HPV 18 presence and higher stages of the tumor, tumor differentiation, or presence of nodal metastasis. Although an association between head and neck SCC and HPV infection is being recognized and reported, our data implicate that HPV infection or TP53 expression does not play a significant role in oral tongue SCC pathogenesis, differentiation, or metastasis, as seen in our patients.

BACKGROUND: The optimal method for managing a patient diagnosed with atypical squamous cells of undetermined significance (ASCUS) has not yet been established. The interim guidelines published by the National Cancer Institute suggest that a patient should be referred for colposcopy after the second ASCUS diagnosis within 2 years. AIM: To assess the significance of ASCUS in predicting the presence of underlying squamous intraepithelial lesion (SIL) of the uterine cervix. STUDY POPULATION: Women undergoing colposcopy for ASCUS cytology at a teaching hospital in Tehran University, in the years 1998-2001, considered eligible to enter this retrospective study. RESULTS: Of the 266 patients who underwent colposcopy, 28 (11%) had low-grade squamous intraepithelial lesion (LSIL), 16 (6.3%) had high-grade squamous intraepithelial lesion (HSIL) two (0.8%) had squamous cell carcinoma (SCC), and 48 (18.8%) had flat condyloma. CONCLUSION: Atypical squamous cells of undetermined significance (ASCUS) on a cervical smear is a good marker for detecting underlying SIL and condyloma. Thus, immediate colposcopy and directed biopsy are appropriate follow-up procedures.
