Objectives: To point out the radiological and audiological characteristics of a recently defined cochlear hypoplasia type: cochlear hypoplasia type 4. To describe this malformation in relation to adjacent anatomial structures within temporal bone. Material and Methods: This study was a reprospective chart review of the cochlear hypoplasia type 4 (CH-IV). Cases were selected from our departments' database and their CT and MRI images together with audiological evaluation data were revised.Inclusion criteria was having CH-IV diagnosis in at least one ear and having both CT and MRI carried out in hospital. Axial and coronal CT of the temporal bone were evaluated to delineate the features of the malformation appropriately. MRI images were reviewed to evaluate the statos of the cochlear nerve (CN). CN was evaluated on axial and especially on sagittal-oblique T2 weighted images and classified as aplastic, hypoplastic, or normal. Results: There were 26 ears with CH-IV in our database. In CH-IV; the cochlea has a normal basal turn, but middle and apical turns are severely hypoplastic and located anterior and medially rather than in their normal central position. The labyrinthine segment of the facial nerve is usually located antero-superior to the cochlea rather than in its normal location. Six (27.3%) out of 26 with CH-IV had cochlear nerve hypoplasia. Four ears had naroow IAC. On axial CT scan; facial recess was evaluated also. An imaginary line crosses from the mastoid segment of the facial nerve to the basal turn and round window was created. In CH-IV cases; mastoid segment was anterior to this line. In transmastoid approach; exposure of the round window might be difficult because of this rotational malformation. 22 ears (84.6%) anomalous route of the labyrinthine segment of the facial route. In those cases labyrinthine segment was anterosuperoriorly displaced. 7.7% of the cases had slight to mild hearing loss(HL), 46.2% had moderate to moderately severe HL and 46.2% had severe to profound HL. Some selected cases did not require hearing aids and cochlear implantation. As the number of turns are smaller with narrower scalae, it is strongly advisable to use thin and shorter electrodes. Thick and long electrodes may not be inserted fully into the cochlea. It is important to diagnose CH-IV since the visualization of round window may be challenging and this anomaly has diverse audiological features which directly affect the treatment plan.

Nasal tip surgery is a crucial aspect of rhinoplasty in which suture techniques play a significant role. Early suturing techniques focused primarily on repositioning alar cartilage remnants after they had undergone significant resection. The size, contour, and orientation of the medial and lateral crura are primary factors in creating a tip shape. In this review, we retrospectively evaluated obliquely oriented dome sutures with triangular dome resection that was performed in 540 rhinoplasty cases at Yunus Emre Hospital between 2015 and 2020. Dome-defining sutures were placed, and a triangular cartilage resection was performed. Subsequently, oblique sutures were placed to achieve the desired lateral cartilage position. Objective assessment of postoperative results (Objective Rhinoplasty Outcome Score), patient satisfaction assessments, and nasal examinations were conducted. The objective assessments of the esthetic results showed a significant improvement, with a mean score of 3.6, which represents a good to excellent outcome. Most patients were subjectively satisfied with the surgical outcomes of rhinoplasty. No serious complications, such as infection, recurrence of deviation, nasal obstruction, or esthetic problems such as dorsal irregularities, were observed after surgery. Overall, suturing techniques play an important role in determining the nasal tip shape. Our technique is beneficial for maintaining a favorable lateral crural position, leading to improved patient satisfaction., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 by Mutaz B.

Objective: To investigate subjective throat symptoms with the Qualities of Sore Throat Index (QuaSTI) in adults with nasal septum deviation., Study Design: Prospective study., Setting: Baskent University Ankara Hospital., Methods: Group 1 included patients with septum deviation. Preoperative data were obtained through evaluation of subjective nasal obstruction with the NOSE (Nasal Obstruction Symptom Evaluation) and throat symptoms with the QuaSTI (group 1a). After 3 months, the same patient group was reevaluated with the NOSE and QuaSTI to obtain postoperative data (group 1b). Group 2 was formed of healthy volunteers with no nasal obstruction., Results: The mean ± SD and median (range) values of the QuaSTI total score were 33.39 ± 29.50 and 18.5 (0-90) in group 1a, 7.49 ± 4.31 and 7 (0-18) in group 2, and 7.58 ± 9.24 and 4.50 (0-49) in group 1b (group 1a vs 2, P < .001; group 1a vs 1b, P < .0001). A significant difference was determined between groups 1a and 2 with respect to the QuaSTI sensory score (26.58 ± 23.54 and 18 [0-73] vs 6.51 ± 3.58 and 7 [0-15], P < .001, respectively) and between groups 1a and 1b for the QuaSTI functional score (6.03 ± 6.62 and 3 [0-20] vs 1.50 ± 2.47 and 0.50 [0-13], P = .004). No significant difference was found between groups 1a and 2 in terms of the QuaSTI emotional score (P = .126)., Conclusion: Various persistent sensory and functional throat symptoms can be seen in patients experiencing nasal obstruction associated with septum deviation, and the majority of these symptoms recover after septal surgery., (© 2022 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

Objectives: A low Neutrophil Lymphocyte Ratio (NLR) has been shown to be associated with good prognosis in Bell's Palsy (BP). However, the effect of chronic diseases that may affect the NLR, including Diabetes Mellitus (DM), has not been clarified in this context. This study aimed to evaluate the relationship between NLR and Mean Platelet Volume (MPV) in BP according to whether it is accompanied by DM, and their relationship with prognosis., Methods: A prospective observational study was conducted from May 2014 to May 2020 in a tertiary referral center, of all 79 consecutive participants diagnosed with BP in department of otolaryngology and 110 consecutive healthy participants admitted to the check-up unit. Patients diagnosed with BP were divided into two groups according to whether they were diagnosed with DM: diabetic BP patients (DM-BP, n = 33) and non-diabetic BP patients without any chronic disease (nonDM-BP, n = 46). Neutrophil (NEUT) and Lymphocyte (LYM) counts, and Mean Platelet Volume (MPV) were assessed from peripheral blood samples, and the NLR was calculated. Prognosis was evaluated using the House-Brackmann Score (HBS) six months after diagnosis., Results: The mean NLR was 2.85 ± 1.85 in BP patients and 1.69 ± 0.65 in the control group. The mean NLR was significantly higher in BP patients than healthy controls (p < 0.001). The mean NLR was 2.58 ± 1.83 in the nonDM-BP group, 3.23 ± 1.83 in the DM-BP group, and 1.69 ± 0.65 in the control group. The NLR was significantly higher in the nonDM-BP and DM-BP groups than in the control group (p < 0.05). The recovery was 90% according to the HBS. The optimal cut-off value was 2.41 (p = 0.5)., Conclusion: The NLR was increased in both diabetic and non-diabetic BP and had similar prognostic value in predicting the HBS before treatment in diabetic and non-diabetic patients with BP. MPV wasn't significantly different in diabetic and non-diabetic BP patients compared with the normal population., (Copyright © 2021 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Purpose: The role of surgery in managing perianal abscesses in the pediatric population is debatable, and data on recurrence risk is rare. This study aimed to evaluate the efficiency of surgery for a perianal abscess in children and identify parameters that predict recurrence., Methods: We performed a retrospective review of all children younger than age 14 requiring surgery for a perianal abscess from 2000 to 2018., Results: Out of 103 enrolled patients, 27 (26%) had recurrent perianal disease. Recurrences appeared after a median of 5 months (range: 1-18 months), in 12 cases as perianal abscess and 15 cases as fistula in ano . Anal fistula probing was performed in 33% of all patients, of which 16 (15%) underwent fistulotomy. In univariate analysis, older age ( p  = 0.034), fistula probing ( p  = 0.006) and fistulotomy ( p  = 0.009) was associated with treatment success. History of perianal abscess, multilocal occurrence, and the presence of enteric flora in wound swabs was associated with treatment failure ( p  = 0.002, OR = 0.032). In multivariate analysis, anal fistula probing was independently associated with treatment success ( p  = 0.019, OR = 22.08), while the history of perianal abscess was associated with treatment failure ( p  = 0.002, OR = 0.032)., Conclusion: Our study identified probing for fistula as a predictor of therapy success, while the history of perianal abscess was identified as a predictor of treatment failure. Therefore, in all children with perianal abscess, fistula probing and if present, fistulotomy should be performed., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2022 Doerner, Seiberth, Jafarov, Zirngibl and Boenicke.)

Background: Both the Dix-Hallpike test and the supine head-roll test can provoke positional nystagmus in a group of benign paroxysmal positional vertigo patients, including but not limited to those with multiple canal involvement. This study aimed to determine the incidence and interpret the clinical significance of positional nystagmus provoked by both the Dix-Hallpike and the supine head-roll tests., Methods: The results of video-nystagmography sessions recorded in the computer database that included both the Dix-Hallpike and the supine head-roll tests were examined., Results: The records belonging to 2880 video-nystagmography sessions of 2387 patients were examined. Nystagmus was detected in both the Dix-Hallpike and the supine head-roll tests of 131 (5.5%) patients. The video images belonging to 142 session records of 122 patients were accessed and further analyzed. The diagnosis was posterior canal BPPV in 9.0%, and lateral canal BPPV in 62.3%. More than one canal was involved in 3.3%, one rehabilitation maneuver was performed in 75.0%, and recurrence was observed in 7.4% of those patients., Conclusion: In both geotropic and apogeotropic variants of lateral canal BPPV, nystagmus can be observed during the Dix-Hallpike test in addition to the supine head-roll test. In patients with posterior canal benign paroxysmal positional vertigo, nystagmus can also be observed in the head-roll test. To reach a correct and comprehensive diagnosis and apply appropriate treatment in benign paroxysmal positional vertigo, the Dix-Hallpike test and the head-roll test should be completely performed on both sides, and the results of those tests must be interpreted concomitantly.

Pharyngeal aberrant internal carotid artery (PAICA) has been reported to be a cause of oropharyngeal dysphagia (OD) in case reports. However, as there have been no clinical studies, the relationship between PAICA and OD is not clear. The aim of this study was to investigate the perception of OD in elderly PAICA patients using the Eating Assessment Tool-10 (EAT-10). A study group (Group 1) was formed of patients diagnosed with PAICA from the visualization of a pulsatile mass in the pharynx in flexible fiberoptic endoscopic examination and carotid magnetic resonance angiography tests, and a control group (Group 2) was formed of age-matched healthy volunteers. The study group was subdivided as patients with unilateral PAICA (Group 1a) and patients with bilateral PAICA (Group 1b). The Turkish version of the EAT-10 was applied to all the participants. Total EAT-10 points of ≥ 3 were accepted as abnormal. Normal (< 3) and abnormal (≥ 3) total EAT-10 points were determined in 88.9% (24/27) and 11.1% (3/27), respectively, of the control group, in 55.2% (16/29) and 44.8% (13/29) of Group 1, in 70.6% (12/17) and 29.4% (5/17) of Group 1a, and in 33.3% (4/12) and 66.7% (8/12) of Group 1b. A statistically significant difference was determined between the control group and Group 1 and Group 1b in respect of abnormal (≥ 3) EAT-10 total points (p = 0.007, p = 0.001, respectively). No statistically significant difference was determined between the control group and Group 1a (p = 0.227). Problems (EAT point ≥ 1) in item 4 (swallowing solids takes extra effort) were experienced by 13 (44.8%) patients in Group 1, 9 (75%) patients in Group 1b, and 5 (18.5%) subjects in the control group (p < 0.05). These results demonstrated that unilateral PAICA does not significantly affect swallowing, whereas bilateral PAICA created a significant negative effect. These patients experience more problems when swallowing solid food., (© 2021. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Objectives: Endoscopic balloon dilatation (EBD) offers a safe and non-invasive surgical option for the treatment of subglottic stenosis. Patient selection is important to achieve good results and to detect which patients are more prone to the development of complications. The aim of this study was to determine predictors of postoperative problems and early complications in primary EBD surgeries., Methods: A retrospective analysis was made of patients with acquired subglottic stenosis who were operated on with the EBD technique between January 2010 and December 2019 in the Otolaryngology-Head and Neck Surgery Department of Baskent University Hospital. Demographic data including the age and sex of the patients were collected together with etiology, presence of chromosomal or craniofacial anomaly (C/CA), duration of prolonged intubation (DPI), and extubation dilatation timeframe (EDT). Intra and postoperative follow-up data were recorded of the need for intubation or tracheotomy, development of desaturation, and grade and type of stenosis., Results: The male to female ratio was 2:1. The patients comprised 42 males and 22 females with a mean age of 296.52 ± 551.93 days. The cause of prolonged intubation was surgery for congenital heart disease in 50 (78.1%) patients and prematurity in 14 (21.9%). The type of lesion was acute granulation in 44 (72.1%) and chronic granulation in 17 (27.9%) patients. C/CA was determined in 13 patients, the mean grade of stenosis was 76.33 ± 15.21%, mean DPI was 25.25 ± 35.49 days, and mean EDT was calculated as 78.23 ± 373.82 days. Desaturation following endoscopic balloon dilatation developed in 26 (40.6%), orotracheal intubation was required in 10 (15.6%), tracheotomy in 10 (15.6%), and cardiopulmonary arrest occurred in 4 (6.25%). Prematurity, a longer duration of preoperative intubation, longer time from extubation to dilatation, older age, and higher grade of stenosis were determined as factors associated with postoperative early respiratory complications., Conclusion: EBD indication should be carefully considered in children with acquired subglottic stenosis. To achieve better results and minimise complications, EBD should be performed without delay., (© 2021.

Background: The effect of postmenopausal osteoporosis on the middle ear mechano-acoustic system is unknown. The aim of this study is to investigate whether or not middle ear resonance frequency is affected in females with postmenopausal osteoporosis., Methods: The study included postmenopausal women aged 45-60 years, separated into 2 groups as females with postmenopausal osteoporosis and healthy postmenopausal females (control group). A detailed anamnesis was taken from all subjects and then the ear, nose, and throat examinations were done followed by pure tone audiometry, tympanometry, and multifrequency tympanometry tests. The groups were compared in respect of pure tone average, bone conduction threshold, RF, static admittance, and tympanometric peak pressure values., Results: The mean age of the patients was 59.2 ± 4.53 years (range, 48-65 years) in the postmenopausal osteoporosis group and 57.11 ± 4.27 years (range, 48-65 years) in the control group (P > .05). The mean resonance frequency values for the postmenopausal osteoporosis and control group were 954.41 ± 127.47 and 935.29 ± 126.39 Hz (P > .05 ). The mean static admittance values for the postmenopausal osteoporosis and control group were 0.82 ± 0.33 and 0.85 ± 0.3 mmho, and mean tympanometric peak pressure values were -7.35 ± 18.52 and -6.94 ± 19.52 daPa (P > .05 for both static admittance and tympanometric peak pressure). The mean pure tone averagevalues for the postmenopausal osteoporosis and control group were 20.96 ± 6.82 and 15.60 ± 7.81 dB, and mean bone conduction threshold values were 17.57 ± 6.03 and 12.10 ± 6.52 dB (P < .05 for both pure tone average and bone conduction threshold)., Conclusions: The results showed that the middle ear resonance frequency values were not affected in postmenopausal osteoporosis patients, but there was seen to be greater sensorineural hearing loss in females with postmenopausal osteoporosis compared to healthy postmenopausal females.

The purpose of this study to compare lacrimal sac flap preserving techniques with or without fibrin glue in patients undergoing endoscopic endonasal dacryocystorhinostomy. A retrospective study included 132 patients who underwent unilateral endonasal dacryocystorhinostomy between February 2011 and March 2016. Patients were divided into 2 groups: the nonfibrin glue group (n = 66) and fibrin glue anastomosis group (n = 66). Surgical success was defined as the patients' subjective report of relief of epiphora and objective endoscopic confirmation of ostium patency confirmed by a positive functional dye test. These parameters were compared between the 2 groups. Both groups were similar, in terms of demographic and clinical characteristics. The surgical success rate was significantly higher in the fibrin glue anastomosis group (95.5%) than in the nonfibrin glue group (84.8%; P = .041). Complication rate was 6.1% in the nonfibrin glue group, whereas in the fibrin glue anastomosis group, it was 4.5%. The complication rate was similar in both groups ( P = .99). Creation of an anastomosis between the lacrimal sac flaps and the nasal mucosa using fibrin glue improves the outcome of endonasal endoscopic dacryocystorhinostomy.

Objective: The aim of this study is to determine the effectiveness of coblation midline glossectomy for obstructive sleep apnea (OSA) when used as an isolated procedure. We also aim to compare the effect of this surgical procedure on supine and non-supine apnea., Materials and Methods: The medical records of patients who underwent isolated tongue base surgery as a part of step-wise surgeries between January 2014 and February 2019 are retrospectively reviewed. Pre-operative and post-operative Epworth sleepiness score (ESS), body mass index (BMI), and polysomnographic data, including the apnea-hypopnea index (AHI), oxygen desaturation index (ODI), supine AHI, and non-supine AHI of the patients were compared., Results: The study included 29 patients (26 male and 3 female). AHI improved significantly, decreasing from 34.9 ± 20.9 to 25.8 ± 17.6. Supine AHI decreased from 62.55 ± 28.23 to 55.18 ± 31.67 post-operatively, but this decrease was not significant. Non-supine AHI decreased significantly from 22.49 ± 24.02 to 14.08 ± 17.46. ESS and ODI also improved significantly., Conclusion: Coblation midline glossectomy is an effective surgical procedure when applied solely, with a success rate of 52%. Non-supine apnea benefits to a greater degree than supine apnea from this surgical procedure., Competing Interests: Declaration of Conmpeting Interest The authors have declared that there are no competing interests., (Copyright © 2020.

Background: The aim of this study was to analyze the effect of device-dependent factors on epistaxis episodes comparing patients supported with a continuous-flow left ventricular assist device (CF-LVAD) to patients under the same antithrombotic therapy., Methods: Patients who underwent CF-LVAD between 2012 and 2018 were reviewed retrospectively from the institutionally adopted electronic database. Patients who underwent mitral valve replacement (MVR) surgery receiving the same anticoagulant and antiaggregant therapy were included as a control group. Demographics, epistaxis episodes, and nonepistaxis bleeding between the two groups were compared., Results: A total of 179 patients met the inclusion criteria (61 patients CF-LVAD group, 118 patients MVR group). The median (range) follow-up periods for the study (CF-LVAD) and control (MVR) groups were 370 (2819) and 545.70 (2356) days, respectively. There was a significant difference for frequency of bleeding episodes per month between CF-LVAD and MVR groups (p = 0.003 < 0.05). The most common site of bleeding was the anterior septum in both groups (90.9% for the CF-MVR group and 100% for the MVR group). While 14 patients (23%) had nonepistaxis bleeding in the CF-LVAD group, only two patients (1.7%) had nonepistaxis bleeding in the MVR group. There were significant differences in nonepistaxis bleeding rates between the CF-LVAD and MVR groups (χ 2 =19.79, p < 0.001)., Conclusion: Both epistaxis and nonepistaxis bleeding rates were higher in the CF-LVAD group than in the MVR group. This suggests that the use of CF-LVAD support could directly increase the risk of hemorrhagic complications., Level of Evidence: 2A (Etiology/Harm).

Background: Following open rhinoplasty, a postoperative scar at the columellar incision line is a common morbidity. The aim of this study is to compare absorbable and nonabsorbable suture materials which had been used for closing the transcolumellar incision, in the aspect of risk of postoperative infection, wound healing, postoperative columellar scar and patient satisfaction., Method: A prospective, randomized, single-blind study was conducted between May 2017 and February 2018. Sixty-four rhinoplasty patients were randomly assigned to absorbable (n = 32) or nonabsorbable (n = 32) groups. The columellar incision was closed with 7 full-thickness skin sutures. Either nonabsorbable 6/0 polypropylene (Group 1) or absorbable 6/0 polyglytone 6211 (Group 2) sutures were placed at the columellar incisions. Polypropylene sutures were removed at the 7th postoperative day. A Mann-Whitney U test and Monte Carlo were used for statistical comparison. Photographs of the patients at the postoperative third month (Fig. 2) were evaluated and scored in terms of scarring, pigmentation, notching, level differences in the incision area by two different otorhinolaryngologists who did not know the randomization. Suture removing discomfort was assessed with visual analogue scale scores. A satisfaction survey was filled out by all the patients completing their third month after the operation., Results: According to the results of both otorhinolaryngologists, there was no significant difference between the two groups in terms of pigmentation, level difference, notching, overall appearance and total score (p = 0.920, p = 0.498, respectively). The mean score on the Wong-Baker scale was 3.19 ± 1.67 in group 1. In the Satisfaction Survey, the average score of the group 1 was 6.90 ± 3.24, while the mean score of the group 2 was 7.062 ± 2.77. There was no statistically significant difference between the two groups (p = 0.715)., Conclusions: Suturing inverted V transcolumellar incisions with rapid resorbable sutures caused significantly less discomfort but no difference in scarring compared to nonresorbable sutures as evaluated by patients and observers., Level of Evidence Iii: This journal requires that authors assign a level of evidence to each article.

Background: The age at which nasal tip support changes start to occur is unknown. Evaluation of nasal tip support is difficult, especially as the ideal nasal tip support pressure remains elusive. The aim of this study is to determine the nasal tip support pressure alterations relative to age and sex., Objectives: The aim of this study is to determine the changers in resistance of the nasal tip support in relation to age and sex., Methods: This prospective clinical study was conducted between January and April 2019 at a tertiary health facility. Nasal tip resistances were measured in four different age-groups (20-29, 30-39, 40-64, and > 65 years) with a digital Newton meter. A total of 159 patients with a minimum of 36 patients per group were included in the study. Nasal tip resistance measurements were compared among nasal tip displacement distances of 2, 3, and 4 mm, focusing on age and sex., Results: The nasal tip resistance of the 20-29 age-group was significantly higher at 2, 3, and 4 mm nasal tip displacement distances, when compared with the 30-39 and 40-64 age-groups, whereas compared to the > 65 years group, it was significantly higher at 3 and 4 mm nasal tip displacement distances (p < 0.005). Nasal tip resistance of males was found to be significantly higher than that of females, at 3 and 4 mm nasal tip displacement distances (p < 0.001)., Conclusions: Nasal tip resistance is higher in males and universally decreases significantly after 30 years of age while remaining constant at later ages. Therefore, surgeons should prefer nasal tip resistance increasing techniques in the rhinoplasty operations that are performed on patients even from early years of age, in order to maintain and strengthen the nasal tip resistance., Level of Evidence Iv: This journal requires that authors assign a level of evidence to each article.

Background: Positional nystagmus elicited by the Dix-Hallpike maneuver often reverses its direction as the patient is re-seated from the provoking head hanging position. The incidence of reverse nystagmus and its association with prognosis in posterior canal benign paroxysmal positional vertigo (pcBPPV) is not clear., Objective: To determine the incidence of upright positioning-related reverse nystagmus and its association with the success of canalith repositioning (Epley) maneuver (CRM) treatment in pcBPPV., Methods: The records of patients that had been tested with video-nystagmography in a tertiary care center, between October 2016 and March 2019, were reviewed. Data were obtained from detailed analysis of video recordings of 321 patients with typical pcBPPV., Results: Reverse nystagmus was determined in 85% of the patients with pcBPPV. The number of CRMs required for treatment was lower in patients with reverse nystagmus (1.32±0.68) compared to patients without reverse nystagmus (1.81±0.98) (p < 0.001). There was not a statistically significant relationship between reverse nystagmus and recurrence (p = 0.623)., Conclusions: The absence of reverse nystagmus on upright positioning during the Dix-Hallpike test predicts poor success for the CRM, as repetitive repositioning maneuvers might be required to achieve successful treatment in pcBPPV.

Colon cancer (CC) and rectal cancer (RC) are synonymously called colorectal cancer (CRC). Based on our experience in basic and clinical research as well as routine work in the field, the term CRC should be abandoned. We analyzed the available data from the literature and results from our multicenter Research Group Oncology of Gastrointestinal Tumors termed FOGT to confirm or reject this hypothesis. Anatomically, the risk of developing RC is four times higher than CC, while physical activity helps to prevent CC but not RC. Obvious differences exist in molecular carcinogenesis, pathology, surgical topography and procedures, and multimodal treatment. Therefore, we conclude that CC is not the same as RC. The term "CRC" should no longer be used as a single entity in basic and clinical research as well as other areas of classification.

Purpose: Heart rate variability (HRV) is a noninvasive and sensitive method used to evaluate autonomic function of the heart based on specific polysomnographic parameters. This study aimed to determine the effect of expansion sphincter pharyngoplasty (ESP) on HRV and the apnea-hypopnea index (AHI) in patients with obstructive sleep apnea (OSA)., Materials and Methods: This retrospective cohort study included patients who presented to the Department of Otorhinolaryngology, Hacettepe University Hospital (Ankara, Turkey), were diagnosed with OSA, and underwent ESP. Patient medical records, including demographic data, polysomnographic findings, and HRV parameters, were reviewed. The predictor variable was the effect of ESP on the AHI and the primary outcome variables were HRV parameters. Descriptive and bivariate statistics were computed using χ 2 test, t test, and Mann-Whitney U test., Results: The mean age of the 28 patients (20 men and 8 women) was 43 ± 9.9 years. Surgical success (AHI, <20; 50% decrease in the AHI) was achieved in 16 patients (57.1%). The AHI decreased in 22 patients (78.6%) but increased in 6 patients (21.4%) after ESP. The ratio of low-frequency power (LF) to high-frequency power (HF) decreased significantly in the patients with successful surgery and in those whose AHI decreased after surgery (P = .02 and P = .001, respectively). For the change in the LF/HF ratio, 19 patients had a decrease in sympathetic activity, whereas 9 had an increase in sympathetic activity, after ESP. A decrease in sympathetic activity after ESP was significantly associated with surgical success and a decrease in the AHI (P = .033 and P = .001, respectively)., Conclusion: ESP is an effective surgical option for the treatment of OSA and lowers the AHI. Successful ESP plays a role in decreasing sympathetic activity of the heart, which might be associated with a decrease in the risk of cardiovascular disease., (Copyright © 2017 American Association of Oral and Maxillofacial Surgeons.

Objective: The aim was to evaluate surgical techniques and their relationship to postoperative success rate and hearing outcomes in acquired atresia of the external auditory canal., Materials and Methods: In this article, 24 patients with acquired atresia of the external auditory canal were retrospectively evaluated regarding their canal status, hearing, and postoperative success., Results: Acquired stenosis occurs more commonly in males with a male: female ratio of 2-3:1; it seems to be a disorder affecting young adults. Previous ear surgery (13 patients, 54.2%) and external ear trauma (11 patients, 45.8%) were the main etiological factors of acquired ear canal stenosis. Mastoidectomy (12/13) and traffic accidents (8/11) comprise the majority of these etiological factors. Endaural incision is performed in 79.2% and postauricular incision for 20.8% of cases during the operation. As types of surgical approach, transcanal (70.8%), transmastoid (20.8%), and combined (8.4%) approaches are chosen. The atretic plate is generally located at the bony-cartilaginous junction (37.5%) and in the cartilaginous canal (33.3%); the bony canal is involved in a few cases only. Preserved healthy canal skin, split- or full-thickness skin grafts, or pre- or postauricular skin flaps are used to line the ear canal, but preserved healthy canal skin is preferred., Conclusion: The results of surgery are generally satisfactory, and complications are few if surgical principles are followed.
