A novel technique with butterfly splint for middle turbinate stabilization in sinus surgery.

OBJECTIVE: To assess the efficacy of newly designed butterfly splint with special technique for middle turbinate stabilization in preventing adhesion following bilateral endoscopic sinus surgery (ESS) for chronic rhinosinusitis with nasal polyps (CRSwNP). STUDY DESIGN: Prospective, double-blind, randomized controlled. SETTING: University hospitals. METHODS: Following ESS, in cases of traumatized and/or unstable middle turbinates, newly designed butterfly plastic splint was randomly inserted in the middle meatus of one nasal side, while no splint was inserted in the other (control). Patients were followed up on after 1 week, 1 month, and 6 months. Endoscopic examination and a visual analog scale were used to evaluate each side of the nasal cavity for adhesion, crusting, pus, pain, nasal obstruction, and nasal discharge. RESULTS: Thirty patients (60 nasal sides) were included. For all investigated parameters, there was no significant difference between the splinted and non-splinted sides at the first week visit. Adhesion was found significantly less in the splinted sides (3%) than the non-splinted sides (27%) after 1 month (P = 0.038). The adhesion rate in the splinted sides remained 3% at the 3 month follow-up visit, however, in the non-splinted sides, the rate increased up to 30% (P = 0.007). Throughout the follow-up visits, all other investigated parameters remained statistically insignificant between both sides. CONCLUSIONS: The newly designed butterfly plastic splints to avoid middle turbinate adhesion is safe and effective in both reducing middle meatal adhesion with low complication rate in CRSwNP patients undergoing ESS and middle turbinate stabilization in its intermediate position.

Minimally Anterior Medial Maxillary Approach (MAMMA): a novel technique for a wide access to the maxillary sinus.

PURPOSE: To describe a novel endoscopic technique to approach the maxillary sinus (MS), the Modified Anterior Medial Maxillary Approach (MAMMA), preserving the inferior turbinate (IT) and the nasolacrimal duct (NLD). To perform radiological measurements and describe a case series to study the feasibility and limits of MAMMA. METHODS: Computed tomography (CT) scans (n = 150 nasal cavities) were used to calculate areas of the MAMMA to define surgical limits and extensions. Measurement of distances to critical anatomy landmarks and total area for the MAMMA were calculated. An instructional case illustrating the surgical technique and outcome was also included. RESULTS: Radiological analysis showed a mean distance from the Piriform Aperture (PA) to the anterior limit of the NLD of 1.03 ± 0.18 cm (range 0.59-1.48) and a mean distance from de PA to the posterior limit of the NLD of 1.57 ± 0.22 cm (range 1.02-2.11). The mean distance from the nasal floor to the Hasner's valve was 1.61 ± 0.27 cm (range 1.06-2.52) and the distance from the nasal floor to the insertion of the IT was 2.20 ± 0.36 cm (range 1.70-3.69). Finally, the mean total area for the MAMMA was 4.04 ± 0.52 cm2 (range 3.17-5.53). No complications or recurrence of the pathology were observed in operated patients. CONCLUSION: The MAMMA provides a wide surgical field of the MS walls comparable to more aggressive techniques, with preservation of the sinonasal and lacrimal function. MAMMA is an effective alternative to treat different MS pathologies including benign recurrent maxillary sinus tumors.

[Intraosseous cavernous hemangioma of the middle turbinate. Clinical cases]. / Vnutrikostnaya kavernoznaya gemangioma srednei nosovoi rakoviny. Klinicheskie sluchai.

Intraosseous vascular pathology of the turbinates is extremely rare in the practice of an otorhinolaryngologist and can be presented in various histopathological variants. The article presents two clinical cases in which an intraosseous cavernous hemangioma was hidden under the mask of a hypertrophied middle turbinate. The final diagnosis was established by the results of histological examination. The analysis of these clinical cases indicates that, despite the low prevalence, atypical clinical and CT picture, intraosseous formations of the nasal cavity can be of a vascular nature and certainly require a comprehensive examination, including CT, CT with contrast and/or MRI of the nose and paranasal sinuses. These clinical observations indicate that preliminary embolization of feeding vessels before surgical treatment is not required.

A Patient of Venous Hemangioma of the Inferior Turbinate.

Sinonasal hemangiomas are relatively rare among the hemangiomas that occur from the head and neck parts. According to their histopathologic findings, they are classified as capillary, cavernous, or venous type. Some cases of capillary or cavernous hemangioma that occur from the inferior turbinate have been reported. However, there was no reported case of venous hemangioma arising from the inferior turbinate. We present a case of 67-year-old male who has venous hemangioma of the left inferior turbinate whose initial symptoms were watery rhinorrhea and postnasal drip. With this study, although uncommon, venous hemangioma should be considered as a differential diagnosis in patient with mass lesion of the inferior turbinate.

Cultured Mesenchymal Cells from Nasal Turbinate as a Cellular Model of the Neurodevelopmental Component of Schizophrenia Etiology.

The study of neurodevelopmental molecular mechanisms in schizophrenia requires the development of adequate biological models such as patient-derived cells and their derivatives. We previously utilized cell lines with neural progenitor properties (CNON) derived from the superior or middle turbinates of patients with schizophrenia and control groups to study schizophrenia-specific gene expression. In this study, we analyzed single-cell RNA seq data from two CNON cell lines (one derived from an individual with schizophrenia (SCZ) and the other from a control group) and two biopsy samples from the middle turbinate (MT) (also from an individual with SCZ and a control). We compared our data with previously published data regarding the olfactory neuroepithelium and demonstrated that CNON originated from a single cell type present both in middle turbinate and the olfactory neuroepithelium and expressed in multiple markers of mesenchymal cells. To define the relatedness of CNON to the developing human brain, we also compared CNON datasets with scRNA-seq data derived from an embryonic brain and found that the expression profile of the CNON closely matched the expression profile one of the cell types in the embryonic brain. Finally, we evaluated the differences between SCZ and control samples to assess the utility and potential benefits of using CNON single-cell RNA seq to study the etiology of schizophrenia.

Diode laser-assisted inferior turbinoplasty in resistant cases of allergic rhinitis: a clinical and histopathological study.

Chronic nasal obstruction owed to inferior nasal turbinate hypertrophy is one of the most common problems encountered in rhinology. When medical management fails, surgical reduction of hyperplastic inferior nasal turbinate is often used. Diode laser is appropriate for the use in the nasal turbinate. This study was designed to define the histopathologic changes in the inferior turbinate post diode laser turbinoplasty and evaluate the outcome in patients having allergic inferior turbinate hypertrophy that has not responded to the medical treatment. A prospective single-cohort study was carried out. Under general anesthesia, 18 patients underwent inferior turbinoplasty using diode laser 980 nm in the contact mode submucosally under guidance of a 4-mm nasal endoscope 0°. Inferior turbinate mucosa biopsy specimens were taken at the time of surgery, and after 3 months, they were histopathologically examined with assessment of the patients' symptoms. At 3 months postoperatively, histopathologic assessment demonstrated marked structural changes in diode laser-treated inferior turbinates including the predominance of fibrous tissue with diminution of seromucinous glands, venous sinusoids, and inflammatory cell infiltrate. Concurrently, 16 patients (89%) had no nasal obstruction, 15 patients (83%) had moderate-to-good improvement of rhinorrhea, whereas 13 patients (72%) had moderate-to-good improvement of sneezing. Diode laser produces histopathologic changes in the inferior turbinate soft tissues, providing excellent ablation of the soft tissue with controllable performance and good hemostasis. Therefore, it is a safe, minimally invasive, and effective procedure in relieving nasal obstruction secondary to inferior turbinate hypertrophy as well as other symptoms of allergic rhinitis.

Nasal airway obstruction and orofacial pain: a multicenter retrospective analysis.

The aim of this study was to investigate the relationship between nasal airway obstruction (NAO) and symptoms of orofacial pain, including temporomandibular joint pathology and primary headaches. This study was a retrospective analysis of consecutive patients seeking care for chronic orofacial pain at 14 North American treatment centers. The standardized evaluation protocol followed for all patients included cone beam computed tomography (CBCT), a comprehensive clinical examination, and a thorough review of the patient's subjective complaints and health history, including pain and sleep pathology. The primary conditions of interest in this study were the following 5 types of NAO: nasal valve compromise (NVC), deviated septum, septal swell body, concha bullosa, and inferior turbinate soft tissue hypertrophy. Descriptive statistics and regression analysis were performed to determine comorbidities between orofacial pain symptoms and NAO observed on CBCT images. The study population consisted of 1393 patients, 253 men (18.2%) and 1140 women (81.8%). The mean age of the patients was 43.3 (SD 18.1) years. NVC was the most prevalent type of NAO found in the study population (n = 1006; 72.2%). NVC showed a statistically significant comorbidity with capsulitis (odds ratio, 3.73) as well as facial and cervical myositis (odds ratio, 6.97). To the author's knowledge, this is first time that these comorbidities have been identified. NAO had a high comorbidity with orofacial pain. Specifically, NVC was a major contributor to NAO. An understanding of the mechanisms of orofacial pain as well as the effects of improper (mouth) breathing, adaptive forward head posture, muscular fatigue, parafunction, and temporomandibular joint pathology will help the clinician to evaluate the role a patient's nose may be playing in orofacial pain.

Treatment of inferior turbinate hypertrophy by plasma turbinate reduction with one-point-three-side way. / 一点三面法等离子鼻甲减容术治疗下鼻甲肥厚.

OBJECTIVES: Nasal congestion is often the main symptom of the patients with non-allergic rhinitis, who have inferior turbinate hypertrophy if getting poor treatment effect. Plasma treatment for inferior turbinate hypertrophy can effectively improve nasal obstruction. Generally, plasma treatment with multiple puncture sites, makes patients intraoperative painful and postoperative bleeding, which let patients often fear of surgery. Postoperative nasal adhesion or lower turbinate scar and other complications sometimes happened, and some patients still feel nasal obstruction due to severe mucosal damage and scar formation. We innovatively used one-point-three-side plasma turbinate volume reduction in the treatment of inferior turbinate hypertrophy, in order to reduce complication, improve symptoms, and enhance curative effect. METHODS: A total of 111 patients with non-allergic rhinitis with complete data due to hypertrophy of inferior turbinate and poor drug treatment from Nov. 2011 to Oct. 2019. The hypertrophic inferior turbinate of patients with non-allergic rhinitis was ablated by plasma turbinate volume reduction, and the symptom scores of patients were evaluated by visual analog scales (VAS) before surgery, 1 week, 1 month, 3 months, and 6 months after surgery. The intraoperative pain was scored by VAS. The pathological morphology of nasal mucosa was observed before and after operation in some patients. RESULTS: The nasal obstruction score of the patients was significantly lower at 1 week, 1 month, 3 months and 6 months after the operation (all P<0.05). The distribution of submucosal blood vessels and glands was improved by postoperative pathological observation. CONCLUSIONS: Plasma turbinate volume reduction with one-point-three-side is effective with minimally invasion, and less complication, which is worthy of clinical promotion.

[The septal tubercle: the state of the problem]. / Bugorok peregorodki nosa.

The septal tubercle is considered to be a thickened area of the nasal septum, which is located above the lower nasal concha and in front of the middle nasal concha. Taking into account its histological structure and location in the distal segment of the internal nasal valve, it is located and structured for secretory function and vasoactive regulation of the respiratory air flow. These histologically rich tissues with glandular elements are well adapted to the possible dryness that occurs under the influence of intense air flow during breathing, and the existence of a certain number of venous sinusoids of the blood confirms the connection with part of the extensive vascular tissues in the nasal cavity. It is believed that the tubercle of the nasal septum is more pronounced in patients with chronic inflammation of the sinonasal region, for example, with chronic allergic rhinitis or chronic rhinosinusitis. There is currently no consensus on the issue of surgery of the nasal septum body. Due to the lack of consensus among practitioners, many surgeons do not routinely perform operations on this structure and consider the surgical intervention too aggressive, and the effect on nasal obstruction is insignificant. However, according to the presented studies, the results of surgical reduction of soft tissues of the enlarged septal tubercle in the treatment of nasal obstruction using radiofrequency ablation, coblation or microdebrider seem promising, which requires additional study of this issue during long-term follow-up.

Middle turbinate handling during ESS. Our experience.

PURPOSE: The treatment of middle turbinate (MT) during endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) remains a controversial issue. Several authors recommended preservation of MT to avoid complications, but MT resection is sometimes necessary. In the last years, our group has applied an original surgical technique to preserve MT, stabilize its head and ensure patency of the ostiomeatal complex (OMC) in ESS. We herein described this approach to the MT and reported its preliminary results in terms of post-operative endoscopic features and complications. METHODS: The study retrospectively considered 34 consecutive adult patients suffering from CRS and treated with primary or revision ESS. Medialization of the MT and its stabilization to achieve post-operative patency of the OMC was obtained by means of: (i) creation of a surgically controlled synechia between the MT head and nasal septum; (ii) positioning of a silicone plate in the OMC. The silicone splints kept the MT head in an obliged position to contact the septum. RESULTS: At 12-month follow-up control, we found: (i) stabilized MT medialization in all treated cases, (ii) only one case of lateral synechia without recurrent CRS, and (iii) a polypoid recurrence rate of 13%. CONCLUSIONS: The MT handling technique during ESS herein preliminarily described seems to be an effective approach to medialize and stabilize the MT. This technique could be particularly appropriate for unstable MT after removing massive inflammatory lesions of the mucosa.

Comparison between the endoscopic scores of bolgerization versus partial resection of the middle turbinate for management of the postoperative lateralization in the early follow-up period after endoscopic frontal sinusotomy: A randomized controlled study.

BACKGROUND: Frontal sinusotomy is a challenging procedure that needs meticulous handling due to its unique anatomical position. Postoperative middle turbinate lateralization is critical comorbidity for the success rate, and many techniques are adopted to prevent it. The study aimed to compare the effect of middle turbinate bolgerization and partial resection on the postoperative endoscopic scores and assess their impact on the middle meatus and the frontal recess outcome. PATIENT AND METHODS: This prospective study was conducted on forty-one patients undergoing bilateral frontal sinusotomy for chronic frontal sinusitis. Nasal cavities were randomized so that partial middle turbinate resection technique was done alternately with bolgerization approach in every patient. Each participant acted as their control. Both sides were compared using Lund Kennedy Endoscopic Score (LKES) and Perioperative Sinus Endoscopy Score (POSE) at the baseline, 1st, 3rd, and 12th-month intervals postoperatively. Also, middle turbinate status was assessed at the end of the 12th-month interval using POSE score. RESULTS: The total frontal sinus patency rate was 82.9% (63/76 operated sinus). Baseline scores, LKES (3.79 ± 0.777 vs 4.05 ± 0.769, p = 0.142, for the side of resection and the side for bolgerization respectively) and POSE (1.79 ± 0.413 vs 1.82 ± 0.393, p = 0.777, for the side of resection and the side for bolgerization respectively). Regarding LKES, the differences between both operated sides were fluctuating with p values: 0.001*, 0.171, and 0.044* for the 1st, 3rd, and 12th months follow-up intervals, respectively. Regarding the POSE score of the frontal sinus, the difference between both groups was steadily increasing with p values: 0.318, 0.119, and 0.017* for the 1st, 3rd, and 12th months follow-up intervals. The middle turbinate's POSE score at the 12th month was significantly higher in the side allocated for bolgerization (p-value = 0.008*). CONCLUSION: Partial middle turbinate resection showed favorable endoscopic outcomes than bolgerization at the 12th month follow up period in patients undergoing primary ESS for chronic frontal sinusitis.

[Results of inferior nasal turbinate reduction in old and very old patients with chronic rhinitis]. / Ergebnisse der Nasenmuschelverkleinerung bei alten und sehr alten Patienten mit chronischer Rhinitis.

BACKGROUND: Symptoms of chronic rhinitis in old and very old populations may result from isolated hyperplasia of nasal inferior turbinates. Turbinoplasty is a possible method of treatment in these individuals. However, preoperative concerns are associated with their poor general condition: tendency to epistaxis, treatment with anticoagulants, hypertension, and less effective healing. OBJECTIVE: The aim of this study was to determine differences in results of turbinoplasty obtained in old and very old individuals with chronic rhinitis, compared to young and otherwise healthy patients. MATERIAL AND METHODS: We analyzed records of 130 patients with hyperplasia of the inferior turbinates, who had undergone bipolar diathermy turbinoplasty: 82 individuals aged 18-59 (mean = 33.8; SD = 10.2), 30 patients aged 60-74 (mean = 66.0; SD = 3.7) and 18 participants aged 75 + years (mean = 85.3; SD = 6.5). The patients were questioned about the intensity of their symptoms before and one month after the surgery, using the SNOT-20 questionnaire. The duration of wound healing and satisfaction scores were also noted. RESULTS: Nasal patency, nasal discharge and post-nasal drip improved in old and very old patients, similarly as in the young ones. Olfactory and taste function improved significantly more in young individuals. Postoperative healing time was significantly longer in very old patients. CONCLUSIONS: Some results of turbinoplasty in old and very old patients were significantly worse than in young ones.

Strong correlation between air-liquid interface cultures and in vivo transcriptomics of nasal brush biopsy.

Air-liquid interface (ALI) cultures are ex vivo models that are used extensively to study the epithelium of patients with chronic respiratory diseases. However, the in vitro conditions impose a milieu different from that encountered in the patient in vivo, and the degree to which this alters gene expression remains unclear. In this study we employed RNA sequencing to compare the transcriptome of fresh brushings of nasal epithelial cells with that of ALI-cultured epithelial cells from the same patients. We observed a strong correlation between cells cultured at the ALI and cells obtained from the brushed nasal epithelia: 96% of expressed genes showed similar expression profiles, although there was greater similarity between the brushed samples. We observed that while the ALI model provides an excellent representation of the in vivo airway epithelial transcriptome for mechanistic studies, several pathways are affected by the change in milieu.

Septoplasty with or without concurrent turbinate surgery versus non-surgical management for nasal obstruction in adults with a deviated septum: a pragmatic, randomised controlled trial.

BACKGROUND: Septoplasty (surgical correction of the deviated nasal septum) is the most frequently performed ear, nose, and throat operation in adults, but no randomised controlled trials or non-randomised comparative studies on the effectiveness of septoplasty have been published. Consequently, health-care providers, health insurance companies, and policy makers are concerned about the effectiveness of the procedure. We aimed to assess the effectiveness of septoplasty for nasal obstruction in adults with a deviated septum. METHODS: We did this open, multicentre, pragmatic, randomised controlled trial in 16 secondary and two tertiary referral hospitals in the Netherlands. Adults (aged ≥18 years) with nasal obstruction, a deviated septum, and an indication to have septoplasty done were randomly allocated (1:1) to receive either septoplasty with or without concurrent turbinate surgery or non-surgical management. Patients were stratified by sex, age (<35 years or ≥35 years), and deviation severity (mild, moderate, or severe). The primary outcome was health-related quality of life, measured with the validated Glasgow Health Status Inventory at 12 months. Analyses were done on an intention-to-treat basis. The trial is registered with the Netherlands Trial Register, number NTR3868. FINDINGS: Between Sept 2, 2013, and Dec 12, 2016, we randomly assigned 203 participants to receive either septoplasty with or without concurrent turbinate surgery (n=102) or non-surgical management (n=101). 189 participants were analysed at 12 months. At 12 months, mean score on the Glasgow Health Status Inventory of patients assigned to septoplasty was 72·2 (SD 12·2) and for those assigned to non-surgical management was 63·9 (SD 14·5, mean difference 8·3 [95% CI 4·5-12·1], favouring septoplasty). Septal abscess occurred in one surgical patient and septal perforation in two surgical patients. No side-effects of nasal medication were reported. INTERPRETATION: Septoplasty is more effective than non-surgical management for nasal obstruction in adults with a deviated septum. This effect was sustained up to 24 months of follow-up. FUNDING: The Netherlands Organisation for Health Research and Development (ZonMw).

Superior turbinate eosinophilia predicts olfactory decline in patients with chronic rhinosinusitis.

BACKGROUND: Predicting postoperative olfactory decline in patients with chronic rhinosinusitis (CRS) remains a considerable challenge. OBJECTIVE: To evaluate patterns of postoperative olfactory function in patients with CRS and explore potential predictors of postoperative olfactory decline. METHODS: A total of 76 patients with CRS electing endoscopic sinus surgery (ESS) were enrolled in this prospective study. Olfaction was assessed with Sniffin' Sticks preoperatively and 3 months postoperatively. Preoperative peripheral venous blood and superior turbinate at surgery were collected for eosinophil quantification. Olfactory cleft was evaluated by computed tomography and endoscopy. Postoperative olfactory decline was defined by a decrease in threshold-discrimination-identification (TDI) score more than 0 point. Multivariable logistic regression analysis was conducted to identify potential predictors associated with postoperative olfactory decline in TDI score. RESULTS: A total of 30.26% of patients with CRS (23/76) presented with olfactory decline 3 months post-ESS. Patients with CRS with olfactory decline showed significantly higher preoperative tissue eosinophils (P < .001), blood eosinophil count (P = .002), blood eosinophil percentage (P = .009), and preoperative TDI scores (P = .017) than patients with CRS without olfactory decline. After adjusting for patient demographics and comorbidities, the preoperative tissue eosinophilia was significantly associated with patients with CRS with postoperative olfactory decline (odds ratio = 1.103; P = .038). An absolute count of 23.5 eosinophils per high-power field in superior turbinate was the best predictor of olfactory decline with the highest area under the receiver operating characteristic curve of 0.901. CONCLUSION: Superior turbinate eosinophilia is highly associated with olfactory decline in patients with CRS 3 months after ESS.

The impact of allergies and smoking status on nasal mucosa of hypertrophied turbinates - an immunohistologic analysis.

Background: Allergies and smoking are common reasons for nasal mucosa inflammations, which in turn, cause nasal obstructions. Nevertheless, the impact of coexisting allergies and smoking on nasal mucosa inflammation has not been studied.Objectives: To study the impact of smoking with relation to allergies on nasal mucosa histology and to characterize an immunologic profile using immunohistochemical (IHC) staining.Methods: A cross-sectional study. Nasal biopsies of inferior turbinates from smokers with different allergic statuses were compared. Demographics, comorbidities, histologic, and immunohistochemical (IHC) staining of CD3, CD68, CD 20, and CD138 receptors were compared and analyzed.Results: A total of 53 patients were included, of which 20 (37.7%) were smokers, and 20 (37.7%) had allergic backgrounds. Smokers, both allergic and non-allergic, demonstrated reduced edema compared to the control group (p Value = 0.034) and significantly lower eosinophil density in the stroma compared to the allergic nonsmokers' group (p Value = 0.04). Smokers had a significant negative correlation between the number of cigarettes per day and the expression of CD20 in the stroma (-0.452, p Value = 0.045) and the epithelium (-0.432, p Value = 0.057) in IHC staining. Allergic smokers had a negative correlation (-0.705, p Value = 0.023) between the number of cigarettes per day and the CD68 marked cell expression in the epithelium.Conclusion: The coexistence of an allergic background and smoking alters known immunologic responses within the nasal mucosa. Smoking may have an immunosuppressive role in the nasal mucosa in both innate and humoral immune systems.

The osteotomy diameter in the transcanalicular laser dacryocystorhinostomy. Our experience in 192 lacrimal pathways.

OBJECTIVES: We want to evaluate the influence of the size of the osteotomy on the postsurgical outcomes. METHODS: A retrospective study was performed in patients who underwent TCL-DCR from January 1, 2008, to March 1, 2019. The patients were divided into two groups: the patients in one group were subjected to LP surgery with an osteotomy diameter equal to 9 mm ± 1 mm (group A), and the patients in the other group were subjected to surgery with an osteotomy diameter equal to 14 mm ± 1 mm (group B). RESULTS: A total of 159 lacrimal pathways (LPs) were operated on in group A with a success rate (SR) of 66.6%. Thirty-three LPs were operated on in group B with an SR of 81.8%. CONCLUSION: An osteotomy diameter equal to 14 mm ± 1 mm achieved better postoperative results than an osteotomy diameter equal to 9 mm ± 1 mm.

Comparison of the efficacy of two different local anesthetics in inferior turbinate reduction.

PURPOSE: The present study compares the local anesthetic efficacy of EMLA® cream and lidocaine injection used in the radiofrequency reduction of the inferior turbinate. METHODS: The study included a total of 124 patients with inferior turbinate hypertrophy and who underwent turbinate reduction under local anesthesia. The operations were performed 15 min after a lidocaine injection and 30 min after EMLA cream application. The respondent patients were asked to interpret such situations as intraoperative pain, discomfort during the procedure, choking sensation and difficulty swallowing using the Visual Analogue Scale (VAS). RESULTS: The EMLA cream patients (Group A) were found to have a lower level of discomfort, choking sensation and difficulty swallowing than the lidocaine patients (Group B), while there was no substantial difference in pain between the two groups. CONCLUSIONS: It is concluded that EMLA® cream is an effective alternative to lidocaine injection during inferior turbinate reduction procedures.

Postoperative pain with or without nasal splints after septoplasty and inferior turbinate reduction.

PURPOSE: To determine the effect of intranasal Doyle splints on postoperative pain following septoplasty and inferior turbinate reduction (ITR). Changes in Nasal Obstruction Symptom Evaluation (NOSE) scores were also evaluated. MATERIALS AND METHODS: A prospective cohort study conducted from January 2017 to January 2019. Patients were recruited if they experienced nasal obstruction due to septal deviation and inferior turbinate hypertrophy, and failed a one-month trial of intranasal corticosteroids. All patients underwent septoplasty with ITR, and either had Doyle splints or no splints placed. Patients were prescribed hydrocodone-acetaminophen 5-325 mg and asked to keep a daily log of pain medication use and visual analog scale (VAS) scores. Pain logs and NOSE scores were compared between patients who had splints versus patients who had no splints placed after septoplasty and ITR over the first postoperative week. NOSE scores were also collected at every postoperative visit (1 week, 1 month, and 6 months). RESULTS: Fifty-seven patients were enrolled (37 splints, 20 no-splints). The median postoperative pain VAS score was 3.0 (interquartile range [IQR] 2.0-5.0) for the splint group and 4.0 (IQR 2.0-5.0) for the no-splint group (P = 0.906). The median postoperative pain medication requirement in morphine equivalents at the first postoperative visit was 5.4 mg/day (IQR 2.0-13.3) for the splint group and 8.4 mg/day (IQR 1.8-15.3) for the no-splint group (P = 0.833). CONCLUSIONS: There were no statistically significant differences in postoperative pain VAS scores or pain medication use between the two groups. All patients experienced significant reductions in NOSE scores postoperatively.

The effect of anatomic variations and maxillary sinus volume in antrochoanal polyp formation.

PURPOSE: The antrochoanal polyp (ACP), otherwise known as the Killain polyp, is a benign lesion that originates from maxillary sinus mucosa, extending from the accessory ostium towards the middle meatus, and later tends to protrude posteriorly towards the choana and nasopharynx. Many studies have emphasized that its etiopathogenesis is unclear. Research suggests that chronic sinusitis and allergic rhinitis are factors that play an important role in the formation of ACP, as well as anatomical variations. In this study, we aimed to evaluate the effect of anatomical variations and maxillary sinus volume in patients diagnosed with anthrochoanal polyp. METHODS: Paranasal sinus computed tomography (PNS CT) images of patients with unilateral ACP patients were examined. The non-ACP sides of the patients comprised the control group. Nasal septal deviation, agger nasi cells, concha bullosa, paradoxical middle turbinate, hyperpneumotized ethmoid bulla, uncinate pathology (medialized or pneumatized uncinate), haller cell, accessory ostium, maxillary sinus retention cyst and maxillary sinus volumes were evaluated. RESULTS: The study included a total of 54 patients (33 females, 21 males). Mean patient age was 22.92 ± 13.95 (range 6-56) years. Mean maxillary sinus volume was 17.88 ± 5.16 mm3 for the ACP sides and 16.37 ± 4.55 mm3 for the non-ACP sides. Maxillary sinus volume was significantly larger in the ACP side (p = 0.000). Concha bullosa was observed on the ACP side in 23 patients (42.6%) and in the non-ACP side in 21 patients (38.9%). Agger nasi cells were observed in the ACP side in 47 patients (87.0%) and in the non-ACP side in 42 patients (77.7%). Hyperpneumatized ethmoid bulla was observed in the ACP side in 14 patients (25.9%) and in the non-ACP side in 12 patients (22.2%). Haller cells were observed in the ACP side in seven patients (12.96%) and in the non-ACP side in ten patients (18.51%). CONCLUSION: Disrupted airflow of the well-developed maxillary sinus cavity due to anatomical variations seems to be an effective factor in the formation of ACP.
