Orbital complications of pediatric rhinosinusitis: A single institution report.

BACKGROUND AND OBJECTIVES: Rhinosinusitis is one of the most common infections of childhood. Rhinosinusitis usually limits itself in the pediatric age group, however orbital and intracranial complications may arise in some of the patients. The purpose of the study was to retrospectively analyse the previous treatments and outcomes in pediatric rhinosinusitis patients with orbital complications. METHODS: The effect and prognosis of medical treatment and endoscopic sinus surgery are reported in this study. Twenty-five pediatric patients diagnosed with complicated rhinosinusitis between January 2008 - February 2016 were included in the study. Orbital complications, examination findings, radiological imaging and blood counts were retrospectively collected from patient files. The duration of hospitalization, source of the infection, complications, previous medical and surgical treatments were also retrospectively assessed. RESULTS: Average age of the patients were 8.84 ± 4.02 years (range: 1-16 years). The mean length of stay in hospital was 6.72 ± 3.28 days. Hospitalization in surgically treated group was higher than primarily medically treated group. However this difference could not reach to a statistically significant level (p > 0.05). Mean hospitalization time was found 5.21 ± 2.51 and 8.43 ± 2.87 days in patients diagnosed with preseptal cellulitis and subperiosteal abscess respectively. Hospitalization in patients with subperiosteal abscess was higher than preseptal cellulitis and a statistically significant difference was detected (p < 0.05). CONCLUSION: Morbidity and mortality of orbital complications which are the most common complications of pediatric rhinosinusitis, could significantly be reduced by using appropriate treatment methods and an early diagnosis. Conservative therapy is an effective method for patients with preseptal cellulitis and most cases of orbital cellulitis in children.

Procalcitonin Levels in Chronic Rhinosinusitis.

OBJECTIVE: The aim of this study was to evaluate and compare procalcitonin levels of patients diagnosed with chronic rhinosinusitis (CRS) with nasal polyposis (CRSwNP) and CRS without nasal polyposis (CRSsNP) along with healthy controls. METHODS: A total of 67 subjects were included. Twenty-two CRSwNP patients were included in group A, 25 CRSsNP patients in group B, and the control group (group C) consisted of 20 healthy subjects. Procalcitonin level was assessed after CRSwNP or CRSsNP diagnosis. Healthy individuals scheduled for septorhinoplasty constituted the control group. Nasal polyposis was graded according to the Meltzer Clinical Scoring System. RESULTS: The mean procalcitonin levels of patients of groups A, B and C were 0.042±0.020 µg/L, 0.031±0.016 µg/L and 0.031±0.010 µg/L, respectively. Mean procalcitonin levels were significantly higher in group A compared to groups B and C (p=0.05 and p=0.032). However, mean procalcitonin levels were not significantly different between group B and group C (p=0.962). Four patients (18%) had grade 1, three had (13.6%) grade 2, eight had (36.4%) grade 3, and seven had (31.8%) grade 4 polyposis. Mean procalcitonin levels for grades 1, 2, 3 and 4 polyposis were 0.045±0.030 µg/L, 0.037±0.006 µg/L, 0.041±0.021 µg/L and 0.043±0.019 µg/L, respectively. No statistical significance was present regarding the mean procalcitonin levels of polyposis grades (p>0.05). CONCLUSION: Procalcitonin, which is an important inflammatory marker especially in sepsis and systemic inflammation, was significantly elevated in CRSwNP patients compared to CRSsNP patients and healthy controls. This may support the presence of chronic mucosal inflammation in CRSwNP patients. However, procalcitonin is an indirect marker of inflammation and further studies with larger patient groups are warranted.

Comparison between Rescue Flap and Double Flap Technique.

Objectives Endoscopic techniques in pituitary surgery lead to inevitable mucosal loss of the sphenoethmoidal recess and posterior nasal septum in the nasal cavity. There is no other comparative study between primary reconstruction of septal perforation and secondary healing in the literature. The aim of this study is to evaluate postoperative patient morbidity with or without posterior septal perforation in endonasal pituitary surgery by comparing two commonly used techniques: rescue and double nasoseptal flaps. Design Prospectively randomized study. Setting Tertiary academic center. Participants Sixty patients underwent endoscopic endonasal pituitary surgery. Main Outcomes and Measures Functional results (breathing) using visual analog scale (VAS), sphenoid sinusitis, presence of synechia, perforation in the posterior septum, and crusting in the sphenoethmoidal recess were assessed. Results Pre- and postoperative mean VAS scores were 71.67 ± 11.47 and 67.67 ± 9.71 mm in the intact septum group and 77.67 ± 14.06 and 62.67 ± 10.48 mm in the posterior septal perforation group. There was a significant difference between pre- and postoperative VAS values in all groups. There was significant worsening in both groups; worsening in VAS values was much higher in the posterior septal perforation group. In the posterior septal perforation group, much more crusting was seen. Conclusions This is the first study to compare the postoperative patient morbidity in endoscopic endonasal pituitary surgery with and without a posterior septal perforation. Reconstruction of the posterior septum along with less mucosal loss yields better postoperative nasal symptom score.

Transcutaneous Suture Tip Plasty: The Technique and Outcomes.

PURPOSE: Radical resections and invasive techniques have been mostly replaced with more conservative techniques. The aim of this study was to assess the objective and the subjective functional and aesthetic outcomes of transcutaneous suture tip plasty. METHODS: A total of 20 patients were included in the study. Patients were treated with transcutaneous suture tip plasty. Functional results were assessed with pre- and postoperative 6-month Sino-Nasal Outcome Test (SNOT-22) and acoustic rhinometry. The pre- and postoperative 6-month mean values of first minimal cross-sectional area (MCA1), second minimal cross-sectional area (MCA2), the distance from the tip of the probe to the first minimal cross-sectional area, the distance from the tip of the probe to the second minimal cross sectional area, nasal volume 1, and nasal volume 2 were measured. Facial analysis was made with the Rhinobase software, designed for facial analysis. RESULTS: The mean pre- and postoperative SNOT-22 scores were 25.55 ± 6.64 and 15.70 ± 8.11, respectively (P < .05). The mean pre- and postoperative nasolabial angles were 82.26º ± 5.69º and 101.47º ± 7.70º, respectively (P < .05). The mean pre- and postoperative nasofrontal angles were 144.30º ± 3.81º and 138.25º ± 3.26º, respectively (P < .05). The mean pre- and postoperative nasal length was 54.22 ± 4.62 mm and 49.95 ± 2.75 mm, respectively (P < .05). The mean pre- and postoperative tip projection was 25.77 ± 3.64 mm and 28.40 ± 2.97 mm, respectively (P < .05). Only postoperative MCA2 values on the right and left side were significantly different from preoperative MCA2 values (P < .05). None of the remaining postoperative acoustic rhinometry scores significantly differed from preoperative scores. Two patients (10%) required revision at around 1 month after surgery due to suture loosening and breakage. CONCLUSIONS: Especially in the era of minimal invasive surgery, transcutaneous suspension tip plasty is promising, with rapid and reliable functional and cosmetic results. Further studies with longer follow-up durations are needed to assess the long-term outcomes of this technique.

The Joint Tip Graft: A Joint Support for Rim, Facet and Infratip Lobule in Rhinoplasty.

BACKGROUND: The authors of this study have developed a novel graft called the 'The Joint Tip Graft' which adds support to the lateral crus, camouflages the tip grafts, supports the facet and adds volume to the nasal tip as a single graft. The aim of this study was to define and introduce the tripod graft. METHODS: Thirty patients who underwent primary rhinoplasty at a tertiary academic center were included. Patients were randomly assigned into two groups according to the grafts used: group 1: Joint tip graft was additionally used, and group 2: Joint tip graft was not used. All patients were photographed by a photographer who is familiar with medical photography. Preoperative and postoperative sixth month photographs were taken for analysis. The brightest point of the infratip lobule and the darkest point of the facets were selected and analyzed with computer software. The luminance ratio of facet to infratip lobule was calculated to overcome light and head position differences. RESULTS: Mean infratip luminance scores were 112.20 ± 5.72 and 109.73 ± 7.13 in groups 1 and 2, respectively (p > 0.05). Mean facet luminance scores were 101.33 ± 4.91 and 89.27 ± 5.11 in groups 1 and 2, respectively (p < 0.05). Facet/infratip luminance ratios were calculated for each group. Mean facet/infratip luminance ratios were 0.90 ± 0.01 and 0.82 ± 0.16 for groups 1 and 2, respectively (p < 0.05). CONCLUSIONS: The joint tip graft is a novel graft that is easy to harvest and apply. It spans both of the alar cartilages, supports the facet area and creates a smooth gradual light shadow transition. Additionally, it acts as a camouflage over the tip grafts.

Cavernous Sinus and Parasellar Region: An Endoscopic Endonasal Anatomic Cadaver Dissection.

The aim of this study was to investigate the neurovascular structures of the cavernous sinus with the endonasal endoscopic transpterygoid approach on fresh human cadavers. Additionally, the course of internal carotid artery (ICA) and relevant anatomy was thoroughly investigated to refine the anatomical landmarks, exposure difficulties, potential complications, and limitations using the endonasal endoscopic technique. This study was carried out at an otolaryngology department of a tertiary medical center between June 2014 and June 2015. The surgical dissection was performed on 10 fresh human cadaver specimens using paranasal sinus and skull base endoscopic instruments. Cavernous sinuses and parasellar area were explored via an endoscopic endonasal transpterygoid approach. Dehiscence was present in 5 (25%) cavernous ICAs. Projection of the cavernous ICA on the whole lateral sphenoid wall was prominent in 6 (%30) sphenoid sinuses. Anterior curve was prominent in 12 (60%) cavernous ICAs, whereas posterior was prominent in 7 (35%). Mean distance between the lateral wall of eustachian tube orifice and petrous ICA was 19.50 ± 1.05 mm (range 18-22 mm). Cranial nerves of the cavernous sinus showed no variation. Control of the ICA is critical during the endonasal endoscopic approach to the cavernous sinus and skull base. The vidian nerve is a reliable and important landmark to the petrous ICA in the transpterygoid approach. Dissection of the eustachian tube and its relation to the ICA has to be kept in mind during nasopharyngeal surgery.

Endoscopic endonasal approach to the vidian nerve and its relation to the surrounding structures: an anatomic cadaver study.

PURPOSE: The aim of this study was to investigate the neurovascular structures and their relevant anatomy with the endonasal endoscopic transpterygoid approach on fresh human cadavers. In addition, the relationship between the vidian nerve, ICA and surrounding structures were investigated METHODS: This study was carried out at an otolaryngology department of a tertiary medical center between June 2014 and June 2015. Ten fresh human cadavers were included in this study. Pterygopalatine fossa was explored via an endoscopic endonasal transpterygoid approach. Same surgical dissection procedures were performed on all cadavers: maxillary antrostomy, anterior and posterior ethmoidectomy, sphenoidotomy, transpterygoid pterygopalatine fossa and vidian canal dissection. RESULTS: Mean distance between the anterior nasal spine and ethmoidal crest was 60.35 ± 1.31 mm (range 59-64 mm). Mean distance between the sphenopalatine foramen and superior border of choana was 18.30 ± 1.38 mm (range 17-22 mm). Mean distance between the vidian canal and sphenopalatine foramen was 6.30 ± 0.47 mm (range 5.5-7 mm). Mean distance between the vidian canal and anterior nasal spine was 64.6 ± 1.71 mm (range 62-67 mm). Foramen rotundum was located superior lateral to the vidian canal in all specimens. Mean distance between foramen rotundum and vidian canal was 9.45 ± 0.60 mm (range 8.5-10.5 mm). Course of the greater palatine nerve was always medial to the descending palatine artery. The mean length of the vidian nerve from the petrous ICA to the point the nerve exits the vidian canal (vidian canal length) was 17.90 ± 1.59 mm (range 16-20 mm). CONCLUSIONS: The distances between the vidian canal and surrounding neurovascular structures would help the skull base surgeon in this narrow and complex area.

Outcome of In Situ Septoplasty and Extracorporeal Subtotal Septal Reconstruction in Crooked Noses: A Randomized Self-Controlled Study.

IMPORTANCE: Severe dorsal deviations in crooked noses are treated by either in situ septoplasty with asymmetric spreader grafts (ISS) or extracorporeal subtotal septal reconstruction (ECS). To our knowledge, except one retrospective study, there is no other that compares the objective and subjective results of these two treatment modalities. OBJECTIVE: The aim of this study was to compare the aesthetic and functional outcomes of ECS and ISS in crooked noses. DESIGN, SETTING AND PARTICIPANTS: This study was carried out on 40 patients (ISS in 20 patients and ECS in 20 patients) who underwent external rhinoplasty surgery due to crooked noses between May 2014 and January 2016. While performing rhinoplasty on the patients, the decision of whether to use the ECS or ISS technique was randomized in a sequential fashion. MAIN OUTCOMES AND MEASURES: Surgical outcomes were assessed and compared using the anthropometric measurement of photographs with Rhinobase software. Subjective assessments of nasal obstruction and aesthetic satisfaction were evaluated with a visual analog scale. RESULTS: There was a significant difference between rhinion deviation angle, supratip deviation angle (SDA) and tip deviation angle pre- and postoperatively in the ECS group, whereas in the ISS group, except SDA, all other postoperative angles were significantly improved from preoperative values (p = 0.218). The nasal tip projection in the ECS and ISS groups was 29.48, 31.5 preoperatively and 29.78, 31.26 postoperatively. The mean postoperative nasal tip projection value (p > 0.005) did not change significantly compared to the preoperative value in both groups. The mean postoperative value of nasolabial (p = 0.226) angle did not change significantly compared to the mean preoperative one in the ECS group. However, in the ISS group, the mean postoperative value of nasolabial (p = 0.001) angle significantly improved compared to the mean preoperative value. There was significant improvement in both groups, while improvements in both functional and aesthetic outcomes were much higher in the extracorporeal group. None of the patients had postoperative nasal obstruction that required revision surgery. One patient underwent revision rhinoplasty due to an irregularity on the nasal dorsum in the ECS group. CONCLUSIONS AND RELEVANCE: This is the first study that compares subjective and objective aesthetic and functional outcomes of crooked nose surgery according to two common septoplasty techniques in a randomized self-controlled fashion. This study was effective in both objectively and subjectively comparing the functional and aesthetic aspect of the patients submitted to two common different techniques of treatment of nasal deviations in crooked nose patients.

Primary Sinonasal Malignant Melanoma: Effect of Clinical and Histopathologic Prognostic Factors on Survival.

BACKGROUND: Mucosal melanoma is a rare malignancy arising from melanocytes of the mucosal surfaces. The pattern and frequency of oncogenic mutations and histopathological biomarkers have a role on distinct tumour behaviour and survival. AIMS: To assess the rate of C-KIT positivity and its effect on survival of surgically treated sinonasal malignant melanoma patients with other histopathological biomarkers and clinical features. STUDY DESIGN: Retrospective cross-sectional study. METHODS: Seventeen sinonasal malignant melanoma patients with a mean age of 65.41 (39-86) years were included. Overall survival and disease-specific survival rates were calculated. The impact of age, gender, stage and extent of the disease, type of surgery, and adjuvant therapies were also taken into consideration. The effect of mitotic index, pigmentation, S100, HMB-45, Melan-A and C-KIT on survival were evaluated. RESULTS: Median tumour size was 20 mm (interquartile range=27.5 mm). Pigmentation was present in 7 (41.2%) cases. Median number of mitoses per millimetre squared was 11 (interquartile range=13). Melan A was positive in 7 (41.2%) patients, ulceration was present in 6 cases (35.3%), and necrosis was present in (47.1%) 8 cases. Six patients (35.3%) were positive for S100, 14 (82.4%) specimens stained positive for HMB-45 and C-KIT (CD117) was positive in 9 cases (52.9%). Three patients (16.7%) developed distant metastasis. Five year overall and disease free survival rates were 61.4% and 43.8%, respectively. CONCLUSION: Although C-KIT positive sinonasal malignant melanoma patients (52.9%) can be candidates for targeted tumour therapies, the studied clinical or histopathological features along with C-KIT seem to have no significant effect on survival in a small group of patients with sinonasal malignant melanoma.

Evaluation of Inferior Turbinate Stroma with Ultrasound Elastography in Allergic Rhinitis Patients.

BACKGROUND: Diagnosis of allergic rhinitis is primarily based on history, physical examination and allergy testing. A technique that noninvasively evaluates the soft tissue changes in the nasal mucosa of allergic rhinitis patients has not been defined. AIMS: To assess nasal mucosal changes and measure the submucosal fibrosis in allergic rhinitis patients with sonoelastography. STUDY DESIGN: Case control study. METHODS: Eighty-eight turbinates of 44 patients were included in the study. There were 23 prick test positive allergic rhinitis patients. The control group constituted 21 patients. The rhinitis quality of life questionnaire and the visual analogue scale were applied to the allergic rhinitis patients. A higher visual analogue scale score indicated more severe allergic rhinitis symptoms. Sonoelastographic measurements were made from the lateral nasal wall. The propagation speed of sound waves was recorded in m/s. The presence of asthma and the type of allergic rhinitis (seasonal or perennial) was noted. RESULTS: Ten patients had seasonal allergic rhinitis and thirteen patients had perennial allergic rhinitis. Six patients (26.1%) had accompanying asthma along with allergic rhinitis. The median visual analogue scale score was 7 (3-9) in allergic rhinitis patients. The median symptom duration was 7 (1-24) months. The median quality of life questionnaire score was 3.39 (1.68-5.43) points. The median sonoelastography scores of allergic rhinitis patients and healthy subjects were 2.38 m/s (0.9-4.47) and 2.42 m/s (1.62-3.50), respectively. Sonoelastographic measurements of seasonal and perennial allergic rhinitis patients did not differ significantly (p<0.05). The presence of asthma did not have a significant impact on the elastography measurements (<0.05). However, regression analysis revealed a significant inverse correlation (coefficients: B=0.005, standard error=0.097, beta 0=0.008) between the visual analogue scale and sonoelastography scores (p>0.05). CONCLUSION: Sonoelastography was not suitable as a diagnostic tool in allergic rhinitis. Reduced sonoelastography scores were measured in more symptomatic patients. Higher visual analogue scale scores could be an indicator of disease severity.

Double nasoseptal flap technique for endonasal pituitary surgery.

Endoscopic endonasal approach has been successfully used for the management of pituitary tumors; however, the loss of septal mucosa especially around sphenoethmoidal recess and posterior nasal septum might be a disadvantage of this technique. The aim of this study is to describe a variation of the endonasal approach, "double nasoseptal flap" technique in endoscopic transsphenoidal pituitary surgery, and to evaluate its outcomes. The technique depends on fully harvested bigger nasoseptal flap on one side and smaller on the other. Thirty patients were included. Functional results were assessed by preoperative and postoperative first month visual analogue scale (VAS), and morphology was evaluated by achieving intact septum from the sphenoid ostium to the columella. Sphenoid sinusitis, the presence of synechia and crusting in the sphenoethmoidal recess was also assessed. Mean VAS was 71 and 67 mm preoperatively and postoperatively, respectively (p > 0.01). There were no septal perforations, synechia, and sphenoid sinusitis postoperatively. Three patients had (10 %) crusts on sphenoethmoidal recess on first month postoperatively. Double nasoseptal flap technique has advantages, such as wider exposure during surgery; prepared flaps could be used if needed, better morphological and functional outcomes postoperatively. The technique is safe without any perforations and minimal crusting.

Acute invasive fungal rhinosinusitis: Survival analysis and the prognostic indicators.

BACKGROUND: Acute invasive fungal rhinosinusitis (AIFR) is a highly mortal, progressive fungal infection of the paranasal sinuses and surrounding structures that is almost always seen in patients who are immunocompromised. Despite the use of newer antifungal treatments and early diagnosis, the prognosis of AIFR does not improve significantly. Due to the higher incidence of patients who are immunocompromised and have more complex disease, AIFR is a growing medical issue in tertiary medical centers. OBJECTIVE: The aim of this study was to present the outcomes and analyze the prognostic indicators of patients with AIFR who underwent surgery. METHODS: Between October 2009 and November 2014, 37 patients who underwent surgery for AIFR at a tertiary care university hospital were included in the study. Overall survival and disease-specific mortality and survival rates were calculated to estimate survival function. The impact of age, sex, underlying disease, extent of AIFR, applied medical treatment, and causative species (mucormycosis, aspergillosis) were also taken into consideration. Also, the effect of a variety of laboratory parameters, such as hemoglobin, leukocyte, neutrophil, lymphocyte, platelet, and C-reactive protein (CRP) levels, to survival were evaluated. RESULTS: The median follow-up time was 58 days (interquartile range = 304). Overall and disease-specific mortality rates were 64.9 and 51.4%, respectively. Fever was the most common symptom (86.5%), along with nasal obstruction and/or fullness (48.6%) and epistaxis (48.6%). Age and sex did not have a significant impact on survival (p > 0.05). Palate involvement was significantly associated with mortality (p < 0.05). According to the results of Cox, regression analysis for disease-specific mortality rate, leukocyte and neutrophil counts as well as CRP levels had a significant effect on survival function (p < 0.05). CONCLUSIONS: Palatal involvement was associated with a higher mortality in our study. Also, leukocyte counts, neutrophile counts, and CRP values had a significant impact on survival function. The reversal of the underlying disease and immunosuppression is as important as the medical and surgical treatment.

Primary thyroid-like papillary adenocarcinoma of the nasal septum: a case report.

Primary thyroid-like papillary adenocarcinomas are extremely rare neoplasms that generally originate in the nasopharynx. We report the case of a 24-year-old woman who was diagnosed with a thyroid-like papillary adenocarcinoma that originated in the nasal septum. The tumor was surgically removed, and the patient showed no evidence of local recurrence during 4 years of follow-up.

Collision tumors of the paranasal region: presentation of two cases.

Collision tumors in the paranasal region are extremely rare with limited literature data. To the best of our knowledge, this is the first report of associations of squamous cell carcinoma-esthesioneuroblastoma and lymphoma-hemangiopericytoma in the paranasal region. Preoperatively, radiological and clinical findings should be evaluated carefully for the diagnosis and two or more biopsy specimens should be taken from different morphological parts of the lesions. Adjuvant therapy should be planned according to two different histologies and special importance should be given to the tumor which indicates the prognosis of the patient. A multidisciplinary approach is required for the management of synchronous malignancies.

Does mannose-binding lectin have a role in adult Turkish patients with nasal polyposis?

OBJECTIVE: Mannose-binding lectin is an important component of innate immunity; it initiates the lectin pathway of complement activation critical for innate immunity. Failure of local innate defenses may result in defective responses that lead to the persistent carriage of microorganisms or ongoing inflammation. This study investigated the role of mannose-binding lectin levels and the frequency of the 6 functional mannose-binding lectin polymorphisms in Turkish individuals with nasal polyposis. STUDY DESIGN: A case-control study. SETTING: University hospital. SUBJECTS AND METHODS: Fifty-one patients with nasal polyposis and 53 healthy controls were enrolled. Serum mannose-binding lectin levels were obtained by enzyme-linked immunosorbent assay (ELISA) using the mannose-binding lectin oligomer ELISA kit. Mannose-binding lectin 2 genotyping was performed by isolating the genomic DNA from leukocytes. RESULTS: Mean mannose-binding lectin levels were 1693.2 and 1887.8 in the patient and control group, respectively. Although mannose-binding lectin levels were lower in the patient group, the difference was not statistically significant (P > .05). No overall association was observed between the mannose-binding lectin genotype and susceptibility to nasal polyposis (95% confidence interval = 0.716-4.389, odds ratio = 1.773). The mutant allele frequencies of the 3 structural polymorphisms did not differ significantly between the nasal polyposis patients and the controls (P = .659). CONCLUSIONS: Mannose-binding lectins are not involved in the pathogenesis of nasal polyposis in adult Turkish patients, but additional research is needed for further comment.

The clinical value of the novel cauterization procedure for the inferior turbinate artery during turbinate surgery.

The objective of the study was to evaluate the efficacy and the safety of the novel cauterization procedure of the inferior turbinate artery, which may be performed with any kind of inferior turbinate procedures in reducing the intra and the post-operative bleeding in partial inferior turbinectomy. A prospective controlled study was conducted in a referral center. Sixty patients (38M, 22F) who underwent partial turbinectomy were included. In 20 patients, partial turbinectomy was performed with the cauterization in one nasal cavity and the other one without it. The remaining 40 patients were divided into two groups which comprised cauterization positive and negative patients and are assessed in terms of post-operative bleeding. The area of the cauterization was 1 cm(2) field which is 1 cm anterior to the posterior attachment of the inferior turbinate on the lateral nasal wall, very close to the inferior turbinate, where the pulsating vessel is most commonly seen. Mean operation time, mean intra-operative blood loss and post-operative bleeding incidence are the main outcome measures. Post-operative bleeding was seen in three patients (15%) in the cauterization negative group. No patient had post-operative bleeding in the cauterization positive group. Mean operation time and mean intra-operative bleeding amount were significantly lower in the cauterization positive side. Cauterization of the inferior turbinate artery on the lateral nasal wall is a safe and effective method which may also be performed with any kind of inferior turbinate procedures to reduce both the operation time and intra and post-operative bleeding.

Blood supply of the inferior turbinate and its clinical applications.

One of the most effective treatments of inferior turbinate (IT) hypertrophy is surgical reduction. Bleeding from the IT branch of the posterior lateral nasal artery (ITB) may interfere with the outcome of IT surgery. The aim of this study is to define the anatomic localization of the ITB and its variations and to investigate its clinical importance. Anatomic relations of the ITB were determined by microdissecting 20 adult, sagittally cross-sectioned head specimens. Branching characteristics of the ITB and its anatomical relations were evaluated. The most consistent two markers to define the ITB on the lateral nasal wall were the posterior attachment of the IT (PAIT) and the posterior attachment of the middle turbinate (PAMT). Mean horizontal distances of the ITB from the PAIT and the PAMT were 7.2 mm ± 2.8 mm (2.5-11.8 mm) and 8.2 mm ± 2.8 mm (4-14.6 mm), respectively. ITB was the only major artery that supplied the IT in 85% of the specimens, and, in 15%, there was more than one artery. ITB was located lateral to the IT in 95% and medial to the IT in 5%. The ITB coursed on the lateral nasal wall, vertically between the middle and ITs and always anterior to the PAIT. All the variations of blood supply to the IT were within a one square centimeter area, ∼1-cm anterior to the PAIT. Successful cauterization of this particular area may be an alternative cauterization site in IT surgery.

Anatomic variations of sphenopalatine artery and minimally invasive surgical cauterization procedure.

BACKGROUND: Sphenopalatine artery (SPA) ligation or cauterization stands to be one of the most common management options of refractory epistaxis. Ramification pattern of SPA as it passes through sphenopalatine foramen (SPF) has not been clearly established. The aim of this study is to investigate situations in which middle meatal approach may fail due to anatomic variations of SPA and to define a minimally invasive surgical cauterization procedure. Anatomic variations of SPA were determined by microdissection of 20 adult sagittally cross-sectioned head specimens. METHODS: Branching characteristics of SPA and its anatomic relations were evaluated and anatomic variations were noted. RESULTS: SPA was generally (80%) forming branches within SPF before entering into the nasal cavity. In 20% of the specimens, SPF was located superior to the horizontal lamella of the middle turbinate, and accessory foramen was present in 10%. In 10% of the cases, the posterior lateral nasal branch was situated as two branches in a deep sulcus in the middle meatus. CONCLUSION: The ramification pattern of SPA can not be fully exposed without resection of the posterior part of the middle turbinate via the middle meatal approach. Two-step procedures are advocated in reducing failure rates. Previously defined two-step procedures are relatively invasive. A less invasive procedure is defined based on the variations of SPA and SPF.

[Anatomic variations of the paranasal sinuses detected by computed tomography and the relationship between variations and sex]. / Paranazal sinüslerin anatomik varyasyonlarinin bilgisayarli tomografi ile degerlendirilmesi ve bunlarin cinsiyetle iliskisi.

OBJECTIVES: In this study, we evaluated anatomic variations detected by computed tomography (CT) of the paranasal sinuses and their relationship with sex. PATIENTS AND METHODS: Computed tomography scans of the paranasal sinuses of 464 patients (206 males, 258 females; mean age 37.5 years; range 4-87 years) were retrospectively analyzed. In cases requiring further investigation, axial and sagittal views were obtained using multiplanar reformatted images. Bone window images were also obtained particularly to evaluate dehiscence variations. Paranasal sinus variations were classified into eight subgroups according to their origins (nasal septum, ethmoid cells, maxillary sinus, uncinate process, frontal and sphenoid sinuses, orbit, and nasal concha). The frequency of variations was compared between male and females. RESULTS: The most common anatomic variation was agger nasi cells (80.4%) followed by pneumatization of the middle concha (37%). The least encountered variations were pneumatization of the inferior turbinate, bony dehiscence of the ethmoidal roof, and duplication of the middle and superior turbinates. The frequency of variations did not differ significantly with respect to gender (p>0.05) except for frontal hypoplasia, which was more often in females (p<0.05). CONCLUSION: Axial and sagittal views using multiplanar reformatted images can be helpful in eliminating artefacts and in identifying variations of the paranasal sinuses. Utilization of soft tissue and bone windows, when necessary, may facilitate evaluation of dehiscence abnormalities.

Laryngeal findings and voice quality in Sjögren's syndrome.

OBJECTIVE: The effect of Sjögren syndrome (SS) on perceptual ratings of the laryngeal findings using the Reflux Finding Score (RFS) and the Reflux Symptom Index (RSI) and the objective voice quality using Jitter (JITT), Pitch Period Perturbation Quotient (PPQ), Shimmer (Shim), Amplitude Perturbation Quotient (APQ) and Noise-to-Harmonic Ratio (NHR) was examined. METHODS: Seventy-seven patients with SS and seventy-seven healthy individuals for the control group were studied. The Reflux Symptom Index (RSI); nine-item outcomes instrument for assessment of symptoms in patients and the Reflux Finding Score (RFS), eight-item laryngoscopic-based scale for evaluation of laryngeal findings in patients were realised. The Multi Dimensional Voice Program (MDVP) was used for capturing and analysis of the voice samples. For comparison of all parameters of patients and control group subjects, the independent sample t-test was used. RESULTS: The difference of RSI and RFS between patients with SS and control subjects was statistically significant. The difference of voice quality parameters between patients with SS and control subjects expect NHR were statistically significant. CONCLUSION: There is a significant association between SS and a variety of laryngeal pathologies. The SS patients with reflux symptoms and voice problems must be examined by an ENT specialist and local laryngeal manifestations of SS can be treated symptomatically.
