Evaluation of osteomeatal complex by cone-beam computed tomography in patients with maxillary sinus pathology and nasal septum deviation.

BACKGROUND: This study aimed to determine if there is a relationship between the presence of maxillary sinus pathology, nasal septum deviation and various lengths of the osteomeatal complex. METHODS: A total of 223 CBCT images were included in the study. The lengths of the osteomeatal complex (maxillary sinus ostium width, infundibulum length, maxillary sinus ostium height) were analyzed. The presence of maxillary sinus pathology, nasal septum deviation, age, sex, right-left, septum deviation level, and the relationship between pathology level and all variables were evaluated. RESULTS: The average maxillary sinus ostium width, ostium height and infundibulum length were 3.06 ± 0.70 mm, 30.10 ± 5.43 mm and 8.82 ± 1.86 mm, respectively. Ostium width was significantly higher in the healthy group than in the groups evaluated in the presence of deviation and pathology. A significant difference was found in infundibulum length only between the healthy condition and the condition evaluated in the presence of deviation. No significant difference was observed between the groups in terms of ostium height. In all groups, ostium height and infundibulum length were significantly higher in men than in women. The age group with the highest average ostium height was found in the 35-44 age group (p < 0.001). CONCLUSION: Identifying normal and abnormal conditions in the osteomeatal complex area is important for diagnosing the cause of a patient's complaint, guiding the surgical procedures to be performed, and preventing possible complications that may arise during surgical procedures.

Invasive Eumycotic mycetoma of the nasal septum in a post-dialysis patient: A case report.

BACKGROUND: Mycetoma is a slowly progressive chronic granulomatous disease of the skin, subcutaneous tissue, and underlying or adjacent cartilage or bone. Most commonly involves the foot region. Other parts such as the knee, arm, leg, head, neck, thigh, perineum, chest, abdominal walls, facial bones, mandible, paranasal sinuses, eyelid, vulva, orbit, and scrotum are seldom affected. METHODS: This is a rare presentation of Eumycotic mycetoma involving the nasal septum. Surgical debridement is done under local anesthesia. Histopathological examination of debrided specimen guided in the diagnosis and treatment. RESULTS: Histopathological examination is the one that confirms the diagnosis and rules out the other granulomatous conditions and fungal rhinitis causing septal perforation. CONCLUSIONS: In an immunocompromised state, we know that mucormycosis and zygomycosis are known to cause aggressive complications like orbital invasion and palatal perforation by vascular route. However, other fungal infections also can lead to septal perforations whenever there is lessened resistance by the mucosal barrier due to trauma (nasal intubations).

Tumor glómico del septum nasal / Glomic tumor of the nasal septum

Presentamos el caso clínico de una mujer de 58 años que consulta por episodios de epis-taxis autolimitadas por fosa nasal derecha asociados a hipersensibilidad al manipular dicha fosa nasal. A la exploración se evidenció en el septum nasal una lesión mucosa nodular, de consistencia dura y aspecto violáceo. Se llevó a cabo exéresis de la misma por vía endonasal, con resultado histopatológico de tumor glómico (TG) del septum nasal. El TG es una neoplasia benigna perivascular, derivada de las células musculares lisas presentes en el cuerpo glómico; estructura con función termorreguladora, formada por un shunt entre arteriolas y vénulas, sin presencia de red capilar. Los cuerpos glómicos están presentes, mayoritariamente, en extremidades (lecho ungueal). Los tumores glómicos son, verdaderamente, excepcionales en el área ORL, existiendo sólo una treintena de casos publicados hasta la fecha a nivel nasosinusal. La mayoría de casos se presentan entre la 5ᵃ y 6ᵃ década de la vida y más, frecuentemente, en mujeres. Plantea diagnóstico diferencial, fundamentalmente, con dos entidades: el paraganglioma (con el que no debe ser confundido desde el punto de vista terminológico ni histológico), y con el tumor fibroso solitario (antiguo hemangiopericitoma). El comportamiento es benigno y el tratamiento es la cirugía

We present the clinical case of a 58-year-old woman who consulted for episodes of self-limited epistaxis in the right nostril associated with hypersensitivity to manipulation of this nostril. Examination revealed a nodular mucosal lesion in the nasal septum, with a hard consistency and purplish appearance. The lesion was excised endonasally, with histopatho-logical result of a glomus tumor (GT) of the nasal septum. The GT is a benign perivascular neoplasm, derived from smooth muscle cells present in the glomus body; structure with thermoregulatory function, formed by a shunt between arterioles and venules, without the presence of capillary network. Glomus bodies are mostly present in the extremities (nail bed). Glomus tumors are truly exceptional in the ENT area, with only about thirty cases published to date at the nasosinusal level. Most cases occur between the 5th and 6th decade of life and more frequently in women. It raises differential diagnosis fundamentally with two entities: paraganglioma (with which it should not be confused from the terminological or histological point of view) and with solitary fibrous tumor (former hemangiopericytoma). The behavior is benign and the treatment is surgery.

Outcome of Endoscopic Repair of Nasal Septal Perforation.

INTRODUCTION: The anterior ethmoidal artery (AEA) flap has been demonstrated to be a reliable option for endoscopic repair of symptomatic nasal septal perforations. The purpose of this study is to study the outcome of this technique. METHODS: A retrospective case series of all consecutive patients who underwent repair of nasal septal perforation utilizing the AEA flap among 2 institutions from August 2020 to July of 2022 was conducted. Demographics and comorbidities were collected preoperatively and postoperatively. The main outcome of this study was to identify the risk factors for surgical failure. RESULTS: Forty-one patients were included. Mean perforation size was 2.2 cm (range 0.5-4.5 cm). Mean age was 42.5 years (range 14-65 years), 53.6% were female, 39% were active smokers, mean body-mass-index (BMI) was 31.9 (range 19.1-45.5), 20% with history of CRS and 31.7% had diabetes mellitus (DM). Etiologies of the perforation included idiopathic (n = 12), iatrogenic (n = 13), intranasal drug use (n = 7), trauma (n = 6), and secondary to tumor resection (n = 3). Overall success rate for complete closure was 73.2%. Active smoking, history of intranasal drug use, and DM were significantly associated with surgical failure (72.7%vs 26.7%, P = .007; 36.4%vs 10%, P = .047; and 63.6%vs 20%, P = .008 respectively). CONCLUSION: The endoscopic AEA flap is a reliable technique for closure of nasal septal perforation. It may not work when the etiology is intranasal drug use. Close attention to diabetes and smoking status is also needed.

A Case of Cavernous Hemangioma on the Lateral Wall of the Inferior Nasal Meatus.

Hemangiomas, which originate in the sinonasal area, are not common among the various types of tumors from the head and neck region. Mechanisms for the formation of the tumor are yet to be discovered, and a few factors such as trauma, infection, oncogene, and some hormones are considered to take a role in the occurrence and growth of the tumor. Hemangiomas are classified for their histologic features as cavernous, capillary, and mixed types. There are a few reported cases of cavernous hemangiomas of the maxillary sinus, ethmoid sinus, middle and inferior nasal turbinate, and nasal septum. However, a case of cavernous hemangioma from the inferior nasal meatus, on the lateral wall to be precise, has never been reported. The authors are the first to report a case of a 69-year-old female patient who had cavernous hemangioma which was originated from the lateral wall of the inferior nasal meatus and successfully managed.

Endoscopic Resection of a Massive Pleomorphic Adenoma of the Nasal Septum.

Pleomorphic adenoma is a benign tumor that commonly arises from the major salivary glands, such as the parotid and submandibular glands. However, they rarely originate from the nasal cavity. Herein, we describe the case of a 49-year-old woman who presented with nasal obstruction. Preoperative evaluation revealed a giant pleomorphic adenoma attached to the nasal septum. Transnasal endoscopic removal was successfully performed using a specimen retrieval bag. We performed an endoscopic complete en-bloc resection of a large pleomorphic adenoma in the nasal cavity, using a specimen retrieval bag. There were no complications seen, no local recurrences after 2 years of follow-up, and the patient satisfaction was high. We therefore recommend that this technique of using specimen retrieval bags can be favorably utilized for endoscopic removal of large nasal tumors like pleomorphic adenoma.

Nasal Septal Angiofibroma.

Juvenile nasopharyngeal angiofibroma is a benign vascular tumor seen predominantly in adolescent males in the second decade of life. Extranasopharyngeal angiofibroma includes vascular fibrous masses that occur outside the nasopharynx. The diagnosis of an angiofibroma is based on the clinical presentation and imaging, with biopsies being avoided to avoid excessive bleeding. Computed tomography scan is considered sufficient for the diagnosis of extranasopharyngeal angiofibroma as it clearly delineates and identifies the tumor.

A highly specific recurrent pleomorphic adenoma of the nasal septum.

A 90-year-old woman presented with the sudden onset of visual loss. She previously underwent surgery to treat a right septal pleomorphic adenoma (PA) at 77 years old. She initially presented to our hospital with severe nasal obstruction at 83 years old. A large tumor occupied the bilateral nasal cavities and, thus, surgery was performed using midfacial degloving and an endoscopic endonasal combined approach. A 60×45×43 mm tumor was completely removed; however, a small area of the tumor capsule was damaged. Six years after surgery, PA recurred in the posterior midline portion of the nasal cavity. Imaging examinations revealed a 48×42×45 mm mass, which compressed the bilateral optic canal, thereby causing severe visual loss. The recurrent tumor was endoscopically removed, and vision recovered after surgery. The lack of malignant transformation was pathologically confirmed throughout this period. The present case had several highly specific features: she was very elderly, the tumor was very large, and visual dysfunction was caused by nasal PA. We described surgical procedures in detail and considered the specific findings of the present case. En bloc resection with a sufficient margin was considered to be important in the present case because recurrence may be caused by incomplete excision.

Nasal Septal Angioleiomyoma and Septal Sinus Surgery: A Review of 2 Cases.

Angioleiomyomas are smooth muscle masses originating from blood vessel tunica media. This is a rare tumor, comprising less than 1% of benign sinonasal cavity tumors. Failure to recognize and surgically excise nasal angioleiomyomas can result in lesion recurrence. We present 2 new cases of nasal septum angioleiomyoma at a single institution. Additionally, both cases underwent septal and nasal surgery. Due to the nonspecific clinical and imaging findings, a high index of suspicion is needed to diagnose nasal septum angioleiomyoma, often requiring histopathological verification. Preferred treatment is complete surgical excision. From our experience, concurrent corrective septal and sinus surgery can be completed with tumors less than 1.0 cm in size.

Effects of nasal septum deviation and concha bullosa surgery on the frequency and financial burden of acute rhinosinusitis.

BACKGROUND: Nasal septum deviation/concha bullosa (DNS)/(CB) are known to be predisposing factors in the pathophysiology of acute rhinosinusitis (ARS). However, the effects of surgical treatment of these pathologies on ARS have not been adequately investigated. AIMS: To reveal the effects of the surgical treatment of DNS and CB on the frequency of the ARS, the use of antibiotics (ABs), and the direct cost incurred. METHODS: Medical records of the patients who had undergone successful surgery for DNS/CB and were diagnosed with ARS in the preoperative and postoperative 3-year period were retrospectively analyzed. The average annual number of ARS examinations of the patients, the number of ABs prescribed, and prescription, examination, and total health system costs were compared. RESULTS: Fifty-three patients (33 men (62%) and 20 women (38%)) were included in the study. There was a statistically significant decrease in the mean annual number of examinations for ARS, the number of ABs prescribed, prescription, examination, and total health system costs (p < 0.05) in the postoperative period compared with the preoperative period. CONCLUSIONS: The present study determined that successful surgeries performed in patients with DNS/CB resulted in a significant decrease in the average annual number of examinations performed for ARS, number of AB prescriptions, and prescription, examination, and total health system costs. With these results, it seems beneficial to direct patients to surgery within the framework of the health policies of countries to reduce the frequency and financial burden of ARS in DNS/CB patients.

INTRANASAL PLEOMORPHIC ADENOMA ARISING FROM THE LATERAL NASAL WALL.

Pleomorphic adenoma is very rare in the sinonasal region, with the most common localization on the nasal septum, followed by lateral nasal wall. In the case presented, a 72-year-old woman was complaining of the right sided nasal obstruction without any other symptoms. The symptom started a year before and increased progressively. Anterior rhinoscopy revealed a mucosa-covered, smooth-surfaced, soft, polypoid, pale, grayish-pink in color mass in the right nasal cavity, approximately 2x2 cm in size. Nasal endoscopy showed the mass to have a broad base on the lateral nasal wall. Computerized tomography scan showed a homogeneous, solid soft tissue mass, 25x18x12 mm in size, which was attached to the lateral nasal wall, behind the nasal vestibule, just in front of the inferior turbinate. Endonasal endoscopic complete tumor excision was performed, during which some spillage of the tumor occurred. Histology diagnosis was pleomorphic adenoma of minor salivary glands. The patient was followed up on regular basis and had no tumor recurrence in the 6th postoperative year. Intranasal pleomorphic adenoma arising from the lateral nasal wall in front of the inferior turbinate is extremely rare, so the presented case is probably the first ever published.

Endoscopic Resection of a Rare Chondromyxoid Fibroma From the Nasal Septum.

ABSTRACT: Chondromyxoid fibroma is a rare benign tumor mostly found in the metaphysis of long bones. In rare cases, it develops in unusual locations. We report a case of chondromyxoid fibroma from the nasal septum. Endoscopic surgery was performed with the patient under general anesthesia. A plasma knife was used to ablate the tumor. No recurrence was noted at the 4-year follow-up. The advantages of endoscopic surgery include direct observation, improved visibility and magnification, reduced intraoperative trauma, and fewer postoperative complications. The advantages of the plasma knife include its ability to separate and ablate the tumor simultaneously while effectively reducing bleeding and maintaining the visibility of the surgical field.

Fibroepithelial Polyps Originating from the Posterior Nasal Septum: A Case Report.

Fibroepithelial polyps are benign tumors of mesodermal origin. They rarely occur in the nasal cavity, with only four such cases reported in the relevant English literature. The location was the inferior turbinate in three cases and anterior nasal septum in one case. The etiology has been suggested in other organs; however, it is entirely unknown in the nasal cavity. Pathological findings play an essential role in the diagnosis of fibroepithelial polyps. We report the case of a 76-year-old woman with fibroepithelial polyps originating from the posterior part of the nasal septum. The fibroepithelial polyps were white-yellow lobular masses that differed from a common inflammatory polyp. We made the diagnosis by excluding the other possible tumors based on a pathological examination. This is the first report about fibroepithelial polyps arising from the posterior nasal septum. She had no potential risk factors that might trigger fibroepithelial polyps in the nasal cavity. This case is a valuable example when considering the potential causes (e.g., female hormones and mechanical pressure) of nasal fibroepithelial polyps.

Schwannoma septal, una causa infrecuente de obstrucción nasal / Septal schwannoma, an uncommon cause of nasal obstruction

Resumen Los schwannomas son neoplasias derivadas de las células de Schwann de la cubierta de los nervios periféricos. Su desarrollo en la región nasosinusal es poco frecuente, especialmente a nivel septal. Su diagnóstico diferencial es variado y debe establecerse con otras causas más habituales de masa nasal unilateral. Su tratamiento es quirúrgico. Describimos el caso de un varón de 47 años con una masa nasal derecha intervenida mediante cirugía endoscópica nasosinusal y con diagnóstico anatomopatológico de schwannoma septal.

Abstract Schwannomas are tumors that proceed from Schwann cells in the cover of peripheral nerves. It is uncommon in the sinonasal area, especially in the nasal septum. The differential diagnosis is extensive and requires contemplating other more frequent causes of unilateral nasal mass. The current treatment of septal schwannoma is surgical. We report a 47-year-old male with a right nasal mass operated by endoscopic sinonasal surgery with an anatomopathological diagnosis of a nasal septal schwannoma.

The Effect of Platelet-Rich Fibrin and Hyaluronic Acid on Perforation of Nasal Septum.

BACKGROUND: Conservative approaches and surgical methods have been tried for the treatment of nasal septum perforations (NSPs), but a satisfactory method has not yet been determined. OBJECTIVE: Our study aimed to investigate the effect of platelet-rich fibrin (PRF) and hyaluronic acid (HA) in repairing NSPs, which were experimentally created in rabbit septum. METHODS: A total of 36 white New Zealand rabbits were included in the study. Perforations measuring 0.7 × 0.7 cm were created in their nasal septa. No additional intervention was made to the control group, which was the first group. For the second, third, and fourth groups, respectively, HA, PRF, and HA + PRF were used in the NSP region. Macroscopic and histopathological evaluations were performed after 40 days. RESULTS: In the first group, closure was observed in none of the rabbits' NSPs. In the second group, 6 rabbits (66.7%) had full closure in their NSPs. In the third group, the NSP of 6 rabbits (66.7%) was completely closed. In the fourth group, the NSP of 7 rabbits (77.8%) had full closure. CONCLUSION: Statistically significant closure was achieved with PRF and/or HA in rabbits in which NSP was established. These materials can be used to increase the likelihood of perforations closing.

[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.

[Clinical case - neoplasm of the nasal septum, which turned out to be papillary cancer of the ectopic thyroid gland]. / Klinicheskii sluchai ­ novoobrazovanie peregorodki nosa, okazavsheesya papillyarnym rakom ektopirovannoi shchitovidnoi zhelezy.

In this clinical case, papillary carcinoma was detected in the ectopic area of the thyroid gland in the presence of an unchanged thyroid gland of natural localization. An extremely rare disease is presented and an examination algorithm is proposed that is recommended to exclude unusual pathology in the absence of a response to ongoing conservative treatment.

Preoperative Misdiagnosis of Malignant Mucosal Melanoma of the Nasal Septum by MRI.

Malignant sinonasal mucosal melanoma is a rare and aggressive neoplasm. As it shows nonspecific clinical symptoms, magnetic resonance imaging (MRI) is the most effective diagnostic tool. Before a mass is histopathologically confirmed, MRI is regarded as the optimal differential diagnostic procedure, especially in patients who present with a unilateral sinonasal cavity mass. However, we recently treated a patient who showed atypical MRI findings, resulting in a preoperative misdiagnosis of a vascular tumor. By pathologic examination, the patient was confirmed to have a malignant mucosal melanoma that originated from the nasal septum. This case demonstrates that unilateral nasal cavity masses that present with nonspecific symptoms, such as epistaxis, should be evaluated for possible malignant neoplasms, even if the mass has benign-looking characteristics in preoperative endoscopic findings and MRI images.

A Rare Cause of Respiratory Distress in Newborn: Huge Nasal Chondromesenchymal Hamartoma; Patient Report.

ABSTRACT: Nasal chondromesenchymal hamartoma is a rare benign tumor of the sinonasal tract in pediatrics and only few cases in infantile, early pediatric, and adolescent population have been reported. Nasal chondromesenchymal hamartoma commonly presents as respiratory difficulty, intranasal mass, or facial swelling and typically arises from the nasal septum or vestibule, lest frequently maxillary or ethmoid sinuses, orbit, nasopharynx, and oropharynx. The authors report a case of nasal chondromesench- ymal hamartoma that caused respiratory distress since birth, in a 4- week-old (28 days) infant which was arised from the medial aspect of the middle turbinate, an unexpected localization.

Extranasopharyngeal Angiofibroma of the Natural Ostium of Maxillary Sinus.

ABSTRACT: Extranasopharyngeal angiofibroma which occurs in all head and neck regions is extremely rare. Unlike most angiofibromas which show nasal congestion and recurrent epistaxis as their symptoms, extranasopharyngeal angiofibromas (ENAF) may lead to various symptoms depending on their location. Nasal septum is the most frequent site of origin of ENAF. No study of ENAF originating in natural ostium of maxillary sinus has been reported. We present a case of 27-year-old male who has extranasophar- yngeal angiofibroma arising from the natural ostium of maxillary sinus in an adult patient whose symptom was right sided nasal obstruction. With this study, although uncommon, angiofibroma should be considered as a differential diagnosis in patient with mass lesion in the middle nasal meatus.
