Platelet-Rich Plasma Injection in Patients with Atrophic Rhinitis.

OBJECTIVE: To investigate the effect of platelet-rich plasma (PRP) injection in patients with atrophic rhinitis. METHODS: Prepared PRP was injected into the inferior turbinate bilaterally, and nasal bacterial cultures were conducted. Improvement of symptoms was assessed with the Nasal Obstruction Symptom Evaluation (NOSE) and the Sino-Nasal Outcome Test-22 (SNOT-22). Nasal mucociliary clearance was assessed using the saccharin transit time (STT). RESULTS: In the PRP-injected group (group A), NOSE (throughout the study) and SNOT-22 (1 month after injection) scores were significantly decreased during the study. However, the saline spray group (group B) showed no significant nasal symptom improvement during the study period. In group A, the STT was improved until 3 months after the injection. In contrast, group B showed STT improvement after 2 months that was maintained throughout the study. CONCLUSION: PRP injections can improve nasal symptoms and nasal mucociliary function in patients with atrophic rhinitis.

Historia del manejo de rinitis atrófica / The history of the treatment of atrophic rhinitis

La rinitis atrófica es una enfermedad crónica progresiva caracterizada por dilatación anormal de las cavidades nasales con atrofia de la mucosa, submucosa y cornetes nasales subyacentes. Los factores etiopatogénicos aún son desconocidos. Su presentación clínica consiste en congestión nasal paradójica asociado a secreciones viscosas, con presencia de costras secas de mal olor. La higiene nasal con irrigación de alto volumen y baja presión es el estándar de tratamiento médico. El tratamiento quirúrgico busca reducir el tamaño de las cavidades nasales y promover la regeneración de la mucosa nasal así como también su vascularización y lubricación. A lo largo de la historia se han descrito múltiples procedimientos quirúrgicos que han buscado estrechar la cavidad nasal para permitir el paso de aire de forma más fisiológica. Por otra parte, se han propuesto intervenciones radicales como el cierre de las fosas nasales para disminuir los síntomas y mejorar la calidad de vida. En este artículo se resumen los principales manejos y procedimientos propuestos junto con sus resultados y conclusiones. Si bien la mayoría de las técnicas descritas ya no se utilizan en la actualidad, es importante conocerlas ya que aún existen pacientes que fueron sometidos a ellas pudiendo presentar complicaciones y/o efectos adversos.

Atrophic rhinitis is a chronic progressive disease characterized by abnormal dilatation of the nasal cavities with atrophy of the mucosa, nasal submucosa and underlying nasal turbinates. The etiopathogenic factors are still unknown. Its clinical presentation consists of paradoxical nasal congestion associated with viscous secretions, usually with the presence of dry, bad-smelling crusts. Nasal hygiene with high pressure irrigation remains the standard of medical treatment. Surgical treatment seeks to reduce the size of nasal cavities and promote regeneration of nasal mucosa as well as its vascularization and lubrication. Throughout history, multiple surgical procedures have been described that have sought the narrowing of the nasal cavity to allow the passage of air more physiologically. On the other hand, radical interventions have been proposed such as the closure of the nostrils to reduce symptoms and improve quality. This article summarizes the main proposed procedures along with their results and conclusions. Although most of the techniques described are no longer used today, it is important to know them since there are still patients who were subjected to them and may present complications and / or adverse effects.

Topical Mitomycin-C can help as an adjunct to alkaline nasal wash and rifampicin in primary atrophic rhinitis.

PURPOSE: Primary atrophic rhinitis (PAR) is a well-known old disease characterized by a roomy nose and extensive crustations. This study was designed to investigate the effect of topical Mitomycin-C as an adjunct to medical treatment with respect to objective and subjective improvement in patients treated with PAR. MATERIAL AND METHODS: This prospective randomized controlled study was conducted in a tertiary referral hospital in January 2016 and March 2018. Fifty adult patients aged 18 to 45 with PAR were randomly divided into 2 groups. STUDY GROUP: treatment with Mitomycin-C dissolved in an alkaline wash plus rifampicin and control group: only treated with rifampicin and alkaline nasal wash. Subjective scores for the following symptoms: After 12 weeks of treatment, foul smell, anosmia, crusting, epistaxis, and nasal blockade, an objective score of crusting, the status of nasal mucosa, nature of the secretions and condition of nasal cavity were compared between the two groups. RESULTS: The degree of crustations (P < 0.0001) and the severity of epistaxis (P < 0.0001) were significantly improved in patients treated with Mitomycin-C dissolved in an alkaline wash (i.e. the study group), and the secretions returned significantly to normal (P < 0.0001). Both groups had significant improvements in both subjective and objective parameters of the assessment. CONCLUSIONS: In patients with primary atrophic rhinitis, the use of Mitomycin-C dissolved in an alkaline nasal wash as an adjunct to oral rifampicin can produce a beneficial result than rifampicin and alkaline nasal wash alone.

Is submucosal fat injection effective in atrophic rhinitis? An experimental animal study.

Atrophic rhinitis (AR) is a disease characterized by the extensive dilatation of the nasal cavity and atrophy of the mucosa, submucosa and bone tissue. Its etiological factors are unknown. There is not a satisfying treatment yet and the treatment of the functional impairment in the atrophic cells is still subject to investigation. The objective of this study is to determine at the histopathological level the possible effects of the submucosal fat injection in an experimental model of AR. 12 albino Wistar-Hannover male rats were included in the study. AR was induced with the Pasteurella multocida toxin, which was diluted with saline. As one of the rats died during the study, it was excluded from the evaluation. The right nasal cavities of all rats (11 nasal cavities) were defined as the control group (Group 1). Fat tissue obtained from the abdominal area was injected in the seven left nasal cavities (Group 2). All injections, which were done to the abdominal regions were also done in the left nasal cavities of the remaining four rats, which constituted the sham group (Group 3). After 14 days, all rats were decapitated and the squamous metaplasia and keratinization in the superficial epithelium, degeneration, vacuolar changes in the basal layer, congestion, inflammatory infiltration, vascular proliferation and glandular atrophy in the submucosa are histopathologically classified. The results were analyzed with statistical methods. Although glandular atrophy was significantly regressed in the fat injection group (Group 2) compared to other groups (p < 0.05), the remaining parameters did not show any significant difference among these three groups. The histopathological effect of the fat injection was modest. We concluded that fat injection treatment has no or at the most a very limited effect in the treatment of atrophic rhinitis.

Analyses and treatments of postoperative nasal complications after endonasal transsphenoidal resection of pituitary neoplasms.

In this study, we analyze and discuss the treatments of postoperative nasal complications after endonasal transsphenoidal resection of pituitary neoplasms (PNs). We performed 129 endonasal transsphenoidal resections of PNs and analyzed and treated cases with nasal complications. After endonasal transsphenoidal resection of PNs, there were 26 cases of postoperative nasal complications (20.1%), including nasal hemorrhage (4.8%), cerebrospinal fluid rhinorrhea (6.9%), sphenoid sinusitis (2.3%), atrophic rhinitis (1.6%), olfactory disorder (1.6%), perforation of nasal septum (0.8%), and nasal adhesion (2.3%). All patients clinically recovered after therapy, which included treatment of the cavity through nasal endoscopy, intranasal corticosteroids, and nasal irrigation. We propose that regular nasal endoscopic review, specific nasal medications, and regular nasal irrigation can effectively clear nasal mucosal hyperemia-induced edema and nasal/nasoantral secretions, as well as promote regeneration of nasal mucosa, prevent nasal adhesion, maintain the sinus cavity drainage, and accelerate the recovery of the physiological function of the paranasal sinus. Timely treatment of patients with nasal complications after endonasal transsphenoidal resections of PNs could greatly relieve the clinical symptoms. Nasal cleaning is very beneficial to patients after surgery recovery.

Platelet-rich plasma in otolaryngology.

BACKGROUND: Platelet-rich plasma is a novel material that is being used more frequently in many surgical specialties. METHODS: A literature review on the current and potential uses of platelet-rich plasma in otolaryngology was performed. RESULTS: There is limited evidence on the use of platelet-rich plasma in otolaryngology compared with other specialties: only 11 studies on various subspecialties (otology, rhinology and laryngology) were included in the final review. CONCLUSION: Based on the limited number of studies, we cannot draw safe conclusions about the value of platelet-rich plasma in otolaryngology. Nevertheless, the available literature suggests that platelet-rich plasma holds promise for future research and may have a number of clinical applications.

Rinitis atrófica / Atrophic rhinitis

La rinitis atrófica es una enfermedad crónica y progresiva de etiología desconocida. Se caracteriza por atrofia de la mucosa nasal y hueso subyacente, dilatación anormal de las cavidades nasales, obstrucción nasal paradójica, y formación de secreciones viscosas y costras secas; produciendo fetidez. Sus manifestaciones clínicas más frecuentes son obstrucción nasal, secreción purulenta, costras nasales y mal olor nasal. Se ha separado en dos entidades: primaria y secundaria. El tratamiento es principalmente conservador, y se han propuesto diversas terapias farmacológicas y quirúrgicas. La rinitis atrófica unilateral es una condición infrecuente, con escasos reportes en la literatura científica. Se puede asociar a la desviación septal, por lo que su corrección quirúrgica es una alternativa terapéutica disponible.

Atrophic rhinitis is a chronic disease of unknown etiology. This condition is characterized by progressive nasal mucosal and underlyng bone atrophy, abnormal widening of the nasal cavities, paradoxical nasal congestion and formation of viscid secretions and dried crusts, leading to a characteristic fetor (ozaena). The main clinical manifestations include nasal obstruction, purulent discharge, daily nasal crusting, nasal dryness and foul smell. It has been divided into two separate entities; primary and secondary. Treatment is mostly conservative, although pharmacological and surgical therapies have been proposed. Unilateral atrophic rhinitis is an uncommon condition, with few reports in the scientific literature. It is associated with septum deviation, so surgical correction is one of the therapeutic options available.

Atrophic rhinitis.

A case of atrophic rhinitis complicated by nasal septum perforation is presented, followed by a discussion of the clinical characteristics, pathophysiology, diagnosis, and management of this disease process. Clinical pearls and pitfalls are emphasized for the use of the practicing allergist and fellow in-training. The diagnosis of atrophic rhinitis is guided by a careful clinical history and evaluation to exclude other possible etiologies for the patient's symptoms and physical findings. Because atrophic rhinitis is a poorly understood process, it is surrounded by considerable contention in the literature and its management is not well defined. Atrophic rhinitis often carries significant morbidity and is best addressed by a multidisciplinary approach.

Chronic rhinosinusitis in ex-lepromatous leprosy patients with atrophic rhinitis.

AIM: Rhino-sinus mucosal involvement is well documented in untreated lepromatous leprosy, but less understood in ex-leprosy patients (i.e. leprosy patients who have been treated and cured) with atrophic rhinitis. MATERIALS AND METHODS: Rhino-sinus abnormalities were investigated in 13 ex-lepromatous leprosy patients with atrophic rhinitis, using interviews enquiring about sinonasal symptoms, nasal endoscopy, nasal swab culture and computed tomography. Endoscopic sinus surgery had been performed in three patients. The clinical course, computed tomography findings and nasal biopsy results of these three patients were evaluated. RESULTS: All patients had turbinate atrophy and 6 of the 13 (46.2 per cent) had septal perforation. Paranasal sinus involvement was noted in 9 of 12 examined patients (75 per cent). The most commonly affected sinus was the maxillary sinus (in 8 of 12; 66.7 per cent). All three patients treated by endoscopic sinus surgery experienced relapse and required further surgery. Maxillary sinus irrigation was effective for reduction of persistent symptoms such as postnasal discharge and crusts. CONCLUSION: Ex-lepromatous leprosy patients with atrophic rhinitis had various rhino-sinus abnormalities and persistent symptoms. These patients had chronic rhinosinusitis because of underlying atrophic rhinitis. These patients required repeated otolaryngological observations together with combined surgery and conservative treatment.

Interventions for atrophic rhinitis.

BACKGROUND: Atrophic rhinitis is a chronic nasal pathology characterised by the formation of thick dry crusts in a roomy nasal cavity, which has resulted from progressive atrophy of the nasal mucosa and underlying bone. The common symptoms may include foetor, ozaena, crusting/nasal obstruction, epistaxis, anosmia/cacosmia and secondary infection with maggot infestation. Its prevalence varies in different regions of the world and it is common in tropical countries. The condition is predominantly seen in young and middle-aged adults, especially females, with a racial preference amongst Asians, Hispanics and African-Americans. A wide variety of treatment modalities have been described in the literature, however the mainstay of treatment is conservative (for example, nasal irrigation and douches; nose drops (e.g. glucose-glycerine, liquid paraffin); antibiotics and antimicrobials; vasodilators and prostheses). Surgical treatment aims to decrease the size of the nasal cavities, promote regeneration of normal mucosa, increase lubrication of dry nasal mucosa and improve the vascularity of the nasal cavities. OBJECTIVES: To assess the effectiveness of interventions for atrophic rhinitis. SEARCH METHODS: We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the search was 28 March 2011. SELECTION CRITERIA: Randomised controlled trials (RCTs) studying any treatment or combination of treatments in patients with atrophic rhinitis. We excluded studies with follow-up of less than five months following treatment/intervention. DATA COLLECTION AND ANALYSIS: Three review authors abstracted and assessed studies. We tabulated and then compared the responses of the review authors separately for the individual studies. MAIN RESULTS: No studies met the inclusion criteria for the review. We identified one RCT comparing oral rifampicin plus nasal wash versus nasal submucosal placentrex injection plus nasal wash versus a control group (nasal wash) but had to exclude this study due to inadequate length of follow-up. A further RCT comparing Young's operation with nasal lubrication for primary atropic rhinitis is underway. AUTHORS' CONCLUSIONS: There is no evidence from randomised controlled trials concerning the long-term benefits or risks of different treatment modalities for atrophic rhinitis. Further high-quality research into this chronic disease, with a longer follow-up period, is therefore required to establish this conclusively. 

A new technique for nasal stent fabrication for atrophic rhinitis: a clinical report.

Atrophic rhinitis is a chronic nasal disease characterized by progressive atrophy of the nasal mucosa accompanied by the formation of foul-smelling thick, dry crusts in the nasal cavities. Mild conditions of atrophic rhinitis can be treated by nasal irrigations and prescription of intravenous or topical aminoglycosides. In severe conditions, surgery can close the airways. The problem can also be managed by prosthodontic measures which include the fabrication of a poly methyl methacrylate acrylic resin nasal stents. This article describes a new procedure for fabricating a clear acrylic nasal stent with an alternative laboratory technique using small cylinders of soft putty as spacers for maintaining a 3-mm restricted nasal airway during processing.

Atrophic rhinosinusitis: progress toward explanation of an unsolved medical mystery.

PURPOSE OF REVIEW: Atrophic rhinosinusitis is a chronic condition associated with considerable morbidity and decreased quality of life. This review describes progress in the characterization of primary and secondary atrophic rhinosinusitis and the development of diagnostic criteria for both syndromes. RECENT FINDINGS: Primary atrophic rhinitis usually develops as a consequence of an acute febrile illness in members of lower socioeconomic groups in developing areas of the world. The clinical setting and presence of culturable Klebsialla ozenae in the purulent, foul-smelling, nasal discharge of these patients forms the basis for diagnosis. An animal model for the disease exists in swine in which case an effective vaccine has been developed. Secondary atrophic rhinosinusitis is a condition that follows destruction of the nasal mucosa by any of a number of inflammatory processes including inflammatory diseases nasal/sinus surgery, and antiangiogenic therapy. Diagnostic criteria include patient reported recurrent epistaxis or episodic anosmia; or physician documented nasal purulence, nasal crusting, chronic inflammatory disease involving the upper airway (e.g. sarcoidosis, Wegener's granulomatosis, etc.) or two or more sinus surgeries. Patients with two more of these have secondary atrophic rhinitis with a sensitivity of 0.95 and a specificity of 0.77. SUMMARY: Atrophic rhinosinusitis results from destruction of the normal respiratory epithelium and transition to a nonciliated squamous epithelium, loss of mucociliary clearance, accumulation of stagnant mucous. That milieu facilitates acute and chronic infection (wet phase), and eventual sclerosis with epistaxis and chronic bloody crusts (dry phase).

Rhinitis sicca, dry nose and atrophic rhinitis: a review of the literature.

Despite the fact that many people suffer from it, an unequivocal definition of dry nose (DN) is not available. Symptoms range from the purely subjective sensation of a rather dry nose to visible crusting of the (inner) nose (nasal mucosa), and a wide range of combinations are met with. Relevant diseases are termed rhinitis sicca anterior, primary and secondary rhinitis atrophicans, rhinitis atrophicans with foetor (ozena), and empty nose syndrome. The diagnosis is based mainly on the patient's history, inspection of the external and inner nose, endoscopy of the nasal cavity (and paranasal sinuses) and the nasopharynx, with CT, allergy testing and microbiological swabs being performed where indicated. Treatment consists in the elimination of predisposing factors, moistening, removal of crusts, avoidance of injurious factors, care of the mucosa, treatment of infections and where applicable, correction of an over-large air space. Since the uncritical resection of the nasal turbinates is a significant and frequent factor in the genesis of dry nose, secondary RA and ENS, the inferior and middle turbinate should not be resected without adequate justification, and the simultaneous removal of both should not be done other than for a malignant condition. In this paper, we review both the aetiology and clinical presentation of the conditions associated with the symptom dry nose, and its conservative and surgical management.

Rinitis atrófica como causa del síndrome de nariz vacía: reporte de caso / Atrophic rhinitis as cause of the empty nose syndrome: case report

La rinitis atrófica es una de las causas del Síndrome de nariz vacía, la cual está relacionada con colonización por gérmenes, inflamación crónica y posterior atrofia progresiva de la mucosa nasal. Típicamente produce síntomas obstructivos nasales, rinorrea y costras fétidas. Se presenta el caso en imágenes endoscópicas, tomográficas y de cultivo en una paciente femenina en la cual por sus comorbilidades el manejo fue exclusivamente médico.

Atrophic rhinitis is one of the causes of the empty nose syndrome that is related to colonization by germs, chronic inflammation and subsequent progressive atrophy of the nasal mucosa. Typically produces nasal obstructive symptoms, runny nose and fetid crusts. Endoscopy, tomography and culture images of a female patient is presented in which by her co-morbidities associated the treatment was medical exclusively.

The diagnosis and management of empty nose syndrome.

Empty nose syndrome (ENS) is a poorly understood and rare iatrogenic disorder resulting from the destruction of normal nasal tissue. In severe forms, it can be debilitating. In this article, the authors elucidate the distinction between ENS and atrophic rhinitis, and provide a systematic approach to the diagnosis and management of ENS. They urge a judicious and cautious approach to turbinate resection, to help better prevent this sequela of nasal surgery. They state that patients with ENS can be rehabilitated and their quality of life substantially improved with nasal augmentation as a means to help restore nasal anatomy toward the premorbid state.

Do chronic changes in nasal airflow have any physiological or pathological effect on the nose and paranasal sinuses? A systematic review.

.A reduction in nasal airflow associated with anatomical defects of the nose such as nasal septal deviation has been proposed to cause nasal pathology. . The majority of animal experiments where one nasal passage is surgically closed over several months report only minor changes in the histology of the nasal epithelium and no rhinitis or sinusitis. .Complete abolition of nasal airflow associated with laryngectomy or the treatment of atrophic rhinitis is not associated with the development of rhinitis or sinusitis. . Radiological studies have shown a lack of association between the degree of nasal septal deviation and evidence of rhinosinusitis. .Such studies provide evidence that reduced nasal airflow causes no significant nasal disease. . There is no convincing evidence that a reduction in nasal airflow is a causative factor for rhinitis or sinusitis.

The aetiology and management of atrophic rhinitis.

Atrophic rhinitis is a chronic, debilitating and recalcitrant disease of the nasal cavities that is prevalent in several parts of the world. It has unique epidemiological features and clinical characteristics. Clinicians and researchers for decades have tried to postulate theories for the aetiology of the primary form of the disease. Management of the disease has seen several medical therapeutic regimens including alternative forms of medicine. Surgical options for the condition are also not completely satisfactory with a number of failures and recurrences. The authors provide here a comprehensive review of the existing literature as regards the aetiology and management of this refractory condition.
