Nasal Dermoid Cyst with Sinus Tract Intranasal Bone: A Case Report

Dermoid cysts are benign tumors originating from germ cells, which can form in various locations, including the nasal area in rare cases. They are of unknown exact etiology, but it is suggested that it is due to abnormal tissue migration during early embryonic development. Nasal dermoid cysts albeit rare, can present in various forms such as sinuses, fistulas, or intracranially extending tracts. They can be asymptomatic and incidentally discovered or present with a visible external mass or sinus that is either painful, infected or cosmetically concerning. If nasal dermoid cysts with an intra-nasal bone sinus tract are left untreated, they can lead to life-threatening complications. This report describes the case of a 6-year-old girl with a nasal dermoid cyst connected to a superficial punctum by an intra-nasal tract. She had undergone surgical excision of a nasal swelling previously diagnosed as a dermoid cyst. One year later, she returned to our clinic with a recurrence of the nasal swelling. Imaging tests revealed a nasal dermoid cyst with a tract extending to the nasal tip, without intracranial expansion. The cyst, along with the entire tract, was successfully removed surgically, and the postoperative follow-up indicated no complications. Histopathology confirmed the diagnosis of a dermoid cyst. This case underscores the significance of considering the dermoid tract in nasal cyst cases and the necessity of its complete removal to prevent recurrence.

Sinogenic Subdural Empyema in a Ten-Year-Old Boy with Sickle Cell Anemia

Objective: Sinogenic subdural empyema remains a neurosurgical emergency, even in the antibiotic era. Sickle cell disease is one of the most frequent hereditary diseases, with an incidence of around 4 in 1000 newborns, which necessitates special considerations before a neurosurgical intervention. Case Description: The case of a 10-year-old boy with sickle cell disease type HbSC is reported, who presented with meningitis about ten days after a nasal sinusitis. CT and MRI showed subdural empyema and immediate intravenous antibiotic treatment was started. The patient received partial exchange transfusion. Craniotomy allowed evacuation of empyema and repairment of a frontobasal dural defect. Endoscopic evacuation of the paranasal sinuses was done in the same anesthesia. After initial good recovery, the patient developed right sided paresis with epileptic seizures a few days later. CT scan revealed three distant empyema recurrencies which were evacuated in a second neurosurgical intervention. The child recovered without neurologic deficit, and control MRI examinations three and twelve months after surgery found frontal and parietal dural thickening as sequelae. Conclusion: Urgent neurosurgical interventions in the presence of sickle cell anemia require special anesthesiologic preparations. An immediate, multidisciplinary approach can lead to a good outcome in these life-threatening situations.

Expression of COX-2 and transcription factor CCAAT enhancer binding proteinβin refractory sinusitis with nasal polyps and its significance

Objective To study the expression and significance of COX-2 and C/EBP-βin refractory sinusitis with nasal polyps,and to explore the relationship between them and the recurrence of sinusitis with nasal polyps.Methods The protein expression of COX-2 and C/EBP-βin 20 cases of refractory sinusitis with nasal polyps,20 cases of sinusitis with nasal polyps and 20 cases of normal nasal mucosa were detected by western blot,and the relationship between the two was compared.Results The expression levels of COX-2 and C/EBP-βin refractory sinusitis with nasal polyps were significantly different from those in refractory sinusitis with nasal polyps(P<0.05);The expression levels of COX-2 and C/EBP-βin sinusitis tissues with nasal polyps were significantly different from those in normal nasal mucosa tissues(P<0.05);The expression levels of COX-2 and C/EBP-βin each group were significantly correlated(P<0.05).Conclusions The high expression of COX-2 and C/EBP-βmay be closely related to postoperative recurrence of sinusitis patients with nasal polyps.Both may be used as objective indicators to judge the postoperative follow-up and recurrence tendency of patients with sinusitis with nasal polyps..

Patterns and incidence of sinonasal malignancy with orbital invasion

Background Sinonasal malignancy with orbital invasion is rare. The objective of the current study was to evaluate the clinical and pathological features, treatment outcomes and survival rates for these malignancies. Methods Ninety-three patients who were treated between 1997 and 2007 were retrospectively reviewed. Age, life style, symptoms, location of lesions, previous occurrences, histological subtypes, and treatment modalities were analyzed. Results Ninety-three patients were evaluated, including 51 men and 42 women： the gender ratio was 1.2 men to 1.0 women. The median age was 40.5 years old. The nasal cavity （34.4%）, the maxillary sinus （29.0%） and the ethmoid sinus （19.4%） were the most common primary malignant tumor sites. Almost half of the patients, 44.1% had squamous cell carcinoma, 13.9% had neuroectodermal carcinoma, 11.7% had rhabdomyosarcoma, 9% had adenocarcinoma and salivary gland-type carcinoma, and 11% had other malignancy. The majority of patients presented with T3/T4 （99%）, N0 （93.1%）, M0 （98%） disease. The distant metastasis rate was 20.9%. The overall survival and disease-free survival rates were 68.1% and 40.9% at three years, respectively. When the overall survival rate was computed according to the epicenter of the original malignant tumor, patients with nasal cavity malignancy and maxillary sinus had the best survival, and patients with ethmoid sinus malignancy had the worse survival （P=0.03）. According to their pathology classification, patients with rhabdomyosarcoma had worse overall survival than those with squamous cell carcinoma, or neuroendocrine carcinoma （P 〈0.001）. Squamous cell carcinoma and rhabdomyosarcoma invaded the orbit more often and malignancy of the nasal cavity invaded the orbit more than malignancy of the nasal sinus. Conclusions For nasal orbital tumors early diagnosis is crucial. Orbital exenteration and postoperative rehabilitation should be carefully considered. The current data suggest that surgical resection with postoperative radiation therapy may offer durable local control.

Systematic review of outcomes for endoscopic sinus surgery and subsequent aspirin desensitization in aspirin-exacerbated respiratory disease

Objective:To review and evaluate outcomes of patients with aspirin-exacerbated respiratory disease(AERD)following endoscopic sinus surgery and subsequent aspirin desensitization.Methods:Electronic searches of OVID MEDLINE(1948 to September 10,2019),EMBASE(1980 to September 10,2019),and PubMed were performed on September 10,2019.A systematic review of the literature was performed using the 2009 PRISMA guidelines.Studies with both preoperative and postoperative data for patients with AERD who underwent sinus surgery and aspirin desensitization were considered appropriate for inclusion.Publications were written in English and included patients aged 18 years or older.Results:Six studies met inclusion criteria for this systematic review.The primary outcome measure was change in symptom profile measured by patient-reported quality of life scores.The results demonstrate statistically significant improvement in symptoms following endoscopic sinus surgery,with sustained improvement following aspirin desensitization.Revision surgery rates were significantly lower in patients maintained on aspirin therapy.Conclusion:This review suggests that surgery followed by aspirin desensitization results in improvement in both subjective and objective outcome measures.The adjunctive use of aspirin desensitization allows for long-term stability in symptom scores.Recurrence of polyps and worsening symptoms requiring revision surgery occurs when aspirin maintenance therapy is inter-rupted.
