    Abstract: Because dental implantation and sinus augmentation are widely performed in recent years, one of their possible complications, maxillary sinusitis, has become a major concern for both dentists and otolaryngologists. This study evaluates the characteristics of dental implant–related chronic rhinosinusitis (DIrCRS) and the outcome of endoscopic sinus surgery (ESS) for these patients. Methods Eighteen patients diagnosed with DIrCRS from 2007 to 2012 and who were recommended for operation were included. ESS served as the first surgical choice. Dental implants were not routinely removed unless there was severe periimplantitis. All data, including CT and surgical findings, were collected and analyzed. Results All 18 patients had findings of maxillary sinus floor perforation or penetration by dental implants on CT. Fifteen of the 18 patients underwent ESS. Two patients had the dental implants removed before ESS and did not experience recurrence. Four patients had recurrence and the dental implants were removed before revised ESS. They did not experience recurrence again after the revised operation. The other nine patients had their dental implants preserved and did not experience recurrence during follow-up. None of the 15 patients required a Caldwell-Luc operation. Conclusion In patients with DIrCRS, ESS can be used as the first surgical choice with good prognosis and low morbidity. Although most cases of DIrCRS are caused by dental implants penetrating into the maxillary sinus, the dental implants can be preserved unless there is severe periimplantitis or recurrence of sinusitis. Nonetheless, the sinus mucosa above the dental implants must be kept intact during ESS.

    Nasal Nitric Oxide in Relation to Quality-of-life Improvements after Endoscopic Sinus Surgery
    SAGE Publications ; 2015

    Abstract: The level of nasal nitric oxide (nNO) in patients with chronic rhinosinusitis (CRS) has been proven to increase after surgical treatment. The relationship between nNO and treatment outcome has not been documented to date. Objective To evaluate the levels of and changes in nNO after sinus surgery and its effects on quality-of-life improvements for patients with CRS after surgical treatment. Methods By using a clinical cohort study design, we identified patients who were receiving bilateral endoscopic sinus surgery for CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP) with a 1-year follow-up. We assessed the demographics, preoperative prognostic predictors, pre- and postoperative nNO levels, and disease-related quality of life via a questionnaire. Results Sixty-nine patients were enrolled, including 53 with CRSwNP and 16 with CRSsNP. The CRSwNP group had lower initial nNO levels and higher endoscopic and image scores but similar demographics and questionnaire scores. In the patients with CRSwNP, nNO levels recovered and reached a plateau at the third month after surgery. However, nNO levels in the CRSsNP group continued to increase until 6 months after surgery before reaching a steady level. Higher preoperative nNO levels were significantly related to better quality-of-life improvements at 3 months after surgery in both groups. Conclusion The nNO levels in patients with CRS increased and reached a plateau after sinus surgery for both groups. Under similar subjective disease severity, the CRSsNP group had higher preoperative nNO levels and maintained a continuously longer rise before reaching a steady level after surgery. For both CRS groups, a higher initial nNO level brought better quality-of-life improvements and could be provided as a preoperative prognostic indicator.

    Removal of Displaced Dental Implants in the Maxillary Sinus Using Endoscopic Approaches

    Abstract: With the broad indications for dental implantation, complications rates have increased. Dental implant displacement into the maxillary sinus, although rare, can occur during the restoration of maxillary posterior teeth. We performed a 6-year retrospective review and found 3 cases with displaced implants in the maxillary sinus. Detailed information, including surgical indications and dental implant removal methods, is provided. Dental implants can be dislocated to the maxillary sinus perioperatively or postoperatively. Endoscopic sinus surgery can be performed to remove the implant and restore sinus patency. If the implant is displaced to deeper areas (commonly anterior and inferior) of the maxillary sinus, a prelacrimal recess approach can provide a panoramic view of the maxillary sinus and is a good alternative to the Caldwell-Luc operation in terms of mucosal preservation and postoperative complications.

    Serum Aspergillus fumigatus -Specific IgG as a Complementary Biomarker in Differentiating Endotypes of Chronic Rhinosinusitis: A Study on Its Role and Diagnostic Efficacy in Type 2 Inflammation

    Abstract: Aspergillus is one of the most common pathogens causing fungal allergy in the respiratory tract. Serum Aspergillus fumigatus-specific immunoglobulin G (Af-sIgG) levels have been used as a biomarker for the diagnosis and treatment response monitoring in airway allergic diseases such as allergic bronchopulmonary aspergillosis and allergic fungal rhinosinusitis. However, its role in common primary chronic rhinosinusitis (CRS) was unclear. Objective This study aims to evaluate whether serum Af-sIgG level could serve as a biomarker for the disease presentation of primary CRS. Methods We obtained serum Af-sIgG levels from patients diagnosed as bilateral primary CRS refractory to medical treatment and evaluated the correlations between serum Af-sIgG levels and disease severity in patients with type 2 (T2) and non-T2 CRS. Results Patients with T2 CRS exhibited significantly higher serum Af-sIgG levels than non-T2 CRS patients. The cut-off value of serum Af-sIgG in T2 CRS was 20.9 mg/L, with an odds ratio of 3.8 (95% CI 1.17-12.20, P = .026). Furthermore, serum Af-sIgG levels were positively correlated with symptom scores evaluated by the Sino-Nasal Outcome Test-22 (SNOT-22) scores in T2 patients ( P = .009). While stratified by SNOT-22 total scores, patients with severe disease had higher serum Af-sIgG levels only in T2 CRS ( P = .034). In individual domains of SNOT-22 analysis, serum Af-sIgG levels showed a significant correlation with “ear/facial” symptom scores in the T2 group ( P 〈 .001). Conclusions Serum Af-sIgG levels may serve as a supplementary objective biomarker that correlates with identification and subjective measurements of T2 CRS, and may be associated with symptoms arising from Eustachian tube dysfunction.
