RESUMO
OBJECTIVES: Chronic rhinosinusitis (CRS) endotypes have demonstrated clinical value in guiding treatment decisions. Bacterial lysates are immunomodulators that have shown beneficial effects in various respiratory inflammatory diseases. This study aimed to evaluate the effect of postoperative bacterial lysate therapy on different CRS endotypes. METHODS: Patients diagnosed with CRS who underwent endoscopic sinus surgery were recruited. Bacterial lysates were administered postoperatively for 10 days per month for 3 months to the experimental group comprising patients with a history of frequent upper respiratory infections without adverse reactions. The remaining participants were allocated to the control group. The results of the postoperative 3-, 6-, and 12-month assessments, including the modified Lund-Kennedy (mLK) endoscopic and Sinonasal Outcome Test (SNOT) 22 scores, for the groups were compared. The tissue samples obtained from the participants were evaluated to detect the presence of relevant inflammatory mediators. RESULTS: Among the 92 participants, 47 started bacterial lysate therapy 2 weeks after the surgery. The tissue cytokine profiles and clinical parameters, such as the disease severity and blood eosinophil percentage, of the bacterial lysate and control groups were comparable before treatment. The mLK endoscopic and SNOT-22 scores did not differ after 3, 6, and 12 months of follow-up. The subgroup analysis revealed that the bacterial lysate group had significantly lower mLK endoscopic scores than the control group for CRS without nasal polyps, while there was a tendency toward significance for the interleukin (IL)-5 negative group after 6 months. CONCLUSION: Postoperative bacterial lysate therapy has some beneficial effects on the endoscopic findings of patients with CRS without nasal polyps or those who are negative for IL-5.

Objectives: This study aimed to evaluate the characteristics and treatment outcomes of inverted papillomas involving the frontal sinus. Methods: Patients treated for inverted papilloma involving the frontal sinus between 2003 and 2020 were reviewed. Tumors were classified based on their extent (Extent 1: partially encroaching on the frontal sinus; Extent 2: completely filling the frontal sinus; Extent 3: eroding bony borders beyond the frontal sinus) and site of origin (Origin 1: originating outside the frontal sinus and prolapsing into the frontal sinus; Origin 2: originating from the frontal sinus walls medial to the vertical plane of the lamina papyracea; Origin 3: originating from the frontal sinus walls lateral to the vertical plane of the lamina papyracea). Treatment outcomes including tumor recurrence and patency of the frontal recess were analyzed according to tumor characteristics and surgical treatment modalities. Results: A total of 49 surgical cases were analyzed. Extent 1 were the most common type (n = 27), followed by Extent 2 (n = 15), and Extent 3 (n = 7). The most common sites of origin were Origin 1 (n = 23), followed by Origin 2 (n = 15), and Origin 3 (n = 11). Overall, there were nine recurrences (18.4%). Recurrence was not associated with tumor extent, whereas tumor origin, particularly Origin 3 was associated with higher recurrence; 1/23 (4.3%) for Origin 1, 3/15 (20.0%) for Origin 2, and 5/11 (45.5%) for Origin 3 (Log-rank p < .001). Draf III frontal sinusotomy was associated with in the highest patency rate (84.6%) during the follow-up. Conclusion: The recurrence rate of frontal sinus inverted papilloma depends on tumor origin rather than the extent of the tumor. In particular, lesions originating from the frontal sinus lateral to the lamina papyracea recur frequently. Draf III frontal sinusotomy can achieve patent frontal recess allowing active surveillance. Level of Evidence: IV.
RESUMO
PURPOSE: Snoring is the most common symptom of obstructive sleep apnea. Various objective methods of measuring snoring are available, and even if the measurement is performed the same way, communication is difficult because there are no common reference values between the researcher and clinician with regard to intensity and frequency, among other variables. In other words, no consensus regarding objective measurement has been reached. This study aimed to review the literature related to the objective measurement of snoring, such as measurement devices, definitions, and device locations. METHODS: A literature search based on the PubMed, Cochrane, and Embase databases was conducted from the date of inception to April 5, 2023. Twenty-nine articles were included in this study. Articles that mentioned only the equipment used for measurement and did not include individual details were excluded from the study. RESULTS: Three representative methods for measuring snoring emerged. These include (1) a microphone, which measures snoring sound; (2) piezoelectric sensor, which measures snoring vibration; and (3) nasal transducer, which measures airflow. In addition, recent attempts have been made to measure snoring using smartphones and applications. CONCLUSION: Numerous studies have investigated both obstructive sleep apnea and snoring. However, the objective methods of measuring snoring and snoring-related concepts vary across studies. Consensus in the academic and clinical communities on how to measure and define snoring is required.

Immunoglobulin G4-related disease (IgG4-RD) has recently been well recognized and Kuttner tumor is known to be a chronic sclerosing sialadenitis, representing the focal manifestation of IgG4-RD, in the submandibular gland (SMG). This study is to evaluate the immunologic features of IgG4-related Kuttner tumor in the SMG. We retrospectively chose 13 patients who were confirmed as having Kuttner tumor by surgical biopsy between May 2012 and January 2019. The fine-needle aspiration cytology, serum antibody levels (anti-Ro antibodies, anti-La antibodies), IgG serum levels (total IgG and IgG4), and immunohistochemical findings for IgG and IgG4-positive plasma cells were reviewed. The cytologic results found that 7 of the 9 cases were reported as chronic sialoadenitis, and the other 3 as benign lymphoproliferative lesion. The serum levels of autoantibodies, Sjögren-syndrome-related antigen A/Ro-Ab and Sjögren-syndrome-related antigen A/Ro-La, showed all normal values of serum level. The serum level of IgG was increased in only 4 among the cases. However, the IgG4 levels were significantly increased in 11 among the cases. In all the patients who received resection of SMG, immunohistochemical findings showed all positive for IgG4-RD, with elevated numbers of IgG and IgG4-positive plasma cells. The evaluation of IgG4 serum level should be very informative for the diagnosis of this tumor before surgery. Fine-needle aspiration cytology with ultrasound guidance are not conclusive in this study. The immunological study including IgG4 serum level should be required for proper diagnosis and treatment, with clinical features of the Kuttner tumor. The level of evidence was IV.

Although snoring is the most common subjective symptom in obstructive sleep apnea (OSA), an international consensus on the definition of snoring is lacking. This study aimed to define snoring by analyzing correlations between snoring parameters and the apnea hypopnea index (AHI). We retrospectively analyzed the polysomnography data of patients with OSA. A snoring event was defined when airflow pressure was > 200 microbar. We included four snoring parameters. Snoring percentage was defined as the cumulative time of snoring events divided by total sleep time. A snoring episode was defined as the occurrence of ≥ 3 consecutive snoring events, and the snoring episode index was defined as the number of snoring episodes per hour. The average and longest durations of snoring episodes were also investigated. The study enrolled 5035 patients. Their mean AHI was 26.5/h and the mean snoring episode index was 19.2/h. Although the four snoring parameters showed significant correlations with the AHI, the snoring episode index showed the strongest positive correlation with the AHI (r = 0.741, P < 0.001). The snoring episode index may be used as a definition of snoring from the perspective of a highly positive correlation with the AHI.

Pulsatile tinnitus is an uncommon symptom characterized by a perceived sound pulsing like a heartbeat. Here, we report an unusual case of a patient with unilateral pulsatile tinnitus caused by a large, prominent mastoid emissary vein (MEV). A 45-year-old woman presented at our hospital with pulsatile tinnitus. She had persistent tinnitus for 20 years, and her symptoms had worsened in the previous 2 years. She said that she perceived a sound pulsing like a heartbeat. She had some hearing impairment in both the ears for a long time owing to long-term otitis media. The temporal bone computed tomography scan showed a large right jugular bulb, and there was a large MEV canal draining into the right sigmoid sinus. Therefore, we decided to perform a large MEV ligation with the planned right tympanoplasty. On follow-up, the patient's pulsatile tinnitus improved completely. According to reviews, this is the first reported case of surgical ligation of a large MEV as a treatment for pulsatile tinnitus; therefore, we report this case with a brief literature review.

To investigate the potential relationship between septal deviation (SD) and headache using nationwide representative cohort sample data.This study used a nationwide cohort sample from the Korean National Health Insurance Service database. The cohort sample was composed of 1 million patients, which is obtained by propensity score matching from 2002 to 2013. There were 9171 individuals in the SD group and 28243 in the control or no SD group. The Kaplan-Meier survival analysis, the log-rank test, and Cox proportional hazard regression analysis were used to calculate the incidence, survival curve, and hazard ratio of headache for each group.There were no statistically significant differences in sex (Pâ=â.7708), age (Pâ=â.991), residential area (Pâ=â.9626), or socioeconomic status (Pâ=â.9982) between the 2 groups. The survival curve between SD and control or no SD showed a statistically significant difference. The adjusted hazard ratio for headache incidence during the 10-year follow-up period of the SD group was 1.37 (95% CI: 1.31-1.43).This cohort study suggests that SD is associated with headache. Therefore, these findings suggest that septoplasty can be considered as 1 of the treatment option in SD patients with headache.

Fungal balls consist of rounded conglomerates of fungal mycelia, which can form within a preexisting cavity. They are mostly found in the paranasal sinuses in the head and neck regions. Cholesterol granuloma is a fibrotic lesion that develops as a tissue response to a foreign body such as cholesterol crystals or hemosiderin and is often associated with chronic otitis media. We present the unusual case of a 62-year-old male who was treated for chronic otitis media, which was histologically confirmed as a fungal ball and cholesterol granuloma in the middle ear cavity following tympanomastoidectomy. This is the first reported case of synchronous fungal ball and cholesterol granuloma in the middle ear cavity.
RESUMO
OBJECTIVE: The dental implant is an innovative instrument that enables the edentulous patient to chew. Many factors have a bearing on the success of dental implantation. There are also many complications after dental implantation. In this meta-analysis, we investigated which factors increase the risk of postoperative sinusitis and implant failure after dental implant for the first time. DATA SOURCES: Included data were searched through the PubMed, EMBASE, and Cochrane library databases. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and 2 authors (J.S.K., S.H.K.) independently extracted data by multiple observers. REVIEW METHODS: We used a random-effects model considering the variation between and within the included studies. RESULTS: Twenty-seven studies were included in our final meta-analysis. The proportion of postoperative sinusitis, perforation of the sinus membrane, and implant failure was 0.05 (95% confidence interval [CI], 0.04-0.07), 0.17 (95% CI, 0.13-0.22), and 0.05 (95% CI, 0.04-0.07), respectively, using the single proportion test. The only factors that affected postoperative sinusitis were preoperative sinusitis and intraoperative perforation of the Schneiderian membrane ( P < .01 and P < .01, respectively). The only factors that affected dental implant failure were smoking and residual bone height of the maxilla ( P < .05 and P < .01, respectively). CONCLUSIONS: Two factors affect postoperative sinusitis after implant surgery: preoperative sinusitis and Schneiderian membrane rupture. It should also be noted that the factors affecting implant failure are residual bone height and smoking. These findings will have a significant impact on the counseling and treatment policy of patients who receive dental implants.

RATIONALE: Mucormycosis is a rare fungal infection which mainly develops in compromised hosts and the associated mortality rate is high. PATIENT CONCERNS: We report a case of mucormycosis in a 59-year-old woman following routine endoscopic sinus surgery. The patient had a history of diabetes mellitus (DM) and bronchial asthma. DIAGNOSES: On follow-up 4 weeks after the first functional endoscopic sinus surgery (FESS), she complained of a severe headache and was readmitted for a second period. Endoscopic examination revealed bony erosion and a whitish discharge on the left middle turbinate, which was confirmed as mucormycosis by endoscopic biopsy. INTERVENTIONS: Endoscopic debridement of the necrotic tissue and middle turbinectomy were performed and the patient was treated with intravenous amphotericin B for 3 months (3.5âmg/kg/day). OUTCOMES: About 1 month into the second period of hospitalization, left Bell's palsy had occurred. The facial palsy improved naturally after 2 months of hospitalization. One year after endoscopic debridement, follow-up endoscopy showed that there was no residual lesion. CONCLUSION: This is the first report of mucormycosis after routine endoscopic sinus surgery. We did not miss headache symptom after FESS surgery, and diagnosed mucormycosis through early endoscopic biopsy, which played an important role in curing the patient. In addition to the importance of medical therapy such as DM control for patients, emotional support and psychiatric treatment are also important factors as these patients require hospitalization for a long period, 3 months in the case of this patient.
