A multicenter survey on the effectiveness of nasal irrigation devices in rhinosinusitis patients.

BACKGROUND: Nasal irrigation is widely used as an adjunctive treatment for rhinosinusitis. However, there is little information available regarding the efficacy of the devices used in this procedure. The objective of this study was thus to evaluate the effectiveness of nasal irrigation devices based on the experiences of patients with rhinosinusitis. METHODS: We conducted a multicenter survey study between November 2017 and December 2019. The questionnaire was developed based on the available literature and expert opinion and submitted to the otolaryngology residents and staff of each center as well as those in their networks. RESULTS: Four hundred eighteen patients were enrolled in this study: 76 with acute viral rhinosinusitis (18%), 53 with acute bacterial rhinosinusitis (13%), 156 with chronic rhinosinusitis without nasal polyps (37%), and 133 with chronic rhinosinusitis with nasal polyps (32%). We found that high-volume devices were most effective in helping to clear secretion in patients with acute viral rhinosinusitis, chronic rhinosinusitis without nasal polyps, and acute bacterial rhinosinusitis (P = .017, .009, .002, respectively) and in reducing post-nasal drip in those with acute bacterial rhinosinusitis (P = .040). There were no statistically significant differences among devices in patients with chronic rhinosinusitis with nasal polyps. CONCLUSIONS: Nasal irrigation with high-volume devices was an effective treatment for rhinosinusitis and was more effective at clearing nasal secretion and reducing post-nasal drip than that with other types of devices. LEVEL OF EVIDENCE: 2C.

Rhinofacial entomophthoramycosis case series, the unusual cause of facial swelling.

BACKGROUND: Rhinofacial entomophthoramycosis is a specific fungal infection of the skin and subcutaneous tissue. It is considered as a rare and neglected disease in tropical and subtropical areas. We would like to present our cases to aid other physicians in the improved recognition of typical cases. MATERIALS AND METHODS: A retrospective review was performed on patients with the diagnosis of Conidiobolomycosis or Entomophthoramycosis in Chiang Mai University Hospital, Thailand, from January 2009 to May 2019. There were seven cases with a definite pathologic report or culture in this review. RESULTS: All seven patients were men and were referred to the university hospital for diagnosis. The mean age was 53 ± 15.7, ranging from 27 to 71 years. Most of the patients (85.7%) presented first with nasal or rhinofacial swelling and nasal obstruction. The definite diagnosis came from clinical presentation and investigation with a tissue biopsy, culture and communication among physicians. Patients responded well with a combination of medical treatment, including potassium iodide (KI), co-trimoxazole, or itraconazole. CONCLUSION: Rhinofacial entomophthoromycosis or Conidiobolomycosis typically can be diagnosed under a suspicious clinical presentation. The obvious clinical response can be seen within several weeks after medication.

Localised nasopharyngeal amyloidosis: the importance of postoperative follow-up.

Localised nasopharyngeal amyloidosis is rare. Findings on physical examination and invasive pattern on CT scan can be misleading as it can resemble nasopharyngeal carcinoma. A 64-year-old man presented with left aural fullness for 6 months. The physical examination showed straw-coloured fluid in the left middle ear and irregular reddish mass at the left side of the nasopharynx. The CT scan showed a lobulated heterogeneous mass at the left side of the nasopharynx involving the left Eustachian tube opening. Pathology report was amyloidosis, thus, surgery was done. After a year, there were new foci of amyloidosis at the right side of the nasopharynx, and a repeat surgery was performed. Two years later, the systemic amyloidosis with underlying IgG4-related disease was suspected due to multiple organ involvement. Surgery is the treatment for localised amyloidosis with compressive symptoms. Close follow-up is important after surgical excision due to its recurrence and progression to systemic amyloidosis.

Sphenoid Sinus Diseases: A Review of 1,442 Patients.

OBJECTIVE: To review and report diseases of the sphenoid sinus from the literature and from a university hospital. METHODS: Inpatients' data were retrospectively gathered and reviewed from January 2006 to June 2016. Clinical data, imaging, organisms, and pathological reports were collected. Pathology was divided into infection/inflammation, tumor, and miscellaneous. A literature review was performed with the search term "isolated sphenoid disease" in PubMed. Original primary studies with 20 patients or more were reviewed. RESULTS AND DISCUSSION: One hundred and twenty-two patients were enrolled. Seventy-two subjects were female (59%). The average age was 54.3 years (±18.0). Imaging abnormalities were found incidentally in 27 patients (22.1%). The most common symptom was headache (63.9%). Visual loss, the second most common symptom, was more frequent in the tumor group (30.6% versus 54.2%). From the literature review, 21 primary studies with 1,320 total patients were included. From all studies and the present study, infection/inflammation was the most common pathology (75%) [95% confidence interval (CI): 0.696, 0.804]. Overall, tumors were found in 18.9% and malignant tumors in 7.0% [95% CI: 0.045, 0.095]. CONCLUSION: A specific diagnosis of a sphenoid lesion is needed during active investigation. Infection/inflammation was the most common pathology and malignancy was found in 7%.

Antrochoanal Polyps: How Long Should Follow-Up Be after Surgery?

Objective. To investigate the length of follow-up needed to detect recurrence of antrochoanal polyps. Methods. A retrospective investigation was performed on patients who had been operated on with a preoperative diagnosis of antrochoanal polyps in Chiang Mai University hospital from 2006 to 2012. Results and Discussion. Of the 38 cases of choanal polyps, 27 were adults (71%). The median age was 23.5, ranging from 7 to 64 years old. Eighteen patients were male (47.4%). The origin of choanal polyps was the maxillary antrum in 32 patients. The most common symptom was nasal obstruction (97.4%). The surgical procedures were polypectomy in one child and combined endoscopic and transcanine fossa approach in two adults. The remainder of the patients underwent endoscopic removal of the polyps. The follow-up time ranged from 1 day to 8 years. There were 5 cases of recurrence of which four were in children. The time for recurrence was 1.2 ± 0.6 years (95% CI 0.51, 1.97). Conclusion. Antrochoanal polyps are more common in younger patients. Recurrence was significantly higher in children. Follow-up of patients should be for at least 2 years postoperatively in order to detect 95% of recurrence.

Sinonasal papilloma in Chiang Mai University Hospital.

OBJECTIVE: To study sinonasal papilloma patients in terms of clinical characteristics, treatment, outcome, and complications. MATERIAL AND METHOD: A retrospective descriptive study was done. Sinonasalpapilloma data were gathered between 1999 and 2009. There were 63 available patients from the 82 cases. RESULTS: There were nine cases of nasal papilloma (14.3%) and 54 of inverted papilloma (85.7%). The mean age of the inverted papilloma group was higher than the nasal papilloma group (54 +/- 12.97 years vs. 42.4 +/- 24.8 years). The most common symptom was unilateral nasal obstruction. There were three cases of synchronous malignancy in the inverted papilloma and two metachronous (9.3%). Thirty-nine patients (72%) could be followed-up for more than three months. Recurrence was more common in the inverted papilloma group than nasal papilloma (37% vs. 11.1%). The 50% recurrent time of the endoscopic group was 51 weeks and the external group was 14 weeks. The recurrence of the external approach group was 1.59 times the endoscopic group. Ten surgical complications were found in eight inverted papilloma patients (16%) and included three in the endoscopic and five in the external group. Most of them were minor They were hypoesthesia and epiphora. CONCLUSION: Sinonasal inverted papilloma was common, able to recur and associated with malignancy. Though this was a limited retrospective study, it showed lower recurrence on the endoscopic approach. The life-long follow-up is needed in all cases.

Late complications of radiotherapy for nasopharyngeal carcinoma.

OBJECTIVE: To evaluate and assemble late complications of radiotherapy in cases of nasopharyngeal cancer. METHODS: From October 2003 to January 2005, a prospective cohort study was done in a tertiary center, Chiang Mai University Hospital. Two hundred patients were evaluated for late complication according to the RTOG/EORTC late radiation morbidity scoring criteria. RESULTS: Of 200 patients, 131 were male (65.5%) and 69 female (34.5%). The mean age was 49.7+/-13.5 years (11-78). The mean pre- and post-treatment body mass indexes (BMI) were 22.5+/-4 (15-35.6), and 19.8+/-3.2 (12.9-34.5; P<0.05). Mean post-radiation period was 3.6+/-3.4 years (0.3-18.6 years). The radiation dosage ranged from 60 to 76Gy (mean 69Gy). Most of the patients (92%) had undifferentiated (50.5%) and poorly differentiated (41.5%) squamous cell carcinoma. Eighty-eight percent of the patients were in Stage III and IV. Chemotherapy was given to 145 patients (72.5%). The mean post-radiation period in the added chemotherapy group was lower than the group treated with radiation alone (2.9+/-2.7 years vs. 5.4+/-4.4 years, P<.05). The most common complication was dryness of mouth (97.5%); followed by hearing impairment (inner ear 82.5%). Added chemotherapy increased the complication severity significantly for the skin (P<0.05). The mean number of complications was 6.3+/-2.2 (range from 1 to 12). CONCLUSION: In this study, every patient had a more or less adverse reaction to radiation. Doctors need to be aware of these complications in order to prevent serious ones and to improve the patients' quality of life in the long term.

Comparison on the efficacy of dexpanthenol in sea water and saline in postoperative endoscopic sinus surgery.

OBJECTIVE: To compare the efficacy of dexpanthenol spray and saline irrigation in the postoperative care of sinusitis patients following endoscopic sinus surgery (ESS). MATERIAL AND METHOD: One hundred twenty eight sinusitis patients undergoing ESS were randomly allocated to receive dexpanthenol spray (Mar plus) or saline irrigation twice a day for 4 weeks after the operation. Total nasal symptom score, crusting, infection, compliance, and patient satisfaction were evaluated at 1, 2-3, 4-6, and 12 weeks. Mucociliary clearance was assessed with the saccharin test before ESS and at the last visit. One hundred ten patients remained at the present study termination. Chi-square test and Mann-Whitney U test were employed. RESULTS: Total nasal symptom score, mucociliary clearance, and infection improved in both groups after the operation. The dexpanthenol group resulted in a better mucociliary clearance than saline irrigation (9.93 +/- 6.04 vs. 12.38 +/- 9.32 min, p = 0.43). Saline irrigation resulted in a greater reduction of post nasal drip than dexpanthenol at the first visit (74% vs. 87%, p = 0.04). Compliance and patient satisfaction were comparable. CONCLUSION: The efficacy of dexpanthenol was comparable to nasal saline irrigation in the postoperative care of sinusitis patients following endoscopic sinus surgery. Dexpanthenol is an alternative treatment, which may be useful in young children and complicated cases.
