Effect of Radiotherapy on Sino-nasal Function in Nasopharynx Cancer Patients.

Introduction: Radiotherapy causes significant nasal comorbidity in nasopharynx cancer (NPC) patients. However, the literature addressing the sino-nasal quality of life (QoL) of those patients, especially on structural and functional changes after radiotherapy, is limited. Method: It is a case-control study with 14 NPC groups and 14 healthy control group. The sino-nasal QoL, including the olfactory threshold using Butanol Threshold Test (BTT), the olfactory identification level using the University of Pennsylvania Smell Identification Test (UPSIT), nasal symptoms using the sino-nasal outcome test (SNOT-22) questionnaire, nasal cross-sectional area, nasal flow, and nasal resistance using the acoustic rhinometry and rhinomanometry, were measured and compared. Result: The mean BTT score of the control group was higher than that of the NPC group (5.17 vs 2.71). The UPSIT score of the control group was higher than that of the NPC group (31.93 vs 25.14). The mean SNOT-22 score of control group was lower than that of the NPC group of (16.71 vs 37.71). All 3 results are statistically significant (P < .05). However, there is no statistical difference in nasal cross-sectional area, nasal flow, and nasal resistance between these 2 groups. Conclusion: In this study, we concluded that NPC patients who received radiotherapy suffered a worsening of sino-nasal functional changes, including the olfaction threshold, olfaction identification, and nasal symptoms. However, the sino-nasal structural changes on nasal cross-sectional area, nasal flow, and nasal resistance after radiation remain questionable.

Endoscopic-assisted retrieval of retained lacrimal stent material in congenital nasolacrimal duct obstruction without dacryocystorhinostomy.

We report a 3-year-old child with history of congenital nasolacrimal duct obstruction who failed lacrimal probing and underwent bicanalicular intubation. Removal of stent from the superior punctum was unsuccessful and it was trapped in the lacrimal sac. We performed endonasal endoscopic-assisted retrieval of retained stent material without necessitating dacryocystorhinostomy (DCR). There was no recurrence of infection and nasolacrimal duct obstruction symptoms during 6 months of follow-up.

A prospective randomised controlled study on efficacies of acupuncture and steroid in treatment of idiopathic peripheral facial paralysis.

OBJECTIVE: A randomised controlled trial was undertaken to evaluate the efficacy of acupuncture in comparison with steroid in treatment of idiopathic peripheral facial paralysis (Bell's palsy). METHODS: A total of 119 patients attending Ear, Nose and Throat Clinic of Pamela Youde Nethersole Eastern Hospital from February 2003 to December 2005 were randomly allocated to groups of acupuncture, steroid and control (conventional expectant treatment). There were 53 in the steroid group, 28 in the acupuncture group and 38 in the control group. Patients were assessed weekly by blinded assessors, using the House-Brackmann facial nerve grading system. RESULTS: The efficacy of treatment in three groups was compared, in terms of degree of recovery and speed of recovery. Intention-to-treat analyses were performed. Results were analysed with SPSS software. Distribution of initial grade on presentation was analysed with the Pearson chi-square test and showed uneven distribution in the three groups in the intention-to-treat analysis. The overall improvement (grade 3 or better) was 86.9% in the steroid group, 96.4% in the acupuncture group and 89.5% in the control group respectively. However, the difference in degree of recovery and speed of recovery in the three groups was not statistically significant. CONCLUSION: The efficacies of acupuncture, steroid and conventional expectant treatment (natural course of recovery) in idiopathic peripheral facial palsy (Bell's palsy) in the study were the same with respect to the degree of recovery and speed of recovery.
