Large Thyroglossal Duct Cyst: A Case Report.

BACKGROUND Thyroglossal duct cysts are the most common congenital neck cysts. They typically present in childhood and early adulthood, and average a size of 2-4 cm, but can also present in later adult life. CASE REPORT We present a case of a 36-year-old female patient with a very large midline neck mass, reaching the mandible superiorly. Patient history and physical examination, as well as computed tomography scan of her neck, confirmed the diagnosis of large thyroglossal duct cyst. She underwent Sistrunk procedure for thyroglossal duct cyst excision, and the specimen was sent for histopathological evaluation, which confirmed the diagnosis. CONCLUSIONS Thyroglossal duct cyst should be considered as a differential diagnosis in older patients and in patients with a relatively large neck mass.

Surgical considerations and speech outcomes in infants who undergo cochlear implantation. Experience of the King Abdullah Ear Specialist Center.

OBJECTIVES: To evaluate the feasibility and outcomes of cochlear implantation (CI) in infancy. METHODS: All infants who underwent CI from January 2011 to October 2018 at a tertiary referral center in the Kingdom of Saudi Arabia were retrospectively reviewed. Demographic data, factors associated with early detection, and any surgical difficulties or postoperative complications were extracted from the medical records. The outcome of CI was determined by a speech pathologist. RESULTS: Fifteen patients underwent CI during the study period (9 bilateral and performed simultaneously, 6 unilateral). The round window was difficult to identify in 5 cases. Incomplete electrode insertion because of cochlear ossification secondary to meningitis was documented in one patient. No major postoperative complications were encountered. The average auditory performance score was 7 and the speech intelligibility rating was 5. CONCLUSIONS: This study represents the largest national cohort of pediatric patients undergoing CI in infancy. In this series, the surgery was safe and the speech outcome was good. With implementation of the neonatal screening program in the Kingdom of Saudi Arabia, the number of infants undergoing CI is likely to increase in the near future, paving the way for more research in infant CI.

Outcomes of Early-stage Glottic Carcinoma Treated with Radiation Therapy: A Single Institution Experience.

OBJECTIVE:  To evaluate the outcomes of radical intent radiation therapy in early glottic carcinoma (EGC), including local control rate (LCR), disease-free survival (DFS), death specific free survival (DSFS), and overall survival (OS) rates, in Saudi patients treated at a single institution.  Materials and methods: This is an institutional review board (IRB) approved, retrospective study of 27 patients with T1-2 N0 M0, early glottic carcinoma (EGC) who were treated from 2010 to 2015 at our institution with different radiotherapy (RT) fractionation regimens. The regimens included six different fractionation schedules of radiotherapy (RT): 50 Gy (20 x 2.5 Gy) dose prescribed to 95% isodose line, 52.4 Gy (20 x 2.52 Gy), 63 Gy (28 x 2.25 Gy), 66 Gy (33 x 2 Gy), and 70 Gy (35 x 2 Gy). The cohort was stratified into two groups, ≤ 52.5 Gy (n=15) and > 52.5 Gy (n=12). The median follow-up of all patients was 31.7 months (range 7-82). RESULTS: The mean age of the cohort was 64.5 years (median 65, range: 41-83). Eleven patients (40.7%) had a history of smoking. The majority of the cohort was with T1a EGC (70.4%, n=19), and anterior commissure invasion was seen in three patients (11.1%). The mean RT doses were 55.6 Gy (range: 50-70). The five-year LCR, DFS, DSFS, and OS rates were 83.1%, 80.0%, 96.2%, and 92.6%, respectively. The LCR rates for those receiving a dose of 52.5 Gy or less were 61.3 months compared to 89.5 months for those who received more than 52.5 Gy (p=0.994). Non-smokers and patients with an unknown smoking history achieved a five-year LCR of 100%, while patients with a positive smoking history achieved a five-year LCR of 60.6% (p=0.044). CONCLUSION:  Radiation therapy for EGC in our patients showed reasonable five-year LCR with larynx preservation at 83.1%, DFS 80.0%, five-year OS rate 92.6%, and DSFS rate 96.2%. We found that smoking had a significant correlation with LCR. However, large prospective trials are warranted to evaluate the efficacy of overall treatment time, dose per fraction of above 2 Gy, and smoking effect.
