Article Synopsis
  • Most thyroid nodules are benign, but differentiating between benign and malignant nodules can prevent unnecessary surgeries; this study focused on a genetic classifier's performance for indeterminate thyroid nodules in Southeast Asia.
  • The study involved 132 patients and utilized ThyroSeq v3 for molecular testing on FNA samples, revealing that 56% of the nodules were histologically malignant, with varying mutation characteristics compared to North American patients.
  • The genomic testing showed a 42% potential avoidance of surgery for patients with Bethesda category III-IV nodules, indicating that molecular testing was a stronger predictor of malignancy than traditional clinical factors.

The nose is frequently traumatized in facial injuries and this often results from motor vehicle accidents, sports-related injuries, and altercations. Subsequently, posttraumatic nasal deformity is one of the most common reasons that patients seek consultation in the doctor's office. Depending on the type of nasal deformities, this can result in functional impairment and aesthetic problems.

Background: We present a case report of a professional diver who sustained a fracture of the left orbital medial wall as well as floor exceeding 50% with orbital fat herniation blocking the maxillary sinus ostium. This may result in a closed cavity within the maxillary sinus that could potentially result in barotraumas during future diving. The aim of his surgery consists of repairing the orbital fracture and to aerating the sinus at the same sitting.

Retropharyngeal lipomas are rare tumours that are usually asymptomatic until they reach a large size. The definitive treatment is surgical excision. Since the tumours are typically large at the time of presentation, extensive surgery for complete clearance of the lipoma from the retropharyngeal and parapharyngeal regions is to be expected.

Objective: Esthesioneuroblastoma is an uncommon tumor that is described widely among the Caucasians. In Singapore, we see predominantly Asian patients with esthesioneuroblastomas. From our experience, we note significant and interesting differences between our data on Asian patients and the published ones on the Caucasian patients.

Objectives: The objectives of this study were to compare the prevalence of submandibular gland neoplasia in an Asian population with a Western population and to evaluate the accuracy of fi ne needle aspiration cytology (FNAC) and computed tomography (CT) scan in the study of submandibular gland pathologies.

Materials And Methods: We conducted a 10-year retrospective review of 101 submandibular mass excisions. Data on the demographic profi le of patients, clinical features, correlation of fi ne needle aspiration cytology, CT scans and histology and morbidities related to surgery were collected.

Introduction: We report a case of successful rehabilitation of hearing with a cochlear implant in a patient with nasopharyngeal carcinoma who developed post-irradiation hearing loss following treatment.

Clinical Picture: A 55-year-old Chinese lady suffered from radiation-induced sensorineural hearing loss due to treatment for nasopharyngeal carcinoma. Audiological tests and imaging studies showed an intact retrocochlear pathway.

Objectives: Repair of nasal septal perforation is a challenging procedure. Numerous methods have been described to close nasoseptal perforations with varying degrees of success. The lack of a consensus on nasoseptal perforation repair reflects the shortcomings of each method.

Objective: Over the past 2 decades, tracheotomy in children and infants has evolved from a primarily emergent procedure for upper airway obstruction into a semielective procedure for airway access in assisted ventilation. We present a 12-year retrospective review of tracheotomies performed in the pediatric population in Singapore.

Study Design And Setting: We reviewed all tracheotomies performed in children below the age of 16 years in 2 tertiary pediatric medical centers in Singapore from January 1991 to December 2003.
