Guidelines for the Use of Botulinum Toxin in Otolaryngology From the Korean Society of Laryngology, Phoniatrics and Logopedics Guideline Task Force.

The Korean Society of Laryngology, Phoniatrics and Logopedics created a task force to establish clinical practice guidelines for the use of botulinum toxin (BT) in otolaryngology. We selected 10 disease categories: spasmodic dysphonia, essential vocal tremor, vocal fold granuloma, bilateral vocal fold paralysis, Frey's syndrome, sialocele, sialorrhea, cricopharyngeal dysfunction, chronic sialadenitis, and first bite syndrome. To retrieve all relevant papers, we searched the CORE databases with predefined search strategies, including Medline (PubMed), Embase, the Cochrane Library, and KoreaMed.

Phase II trial of individualized/dynamic cisplatin regimens for definitive concurrent chemoradiation therapy in patients with head and neck squamous cell carcinoma.

The current standard cisplatin regimen for concurrent chemoradiation therapy (CCRT) involves generalized static administration of cisplatin without considering patient characteristics and patient/tumor responses during treatment. We aimed to evaluate the oncological feasibility of individualized/dynamic cisplatin regimens for definitive CCRT in patients with head and neck squamous cell carcinoma (HNSCC). This prospective, single-center study enrolled patients with biopsy-confirmed HNSCC for whom CCRT was indicated as the primary treatment.

Comparison of the Retroauricular Approach and Transcervical Approach for Excision of a Second Brachial Cleft Cyst.

Purpose: Although a retroauricular (RA) approach has been proposed for excision of a second brachial cleft cyst (BCC), no studies have performed a direct comparison of the results of the RA approach and those of the conventional transcervical approach. We evaluated the surgical outcomes of the RA approach under direct vision and demonstrate its benefits compared with the conventional transcervical approach for excision of a second BCC.

Patients And Methods: From January 2012 to May 2016, we enrolled 30 consecutive patients with a second BCC who underwent surgical excision as a primary treatment into the present prospective case-control study.
