INTRODUCTION The optimal treatment of cervicofacial nontuberculous mycobacterium lymphadenitis (CFNTB) in children is yet to be established. There is a general consensus that surgical excision results in a definitive resolution of the disease. The main aim of surgery is to remove affected nodes so that they do not discharge through the skin. Recently there are some investigators who are reporting successful antibiotic treatment and advocating medical therapy as the first line treatment. METHODS 16 children consecutively presenting to otolaryngology in a tertiary referral centre over an 8-year period with CFNTB. Inclusion criteria were chronic cervicofacial lymphadenitis with either: (1) a culture positive for atypical mycobacteria (from either a lymph node or fine needle aspirate (FNA) specimen); or (2) acid-fast bacilli identified (from either a lymph node or FNA specimen); or (3) post excision histological findings consistent with mycobacterial infection (i.e. non-caseating granulomas) in the absence of other clinical features suggestive of other granulomatous conditions. Lesions with superficial skin change were treated preferentially with surgery. Children presenting with lymph nodes contained deep to sternocleidmastoid were assessed with FNA cytological and microbiological analysis and MRI or CT, and treated preferentially with antibiotics or watchful waiting. RESULTS 4 children (2 culture positive, 2 with acid-fast bacilli on needle aspirate) presented with lymphadenopathy deep to sternocleidmastoid and were managed non-surgically. All 4 resolved without cutaneous involvement. 11 children with a clinical presentation of CFNTB underwent complete excision of all involved nodes for superficial lesions (6 were culture positive, and all had granulomatous histology). None recurred. 1 patient presented late with a mature, discharging parotid sinus, which was managed with watchful waiting as the lesion was clinically close to natural resolution. CONCLUSIONS Depth at presentation may help decide which patients with CFNTB can be treated non-surgically without cutaneous sequelae. We propose that a watch and wait management is an option for deep nodes.

OBJECTIVES The management of third branchial pouch anomalies has evolved in recent times with the popularisation of the endoscopic diathermy technique to sclerose the pyriform fossa sinus opening. We present our experience in managing 3 children with third branchial pouch anomalies and propose a minimally invasive management algorithm avoiding open neck surgery. METHODS Retrospective case review of 3 patients including demographics, mode of presentation, investigations, management and complications. RESULTS Three children, two male and one female of mean age 9.6 years presented with painful left anterior neck swelling. Axial neck imaging showed a superficial abscess with air locules and a sinus tract leading towards the left pharynx. Diagnosis was confirmed by endoscopic examination of the pyriform fossa revealing a sinus opening. Two patients underwent open excision; one combined with diathermy to the sinus opening. The last patient was diagnosed at his initial presentation and managed with endoscopic diathermy of the sinus opening combined with percutaneous needle aspiration of the neck abscess at the same sitting. One patient had two recurrences, the first after initial open surgery and the second after the first cautery. Two patients developed temporary hoarseness after the procedure, which resolved within two weeks. All patients were free from recurrences at follow-up. CONCLUSIONS Introduction of the technique of endoscopic diathermy to the pyriform fossa sinus opening in children with third branchial pouch anomalies has revolutionised their management avoiding open and potentially morbid surgery. Our algorithm takes this further by advocating percutaneous needle aspiration of the infective component and performing diathermy to the sinus opening at the first presentation.
