This study showed a single application of boric acid powder following external auditory canal irrigation until the perforation was visible to be as effective as the current best practice of topical quinolone eardrops in active chronic otitis media. Boric acid powder is inexpensive and does not require patient compliance. Boric acid powder is a viable, less costly alternative to topical antibiotic/steroid ear drops in the developing world for active chronic otitis media. Acetic acid eardrops 1% are ineffective. Quadriderm cream, given as a one-off therapy, also appears to be effective.

Conclusions: The 17% missed appointment rate is largely due to transport constraints. The commonest time for patients to miss appointments is the 6-12 month follow-up period. The authors seek to identify patients at risk of missed appointments and suggest interventions to decrease this incidence.

Submandibular gland metastasis from head and neck primary squamous cell carcinoma is extremely rare. Preservation of the ipsilateral submandibular gland during neck dissection is oncologically safe, except in patients with prior surgery or radiotherapy, or a primary tumour in close relation to the gland.
