To document that commercially available topical gentamicin-containing eardrops carry a risk of ototoxicity if they reach the middle ear through a tympanic membrane defect. ⋯ Physicians should consider the potential for ototoxicity if gentamicin-containing eardrops (and by extrapolation all topical aminoglycoside drops) are used for longer than 7 days in patients with a tympanic membrane defect. These preparations should not be used in the presence of healthy middle ear mucosa and should be discontinued shortly after the discharge has stopped. It is important to recognize that toxicity is primarily vestibular rather than cochlear.

To define the most effect treatment plan of patients with oral cavity squamous cell carcinoma with clinically negative (NO) neck staging. ⋯ T1 tumors do well with neck treatment other than careful observation. The data suggest that patients with T2 and T3 oral squamous cell carcinoma should undergo surgical resection of their primary tumor site and elective neck dissection. Patients with T4 oral cavity lesions should routinely undergo neck dissection.

The combination of intravenous sedation and local infiltration anesthesia is routinely utilized in otologic surgery. Advantages over general anesthesia with endotracheal intubation include ease and speed of induction and emergence, safety, and decreased postoperative discomfort. Anatomic and physiological patient constraints may preclude the use of intravenous sedation and anesthetists inexperienced in this technique may find it difficult to achieve a consistent level of anesthesia appropriate for major otologic surgery. Administration of anesthesia using the laryngeal mask airway (LMA) has been proposed to offer many of the advantages of intravenous sedation with less risk of oversedation and obstructive apnea. ⋯ The laryngeal mask airway is a safe and effective means of providing anesthesia during major otologic surgery.
