Effects of Olfactory Training in Patients with Olfactory Loss

The authors speculate that training may improve olfactory function. A group of 56 patients with olfactory dysfunction were identified. One group was offered training while another was not. At baseline, the two groups were not significantly different. In contrast, the trained patients increased olfactory function approximately 30% over 12 weeks. See page 496

Transoral Resection of Tonsillar Squamous Cell Carcinoma

The authors report a retrospective study of 102 patients who underwent transoral resection of the tonsillar fossa with neck dissection to treat tonsil cancer. 83% had advanced (Stage III/IV) disease. Adjuvant therapy was administered to 72% based upon pathologic findings. Local control, regional control, and 5 year disease-specific survival were 91.8%, 97%, and 93.9%, respectively. Functional results were excellent with 86% able to achieve a normal diet. See page 508

Frequency of a Dental Source for Acute Maxillary Sinusitis

In a retrospective study of 101 CT scans of patients with acute maxillary sinus, the authors report that a radiographically identifiable odontogenic source of infection such as a projecting tooth root, a periapical abscess, or an oroantral fistula were commonly associated with acute maxillary sinus disease. The likelihood of an odontogenic source increased with the severity of the sinus abnormality. See page 580

Short and Long-Term Usage of Dental Device in Sleep Apnea Syndrome

This prospective cross-sectional study evaluated the effectiveness of an anterior mandibular positioning (AMP) device in management of obstructive sleep apnea. Sleep studies were performed on 38 patients before and 2 weeks after continuous use of the AMP device. Patients with significant dental disease were excluded. Prior to treatment, the mean AHI was 35.5 ± 17.7. Following treatment, the mean AHI was 22.7 ± 15.8 (p = 0.01). 1-year follow-up demonstrated continued compliance by 71% of patients. No dental injuries attributable to long-term use were reported. See page 585

On the Cover

Results of medialization thyroplasty are affected by displacement shim location. In the excised larynx prepared for thyroplasty (Figure 1), an experimental set-up (Figure 2) allowed direct aerodynamic and acoustic measurements assessing the impact of displacement at three sites along the anterior-to-posterior vocal fold axis. Posterior displacement resulted in greatest overall improvements. Mid-to-anterior displacement reduced work of phonation most with less shim force. Combining these results with intra-operative voice monitoring may allow tailoring shim location to patient goals. For further reading, please see the article on page 591 by Czerwonka et al.
