Transoral microlaryngoscopic approach for schwannoma of the larynx.

Neurogenous tumors of the larynx are extremely rare. We present a 66-year-old male patient who underwent surgical excision of schwannoma of the larynx, which originated from the left aryepiglottic fold. Excision of the mass was performed through an endolaryngeal approach (suspension microlaryngoscopy). In the early postoperative period, the patient was breathing comfortably and his swallowing and phonation were normal. During a follow-up of three years, no evidence for recurrence was detected and he had no complaints of dysphagia, globus sensation, dyspnea on exertion, or cough.

Audiovestibular functioning in patients with panic disorder.

OBJECTIVE: The objective of this study was to investigate audiovestibular function in patients with panic disorder and healthy subjects by using vestibular and audiologic tests. METHODS: Thirty-four panic disorder patients and 20 healthy control subjects were assessed by using clinical otoneurological examination, pure tone audiometry, tympanometry, and electronystagmography (ENG). All patients were evaluated with the Panic and Agoraphobia Scale (PAS), the Hamilton Anxiety Rating Scale (HARS), the Hamilton Depression Rating Scale (HDRS), and the State-Trait Anxiety Inventory (STAI). RESULTS: On vestibular testing, abnormal responses were more prevalent in panic disorder patients compared to healthy controls. The presence of agoraphobia in panic disorder patients did not make a significant difference on vestibular test results. The only variable that may be a predictor of vestibular abnormalities in panic disorder patients was found to be dizziness between attacks. CONCLUSION: The results show that dizziness between panic attacks may warrant audiovestibular testing among other medical investigations.

Extracapsular spread in ipsilateral neck and contralateral neck metastases in laryngeal cancer.

We investigated the incidence of extracapsular spread (ECS) and the impact of ECS on contralateral neck metastasis in 67 patients with ipsilateral nodal metastasis (IpN+) whose records were extracted retrospectively from those of 155 laryngeal cancer patients. The incidence of ECS in association with variables was determined: T stage, N stage, tumor location, tumor extension, number of positive nodes, and contralateral neck status. The variables were evaluated to identify their impact on the rates of contralateral neck metastasis (CNM) and 3-year survival. Of the 67 patients, 30 (44.7%) had ECS. A significant relationship was found between ECS positivity and increased N stage, tumor extension up to the midline, number of positive nodes, and CNM (p = .04, p = .0001, p = .018, p = .0001, respectively). Multivariate analysis revealed that N stage (p = .002; odds ratio, 3.5517) and the presence of ECS (p = .0036; odds ratio, 7.7840) in IpN+ were associated with the greatest risk of CNM. The 3-year survival rate of patients with ipsilateral ECS was significantly lower than that of patients without ECS (43% versus 81%, p = .0002). Both CNM and presence of ECS in IpN+ emerged as significant independent predictors for survival with Cox multivariate analysis (p = .0086 and p = .0234, respectively). This result indicates the necessity of treating the contralateral N0 neck in cases of IpN+ with ECS.

[Primary carcinoma of the subglottic larynx].

OBJECTIVES: Primary carcinoma of the subglottic larynx is very rare. This study was designed to evaluate patients who were treated for primary carcinoma of the subglottic larynx. PATIENTS AND METHODS: The study included 15 patients (14 men, 1 woman; mean age 62.8 years; range 45 to 95 years) with primary subglottic carcinoma. Correlations of different clinical parameters with three-year survival rate and Kaplan-Meier survival analysis were investigated. RESULTS: On presentation, two patients (14%) had T1, five patients (33%) had T2, three patients (20%) had T3, and five patients (33%) had T4 tumors. The overall three-year survival rate was 73.4% (11/15). The median survival calculated by the Kaplan-Meier method was 45 months. No significant differences were found between the survival rates of patients with and without extralaryngeal extension. CONCLUSION: Although primary subglottic cancer is locally aggressive with high tendency to extend to the extralaryngeal compartment at the time of diagnosis, high survival rates can be expected when appropriate treatment modalities are selected.
