Temporal bone fractures are a common lesion of the base of the skull. The diagnosis and management of temporal bone fractures require a multidisciplinary approach. Variable clinical presentations may arise from such fractures, ranging from an asymptomatic course to very serious consequences. The aim of this study was to report our experience with a series of patients with temporal bone fractures and to propose a diagnostic/therapeutic algorithm. This study enrolled 141 patients, 96 (68.1%) males and 45 (31.9%) females, ranging in age from 20 to 60 (average age: 39 ± 4.1 years), with temporal bone fractures who were referred to Cardarelli Hospital between 2006 and 2018. The present paper presents a classification of temporal bone fractures and typical clinical sequelae and provides an illustration of their prognosis and treatment.

To determine the utility of the hyperventilation test (HVT) in the diagnosis of vestibular schwannoma (VS). A retrospective analysis of hyperventilation-induced nystagmus (HVIN) in 45 patients with unilateral VS. A tertiary referral center. Forty-five patients with VS; 30 patients with chronic vestibular neuritis; 20 healthy subjects with normal hearing and without symptoms or a history of vertigo, migraine, or neurological diseases (control group). Audiological and vestibular examination; "side-stream" measurement of end-tidal CO2 pressure (P(EtCO2)) to standardize the procedure; magnetic resonance imaging (MRI) centered on the cerebellopontine angle. An analysis of HVIN, its patterns, and its appearance threshold via the measurement of P(EtCO2) correlations with the tumor size. HVIN was observed in 40 of 45 cases (88.9%) in the schwannoma group and in 12 of 30 cases (40%) in the chronic vestibular neuritis group; HVIN was not observed in the control group (0/20 cases) (p < 0.001). In the schwannoma group, HVIN was evoked at a mean P(EtCO2) value of 16.5 ± 1.15 mm Hg. The hypofunctional labyrinth was identified with high sensibility and specificity through caloric test, head shaking test, and head thrust test. The excitatory pattern, which included HVIN with slow phases that beat toward the hypofunctional side, and the paretic pattern, which included HVIN with slow phases that beat toward the hypofunctional side, were not significantly associated with VS size (19.04 ± 10.56 mm for the excitatory pattern and 19.06 ± 11.01 mm for the paretic pattern). The difference in the VS size in HVIN+ (19.05 ± 10.60 mm) and HVIN- (8.40 ± 2.19 mm) cases was significant (p = 0.009). A 60-second hyperventilation event causes metabolic changes in the vestibular system and reveals a latent vestibular asymmetry. The presence of an excitatory pattern is the major criterion that suggests VS in patients with signs of unilateral vestibular deficit.

Objective: The aim of this study was to assess the long-term effectiveness of quantic molecular resonance (QMR) in the treatment of inferior turbinate hypertrophy (ITH) in allergic and nonallergic rhinitis refractory to medical therapy. Methods: This study enrolled 281 patients, 160 males (56.9%) and 121 females (43.1%), mean age 37.8 ± 4.1 years, range 18 to 71. Fifty-four patients have been lost to follow up and have been therefore excluded from the final analysis. Based on skin prick test results, 69 patients were considered allergic (group A) and 158 nonallergic (group B). All subjects underwent before surgery (T0) and 3 (T1), 12 (T2), 24 (T3), and 36 months (T4) after QMR treatment to: 4-phase rhinomanometric examination, nasal endoscopy evaluation, and visual analogue scale to quantify the subjective feelings about nasal obstruction. Results: Subjective and objective parameters showed statistically significant improvement in both groups. Group B parameters not changed during follow-up, while group A showed significant worsening between T1 and subsequent assessments. T4 outcome indicates a better result in nonallergic patients. Conclusions: In accordance with the literature, our preliminary data validate QMR treatment as a successful therapeutic option for nasal obstruction due to ITH. Nonallergic patients had a very good T4 outcome. Allergic patients showed a worsening trend after 1 year probably due to other causes.
