Both excessive sleepiness and insomnia were seen in high proportions of the patients referred on suspicion of OSA. Excessive sleepiness was higher whereas insomnia was lower with greater OSA severity.

Sarcoidosis is a chronic systemic disease of unknown etiology characterized by non-caseating inflammation involving one or more organs with predilection for pulmonary and upper respiratory tract involvement. It presents with a variety of signs and symptoms which can be generalized or focused on a single organ. Sinonasal involvement is reported in about 1% of cases of sarcoidosis. Sarcoidosis can involve both the mucosa as well as bony structures in the nose and the paranasal sinuses. We present seven cases of sarcoidosis with sinonasal involvement. Four cases presented with nasal and sinus symptoms, and the other three cases developed or presented with nasal and sinus symptoms after the diagnosis of sarcoidosis was confirmed. The nasal and sinus symptoms in these patients were managed by local and systemic steroids. In four patients, endoscopic sinus surgery was performed with good outcome. Nasal and sinus symptoms, differential diagnosis and the treatment are discussed.

ABSTRACT.Purpose: To evaluate the outcome of endoscopic decompression in a series of patients with thyroid eye disease. Methods: All 46 patients operated at our institution in the period 2001 to 2011 were invited for re-examination. Thirty-seven patients were included in the study and underwent a general otorhinolaryngological and ophthalmological examination. Nasal endoscopy, autoperimetry and a CT scan of the orbits and paranasal sinuses were performed. Preoperative and early postoperative data were obtained from hospital records. Re-examination was performed from 12 months to 9 years postoperatively. Paired t-test was used to evaluate the change in pre-and postoperative data. Image-guided surgery was used in two patients. Results: Visual acuity improved from a median value (range) of 0.8 (0.05-1.25) to 1.0 (0.4-1.25) (p = 0.006). Intra-ocular pressure (IOP) was reduced from a median value (range) of 18 mmHg (10-27 mmHg) to 14 mmHg (8-24 mmHg) (p < 0.001). Median (range) Hertel values were 22.5 mm (14-29 mm) preoperatively and 19 mm (11-26 mm) postoperatively (p < 0.001). Mean reduction in proptosis was 4.0 mm. At follow-up, visual fields were normal in 16/37 patients (43%) and with small defects in 12/37 patients (32%). Seventeen patients (46%) had diplopia preoperatively in one or more directions of gaze while 9 (24%) suffered from constant diplopia. After endoscopic decompression, new onset diplopia was seen in seven (19%) individuals, while worsening of diplopia occurred in eight (22%). Impaired motility in abduction and/or elevation was seen in 20 (54%) individuals before decompression and in 23 (62%) after. Strabismus surgery was performed in 22 patients. On final examination 85% of the study population were totally free of diplopia or experienced diplopia only in the peripheral field of gaze. Three patients developed sinusitis. Of these, endoscopic sinus surgery was performed in two patients, and one patient was conservatively treated. Symptoms resolved in all three patients. Conclusion: Endoscopic medial orbital decompression including removal of the medial floor of the orbit is a safe and effective procedure for treatment of thyroid eye disease. Navigation can be of valuable help to ensure complete resection of the bony walls. However, the majority of patients will need subsequent strabismus surgery, mainly due to significant increase of esotropia.

Mandibular setback surgery with the IVRO procedure in the range of 2.5 to 7.4 mm did not induce obstructive sleep apnea, measured as an AHI above 5 events per hour, in the 8 healthy, young adult Class III patients presented in this study. More studies including larger patient samples are needed.

The impact of obstructive sleep apnea (OSA) on arterial stiffness is less studied.We aimed to investigate the prevalence and covariates of increased pulse pressure (PP), a surrogate marker of arterial stiffness, in the entire study population as well as in separate analyses in normotensive and hypertensive patients. Further, we also explored the impact of smoking on brachial BP in hypertensive patients. Between 2012 and 2019, a total of 6408 participants with suspected OSA underwent a standard out-of-center respiratory polygraphy. OSA was defined by an apnea-hypopnea index (AHI) ≥15/h regardless of symptoms. PP ≥60 mmHg was used as a surrogate marker of increased arterial stiffness. Mean age was 49.3±13.7 years, 69.4% were male, and 34.5% had OSA. The prevalence of hypertension was 70.8% in OSA and 46.7% in No-OSA (AHI < 15/h) controls (P < .0001). Hypertension was controlled (clinic BP < 140/90 mmHg) in 45.5% and uncontrolled in 54.5% (P < .001). Mean PP was 50±12 mmHg in smokers and 52±12 mmHg in non-smokers (P = .001). Increased PP was found in 24.2% of the entire study population and was higher in patients with OSA compared to No-OSA group (27.5% vs 22.4%, P < .0001). In an unadjusted logistic regression model, OSA was associated with a 1.3-fold higher risk of having increased PP (95% CI 1.16-1.48, P < .001). In a multivariable-adjusted model, higher age, male sex, and history of hypertension, but not OSA (OR 0.89; 95% CI 0.77-1.02, P = .104) were associated with increased PP. In this large study of nearly 6500 participants who were referred with suspected OSA, one-third were diagnosed with OSA and a quarter had increased arterial stiffness by elevated brachial PP. Hypertension but not OSA per se was associated with increased arterial stiffness. Hypertension was highly prevalent and poorly controlled.
