Objective: This study aimed to measure nasal airway resistance (NAR) in obstructive sleep apnea (OSA) patients with nasal obstruction using active anterior rhinomanometry (AAR) and to evaluate whether NAR can predict the indication to include septoplasty as an additional procedure alongside drug-induced sleep endoscopy (DISE) and inferior turbinoplasty. Methods: We performed a retrospective observational study in OSA patients with nasal obstruction. According to nasal endoscopy and CT findings, patients were planned for either DISE with inferior turbinoplasty alone or DISE with inferior turbinoplasty and septoplasty. All patients underwent preoperative AAR, carried out under baseline and post-decongestion conditions. To test the ability of NAR to predict septoplasty indication, receiver operating characteristic (ROC) curves were generated for baseline and post-decongestion values. Logistic regression combined inspiratory/expiratory and unilateral/total NAR. The Area Under the Curve (AUC) was used to evaluate diagnostic accuracy, and optimal cut-offs were identified using Youden’s index (J). Results: Forty-eight patients were included. Baseline NAR showed low accuracy (median AUC: 0.540 unilateral, 0.562 total) and no valid cut-offs were identified (median J: 0.213 unilateral, 0.233 total). Post-decongestion NAR performed better (median AUC: 0.649 unilateral, 0.738 total). Inspiratory and expiratory unilateral values merged with binary regression improved prediction (AUC 0.677 and 0.709). The highest accuracy was achieved when all rhinomanometric parameters were integrated into one logistic model (AUC = 0.947). Conclusions: Preoperative AAR may help refine nasal surgical planning during DISE in OSAS patients, supporting a personalized approach and potentially reducing the need for staged nasal procedures.

We present the clinical case of a 51-year-old male patient, affected by common variable immunodeficiency (CVID). In his history recurrent orbital cellulitis, exacerbation of chronic right dacryocystitis, lacrimal sac empyema with periodic episodes of dacryocutaneous fistolization. The coexistence of these particular immunological defects and the lack of literature about similar cases required an accurate evaluation of each step of the diagnostic and therapeutic approach. We performed an endoscopic endonasal dacryocystorhinostomy with “cold” instruments. No surgical complications were observed in the immediate postsurgical period. We balanced the necessity of a follow-up based on frequent office evaluation and the current pandemic emergency, in order to not expose the patient to an additional infectious risk. The discussion will focus on several aspects: the adequacy of radiological, the “cold” surgical technique, the choice of avoiding endocanalicular prostheses. We will discuss also about the use of oral and topical therapy, avoiding probable post-surgical infectious complications.

Introduction: Obstructive sleep apnea syndrome (OSAS) is caused by anatomical and non-anatomical factors which lead to upper airway (UA) obstruction during sleep. Intrinsic UA collapse is the most frequent determinant of OSA. In the era of personalized medicine, adopting a tailored diagnostic approach is essential to rule out secondary causes of UA collapse, particularly those stemming from extrinsic anatomical factors. Although being rarely considered in the differential diagnosis, space-occupying lesions of deep cervical spaces such as the parapharyngeal space (PPS) may be responsible for airway obstruction and lead to OSAS. Objective: This study aimed to present an atypical case of OSAS caused by extrinsic PPS compression, outlining the relevance of modern personalized medicine in the diagnostic and therapeutic protocols, and to enhance understanding through a comprehensive literature review. Methods: A 60-year-old female presented with sleep-disordered complaints and was diagnosed with severe OSAS after polysomnography. At physical examination, a swelling of the right posterior oropharyngeal mucosa was noticed. Imaging confirmed the suspicion of a PPS tumor, and transcervical resection was planned. Case presentation was adherent to the CARE checklist. A comprehensive literature review was conducted using the most reliable scientific databases. Results: Surgery was uneventful, and the patient made a full recovery. The histopathology report was consistent with the diagnosis of pleomorphic adenoma. Postoperative outcomes showed marked improvement in polysomnographic parameters and symptom burden. Conclusions: Parapharyngeal space tumors are a rare, often overlooked cause of OSA. This case highlights the role of a personalized head and neck assessment in OSA patients, particularly in identifying structural causes and offering definitive surgical management when indicated.
