ABSTRACT
KEY POINTS: Intralesional cidofovir injections in combination with surgery is an effective treatment for recurrent multifocal sinonasal exophytic papilloma. No malignant transformation has been observed in our experience. Anosmia is a potential side effect that patients should be aware of.
ABSTRACT
OBJECTIVE: To study the efficiency of lingual tonsillectomy (LT) as part of multilevel surgery in children with complex obstructive sleep apnea (OSA). To evaluate the safety and the outcomes of LT. STUDY DESIGN: Retrospective case series. SETTING: Pediatric tertiary care academic center. METHODS: We included all children operated for LT to treat complex OSA, from January 2018 to June 2022. All patients underwent a protocolized drug-induced sleep endoscopy (DISE) followed by a coblation LT, associated with the treatment of all other obstructive sites. Patient demographics, medical history, surgery, and outcomes were reviewed. The efficiency of LT was analyzed exclusively in patients with a preoperative and postoperative sleep study. RESULTS: One hundred twenty-three patients were included. Median age was 8 years (interquartile range, IQR [3-12]). Sixty-five (53%) patients had Down syndrome, 22 (18%) had a craniofacial malformation, and 8 (7%) were obese. LT was associated with adenoidectomy (n = 78, 63%), partial tonsillectomy (n = 70, 57%), inferior turbinoplasty/turbinectomy (n = 59, 48%), epiglottoplasty (n = 92, 75%), and/or expansion pharyngoplasty (n = 2, 2%). Eighty-nine patients underwent a sleep study before and after surgery. The median apnea-hypopnea index (AHI) decreased from 18 events/h (IQR [9-36]) before surgery to 3 events/h (IQR [1-5]) after surgery (P < .001) (patients with a postoperative AHI <1.5 events/h, n = 31, 35%, and an AHI <5 events/h, n = 32, 36%). Seventeen out of 30 (57%) patients could be weaned from continuous positive airway pressure after surgery. Two patients had a postoperative hemorrhage and 2 patients required a transient postoperative reintubation. CONCLUSION: In children with complex OSA, LT as part of a DISE-directed multilevel upper airway surgery, was a very efficient and safe procedure.
ABSTRACT
BACKGROUND: Iatrogenic cerebrospinal fluid leak (iCSF-L) is a major complication of endonasal surgeries whose occurrence is always a potential adverse event due to anatomical variation/asymmetry of the skull base (SB). The aim of this manuscript is to provide a topographical map of iCSF-L and to investigate the role of SB asymmetry in iCSF-L occurrence. METHODS: In this retrospective study, the location of iCSF-L dural defect was studied and compared to patients affected by spontaneous and post-traumatic CSF-L. Considering only iCSF-L, after having collected the SB asymmetry data, the Keros, Gera, distance of the anterior ethmoidal artery from the SB, frontal sinus pneumatization, and Thailand-Malaysia-Singapore score classifications were compared to a control group of patients. RESULTS: A total of 153 CSF-Ls (103 spontaneous, 37 iatrogenic, and 13 traumatic) were included. A significant association was noted (p < 0.001) between the nature of the CSF-L and the areas involved. Considering iCSF-Ls, only the Gera classification was significantly different (p < 0.05) and the most reliable in predicting the risk of dural transgression (AUC = 0.719). CONCLUSIONS: ICSF-Ls present peculiar regional SB involvement with the cribriform plate, with the ethmoidal roof being the most involved. After having assessed the asymmetry of the SB, the Gera classification was the most reliable one.
