Background: Distraction osteogenesis maxillary expansion (DOME) is an emerging surgical concept for obstructive sleep apnea patients with a high-arched and narrow hard palate presenting with nasal obstruction. Herein we demonstrate the feasibility of DOME in the treatment of patients with persistent nasal obstruction after primary septoplasty.
Methods: A total of 32 consecutive patients with persistent nasal obstruction after septoplasty who underwent DOME were enrolled in this study. The efficacy of DOME in treating persistent nasal obstruction in septoplasty failure patients was evaluated using the validated Nasal Obstruction Symptom Evaluation (NOSE) scale. Pre- and postoperative computed tomography (CT) scans were performed to measure the change of nasal floor width after surgery.
Results: NOSE score improved significantly from 13.62 ± 4.74 to 5.15 ± 3.50 (p < 0.001) after DOME. The postoperative CT scan showed a significant increase of the nasal floor width from 22.4 ± 4.21 to 28.06 ± 4.52 (p < 0.01). No patient had major complications such as wound infection, oronasal fistula, sinusitis, loss of incisor teeth, or malunion.
Conclusion: We found that DOME appears to improve persistent nasal obstruction after septoplasty in patients with a narrow and high-arched hard palate.

Background: SARS-CoV-2 infection is generally associated with less severe forms of disease in children, where most cases only require symptomatic treatment. However, there is a paucity of information regarding the impact and clinical course of COVID-19 in neonate patients. This study aimed to analyze the epidemiological and clinical aspects of COVID-19 in this particular age group who were patients treated in our department.

Nasal airway obstruction is a frequent complaint in an otolaryngology clinic and is often multifactorial. Anatomic contributors may include a nasal septal deviation, inferior turbinate hypertrophy, and nasal valve compromise. Septoplasty and inferior turbinate reduction are one of the most common procedures performed by an otolaryngologist.

Purpose: To compare the nasolacrimal and nasal anatomical parameters in cases of acquired primary nasolacrimal duct obstruction and acute dacryocystitis.
Methods: The study included 62 eyes of 31 patients. The eyes were divided into three groups: Group A, comprising eyes presenting with acute dacryocystitis; Group B, comprising eyes with nasolacrimal duct obstruction but no previous episodes of dacryocystitis; and Group C, comprising eyes with an patent nasolacrimal duct.

The internal nasal valve, the narrowest portion of the nasal airway, is prone to collapse and is often targeted for improvement in nasal reconstruction and rhinoplasty. Endonasal techniques can reduce surrounding trauma and reduce operative times compared to traditional open methods. Options include the use of spreader, butterfly and alar batten grafts, suspension and flaring sutures, and Z-plasty for scarring.

The saddle nose deformity is associated with dorsal collapse and can have both function and cosmetic problems. The saddle nose can cause nasal obstruction by narrowing the nasal cavities, eliciting dynamic internal and external nasal valve narrowing, and abnormally widening the internal and external nasal valves altering airflow dynamics, sinonasal passageways, and olfaction. The saddle nose is challenging to treat due to skin contracture, lack of donor tissue, and difficulties in esthetic integration.
