AI Article Synopsis
- Radical surgical resection of turbinates negatively affects intranasal air conditioning by altering airflow patterns.
- A numerical simulation of a model nose showed that the removal of turbinates creates a large vortex, which decreases the interaction between air and the nasal walls.
- This results in significantly reduced heating of inspired air, highlighting the importance of turbinate function for proper nasal air conditioning.
Article Abstract
Background: Radical surgical resection of the turbinates leads to a reduced intranasal air conditioning. The aim of this study was to determine the effect of turbinate resection on intranasal heating and airflow patterns using a numerical simulation.
Methods: A bilateral model of the human nose with resection of the turbinates on one side based on a CT-scan was reconstructed. A numerical simulation applying the computational fluid dynamics (CFD) solver Fluent 6.1.22 was performed displaying inspiratory intranasal air temperature and airflow patterns.
Results: Due to resection of the turbinates the airflow pattern is disturbed resulting in a spacious vortex throughout the entire nasal cavity. Hence, contact between air and surrounding nasal wall is less intense. Consequently, intranasal heating of the inspired air is relevantly reduced.
Conclusions: Surgical resection of the turbinates leads to a disturbed intranasal air conditioning. The presented numerical simulation demonstrates the close relation between airflow patterns and heating.

Objectives: To compare longitudinal improvement in nasal obstruction quality-of-life outcomes between medial flap turbinoplasty (MFT) and inferior turbinate submucous resection (SMR) concurrently performed with functional septorhinoplasty.
Methods: Retrospective review of a prospectively collected cohort of patients undergoing functional septorhinoplasty between 2015 and 2022 at a tertiary academic center. Outcomes were assessed using the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire preoperatively and over 12 months postoperatively.

To evaluate the repair protocols for intraoperative cerebrospinal fluid (CSF) leaks after endoscopic endonasal clival malignancy resection (EECR) and to analyze the risk factors of surgical complication. The clinical data of patients who underwent EECR and had intraoperative CSF leaks in XuanWu Hospital, Capital Medical University between January 2012 and January 2024 were reviewed. The pathological results, imaging data, location of the dural defect, degree of intraoperative CSF leaks, repair materials, complications such as postoperative central nervous system (CNS) infections, types of antibiotics used, bacterial culture and drug sensitivity results, secondary repair, and follow-up results were collected.

Objectives: This study aims to compare outcomes of endoscopic submucosal resection Turbinoplasty and partial inferior turbinectomy in the treatment of Chronic inferior turbinate hypertrophy.
Methods: A randomized prospective comparative study was conducted on 40 patients who complained of a minimum 3-month duration of nasal obstruction combined with clinical findings of moderate to severe inferior turbinate hypertrophy. Patients were divided into two groups: Group A (Endoscopic submucosal resection Turbinoplasty), and Group B (partial inferior turbinectomy) Which included 20 patients in each group.

Department of Otorhinolaryngology, The University of Tokyo, Tokyo, Japan.
Purpose: This study aimed to validate a method for successful frontal sinus surgery. The method classifies the frontal sinus drainage pathway (FSDP) into five categories based on three bony walls of the anterior ethmoid sinus, including the uncinate process (UP), accessory uncinate process (UPa), and basal lamella of the ethmoid bulla (BLEB), which was tested in actual surgical procedures.
Methods: This study analyzed 53 sides of 48 patients who underwent frontal sinus surgery between October 2022 and March 2023.
