Methods
A systematic search of PubMed, EMBASE and Cochrane library was done with
no restriction on publication date (January 2021). The following search
strategy was used: ((nasal surgery OR sinus surgery OR FESS OR
endoscopic sinus surgery OR functional endoscopic sinus surgery OR
septoplasty OR septal surgery OR turbinoplasty OR turbinectomy OR
turbinate reduction OR SMD OR submucosal diathermy OR polypectomy OR
uvulopalatoplasty OR uvuloplasty OR uvulopalatopharyngoplasty OR
supraglottoplasty) AND (apnoea OR apnea OR hypopnoea OR hypopnea) AND
(day case OR day-case OR daycase OR ambulatory OR outpatient OR
discharge)).
Title and abstract from the initial search were screened independently
by two authors (ETT, OE) according to eligibility criteria (Table 1),
and full-text articles were retrieved accordingly and assessed further.
See Table 1 for definitions of individual terms used for the study. Any
discrepancies on study eligibility were discussed among two authors
(ETT, OE) and a consensus reached. References from included full-text
articles were screened to identify further eligible studies.
A standardized data collection proforma was used and this was piloted on
two studies) and revised accordingly. Subsequent data collection was
performed by one author (ETT) and the verification of data accuracy was
performed by another author (WSL). The following data items were
collected: Study characteristics, population demographics including
severity of OSA, type of surgery performed, anaesthetic and/or surgical
techniques if reported, length of follow-up, reported outcomes and
complications. Our main outcomes were the proportion of daycase
discharges in these studies and any respiratory events/complications
that were reported in the follow-up period in each study.
The risk of bias in the included studies was assessed using Murad’s tool
(5).
Due to the heterogeneity of the included studies, we did not perform a
meta-analysis.
This review protocol was registered with PROSPERO database
(CRD42021273451). No ethical approval was needed due to the nature of
the study. PRISMA reporting guideline was used in preparation of the
manuscript.
