This meta-analysis compares the safety and efficacy of outpatient or day case parotidectomy versus inpatient therapy. The objective of this study is to integrate current information on postoperative complications, readmission rates, and reoperation rates, as well as to assess the methodological quality of existing studies and provide selection criteria for outpatient surgery. We searched PUBMED, SCOPUS, and Google Scholar from January 1980 to January 2025. Search terms included "parotidectomy", "parotid gland surgery", "outpatient", "ambulatory", and "same-day discharge". We considered studies that compared outpatient and inpatient parotidectomy. The primary outcomes studied were postoperative complications, haematoma, seroma, infection, facial nerve injury, readmission, and reoperation rates. Two reviewers extracted data separately and used the ROBINS-I tool to determine bias. The analysis included 13 trials with a total of 5040 patients (2365 outpatients and 2674 inpatients). Outpatient parotidectomy had a similar complication risk as inpatient surgery (Odds Ratio 0.69, 95% Confidence Interval: 0.49 to 0.98, p = 0.04). Haematoma and permanent facial nerve injury were much lower in outpatients. However, most research showed considerable selection and confounding biases. Outpatient parotidectomy is a safe and effective option for carefully chosen individuals. Standardised selection criteria can help enhance patient outcomes and surgical decision making.
Surgeons in the United Kingdom and the United States often perform identical oral and maxillofacial operations with strikingly different instrument sets. The extent and practical significance of this divergence have not, to our knowledge, been previously reported. We conducted a descriptive comparative review of contemporary UK and US practice (2023-2024), cataloguing instruments through clinical observation and discussions with peers and scrub teams, then verifying nomenclature, design, and provenance against reference texts and manufacturers' catalogues. Functionally equivalent but non-identical instruments were paired and profiled for origin, form, and typical use. Findings show a small common core (Freer elevator, Minnesota retractor, Austin retractor, DeBakey forceps, Adson forceps, Metzenbaum scissors, and Mayo scissors) with nearly all other instruments differing, illustrating parallel solutions to the same operative tasks. British instruments and their American counterparts (for example, Molt #9, Woodson #1, Seldin elevator, Molt #4, Dean scissors, Army-Navy retractor, Sweetheart retractor, Sistrunk retractor, Hargis retractor, 301 elevator, and Cogswell elevators) were assembled into a practical compendium, with the aim of encouraging cross-pollination of surgical practice. Awareness of transatlantic instrument choices presents an opportunity to refine one's armamentarium. Through selective adoption of unfamiliar but potentially advantageous instruments, the open-minded surgeon can discover new ways to enhance operative precision, efficiency, or ergonomics.
